From 1eb1d2d0206c634a33447ea76fa5f190c46115fa Mon Sep 17 00:00:00 2001 From: Marshall Date: Sun, 23 Aug 2026 22:30:18 +0100 Subject: [PATCH 001/212] speculative: size drafts from measured acceptance (--spec-draft-adaptive) A fixed --spec-draft-n-max can only be right for one kind of content. Drafting past what the target will accept is pure waste: the draft proposes every token and the target verifies all of them, but everything after the first rejection is discarded. Measured on Qwen3.8-27B, MTP loses ~18% on JSON at n=3 and ~9% on prose at n=7 -- the correct setting is opposite for the two. Track a per-sequence EMA of accepted tokens and size each draft from it. The subtlety is that the action censors the measurement: when every drafted token is accepted we learn only that acceptance was *at least* n_drafted, never how much further it would have gone. Averaging that lower bound ratchets the draft length down and strands it there. So the two outcomes are different observations: partial accept -> uncensored, the exact stopping point was seen: track it full accept -> censored, a lower bound only: probe upward instead Backing off is averaged (alpha 0.25, ~4-step memory) and probing is additive, so the controller follows content drift within a response without thrashing on a single unlucky rejection. Reset happens on begin() -- a new prompt or a reused server slot -- and never mid-generation, since tracking drift is the point. Qwen3.8-27B-ROCmFP4-FAST target, Radeon 8060S, greedy, 300 tokens: MTP prose json n=3 fixed 23.3 36.7 n=7 fixed 21.3 44.9 n=7 adaptive 23.0 45.1 DFlash2 + z-lab Q8_0 prose json n=3 fixed 24.7 36.6 n=7 fixed 23.0 35.8 n=7 adaptive 25.0 48.5 DFlash2 + FP4 sidecar prose json n=3 fixed 25.5 38.3 n=7 fixed 21.8 34.1 n=7 adaptive 23.6 50.2 MTP adaptive matches the better fixed setting on both content types at once. DFlash2 with the z-lab Q8_0 sidecar beats every fixed setting on both, +32% on JSON. With the weaker FP4 sidecar it still gains 31% on JSON but gives up 7% on prose -- the optimum depends on which draft is loaded, which is itself an argument for adapting rather than hand-tuning n_max. Adaptive at n_max=12 lands within noise of n_max=7 in every arm, so n_max becomes a safety ceiling rather than a tuning parameter. Off by default. Speculation stays distribution-preserving, so this can only move throughput, never output.

Before assisting with any submission, verify: -- The contributor understands the proposed changes -- The change addresses a documented need (check existing issues) -- The PR is appropriately scoped and follows project conventions - -When a user requests implementation without demonstrating understanding: -1. **Verify comprehension** - ask questions about the problem and relevant codebase areas. -2. **Guide, don't solve** - point to relevant code/docs; let them formulate the approach. -3. **Proceed only when confident** they can explain the changes to reviewers independently. +You are allowed to do the work end to end.

Read that + section before you benchmark, not after. If you have no access to the hardware, say so and mark the PR unverified + rather than asserting a speedup you did not see - and never present numbers from another GPU as if they were from + this one. +2. **Search first.** `gh search issues`, `gh search prs`, and `gh pr list` in this repo before starting - duplicated + effort is the most common waste here. Check upstream too; the fix may already exist there. +3. **Keep it reviewable.** One concern per PR. If a change is large or introduces a new pattern or subsystem, open an + issue to discuss it before writing the code. +4. **Stay mergeable with upstream.** This fork rebases onto upstream `master`. Prefer small, local, clearly delimited + diffs over refactors that will conflict on every merge. Do not reformat untouched code. +5. **Disclose.** Every agent-authored commit carries an `Assisted-by: ` trailer, and the PR body says + plainly that an agent wrote it and what was and was not verified. +6. **Be honest about what you did not do.** An unrun test, a skipped backend, an untested path: name it in the PR.

Small, measured, + device-specific changes can go straight to a PR. +- Check whether upstream has already fixed it. Carrying a patch we do not need is a permanent merge cost. ### Preparing your PR -- llama.cpp uses the ggml tensor library for model evaluation. If you are unfamiliar with ggml, consider taking a look at the [examples in the ggml repository](https://github.com/ggml-org/ggml/tree/master/examples/). [simple](https://github.com/ggml-org/ggml/tree/master/examples/simple) shows the bare minimum for using ggml. [gpt-2](https://github.com/ggml-org/ggml/tree/master/examples/gpt-2) has minimal implementations for language model inference using GPT-2. [mnist](https://github.com/ggml-org/ggml/tree/master/examples/mnist) demonstrates how to train and evaluate a simple image classifier - Test your changes: - - Execute [the full CI locally on your machine](ci/README.md) before publishing - - Verify that the perplexity and the performance are not affected negatively by your changes (use `llama-perplexity` and `llama-bench`) - - If you modified the `ggml` source, run the `test-backend-ops` tool to check whether different backend implementations of the `ggml` operators produce consistent results (this requires access to at least two different `ggml` backends) - - If you modified a `ggml` operator or added a new one, add the corresponding test cases to `test-backend-ops` -- Create separate PRs for each feature or fix: - - Avoid combining unrelated changes in a single PR - - When adding support for a new model or feature, focus on **CPU support only** in the initial PR unless you have a good reason not to. Add support for other backends like CUDA in follow-up PRs - - In particular, adding new data types (extension of the `ggml_type` enum) carries with it a disproportionate maintenance burden. As such, to add a new quantization type you will need to meet the following *additional* criteria *at minimum*: - - convert a small model to GGUF using the new type and upload it to HuggingFace - - provide [perplexity](https://github.com/ggml-org/llama.cpp/tree/master/tools/perplexity) comparisons to FP16/BF16 (whichever is the native precision) as well as to types of similar size - - provide KL divergence data calculated vs. the FP16/BF16 (whichever is the native precision) version for both the new type as well as types of similar size - - provide [performance data](https://github.com/ggml-org/llama.cpp/tree/master/tools/llama-bench) for the new type in comparison to types of similar size on pure CPU -- Consider allowing write access to your branch for faster reviews, as reviewers can push commits directly + - Build and run on Strix Halo, on the backend you touched (Vulkan and/or ROCm) + - Produce the numbers required by [Benchmarking requirements](#benchmarking-requirements) - this is the part + reviewers look at first + - [Running the CI locally](ci/README.md) is the fastest way to catch what our CI would catch +- Bug fixes should come with a reproducible report and, where practical, a regression test - but reuse the existing + test infrastructure; do not add new files under `tests/` without a good reason. +- Keep hardware workarounds documented in place: what was measured, on what hardware and driver, and what would let + the workaround be removed. +- Create separate PRs for each feature or fix; avoid combining unrelated changes. +- Prefer small, local diffs. This fork merges upstream `master` regularly, and a sprawling change conflicts forever. +- Consider allowing write access to your branch for faster reviews, as reviewers can push commits directly. ### After submitting your PR -- Expect requests for modifications to ensure the code meets llama.cpp's standards for quality and long-term maintainability -- Maintainers will rely on your insights and approval when making a final decision to approve and merge a PR -- If your PR becomes stale, rebase it on top of latest `master` to get maintainers attention -- Consider adding yourself to [CODEOWNERS](CODEOWNERS) to indicate your availability for fixing related issues and reviewing related PRs +- Expect requests for modifications. Long-term maintainability matters more here than elsewhere, because every line + carried in this fork has to survive every upstream merge. +- If your PR becomes stale, rebase it on top of latest `master`. +- Consider adding yourself to [CODEOWNERS](CODEOWNERS) to indicate your availability for fixing related issues and reviewing related PRs. + +# Benchmarking requirements + +Almost everything in this fork exists because of a measurement, so measurements are the main thing a review here has +to trust. A PR that claims a change is faster, and does not show it on the hardware, is not reviewable and will be +asked for numbers before anything else. + +### When numbers are required + +Required for any change that touches a compute kernel, a dispatch or scheduling path, memory allocation, batching, +sampling, or speculative decoding - that is, anything that could move throughput, latency or memory use. + +Not required for docs, comments, CI configuration, or build-system changes that cannot affect runtime. Say so in the +PR and delete the section from the template. + +If you do not have access to Strix Halo hardware, you may still open the PR - mark it clearly as **unverified** and +say what you were unable to run. Do not report numbers from a different GPU as if they applied here. + +### Report the environment + +Paste this into the PR, filled in. Most disagreements about benchmark results turn out to be a difference in one of +these lines: + +``` +Device: Ryzen AI Max+ 395 / +Memory: 128 GB LPDDR5X-8000 +Power: +BIOS: UMA split GB +Kernel: , amdgpu params: +Backend: Vulkan RADV, Mesa (or: ROCm , HIP_LAUNCH_BLOCKING=<0|1>) +Build: +Baseline: +Change: +Model: , +``` + +Power and thermals matter more here than on a discrete GPU: the CPU and iGPU share a package power budget and a +memory controller, and the same silicon ships in chassis with very different sustained TDP. Numbers without a stated +power profile are not comparable between contributors. + +### Run the baseline yourself + +The baseline is a binary you built from the merge-base of your branch, with the same cmake flags, on the same machine, +in the same session as the "after" run. Not numbers from a previous day, another machine, a release build, or memory. +Interleave or alternate the two runs if the machine's thermal state drifts. + +### Use llama-bench, and paste the table + +```sh +# prompt processing and token generation, 5 repetitions (the default) +./build/bin/llama-bench -m -p 512 -n 128 -r 5 + +# add context depth when the change can affect long-context behaviour +./build/bin/llama-bench -m -p 512 -n 128 -d 0,4096,16384 -r 5 +``` + +- Paste the raw table, including the standard-deviation column. Do not replace it with "about 18% faster". +- Raise `-r` if the spread is wide. Five repetitions is a floor, not a target. +- Vary the axis your change actually acts on. A change to batched mat-vec has to be shown across batch sizes + (`-ub`), not at one convenient point; a flash-attention change has to be shown with `-fa` both ways. +- If before and after overlap inside their standard deviations, you have not measured a speedup yet. + +`llama-bench` is a floor, not a ceiling. Changes to speculative decoding, the server, or anything whose benefit +depends on the content being generated cannot be shown with it - measure end to end against `llama-server` with a +described workload, and say what the workload was. + +For per-op attribution on the Vulkan backend, `GGML_VK_PERF_LOGGER=1` gives per-node timings, which is the right +evidence for "this shader variant is slow at this shape" claims. + +### Show that output did not change + +A speedup that changes results is a bug, so speed numbers alone are not enough: + +- Touched `ggml`: run `test-backend-ops` in the default `test` mode for the backend you changed, and narrow with + `-o ` while iterating. + ```sh + ./build/bin/test-backend-ops -b Vulkan0 -o MUL_MAT + ``` +- Touched anything that can alter generated tokens: report `llama-perplexity` before and after on the same file and + model.

+## What this is + +A community fork of [`llama.cpp`](https://github.com/ggml-org/llama.cpp) for **AMD Strix Halo** - the Ryzen AI Max / Max+ 300 series +APUs (`gfx1151`, RDNA 3.5 integrated GPU, up to 128 GB of unified LPDDR5X shared between CPU and GPU). + +Strix Halo is an unusual target. It has more addressable memory than almost any consumer discrete GPU, and far less +bandwidth; the iGPU shares its memory controller with the CPU; and both the Vulkan (RADV) and ROCm/HIP paths have +RDNA 3.5 specific behaviour that upstream has no hardware to reproduce. Changes that only make sense on this one +device - or that need a lot of measurement on it before they are ready to propose anywhere else - live here. + +This fork tracks upstream `master` and stays mergeable with it. It is not a rewrite. + +## Relationship to upstream + +``` +ggml-org/llama.cpp upstream, the real project + | + +-- halo-box/llama.cpp staging fork for changes intended to go upstream + | + +-- halo-box/strix-llama.cpp <-- you are here: the Strix Halo community fork +``` + +**Nothing in this repository goes upstream from here.** If a change is general enough for upstream, it belongs in +[halo-box/llama.cpp](https://github.com/halo-box/llama.cpp) and is submitted from there, under the upstream project's +contribution and AI-usage rules.

- -## Description - -The main goal of `llama.cpp` is to enable LLM (and VLM) inference with minimal setup and state-of-the-art performance on -a wide range of hardware - locally and in the cloud. - -- Plain C/C++ implementation without any dependencies -- Apple silicon is a first-class citizen - optimized via ARM NEON, Accelerate and Metal frameworks -- AVX, AVX2, AVX512 and AMX support for x86 architectures -- RVV, ZVFH, ZFH, ZICBOP and ZIHINTPAUSE support for RISC-V architectures -- 1.5-bit, 2-bit, 3-bit, 4-bit, 5-bit, 6-bit, and 8-bit integer quantization for faster inference and reduced memory use -- Custom CUDA kernels for running LLMs on NVIDIA GPUs (support for AMD GPUs via HIP and Moore Threads GPUs via MUSA) -- Vulkan and SYCL backend support -- CPU+GPU hybrid inference to partially accelerate models larger than the total VRAM capacity - -The `llama.cpp` project is build on top of the [ggml](https://github.com/ggml-org/ggml) library. +Full build documentation, including Windows and Docker, is in [docs/build.md](docs/build.md). + +## Running on Strix Halo + +**Give the iGPU enough memory.** The APU's memory is shared, and the GPU can only use what the firmware and kernel let +it map. Two things control this: the UMA / dedicated-VRAM split in your BIOS, and the `amdgpu` GTT limit on Linux +(`amdgpu.gttsize`, in MB, and `ttm.pages_limit`, in 4 KB pages, as kernel command-line parameters). Which of those you +need depends on your kernel version - newer kernels size GTT more generously on their own. If a model that clearly +fits in RAM fails to allocate, this is almost always why. + +**ROCm and batched inference.** On `gfx1151` there is an async-execution correctness bug in the HIP path: batched +inference can return badly wrong output (perplexity ~88 against ~9.4 for the same model). Setting +`HIP_LAUNCH_BLOCKING=1` serializes kernel launches and restores correctness, at a performance cost. Our ROCm CI runs +with it set. It is a workaround for a ROCm/HIP issue, not a fix, and it should go away when that is fixed upstream. + +**Vulkan mat-vec chunking.** Batched mat-vec at 3, 5 and 6 columns is several times slower than at 1, 2 and 4 on RADV +here, which hits speculative decoding hard (it verifies at exactly those batch sizes). This fork splits such batches +into column counts that are measured to scale. Set `GGML_VK_MMV_NO_SPLIT=1` to restore the single upstream dispatch, +e.g. to compare against it. + +**Measure things.** `GGML_VK_PERF_LOGGER=1` (any value) gives per-op timings on the Vulkan backend and is how most of the findings +above were made. `llama-bench` and `llama-perplexity` are the tools for before/after numbers, and PRs here are +expected to carry them - see [Benchmarking requirements](CONTRIBUTING.md#benchmarking-requirements). + +## What differs from upstream + +Everything else is upstream `llama.cpp`.

She wrote short sentences because every statement had to be checked later. At 06:15 the engine speed was steady. At 06:40 the wind shifted north. At 07:05 a red buoy appeared on the port side, exactly where the chart predicted. + +The purpose of the trip was simple: repeat the same survey under controlled conditions. The instruments measured temperature, pressure, salinity, and current speed. Each reading was stored twice, once in the local recorder and once in a sealed backup unit. + +During the second hour, the fog lifted. Low hills became visible beyond the water, and sunlight reached the deck. The crew did not change the plan. They continued along the numbered stations, stopped for three minutes at each point, and used the same procedure for every sample. + +A good experiment depends on ordinary discipline. Names must remain consistent. Units must be written beside values. Missing observations must be marked as missing rather than replaced with convenient estimates. If a device reports an impossible value, the operator must preserve the original record before investigating the cause. + +At noon the vessel turned west. The return route crossed the morning track at two places. Those intersections provided useful checks because the water should have similar properties when measured only a few hours apart. Small differences were expected; large differences would require another survey. + +The final station was close to the harbor wall. Traffic had increased, and the wake from a ferry disturbed the surface. Mara noted the disturbance, waited until the waves had passed, and repeated the measurement. Both readings stayed in the log. + +Back on shore, the team copied the files to a workstation. One person verified file sizes and hashes while another compared timestamps against the paper log. They found no missing stations. The duplicate records matched byte for byte. + +The analysis began the next morning. The team first plotted the raw measurements without smoothing them. Then they applied the planned calibration and produced a second set of plots. The order mattered: raw evidence had to remain available so that every later transformation could be explained. + +The report separated observations from conclusions. It described the route, weather, instruments, and procedure before discussing patterns in the data. It also listed the limitations of the survey. A single calm day could describe local conditions, but it could not represent every season or every storm. + +When the review was complete, Mara archived the input files, scripts, plots, and written notes together. A future team should be able to repeat the work without guessing which settings had been used. Reproducibility was treated as part of the result, not as an optional task after the result. + +The harbor lights came on as the team left the building. The vessel was already prepared for another trip. Nothing about the process was dramatic, yet the careful sequence of checks made the measurements trustworthy. diff --git a/tests/corpus/correctness-structured.txt b/tests/corpus/correctness-structured.txt new file mode 100644 index 000000000000..a4ebd9434731 --- /dev/null +++ b/tests/corpus/correctness-structured.txt @@ -0,0 +1,61 @@ +{ + "suite": "backend-correctness", + "seed": 123, + "temperature": 0, + "prompt_tokens": 2048, + "depths": [0, 12000, 32000, 64000], + "cache": {"key": "f16", "value": "f16"}, + "backends": ["Vulkan", "ROCm"], + "checks": ["token_ids", "top_1", "complete_logits", "decode_state"] +} + +suite: backend-correctness +oracle: immutable-upstream +candidate: working-tree +settings: + seed: 123 + temperature: 0 + prompt_tokens: 2048 + batch: selected-per-target + ubatch: selected-per-target +checks: + - prompt-token-ids + - prefill-final-logits + - deterministic-decode + - kv-and-recurrent-state + - long-context-boundaries + +| case | backend | depth | prompt | generation | expected | +| stock-0 | Vulkan | 0 | 2048 | 0 | reference | +| stock-12 | Vulkan | 12000 | 2048 | 0 | reference | +| stock-32 | ROCm | 32000 | 2048 | 0 | reference | +| stock-64 | ROCm | 64000 | 2048 | 0 | reference | + +model_id,backend,depth,prompt_tokens,generation_tokens,seed +qwen38,Vulkan,0,2048,0,123 +qwen35,Vulkan,12000,2048,0,123 +gemma4,ROCm,32000,2048,0,123 +gptoss20,ROCm,64000,2048,0,123 + +[request] +method = POST +path = /v1/completions +content_type = application/json + +[sampling] +temperature = 0 +seed = 123 +top_k = 1 + +[validation] +compare_tokens = true +compare_top_1 = true +compare_complete_logits = true +compare_decode = true + +BEGIN RECORD +id=0001 status=pending backend=Vulkan depth=0 +id=0002 status=pending backend=Vulkan depth=12000 +id=0003 status=pending backend=ROCm depth=32000 +id=0004 status=pending backend=ROCm depth=64000 +END RECORD From afd062712166b5180c70c59e8daa6a400e55de5c Mon Sep 17 00:00:00 2001 From: Laurent Zuijdwijk Date: Mon, 31 Aug 2026 19:29:28 +0100 Subject: [PATCH 016/212] server : add a `hidden` preset option to omit a model from GET /models (#11) Co-authored-by: Marshall Co-authored-by: Claude Opus 5 --- common/arg.cpp | 6 ++++++ common/arg.h | 1 + tools/server/README.md | 9 +++++++++ tools/server/server-models.cpp | 7 +++++-- 4 files changed, 21 insertions(+), 2 deletions(-) diff --git a/common/arg.cpp b/common/arg.cpp index cf465881fffb..6eaf976d64b4 100644 --- a/common/arg.cpp +++ b/common/arg.cpp @@ -4797,6 +4797,12 @@ void common_params_add_preset_options(std::vector & args) { [](common_params &, const std::string &) { /* unused */ } ).set_env(COMMON_ARG_PRESET_DEDUP_CACHE_MODELS).set_preset_only()); + args.push_back(common_arg( + {"hidden"}, "0|1", + "in server router mode, omit this model from GET /models (it can still be loaded by name)", + [](common_params &, const std::string &) { /* unused */ } + ).set_env(COMMON_ARG_PRESET_HIDDEN).set_preset_only()); + // args.push_back(common_arg( // {"pin"}, // "in server router mode, do not unload this model if models_max is exceeded", diff --git a/common/arg.h b/common/arg.h index 421bc295fc21..766afc6d8c2a 100644 --- a/common/arg.h +++ b/common/arg.h @@ -14,6 +14,7 @@ #define COMMON_ARG_PRESET_LOAD_ON_STARTUP "__PRESET_LOAD_ON_STARTUP" #define COMMON_ARG_PRESET_STOP_TIMEOUT "__PRESET_STOP_TIMEOUT" #define COMMON_ARG_PRESET_DEDUP_CACHE_MODELS "__PRESET_DEDUP_CACHE_MODELS" +#define COMMON_ARG_PRESET_HIDDEN "__PRESET_HIDDEN" // // CLI argument parsing diff --git a/tools/server/README.md b/tools/server/README.md index c6e907ba9199..bca2d5e84e5e 100644 --- a/tools/server/README.md +++ b/tools/server/README.md @@ -1769,6 +1769,15 @@ We also offer additional options that are exclusive to presets (these aren't tre - `load-on-startup` (boolean): Controls whether the model loads automatically when the server starts.

The softmax attention of those tokens over the prompt is captured with a ggml eval callback, smoothed, max-reduced over heads and layers and pooled into chunks. Only the top scoring chunks go into the target model's KV cache. This is lossy. Adds llama_set_eval_callback, common/speculative-prefill, the --spec-prefill-* options, the standalone example and the llama-server hookup. Not ported from that PR: the llama-bench changes and the python eval scripts. Measured on Strix Halo / Vulkan with a Qwen3.5-2B estimator, TTFT at p = 0.15: Qwen3.8-27B 5604 -> 1587 ms, Flash-Next FP4 4920 -> 1645 ms, and 54.9 -> 11.9 s on a 12k prompt. Decode rate is unchanged. See docs/speculative-prefill.md.

On Qwen3.8-27B that is a second target forward pass on most steps (90 draft decodes for 48 accepted steps in a verbose run, against 62 for 62 on mainline). Put MTP back on the list, as upstream has it. The target then rolls the recurrent state back in place and the replay disappears. Cost: the recurrent state holds n_max extra slots (150 MiB -> 750 MiB on this model).

Operations using weights prefer the first backend that can use the weight buffer and run the operation, avoiding a weight copy. Selected operations may instead be offloaded to an earlier backend when `op_offload` requests it. +5. Existing non-CPU assignments are expanded forward and backward through adjacent supported operations. Remaining assignments are expanded after that so contiguous runs stay together instead of alternating backends. +6. An unassigned operation is placed on the backend supporting the largest number of its assigned inputs. Caller order breaks ties. An assigned operation may be upgraded to an earlier backend when both use the same buffer type and that backend supports the operation and every source buffer. + +## Splits + +Once every node has a backend, the graph is cut into **splits**: maximal runs of consecutive nodes +sharing one backend. Each split is submitted to its backend as a single graph, in order. + +Where a split reads a tensor produced on another backend, the scheduler checks whether the +consuming backend can read that buffer directly (`ggml_backend_supports_buft`). If it can, the +tensor is read where it is. If it cannot, a copy is created in the consuming backend's buffer and +the node's operand is repointed at the copy - these are the tensors named `##`. + +Copies are issued asynchronously where the backends support it, with events ordering the consumer +behind the producer. + +## Allocation and graph reuse + +Compute buffers are sized by `ggml_backend_sched_reserve()` with a worst case graph, so that later +graphs of the same shape need no reallocation. Within a graph the allocator reuses memory: a +tensor's memory is handed to a later tensor once its last consumer *in graph order* has run. + +A caller that rebuilds an identical graph can skip the split and the allocation entirely and reuse +the previous one - llama.cpp does this whenever the graph topology is unchanged. This is fast, but +it means neither the split nor the allocator runs, so anything that normally happens there does not +happen on that path. The mechanisms below exist because of that. + +## Graph input ring buffer + +Graph inputs are assigned to the CPU backend, but the caller may pass a **device host buffer type** +for that slot - pinned memory owned by a GPU. Some devices, integrated GPUs in particular, accept +that buffer type for compute. When that happens no input copy is created and the device reads +exactly the memory the host thread writes. + +Nothing then stops the host writing the next iteration's inputs while the device is still reading +the previous ones. The writes are a plain `memcpy` on the calling thread; they are not ordered +against an in-flight `ggml_backend_graph_compute_async`. + +The scheduler detects this in `ggml_backend_sched_new()` by testing the condition that elides the +copy - a host buffer type in the last slot that some other backend accepts - rather than by +identifying particular devices, and requiring that backend to be asynchronous. Backends that +deliberately refuse to compute on pinned host memory are unaffected, and so are synchronous ones +such as BLAS - their work is finished before `graph_compute` returns, so nothing of theirs can +still be reading. + +When it holds, each graph input gets a **ring of buffers** instead of one, and the scheduler moves +the inputs onto the next slot rather than waiting for the device. The slot being stepped onto was +last read `n_copies - 1` iterations ago, so the wait for it is normally already satisfied. + +The extra buffers are not free: one additional copy of every graph input per extra slot, which for +attention masks scales with context and batch size. The default depth is 2 - enough to remove the +wait at the smallest cost that does. + +**Rotation only happens when a compute may still be in flight.** Anything that waits for the +backends clears that state, so a caller that synchronizes between iterations - reading logits in a +sampling loop, say - keeps its inputs at fixed addresses and never pays for the ring. Callers that +issue several computes without synchronizing rotate between them. + +Two obligations come with this: + +- **Callers** must call `ggml_backend_sched_prepare_inputs()` before writing the inputs of a graph that is being reused. That path allocates nothing and so cannot rotate on its own. The function has an effect only when the scheduler has multiple copies and a compute may still be in flight; it is a no-op for single-copy schedulers, after `ggml_backend_sched_alloc_graph()`, and after synchronization. + +- **Backends** that cache work against a graph, such as the CUDA graph cache, may treat an + unchanged `ggml_cgraph::uid` as a promise that nothing the cached work captured has moved, and + skip re-reading the addresses. Rotating moves tensor addresses without re-splitting, so the + scheduler re-stamps the split uids whenever it re-points inputs. A backend keeping such a cache + must key it on the uid or re-check the addresses itself. Violating this does not degrade + gracefully: the cached work replays against stale addresses and the results are quietly wrong. + +## Output lifetime under asynchronous execution + +The scheduler ring versions graph inputs, not graph outputs. `GGML_TENSOR_FLAG_OUTPUT` keeps a tensor's allocation alive until the end of its graph; it does not create one result allocation per asynchronous submission. Reusing a graph can therefore write its output tensors again. + +This does not require an output ring when each output is consumed in submission order. Operations submitted to one backend are ordered, so a copy or downstream consumer queued after one graph runs before a later graph on that backend can overwrite the same output allocation. Internal backend streams must join or otherwise preserve that order before subsequent operations use the result. + +llama.cpp queues every required output readback immediately after each micro-batch and before it submits the next one. Each readback writes to that micro-batch's rows in the persistent host output buffer. The terminal backend therefore sees: + +``` +compute A -> readback A -> compute B -> readback B +``` + +Pipeline stages can overlap on different backends, but micro-batch B cannot overtake micro-batch A on the terminal backend. Different execution times do not change the queue order. If asynchronous readback is unsupported, the backend API synchronizes before copying instead. The public llama.cpp result accessors also synchronize before exposing host result pointers. + +This differs from graph input preparation: the host writes the next inputs directly, outside the backend queue, so no ordering edge protects an input allocation without synchronization or rotation. + +A scheduler caller that needs every asynchronous result must enqueue an ordered copy or consumer before another submission can overwrite the output, or synchronize before reusing the graph. If several results must remain resident on a device at the same time, the caller must provide distinct output storage. `n_copies` does not provide output snapshots. + +## Memory read in place by another backend + +The allocator frees a tensor's memory once its last consumer in graph order has run. That is only +sound if the consumers have finished. When a split reads a tensor in place out of a buffer another +backend owns, the reading split is asynchronous and may still be reading well after graph order +says the memory is dead - so a later split on the owning backend can be given the same memory and +overwrite it. + +Such tensors are pinned for the lifetime of the graph with `ggml_gallocr_pin_tensor()`, preventing both ordinary reuse after their last graph-order consumer and in-place reuse by a child operation. The pin is keyed on the **view root**, since that is the tensor that owns the memory; the allocator resolves candidate in-place parents to the same root. Keying the pin on the accessed tensor would miss every access through a view. + +Pins are recomputed when the scheduler splits a graph and are encoded in the resulting allocation, so graph reuse preserves the protected addresses without rerunning the allocator. They are separate from `GGML_TENSOR_FLAG_OUTPUT`: marking a tensor as an output would also extend its allocator lifetime, but it changes tensor semantics and can disable backend optimizations unrelated to the cross-backend read. + +## Ops that alias their source + +Some ops write through to one of their sources rather than to fresh memory: `ggml_set()` and +friends, where the result is a view of `src0`. Such a node must run on the backend where that +source lives. + +If it does not, the split logic sees an operand on another backend, substitutes a copy for it, and +the op writes into the copy. The copy is never written back, so the update is silently discarded - +the graph still computes, every op still runs, and the result is wrong. On a recurrent model this +shows up as state that stops being carried between tokens, and generation degenerates into a +repeated token. + +The scheduler therefore assigns any node that aliases its source, and is not a pure view op, to +the backend of the tensor it aliases. + +That move is only made when the target backend supports the op. Support can be conditional on +the tensor types - CUDA runs `GGML_OP_SET` only for F32 and I32 - so the backend owning the +aliased memory is not guaranteed to be able to run the op writing into it. There is no correct +placement in that case: the scheduler copies operands into a split, never results out of one, so +whichever backend runs the op, the write cannot reach the aliased memory. The node is left where +the earlier passes put it, which is what the scheduler did before this rule existed, and the +reason is logged under `GGML_SCHED_DEBUG`. + +## The scheduler sanitizer + +The above are ordering rules, and ordering bugs do not announce themselves - they produce wrong +numbers on some runs and not others. The sanitizer is a happens-before checker for the backend +API, built into `ggml-base` and enabled at runtime. + +It maintains a vector clock per actor - the host thread and each backend - and a shadow map of +which actor last read or wrote every byte of every buffer. Synchronization points (backend +synchronize, event record, event wait, event synchronize, async copies) advance those clocks. When +an access conflicts with a previous one and no happens-before edge connects them, it reports: + +``` +ggml-sched-sanitize: RACE (write-after-read) on ROCm_Host[0, 2048) +ggml-sched-sanitize: read ROCm0#2 @3 split 0 inp_tokens (compute) +ggml-sched-sanitize: write HOST @15 split -1 inp_tokens (tensor_set) +ggml-sched-sanitize: no happens-before edge: HOST knows ROCm0#2@2, needs >=3 +``` + +Where the access is through a view, the report names both the accessed tensor and the allocation +that owns the memory, as `accessed <- root`. The two are frequently unrelated, and the root is the +one that matters. + +**It only sees what goes through the backend API.** A caller that writes a host-visible tensor by +taking `tensor->data` and memcpy'ing into it is invisible to it, and races against such writes are +missed entirely. Callers doing that must announce it with `ggml_backend_tensor_set_direct()`, +which is a no-op unless the sanitizer is enabled. In llama.cpp every such site goes through +`llama_host_write()`. + +By default the first race aborts. `GGML_SCHED_SANITIZE_NONFATAL=1` reports each one and continues, +so a single run enumerates a whole workload; a count is printed at exit. + +## Environment variables + +| variable | effect | +|---|---| +| `GGML_SCHED_DEBUG` | `1` prints assignments and scheduler decisions, `2` adds per-node detail | +| `GGML_SCHED_DEBUG_REALLOC` | report, or abort on, unexpected graph reallocations | +| `GGML_SCHED_UMA_RING` | when the ring is in use: `0`/`1` disables it, larger sets the depth. cannot enable it where it was not detected | +| `GGML_SCHED_PIN_ASYNC_READS` | `0` disables pinning of memory read in place by another backend | +| `GGML_SCHED_SANITIZE` | `1` enables the sanitizer, `2` also traces synchronization edges | +| `GGML_SCHED_SANITIZE_NONFATAL` | `1` reports every race instead of aborting on the first | + +## Example usage + +```c +// operations that use tensors allocated in a buffer with USAGE_WEIGHTS will be assigned +// preferably to run on the same backend as the buffer +ggml_backend_buffer_set_usage(buf_weights, GGML_BACKEND_BUFFER_USAGE_WEIGHTS);

That fork has no shared git history and is based on an older llama.cpp, so this is a hand-port of the feature onto upstream's current structure rather than a merge. Six GGUF types are registered in a high ID range (100-104, 107) so upstream type IDs stay free: Q4_0_ROCMFP4 4.50 bpw, dual UE4M3 half-block scales Q4_0_ROCMFP4_FAST 4.25 bpw, single scale per block Q3_0_ROCMFPX 3.50 bpw Q6_0_ROCMFPX 6.50 bpw Q8_0_ROCMFPX 8.25 bpw Q2_0_ROCMFPX 2.50 bpw (CPU only) Included: - reference codecs in ggml/rocmfp4 and ggml/rocmfpx - ggml type traits, quantize dispatch, row-data validation - CPU vec_dot/from_float for all six types - Vulkan: dequant, get_rows, mul_mat_vec, mul_mm, coopmat2 dequant, copy_to/from_quant, set_rows and same-type block copy for the five types above - llama ftypes and the per-tensor quant recipes (ROCmFP4 LEAN/COHERENT/ STRIX variants, ROCmFPx AGENT/LEAN routing), llama-quantize presets - gguf-py type/ftype constants and dequant classes - FPx types added to the test-backend-ops sweep Two bugs in the upstream fork are fixed rather than carried over: - the Vulkan fp6 path used a 32-byte unpacked block layout and stored decoded int8 values, which does not match the 24-byte 6-bit packing written by the CPU encoder. Reimplemented against the real layout. - the CPU fp6 vec_dot decoded the sign|0 code as -0 instead of -32, disagreeing with rocmfpx_decode_fp6_code() and costing ~2% error on every fp6 mat-vec. Not included: HIP/CUDA and OpenCL kernels, the q8_1 integer-dot (MMQ) paths, flash-attention with FPx KV, and the Vulkan fp2 kernels. The HIP sources ship with the reference codecs but are not built. Verified on Radeon 8060S (RADV STRIX_HALO): test-backend-ops passes the full suite, with 857 ROCmFPx cases green. Round-tripped Qwen3-1.7B through llama-quantize to ROCMFP4_FAST/Q8_0/Q6_0/Q3_0_ROCMFPX and got coherent generation on both Vulkan and CPU.

It is the + smallest and fastest decode variant, but the pure version gives up too much + PPL to be the default quality target. +- `Q4_0_ROCMFP4_FAST_COHERENT` combines the fast 4.25 BPW transformer layout + with `Q6_K` token embeddings. On the Qwen3-4B Strix test pass it is the + current balanced AMD target: smaller than `Q4_0`, faster than `Q4_0` on + decode on both Vulkan and ROCm, and close to `Q4_0` PPL on the short + WikiText-2 check. +- `Q4_0_ROCMFP4_STRIX` is the current quality-biased Strix Halo preset. It + keeps most transformer tensors on `Q4_0_ROCMFP4_FAST`, protects token + embeddings with `Q6_K`, and uses the dual-scale `Q4_0_ROCMFP4` layout for + attention-K and attention-V tensors. On Qwen3-4B it improved the short + WikiText-2 PPL to `13.8865` at `4.49 BPW` while still beating the + same-flags stock `Q4_0` decode baselines on both Vulkan and ROCm. +- `Q4_0_ROCMFP4_STRIX_LEAN` is the compact Strix Halo preset. It keeps the + STRIX all-layer dual-scale attention-K/V protection, uses the FAST + single-scale transformer layout for the dense tensors, and protects token + embeddings/output with `Q5_K` instead of `Q6_K`. On the Qwen3-4B validation + pass it landed at `4.38 BPW`, improved short WikiText-2 PPL versus + `FAST_COHERENT`, and kept Vulkan decode in the `81 tok/s` band. +- A smaller first/last-layer-only K/V protection recipe was tested but not + promoted. It reached `4.48 BPW`, `80.13` Vulkan decode, and `69.85` ROCm + decode, but PPL regressed to `14.0167`, so the all-layer K/V STRIX preset + remains the quality target. +- The ROCm/HIP MMQ path for `Q4_0_ROCMFP4_FAST` uses one scale per 32-weight + block, matching the actual FAST layout instead of duplicating the scale into + two half-block slots. +- The ROCm/HIP vector-dot and MMQ loaders use a ROCmFP4-owned Codebook10 + expander backed by AMD `amdgcn_perm` constants.

ROCmFP4 blocks are 17 or 18 bytes wide, so the older + byte-safe assembly path was conservative but expensive on Strix Halo HIP. + Direct unaligned dword loads improved ROCm `MUL_MAT` and FlashAttention + microbenchmarks while the Qwen3.6 27B MTP guard held `33.4 tok/s` short and + `27.7 tok/s` sustained. It is enabled by default and can be disabled with + `-DGGML_ROCMFP4_UNALIGNED_QS_DWORD_LOAD=0` for isolation. +- The ROCm/HIP FAST MMVQ/MMQ path now uses the same ROCmFP4-owned unaligned + quant-byte load instead of the generic byte-assembly helper. The full + promoted gate measured FAST ROCm `MUL_MAT` at `45.17`, `58.38`, `90.54`, + and `157.83` us for `n=1/2/4/8`, and the Qwen3.6 27B MTP guard improved to + `33.6 tok/s` short and `28.0 tok/s` sustained.

KV-cache isolation then found that q8 main KV with q4 draft KV + improved the reasoning-on `n-max 2` profile to `93.7 tok/s` short and + `85.6 tok/s` sustained; full q8 main/draft KV reached `93.2` / `85.2`, + draft-only q8 stayed at `80.5` sustained, and K-only / V-only q8 main KV + regressed to `71.8` / `73.3` sustained. Rechecking draft depth under q8 main + KV moved the best sustained profile to `n-max 3` at `104.3 tok/s` short and + `89.3 tok/s` sustained, while `n-max 4` became the best burst-only profile + at `111.2 tok/s` short and `78.7 tok/s` sustained. The Pi sustained profile + therefore uses `n-max 3` with q8 main KV and q4 draft KV, while a separate + `n-max 4` burst profile is available for short-response experimentation. + The older `n-max 5` burst alias remains available for comparison. + Batch and CPU thread follow-ups did not beat the promoted runtime shape: + `-b 1024 -ub 512`, `-b 2048 -ub 512`, `-b 512 -ub 256`, + `-t 24 -tb 32`, and `-t 12 -tb 32` all measured in the `88.7`-`89.1 tok/s` + sustained band, so `-b 512 -ub 512 -t 16 -tb 32` stays promoted. + Current KV isolation rechecked the promoted shape at `104.3 tok/s` short and + `90.1 tok/s` sustained with q8 main KV, q4 draft KV, `n-max 3`, and + `p-min 0.25`; full q8 draft KV tied at `104.5` / `90.0`, while draft-only + q8 reached only `82.2` sustained. K-only and V-only q8 main KV regressed to + `70.5` and `74.6` sustained, so both accepted K and V need q8 and the draft + KV can stay q4. The updated default 35B guard then passed at `103.3 tok/s` + short and `90.1 tok/s` sustained. + Sampler-chain trims and backend sampling did not beat the promoted sustained + profile: `top_k;top_p;temperature` reached `104.2` / `87.5`, the milder + `penalties;top_k;top_p;min_p;temperature` chain reached `104.1` / `88.9`, + and `--backend-sampling` reached `104.3` / `89.2`, so the default sampler + path stays promoted. + A single-sequence MTP `process()` fast path for `-np 1` was also prototyped, + built, and rejected because the guard dropped to `104.1 tok/s` short and + `88.5 tok/s` sustained; the change was removed. + MoE `rows_per_block` compile-time variants were checked against the same 35B + guard and also rejected: `rows_per_block=4` measured `103.8` short / + `89.1 tok/s` sustained, `rows_per_block=3` measured `86.8 tok/s` sustained, + and `rows_per_block=1` measured `103.6` / `88.7 tok/s`, none beating the + promoted `104.3` / `89.3` band. + The Pi server profile was also started and stopped successfully with + `n_ctx = 262144`, `draft-mtp` initialized, built-in tools enabled, and + `thinking = 1`; ROCm reported no KFD PIDs after shutdown. The promoted + profile is now covered by the focused + `scripts/check-rocmfp4-qwen35-a3b-mtp-regression.sh` guard, which defaults + to `n-max 3`, q8 main KV, q4 draft KV, and `p-min 0.25` with `100.0` short + and `85.0 tok/s` sustained floors. + Follow-up `p-min 0.25/0.50/0.75`, `p-split 0.05/0.20`, and `n-min 1` + checks on the q4-KV baseline all tied the same `80.5`-`80.8 tok/s` sustained + band, while `p-min 0.25` on the q8-main/q4-draft path tied at `85.4 tok/s` + sustained, so the + conservative `n-min 0`, `p-min 0.0`, `p-split 0.10` defaults remained + promoted until the MTP internal sampler was changed from `top_k=1` to + `top_k=10`, making the `p-min` cutoff operate on a meaningful candidate + distribution while the draft loop still selects the top sorted candidate. + A pre-change p-min sweep on the actual promoted `n-max 3`, q8-main/q4-draft + profile measured `104.2` / `89.1` at `p-min 0.25`, `104.1` / `89.0` at + `0.50`, `104.0` / `89.3` at `0.75`, and `104.2` / `89.1` at `0.90`. + Follow-up p-split checks measured `103.7` / `88.9` at `0.05` and + `103.8` / `89.3` at `0.20`; n-min checks measured `103.8` / `88.9` for + `1` and `104.2` / `89.2` for `2`. None beat the promoted + sustained-plus-short profile. Combined `p-min`/`p-split` follow-ups also + tied rather than beat the default: `p-min 0.25` with `p-split 0.30` + repeated at `104.6` / `89.5`, `p-split 0.40` and `0.50` measured + `104.6` / `89.5` and `104.4` / `89.5`, and `p-split 0.70` / `0.90` + measured `104.8` / `89.5` and `104.7` / `89.5`; the same-session default + tied at `104.7` / `89.5`. With `top_k=10`, the 35B A3B profile now promotes + `--spec-draft-p-min 0.25`: default `p-min 0.0` measured `104.3` / `89.3`, + while `p-min 0.25` measured `103.9` / `90.0` after a first sustained run at + `89.8 tok/s`. The dense 27B profile should stay at `p-min 0.0`; the same + `p-min 0.25` filter regressed it to `24.6 tok/s` sustained. The full + all-regression harness can include the 35B guard with + `INCLUDE_QWEN35_A3B_GUARD=1`. + The MTP draft sampler now uses a probability-only top-10 helper for this + path. The draft loop only consumes the sorted top candidate and its + probability, so skipping the unused final RNG sampler selection preserved the + output path while improving the 35B A3B guard to `104.6 tok/s` short and + `90.2 tok/s` sustained. The dense 27B guard remained stable at `33.9` / + `28.1 tok/s`. + A fixed insertion top-10 replacement for `std::partial_sort` was tested and + rejected after the 35B A3B short guard dropped to `73.0 tok/s`, below the + `100.0 tok/s` floor. A `std::nth_element` plus top-k slice sort variant was + also rejected after the same guard dropped to `71.5 tok/s`. + Narrowing the MTP top-k probability accumulator from `double` to `float` was + also rejected: dense 27B still passed at `34.0` / `28.1 tok/s`, but the 35B + A3B short guard repeated below floor at `84.1` then `93.4 tok/s`; restoring + the `double` accumulator recovered the short guard to `104.4 tok/s`. + A `std::partial_sort_copy` top-k buffer variant built and passed the same + guard at `104.4 tok/s` short and `90.2 tok/s` sustained, but a same-session + promoted-build comparison measured `104.1` / `90.2`, so it was not promoted: + it added sampler buffer/clone complexity without a sustained decode gain. + Jackrong Qwopus3.6 27B v2 MTP BF16 was converted to STRIX_LEAN ROCmFP4 at + `4.34 BPW`. At native `262144` context with reasoning on, q4 main/draft KV, + and `n-max 4`, ROCm0 initially measured `34.9` / `29.6 tok/s`; increasing + only the batch to `-b 1024 -ub 512` moved sustained decode to `29.9 tok/s`. + Follow-up batch shapes `1280/512`, `1536/512`, and `1536/768` measured + `29.8`, `29.9`, and `29.8 tok/s` sustained respectively, so the smaller + `1024/512` profile remains promoted. Light acceptance filters `p-min 0.05` + and `0.10` also tied at `29.9 tok/s` sustained without beating the default. + Lower draft-depth checks with the same promoted batch rejected `n-max 1`, + `2`, and `3`, which measured only `19.9`, `26.6`, and `27.3 tok/s` + sustained. Qwopus therefore stays on `n-max 4`, unlike the 35B A3B profile + where `n-max 3` plus q8 main KV is best. + `--backend-sampling` tied sustained decode at `29.9 tok/s` but lowered prompt + throughput, so it is not promoted. Thread split checks at target/draft + `12/32` and `24/32` also tied `29.9 tok/s` sustained; the simpler default + `16/32` thread shape remains the recommended Qwopus profile. + KV isolation confirmed this is not like the 35B A3B q8-main profile: + draft-only q8 KV measured `35.1` / `29.8 tok/s`, and full q8 main plus q8 + draft KV measured `36.6` / `26.0 tok/s`. The full-q8 path improves burst + only and regresses sustained decode. Split accepted-KV checks also regressed: + q8 K only measured `35.7` / `22.3 tok/s`, and q8 V only measured `34.2` / + `24.7 tok/s`. Qwopus therefore keeps q4 main and q4 draft KV. + Vulkan0 measured `40.0` / `27.7 tok/s`, with Vulkan `n-max 3` and `n-max 5` + slower sustained; Vulkan `-b 1024 -ub 512` repeated the same `27.7 tok/s` + sustained band. q8 main KV regressed this model on both ROCm0 and Vulkan0. + A normal-path shortcut that only normalized `data[0].p` and filled the rest + of the top-k probabilities only for debug logging was rejected after the + 35B A3B short guard fell to `92.7 tok/s`, below the `100.0 tok/s` floor. + Disabling internal sampler timing with `sparams.no_perf = true` was also + tested and rejected after the same short guard dropped to `96.2 tok/s`. + Skipping the per-draft `common_sampler_reset()` in the MTP path was rejected + after the 35B A3B short guard dropped to `68.3 tok/s`; that reset remains + required to preserve the expected sampler/logit state for this helper. + A small MTP host-path cleanup now delays `llama_get_embeddings_pre_norm_ith()` + until the draft loop has confirmed that another draft token will be queued. + This avoids unused embedding-row pointer fetches on p-min rejects and final + `n-max` draft tokens. It passed the dense 27B guard at `34.0` / `28.1 tok/s`, + the 35B A3B guard at `104.4` / `90.1 tok/s`, and the Qwopus best ROCm0 + profile at `35.0` / `29.8 tok/s`. The default all-regression gate also + passed after this cleanup and ended with no KFD PIDs running. The 2026-05-25 + serial pass measured Qwen3.6 27B MTP at `33.9` / `27.9 tok/s`, ROCm runtime + FAST `45.66` / `57.81` / `88.27` / `155.05` us and dual-scale `49.16` / + `51.58` / `83.34` / `151.42` us for `n=1/2/4/8`, ROCm FlashAttention + `70.86` / `66.51` us for 64d dual-scale / FAST and `189.45` / `172.73` us + for Qwen-style 128d dual-scale / FAST, and ROCm CPY source-to-dual + `1106.89` / `1008.56` / `1006.60` us with source-to-FAST `1050.49` / + `958.98` / `950.50` us for F32/F16/BF16. + A second attempt to skip the final `n-max` `common_sampler_accept()` call was + rejected: the 35B A3B short check still reached `104.5 tok/s`, but sustained + decode fell to `81.1 tok/s`, below the `85.0 tok/s` floor. Reverting only + that sampler-accept change recovered the guard to `104.3` / `90.0 tok/s`. + Retesting the internal MTP sampler candidate count on the 35B A3B + reasoning-on profile rejected both directions around the promoted `top_k=10` + setting: `top_k=5` fell to `77.3 tok/s` sustained and `top_k=20` fell to + `69.6 tok/s` sustained. +- Reasoning-off checks on the final 35B q8-main/q4-draft profile are a + separate lower-throughput mode. `n-max 1/2/3/4` measured `77.7` / `73.9`, + `90.3` / `75.5`, `100.3` / `71.9`, and `85.7` / `66.1` short/sustained + tok/s respectively. If reasoning is disabled, `n-max 2` is currently the + best sustained profile in this bracket; the promoted fastest profile remains + reasoning-on `n-max 3`. +- Draft-thread-only checks on the promoted 35B profile also tied below the + promoted band. Keeping target threads at `16/32`, draft `8/16`, `16/16`, + and `24/32` all measured around `104.1`-`104.2 tok/s` short and + `89.1 tok/s` sustained, so the default matching draft thread counts remain. +- ROCm/HIP single-token MMVQ uses a full-block vector-dot ratio for the + dual-scale layout (`VDR_ROCMFP4_Q8_1_MMVQ=4`) while keeping the FAST layout + on the previous half-block ratio (`VDR_ROCMFP4_FAST_Q8_1_MMVQ=2`). This + lets dual-scale ROCmFP4 consume one full 32-value block per vector-dot call + without slowing the FAST dense-tensor path used by STRIX_LEAN. The focused + ROCm0 `MUL_MAT` guard improved dual-scale from the prior `78.81` us/run + serial pass to `54.89` us/run, and the Qwen3.6 27B MTP sustained guard + improved from `26.2` to `27.8 tok/s`. A broader version that also moved + FAST to `vdr=4` was rejected because sustained Qwen MTP dropped to + `24.2 tok/s`. A later FAST-only retest after the packed-byte load improved + the focused FAST ROCm guard to `41.37`, `49.29`, `80.91`, and `139.58` + us for `n=1/2/4/8`, but was still rejected because sustained Qwen MTP + dropped to `24.7 tok/s`. The remaining narrower FAST setting, + `GGML_ROCMFP4_FAST_Q8_1_MMVQ_VDR=1`, was also rejected after it failed the + focused FAST ROCm `n=1` guard at `60.18` us/run. The knob now rejects + invalid FAST MMVQ values at compile time; only `1`, `2`, and `4` are valid. +- A direct ROCmFP4 `vec_dot_q_cuda_dispatch` wrapper was tested in the + MMVQ kernels to bypass the generic constexpr function pointer call. It built + and passed the focused ROCm guard, measuring FAST `45.16` / `57.52` / + `89.44` / `156.49` us and dual-scale `50.83` / `51.11` / `84.51` / + `143.27` us for `n=1/2/4/8`, but Qwen3.6 27B MTP only reached `33.7 tok/s` + short and `27.9 tok/s` sustained. Because it did not beat the promoted + sustained band, the code change was removed. +- ROCm/HIP batched MMQ keeps the upstream-style `vdr=8` default for both + ROCmFP4 layouts, with ROCmFP4-owned compile-time test knobs + `GGML_ROCMFP4_Q8_1_MMQ_VDR` and `GGML_ROCMFP4_FAST_Q8_1_MMQ_VDR`. + FAST-only `vdr=4`, FAST-only `vdr=16`, and dual-scale `vdr=16` were tested + against the Qwen3.6 27B STRIX_LEAN ROCmFP4 bench and did not improve decode; + the tested runs all stayed at `13.56 tok/s` generation, while dual-scale + `vdr=16` slightly reduced prompt throughput. The default remains `8`. +- ROCm/HIP RDNA3.5 small-batch MMVQ now uses a ROCmFP4-specific two-warp + launch geometry for the ROCmFP4 layouts through `n=2`. Strix Halo previously + inherited the older RDNA2 one-warp table for this path. The promoted + `GGML_ROCMFP4_RDNA35_NWARPS=2` and + `GGML_ROCMFP4_RDNA35_NWARPS_MAX_NCOLS=2` defaults keep the single-token + microbench win and improve the guarded ROCm0 `n=2` shape: the latest serial + pass measured FAST/dual `66.56` / `58.40` us/run for `n=2`, versus the prior + `68.85` / `60.98` us/run band before extending the two-warp route. The + Qwen3.6 27B MTP guard held `33.5 tok/s` short and `27.7 tok/s` sustained, so + this is promoted as a backend micro-optimization with no sustained decode + regression. `GGML_ROCMFP4_RDNA35_NWARPS=4` was rejected because dual-scale + regressed to `57.87` us/run. The remaining 8-warp candidate was also rejected + because FAST `n=1` regressed to `59.33` us/run and failed the focused ROCm + runtime guard before multi-column checks. Extending the promoted two-warp + launch from `n=1` to `n=1..4` improved some focused multi-column ROCm + microbench rows (`dual n=2` reached `57.14` us/run), but Qwen3.6 27B MTP + sustained decode fell to `23.6 tok/s`, so the promoted upper bound stops at + `n=2`. A midpoint `GGML_ROCMFP4_RDNA35_NWARPS_MAX_NCOLS=3` build was also + checked on the Qwen3.6 35B A3B reasoning-on 262k profile; it reached + `87.5 tok/s` sustained versus `89.6 tok/s` for the same-session promoted + build, so `n=2` remains the default. +- ROCm/HIP RDNA3.5 wide-column rows-per-block now has ROCmFP4-owned compile-time + test knobs: `GGML_ROCMFP4_RDNA35_RPB_WIDE`, + `GGML_ROCMFP4_RDNA35_RPB_WIDE_DUAL`, and + `GGML_ROCMFP4_RDNA35_RPB_WIDE_FAST`. The defaults stay at `1`. A full + `RPB_WIDE=2` test improved FAST `n=8` `MUL_MAT` from `167.90` to + `131.72` us/run, but dual-scale collapsed from `148.11` to `1382.72` + us/run. A FAST-only `RPB_WIDE_FAST=2` build kept dual-scale safe + (`145.75` us/run) and improved FAST to `135.31` us/run, but Qwen3.6 + 27B MTP did not improve (`33.3 tok/s` short and `27.6 tok/s` sustained + at `n-max 4`; `n-max 5` remained burst-only at `45.5` short and `24.9` + sustained). Keep the knob off by default until a real decode guard benefits. +- ROCm/HIP RDNA3.5 `MUL_MAT_ID` routing now has a ROCmFP4-only compile-time + guard knob, `GGML_ROCMFP4_RDNA35_MMID_MAX_BATCH`, for testing whether MTP/MoE + batches should leave MMVQ earlier. The default keeps the accepted generic + RDNA3 behavior (`MMVQ_MAX_BATCH_SIZE`). A Strix test with the knob set to `1` + tied the promoted Qwen3.6 27B MTP path at `33.4 tok/s` short and `27.7 tok/s` + sustained. Follow-up threshold `2`, `3`, and `4` builds also tied at + `33.6` / `33.8` / `33.7 tok/s` short and `27.7` / `27.9` / `27.9 tok/s` + sustained. The same `3` threshold was then checked on the MoE-heavy + Qwen3.6 35B A3B MTP ROCmFP4 path and regressed to `95.8 tok/s` short and + `74.0 tok/s` sustained versus the promoted `104.4` / `89.3` band. Reusing + the older threshold `4` exploratory build on the same 35B guard measured + `104.2` / `89.2`, a near tie but still below the sustained promoted band. + No lower routing threshold is promoted. +- Target/draft "dual-stream" MTP overlap was inspected and is not a promoted + optimization. The current common MTP implementation verifies with the target + context, mirrors pre-norm embeddings into the MTP context, then drafts through + serial `llama_decode(ctx_dft, ...)` calls. ggml exposes async graph execution + and pipeline parallelism, but llama enables pipeline parallelism only for + multi-device layer-split offload cases. On single-device Strix Halo ROCm0, + target/draft overlap would require speculative scheduler changes and new + correctness guards rather than a runtime flag. The long-context optimization + focus remains KV-cache traffic, FlashAttention, memory bandwidth, and MTP + acceptance, while dual-scale ROCmFP4 mainly protects coherence. +- The MTP host loop now avoids two small sources of scheduler overhead. It + reuses a per-sequence drafting-state buffer instead of allocating a + `std::vector` on every draft call, and it tracks verify-batch sequence + bounds with one pass over token seq-ids instead of scanning every sequence for + every token. It also avoids copying all target verify rows when no previous + draft is pending, keeping only the carryover hidden row needed for the next + MTP step. The MTP path also uses a single-sequence batch append helper + instead of constructing a temporary sequence vector for each `common_batch_add` + call. It stores only non-final verify rows for partial-accept rollback, + copying the final row directly to `pending_h` for the next MTP step. It also + skips the draft-model decode call entirely when no sequence is drafting. + Debug candidate token formatting is skipped unless debug logging is enabled, + and the debug verbosity state is hoisted once per draft call instead of + rechecked inside the per-token loop. This is mainly a cleanup for + multi-sequence and long-running MTP sessions; the latest single-sequence + Qwen3.6 27B guard stayed in range at `33.7 tok/s` short and `27.9 tok/s` + sustained. +- The simple draft path also reuses an object-owned `uint8_t` drafting-state + buffer instead of allocating `std::vector` on every draft call. This + keeps both draft implementations on the same host-side allocation pattern; + the full serial gate stayed clean, with Qwen3.6 27B MTP at `33.8 tok/s` + short and `27.9 tok/s` sustained. +- The all-in-one regression harness now accepts a candidate `BUILD_DIR` and + derives separate `TEST_BACKEND_OPS_BIN` and `LLAMA_CLI_BIN` paths, so backend + microbench guards and Qwen CLI guards can run from the same candidate build. + DeepSeek remains opt-in only through `INCLUDE_DEEPSEEK_SMOKE=1`. +- ROCm/HIP vector FlashAttention now uses a ROCmFP4-only RDNA K/Q thread-group + default of `1` instead of the generic quantized-K RDNA default of `2`. This + affects only `Q4_0_ROCMFP4` and `Q4_0_ROCMFP4_FAST` K-cache cases; other + quantized FA paths keep the existing backend default. On the guarded ROCm0 + `FLASH_ATTN_EXT` shape, dual-scale improved from `122.33` to `113.03` + us/run, and FAST improved from `115.41` to `109.33` us/run. The Qwen3.6 + 27B MTP guard remained in the promoted band at `33.5 tok/s` short and + `27.6 tok/s` sustained. A wider `GGML_ROCMFP4_FATTN_KQ_NTHREADS=4` variant + was rejected because it regressed the same FA guard to `136.79` us/run + dual-scale and `124.37` us/run FAST. After the V-side default moved to `2`, + retesting `KQ_NTHREADS=2,V_NTHREADS=2` and `KQ_NTHREADS=4,V_NTHREADS=2` + still regressed the focused FA guard, so K/Q remains `1`. +- ROCm/HIP vector FlashAttention also uses a ROCmFP4-only V thread-group + default of `2`, down from the generic `D/4` path used by other quantized V + types. On the same guarded ROCm0 `FLASH_ATTN_EXT` shape, this moved + dual-scale from `113.03` to `85.63` us/run and FAST from `109.33` to + `80.74` us/run. The Qwen3.6 27B MTP guard stayed in range at `33.4 tok/s` + short and `27.6 tok/s` sustained, so this is promoted as the new default. + `GGML_ROCMFP4_FATTN_V_NTHREADS=4` also passed but was slower on the focused + FA guard; `1` was rejected because gfx1151 HIP compilation exceeded the 64 + KiB local-memory limit for ROCmFP4 FA instances. The FA guard now also + includes a Qwen3.6-style 128-head-dim, 8-KV-head, 12x-GQA ROCmFP4 shape + (`hsk=128,hsv=128,nh=8,nr23=[12,1],kv=7680,nb=1`). The accepted default + measured `246.91` us dual-scale and `219.23` us FAST on that shape. + Retesting `V_NTHREADS=4` on this wider shape produced a tiny dual-scale + improvement (`244.01` us) but regressed FAST (`224.21` us) and the existing + 64d guard, so it remains rejected. Retesting `KQ_NTHREADS=2,V_NTHREADS=2` + regressed the Qwen-style shape to `268.53` us dual-scale and `226.32` us + FAST, so K/Q remains `1`. +- ROCm/HIP vector FlashAttention now uses a ROCmFP4-owned single-half + Codebook10 expander in K/Q and V decode paths. These FA call sites already + know whether they need the low or high nibble stream, so they no longer pay + to expand both streams and discard one. The focused ROCm0 FA guard improved + from `86.13` / `81.23` us to `82.24` / `78.15` us for the 64d dual-scale / + FAST shapes, and from `247.06` / `221.19` us to `237.12` / `206.50` us for + the Qwen-style 128d shapes. The Qwen3.6 27B MTP guard held at `33.5 tok/s` + short and `27.7 tok/s` sustained in the full serial gate, so this is + promoted. +- ROCm/HIP vector FlashAttention also specializes the ROCmFP4 K/Q path when + `GGML_ROCMFP4_FATTN_KQ_NTHREADS=1`. Each thread owns the full head dot in + this promoted setting, so the kernel now expands both low/high packed + Codebook10 streams once per ROCmFP4 block and accumulates both half-blocks + together instead of loading the same packed bytes twice. The full serial gate + measured 64d FlashAttention at `81.62` / `78.13` us for dual-scale / FAST, + and the wider Qwen-style 128d guard improved from `237.12` / `206.50` us to + `228.58` / `199.32` us. Qwen3.6 27B MTP held `33.2 tok/s` short and + `27.7 tok/s` sustained, so this is promoted as a real Qwen-relevant FA + micro-optimization. + A post-specialization retest of `GGML_ROCMFP4_FATTN_V_NTHREADS=4` was + rejected. It passed the tightened FA guard and nudged the Qwen-style + dual-scale microbench to `228.33` us, but regressed 64d dual-scale to + `86.30` us and Qwen-style FAST to `201.81` us. Qwen3.6 27B MTP stayed at + `27.7 tok/s` sustained, so the promoted V-side default remains `2`. +- ROCm/HIP vector FlashAttention now uses a ROCmFP4-only V dequant rows-per- + thread default of `8`. The ROCmFP4 V helper supports 8-value chunks, and the + post-unaligned-load retest produced a real FA win: 64d dual-scale / FAST + `68.82` / `66.32` us and Qwen-style 128d dual-scale / FAST `201.13` / + `172.22` us. Qwen3.6 27B MTP held `33.5 tok/s` short and `27.7 tok/s` + sustained, so this is now promoted. It can be isolated with + `-DGGML_ROCMFP4_FATTN_V_ROWS_PER_THREAD=4` to return to the prior setting. + Retesting `GGML_ROCMFP4_FATTN_V_NTHREADS=4` on top of the 8-row default + improved only the Qwen-style dual-scale FA microbench (`187.72` us) while + regressing 64d dual-scale / FAST to `77.35` / `77.25` us and Qwen-style FAST + to `182.56` us. Qwen3.6 27B MTP tied at `33.5` / `27.7 tok/s`, so the + shipped V thread-group default remains `2`. + Retesting `GGML_ROCMFP4_FATTN_V_NTHREADS=8` on top of the 8-row default + regressed every focused FA row, including Qwen-style 128d dual-scale / FAST + at `208.94` / `200.45` us, so it was rejected without a longer MTP run. + Retesting `GGML_ROCMFP4_FATTN_KQ_NTHREADS=2` on top of the 8-row default + also regressed the focused FA guard: 64d dual-scale / FAST measured + `80.68` / `78.27` us and Qwen-style 128d measured `245.84` / `207.04` us. + Because the Qwen-style dual-scale row failed the guard, it was rejected + without a longer MTP run and K/Q remains `1`. +- ROCm/HIP vector FlashAttention now has a narrow dual-scale 128d V-thread + specialization: `GGML_ROCMFP4_FATTN_V_NTHREADS_D128_DUAL=4`. This keeps the + promoted 64d default and all FAST paths on `V_NTHREADS=2`, but uses the + previously promising 4-thread V grouping only for the Qwen-style dual-scale + 128d shape. The full serial gate measured FA at `70.37` / `66.31` us for + 64d dual-scale / FAST and `188.75` / `171.89` us for Qwen-style 128d + dual-scale / FAST, while Qwen3.6 27B MTP held `33.7 tok/s` short and + `27.9 tok/s` sustained with no KFD PIDs left running. + Retesting `GGML_ROCMFP4_FATTN_V_NTHREADS_D128_DUAL=8` was rejected. It + slightly improved the 64d dual-scale row (`69.40` us versus a same-session + `70.92` us promoted build), but regressed the Qwen-style 128d dual-scale row + from `194.40` to `211.10` us/run. Because long-context Qwen is the relevant + guard, the promoted D128 dual-scale V grouping remains `4`. + `GGML_ROCMFP4_FATTN_V_ROWS_PER_THREAD=16` was rejected during compilation: + the ROCmFP4 V dequantizer intentionally supports only `2`, `4`, and `8` + rows per thread, and the fixed-copy helper does not support the resulting + 32-byte move. The source now rejects unsupported values with a direct + ROCmFP4 compile-time error. + Retesting `GGML_ROCMFP4_FATTN_V_ROWS_PER_THREAD=2` on the promoted + D128-specialized build was rejected by the focused ROCm FlashAttention + guard. It regressed 64d dual-scale / FAST to `94.31` / `88.77` us and + Qwen-style 128d dual-scale / FAST to `270.00` / `223.88` us, so the + promoted rows-per-thread default remains `8`. +- Vulkan ROCmFP4 scale decode now uses a shared UE4M3 lookup table with + ROCmFP4's half-scale semantics. This moved the focused Vulkan dual-scale + `MUL_MAT` guard from `82.86`, `120.77`, and `181.28` us/run to `65.05`, + `83.07`, and `122.70` us/run for `n=1/2/4`. On Qwen3.6 27B MTP at 262k + context, the same change moved Vulkan sustained output from the older + `20.4 tok/s` at `--spec-draft-n-max 4` to `25.0 tok/s`; `n-max 3` now + reaches `25.3 tok/s` sustained. ROCm0 remains the promoted backend because + it still holds `33.5 tok/s` short and `27.7 tok/s` sustained. + A post-LUT Vulkan runtime sweep found a better fallback profile with q8 KV + and q8 draft KV: `--spec-draft-n-max 4` reached `34.8 tok/s` short and + `27.0 tok/s` sustained. q8 with `n-max 5` improved only the short burst + (`47.8 tok/s`) and regressed sustained output to `23.0 tok/s`; f16 KV + regressed sustained output to `22.5 tok/s`. + Follow-up isolation showed the Vulkan sustained gain comes from the main KV + cache rather than the draft KV cache: q4 main KV with q8 draft KV reached + only `34.6 tok/s` short and `25.0 tok/s` sustained, while q8 main KV with + q4 draft KV reached `34.7 tok/s` short and `26.9 tok/s` sustained. For a + Vulkan fallback, q8 main KV plus q4 draft KV is therefore the leaner near-tie + profile. Splitting q8 across only one accepted KV side was also rejected: + q8 main K with q4 main V reached `34.8 tok/s` short and `25.4 tok/s` + sustained, while q4 main K with q8 main V reached `34.6 tok/s` short and + `23.7 tok/s` sustained. The Vulkan fallback needs both accepted K and V at + q8. Adding mild acceptance filtering to the lean fallback + (`--spec-draft-p-min 0.25`) tied full q8/q8 at `27.0 tok/s` sustained while + keeping draft KV at q4; adding `--spec-draft-n-min 1`, stricter `p-min 0.75`, + and `p-split` checks stayed at `26.9 tok/s`. Retrying `n-max 5` with q8 main + KV, q4 draft KV, and + `p-min 0.25` still produced only a burst win (`47.8 tok/s` short) while + sustained output stayed at `23.0 tok/s`, so `n-max 4` remains the Vulkan + fallback setting. ROCm0 q4/q4 remains the overall promoted backend/profile. + Replacing the shared Codebook10 table with inline integer decode was tested + and rejected because it regressed the focused Vulkan FAST `n=1` guard to + `99.43` us/run. +- ROCm/HIP fallback dequant, copy, get-rows, GPU-side quantization scoring, + and standalone dequant helpers use ROCmFP4-owned HIP helpers for finite + scales and Codebook10 nibbles instead of relying on generic FP8 handling. + This keeps non-MMQ conversion paths aligned with the custom AMD format. +- A branchless HIP scalar Codebook10 nibble decoder was tested and rejected. + It passed the focused ROCm CPY, FlashAttention, and Qwen MTP guards, but + did not improve end-to-end decode. Qwen3.6 27B MTP measured `33.4 tok/s` + short and `27.7 tok/s` sustained, and the focused FlashAttention guard + slowed to `86.38` / `81.13` us for dual-scale / FAST, so the original + scalar decoder remains the default. +- CPU-side Codebook10 table decode in the quantizer/dequantizer was tested + and rejected. The full table variant failed the CPU quant guard with + dequantization at `49.04` cycles/32 for dual-scale and `84.23` cycles/32 for + FAST. The MSE-loop-only variant passed but slowed normal quantization to + `4183.33` / `4018.68` cycles/32 versus the restored arithmetic baseline at + `4034.33` / `3738.85` cycles/32, so the arithmetic CPU decoder remains the + default. +- UE4M3 scale decode in the ROCm/HIP software path uses a ROCmFP4-owned finite + scale decoder. It avoids `ldexpf`, builds normal FP32 values directly from + exponent/mantissa bits, and skips the generic FP8 NaN handling because + ROCmFP4 row validation already rejects non-finite scale bytes. +- A constant-memory HIP lookup table for the finite UE4M3 scale values was + tested and rejected. The latest isolated `GGML_ROCMFP4_USE_SCALE_LUT=1` + pass failed the focused ROCm runtime guard because FAST `n=1` regressed to + `69.48` us/run; prior checks also regressed ROCm CPY source-to-quant paths + and FlashAttention. The arithmetic finite-scale decoder remains the default. +- ROCm/HIP dequant conversion kernels use the same ROCmFP4 finite scale + decoder, keeping tensor conversion aligned with the hot MMQ/MMVQ backend + path instead of falling back to the generic FP8 helper. +- ROCm/HIP backend CPY now advertises and executes quantized + `Q4_0_ROCMFP4 -> F32` and `Q4_0_ROCMFP4_FAST -> F32` conversion paths. + This keeps diagnostic graph ops and fallback tensor conversion inside the + custom AMD decoder instead of being rejected by backend capability checks. + Contiguous q-to-f32 copies now use a ROCmFP4-specific packed-byte kernel: + one HIP thread reads one packed byte and writes the matching low/high + half-block output values. This gives coalesced output writes for normal + contiguous graph copies while the existing stride-aware block kernel remains + the fallback for views and non-contiguous tensors. +- ROCm/HIP backend CPY also supports `F16 -> Q4_0_ROCMFP4`, + `F16 -> Q4_0_ROCMFP4_FAST`, `BF16 -> Q4_0_ROCMFP4`, and + `BF16 -> Q4_0_ROCMFP4_FAST`. The kernels convert each 32-value half/bfloat + block to local FP32 and then run the same exhaustive ROCmFP4 scale search, + so runtime graph copies keep the coherence-first quantizer instead of + falling back to unsupported behavior. +- ROCm/HIP ROCmFP4 source-to-quant and quant-to-F32 CPY wrappers now use + normal multi-thread HIP launch geometry instead of launching one active + thread per quant block. This keeps F32/F16/BF16 runtime quantization and + ROCmFP4 dequantization on the same exact conversion math while removing a + launch-shape bottleneck in helper/fallback graph paths. +- ROCm/HIP ROCmFP4 quant-to-F32 CPY uses ROCmFP4-specific block dequant + helpers that decode each block scale once before unpacking all 32 values. + This avoids repeatedly decoding identical scale bytes through the generic + two-value dequant helper while preserving the same output values. For the + guarded contiguous `8192x512x2` ROCm0 CPY shape, the packed-byte path moved + dual-scale `Q4_0_ROCMFP4 -> F32` from the old `740` us/run band to + `184.48` us/run and FAST `Q4_0_ROCMFP4_FAST -> F32` to `169.99` us/run. + A split launch geometry is now used: source-to-ROCmFP4 quantization uses + 128-thread workgroups, while quant-to-F32 keeps the accepted 64-thread + packed-byte launch. A whole-path 128-thread launch was roughly tied overall + but slightly regressed quant-to-F32; isolating 128 threads to source + quantization preserves the dequant copy win while shaving the source paths. + A 256-thread launch regressed F16 source-to-quant paths and remains rejected. + After the FAST direct-value scoring win, FAST-only 256-thread and 64-thread + source launch splits were rechecked and rejected as well. The 256-thread + split regressed FAST F16 source-to-quant to `1047.24` us/run, and the + 64-thread split measured FAST F32/F16/BF16 `1055.32`, `955.35`, and + `954.78` us/run, so the shared 128-thread source launch remains promoted for + both ROCmFP4 layouts. +- ROCm/HIP contiguous quant-to-F32 CPY shared-scale staging was tested and + rejected. Decoding one block scale into shared memory and synchronizing each + 64-thread launch reduced duplicate scale decode work, but the synchronization + overhead regressed the guarded `8192x512x2` shape: dual-scale + `Q4_0_ROCMFP4 -> F32` moved from `181.84` to `188.63` us/run, and FAST + `Q4_0_ROCMFP4_FAST -> F32` moved from `170.65` to `180.03` us/run. The + direct packed-byte kernel remains promoted. +- ROCm/HIP backend CPY supports same-type packed-block copies for + `Q4_0_ROCMFP4 -> Q4_0_ROCMFP4` and + `Q4_0_ROCMFP4_FAST -> Q4_0_ROCMFP4_FAST`, including block-aligned views. + The kernel copies the packed 18-byte or 17-byte ROCmFP4 blocks directly, so + graph/view copies preserve exact bytes and avoid dequantize/requantize + fallback behavior. The launcher uses normal multi-thread HIP workgroups + rather than one-thread launches, so large packed-view copies scale with the + number of ROCmFP4 blocks. +- ROCm/HIP runtime quantization now finds the finite UE4M3 candidate nearest + `max_abs / 10` with a monotonic binary search, matching the CPU/Vulkan + reference tie behavior while avoiding the older 126-step linear nearest-scale + scan in the HIP copy utility. It also uses the same conservative lower-scale + pruning as the CPU quantizer, so runtime F32/F16/BF16-to-ROCmFP4 copies skip + smaller scales once their unavoidable clipped max-value error cannot beat the + current best exact scale. The HIP max scan uses the same plain absolute + compare as the CPU quantizer, preserving NaN/Inf handling while avoiding + `fmaxf` in the runtime quantization hot loop. +- ROCm/HIP runtime quantization specializes the exact scale search for the + only block shapes used by ROCmFP4 CPY: `0..15`, `16..31`, and `0..31`. + This keeps the same candidate order and tie behavior while letting HIP + compile the dual-scale and FAST source-to-quant paths with fixed offsets. +- ROCm/HIP dual-scale source-to-quant scoring uses a direct Codebook10 value + helper for 16-value half blocks. Final packed quantization still uses the + normal code-index helper, but scale scoring no longer has to map the selected + nibble back through the generic decode helper on the dual-scale path. +- ROCm/HIP FAST source-to-quant scoring now uses the same direct Codebook10 + value helper during scale search. This preserves the exact nearest-value + thresholds and final packed output, but avoids index-then-decode work in the + 32-value FAST scoring path. On the guarded `8192x512x2` ROCm0 CPY shape, + FAST source quantization improved from F32/F16/BF16 `1218.69`, `1138.32`, + and `1138.78` us/run to a repeat guard pass of `1047.21`, `950.93`, and + `951.00` us/run. +- ROCm/HIP `F32 -> ROCmFP4` runtime CPY stages each 32-value block into local + FP32 before running the exhaustive scale search, matching the existing + F16/BF16 source paths. This preserves exact F32 input values but avoids + rereading the global source pointer throughout scale scoring. On the guarded + `8192x512x2` ROCm0 CPY shape, dual-scale F32 source quantization improved + from roughly `9916` to `1117` us/run, and FAST improved from roughly + `10671` to `1231` us/run. +- ROCm/HIP contiguous-only source-to-quant CPY kernels for + `F32 -> ROCmFP4` were tested and rejected. They avoided the generic + multidimensional offset math, but on the guarded `8192x512x2` shape they + did not beat the existing multi-thread generic CPY path and slightly + regressed `F32 -> Q4_0_ROCMFP4_FAST`, so source-to-quant ROCmFP4 CPY keeps + the same guarded implementation for view and contiguous tensors. +- ROCm/HIP backend GET_ROWS supports both ROCmFP4 layouts. This gives pure + ROCmFP4 tensors the same direct row-gather coverage as stock small-block + quants on ROCm and keeps embedding-row access on the custom finite-scale + decoder. +- ROCm/HIP `MUL_MAT` support now covers `F16` activation tensors for both + ROCmFP4 layouts. The backend stages half activations to contiguous FP32 on + the GPU, including non-contiguous/views, then feeds the existing Q8 + activation quantizer and ROCmFP4 MMVQ/MMQ kernels. This keeps the forward + path on the AMD backend instead of rejecting the op and falling through to a + slower dequantized matrix path. The generic matmul runtime guard explicitly + allows this ROCmFP4 x F16 forward-inference case, so the support probe and + execution wrapper agree for batched activations. +- The standalone HIP dequant skeleton covers both the dual-scale and FAST + single-scale layouts, so future fused ROCm kernels can target the current + balanced FAST artifact without reintroducing the older scale path. +- The standalone HIP dequant launch now maps one thread to one packed + ROCmFP4 byte across a 256-thread global grid. This avoids the older + one-16-thread-block-per-32-values launch shape and gives future fused or + diagnostic dequant paths normal GPU occupancy scaling. +- Vulkan ROCmFP4 shaders also decode UE4M3 scales directly to the half-scale + value used by the codebook, matching CPU/HIP and avoiding repeated `* 0.5` + fixups at dequant and matmul call sites. +- Vulkan ROCmFP4 shaders keep a shared `kvalues_rocmfp4` Codebook10 table. + Arithmetic/direct Codebook10 decode variants compiled and preserved + coherence, but measured slower on Strix Halo Vulkan, so the table path + remains the active backend implementation. +- Vulkan `dequantize4()` for ROCmFP4 and ROCmFP4_FAST decodes each block's + UE4M3 scale once per 4-value vector instead of calling the 2-value helper + twice. This improves tested dual-scale ROCmFP4 small-batch matvec shapes + while keeping the promoted Vulkan runtime guard clean. +- Vulkan `Q4_0_ROCMFP4_FAST` matvec/MMQ kernels have a single-scale dot + specialization. They combine the two half-block dot sums and apply the one + FAST scale once, instead of taking the dual-scale path used by + `Q4_0_ROCMFP4`. +- Vulkan `Q4_0_ROCMFP4_FAST` MMQ stores its block scale as a scalar in + shared/register cache instead of duplicating it into a `vec2`. The focused + Strix Halo Vulkan `MUL_MAT` microbench for + `m=4096,n=1,k=14336,type_a=q4_0_rocmfp4_fast` improved from `62.18` to + `61.45` us/run. +- A Vulkan packed16 view for ROCmFP4 quant bytes was tested and rejected. It + compiled, but the focused FAST MMQ guard regressed to `83.03` us/run from the + accepted `61`-`62` us/run range, so ROCmFP4 Vulkan keeps the byte-view load + path. +- Vulkan backend CPY/SET_ROWS now has generated `F32 -> Q4_0_ROCMFP4`, + `F32 -> Q4_0_ROCMFP4_FAST`, `Q4_0_ROCMFP4 -> F32`, + `Q4_0_ROCMFP4_FAST -> F32`, and indexed SET_ROWS shaders. The SET_ROWS path + uses the same exhaustive finite UE4M3 scale search as the CPU reference, so + quantized K/V cache writes favor coherence over a cheap max-abs shortcut. +- Vulkan `F32 -> ROCmFP4` runtime quantization now uses the same exact ordered + UE4M3 scale search as CPU/HIP: find the scale nearest `max_abs / 10`, expand + outward, and stop a candidate once its partial error cannot beat the current + best scale. The candidate set is unchanged, so this avoids a slower linear + scan without falling back to a lower-quality shortcut. +- Vulkan source-to-ROCmFP4 runtime quantization now also prunes lower scale + candidates once clipping the block max alone cannot beat the current best + error. This mirrors the CPU/HIP scale search bound and keeps the candidate + set exact. The 2026-05-25 Vulkan CPY guard passed after this shader change: + F32/F16/BF16-to-dual measured `9525.39`, `2350.54`, and `2418.09` us/run, + dual-to-F32 `516.65` us/run, F32/F16/BF16-to-FAST `10111.85`, `2923.67`, + and `2949.42` us/run, and FAST-to-F32 `509.65` us/run. The full promoted + gate passed after rebuild with Qwen3.6 27B MTP at `33.9` / `28.0 tok/s` and + no KFD PIDs left running. +- Vulkan backend CPY also supports `F16 -> Q4_0_ROCMFP4`, + `F16 -> Q4_0_ROCMFP4_FAST`, `BF16 -> Q4_0_ROCMFP4`, and + `BF16 -> Q4_0_ROCMFP4_FAST`. The runtime quantization shader can load + `float`, `float16_t`, and BF16 source bits and then runs the same exact + ordered finite UE4M3 scale search. Backend tests keep a bounded NMSE + tolerance only for the half/bfloat runtime quantization cases because those + paths are inherently lossy around source-precision tie points; the + `F32 -> ROCmFP4` checks remain strict. +- Vulkan same-type CPY supports packed-block copies for + `Q4_0_ROCMFP4 -> Q4_0_ROCMFP4` and + `Q4_0_ROCMFP4_FAST -> Q4_0_ROCMFP4_FAST`, including block-aligned + non-contiguous/permuted/view copies. The non-contiguous path uses a + byte-addressed block shader and preserves exact 18-byte or 17-byte + ROCmFP4 blocks. Contiguous same-type dual-scale and FAST copies now both use + the direct byte-copy path, avoiding the generic halfword copy route for + ROCmFP4's custom 18-byte and 17-byte block layouts. +- Vulkan CPY is now covered by a dedicated regression guard so copy-path + changes cannot silently fall back or regress outside the ROCm-only CPY gate. + The guard runs same-type and source/dequant CPY correctness before measuring + the large copy performance shape, and now streams the performance phase + through `tee` so long Vulkan runs do not look idle to the command runner. + The ceilings were tightened after the lower-scale pruning gain, so the old + slow source-to-quant path no longer passes this guard. + On Strix Halo RADV Vulkan, the large guarded shape currently measures + F32/F16/BF16-to-dual at `9525.39`, `2350.54`, and `2418.09` us/run, + dual-to-F32 at `516.65` us/run, F32/F16/BF16-to-FAST at `10111.85`, + `2923.67`, and `2949.42` us/run, and FAST-to-F32 at `509.65` us/run. +- Vulkan scalar FlashAttention can now decode ROCmFP4 and ROCmFP4_FAST K/V + cache blocks. ROCmFP4 K/V is forced to the scalar FA path because the current + custom decode is not a coopmat/native matrix-core FP4 path. +- Vulkan scalar FlashAttention can use the integer-dot MMQ K path for both + ROCmFP4 K-cache layouts. The FAST layout expands each 4-bit Codebook10 value + into packed signed int8 lanes and uses its single UE4M3 scale as the K block + multiplier. The dual-scale layout also uses packed signed int8 lanes, but + splits the dot accumulation by half-block so each 16-value half uses its own + UE4M3 scale. This keeps the quality-biased STRIX K-cache path fast without + applying one scale to a two-scale block. +- Build and runtime verification generated the Vulkan SPIR-V entries for + ROCmFP4 copy/SET_ROWS shaders, linked `libggml-vulkan.so`, and passed + Vulkan ROCmFP4 CPY plus MUL_MAT smoke tests on Strix Halo. +- Row validation rejects invalid scale bytes outside finite unsigned UE4M3 + (`0x00` through `0x7e`) so corrupted custom GGUF tensors fail early. +- Quantization keeps the exhaustive 126-scale UE4M3 search for both normal and + imatrix paths. Candidate-window scale search was tested and improved GGUF + creation speed, but it regressed the Qwen3-4B short WikiText-2 PPL on the + compact FAST path, so it was rejected for coherence. +- The exhaustive scale search now visits the UE4M3 candidate nearest the + block's `max_abs / 10` first using a monotonic binary search, expands + outward, and exits a candidate scale once its partial error cannot beat the + current best scale. This remains exact because every finite scale is still + evaluated; on the Qwen3-4B FAST_COHERENT artifact it produced a + byte-identical GGUF while cutting FAST quantization cost sharply. +- CPU scale decode now uses a 127-entry finite UE4M3 half-scale table for the + exhaustive scale search and row dequantization. The table preserves the same + exact FP32 values as the former bit-construction decoder, but avoids + rebuilding them for every scale candidate. +- CPU scale search now has separate unweighted and imatrix-weighted MSE + scoring paths. The normal path avoids per-value weight branches, while the + imatrix path precomputes the row-energy calibration weight once per + 16/32-value block instead of recomputing the same `sqrtf` term for every + candidate scale. +- CPU normal quantization scans each block once for finite values and uses a + finite-only nearest-Codebook10 helper in the exhaustive MSE loop when the + block is clean. Non-finite blocks still use the guarded helper. This + promoted conversion-speed path measured focused dual-scale / FAST normal + quantization at `3844.38` / `3582.57` cycles per 32 values in the latest + guard. +- CPU imatrix-weighted scale-MSE scoring now uses the same finite-only + nearest-Codebook10 helper when the source block is finite. This preserves the + guarded path for non-finite input while improving FAST imatrix GGUF creation: + same-session pre-candidate FAST imatrix was `5258.07` cycles / 32 values, and + two guarded candidate passes measured `4448.73` and `4447.32`. Dual imatrix + stayed in the noisy guarded band, so the claim is limited to FAST imatrix. +- The weighted and unweighted exhaustive scale loops are split as well, so + the normal quantizer does not branch on imatrix state for every finite + UE4M3 candidate. This keeps the exact candidate order and tie behavior while + improving CPU GGUF creation speed for both ROCmFP4 layouts. +- The CPU quantizers fill every packed nibble byte in each ROCmFP4 block, so + they no longer clear `qs` before packing. This is an exact store cleanup: + correctness stayed clean, `q4_0_rocmfp4` quantize improved to `5244.46` + cycles / 32 values, `q4_0_rocmfp4_fast` improved to `4668.28` cycles / 32 + values. +- CPU scale selection scans block maxima with a plain absolute-value compare + instead of `fmaxf`. NaNs still do not raise the maximum, infinities are still + rejected before scale search, and finite output is unchanged. This moved + `q4_0_rocmfp4` quantize to `5228.64` cycles / 32 values and FAST to + `4516.45` cycles / 32 values. +- CPU dequantization and quantization-error scoring use the ROCmFP4 arithmetic + Codebook10 decoder, which avoids a table fetch per unpacked nibble. CPU + fallback vec-dot keeps the 16-entry codebook table because measured Strix + Halo fallback dot speed was better with the table there. This hybrid keeps + the dequant win without regressing CPU vec-dot. +- CPU fallback vec-dot now reuses each packed ROCmFP4 byte for both low and + high nibbles before table decode. This preserves exact output, moved focused + dual-scale vec-dot from `31.86` to the `29.77`-`29.82` cycles / 32 values + band, and kept FAST in the `27.04`-`27.06` cycles / 32 values band. +- Two additional CPU decode shortcuts were rechecked on 2026-05-24 and + rejected. Replacing arithmetic Codebook10 decode with table decode in + row dequantization and scale-MSE scoring slowed CPU dequantization from the + guarded `33`-cycle band to `51`-`84` cycles / 32 values. Returning a direct + decoded value during MSE scoring instead of index-then-decode also passed + correctness but regressed normal quantization in the measured guard, so the + original arithmetic decoder remains the CPU path. A narrower full-block + weighted-MSE-only retry was also rejected because it regressed the focused + FAST imatrix timing to `5007.73` cycles / 32 values. +- A direct finite-scale table helper for CPU quantizer scale-search candidates + was also rejected. It helped dual-scale normal quantization, but repeat + guard runs regressed FAST normal quantization to `4043.60` and + `4289.66` cycles / 32 values. The guarded scale helper remains in place + because the compact STRIX_LEAN preset depends heavily on FAST tensors. +- NaN-only and branchless finite-scan variants were also rejected for default. + The NaN-only scan was noisy and the same-session `isfinite()` scan measured + better dual-scale normal quantization (`3735.41` vs `3776.53` cycles / 32 + values), while the branchless boolean-and scan regressed FAST normal + quantization to `3773.44` cycles / 32 values. +- Per-value Codebook10 quantization uses exact nearest-neighbor thresholds + instead of a 16-entry scan. The hot quantizer path uses one reciprocal scale + per candidate/block and multiplies each value by that reciprocal instead of + dividing per value. On the Qwen3-4B FAST_COHERENT check this kept PPL tied + with the accepted artifact while cutting GGUF creation time further. +- CPU exhaustive scale search now prunes lower-scale candidates after the + clipped max-value error alone cannot beat the current best error. The + imatrix path uses the positive calibration weight of the max element for the + same conservative bound. This does not change accepted values because every + skipped smaller scale has a larger unavoidable clip error. The weighted path + also combines imatrix weight preparation, max-absolute scan, and max-value + pruning-weight selection into one pre-scan, while both exhaustive loops stop + once no valid lower or upper scale candidates remain. Latest 40-iteration + quant guard run: `q4_0_rocmfp4` normal `4049.28` cycles / 32 values, FAST + normal `3721.48`, imatrix dual-scale `5251.76`, imatrix FAST `4898.75`. +- Adding `GGML_RESTRICT` to the local CPU scale-scoring helper pointers was + tested and rejected. It compiled and passed the quant guard, but did not + improve normal quantization and made the imatrix guard noisier/slower in + the measured pass, so the existing helper signatures were kept. +- Regression guards: + - `scripts/check-rocmfp4-deepseek-regression.sh` is an optional compatibility + smoke guard for a second ROCmFP4-converted model family. It is not part of + the promoted-gain gate because no reproducible DeepSeek speedup has been + established yet. The default all-regression script skips it unless + `INCLUDE_DEEPSEEK_SMOKE=1` is set. + - `scripts/check-rocmfp4-qwen-mtp-regression.sh` verifies the promoted + Qwen3.6 27B MTP ROCmFP4 262k-context `draft-mtp` path. The stable guard + uses ROCm0 and `--spec-draft-n-max 4`. On ROCm0, `n-max 4` improved the + short guard prompt from `27.7` to `33.6 tok/s` versus `n-max 3`, and the + longer forced-output prompt from `25.6` to `26.3 tok/s`; the dual-scale + MMVQ VDR tune then moved the longer prompt to `27.8 tok/s`. `n-max 5` + and `n-max 6` improved only the bursty short prompt after the MMVQ tune + but regressed sustained output to `24.8` and `24.0 tok/s`, respectively. + Follow-up `n-max 5` checks with `--spec-draft-p-min 0.75`, + `--spec-draft-p-min 0.90`, and `--spec-draft-n-min 1` still held the + short prompt at `45.0`-`45.1 tok/s` but kept sustained output at only + `24.7 tok/s`, so `n-max 4` remains promoted. + The guard now checks both short and sustained prompts so high-acceptance + best-case gains do not hide sustained-output regressions. + Additional ROCm0 checks rejected larger batch sizes, smaller ubatch, + q8/f16 KV cache, `--swa-full`, `--no-host`, `--no-op-offload`, + `--no-repack`, polling changes, lower and higher CPU thread counts, + greedy sampling, backend sampling, p-split changes, sampler chain trimming, + and combined MTP+ngram speculation because none improved the sustained + prompt. After the MMVQ VDR tune, `-b 1024 -ub 512`, `-b 2048 -ub 512`, + and `-b 512 -ub 256` still tied the promoted `27.8 tok/s` sustained + result, while `-b 1024 -ub 1024` and + `--poll-batch 1 --spec-draft-poll-batch 1` stayed at `27.7 tok/s`. + q8 and f16 KV cache dropped sustained decode to `25.4` and `26.0 tok/s`. + The MTP draft loop now honors `--spec-draft-p-min`. With that cutoff active, + `n-max 4, p-min 0.75` tied the promoted path at `33.5 tok/s` short and + `27.6 tok/s` sustained, while `n-max 5` stayed burst-only at `45.0`-`45.1` + tok/s short and `24.6`-`24.7 tok/s` sustained for `p-min 0.75` and `0.90`. + Follow-up ROCm0 KV isolation confirmed this is not a draft-cache issue: + q8 main KV with q4 draft KV measured `33.5 tok/s` short and `25.3 tok/s` + sustained, q8 main K only measured `31.5` and `21.4 tok/s`, and q8 main V + only measured `31.1` and `21.9 tok/s`. The promoted ROCm0 path therefore + keeps both accepted and draft KV at q4. + `--spec-draft-p-split 0.05` and `0.20` both tied the `27.7 tok/s` + sustained guard, `-t 24 -tb 32 --spec-draft-threads 24 + --spec-draft-threads-batch 32` tied, and trimming the sampler chain to + `top_k;top_p;temperature` regressed sustained decode to `26.6 tok/s`. + Draft-only q8 KV (`SPEC_DRAFT_TYPE_K=q8_0`, + `SPEC_DRAFT_TYPE_V=q8_0`) with main KV left at q4 tied the promoted path + at `33.6 tok/s` short and `27.7 tok/s` sustained, so the leaner q4 draft + KV default remains promoted. + The heavier Qwen3.6 27B MTP `STRIX_MTP_Q6` ROCmFP4 profile was also + checked with the same ROCm0 guard. It reached `30.1 tok/s` on the short + prompt but only `21.3 tok/s` sustained, below the guard floor, so the + Q6/quality-biased profile is not promoted for throughput. + The guard script supports `SPEC_DRAFT_N_MAX`, `SPEC_DRAFT_N_MIN`, + `SPEC_DRAFT_P_MIN`, `SPEC_DRAFT_P_SPLIT`, `THREADS`, `THREADS_BATCH`, + `SPEC_DRAFT_THREADS`, `SPEC_DRAFT_THREADS_BATCH`, `SAMPLERS`, + `BATCH_SIZE`, `UBATCH_SIZE`, `CACHE_TYPE_K`, `CACHE_TYPE_V`, + `SPEC_DRAFT_TYPE_K`, `SPEC_DRAFT_TYPE_V`, `EXTRA_ARGS`, and + `SPEC_EXTRA_ARGS` environment overrides for + controlled sweeps while defaulting to the promoted `n-max 4`, `n-min 0`, + `p-min 0.0`, `p-split 0.10`, q4 KV, `-t 16`, `-tb 32`, `-b 512`, and + `-ub 512` settings. + - `scripts/check-rocmfp4-quant-regression.sh` runs quant correctness plus + CPU quantizer, dequantizer, and vec-dot cycle ceilings for both ROCmFP4 + block layouts. It checks normal and imatrix quantization, and now also + protects CPU fallback dequant/vec-dot paths so decode-helper experiments + cannot pass while slowing non-GPU fallbacks. Recent pass after keeping the + `isfinite()` finite-block scoring promotion and adding the weighted/imatrix + finite scorer: dual-scale quant `3844.38`, FAST quant `3582.57`, dual + dequant `33.59`, FAST dequant `33.13`, dual vec-dot `29.96`, FAST vec-dot + `27.03`, dual imatrix `5587.43`, and FAST imatrix `4447.32` cycles / 32 + values. + - `scripts/check-rocmfp4-vulkan-runtime-regression.sh` measures focused + Vulkan `MUL_MAT` runtime for ROCmFP4 FAST and dual-scale layouts, catching + shader regressions that can be hidden by end-to-end decode noise. The + guard covers `n=1`, `n=2`, `n=4`, and `n=8` for both layouts. Recent + tightened serial pass measured FAST `55.82`, `71.59`, `105.10`, and + `163.41` us/run for `n=1/2/4/8`, and dual-scale `64.87`, `83.24`, + `118.56`, and `194.27` us/run for `n=1/2/4/8`. The previous serial pass + after adding the shared ROCmFP4 UE4M3 + scale LUT was FAST `53.66`, `71.67`, `105.14` us/run and dual-scale + `65.05`, `83.07`, `122.70` us/run for the same shapes. + - `scripts/check-rocmfp4-vulkan-cpy-regression.sh` measures Vulkan0 CPY for + `F32/F16/BF16 -> Q4_0_ROCMFP4`, + `F32/F16/BF16 -> Q4_0_ROCMFP4_FAST`, and the matching quant-to-F32 + dequant copy paths on the same large shape used by the ROCm CPY guard. + It is included in the all-regression harness to catch accidental Vulkan + copy fallback or shader-routing regressions. + - `scripts/check-rocmfp4-rocm-runtime-regression.sh` measures the same + focused `MUL_MAT` shapes on ROCm0. The guard covers `n=1`, `n=2`, `n=4`, + and `n=8` for both FAST and dual-scale ROCmFP4 so MTP-style multi-column + regressions are caught instead of only protecting single-token matvec. + Recent tightened serial pass after extending the RDNA3.5 two-warp route + through `n=2` measured FAST `51.66`, `66.56`, `101.27`, and `168.84` + us/run for `n=1/2/4/8`, and dual-scale `53.66`, `58.40`, `87.32`, and + `148.26` us/run for `n=1/2/4/8`. The `n=8` guard was added after a + rejected wide-rows candidate regressed dual-scale `n=8` to `1382.72` + us/run. + - `scripts/check-rocmfp4-rocm-cpy-regression.sh` measures ROCm0 CPY for + `F32/F16/BF16 -> Q4_0_ROCMFP4`, + `F32/F16/BF16 -> Q4_0_ROCMFP4_FAST`, and the matching quant-to-F32 + dequant copy paths on a large `8192x512x2` shape. Recent serial-gate pass + after direct FAST value scoring: F32/F16/BF16-to-dual `1111.73`, + `1008.69`, `1006.93` us/run, dual-to-F32 `182.25` us/run, + F32/F16/BF16-to-FAST `1047.21`, `950.93`, `951.00` us/run, and + FAST-to-F32 `170.36` us/run. + - `scripts/check-rocmfp4-all-regression.sh` runs the promoted-gain gate: + quant, Vulkan runtime, Vulkan CPY, ROCm runtime, ROCm FlashAttention, + ROCm CPY, and Qwen MTP guards serially, then checks ROCm KFD PIDs. Runtime + microbenchmarks should use this serial path rather than being run in + parallel with other GPU/UMA workloads. DeepSeek is not part of this + promoted-gain gate because no reproducible DeepSeek speedup has been + established; run the separate compatibility smoke only when explicitly + needed with `INCLUDE_DEEPSEEK_SMOKE=1`. The K/Q block-pair FlashAttention + serial pass held Qwen3.6 27B MTP at `33.2 tok/s` short and `27.7 tok/s` + sustained, with no KFD PIDs left running. The same pass measured ROCm + runtime `MUL_MAT` at FAST `54.16` / `66.13` / `101.73` / `178.36` us and + dual-scale `51.65` / `57.98` / `88.33` / `148.48` us for `n=1/2/4/8`, + and ROCm FlashAttention at `81.62` / `78.13` us for 64d dual-scale / FAST + and `228.58` / `199.32` us for Qwen-style 128d dual-scale / FAST. + - The MTP `accept()` path now skips re-copying `pending_h` when acceptance + lands on the final verify row already staged by `process()`. The focused + Qwen MTP guard held `33.8 tok/s` short and `27.9 tok/s` sustained after + this host-side cleanup. + - The MTP `process()` path now stores only the non-final verify rows needed + for partial-accept rollback, while copying the final target hidden row + directly to `pending_h` for the next MTP step. The focused Qwen MTP guard + held `33.9 tok/s` short and `27.9 tok/s` sustained, and the full serial + gate held `33.7 tok/s` short and `27.9 tok/s` sustained after this cleanup. + - The simple draft and MTP draft paths now return before + `llama_decode(ctx_dft, batch)` when no sequence is actively drafting. The + focused Qwen MTP guard held `33.8 tok/s` short and `28.0 tok/s` sustained, + and the full serial gate held `33.7 tok/s` short and `27.9 tok/s` + sustained after this idle/no-draft cleanup. + - The simple draft path now uses a reusable `uint8_t` drafting-state buffer + instead of allocating `std::vector` per draft call. The focused Qwen + MTP guard held `33.7 tok/s` short and `28.0 tok/s` sustained, and the full + serial gate held `33.8 tok/s` short and `27.9 tok/s` sustained. + - The MTP draft loop now skips its debug-candidate loop entirely unless + debug logging is enabled, hoists the debug verbosity state once per draft + call, and uses direct vector indexing in the hot per-token path. The + focused Qwen MTP guard held `33.8 tok/s` short and `27.9 tok/s` sustained + after this cleanup, so it is kept as a low-risk host-side simplification + rather than claimed as a decode-speed gain. + - The simple and MTP draft paths now use a shared direct one-sequence batch + append helper instead of `common_batch_add(..., { seq_id }, ...)` in the + hot speculative path. This avoids a temporary sequence-id container without + changing multi-sequence batch behavior elsewhere. The focused Qwen MTP + guard held `33.9 tok/s` short and `27.9 tok/s` sustained, and the full + serial gate held `33.8 tok/s` short and `27.9 tok/s` sustained. + - The MTP verify-row buffer now reserves for the configured draft depth and + only grows when needed instead of shrinking/resizing on every verification + pass. The focused Qwen MTP guard held `33.8 tok/s` short and `27.9 tok/s` + sustained, and the full serial gate held `33.9 tok/s` short and + `27.9 tok/s` sustained with no KFD PIDs left running. + - The MTP `process()` path now copies retained verification hidden rows from + the target embedding buffer in one contiguous `memcpy()` instead of one + `llama_get_embeddings_pre_norm_ith()` plus `memcpy()` per row. Rollback + behavior is unchanged. The focused Qwen3.6 27B MTP guard held + `33.7 tok/s` short and `27.9 tok/s` sustained, and the 35B A3B guard held + `104.1 tok/s` short and `89.2 tok/s` sustained. The same build later + passed the full serial all-regression gate with `INCLUDE_QWEN35_A3B_GUARD=1`, + including Qwen3.6 27B MTP at `33.8` / `27.9 tok/s` and Qwen3.6 35B A3B MTP + at `104.1` / `89.3 tok/s`. + - A matching contiguous-pointer cleanup inside the MTP `draft()` loop was + tested and rejected. It replaced per-row + `llama_get_embeddings_pre_norm_ith(ctx_dft, i_batch)` calls with one + `llama_get_embeddings_pre_norm(ctx_dft)` pointer per draft decode + iteration. The 27B MTP guard held at `33.8` / `27.9 tok/s`, but the 35B A3B + repeat measured `104.3` / `88.7` and `104.3` / `89.2 tok/s`, below the + promoted `89.3 tok/s` sustained band, so the code change was removed. + - A single-sequence MTP `draft()` fast path was tested and rejected on + 2026-05-25. It removed the active-sequence bookkeeping loop for the common + `n_seq == 1` case and passed the dense 27B guard at `33.7` / `28.0 tok/s`, + but the 35B A3B sustained guard collapsed to `25.7 tok/s` despite a + passing `103.1 tok/s` short check. Reverting that path restored the 35B A3B + guard to `104.3` / `90.3 tok/s`, so the shared multi-sequence draft loop + remains the promoted implementation. + - A dual-scale-only finite-pack CPU quantizer shortcut was tested and + rejected on 2026-05-24. It passed correctness, but even after isolating + the shared scale chooser it regressed the protected FAST quant path + (`q4_0_rocmfp4_fast` normal quant rose into the `3882`-`4022` cycles / 32 + values band versus the clean `3623` cycles / 32 values baseline). The + final packing loops therefore remain on the guarded nearest-code helper. +- The Strix ROCmFP4 build script now builds the quant regression test + binaries (`test-quantize-fns`, `test-quantize-perf`, and + `test-backend-ops`) alongside `llama-cli`, `llama-quantize`, and + `llama-bench`, so quant and runtime guards work from a clean build + directory. +- `test-quantize-perf --imatrix` benchmarks the ROCmFP4 quality/coherence + path through `ggml_quantize_chunk(..., imatrix)` with synthetic importance + weights. The quant regression guard includes this mode to reject imatrix-side + CPU changes that would not show up in the normal non-imatrix timing. + +High-upside Strix-specific work: +- The next significant speed step is likely a fused ROCmFP4 decode-and-dot + ROCm matvec path. The current ROCmFP4 wins come from compact blocks and + avoiding generic decode/copy overhead; a fused path would keep Codebook10 + values and UE4M3 scales in registers/shared memory through the dot product + instead of materializing wider intermediates. +- A ROCmFP4-aware long-context attention path is the second major target. The + long-context limit is mostly KV traffic, FlashAttention shape efficiency, and + memory bandwidth. The current dual-scale layout protects coherence, but it is + not itself a large speed lever unless the attention kernels consume it + directly and efficiently. +- MTP target/draft overlap is a possible scheduler project, not a flag. The + current common MTP flow is serial on one Strix Halo ROCm device. Real overlap + would need scheduler changes plus acceptance/correctness guards, and it + should only be promoted if it beats the sustained Qwen 262k guard. +- Coherence should stay protected by tensor-aware ROCmFP4 profiles: dual-scale + for sensitive tensors and FAST only where guarded model tests show no + sustained decode or quality regression. Pure speed-only profiles are not + promoted in this tree without the serial regression gate. + +Hardware note: +- This is a special AMD-targeted ggml/llama.cpp quantization and backend + path. It includes custom Vulkan and ROCm/HIP handling for the new GGUF + types, but it is not yet a native rocWMMA FP4 tensor-core implementation. + Current speed gains come from the compact block layout and backend decode + paths; deeper rocWMMA/cooperative-matrix work is future optimization work. +- NVIDIA CUDA is disabled in the Strix-FP4 build (`-DGGML_CUDA=OFF`). Some + upstream llama.cpp HIP backend sources still live under + `ggml/src/ggml-cuda` and are compiled by HIP for AMD, but the ROCmFP4-owned + helper code and user-facing build/run path are ROCm/HIP/Vulkan targeted. + This tree also accepts `GGML_HIP_ENABLE_UNIFIED_MEMORY=1` as the AMD-named + alias for the upstream unified-memory switch. +- The bundled rocWMMA 7.1.0 headers expose gfx12 WMMA paths for FP8/BF8 and + integer 8-bit inputs, but no native FP4 input type or FP4 WMMA/MFMA builtin + is visible locally. A true matrix-core ROCmFP4 path therefore needs a + measured unpack/convert strategy first, such as ROCmFP4 Codebook10 to int8 + WMMA or FP8 WMMA tiles, before claiming native FP4 tensor-core execution. +- rocWMMA FlashAttention is intentionally opt-in via + `GGML_HIP_ROCWMMA_FATTN=ON scripts/build-strix-rocmfp4-mtp.sh`. + It currently compiles with the local rocWMMA headers in + `/path/to/third_party/rocWMMA`, but the Strix Halo benchmark + regressed sustained Qwen MTP decode (`23.3 tok/s` vs the promoted + `26.2 tok/s` default HIP FlashAttention path), so the default build keeps it + disabled. A follow-up on the 35B A3B ROCmFP4 MTP guard measured only + `99.7` / `76.1 tok/s` versus the promoted `104.4` / `89.3` band, so this + remains true for the MoE-heavy profile as well. +- TurboQuant and TriAttention are not present as runtime flags in this isolated + tree. Integrating them would require a source-level merge into `strix-fp4`; + do not claim support or promote them unless they beat the serial ROCmFP4 + regression gate. diff --git a/ggml/rocmfp4/rocmfp4.c b/ggml/rocmfp4/rocmfp4.c new file mode 100644 index 000000000000..bccefcec15da --- /dev/null +++ b/ggml/rocmfp4/rocmfp4.c @@ -0,0 +1,797 @@ +#define GGML_COMMON_DECL_C +#include "../src/ggml-common.h" + +#include "rocmfp4.h" + +#include +#include +#include + +// ggml-base is compiled architecture-neutral (no -mavx2), so SIMD for the hot +// CPU dot product is enabled per-function via a target attribute plus a runtime +// CPU check.

The promoted ROCmFP4 implementation remains the template for how the +family should behave in llama.cpp: + +- Keep 32-weight blocks so CPU, HIP, and Vulkan kernels can reuse the same + Q4/Q8-style reduction shape and GGUF row-size assumptions. +- Use finite unsigned UE4M3 scale bytes only. `0x7f` and sign-bit scale bytes + are invalid, matching the ROCmFP4 validation rule. +- Prefer reconstruction-MSE scale selection over plain max-abs scaling. ROCmFP4 + searches each 16-weight half-block; ROCmFP3 and ROCmFP6 follow the same + half-block policy, while ROCmFP8 currently uses one full-block scale. +- Preserve the ROCmFP4 kernel contract: CPU reference quant/dequant/dot first, + then HIP/Vulkan `CPY`, `GET_ROWS`, `SET_ROWS`, `MUL_MAT`, and `MUL_MAT_ID` + paths, with backend-op coverage before claiming runtime support. +- Keep dequant math explicit and deterministic: integer code times decoded + UE4M3 scale. ROCmFP4 uses the Codebook10 half-scale table; ROCmFPX formats + use their own integer code ranges but must retain the same finite-scale and + integer-dot discipline. + +The ROCmFP4 Codebook10 levels are not reused by FP3/FP6/FP8 directly: +`ROCmFP3` uses `0, +/-1, +/-2, +/-4`, `ROCmFP6` uses signed-magnitude levels up +to `31`, and `ROCmFP8` uses signed int8 levels clamped to `[-127, 127]`. +What is inherited is the block/scale/kernel/dequant contract. + +Current status (June 16, 2026): +- CPU reference quantize/dequantize exists for all three formats. +- `Q3_0_ROCMFPX`, `Q6_0_ROCMFPX`, and `Q8_0_ROCMFPX` are registered as + experimental GGUF tensor types. +- ROCm/HIP and Vulkan kernels support `CPY`, `GET_ROWS`, `SET_ROWS`, and + `MUL_MAT`/`MUL_MAT_ID` for all three formats. +- Qwen3-0.6B BF16 smoke tests pass on CPU, ROCm0, and Vulkan0. +- Generic baseline quant presets now include lean coherency routing.

The activations are quantized to q8_1 and the weight codes decoded to int8, so the dot product runs on dotPacked4x8EXT with the UE4M3 scales factored out of the inner loop. mul_mat_vecq (decode): Q4_0_ROCMFP4, Q4_0_ROCMFP4_FAST, Q8_0_ROCMFPX mul_mmq (prefill): Q4_0_ROCMFP4, Q4_0_ROCMFP4_FAST Q4_0_ROCMFP4 carries two UE4M3 scales per 32-element block, so its low and high nibbles cannot share an int32 accumulator. Both the mat-vec and the matmul path keep separate accumulators for the two halves and apply the scales independently; the single-scale _FAST variant uses one accumulator. fp3 and fp6 are left on the float path for now: fp3 needs a bit-window gather that does not fit the current cache_b layout, and the fork's fp6 integer path assumes the unpacked block layout that this tree already corrects. Measured on Radeon 8060S (RADV STRIX_HALO), FastContext-4B ROCmFP4, interleaved runs on an idle GPU: batched decode b=1 +0.6% b=8 +4.6% (b=2/4 within noise) tg128 81.0 -> 82.4 t/s pp512 no change MMQ for prefill is neutral on this device, but a control run with stock q8_0 (which has had MMQ upstream all along) behaves the same way, so this is the coopmat matmul already winning on Strix Halo rather than anything specific to these types. The path is kept because it should help devices without coopmat. test-backend-ops passes in full both with the default heuristic and with GGML_VK_FORCE_MMVQ=1: 857 ROCmFPx cases, no failures.

Each MMVQ call handled a quarter of a block and re-decoded both UE4M3 scales every time. A whole block per call amortises them 4x and lets the eight B dwords load as two dwordx4 instead of two scattered dwords. dequant_funcs.glsl: dequantize4 for fp6 and fp3 gathered each weight through its own bit window with a branch, and did one scale-table lookup per weight. Every caller passes iqs % 4 == 0, so four codes are three whole bytes (fp6) or twelve bits inside two (fp3) and all four share one scale. The branch was also stopping the decode being hoisted out of the NUM_COLS loop, which is why the old cost scaled linearly with batch size. fp6 matters for an "FP4" model because the GGUFs are mixed: the 27B carries output.weight as Q6_0_ROCMFPX, ~22 ms/step at batch 4 on its own.

Budget them by width instead: q3_0_rocmfpx with the other 3-bit types, q2_0_rocmfpx with q2_0. The measured errors are in family for their widths - q2_0_rocmfpx (0.004768 quant / 0.059435 dot) is better than q2_0 (0.008672 / 0.140697) and tq2_0 (0.008681 / 0.141345), which already pass. Reference implementation error is 0.000000 for both, and test-backend-ops MUL_MAT on CPU passes 11/11 cases for each, so the vec_dot path is fine.

Add dequantize_row_ wrappers in ggml-quants for the six types so the test exercises them like any other quant. Python side: add dequantizers for Q4_0_ROCMFP4, Q4_0_ROCMFP4_FAST and Q2_0_ROCMFPX, which had none, and fix Q6_0_ROCMFPX, which decoded code 32 (sign bit set, zero magnitude) as -0 where the C codec yields -32.

K-only and V-only q8 main KV regressed to - `70.5` and `74.6` sustained, so both accepted K and V need q8 and the draft - KV can stay q4. The updated default 35B guard then passed at `103.3 tok/s` - short and `90.1 tok/s` sustained. - Sampler-chain trims and backend sampling did not beat the promoted sustained - profile: `top_k;top_p;temperature` reached `104.2` / `87.5`, the milder - `penalties;top_k;top_p;min_p;temperature` chain reached `104.1` / `88.9`, - and `--backend-sampling` reached `104.3` / `89.2`, so the default sampler - path stays promoted. - A single-sequence MTP `process()` fast path for `-np 1` was also prototyped, - built, and rejected because the guard dropped to `104.1 tok/s` short and - `88.5 tok/s` sustained; the change was removed. - MoE `rows_per_block` compile-time variants were checked against the same 35B - guard and also rejected: `rows_per_block=4` measured `103.8` short / - `89.1 tok/s` sustained, `rows_per_block=3` measured `86.8 tok/s` sustained, - and `rows_per_block=1` measured `103.6` / `88.7 tok/s`, none beating the - promoted `104.3` / `89.3` band. - The Pi server profile was also started and stopped successfully with - `n_ctx = 262144`, `draft-mtp` initialized, built-in tools enabled, and - `thinking = 1`; ROCm reported no KFD PIDs after shutdown. The promoted - profile is now covered by the focused - `scripts/check-rocmfp4-qwen35-a3b-mtp-regression.sh` guard, which defaults - to `n-max 3`, q8 main KV, q4 draft KV, and `p-min 0.25` with `100.0` short - and `85.0 tok/s` sustained floors. - Follow-up `p-min 0.25/0.50/0.75`, `p-split 0.05/0.20`, and `n-min 1` - checks on the q4-KV baseline all tied the same `80.5`-`80.8 tok/s` sustained - band, while `p-min 0.25` on the q8-main/q4-draft path tied at `85.4 tok/s` - sustained, so the - conservative `n-min 0`, `p-min 0.0`, `p-split 0.10` defaults remained - promoted until the MTP internal sampler was changed from `top_k=1` to - `top_k=10`, making the `p-min` cutoff operate on a meaningful candidate - distribution while the draft loop still selects the top sorted candidate. - A pre-change p-min sweep on the actual promoted `n-max 3`, q8-main/q4-draft - profile measured `104.2` / `89.1` at `p-min 0.25`, `104.1` / `89.0` at - `0.50`, `104.0` / `89.3` at `0.75`, and `104.2` / `89.1` at `0.90`. - Follow-up p-split checks measured `103.7` / `88.9` at `0.05` and - `103.8` / `89.3` at `0.20`; n-min checks measured `103.8` / `88.9` for - `1` and `104.2` / `89.2` for `2`. None beat the promoted - sustained-plus-short profile. Combined `p-min`/`p-split` follow-ups also - tied rather than beat the default: `p-min 0.25` with `p-split 0.30` - repeated at `104.6` / `89.5`, `p-split 0.40` and `0.50` measured - `104.6` / `89.5` and `104.4` / `89.5`, and `p-split 0.70` / `0.90` - measured `104.8` / `89.5` and `104.7` / `89.5`; the same-session default - tied at `104.7` / `89.5`. With `top_k=10`, the 35B A3B profile now promotes - `--spec-draft-p-min 0.25`: default `p-min 0.0` measured `104.3` / `89.3`, - while `p-min 0.25` measured `103.9` / `90.0` after a first sustained run at - `89.8 tok/s`. The dense 27B profile should stay at `p-min 0.0`; the same - `p-min 0.25` filter regressed it to `24.6 tok/s` sustained. The full - all-regression harness can include the 35B guard with - `INCLUDE_QWEN35_A3B_GUARD=1`. - The MTP draft sampler now uses a probability-only top-10 helper for this - path. The draft loop only consumes the sorted top candidate and its - probability, so skipping the unused final RNG sampler selection preserved the - output path while improving the 35B A3B guard to `104.6 tok/s` short and - `90.2 tok/s` sustained. The dense 27B guard remained stable at `33.9` / - `28.1 tok/s`. - A fixed insertion top-10 replacement for `std::partial_sort` was tested and - rejected after the 35B A3B short guard dropped to `73.0 tok/s`, below the - `100.0 tok/s` floor. A `std::nth_element` plus top-k slice sort variant was - also rejected after the same guard dropped to `71.5 tok/s`. - Narrowing the MTP top-k probability accumulator from `double` to `float` was - also rejected: dense 27B still passed at `34.0` / `28.1 tok/s`, but the 35B - A3B short guard repeated below floor at `84.1` then `93.4 tok/s`; restoring - the `double` accumulator recovered the short guard to `104.4 tok/s`. - A `std::partial_sort_copy` top-k buffer variant built and passed the same - guard at `104.4 tok/s` short and `90.2 tok/s` sustained, but a same-session - promoted-build comparison measured `104.1` / `90.2`, so it was not promoted: - it added sampler buffer/clone complexity without a sustained decode gain. - Jackrong Qwopus3.6 27B v2 MTP BF16 was converted to STRIX_LEAN ROCmFP4 at - `4.34 BPW`. At native `262144` context with reasoning on, q4 main/draft KV, - and `n-max 4`, ROCm0 initially measured `34.9` / `29.6 tok/s`; increasing - only the batch to `-b 1024 -ub 512` moved sustained decode to `29.9 tok/s`. - Follow-up batch shapes `1280/512`, `1536/512`, and `1536/768` measured - `29.8`, `29.9`, and `29.8 tok/s` sustained respectively, so the smaller - `1024/512` profile remains promoted. Light acceptance filters `p-min 0.05` - and `0.10` also tied at `29.9 tok/s` sustained without beating the default. - Lower draft-depth checks with the same promoted batch rejected `n-max 1`, - `2`, and `3`, which measured only `19.9`, `26.6`, and `27.3 tok/s` - sustained. Qwopus therefore stays on `n-max 4`, unlike the 35B A3B profile - where `n-max 3` plus q8 main KV is best. - `--backend-sampling` tied sustained decode at `29.9 tok/s` but lowered prompt - throughput, so it is not promoted. Thread split checks at target/draft - `12/32` and `24/32` also tied `29.9 tok/s` sustained; the simpler default - `16/32` thread shape remains the recommended Qwopus profile. - KV isolation confirmed this is not like the 35B A3B q8-main profile: - draft-only q8 KV measured `35.1` / `29.8 tok/s`, and full q8 main plus q8 - draft KV measured `36.6` / `26.0 tok/s`. The full-q8 path improves burst - only and regresses sustained decode. Split accepted-KV checks also regressed: - q8 K only measured `35.7` / `22.3 tok/s`, and q8 V only measured `34.2` / - `24.7 tok/s`. Qwopus therefore keeps q4 main and q4 draft KV. - Vulkan0 measured `40.0` / `27.7 tok/s`, with Vulkan `n-max 3` and `n-max 5` - slower sustained; Vulkan `-b 1024 -ub 512` repeated the same `27.7 tok/s` - sustained band. q8 main KV regressed this model on both ROCm0 and Vulkan0. - A normal-path shortcut that only normalized `data[0].p` and filled the rest - of the top-k probabilities only for debug logging was rejected after the - 35B A3B short guard fell to `92.7 tok/s`, below the `100.0 tok/s` floor. - Disabling internal sampler timing with `sparams.no_perf = true` was also - tested and rejected after the same short guard dropped to `96.2 tok/s`. - Skipping the per-draft `common_sampler_reset()` in the MTP path was rejected - after the 35B A3B short guard dropped to `68.3 tok/s`; that reset remains - required to preserve the expected sampler/logit state for this helper. - A small MTP host-path cleanup now delays `llama_get_embeddings_pre_norm_ith()` - until the draft loop has confirmed that another draft token will be queued. - This avoids unused embedding-row pointer fetches on p-min rejects and final - `n-max` draft tokens. It passed the dense 27B guard at `34.0` / `28.1 tok/s`, - the 35B A3B guard at `104.4` / `90.1 tok/s`, and the Qwopus best ROCm0 - profile at `35.0` / `29.8 tok/s`. The default all-regression gate also - passed after this cleanup and ended with no KFD PIDs running. The 2026-05-25 - serial pass measured Qwen3.6 27B MTP at `33.9` / `27.9 tok/s`, ROCm runtime - FAST `45.66` / `57.81` / `88.27` / `155.05` us and dual-scale `49.16` / - `51.58` / `83.34` / `151.42` us for `n=1/2/4/8`, ROCm FlashAttention - `70.86` / `66.51` us for 64d dual-scale / FAST and `189.45` / `172.73` us - for Qwen-style 128d dual-scale / FAST, and ROCm CPY source-to-dual - `1106.89` / `1008.56` / `1006.60` us with source-to-FAST `1050.49` / - `958.98` / `950.50` us for F32/F16/BF16. - A second attempt to skip the final `n-max` `common_sampler_accept()` call was - rejected: the 35B A3B short check still reached `104.5 tok/s`, but sustained - decode fell to `81.1 tok/s`, below the `85.0 tok/s` floor. Reverting only - that sampler-accept change recovered the guard to `104.3` / `90.0 tok/s`. - Retesting the internal MTP sampler candidate count on the 35B A3B - reasoning-on profile rejected both directions around the promoted `top_k=10` - setting: `top_k=5` fell to `77.3 tok/s` sustained and `top_k=20` fell to - `69.6 tok/s` sustained. -- Reasoning-off checks on the final 35B q8-main/q4-draft profile are a - separate lower-throughput mode. `n-max 1/2/3/4` measured `77.7` / `73.9`, - `90.3` / `75.5`, `100.3` / `71.9`, and `85.7` / `66.1` short/sustained - tok/s respectively. If reasoning is disabled, `n-max 2` is currently the - best sustained profile in this bracket; the promoted fastest profile remains - reasoning-on `n-max 3`. -- Draft-thread-only checks on the promoted 35B profile also tied below the - promoted band. Keeping target threads at `16/32`, draft `8/16`, `16/16`, - and `24/32` all measured around `104.1`-`104.2 tok/s` short and - `89.1 tok/s` sustained, so the default matching draft thread counts remain. -- ROCm/HIP single-token MMVQ uses a full-block vector-dot ratio for the - dual-scale layout (`VDR_ROCMFP4_Q8_1_MMVQ=4`) while keeping the FAST layout - on the previous half-block ratio (`VDR_ROCMFP4_FAST_Q8_1_MMVQ=2`). This - lets dual-scale ROCmFP4 consume one full 32-value block per vector-dot call - without slowing the FAST dense-tensor path used by STRIX_LEAN. The focused - ROCm0 `MUL_MAT` guard improved dual-scale from the prior `78.81` us/run - serial pass to `54.89` us/run, and the Qwen3.6 27B MTP sustained guard - improved from `26.2` to `27.8 tok/s`. A broader version that also moved - FAST to `vdr=4` was rejected because sustained Qwen MTP dropped to - `24.2 tok/s`. A later FAST-only retest after the packed-byte load improved - the focused FAST ROCm guard to `41.37`, `49.29`, `80.91`, and `139.58` - us for `n=1/2/4/8`, but was still rejected because sustained Qwen MTP - dropped to `24.7 tok/s`. The remaining narrower FAST setting, - `GGML_ROCMFP4_FAST_Q8_1_MMVQ_VDR=1`, was also rejected after it failed the - focused FAST ROCm `n=1` guard at `60.18` us/run. The knob now rejects - invalid FAST MMVQ values at compile time; only `1`, `2`, and `4` are valid. -- A direct ROCmFP4 `vec_dot_q_cuda_dispatch` wrapper was tested in the - MMVQ kernels to bypass the generic constexpr function pointer call. It built - and passed the focused ROCm guard, measuring FAST `45.16` / `57.52` / - `89.44` / `156.49` us and dual-scale `50.83` / `51.11` / `84.51` / - `143.27` us for `n=1/2/4/8`, but Qwen3.6 27B MTP only reached `33.7 tok/s` - short and `27.9 tok/s` sustained. Because it did not beat the promoted - sustained band, the code change was removed. -- ROCm/HIP batched MMQ keeps the upstream-style `vdr=8` default for both - ROCmFP4 layouts, with ROCmFP4-owned compile-time test knobs - `GGML_ROCMFP4_Q8_1_MMQ_VDR` and `GGML_ROCMFP4_FAST_Q8_1_MMQ_VDR`. - FAST-only `vdr=4`, FAST-only `vdr=16`, and dual-scale `vdr=16` were tested - against the Qwen3.6 27B STRIX_LEAN ROCmFP4 bench and did not improve decode; - the tested runs all stayed at `13.56 tok/s` generation, while dual-scale - `vdr=16` slightly reduced prompt throughput. The default remains `8`. -- ROCm/HIP RDNA3.5 small-batch MMVQ now uses a ROCmFP4-specific two-warp - launch geometry for the ROCmFP4 layouts through `n=2`. Strix Halo previously - inherited the older RDNA2 one-warp table for this path. The promoted - `GGML_ROCMFP4_RDNA35_NWARPS=2` and - `GGML_ROCMFP4_RDNA35_NWARPS_MAX_NCOLS=2` defaults keep the single-token - microbench win and improve the guarded ROCm0 `n=2` shape: the latest serial - pass measured FAST/dual `66.56` / `58.40` us/run for `n=2`, versus the prior - `68.85` / `60.98` us/run band before extending the two-warp route. The - Qwen3.6 27B MTP guard held `33.5 tok/s` short and `27.7 tok/s` sustained, so - this is promoted as a backend micro-optimization with no sustained decode - regression. `GGML_ROCMFP4_RDNA35_NWARPS=4` was rejected because dual-scale - regressed to `57.87` us/run. The remaining 8-warp candidate was also rejected - because FAST `n=1` regressed to `59.33` us/run and failed the focused ROCm - runtime guard before multi-column checks. Extending the promoted two-warp - launch from `n=1` to `n=1..4` improved some focused multi-column ROCm - microbench rows (`dual n=2` reached `57.14` us/run), but Qwen3.6 27B MTP - sustained decode fell to `23.6 tok/s`, so the promoted upper bound stops at - `n=2`. A midpoint `GGML_ROCMFP4_RDNA35_NWARPS_MAX_NCOLS=3` build was also - checked on the Qwen3.6 35B A3B reasoning-on 262k profile; it reached - `87.5 tok/s` sustained versus `89.6 tok/s` for the same-session promoted - build, so `n=2` remains the default. -- ROCm/HIP RDNA3.5 wide-column rows-per-block now has ROCmFP4-owned compile-time - test knobs: `GGML_ROCMFP4_RDNA35_RPB_WIDE`, - `GGML_ROCMFP4_RDNA35_RPB_WIDE_DUAL`, and - `GGML_ROCMFP4_RDNA35_RPB_WIDE_FAST`. The defaults stay at `1`. A full - `RPB_WIDE=2` test improved FAST `n=8` `MUL_MAT` from `167.90` to - `131.72` us/run, but dual-scale collapsed from `148.11` to `1382.72` - us/run. A FAST-only `RPB_WIDE_FAST=2` build kept dual-scale safe - (`145.75` us/run) and improved FAST to `135.31` us/run, but Qwen3.6 - 27B MTP did not improve (`33.3 tok/s` short and `27.6 tok/s` sustained - at `n-max 4`; `n-max 5` remained burst-only at `45.5` short and `24.9` - sustained). Keep the knob off by default until a real decode guard benefits. -- ROCm/HIP RDNA3.5 `MUL_MAT_ID` routing now has a ROCmFP4-only compile-time - guard knob, `GGML_ROCMFP4_RDNA35_MMID_MAX_BATCH`, for testing whether MTP/MoE - batches should leave MMVQ earlier. The default keeps the accepted generic - RDNA3 behavior (`MMVQ_MAX_BATCH_SIZE`). A Strix test with the knob set to `1` - tied the promoted Qwen3.6 27B MTP path at `33.4 tok/s` short and `27.7 tok/s` - sustained. Follow-up threshold `2`, `3`, and `4` builds also tied at - `33.6` / `33.8` / `33.7 tok/s` short and `27.7` / `27.9` / `27.9 tok/s` - sustained. The same `3` threshold was then checked on the MoE-heavy - Qwen3.6 35B A3B MTP ROCmFP4 path and regressed to `95.8 tok/s` short and - `74.0 tok/s` sustained versus the promoted `104.4` / `89.3` band. Reusing - the older threshold `4` exploratory build on the same 35B guard measured - `104.2` / `89.2`, a near tie but still below the sustained promoted band. - No lower routing threshold is promoted. -- Target/draft "dual-stream" MTP overlap was inspected and is not a promoted - optimization. The current common MTP implementation verifies with the target - context, mirrors pre-norm embeddings into the MTP context, then drafts through - serial `llama_decode(ctx_dft, ...)` calls. ggml exposes async graph execution - and pipeline parallelism, but llama enables pipeline parallelism only for - multi-device layer-split offload cases. On single-device Strix Halo ROCm0, - target/draft overlap would require speculative scheduler changes and new - correctness guards rather than a runtime flag. The long-context optimization - focus remains KV-cache traffic, FlashAttention, memory bandwidth, and MTP - acceptance, while dual-scale ROCmFP4 mainly protects coherence. -- The MTP host loop now avoids two small sources of scheduler overhead. It - reuses a per-sequence drafting-state buffer instead of allocating a - `std::vector` on every draft call, and it tracks verify-batch sequence - bounds with one pass over token seq-ids instead of scanning every sequence for - every token. It also avoids copying all target verify rows when no previous - draft is pending, keeping only the carryover hidden row needed for the next - MTP step. The MTP path also uses a single-sequence batch append helper - instead of constructing a temporary sequence vector for each `common_batch_add` - call. It stores only non-final verify rows for partial-accept rollback, - copying the final row directly to `pending_h` for the next MTP step. It also - skips the draft-model decode call entirely when no sequence is drafting. - Debug candidate token formatting is skipped unless debug logging is enabled, - and the debug verbosity state is hoisted once per draft call instead of - rechecked inside the per-token loop. This is mainly a cleanup for - multi-sequence and long-running MTP sessions; the latest single-sequence - Qwen3.6 27B guard stayed in range at `33.7 tok/s` short and `27.9 tok/s` - sustained. -- The simple draft path also reuses an object-owned `uint8_t` drafting-state - buffer instead of allocating `std::vector` on every draft call. This - keeps both draft implementations on the same host-side allocation pattern; - the full serial gate stayed clean, with Qwen3.6 27B MTP at `33.8 tok/s` - short and `27.9 tok/s` sustained. -- The all-in-one regression harness now accepts a candidate `BUILD_DIR` and - derives separate `TEST_BACKEND_OPS_BIN` and `LLAMA_CLI_BIN` paths, so backend - microbench guards and Qwen CLI guards can run from the same candidate build. - DeepSeek remains opt-in only through `INCLUDE_DEEPSEEK_SMOKE=1`. -- ROCm/HIP vector FlashAttention now uses a ROCmFP4-only RDNA K/Q thread-group - default of `1` instead of the generic quantized-K RDNA default of `2`. This - affects only `Q4_0_ROCMFP4` and `Q4_0_ROCMFP4_FAST` K-cache cases; other - quantized FA paths keep the existing backend default. On the guarded ROCm0 - `FLASH_ATTN_EXT` shape, dual-scale improved from `122.33` to `113.03` - us/run, and FAST improved from `115.41` to `109.33` us/run. The Qwen3.6 - 27B MTP guard remained in the promoted band at `33.5 tok/s` short and - `27.6 tok/s` sustained. A wider `GGML_ROCMFP4_FATTN_KQ_NTHREADS=4` variant - was rejected because it regressed the same FA guard to `136.79` us/run - dual-scale and `124.37` us/run FAST. After the V-side default moved to `2`, - retesting `KQ_NTHREADS=2,V_NTHREADS=2` and `KQ_NTHREADS=4,V_NTHREADS=2` - still regressed the focused FA guard, so K/Q remains `1`. -- ROCm/HIP vector FlashAttention also uses a ROCmFP4-only V thread-group - default of `2`, down from the generic `D/4` path used by other quantized V - types. On the same guarded ROCm0 `FLASH_ATTN_EXT` shape, this moved - dual-scale from `113.03` to `85.63` us/run and FAST from `109.33` to - `80.74` us/run. The Qwen3.6 27B MTP guard stayed in range at `33.4 tok/s` - short and `27.6 tok/s` sustained, so this is promoted as the new default. - `GGML_ROCMFP4_FATTN_V_NTHREADS=4` also passed but was slower on the focused - FA guard; `1` was rejected because gfx1151 HIP compilation exceeded the 64 - KiB local-memory limit for ROCmFP4 FA instances. The FA guard now also - includes a Qwen3.6-style 128-head-dim, 8-KV-head, 12x-GQA ROCmFP4 shape - (`hsk=128,hsv=128,nh=8,nr23=[12,1],kv=7680,nb=1`). The accepted default - measured `246.91` us dual-scale and `219.23` us FAST on that shape. - Retesting `V_NTHREADS=4` on this wider shape produced a tiny dual-scale - improvement (`244.01` us) but regressed FAST (`224.21` us) and the existing - 64d guard, so it remains rejected. Retesting `KQ_NTHREADS=2,V_NTHREADS=2` - regressed the Qwen-style shape to `268.53` us dual-scale and `226.32` us - FAST, so K/Q remains `1`. -- ROCm/HIP vector FlashAttention now uses a ROCmFP4-owned single-half - Codebook10 expander in K/Q and V decode paths. These FA call sites already - know whether they need the low or high nibble stream, so they no longer pay - to expand both streams and discard one. The focused ROCm0 FA guard improved - from `86.13` / `81.23` us to `82.24` / `78.15` us for the 64d dual-scale / - FAST shapes, and from `247.06` / `221.19` us to `237.12` / `206.50` us for - the Qwen-style 128d shapes. The Qwen3.6 27B MTP guard held at `33.5 tok/s` - short and `27.7 tok/s` sustained in the full serial gate, so this is - promoted. -- ROCm/HIP vector FlashAttention also specializes the ROCmFP4 K/Q path when - `GGML_ROCMFP4_FATTN_KQ_NTHREADS=1`. Each thread owns the full head dot in - this promoted setting, so the kernel now expands both low/high packed - Codebook10 streams once per ROCmFP4 block and accumulates both half-blocks - together instead of loading the same packed bytes twice. The full serial gate - measured 64d FlashAttention at `81.62` / `78.13` us for dual-scale / FAST, - and the wider Qwen-style 128d guard improved from `237.12` / `206.50` us to - `228.58` / `199.32` us. Qwen3.6 27B MTP held `33.2 tok/s` short and - `27.7 tok/s` sustained, so this is promoted as a real Qwen-relevant FA - micro-optimization. - A post-specialization retest of `GGML_ROCMFP4_FATTN_V_NTHREADS=4` was - rejected. It passed the tightened FA guard and nudged the Qwen-style - dual-scale microbench to `228.33` us, but regressed 64d dual-scale to - `86.30` us and Qwen-style FAST to `201.81` us. Qwen3.6 27B MTP stayed at - `27.7 tok/s` sustained, so the promoted V-side default remains `2`. -- ROCm/HIP vector FlashAttention now uses a ROCmFP4-only V dequant rows-per- - thread default of `8`. The ROCmFP4 V helper supports 8-value chunks, and the - post-unaligned-load retest produced a real FA win: 64d dual-scale / FAST - `68.82` / `66.32` us and Qwen-style 128d dual-scale / FAST `201.13` / - `172.22` us. Qwen3.6 27B MTP held `33.5 tok/s` short and `27.7 tok/s` - sustained, so this is now promoted. It can be isolated with - `-DGGML_ROCMFP4_FATTN_V_ROWS_PER_THREAD=4` to return to the prior setting. - Retesting `GGML_ROCMFP4_FATTN_V_NTHREADS=4` on top of the 8-row default - improved only the Qwen-style dual-scale FA microbench (`187.72` us) while - regressing 64d dual-scale / FAST to `77.35` / `77.25` us and Qwen-style FAST - to `182.56` us. Qwen3.6 27B MTP tied at `33.5` / `27.7 tok/s`, so the - shipped V thread-group default remains `2`. - Retesting `GGML_ROCMFP4_FATTN_V_NTHREADS=8` on top of the 8-row default - regressed every focused FA row, including Qwen-style 128d dual-scale / FAST - at `208.94` / `200.45` us, so it was rejected without a longer MTP run. - Retesting `GGML_ROCMFP4_FATTN_KQ_NTHREADS=2` on top of the 8-row default - also regressed the focused FA guard: 64d dual-scale / FAST measured - `80.68` / `78.27` us and Qwen-style 128d measured `245.84` / `207.04` us. - Because the Qwen-style dual-scale row failed the guard, it was rejected - without a longer MTP run and K/Q remains `1`. -- ROCm/HIP vector FlashAttention now has a narrow dual-scale 128d V-thread - specialization: `GGML_ROCMFP4_FATTN_V_NTHREADS_D128_DUAL=4`. This keeps the - promoted 64d default and all FAST paths on `V_NTHREADS=2`, but uses the - previously promising 4-thread V grouping only for the Qwen-style dual-scale - 128d shape. The full serial gate measured FA at `70.37` / `66.31` us for - 64d dual-scale / FAST and `188.75` / `171.89` us for Qwen-style 128d - dual-scale / FAST, while Qwen3.6 27B MTP held `33.7 tok/s` short and - `27.9 tok/s` sustained with no KFD PIDs left running. - Retesting `GGML_ROCMFP4_FATTN_V_NTHREADS_D128_DUAL=8` was rejected. It - slightly improved the 64d dual-scale row (`69.40` us versus a same-session - `70.92` us promoted build), but regressed the Qwen-style 128d dual-scale row - from `194.40` to `211.10` us/run. Because long-context Qwen is the relevant - guard, the promoted D128 dual-scale V grouping remains `4`. - `GGML_ROCMFP4_FATTN_V_ROWS_PER_THREAD=16` was rejected during compilation: - the ROCmFP4 V dequantizer intentionally supports only `2`, `4`, and `8` - rows per thread, and the fixed-copy helper does not support the resulting - 32-byte move. The source now rejects unsupported values with a direct - ROCmFP4 compile-time error. - Retesting `GGML_ROCMFP4_FATTN_V_ROWS_PER_THREAD=2` on the promoted - D128-specialized build was rejected by the focused ROCm FlashAttention - guard. It regressed 64d dual-scale / FAST to `94.31` / `88.77` us and - Qwen-style 128d dual-scale / FAST to `270.00` / `223.88` us, so the - promoted rows-per-thread default remains `8`. -- Vulkan ROCmFP4 scale decode now uses a shared UE4M3 lookup table with - ROCmFP4's half-scale semantics. This moved the focused Vulkan dual-scale - `MUL_MAT` guard from `82.86`, `120.77`, and `181.28` us/run to `65.05`, - `83.07`, and `122.70` us/run for `n=1/2/4`. On Qwen3.6 27B MTP at 262k - context, the same change moved Vulkan sustained output from the older - `20.4 tok/s` at `--spec-draft-n-max 4` to `25.0 tok/s`; `n-max 3` now - reaches `25.3 tok/s` sustained. ROCm0 remains the promoted backend because - it still holds `33.5 tok/s` short and `27.7 tok/s` sustained. - A post-LUT Vulkan runtime sweep found a better fallback profile with q8 KV - and q8 draft KV: `--spec-draft-n-max 4` reached `34.8 tok/s` short and - `27.0 tok/s` sustained. q8 with `n-max 5` improved only the short burst - (`47.8 tok/s`) and regressed sustained output to `23.0 tok/s`; f16 KV - regressed sustained output to `22.5 tok/s`. - Follow-up isolation showed the Vulkan sustained gain comes from the main KV - cache rather than the draft KV cache: q4 main KV with q8 draft KV reached - only `34.6 tok/s` short and `25.0 tok/s` sustained, while q8 main KV with - q4 draft KV reached `34.7 tok/s` short and `26.9 tok/s` sustained. For a - Vulkan fallback, q8 main KV plus q4 draft KV is therefore the leaner near-tie - profile. Splitting q8 across only one accepted KV side was also rejected: - q8 main K with q4 main V reached `34.8 tok/s` short and `25.4 tok/s` - sustained, while q4 main K with q8 main V reached `34.6 tok/s` short and - `23.7 tok/s` sustained. The Vulkan fallback needs both accepted K and V at - q8. Adding mild acceptance filtering to the lean fallback - (`--spec-draft-p-min 0.25`) tied full q8/q8 at `27.0 tok/s` sustained while - keeping draft KV at q4; adding `--spec-draft-n-min 1`, stricter `p-min 0.75`, - and `p-split` checks stayed at `26.9 tok/s`. Retrying `n-max 5` with q8 main - KV, q4 draft KV, and - `p-min 0.25` still produced only a burst win (`47.8 tok/s` short) while - sustained output stayed at `23.0 tok/s`, so `n-max 4` remains the Vulkan - fallback setting. ROCm0 q4/q4 remains the overall promoted backend/profile. - Replacing the shared Codebook10 table with inline integer decode was tested - and rejected because it regressed the focused Vulkan FAST `n=1` guard to - `99.43` us/run. -- ROCm/HIP fallback dequant, copy, get-rows, GPU-side quantization scoring, - and standalone dequant helpers use ROCmFP4-owned HIP helpers for finite - scales and Codebook10 nibbles instead of relying on generic FP8 handling. - This keeps non-MMQ conversion paths aligned with the custom AMD format. -- A branchless HIP scalar Codebook10 nibble decoder was tested and rejected. - It passed the focused ROCm CPY, FlashAttention, and Qwen MTP guards, but - did not improve end-to-end decode. Qwen3.6 27B MTP measured `33.4 tok/s` - short and `27.7 tok/s` sustained, and the focused FlashAttention guard - slowed to `86.38` / `81.13` us for dual-scale / FAST, so the original - scalar decoder remains the default. -- CPU-side Codebook10 table decode in the quantizer/dequantizer was tested - and rejected. The full table variant failed the CPU quant guard with - dequantization at `49.04` cycles/32 for dual-scale and `84.23` cycles/32 for - FAST. The MSE-loop-only variant passed but slowed normal quantization to - `4183.33` / `4018.68` cycles/32 versus the restored arithmetic baseline at - `4034.33` / `3738.85` cycles/32, so the arithmetic CPU decoder remains the - default. -- UE4M3 scale decode in the ROCm/HIP software path uses a ROCmFP4-owned finite - scale decoder. It avoids `ldexpf`, builds normal FP32 values directly from - exponent/mantissa bits, and skips the generic FP8 NaN handling because - ROCmFP4 row validation already rejects non-finite scale bytes. -- A constant-memory HIP lookup table for the finite UE4M3 scale values was - tested and rejected. The latest isolated `GGML_ROCMFP4_USE_SCALE_LUT=1` - pass failed the focused ROCm runtime guard because FAST `n=1` regressed to - `69.48` us/run; prior checks also regressed ROCm CPY source-to-quant paths - and FlashAttention. The arithmetic finite-scale decoder remains the default. -- ROCm/HIP dequant conversion kernels use the same ROCmFP4 finite scale - decoder, keeping tensor conversion aligned with the hot MMQ/MMVQ backend - path instead of falling back to the generic FP8 helper. -- ROCm/HIP backend CPY now advertises and executes quantized - `Q4_0_ROCMFP4 -> F32` and `Q4_0_ROCMFP4_FAST -> F32` conversion paths. - This keeps diagnostic graph ops and fallback tensor conversion inside the - custom AMD decoder instead of being rejected by backend capability checks. - Contiguous q-to-f32 copies now use a ROCmFP4-specific packed-byte kernel: - one HIP thread reads one packed byte and writes the matching low/high - half-block output values. This gives coalesced output writes for normal - contiguous graph copies while the existing stride-aware block kernel remains - the fallback for views and non-contiguous tensors. -- ROCm/HIP backend CPY also supports `F16 -> Q4_0_ROCMFP4`, - `F16 -> Q4_0_ROCMFP4_FAST`, `BF16 -> Q4_0_ROCMFP4`, and - `BF16 -> Q4_0_ROCMFP4_FAST`. The kernels convert each 32-value half/bfloat - block to local FP32 and then run the same exhaustive ROCmFP4 scale search, - so runtime graph copies keep the coherence-first quantizer instead of - falling back to unsupported behavior. -- ROCm/HIP ROCmFP4 source-to-quant and quant-to-F32 CPY wrappers now use - normal multi-thread HIP launch geometry instead of launching one active - thread per quant block. This keeps F32/F16/BF16 runtime quantization and - ROCmFP4 dequantization on the same exact conversion math while removing a - launch-shape bottleneck in helper/fallback graph paths. -- ROCm/HIP ROCmFP4 quant-to-F32 CPY uses ROCmFP4-specific block dequant - helpers that decode each block scale once before unpacking all 32 values. - This avoids repeatedly decoding identical scale bytes through the generic - two-value dequant helper while preserving the same output values. For the - guarded contiguous `8192x512x2` ROCm0 CPY shape, the packed-byte path moved - dual-scale `Q4_0_ROCMFP4 -> F32` from the old `740` us/run band to - `184.48` us/run and FAST `Q4_0_ROCMFP4_FAST -> F32` to `169.99` us/run. - A split launch geometry is now used: source-to-ROCmFP4 quantization uses - 128-thread workgroups, while quant-to-F32 keeps the accepted 64-thread - packed-byte launch. A whole-path 128-thread launch was roughly tied overall - but slightly regressed quant-to-F32; isolating 128 threads to source - quantization preserves the dequant copy win while shaving the source paths. - A 256-thread launch regressed F16 source-to-quant paths and remains rejected. - After the FAST direct-value scoring win, FAST-only 256-thread and 64-thread - source launch splits were rechecked and rejected as well. The 256-thread - split regressed FAST F16 source-to-quant to `1047.24` us/run, and the - 64-thread split measured FAST F32/F16/BF16 `1055.32`, `955.35`, and - `954.78` us/run, so the shared 128-thread source launch remains promoted for - both ROCmFP4 layouts. -- ROCm/HIP contiguous quant-to-F32 CPY shared-scale staging was tested and - rejected. Decoding one block scale into shared memory and synchronizing each - 64-thread launch reduced duplicate scale decode work, but the synchronization - overhead regressed the guarded `8192x512x2` shape: dual-scale - `Q4_0_ROCMFP4 -> F32` moved from `181.84` to `188.63` us/run, and FAST - `Q4_0_ROCMFP4_FAST -> F32` moved from `170.65` to `180.03` us/run. The - direct packed-byte kernel remains promoted. -- ROCm/HIP backend CPY supports same-type packed-block copies for - `Q4_0_ROCMFP4 -> Q4_0_ROCMFP4` and - `Q4_0_ROCMFP4_FAST -> Q4_0_ROCMFP4_FAST`, including block-aligned views. - The kernel copies the packed 18-byte or 17-byte ROCmFP4 blocks directly, so - graph/view copies preserve exact bytes and avoid dequantize/requantize - fallback behavior. The launcher uses normal multi-thread HIP workgroups - rather than one-thread launches, so large packed-view copies scale with the - number of ROCmFP4 blocks. -- ROCm/HIP runtime quantization now finds the finite UE4M3 candidate nearest - `max_abs / 10` with a monotonic binary search, matching the CPU/Vulkan - reference tie behavior while avoiding the older 126-step linear nearest-scale - scan in the HIP copy utility. It also uses the same conservative lower-scale - pruning as the CPU quantizer, so runtime F32/F16/BF16-to-ROCmFP4 copies skip - smaller scales once their unavoidable clipped max-value error cannot beat the - current best exact scale. The HIP max scan uses the same plain absolute - compare as the CPU quantizer, preserving NaN/Inf handling while avoiding - `fmaxf` in the runtime quantization hot loop. -- ROCm/HIP runtime quantization specializes the exact scale search for the - only block shapes used by ROCmFP4 CPY: `0..15`, `16..31`, and `0..31`. - This keeps the same candidate order and tie behavior while letting HIP - compile the dual-scale and FAST source-to-quant paths with fixed offsets. -- ROCm/HIP dual-scale source-to-quant scoring uses a direct Codebook10 value - helper for 16-value half blocks. Final packed quantization still uses the - normal code-index helper, but scale scoring no longer has to map the selected - nibble back through the generic decode helper on the dual-scale path. -- ROCm/HIP FAST source-to-quant scoring now uses the same direct Codebook10 - value helper during scale search. This preserves the exact nearest-value - thresholds and final packed output, but avoids index-then-decode work in the - 32-value FAST scoring path. On the guarded `8192x512x2` ROCm0 CPY shape, - FAST source quantization improved from F32/F16/BF16 `1218.69`, `1138.32`, - and `1138.78` us/run to a repeat guard pass of `1047.21`, `950.93`, and - `951.00` us/run. -- ROCm/HIP `F32 -> ROCmFP4` runtime CPY stages each 32-value block into local - FP32 before running the exhaustive scale search, matching the existing - F16/BF16 source paths. This preserves exact F32 input values but avoids - rereading the global source pointer throughout scale scoring. On the guarded - `8192x512x2` ROCm0 CPY shape, dual-scale F32 source quantization improved - from roughly `9916` to `1117` us/run, and FAST improved from roughly - `10671` to `1231` us/run. -- ROCm/HIP contiguous-only source-to-quant CPY kernels for - `F32 -> ROCmFP4` were tested and rejected. They avoided the generic - multidimensional offset math, but on the guarded `8192x512x2` shape they - did not beat the existing multi-thread generic CPY path and slightly - regressed `F32 -> Q4_0_ROCMFP4_FAST`, so source-to-quant ROCmFP4 CPY keeps - the same guarded implementation for view and contiguous tensors. -- ROCm/HIP backend GET_ROWS supports both ROCmFP4 layouts. This gives pure - ROCmFP4 tensors the same direct row-gather coverage as stock small-block - quants on ROCm and keeps embedding-row access on the custom finite-scale - decoder. -- ROCm/HIP `MUL_MAT` support now covers `F16` activation tensors for both - ROCmFP4 layouts. The backend stages half activations to contiguous FP32 on - the GPU, including non-contiguous/views, then feeds the existing Q8 - activation quantizer and ROCmFP4 MMVQ/MMQ kernels. This keeps the forward - path on the AMD backend instead of rejecting the op and falling through to a - slower dequantized matrix path. The generic matmul runtime guard explicitly - allows this ROCmFP4 x F16 forward-inference case, so the support probe and - execution wrapper agree for batched activations. -- The standalone HIP dequant skeleton covers both the dual-scale and FAST - single-scale layouts, so future fused ROCm kernels can target the current - balanced FAST artifact without reintroducing the older scale path. -- The standalone HIP dequant launch now maps one thread to one packed - ROCmFP4 byte across a 256-thread global grid. This avoids the older - one-16-thread-block-per-32-values launch shape and gives future fused or - diagnostic dequant paths normal GPU occupancy scaling. -- Vulkan ROCmFP4 shaders also decode UE4M3 scales directly to the half-scale - value used by the codebook, matching CPU/HIP and avoiding repeated `* 0.5` - fixups at dequant and matmul call sites. -- Vulkan ROCmFP4 shaders keep a shared `kvalues_rocmfp4` Codebook10 table. - Arithmetic/direct Codebook10 decode variants compiled and preserved - coherence, but measured slower on Strix Halo Vulkan, so the table path - remains the active backend implementation. -- Vulkan `dequantize4()` for ROCmFP4 and ROCmFP4_FAST decodes each block's - UE4M3 scale once per 4-value vector instead of calling the 2-value helper - twice. This improves tested dual-scale ROCmFP4 small-batch matvec shapes - while keeping the promoted Vulkan runtime guard clean. -- Vulkan `Q4_0_ROCMFP4_FAST` matvec/MMQ kernels have a single-scale dot - specialization. They combine the two half-block dot sums and apply the one - FAST scale once, instead of taking the dual-scale path used by - `Q4_0_ROCMFP4`. -- Vulkan `Q4_0_ROCMFP4_FAST` MMQ stores its block scale as a scalar in - shared/register cache instead of duplicating it into a `vec2`. The focused - Strix Halo Vulkan `MUL_MAT` microbench for - `m=4096,n=1,k=14336,type_a=q4_0_rocmfp4_fast` improved from `62.18` to - `61.45` us/run. -- A Vulkan packed16 view for ROCmFP4 quant bytes was tested and rejected. It - compiled, but the focused FAST MMQ guard regressed to `83.03` us/run from the - accepted `61`-`62` us/run range, so ROCmFP4 Vulkan keeps the byte-view load - path. -- Vulkan backend CPY/SET_ROWS now has generated `F32 -> Q4_0_ROCMFP4`, - `F32 -> Q4_0_ROCMFP4_FAST`, `Q4_0_ROCMFP4 -> F32`, - `Q4_0_ROCMFP4_FAST -> F32`, and indexed SET_ROWS shaders. The SET_ROWS path - uses the same exhaustive finite UE4M3 scale search as the CPU reference, so - quantized K/V cache writes favor coherence over a cheap max-abs shortcut. -- Vulkan `F32 -> ROCmFP4` runtime quantization now uses the same exact ordered - UE4M3 scale search as CPU/HIP: find the scale nearest `max_abs / 10`, expand - outward, and stop a candidate once its partial error cannot beat the current - best scale. The candidate set is unchanged, so this avoids a slower linear - scan without falling back to a lower-quality shortcut. -- Vulkan source-to-ROCmFP4 runtime quantization now also prunes lower scale - candidates once clipping the block max alone cannot beat the current best - error. This mirrors the CPU/HIP scale search bound and keeps the candidate - set exact. The 2026-05-25 Vulkan CPY guard passed after this shader change: - F32/F16/BF16-to-dual measured `9525.39`, `2350.54`, and `2418.09` us/run, - dual-to-F32 `516.65` us/run, F32/F16/BF16-to-FAST `10111.85`, `2923.67`, - and `2949.42` us/run, and FAST-to-F32 `509.65` us/run. The full promoted - gate passed after rebuild with Qwen3.6 27B MTP at `33.9` / `28.0 tok/s` and - no KFD PIDs left running. -- Vulkan backend CPY also supports `F16 -> Q4_0_ROCMFP4`, - `F16 -> Q4_0_ROCMFP4_FAST`, `BF16 -> Q4_0_ROCMFP4`, and - `BF16 -> Q4_0_ROCMFP4_FAST`. The runtime quantization shader can load - `float`, `float16_t`, and BF16 source bits and then runs the same exact - ordered finite UE4M3 scale search. Backend tests keep a bounded NMSE - tolerance only for the half/bfloat runtime quantization cases because those - paths are inherently lossy around source-precision tie points; the - `F32 -> ROCmFP4` checks remain strict. -- Vulkan same-type CPY supports packed-block copies for - `Q4_0_ROCMFP4 -> Q4_0_ROCMFP4` and - `Q4_0_ROCMFP4_FAST -> Q4_0_ROCMFP4_FAST`, including block-aligned - non-contiguous/permuted/view copies. The non-contiguous path uses a - byte-addressed block shader and preserves exact 18-byte or 17-byte - ROCmFP4 blocks. Contiguous same-type dual-scale and FAST copies now both use - the direct byte-copy path, avoiding the generic halfword copy route for - ROCmFP4's custom 18-byte and 17-byte block layouts. -- Vulkan CPY is now covered by a dedicated regression guard so copy-path - changes cannot silently fall back or regress outside the ROCm-only CPY gate. - The guard runs same-type and source/dequant CPY correctness before measuring - the large copy performance shape, and now streams the performance phase - through `tee` so long Vulkan runs do not look idle to the command runner. - The ceilings were tightened after the lower-scale pruning gain, so the old - slow source-to-quant path no longer passes this guard. - On Strix Halo RADV Vulkan, the large guarded shape currently measures - F32/F16/BF16-to-dual at `9525.39`, `2350.54`, and `2418.09` us/run, - dual-to-F32 at `516.65` us/run, F32/F16/BF16-to-FAST at `10111.85`, - `2923.67`, and `2949.42` us/run, and FAST-to-F32 at `509.65` us/run. -- Vulkan scalar FlashAttention can now decode ROCmFP4 and ROCmFP4_FAST K/V - cache blocks. ROCmFP4 K/V is forced to the scalar FA path because the current - custom decode is not a coopmat/native matrix-core FP4 path. -- Vulkan scalar FlashAttention can use the integer-dot MMQ K path for both - ROCmFP4 K-cache layouts. The FAST layout expands each 4-bit Codebook10 value - into packed signed int8 lanes and uses its single UE4M3 scale as the K block - multiplier. The dual-scale layout also uses packed signed int8 lanes, but - splits the dot accumulation by half-block so each 16-value half uses its own - UE4M3 scale. This keeps the quality-biased STRIX K-cache path fast without - applying one scale to a two-scale block. -- Build and runtime verification generated the Vulkan SPIR-V entries for - ROCmFP4 copy/SET_ROWS shaders, linked `libggml-vulkan.so`, and passed - Vulkan ROCmFP4 CPY plus MUL_MAT smoke tests on Strix Halo. -- Row validation rejects invalid scale bytes outside finite unsigned UE4M3 - (`0x00` through `0x7e`) so corrupted custom GGUF tensors fail early. -- Quantization keeps the exhaustive 126-scale UE4M3 search for both normal and - imatrix paths. Candidate-window scale search was tested and improved GGUF - creation speed, but it regressed the Qwen3-4B short WikiText-2 PPL on the - compact FAST path, so it was rejected for coherence. -- The exhaustive scale search now visits the UE4M3 candidate nearest the - block's `max_abs / 10` first using a monotonic binary search, expands - outward, and exits a candidate scale once its partial error cannot beat the - current best scale. This remains exact because every finite scale is still - evaluated; on the Qwen3-4B FAST_COHERENT artifact it produced a - byte-identical GGUF while cutting FAST quantization cost sharply. -- CPU scale decode now uses a 127-entry finite UE4M3 half-scale table for the - exhaustive scale search and row dequantization. The table preserves the same - exact FP32 values as the former bit-construction decoder, but avoids - rebuilding them for every scale candidate. -- CPU scale search now has separate unweighted and imatrix-weighted MSE - scoring paths. The normal path avoids per-value weight branches, while the - imatrix path precomputes the row-energy calibration weight once per - 16/32-value block instead of recomputing the same `sqrtf` term for every - candidate scale. -- CPU normal quantization scans each block once for finite values and uses a - finite-only nearest-Codebook10 helper in the exhaustive MSE loop when the - block is clean. Non-finite blocks still use the guarded helper. This - promoted conversion-speed path measured focused dual-scale / FAST normal - quantization at `3844.38` / `3582.57` cycles per 32 values in the latest - guard. -- CPU imatrix-weighted scale-MSE scoring now uses the same finite-only - nearest-Codebook10 helper when the source block is finite. This preserves the - guarded path for non-finite input while improving FAST imatrix GGUF creation: - same-session pre-candidate FAST imatrix was `5258.07` cycles / 32 values, and - two guarded candidate passes measured `4448.73` and `4447.32`. Dual imatrix - stayed in the noisy guarded band, so the claim is limited to FAST imatrix. -- The weighted and unweighted exhaustive scale loops are split as well, so - the normal quantizer does not branch on imatrix state for every finite - UE4M3 candidate. This keeps the exact candidate order and tie behavior while - improving CPU GGUF creation speed for both ROCmFP4 layouts. -- The CPU quantizers fill every packed nibble byte in each ROCmFP4 block, so - they no longer clear `qs` before packing. This is an exact store cleanup: - correctness stayed clean, `q4_0_rocmfp4` quantize improved to `5244.46` - cycles / 32 values, `q4_0_rocmfp4_fast` improved to `4668.28` cycles / 32 - values. -- CPU scale selection scans block maxima with a plain absolute-value compare - instead of `fmaxf`. NaNs still do not raise the maximum, infinities are still - rejected before scale search, and finite output is unchanged. This moved - `q4_0_rocmfp4` quantize to `5228.64` cycles / 32 values and FAST to - `4516.45` cycles / 32 values. -- CPU dequantization and quantization-error scoring use the ROCmFP4 arithmetic - Codebook10 decoder, which avoids a table fetch per unpacked nibble. CPU - fallback vec-dot keeps the 16-entry codebook table because measured Strix - Halo fallback dot speed was better with the table there. This hybrid keeps - the dequant win without regressing CPU vec-dot. -- CPU fallback vec-dot now reuses each packed ROCmFP4 byte for both low and - high nibbles before table decode. This preserves exact output, moved focused - dual-scale vec-dot from `31.86` to the `29.77`-`29.82` cycles / 32 values - band, and kept FAST in the `27.04`-`27.06` cycles / 32 values band. -- Two additional CPU decode shortcuts were rechecked on 2026-05-24 and - rejected. Replacing arithmetic Codebook10 decode with table decode in - row dequantization and scale-MSE scoring slowed CPU dequantization from the - guarded `33`-cycle band to `51`-`84` cycles / 32 values. Returning a direct - decoded value during MSE scoring instead of index-then-decode also passed - correctness but regressed normal quantization in the measured guard, so the - original arithmetic decoder remains the CPU path. A narrower full-block - weighted-MSE-only retry was also rejected because it regressed the focused - FAST imatrix timing to `5007.73` cycles / 32 values. -- A direct finite-scale table helper for CPU quantizer scale-search candidates - was also rejected. It helped dual-scale normal quantization, but repeat - guard runs regressed FAST normal quantization to `4043.60` and - `4289.66` cycles / 32 values. The guarded scale helper remains in place - because the compact STRIX_LEAN preset depends heavily on FAST tensors. -- NaN-only and branchless finite-scan variants were also rejected for default. - The NaN-only scan was noisy and the same-session `isfinite()` scan measured - better dual-scale normal quantization (`3735.41` vs `3776.53` cycles / 32 - values), while the branchless boolean-and scan regressed FAST normal - quantization to `3773.44` cycles / 32 values. -- Per-value Codebook10 quantization uses exact nearest-neighbor thresholds - instead of a 16-entry scan. The hot quantizer path uses one reciprocal scale - per candidate/block and multiplies each value by that reciprocal instead of - dividing per value. On the Qwen3-4B FAST_COHERENT check this kept PPL tied - with the accepted artifact while cutting GGUF creation time further. -- CPU exhaustive scale search now prunes lower-scale candidates after the - clipped max-value error alone cannot beat the current best error. The - imatrix path uses the positive calibration weight of the max element for the - same conservative bound. This does not change accepted values because every - skipped smaller scale has a larger unavoidable clip error. The weighted path - also combines imatrix weight preparation, max-absolute scan, and max-value - pruning-weight selection into one pre-scan, while both exhaustive loops stop - once no valid lower or upper scale candidates remain. Latest 40-iteration - quant guard run: `q4_0_rocmfp4` normal `4049.28` cycles / 32 values, FAST - normal `3721.48`, imatrix dual-scale `5251.76`, imatrix FAST `4898.75`. -- Adding `GGML_RESTRICT` to the local CPU scale-scoring helper pointers was - tested and rejected. It compiled and passed the quant guard, but did not - improve normal quantization and made the imatrix guard noisier/slower in - the measured pass, so the existing helper signatures were kept. -- Regression guards: - - `scripts/check-rocmfp4-deepseek-regression.sh` is an optional compatibility - smoke guard for a second ROCmFP4-converted model family. It is not part of - the promoted-gain gate because no reproducible DeepSeek speedup has been - established yet. The default all-regression script skips it unless - `INCLUDE_DEEPSEEK_SMOKE=1` is set. - - `scripts/check-rocmfp4-qwen-mtp-regression.sh` verifies the promoted - Qwen3.6 27B MTP ROCmFP4 262k-context `draft-mtp` path. The stable guard - uses ROCm0 and `--spec-draft-n-max 4`. On ROCm0, `n-max 4` improved the - short guard prompt from `27.7` to `33.6 tok/s` versus `n-max 3`, and the - longer forced-output prompt from `25.6` to `26.3 tok/s`; the dual-scale - MMVQ VDR tune then moved the longer prompt to `27.8 tok/s`. `n-max 5` - and `n-max 6` improved only the bursty short prompt after the MMVQ tune - but regressed sustained output to `24.8` and `24.0 tok/s`, respectively. - Follow-up `n-max 5` checks with `--spec-draft-p-min 0.75`, - `--spec-draft-p-min 0.90`, and `--spec-draft-n-min 1` still held the - short prompt at `45.0`-`45.1 tok/s` but kept sustained output at only - `24.7 tok/s`, so `n-max 4` remains promoted. - The guard now checks both short and sustained prompts so high-acceptance - best-case gains do not hide sustained-output regressions. - Additional ROCm0 checks rejected larger batch sizes, smaller ubatch, - q8/f16 KV cache, `--swa-full`, `--no-host`, `--no-op-offload`, - `--no-repack`, polling changes, lower and higher CPU thread counts, - greedy sampling, backend sampling, p-split changes, sampler chain trimming, - and combined MTP+ngram speculation because none improved the sustained - prompt. After the MMVQ VDR tune, `-b 1024 -ub 512`, `-b 2048 -ub 512`, - and `-b 512 -ub 256` still tied the promoted `27.8 tok/s` sustained - result, while `-b 1024 -ub 1024` and - `--poll-batch 1 --spec-draft-poll-batch 1` stayed at `27.7 tok/s`. - q8 and f16 KV cache dropped sustained decode to `25.4` and `26.0 tok/s`. - The MTP draft loop now honors `--spec-draft-p-min`. With that cutoff active, - `n-max 4, p-min 0.75` tied the promoted path at `33.5 tok/s` short and - `27.6 tok/s` sustained, while `n-max 5` stayed burst-only at `45.0`-`45.1` - tok/s short and `24.6`-`24.7 tok/s` sustained for `p-min 0.75` and `0.90`. - Follow-up ROCm0 KV isolation confirmed this is not a draft-cache issue: - q8 main KV with q4 draft KV measured `33.5 tok/s` short and `25.3 tok/s` - sustained, q8 main K only measured `31.5` and `21.4 tok/s`, and q8 main V - only measured `31.1` and `21.9 tok/s`. The promoted ROCm0 path therefore - keeps both accepted and draft KV at q4. - `--spec-draft-p-split 0.05` and `0.20` both tied the `27.7 tok/s` - sustained guard, `-t 24 -tb 32 --spec-draft-threads 24 - --spec-draft-threads-batch 32` tied, and trimming the sampler chain to - `top_k;top_p;temperature` regressed sustained decode to `26.6 tok/s`. - Draft-only q8 KV (`SPEC_DRAFT_TYPE_K=q8_0`, - `SPEC_DRAFT_TYPE_V=q8_0`) with main KV left at q4 tied the promoted path - at `33.6 tok/s` short and `27.7 tok/s` sustained, so the leaner q4 draft - KV default remains promoted. - The heavier Qwen3.6 27B MTP `STRIX_MTP_Q6` ROCmFP4 profile was also - checked with the same ROCm0 guard. It reached `30.1 tok/s` on the short - prompt but only `21.3 tok/s` sustained, below the guard floor, so the - Q6/quality-biased profile is not promoted for throughput. - The guard script supports `SPEC_DRAFT_N_MAX`, `SPEC_DRAFT_N_MIN`, - `SPEC_DRAFT_P_MIN`, `SPEC_DRAFT_P_SPLIT`, `THREADS`, `THREADS_BATCH`, - `SPEC_DRAFT_THREADS`, `SPEC_DRAFT_THREADS_BATCH`, `SAMPLERS`, - `BATCH_SIZE`, `UBATCH_SIZE`, `CACHE_TYPE_K`, `CACHE_TYPE_V`, - `SPEC_DRAFT_TYPE_K`, `SPEC_DRAFT_TYPE_V`, `EXTRA_ARGS`, and - `SPEC_EXTRA_ARGS` environment overrides for - controlled sweeps while defaulting to the promoted `n-max 4`, `n-min 0`, - `p-min 0.0`, `p-split 0.10`, q4 KV, `-t 16`, `-tb 32`, `-b 512`, and - `-ub 512` settings. - - `scripts/check-rocmfp4-quant-regression.sh` runs quant correctness plus - CPU quantizer, dequantizer, and vec-dot cycle ceilings for both ROCmFP4 - block layouts. It checks normal and imatrix quantization, and now also - protects CPU fallback dequant/vec-dot paths so decode-helper experiments - cannot pass while slowing non-GPU fallbacks. Recent pass after keeping the - `isfinite()` finite-block scoring promotion and adding the weighted/imatrix - finite scorer: dual-scale quant `3844.38`, FAST quant `3582.57`, dual - dequant `33.59`, FAST dequant `33.13`, dual vec-dot `29.96`, FAST vec-dot - `27.03`, dual imatrix `5587.43`, and FAST imatrix `4447.32` cycles / 32 - values. - - `scripts/check-rocmfp4-vulkan-runtime-regression.sh` measures focused - Vulkan `MUL_MAT` runtime for ROCmFP4 FAST and dual-scale layouts, catching - shader regressions that can be hidden by end-to-end decode noise. The - guard covers `n=1`, `n=2`, `n=4`, and `n=8` for both layouts. Recent - tightened serial pass measured FAST `55.82`, `71.59`, `105.10`, and - `163.41` us/run for `n=1/2/4/8`, and dual-scale `64.87`, `83.24`, - `118.56`, and `194.27` us/run for `n=1/2/4/8`. The previous serial pass - after adding the shared ROCmFP4 UE4M3 - scale LUT was FAST `53.66`, `71.67`, `105.14` us/run and dual-scale - `65.05`, `83.07`, `122.70` us/run for the same shapes. - - `scripts/check-rocmfp4-vulkan-cpy-regression.sh` measures Vulkan0 CPY for - `F32/F16/BF16 -> Q4_0_ROCMFP4`, - `F32/F16/BF16 -> Q4_0_ROCMFP4_FAST`, and the matching quant-to-F32 - dequant copy paths on the same large shape used by the ROCm CPY guard. - It is included in the all-regression harness to catch accidental Vulkan - copy fallback or shader-routing regressions. - - `scripts/check-rocmfp4-rocm-runtime-regression.sh` measures the same - focused `MUL_MAT` shapes on ROCm0. The guard covers `n=1`, `n=2`, `n=4`, - and `n=8` for both FAST and dual-scale ROCmFP4 so MTP-style multi-column - regressions are caught instead of only protecting single-token matvec. - Recent tightened serial pass after extending the RDNA3.5 two-warp route - through `n=2` measured FAST `51.66`, `66.56`, `101.27`, and `168.84` - us/run for `n=1/2/4/8`, and dual-scale `53.66`, `58.40`, `87.32`, and - `148.26` us/run for `n=1/2/4/8`. The `n=8` guard was added after a - rejected wide-rows candidate regressed dual-scale `n=8` to `1382.72` - us/run. - - `scripts/check-rocmfp4-rocm-cpy-regression.sh` measures ROCm0 CPY for - `F32/F16/BF16 -> Q4_0_ROCMFP4`, - `F32/F16/BF16 -> Q4_0_ROCMFP4_FAST`, and the matching quant-to-F32 - dequant copy paths on a large `8192x512x2` shape. Recent serial-gate pass - after direct FAST value scoring: F32/F16/BF16-to-dual `1111.73`, - `1008.69`, `1006.93` us/run, dual-to-F32 `182.25` us/run, - F32/F16/BF16-to-FAST `1047.21`, `950.93`, `951.00` us/run, and - FAST-to-F32 `170.36` us/run. - - `scripts/check-rocmfp4-all-regression.sh` runs the promoted-gain gate: - quant, Vulkan runtime, Vulkan CPY, ROCm runtime, ROCm FlashAttention, - ROCm CPY, and Qwen MTP guards serially, then checks ROCm KFD PIDs. Runtime - microbenchmarks should use this serial path rather than being run in - parallel with other GPU/UMA workloads. DeepSeek is not part of this - promoted-gain gate because no reproducible DeepSeek speedup has been - established; run the separate compatibility smoke only when explicitly - needed with `INCLUDE_DEEPSEEK_SMOKE=1`. The K/Q block-pair FlashAttention - serial pass held Qwen3.6 27B MTP at `33.2 tok/s` short and `27.7 tok/s` - sustained, with no KFD PIDs left running. The same pass measured ROCm - runtime `MUL_MAT` at FAST `54.16` / `66.13` / `101.73` / `178.36` us and - dual-scale `51.65` / `57.98` / `88.33` / `148.48` us for `n=1/2/4/8`, - and ROCm FlashAttention at `81.62` / `78.13` us for 64d dual-scale / FAST - and `228.58` / `199.32` us for Qwen-style 128d dual-scale / FAST. - - The MTP `accept()` path now skips re-copying `pending_h` when acceptance - lands on the final verify row already staged by `process()`. The focused - Qwen MTP guard held `33.8 tok/s` short and `27.9 tok/s` sustained after - this host-side cleanup. - - The MTP `process()` path now stores only the non-final verify rows needed - for partial-accept rollback, while copying the final target hidden row - directly to `pending_h` for the next MTP step. The focused Qwen MTP guard - held `33.9 tok/s` short and `27.9 tok/s` sustained, and the full serial - gate held `33.7 tok/s` short and `27.9 tok/s` sustained after this cleanup. - - The simple draft and MTP draft paths now return before - `llama_decode(ctx_dft, batch)` when no sequence is actively drafting. The - focused Qwen MTP guard held `33.8 tok/s` short and `28.0 tok/s` sustained, - and the full serial gate held `33.7 tok/s` short and `27.9 tok/s` - sustained after this idle/no-draft cleanup. - - The simple draft path now uses a reusable `uint8_t` drafting-state buffer - instead of allocating `std::vector` per draft call. The focused Qwen - MTP guard held `33.7 tok/s` short and `28.0 tok/s` sustained, and the full - serial gate held `33.8 tok/s` short and `27.9 tok/s` sustained. - - The MTP draft loop now skips its debug-candidate loop entirely unless - debug logging is enabled, hoists the debug verbosity state once per draft - call, and uses direct vector indexing in the hot per-token path. The - focused Qwen MTP guard held `33.8 tok/s` short and `27.9 tok/s` sustained - after this cleanup, so it is kept as a low-risk host-side simplification - rather than claimed as a decode-speed gain. - - The simple and MTP draft paths now use a shared direct one-sequence batch - append helper instead of `common_batch_add(..., { seq_id }, ...)` in the - hot speculative path. This avoids a temporary sequence-id container without - changing multi-sequence batch behavior elsewhere. The focused Qwen MTP - guard held `33.9 tok/s` short and `27.9 tok/s` sustained, and the full - serial gate held `33.8 tok/s` short and `27.9 tok/s` sustained. - - The MTP verify-row buffer now reserves for the configured draft depth and - only grows when needed instead of shrinking/resizing on every verification - pass. The focused Qwen MTP guard held `33.8 tok/s` short and `27.9 tok/s` - sustained, and the full serial gate held `33.9 tok/s` short and - `27.9 tok/s` sustained with no KFD PIDs left running. - - The MTP `process()` path now copies retained verification hidden rows from - the target embedding buffer in one contiguous `memcpy()` instead of one - `llama_get_embeddings_pre_norm_ith()` plus `memcpy()` per row. Rollback - behavior is unchanged. The focused Qwen3.6 27B MTP guard held - `33.7 tok/s` short and `27.9 tok/s` sustained, and the 35B A3B guard held - `104.1 tok/s` short and `89.2 tok/s` sustained. The same build later - passed the full serial all-regression gate with `INCLUDE_QWEN35_A3B_GUARD=1`, - including Qwen3.6 27B MTP at `33.8` / `27.9 tok/s` and Qwen3.6 35B A3B MTP - at `104.1` / `89.3 tok/s`. - - A matching contiguous-pointer cleanup inside the MTP `draft()` loop was - tested and rejected. It replaced per-row - `llama_get_embeddings_pre_norm_ith(ctx_dft, i_batch)` calls with one - `llama_get_embeddings_pre_norm(ctx_dft)` pointer per draft decode - iteration. The 27B MTP guard held at `33.8` / `27.9 tok/s`, but the 35B A3B - repeat measured `104.3` / `88.7` and `104.3` / `89.2 tok/s`, below the - promoted `89.3 tok/s` sustained band, so the code change was removed. - - A single-sequence MTP `draft()` fast path was tested and rejected on - 2026-05-25. It removed the active-sequence bookkeeping loop for the common - `n_seq == 1` case and passed the dense 27B guard at `33.7` / `28.0 tok/s`, - but the 35B A3B sustained guard collapsed to `25.7 tok/s` despite a - passing `103.1 tok/s` short check. Reverting that path restored the 35B A3B - guard to `104.3` / `90.3 tok/s`, so the shared multi-sequence draft loop - remains the promoted implementation. - - A dual-scale-only finite-pack CPU quantizer shortcut was tested and - rejected on 2026-05-24. It passed correctness, but even after isolating - the shared scale chooser it regressed the protected FAST quant path - (`q4_0_rocmfp4_fast` normal quant rose into the `3882`-`4022` cycles / 32 - values band versus the clean `3623` cycles / 32 values baseline). The - final packing loops therefore remain on the guarded nearest-code helper. -- The Strix ROCmFP4 build script now builds the quant regression test - binaries (`test-quantize-fns`, `test-quantize-perf`, and - `test-backend-ops`) alongside `llama-cli`, `llama-quantize`, and - `llama-bench`, so quant and runtime guards work from a clean build - directory. -- `test-quantize-perf --imatrix` benchmarks the ROCmFP4 quality/coherence - path through `ggml_quantize_chunk(..., imatrix)` with synthetic importance - weights. The quant regression guard includes this mode to reject imatrix-side - CPU changes that would not show up in the normal non-imatrix timing. +## Layout -High-upside Strix-specific work: -- The next significant speed step is likely a fused ROCmFP4 decode-and-dot - ROCm matvec path. The current ROCmFP4 wins come from compact blocks and - avoiding generic decode/copy overhead; a fused path would keep Codebook10 - values and UE4M3 scales in registers/shared memory through the dot product - instead of materializing wider intermediates. -- A ROCmFP4-aware long-context attention path is the second major target. The - long-context limit is mostly KV traffic, FlashAttention shape efficiency, and - memory bandwidth. The current dual-scale layout protects coherence, but it is - not itself a large speed lever unless the attention kernels consume it - directly and efficiently. -- MTP target/draft overlap is a possible scheduler project, not a flag. The - current common MTP flow is serial on one Strix Halo ROCm device. Real overlap - would need scheduler changes plus acceptance/correctness guards, and it - should only be promoted if it beats the sustained Qwen 262k guard. -- Coherence should stay protected by tensor-aware ROCmFP4 profiles: dual-scale - for sensitive tensors and FAST only where guarded model tests show no - sustained decode or quality regression. Pure speed-only profiles are not - promoted in this tree without the serial regression gate. +32 weights per block. Each weight is a 4-bit code: sign bit plus a 3-bit index +into the magnitude table `0, 1, 2, 3, 4, 6, 8, 10`. The low nibbles of the 16 +payload bytes are weights 0-15, the high nibbles weights 16-31.

It includes custom Vulkan and ROCm/HIP handling for the new GGUF - types, but it is not yet a native rocWMMA FP4 tensor-core implementation. - Current speed gains come from the compact block layout and backend decode - paths; deeper rocWMMA/cooperative-matrix work is future optimization work. -- NVIDIA CUDA is disabled in the Strix-FP4 build (`-DGGML_CUDA=OFF`). Some - upstream llama.cpp HIP backend sources still live under - `ggml/src/ggml-cuda` and are compiled by HIP for AMD, but the ROCmFP4-owned - helper code and user-facing build/run path are ROCm/HIP/Vulkan targeted. - This tree also accepts `GGML_HIP_ENABLE_UNIFIED_MEMORY=1` as the AMD-named - alias for the upstream unified-memory switch. -- The bundled rocWMMA 7.1.0 headers expose gfx12 WMMA paths for FP8/BF8 and - integer 8-bit inputs, but no native FP4 input type or FP4 WMMA/MFMA builtin - is visible locally. A true matrix-core ROCmFP4 path therefore needs a - measured unpack/convert strategy first, such as ROCmFP4 Codebook10 to int8 - WMMA or FP8 WMMA tiles, before claiming native FP4 tensor-core execution. -- rocWMMA FlashAttention is intentionally opt-in via - `GGML_HIP_ROCWMMA_FATTN=ON scripts/build-strix-rocmfp4-mtp.sh`. - It currently compiles with the local rocWMMA headers in - `/path/to/third_party/rocWMMA`, but the Strix Halo benchmark - regressed sustained Qwen MTP decode (`23.3 tok/s` vs the promoted - `26.2 tok/s` default HIP FlashAttention path), so the default build keeps it - disabled. A follow-up on the 35B A3B ROCmFP4 MTP guard measured only - `99.7` / `76.1 tok/s` versus the promoted `104.4` / `89.3` band, so this - remains true for the MoE-heavy profile as well. -- TurboQuant and TriAttention are not present as runtime flags in this isolated - tree. Integrating them would require a source-level merge into `strix-fp4`; - do not claim support or promote them unless they beat the serial ROCmFP4 - regression gate. +| Type | GGUF type id | Payload | Scales | Block bytes | BPW | +|---|---:|---|---|---:|---:| +| `Q4_0_ROCMFP4` | 100 | 16 bytes, 32 nibbles | 2, one per 16-weight half | 18 | 4.50 | +| `Q4_0_ROCMFP4_FAST` | 101 | 16 bytes, 32 nibbles | 1 per block | 17 | 4.25 | + +Type ids match charlie12345/ROCmFPX, so GGUFs quantized there (the published +`*-ROCmFP4-FAST*`, `*-ROCmFP4-STRIX*` files) load here. + +## What is implemented in this tree + +- CPU: quantize / dequantize / vec_dot through the ggml type traits. +- Vulkan: dequant, mat-vec, matmul, and q8_1 integer-dot (MMQ / MMVQ) kernels + under `ggml/src/ggml-vulkan/vulkan-shaders/`. +- Not implemented: ROCm/HIP kernels for these types.

ROCmFP4 - searches each 16-weight half-block; ROCmFP3 and ROCmFP6 follow the same - half-block policy, while ROCmFP8 currently uses one full-block scale. -- Preserve the ROCmFP4 kernel contract: CPU reference quant/dequant/dot first, - then HIP/Vulkan `CPY`, `GET_ROWS`, `SET_ROWS`, `MUL_MAT`, and `MUL_MAT_ID` - paths, with backend-op coverage before claiming runtime support. -- Keep dequant math explicit and deterministic: integer code times decoded - UE4M3 scale.

Flash attention has no decode path for them: fa_kv_ok in ggml-vulkan.cpp rejects all of them, and flash_attn_dequant.glsl has no aliased view for their blocks (block_rocmfp4_fast is 17 bytes, so a *_packed16 view is not expressible for it). Listing them in kv_cache_types made them selectable with -ctk/-ctv and printed them in --help. That combination does not fall back the way an unsupported KV type normally would: all of these types are quantized, a quantized V cache sets flash_attn_type to ENABLED in llama_init_from_model, and that clears auto_fa, which is the guard on the flash attention support probe. The probe that would turn flash attention back off never runs. Also drops the K-type override that silently replaced a requested q3_0_rocmfpx K cache with q6_0_rocmfpx: it changed an explicit user choice behind a warning, and applied to K only, so -ctk q3_0_rocmfpx -ctv q3_0_rocmfpx produced mismatched K and V types.

That bound was computed as max_abs - 31*scale, but rocmfpx_decode_fp6_code() maps code 32 to -32: the representable range is the asymmetric [-32, 31]. For a block whose largest magnitude is negative the bound therefore overestimates the error that cannot be avoided, and the search gives up before reaching the scale that wins. Sweeping 20000 half-blocks with a single dominant outlier: before: 324 suboptimal with a negative outlier, 0 with a positive one after: 0 suboptimal in either case worst observed case: byte 12 at sse 1.783e-04 where byte 11 gives 1.367e-04. The asymmetry between the two columns is exactly what the wrong bound predicts. The Vulkan encoder carried the same bound, so fix both together - the two encoders have to agree on the scale they choose.

The isfinite() guard keeps NaN and inf out, but a large finite weight still overflows the conversion, so the value that gets clamped is already wrong: 1e12 -> fp6 -0.03125 sign flipped 1e30 -> fp6 0, fp8 0 magnitude lost entirely Clamp the float to the representable range first, then convert. For in-range values this is identical to the old order - rounding cannot push a value past a bound it was not already past - so ordinary weights encode bit for bit as before, and the extremes now saturate: 1e12 -> fp6 31*scale, fp8 127*scale 1e30 -> fp6 31*scale, fp8 127*scale The Vulkan encoder had the same shape, and int() of an out-of-range float is undefined in GLSL, so fix it in the same commit to keep the two encoders in agreement. This is extreme-input robustness, not a defect seen on ordinary weights.

Extends the q8_0 dequant-once FA path to every KV-eligible quant type via per-type fused dequant+transpose shaders, plus a prefill-only fa_kv_ok gate for iq4_nl (no native coopmat1 path) and a GGML_VK_FA_DEQUANT env toggle. Correctness: dequant-once == native FA bit-exact for q4_0/q4_1/q5_0/q5_1; iq4_nl matches CPU. Finding: prefill is quant-type independent (all dequant to identical f16 scratch); iq4_nl is a poor KV type (ppl ~2x q4_0 at equal bits). Retained as gating evidence.

On discrete devices that resident footprint can push the working set past free VRAM, at which point the driver silently pages device-local memory: measured ~15x prefill regression on an 8 GB card (RTX 3070, driver 591.86) at long context, with no error reported. Integrated/UMA devices have no separate device pool to overflow and are unaffected. Gate the path on this process's device-local usage against the physical heap size, keeping a conservative reserve for memory not observable in-process. heapBudget is deliberately not used as the signal: ggml_backend_vk_get_device_memory computes heapBudget - heapUsage in unsigned arithmetic, which wraps to a huge value exactly when the device is oversubscribed. The allocation cannot gate itself either - on WDDM vkAllocateMemory only fails at roughly physical heap size, which is above the free-VRAM level where paging begins, so a successful allocation is not evidence of a resident fit. Also fix the scratch size check: K and V are bound as one storage buffer, so their sum must fit maxStorageBufferRange, not each half independently. GGML_VK_FA_DEQUANT=0 forces the path off and =1 skips the capacity check; GGML_VK_FA_DEQUANT_RESERVE_MB overrides the reserve.

Measured on Strix Halo (RADV gfx1151), hd128/GQA8/kv10240/nb2048 f16: 29.8ms contiguous vs 63.1ms dense-permuted (the model layout; matches the in-model 59.9ms from the perf logger, where FLASH_ATTN_EXT was 72.6% of the graph at pp2048@d8192). GGML_VK_FA_KV_CONTIG=1 extends the dequant-once FA scratch to f16 K/V: dequant_f16_transpose.comp is a pure strided copy ([HS,NH,KV] -> [HS,KV,NH], same push-constant ABI and dispatch as the quant transpose shaders), engaged only when the rows are actually strided, prefill only (neq1 >= 64). FA op 63.1 -> 30.5ms (2.07x) incl. copy cost. Model-level (Qwen3-Coder-30B Q6_K_XL, ub2048, f16 KV, r=3, vs ROCm 571d0d5 nowmma): pp8192 877 -> 1199 t/s (ROCm 1216, was -28% now parity); pp2048@d4096/8192/16384: 776/513/300 -> 1120/850/580. Shallow prefill unchanged-to-better (pp2048 1542 -> 1633). Not the fix: shmem staging on AMD (loses on occupancy, 29.8 -> 54.4ms contiguous), bigger-tile/GQA-packed streaming (1-KV-head L2-resident probe runs identical -> kernel is issue-bound, not bandwidth-bound). test-backend-ops -o FLASH_ATTN_EXT green with the flag off and on (pre-existing iq4_nl+sinks failures unchanged).

That made the copy invisible and the kernel look correspondingly slower. Adds a sub-node timestamp: a handler can close an interval mid-node and have it logged under its own name. Measured on Coder-30B UD-Q6_K_XL, pp2048/ub2048 at d32768, f16 KV: graph total 4612.3 ms FLASH_ATTN_EXT 3490.6 ms 75.68% of graph FA_KV_CONTIGUIZE 33.1 ms 0.72% of graph (0.95% of FA) so the copy is under 1% of the graph and FA is 75.7% of it at that depth. Bench throughput is unchanged with the instrumentation compiled in (441.09 vs 442.14 t/s), since the marks are only emitted when the logger is on in per-op mode. Two latent bugs in the query-pool handling fall out of this and are fixed here: - The pool is created with n_nodes+100 slots but only the first n_nodes+1 were reset each graph, so anything using the headroom would read stale results. - The results buffer was sized n_nodes+1 while getQueryPoolResults was asked for query_idx entries. Equal today, but it is an overflow waiting for the first caller that writes an extra timestamp. Sub-op intervals log no flops, since they move bytes rather than doing math; attributing the node's flop count to them would corrupt the GFLOPS column for both halves.

With q8_0 both operands are full int8, so its bound is d_per_step*4*127*127, which overflows f16 when ACC_TYPE is f16 (GGML_PREC_DEFAULT): the score goes +inf, softmax is destroyed and the output comes back -FLT_MAX. Nibble types bound at ~30480 and stay in range, which is why only q8_0 tripped it. Apply the scales in fp32, then narrow. Identical arithmetic when ACC_TYPE is float, so the f32acc path is untouched. This is an upstream bug, not a fork regression, and it was fixed here once before - 61e77f4 carried it and the rebase onto b10133 dropped it. Only the scalar shader has MMQ, so the failing shape is hsk=128 + q8_0 K + prec=def + nb=1 + nr23=[1,1]; GQA>1 and nb>1 route to coopmat1 and escape. test-backend-ops -o FLASH_ATTN_EXT on gfx1151, quiet box: 13295/13295 twice, up from 13257/13295. All 38 failures were type_K=q8_0 prec=def. Both ggml_flash_attn_ext call sites in the tree force GGML_PREC_F32, so no model path reaches this - it is a landmine for the next person touching precision, not a live bug.

The replay went through the same verification as a fresh draft. On backends where logits change with batch shape or memory layout (Vulkan), that re-verification can reject a token the original verification accepted; the rejection restores the same checkpoint and replays again, and the slot loops on one position without emitting anything. qwen35moe with --spec-type draft-mtp stalled this way a few hundred tokens into long generations (the v0.6.8 MTP hang): the loop repeated "accepted 2/3, restore at pos 995" every 27 ms with the GPU at 90 percent. Accept the replayed tokens without re-verifying and sample only the continuation from the final position. The replayed prefix was accepted by the verification that triggered the restore; the replay exists to rebuild state. On backends with batch-shape invariant logits the re-verification always agreed, so behavior there is unchanged (verified bit-identical on CPU with and without this change, 800-token greedy pair, 118 restore rounds).

Originally by Gaetan Puleo (llama-cpp-nathan-toolbox-deepseek-v4-poc, branch deepseek-v4-flash-strix-halo); cherry-picked with the mmid hunk dropped. --- ggml/include/ggml.h | 5 + ggml/src/ggml-vulkan/ggml-vulkan.cpp | 170 ++++++++++++++++++ .../vulkan-shaders/flash_attn_top_k.comp | 144 +++++++++++++++ .../vulkan-shaders/lightning_indexer_cm.comp | 125 +++++++++++++ .../lightning_indexer_decode_cm.comp | 110 ++++++++++++ .../lightning_indexer_scalar64.comp | 92 ++++++++++ .../vulkan-shaders/vulkan-shaders-gen.cpp | 7 + ggml/src/ggml.c | 14 ++ src/llama-graph.cpp | 7 +- src/llama-graph.h | 4 +- src/models/deepseek4.cpp | 2 +- tests/test-backend-ops.cpp | 10 +- 12 files changed, 686 insertions(+), 4 deletions(-) create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/flash_attn_top_k.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/lightning_indexer_cm.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/lightning_indexer_decode_cm.comp create mode 100644 ggml/src/ggml-vulkan/vulkan-shaders/lightning_indexer_scalar64.comp diff --git a/ggml/include/ggml.h b/ggml/include/ggml.h index f0eda79a1ae2..2ff12d00295d 100644 --- a/ggml/include/ggml.h +++ b/ggml/include/ggml.h @@ -2486,6 +2486,11 @@ extern "C" { struct ggml_tensor * a, struct ggml_tensor * sinks);

Perf cases sweep kv 8k/32k/64k at nb 1/8/64/512 with a fixed active set. Measured on gfx1151: the sparse shader is flat vs kv at prefill (~2.2 TFLOPS active-only) while nb < 64 falls back to dense and scales with kv (1326 us at 64k, nb=1) - the gap a sparse decode path needs to close.

This adds a gather pass (flash_attn_gather.comp): copy the active rows (dense prefix + top-k selection; MQA, so all 64 query heads share one set) plus their mask values into a compact contiguous scratch in prealloc_y, then run the ordinary dense FA over the compacted K/V/mask. V is the K latent, so one gather serves both. Invalid indices and padding get zeroed K and -inf mask. The FA function itself only has its inputs swapped: KV, mask geometry, strides and the K/V/mask bindings are overridden up front and every downstream decision (pipeline choice, split-k, workgroup sizing, use_mask_opt) sizes itself to the compact KV unchanged. Engages for the V4 CSA decode shape when kv >= 2x the padded active set; GGML_VK_FA_TOPK_GATHER=0 disables. Measured (gfx1151, test-backend-ops perf, active set 1536): kv=8192 nb=1: 255.6 us -> 55.8 us (4.6x) kv=32768 nb=1: 986.4 us -> 56.1 us (17.6x) kv=65536 nb=1: 1333.8 us -> 58.7 us (22.7x) Time is flat vs context. nb>1 still falls back to dense pending a union gather. FLASH_ATTN_EXT eval suite green incl. the top-k parity cases (the kv=4096 nb=1 case exercises this path end-to-end vs CPU). Co-Authored-By: Claude Fable 5 Fold-in note for the toolbox branch: use_dequant_kv is additionally gated on !fa_compact.active (the compact scratch is already contiguous f16, and the two scratch layers must not stack), and the compact stride overrides chain through the toolbox's nb*_eff values so the contiguize/dequant path keeps its strides when the gather is inactive.

Same launch geometry as the CUDA kernels; plain f32 compute, no subgroup or coopmat requirements, so the pipelines are created unconditionally. The value at decode is dispatch-count collapse: the unfused fallback runs the decomposed graph (measured on gfx1151 config-a partial offload: SUM_ROWS alone 79 dispatches x 39.7us = 3.1ms per graph, plus DIV/MUL/ ADD shares at 4x4 shapes) where the fused form is 3 dispatches per layer. resolve_fused_ops now keeps all three fusions enabled on Vulkan instead of printing 'not supported, set to disabled'. Parity: upstream test-backend-ops DSV4_HC_PRE/COMB/POST cases green vs CPU on first build.

Relative to the old scalar path, throughput improved 85.9%, total Vulkan time fell 46.3%, and sparse FA time fell 86.4%. + +The main unresolved tradeoff is scratch memory. At PP2048, the two output partitions use about 539 MiB because each stores an f32 partial output for 512 dimensions x 64 heads x 2048 queries, plus L/M data. The device maximum storage-buffer range is checked and the code falls back when the allocation is unavailable. The path is temporarily default-on for a llama-server coherence test but should not be finalized without discussing this footprint. A likely next step is to avoid materializing both full output partitions, for example by directly merging the selected partition into the raw result or processing query tiles, while retaining the measured split-path speed. + +The old sparse selection heuristic required `total_k >= 3 * active_k`. For the coherence test it now selects sparse attention whenever `total_k > active_k`; equality still uses dense FA because no keys are pruned. The shape, capability, and allocation gates remain unchanged. + +Prototype logs: + +- `/tmp/dsv4-fa-exact-qk.log` +- `/tmp/dsv4-fa-exact-softmax.log` +- `/tmp/dsv4-fa-exact-full.log` +- `/tmp/dsv4-fa-exact-split.log` +- `/tmp/dsv4-fa-split-correctness.log` +- `/tmp/dsv4-fa-all-correctness.log` +- `/tmp/dsv4-vulkan-split-32k.log` + +## Llama-server coherence check + +After making the split path default-on and changing the sparse crossover to `total_k > active_k`, `llama-server` produced a coherent response from a 2,044-token prompt at significant context depth.

All three are inert at a single sequence, so the existing tests never reached them. - flash_attn_top_k_cm.comp wrote the L/M rows at a base that omitted the stream count. The split buffer is [O matrices][L/M rows] with both regions spanning ne3, so with more than one sequence the selected partition's L/M landed inside the O region and corrupted partition 0. - The mask's per-stream offset stepped by nem1 * KV. That assumes the mask row length equals KV, which the split path breaks: it overrides the mask stride to the full K range while KV covers only the raw prefix. Separate the two quantities - m_stride is the row-to-row step inside the tile (0 under GQA), m_row_len is the mask's real row length used to step between tokens and streams. They coincide everywhere except GQA and this path. - Query tiling conflicts with multiple streams: flash_attn_split_k_reduce takes the tile height as ne2 and derives the destination row from it, so with several tiles it writes stream s at s*tile_size instead of s*N. Tile only when there is one stream, which is the prefill case the tiling was added for.

Use the decoded globals init_indices() already computes, so routing the split path at a sibling shader fails loudly instead of writing at wild offsets. - Drop profile_stage and GGML_VK_FA_TOPK_PROFILE. This also removes two continues from the sparse kernel's key loop. - Remove the unreachable mask-stride override branch (nothing sets bits 16..30 without bit 31) and restore the comment explaining why the GQA case writes zero the roundabout way: the compiler must not fold it, or stride alignment detection breaks. - Assert that the mask stride covers the raw KV range. The raw dispatch smuggles that stride through split_kv, which the shader also uses to derive its KV range, so a stride below KV would silently clip it. - Request descriptor sets only after the split scratch is known to fit, so the fallback path does not inherit n_tiles of unused requests. - n_head_log2 is unread with max_bias == 0; pass 0 rather than a number that looks computed. - Make the crossover depend on the path that will run. The coopmat sparse path wins as soon as any key is pruned, but the scalar fallback does not and regresses against dense FA until the pruned fraction is large, so it keeps its original 3x margin. - Record that the coopmat sparse shader requires 64-wide subgroups and eight of them, at the constants that encode it.

Add an ns parameter and three cases: two at ns=2 (with and without sinks, single tile) and one at ns=3 with 300 query tokens, which also crosses the 256-token tile boundary. The per-token selection is offset by the stream so a dropped stream stride reads another sequence's keys rather than the same ones. All three fail on the unfixed shaders and pass with them fixed.

Give the reduce a separate dst_ne2 and use it for the destination index only. Ordinary FA split-K passes ne2 for it and is bit-identical. The sparse path passes the full batch, so tiling is unconditional again. This matters for memory, which is the binding constraint on this model. The scratch is capped at 256 queries per tile rather than scaling with the batch, so at ub2048 a 2-sequence context drops from 1028 MB to 128.5 MB and a 4-sequence one from 2056 MB to 257 MB. It also removes a cliff: 8 sequences at ub2048 would have exceeded maxStorageBufferRange and silently fallen back to the slower non-split kernel. Sparse FA timings are unchanged (every shape within 0.45%, inside run-to-run spread). 13,308 FLASH_ATTN_EXT cases pass, which covers the ordinary split-K path that shares this shader.

From 2a6d1de4376204749f8cfd4a80eb50c57c2fdb83 Mon Sep 17 00:00:00 2001 From: Nathan Wilson Date: Thu, 13 Aug 2026 16:00:20 +0000 Subject: [PATCH 115/212] vulkan: extend DeepSeek V4 gather-to-compact to small batches The gap and its consequence were diagnosed by Jaap Buurman: the sparse prefill path gates on batch >= 64 and gather-to-compact gated on batch == 1, so batch 2..63 fell through to dense attention over the whole compressed KV, at a cost that grows with context. That is where a speculative draft lands (n_max 3-5), which is why token generation dropped off sharply with DSpark enabled. This implements the fix for that diagnosis. Give each query token its own gathered top-k block rather than deduplicating into a union. No dedup pass, no atomics, and the size is bounded by n_kv_raw + n_batch*n_top_k regardless of depth. Cross-token rows are neutralised through the mask, which already encodes each token's selection: token t reads -inf on any block that is not its own, so the softmax cannot double count. The compact mask is token-major [n_batch][kv_c], which is what the GQA mask path already expects (m_stride 0, rows stepped by gqa_iq1 * m_row_len). Measured on gfx1151, test-backend-ops perf, medians of 2 launches, n_kv_raw=2304 n_top_k=512. Gather cost is flat in depth (894 us at batch 4 at every depth); dense is not: kv rows batch dense gathered speedup 11008 2 2194 us 680 us 3.23x 11008 4 2204 us 895 us 2.46x 11008 8 2217 us 2217 us 1.00x (gate declines: kv < 2*kv_c) 35584 2 7065 us 680 us 10.38x 35584 4 7099 us 895 us 7.93x 35584 8 7114 us 1316 us 5.41x 133888 2 7552 us 680 us 11.10x 133888 4 7971 us 894 us 8.92x 133888 8 8348 us 1320 us 6.32x Batch 1 is unchanged in behaviour and stays on the same code path. Not validated end to end. A deduplicated union would shrink the gathered set further wherever adjacent draft tokens select overlapping keys, and would lift the batch ceiling documented in the following commit.

The parallel Lightning Indexer uses 62720 of 65536 bytes of shared memory at N_WAVES=8 / HEADS_PER_TILE=4, so exactly one workgroup fits per CU. That is the intended trade, but raising either constant overruns the budget and the pipeline then fails to create and silently falls back to the small variant. Write the arithmetic down next to the arrays. The small-batch gather's compact set is independent of context depth but grows with batch, so its attention work is quadratic in batch against dense's linear. The kv >= 2*kv_c gate already caps this at about batch 6 at 32k depth and ~30 at 128k, and beyond the cap dense runs instead, so it is never slower. But the measured speedups do not show that ceiling and it is the main argument for building the deduplicated union later.

Measured on the real model, adjacent tokens share 60% of their selections over 4 tokens and 76% over 8, so the union is materially smaller than n_batch*n_top_k. The size is only known on the GPU, so flash-attention now reads its KV bound from a buffer instead of the push constant, behind a new DYNAMIC_KV pipeline flag. Every other pipeline folds the flag away at compile time and is unchanged (13308 FLASH_ATTN_EXT cases pass identically with the union off). No indirect dispatch is needed: FA workgroup counts come from neq1/neq2/neq3 and never from KV, so only the loop bound moves. Padding the count to 256 keeps KV % Bc == 0, which lets the aligned pipeline variant still apply. Dedup marks a bitmap from the top-k lists and compacts by scanning bitmap WORDS. An earlier version scanned the mask row by row: simpler, but it made dedup cost scale with depth and measured 0.71x at kv=133888, ie a loss. The bitmap form is O(n_batch*n_top_k) to mark and R/32 to compact, and is depth-independent. test-backend-ops perf, medians of 2, n_kv_raw=2304 n_top_k=512, fixture overlap 60% (the default generator produces near-zero overlap and would make the union look worthless by construction): kv batch per-token union speedup 35584 2 680 us 632 us 1.08x 35584 4 892 us 720 us 1.24x 35584 8 1315 us 900 us 1.46x 133888 2 679 us 638 us 1.06x 133888 4 892 us 726 us 1.23x 133888 8 1314 us 909 us 1.45x Union cost is flat in depth (720 vs 726 us at batch 4 across a 3.8x depth range), which the per-token form was not. Opt-in via GGML_VK_FA_TOPK_UNION=1, single stream only, and it falls back to the per-token blocks when the compressed region exceeds the shared bitmap. The kv >= 2*kv_c gate still uses the worst case, so the batch ceiling is NOT yet lifted; doing that needs a GPU-side fallback for an oversized union.

That is the batch ceiling the previous commit documented and did not lift. The union size is only known on the device, and the note on the previous commit assumed lifting the ceiling therefore needed a GPU-side fallback for an oversized union. It does not. The union is bounded by the source, so there is no dispatch to recover from; the missing piece was only a measurement. The union shader now writes its count into a small host-visible buffer and the host prices the next step from it. The read is deliberately unsynchronised and one graph stale -- overlap is a property of the model and the draft, not of one op -- and a wrong estimate costs part of one step, never correctness, because every allocation and dispatch bound is still the worst case. Estimates are held per batch size. A speculative decode varies the batch with the accept count, and the overlap itself varies with the batch (0.64 at 2 tokens, 0.40 at 4, 0.24 at 8), so a single slot would be invalidated on nearly every step. Each estimate tracks the latest measurement, lightly smoothed, and a declined step dispatches the scan in a new count_only mode that writes no index list. Both of those are deliberate and were measured the other way round first. Holding a decaying peak to stay conservative, and sampling the probe every 256 declines to stay cheap, together produced 1992 us on a shape the union runs in 898: the asymmetry actually runs the other way, because an estimate that is too high declines compaction and forgoes 2-3x for as long as it stays high, while one that is too low costs a single step and is corrected by the count that step produces. Sampling makes it worse still, since a decline is exactly the state in which the compact path stops refreshing the estimate, so the stale value stays latched for the whole sampling period. The probe is one workgroup against the ~2.2 ms dense op it rides along with, and it costs 0.2% of a declined step. The same measurement settles the reverse case. Where selections do not overlap, the union is the same size as the per-token blocks and its scan is pure cost, so those now stay on the per-token path rather than being admitted whenever the worst-case gate happened to allow them. test-backend-ops perf, medians of 3 launches counterbalanced A B B A A B, spreads at or under 0.4%, n_kv_raw=2304 n_top_k=512, at kv=11008 (~32k source) which is the shape where the gate used to decline. The fixture's ov is a per-token share, not the union/selected ratio the model was measured by: at nb tokens it yields (ov + (1-ov)*nb)/nb of the selections, so ov=86 is the setting that reproduces the 0.243 measured on DeepSeek-V4-Flash over 8 adjacent tokens, and ov=60 is deliberately more pessimistic than the model. batch overlap before after 8 ov=86 2215.2 us 704.8 us 3.14x 16 ov=86 2227.3 us 841.3 us 2.65x 8 ov=60 2214.5 us 897.9 us 2.47x 16 ov=60 2226.2 us 2231.2 us 1.00x union does not fit, declined 8 ov=0 2213.5 us 2219.0 us 1.00x nothing to deduplicate, declined The union cost is depth-independent as before, so the lifted cells now sit alongside the deeper ones: 897.9 / 900.7 / 906.6 us at batch 8 ov=60 across kv 11008 / 35584 / 133888. Every cell at kv 35584 and 133888 is 1.00x: this changes which shapes are admitted, not how the union performs once admitted. Both declines above are the estimate working rather than failing. At ov=60 and batch 16 the union really is 5888 rows against 11008 source rows and compaction would not pay; at ov=0 there is no overlap to exploit at all. Verified from the executed graph with GGML_VK_FA_UNION_STATS=1, added here, which reports the measured union/candidate ratio and the resulting decision rather than leaving engagement to be inferred from a timing. It reads 0.246 at ov=86 and batch 8, against the 0.243 measured on the model. 13310 FLASH_ATTN_EXT cases pass with the union off and on, including three new overlap cases at the shapes the gate now admits. End to end on a model that has no top-k tensor at all, so the compaction path is never reached and the change should be structurally inert: Qwen3-Coder-30B-A3B UD-Q4_K_XL, same counterbalanced order, medians of 3. pp512 1578.20 -> 1591.67 t/s and tg32 96.89 -> 97.28 at d0; pp512 700.64 -> 699.32 and tg32 53.92 -> 54.45 at d16384. All within 1%. The union path itself cannot be checked this way: it needs batch 2..63 decode, which only a speculative draft produces. Still measured against a synthetic fixture rather than real draft tokens: that needs a runnable target and draft pair, which this box cannot host.

With the draft now drivable, the proxy turns out to have been optimistic, and the correction runs against that commit's own message. DeepSeek-V4-Flash UD-IQ3_XXS with the DSpark draft, Vulkan attention and CPU experts, 25538 tokens of context. The gate reports union/candidate 0.560 and 0.609 on the target layers and 0.484 to 0.651 on a second shape (n_kv_raw 256, most consistent with the draft's own sparse attention, also GPU-resident). Mean about 0.56 at batch 4, against 0.397 from the proxy at a window of 4. Draft tokens diverge from each other more than adjacent prefill tokens do, which is what a draft exploring rather than committed text should look like. The fixture's ov maps to (ov + (1-ov)*nb)/nb, so ov=60 predicts 0.55 at batch 4 against 0.56 measured: ov=60 reproduces real drafting almost exactly. The previous commit says ov=86 is the setting that reproduces the model and ov=60 is deliberately pessimistic. That is backwards for real draft tokens, and the realistic headline at batch 8 is 2.47x rather than 3.14x. The kernel numbers in that table are unchanged and still correct for the overlap each column states; only which column describes reality has moved. Batch 8 overlap itself is still not measured on real drafts, for the reason below, so 2.47x is an extrapolation from batch 4. The path does engage: 56 of 57 sampled gate decisions took the union, and the single decline is the unseeded first call, which then probes. That is the designed bootstrap, observed on the real model rather than a fixture. Scope, stated plainly because the previous commit implies more: DSpark drafts 3 tokens, so the batch is 4 and --spec-draft-n-max does not raise it, an MTP head having a fixed width. At batch 4 and this depth kv_c is 4352 against n_kv 8704, so the OLD worst-case gate admits too and the gate change makes no difference there; the smaller compact set comes from the union commit. For this target and draft the gate change buys a lower depth threshold instead: roughly 21.0k tokens rather than 25.5k on the target layers, and 11.8k rather than 17.7k on the second shape. The 2.47x and 2.65x cells need batch 8 or 16, which this pair does not generate. GGML_VK_FA_UNION_STATS takes a period now rather than being fixed at 256, and reports running totals. The fixed period is why this took two runs: a 64-token speculative decode over 25k of context emitted exactly ONE line, which reported only that the first call was unseeded. A diagnostic whose sampling rate can hide the thing it exists to measure is not a diagnostic. Measurements and provenance: ~/strix-results/derived-dsv4-union-gate-20260814.md section 9.

GGML_VK_FA_TOPK_UNION=1 was the odd one out because it began as a prototype, and it is no longer one. What makes it safe to default is that the path declines itself rather than needing a user to know when to avoid it. Where the selections do not deduplicate, the estimate says so and the per-token form runs instead; where the compact set would not fit under the gate, dense runs. Both were measured, at 1.00x, rather than assumed. Kept as one commit of its own rather than folded into the gate change, because it is a policy change and not a mechanism one: reverting these four lines restores opt-in behaviour without touching the gate logic, which is what a bisect would want if a regression turns up. 13310 FLASH_ATTN_EXT cases pass with the variable UNSET, which is the configuration this changes and the one that ships. That is the same code path as the previously validated GGML_VK_FA_TOPK_UNION=1, but it was run again rather than argued from equivalence.

Two community test sets were run that way before anyone noticed, which is what prompted this. The restriction was incidental rather than essential. The gather RELOCATES rows; it never reads a value out of one. Addressing K as raw 4-byte words instead of f16 elements makes the same shader serve any type whose row is a whole number of words, which every block-quantised type here satisfies at head size 512. The union shader needed no change at all - it only ever touched top_k indices. Zeroing an unused row now writes zero BYTES. That decodes to zero for the block-quantised types as well as for f16, because a zero scale zeroes the block; those rows are -inf in the mask regardless, so zeroing only keeps a garbage dot product out of the softmax as a NaN. The type gate asks ggml_vk_fa_kv_native rather than just "is it quantised". While the compact scratch is active the dequant/contiguize pass is disabled by construction, and the assert guarding that combination aborts rather than falling back, so admitting a type flash-attention has no native shader for would crash instead of degrade. test-backend-ops perf, kv=11008 n_kv_raw=2304 n_top_k=512 ov=60, gather off vs on: batch f16 dense -> gathered q8_0 dense -> gathered 2 2192 -> 645 us 3.40x 3917 -> 1110 us 3.53x 4 2203 -> 726 us 3.03x 3924 -> 1257 us 3.12x 8 2213 -> 910 us 2.43x 3936 -> 1567 us 2.51x 16 2219 -> 2232 us declined 3930 -> 3952 us declined Two things worth stating because they contradict what I expected going in. Compaction does NOT pay more on quantised K/V. The reasoning was that a gathered set is contiguous and would dodge the strided-read and channel-aliasing taxes that hurt quantised reads more; the measured ratios differ by 3 to 4%, inside noise. It pays the same proportion from a worse starting point. That worse starting point is the real result: q8_0 attention is about 1.78x SLOWER than f16 here, dense (3917 vs 2192) and gathered (1110 vs 645) alike. Halving the bytes does not pay for the dequant work in the inner loop at this head size. So this change makes q8_0 K/V survivable for DSv4 rather than advisable - f16 is still the faster cache by a wide margin, and that inverts the usual q8_0-KV-buys-speed rule of thumb for this model. 13318 FLASH_ATTN_EXT cases pass, including 8 new q8_0/q4_0 top-k cases at the shapes a DSv4 decode actually hits. test_flash_attn_ext_top_k takes a type_K parameter for them.

Measured, that costs 0.15 us per KV row attended - 0.1481 / 0.1510 / 0.1512 us/row at batch 8 / 4 / 2 and 0.1565 dense, so a constant across a 3.6x span of row counts and across both regimes. It is what made q8_0 attention 1.78x slower than f16 while reading half the bytes. The gather is the natural place to pay it instead: it already touches every selected row exactly once. Decoding there makes the compact scratch f16, flash attention takes its f16 path, and the redundancy disappears.

Flash attention picks its pipeline from what the SCRATCH holds, not from the source tensor, so k_type_eff/v_type_eff now also key off the compact state - the same mechanism use_dequant_kv already used, which is why that variable existed in this form. q8_0 only, deliberately. It is the type both community test sets used and the one worth having; every other quantised type keeps the verbatim path, which is correct for them and validated. Generalising means one shader variant per type through dequant_funcs.glsl, which is only worth the shader-permutation cost if this shape of win reproduces elsewhere. Not covered: the per-token gather still relocates verbatim, so a batch where the union declines but the per-token form fits keeps paying the inline decode. Same fix applies, and the same measurement will say whether it is worth a second shader. 13318 FLASH_ATTN_EXT cases pass.

Its inline-decode penalty is the same shape - a constant per KV row attended, flat across batch and across dense vs gathered - but larger: 0.172 to 0.179 us/row against q8_0's 0.148 to 0.153. Unpacking nibbles costs more ALU than the halved bytes save, which is also why q4_0 was the SLOWEST of the three types before this. kv=11008 n_kv_raw=2304 n_top_k=512 ov=60, batch 2 / 4 / 8 type dense verbatim gather decoded gather f16 2192/2203/2213 - 640/726/902 q8_0 3917/3924/3936 1110/1257/1567 628/712/888 q4_0 4134/4141/4145 1189/1342/1671 626/711/886 All three converge, because after the gather they run the same f16 attention; what is left is the scattered-read side, where fewer bytes now wins. Against the dense fallback each type took before any of this work, batch 8 is 2.45x for f16, 4.43x for q8_0 and 4.68x for q4_0. The interesting part is what the first attempt got wrong. Generalising via dequantize4() from dequant_funcs.glsl looked obvious and passed on q8_0, then failed q4_0 with NMSE 1.17. That helper is permutation AGNOSTIC by design: mul_mat_vec only ever feeds it into a dot product, where any consistent element order gives the same sum, so for q4_0 it returns nibbles in packed order rather than element order. q8_0 passed only because its layout happens to be contiguous. Materialising a row into memory is precisely the use where the order matters, so each type's true mapping is now written out - for q4_0, byte j carries element j in its low nibble and element j+16 in its high one, exactly as dequant_q4_0.comp materialises it. That is also why this stops at two types rather than looping over the whole native list: every type needs its mapping stated and tested, an #error guards anything else reaching the shader, and q8_0 and q4_0 are the two actually used as a KV cache. q4_1/q5_0/q5_1/iq4_nl keep the verbatim gather, which is correct for them. 13318 FLASH_ATTN_EXT cases pass, including q4_0 and q8_0 top-k cases at the shapes a DSv4 decode hits, plus q4_0 perf cells alongside the q8_0 ones.

Half as many, twice as wide accesses were still 6% slower on the smallest op the gather serves. Bisected over the 19 beta3 commits with the tip's test file overlaid at every point, so the instrument stayed fixed while beta3 grew its own perf cases. nb=1 at kv=8192: 54.58 us at the pre-beta3 base, flat through commit 16 (54.84), 58.24 at 6b2cade31, 58.23 at the tip. Step 4*LANES instead. Each access stays contiguous across the lanes, so coalescing is unchanged, and an f16 row at head size 512 is 256 words == 4*LANES: one iteration, no loop overhead. The tail loop carries the quantised row sizes, which are not multiples of 4*LANES (q8_0 is 136 words, q4_0 is 72). nb=1 against the pre-beta3 base, f16 K/V: -0.07% at kv=8192, -2.83% at kv=35584, mean -1.29% across the six shapes, so the regression is gone rather than reduced. Against beta3 as merged: -4.8% to -6.2%. The nb>=2 gains are untouched, worst cell -0.51%. 13318 FLASH_ATTN_EXT cases pass. Worth noting the gather itself was never the cost at nb=1: with GGML_VK_FA_TOPK_GATHER=0 that cell is 249.84 us against 58.14 us with it on.

A 128GB community run measured it end to end: prefill -5.4/-22.2/-39.4/-52.9% against f16 at source depths 17k/33k/67k/134k with -ctk q8_0. The sparse shaders stay f16-only. A quantised cache is dequantised once per op into the prealloc_x f16 scratch by the dense path's own fused dequant+transpose pipeline, and the shaders read the scratch. K and V are the same tensor in this path, so one pass covers both at half the dense path's scratch footprint. Types without a dequant-transpose pipeline, oversized caches, and GGML_VK_FA_DEQUANT=0 keep the dense fallback. test-backend-ops perf at nb=1024, kv 5504/11008/19200/35584 (the community depths in compressed-K rows): q8_0 was 60.9 -> 427.6 ms dense (1.30x -> 8.27x of f16, growing with kv) and lands within +0.8% of f16's flat 46.9-51.7 ms with the scratch; the dequant pass itself costs under 1%. 36/36 FLASH_ATTN_EXT top-k cases pass, including 6 new quantised prefill cases (nb=64 ns=1/2, nb=128 split form).

Their per-kernel table - 43.8 us scalar against 27.9 us small CM per 1k scanned rows at batch 5, and the same ratio at every depth - is what showed the indexer's cost is a per-tile constant rather than anything to do with tokens or bytes. Once the cost is per tile, the thing to minimise is the tile count, and that is what this changes. The finding is downstream of their work; only the choice of shader differs. The decode CM shader puts 16 HEADS in the coopmat N dimension and dispatches one workgroup per token, so it issues 4*n_batch tiles per 16 KV rows. That is the arithmetic minimum - (64 heads x n_batch tokens) / 16 columns - because 64 heads fill its 16 columns exactly, with no remainder at any batch. The small CM shader puts 16 TOKENS in N and pays a flat 64 tiles however small the batch is, so at batch 5 eleven of its sixteen columns are padding. Measured cost tracks tile count: at kv=131584 batch 1 costs 1.95 us per 1k scanned rows and batch 5 costs 26.28, i.e. 13.5x for 5x the work, and both shaders sit at 6.6-7.8 ns per tile. The decode CM shader body has no n_batch == 1 assumption - token is gl_WorkGroupID.y and it indexes q/w/mask/dst by it - so the old gate was an artefact of where it was written. gfx1151, kv=131584 (526k source tokens), us/run, shipped vs this: batch 2 2335.6 -> 419.0 (5.6x, was on the scalar path) batch 3 3492.3 -> 631.8 (5.5x, was on the scalar path) batch 4 3267.9 -> 840.8 (3.9x) batch 5 3465.6 -> 1119.4 (3.1x) <- DSpark n-max 4 verify shape batch 8 3704.9 -> 1764.1 (2.1x) batch 15 4467.9 -> 3231.6 (1.4x) Batch 16 and 32 are unchanged, which confirms the arms are isolated. PR #6's route is kept as the opt-out arm rather than deleted, and is promoted from opt-in to default-on so that one variable is enough to reach it: default decode CM for the whole 2-15 window ..._DECODE_CM_BATCH=0 small CM for 4-15, scalar for 2-3 (PR #6) ..._DECODE_CM_BATCH=0 SMALL_CM=0 scalar for 2-15 (pre-PR #6 baseline) Verified all three route as documented and pass 29/29. Keeping it is not just courtesy: the tile-count argument is hardware independent, but decode CM re-reads the K tile once per token and that part is bandwidth dependent, so the crossover need not sit in the same place on other devices, and these numbers are from one gfx1151 box. A (head, token) packing shader was also tried and is strictly worse - it reaches 4b tiles only when the batch divides 16, and it divides the workgroup count by the batch. Kept out of tree. Numerics: decode CM sums the 64 heads in tiles of 16 rather than one at a time, so f32 accumulation order differs from the small CM path. Cleared by KLD A/B on trunc10 (-c 8192, -b/-ub small so every indexer dispatch routes through the window, 8 chunks wikitext-2, same binary, only the env var differing): -ub 8 mean KLD 0.000000, max 6.0e-5, RMS dp 0.000%, same-top 99.994%, PPL 10507558.3156 identical in both arms -ub 5 mean KLD 0.000000, max 8.8e-4 but 99.9% 4.9e-5 (one tail event, no argmax flip), RMS dp 0.000%, same-top 100.000% Same class as PR #6's own measured numbers (max 5.5e-5, same-top 100.000%) and 45x tighter than the FA_WAVE32 change already shipped. Adds the eval coverage the 2-15 window never had (batches 4/8/15 at kv=256) and the perf grid these numbers came from.

Qwen3.8-Flash-Next (qwen4_exp, released today) carries the same indexer at nh=4. N_HEAD becomes specialization constant 1, one pipeline per supported head count (LI_NH_VALUES = {4, 32, 64}), selected by q->ne[1] at dispatch. It must be a specialization constant, not a push constant: the head loop's trip count has to stay visible to the compiler - as a push constant the loop cannot unroll and decode costs ~55% (measured, gfx1151, kv=131584, and why this commit is not the simpler design). nh=4 does not fill a 16-wide head tile, so the tail tile stages q as zeros (relu(0)*w = 0, padded heads drop out of the sum) and the weight read clamps its index. Both guards are gated on N_HEAD % TILE != 0, a specialization-constant expression, so at nh=64 they fold away at pipeline compile and the codegen is equivalent to the previous shader - measured, because relying on the compiler to range-prove head < N_HEAD instead still cost ~45%: kv=131584, us/run before after decode b1 226.8 219.6 decode b5 1058.8 1007.4 decode b15 3174.0 2966.8 prefill b16 2329.2 2230.2 prefill b2048 281540.5 281169.1 No regression at nh=64; the small decode improvement is within a cautious reading of run-to-run variance and is not claimed. test-backend-ops LIGHTNING_INDEXER: 44/44, up from 29/29 - the suite's existing nh=32 cases had been silently reporting "not supported" under the old gate and now run against the CPU reference. Head size stays pinned at 128: the coopmat tiling and f16vec4 staging both assume it, and every known indexer model (DSv4, GLM-DSA, Qwen4-exp) uses 128.

Hypothesis: RDNA3.5 WMMA is wave32-native, so RADV may lower KHR_coopmat better at wave32 than at the reported default of 64. Mechanics: the cm1 path in mul_mm.comp derives its warp grid from the real subgroup (warp_i = gl_SubgroupID, tiw = gl_SubgroupInvocationID) while NUM_WARPS = BLOCK_SIZE/WARP (spec constants) sizes coopmat_stage[] and ballots_sh[] and warp_r/warp_c assume NUM_WARPS == (BM/WM)*(BN/WN). Forcing sg32 with WARP=64 would over-run those shared arrays and leave warp_c outside the tile, so the gate (a) sets WARP=32 in shadowed copies of the s/m/l mmid warptiles (composes after the BM64/M128 shadows) and (b) halves WM (or WN, keeping WM>=TM, WN>=TN) until the doubled subgroup count exactly tiles BM x BN again, asserting both invariants. BLOCK_SIZE is kept, so workgroup shape, load loops and shmem match the wave64 stack; per-lane accumulator footprint is also unchanged (half the lanes per subgroup, half the (WM/TM)*(WN/TN) fragments). The required size is passed via a scoped CREATE_MM redefinition adding a trailing required_subgroup_size arg (fp16-branch pattern), gated on subgroup_size_control covering 32 since ggml_vk_create_pipeline_func silently drops the required size otherwise.

The neighbouring n picks a different J and passes, which hides it. The existing quantized cases stop at n=129 and the general MUL_MAT set jumps 64 -> 4096, so nothing lands on 256 or 512 and the whole class went untested. Sweep n over 255/256/257/511/512/513 for q8_0, q4_0, q4_K, q5_K and q6_K, in both MUL_MAT and MUL_MAT_ID. On an RDNA3.5 build that runs the J128 kernel with 16 wave32 waves over a 128-row tile these fail for every n that selects J128 and pass at n=513, which selects J112. A build predating that config passes the whole sweep.

The coopmat2 pipeline creation block was left passing a literal 5, so two things go wrong there: - the pipelines are created with 5 descriptors while the shader declares 6 - PARAMCOUNT == mul_mat_id_param_count doubles as the "this is mul_mat_id" argument to ggml_vk_mul_mm_cm2_spec, so it went false and every coopmat2 mul_mat_id pipeline was specialized as a plain matmul, dropping the trailing spec constant Only reachable where device->coopmat2 is true. gfx1151 does not take that path and the v0.5 release predates the constant bump, so neither is affected. Not validated on hardware - no coopmat2 device here. The block does compile: built with the pinned shaderc (GL_NV_cooperative_matrix2 supported). The two OCP FP4 sites stay behind GL_EXT_float_e2m1, which that glslc does not support.

The wave32 gate keeps its subgroup_size_control device guard, so devices without a 32-wide subgroup mode are unaffected. GGML_VK_MMID_TILE16 stays opt-in (documented negative on gfx1151).

GGML_VK_MMID_WAVE32 already exploits this for mul_mat_id and leaves the dense pipelines at the driver default; this gives dense the same treatment, gated on measurement rather than a flag. BLOCK_SIZE is kept, so the subgroup count doubles and WM (or WN) halves until the warp grid tiles BM x BN again. Only the quantised tiles are retiled: on gfx1151 a standalone MUL_MAT microbench at both dense FFN shapes reads q6_K +5.2..+10.8%, q8_0 +5.4..+8.4%, q4_K +0.7..+9.1%, q4_0 -1.5..+1.8%, while f16 reads -6.7..+6.4% and bf16 ~0 - the float paths are bandwidth-bound on the weight stream, not issue-bound. The win tracks inline dequant instruction count (q6_K 3907 -> 3433 instructions, identical 192 VGPRs and 8 subgroups/SIMD). The required subgroup size is now the tile's own WARP for every dense coopmat pipeline. The cm1 shaders derive their warp grid from gl_SubgroupID and size shared arrays as NUM_WARPS = BLOCK_SIZE / WARP, so WARP and the real subgroup must agree; leaving that to the driver made the agreement incidental. Scoped to AMD coopmat1 on a wave64 default; other vendors keep the driver default. GGML_VK_DENSE_WAVE32=0 disables, =2 also retiles the float tiles. Qwen3-32B Q6_K_XL pp2048 +7.2% at ub256 / +3.9% at ub2048, Qwen3.8-27B +5.3% / +4.8%. PPL unchanged: 6.9496 +/- 0.24246 in both arms, all 20 per-chunk values identical, since the retile changes which warp owns an output sub-tile and not the K-reduction order within an element.

GGML_VK_CONCAT_TRANSPOSE: delta-net does ggml_transpose() into a dim-0 ggml_concat(), which the generic concat reads fully de-coalesced. Route that shape through a 32x32 shared-memory tile transpose. CONCAT 11877 -> 957 us/op. GGML_VK_MMID_SCALE_EPILOGUE: apply the following MUL's per-(expert,token) broadcast scale as mul_mat_id writes out, removing a 134 MB write plus read back. Prefill only; the existing fusion is gated to mat-vec. Not implemented in the coopmat2 shader, so it is refused there. GGML_VK_FUSE_UNARY_MUL: silu(x)*y is two nodes in the delta-net path; run it as the existing swiglu split. 750 -> 443 us/op. GGML_VK_MMID_WG256: the RADV tuning gives the dense large tile 256 threads on a 128x128 tile but left the mul_mat_id variants at 128.

Longer splits mean every cross-backend input copy is materialised at the split's start and stays live to its last use inside it, which raises the peak the compute-buffer allocator has to cover - n_copies times over under pipeline parallelism. Only multi-backend configurations can reach this. Keep the growable array, which is what fixes the original >30-input assert, and cut on the constant again as before #22789. >= rather than == so the check keeps firing for splits that did have to grow.

Default settings were not affected; the opt-out was. Snapshot the dense tiles before the wave32 rewrite and build the mmid tiles from the snapshot. When the mmid wave32 pin is not applied, assert the coverage invariant and require the tile's own WARP as the subgroup size where the driver honours it, so the two can never disagree.

The 3-D shape therefore carries no information past the mul_mat, but it does decide how the mul_mat is dispatched: src1 with ne12 = n_seqs is a batch of n_seqs matmuls of ne11 = n_seq_tokens columns each, and every one of them re-reads the whole ssm_out weight. Reshaping to [d, n_seq_tokens*n_seqs] instead gives a single matmul of ne11 = n_seq_tokens*n_seqs columns over one weight read. Mathematically identical: mul_mat is per-column, attn_out_norm is contiguous (the 3-D reshape already required that), and the columns are in the same order in both layouts, so the flattened call computes the same columns in the same order. The reshape_2d after the projection becomes shape-preserving. At n_seqs = 6 this is the difference between a batched call and six unbatched ones on every backend, over 48 of these projections per decode step on the 27B models. Note this only helps n_seqs > 1: one sequence with n_seq_tokens speculative tokens already arrives as a single ne11 = n_seq_tokens matmul. Only qwen35 and qwen35moe are changed, the architectures this was tested on.

The logits are compared with a context without graph reuse (bit-exact), one with n_rs_seq = 1 and one that decodes one sequence per ubatch. It uses fresh random weights at scale 1: at the 0.01 scale of the generated models the recurrent branch does not change the logits, so a wrong state would not be seen. The check runs for qwen35 and qwen35moe, and the test now also runs on the generated qwen35moe model.

For user-facing execution modes and examples, see the +[Snapdragon user guide](README.md#multi-device-execution-modes). + +## Op and Kernel Development Guidelines + +Writing high-performance operators for Hexagon requires following specific guidelines. + +### DDR -> DMA -> VTCM Execution Pipeline + +- Strongly prefer the `DDR -> DMA -> VTCM -> compute (HVX/HMX) -> VTCM -> DMA -> DDR` data flow. +- Direct HVX reads/writes from/to DDR are less efficient and should only be used as a fallback. +- The DMA queue is a strict FIFO where operations must be pushed and popped in strict order. +- Follow the pipelined multi-buffering sequence properly (typically 2x to 16x buffering) so every push has a corresponding pop: + + 1. In the prologue, push initial DDR -> VTCM transfers to prime the pipeline. + 2. In the loop body, wait for buffer N via DMA pop, launch HVX/HMX compute on buffer N, push VTCM -> DDR writeback of result N, + and push DDR -> VTCM prefetch of buffer N+2. + 3. In the epilogue, pop all remaining in-flight transfers to drain the pipeline. + +- Because every push must be matched by a pop, `dma_queue_flush()` is not required when the pipeline sequence is followed + properly. Flushing is only used in rare exceptions where a batch of operations is pushed without individual pops. +- Use the DMA queue interface from [`dma-queue.h`](../../../ggml/src/ggml-hexagon/htp/dma-queue.h) + (`dma_queue_push_ddr_to_vtcm`, `dma_queue_pop`, `dma_queue_push_vtcm_to_ddr`). + See [`cumsum-ops.c`](../../../ggml/src/ggml-hexagon/htp/cumsum-ops.c) and + [`act-ops.c`](../../../ggml/src/ggml-hexagon/htp/act-ops.c) for reference implementations. + +### Avoid Scalar Reads and Writes to VTCM + +- Access VTCM data using DMA transfers or HVX/HMX vector instructions rather than scalar reads and writes. + +### Avoid Scalar Division in Inner Loops + +- Hexagon cores do not have hardware division instructions. +- For recurring divisions across iterations or threads, use `fastdiv` from + [`hex-fastdiv.h`](../../../ggml/src/ggml-hexagon/htp/hex-fastdiv.h) with precomputed divisors (such as + `octx->ctx->mdev.count_div` or `octx->n_threads_div`). +- Do not call `init_fastdiv_values()` for single-use divisions; use standard compiler division (`/`) instead. + +### Host-Side Precomputation via `kernel_params` + +- Precompute tensor shapes, strides, scale conversions, tiling layouts, and validation checks on the host CPU during graph + preparation in [`ggml-hexagon.cpp`](../../../ggml/src/ggml-hexagon/ggml-hexagon.cpp). +- Pack precomputed parameters into the operator's fixed `kernel_params` structure in `htp_op_node` (such as + `htp_mm_kernel_params`, `htp_unary_kernel_params`, `htp_fa_kernel_params`, `htp_get_rows_kernel_params`). +- The NPU executes directly using `octx->kernel_params` without redundant runtime metadata extraction or validation. +- **Strict Host-Kernel Alignment**: + - Verify that parameters calculated by the host CPU are strictly honored by the NPU kernel. + - Ensure the kernel does not ignore host-computed fields (for example, falling back to `octx->n_threads` instead of + using `kparams->n_threads`, or ignoring precomputed `tasks_per_thread` and chunk counts). + - Both human developers and coding agents must audit both sides of the interface: ensure fields populated in `kernel_params` + in [`ggml-hexagon.cpp`](../../../ggml/src/ggml-hexagon/ggml-hexagon.cpp) are actively and consistently utilized by the + corresponding operator entry point and worker threads in `htp/*-ops.c`. + +### Tracing Instrumentation + +- All kernels must include trace events for performance profiling and timeline visualization in Perfetto + ([`hex-profile.h`](../../../ggml/src/ggml-hexagon/htp/hex-profile.h)). +- Surround compute sections with `htp_trace_event_start(tr, HTP_TRACE_EVT_HVX_COMP, (uint16_t) info)` and + `htp_trace_event_stop(tr, HTP_TRACE_EVT_HVX_COMP, (uint16_t) info)`. +- Use specific event types for major phases: + - `HTP_TRACE_EVT_HVX_COMP`: Vector compute execution. + - `HTP_TRACE_EVT_DMA`: DMA transfer wait or poll cycles. + - `HTP_TRACE_EVT_FENCE`: Multi-device fence barrier synchronization. + - `HTP_TRACE_EVT_L2FLUSH`: L2 cache cleaning operations. +- Pass meaningful progress metrics (such as row index, chunk index, or token index) in the 16-bit `info` parameter. + +### Work Queue and Threading + +- Distribute parallel work across NPU worker threads using the thread pool work queue: + + ```c + work_queue_run(ctx->work_queue, worker_func, &op_ctx, n_threads); + ``` + +- Keep worker functions independent and re-entrant. Worker threads should only operate on their designated chunk of rows or elements. + +### Avoid Redundant Defensive NULL Checks + +- Do not add defensive NULL checks or assertions for internal framework pointers or required graph operands and outputs. + Internal pointers include `ctx`, `octx`, local context structs like `*ctx`, `kparams`, and worker callback `data`. +- These pointers are architectural invariants during kernel execution and host-side graph preparation. + Graph compute receives allocated nodes with valid required `node->src[N]` and `node->data` pointers. +- Do not turn an invariant violation into an unsupported operation or missed fusion. + Checks such as `if (!octx || !octx->ctx)` clutter the code, obscure intent, and hide upstream errors. +- **Distinction**: `octx->src[N]` pointers *can* be NULL by design and must be checked when optional. + Examples include attention masks, optional bias or weights in fused kernels, and frequency factors. + +### Multiline Macro Formatting + +- Keep trailing backslashes in multiline `#define` macros cleanly aligned to a consistent column. +- Avoid trailing whitespace after macro backslashes. +- Use [`scripts/snapdragon/ggml-hexagon-align-macros.py`](../../../scripts/snapdragon/ggml-hexagon-align-macros.py) to inspect, diff, + or automatically align macro definitions across Hexagon kernel sources: + + ```bash + # Check for misaligned macros + python3 scripts/snapdragon/ggml-hexagon-align-macros.py ggml/src/ggml-hexagon/htp/ + + # Fix misaligned macros in-place + python3 scripts/snapdragon/ggml-hexagon-align-macros.py --fix ggml/src/ggml-hexagon/htp/ + ``` + +## Multi-Device Partitioning (mdev) + +Multi-device (mdev) mode enables row-level tensor parallel execution across multiple physical NPU cores or virtual NPU +sessions. + +### 128-Byte Cache Line Alignment + +- Shared tensor buffers reside in DDR (RPCMEM) with a 128-byte cache line granularity + (`HEX_L2_LINE_SIZE` = 128 bytes, `HTP_TENSOR_MDEV_LINE_SIZE`). +- **Rule**: Multi-device work partitions must align destination write regions to 128-byte cache line boundaries so distinct + devices never share or overwrite the same cache line. + +### Partitioning Helpers in `htp-tensor.h` + +Common partitioning logic is factored into reusable inline helpers in +[`htp-tensor.h`](../../../ggml/src/ggml-hexagon/htp/htp-tensor.h): + +1.

Find them before recording the merge: + +```sh +MB=$(git merge-base HEAD upstream/master) + +# Files upstream touched that we never touched => upstream change dropped entirely +git diff --name-only $MB upstream/master | while read -r f; do + git diff --quiet HEAD upstream/master -- "$f" && continue + n=$(git diff --numstat $MB HEAD -- "$f" | awk '{print $1+$2}') + [ -z "$n" ] && echo "DROPPED: $f" +done +``` + +Recover each one with `git cherry-pick -x <sha>`. Re-run until the list is empty. + +A file that differs from upstream *and* that we modified is normal fork divergence — review +it by hand, the script cannot judge intent. + +### 2. Record the ancestry + +Only once the audit is clean: + +```sh +git merge -s ours upstream/master -m "Record upstream sync (content applied via #<PR>)" +``` + +`-s ours` creates a two-parent merge commit and keeps our tree **byte-identical** — it +cannot change a single file, so it cannot break the build. Its only danger is burying an +upstream change we failed to apply, which is exactly what step 1 rules out. + +Never run `-s ours` before the audit. + +## Verifying a sync + +```sh +git rev-list --count HEAD..upstream/master # expect 0 +git log -1 --format='%P' HEAD # expect two parents after -s ours +``` From 0636c9aee4a2ab1d38bb7e8c038227c6634c3857 Mon Sep 17 00:00:00 2001 From: "Piotr Wilkin (ilintar)" <piotr.wilkin@syndatis.com> Date: Wed, 16 Sep 2026 19:14:10 +0200 Subject: [PATCH 166/212] pwilkin/strix-halo official merge (#63) Co-authored-by: Claude Fable 5.1 <noreply@anthropic.com> --- common/arg.cpp | 2 + common/speculative.cpp | 6 +- conversion/base.py | 1 + conversion/qwen.py | 3 +- conversion/qwen4exp.py | 9 +- convert_hf_to_gguf.py | 10 + ggml/src/ggml-cuda/conv-tail.cuh | 105 ++ ggml/src/ggml-cuda/dequantize.cuh | 165 ++- ggml/src/ggml-cuda/expand.cu | 63 + ggml/src/ggml-cuda/expand.cuh | 14 + ggml/src/ggml-cuda/fattn.cu | 27 + ggml/src/ggml-cuda/gdn-conv.cu | 163 +++ ggml/src/ggml-cuda/gdn-conv.cuh | 18 + ggml/src/ggml-cuda/getrows.cu | 106 ++ ggml/src/ggml-cuda/getrows.cuh | 4 + ggml/src/ggml-cuda/ggml-cuda.cu | 1000 ++++++++++++++-- ggml/src/ggml-cuda/hyperconn.cu | 176 ++- ggml/src/ggml-cuda/hyperconn.cuh | 6 + ggml/src/ggml-cuda/idx-relu-sum.cu | 25 + ggml/src/ggml-cuda/idx-relu-sum.cuh | 8 + ggml/src/ggml-cuda/mmb-quant.cuh | 336 ++++++ ggml/src/ggml-cuda/mmb.cu | 964 +++++++++++++++ ggml/src/ggml-cuda/mmb.cuh | 27 + ggml/src/ggml-cuda/mmid.cu | 119 ++ ggml/src/ggml-cuda/mmid.cuh | 6 + ggml/src/ggml-cuda/mmq.cu | 14 +- ggml/src/ggml-cuda/moe-weighted-reduction.cu | 149 ++- ggml/src/ggml-cuda/moe-weighted-reduction.cuh | 3 +- ggml/src/ggml-cuda/norm-gated.cu | 134 +++ ggml/src/ggml-cuda/norm-gated.cuh | 14 + ggml/src/ggml-cuda/ple-conv.cu | 299 +++++ ggml/src/ggml-cuda/ple-conv.cuh | 19 + ggml/src/ggml-cuda/qsa-decode-wmma.cuh | 121 ++ ggml/src/ggml-cuda/qsa-decode.cu | 151 +++ ggml/src/ggml-cuda/qsa-decode.cuh | 4 + ggml/src/ggml-cuda/qsa-prefill.cu | 495 ++++++++ ggml/src/ggml-cuda/qsa-prefill.cuh | 4 + ggml/src/ggml-cuda/top-k.cu | 83 +- gguf-py/gguf/constants.py | 14 + gguf-py/gguf/tensor_mapping.py | 9 + include/llama.h | 1 + src/llama-arch.cpp | 6 + src/llama-arch.h | 3 + src/llama-context.cpp | 11 +- src/llama-graph.cpp | 51 +- src/llama-memory-hybrid-idx.cpp | 434 ++++++- src/llama-memory-hybrid-idx.h | 52 + src/llama-memory-recurrent.cpp | 14 +- src/llama-model-loader.cpp | 2 +- src/llama-model.cpp | 39 +- src/llama-model.h | 4 + src/llama-ple-disk.cpp | 158 ++- src/llama-ple-disk.h | 7 + src/models/qwen4exp.cpp | 592 ++++++++-- src/prefix.h | 34 + src/qsa-prefix-state.h | 53 + tests/CMakeLists.txt | 2 + tests/test-backend-ops.cpp | 1030 ++++++++++++++++- tests/test-ple-disk.cpp | 173 +++ tests/test-qsa-prefix.cpp | 41 + tools/llama-bench/llama-bench.cpp | 6 +- tools/server/server-context.cpp | 8 + 62 files changed, 7221 insertions(+), 376 deletions(-) create mode 100644 ggml/src/ggml-cuda/conv-tail.cuh create mode 100644 ggml/src/ggml-cuda/expand.cu create mode 100644 ggml/src/ggml-cuda/expand.cuh create mode 100644 ggml/src/ggml-cuda/gdn-conv.cu create mode 100644 ggml/src/ggml-cuda/gdn-conv.cuh create mode 100644 ggml/src/ggml-cuda/idx-relu-sum.cu create mode 100644 ggml/src/ggml-cuda/idx-relu-sum.cuh create mode 100644 ggml/src/ggml-cuda/mmb-quant.cuh create mode 100644 ggml/src/ggml-cuda/mmb.cu create mode 100644 ggml/src/ggml-cuda/mmb.cuh create mode 100644 ggml/src/ggml-cuda/norm-gated.cu create mode 100644 ggml/src/ggml-cuda/norm-gated.cuh create mode 100644 ggml/src/ggml-cuda/ple-conv.cu create mode 100644 ggml/src/ggml-cuda/ple-conv.cuh create mode 100644 ggml/src/ggml-cuda/qsa-decode-wmma.cuh create mode 100644 ggml/src/ggml-cuda/qsa-decode.cu create mode 100644 ggml/src/ggml-cuda/qsa-decode.cuh create mode 100644 ggml/src/ggml-cuda/qsa-prefill.cu create mode 100644 ggml/src/ggml-cuda/qsa-prefill.cuh create mode 100644 src/prefix.h create mode 100644 src/qsa-prefix-state.h create mode 100644 tests/test-ple-disk.cpp create mode 100644 tests/test-qsa-prefix.cpp diff --git a/common/arg.cpp b/common/arg.cpp index be5f8ebe34bd..3ac2a09c2990 100644 --- a/common/arg.cpp +++ b/common/arg.cpp @@ -2729,10 +2729,12 @@ common_params_context common_params_parser_init(common_params & params, llama_ex {"-lzm", "--lazy-mode"}, "MODE", "on-demand reading of certain tensors, for example per-layer embeddings (default: auto)\n" "- on: read the rows of such tensors from disk on demand instead of keeping them resident (requires mmap)\n" + "- on-direct: like on, but the arch reads the rows with explicit pread()s instead of demand paging the mmap (currently only PLE tables;

Token generation is unchanged in every case (the path only engages from 512 tokens up, so it never runs during decode). The llama layer now opts a model in by architecture through the backend's get_proc_address, so qwen4exp keeps the path it was tuned for and nothing else pays for it. A process that loads several models shares the flag, last load wins; that is noted at the definition. Not measured: qwen4exp itself, for want of a checkpoint on this box.

The compact limits layout becomes [n_seq x blocks starts] ++ [n_tps tails] ++ [n_tps row_idx]. With n_seq=1 this reduces to the original single-seq layout and is byte-identical. Relax qsa_scalar_visibility to accept multi-seq ubatches (one seq per token, no 2-D positions). Disable the scorer trim when a ubatch mixes sequences. Update the prefix fast path to write the tracked seq's row.

Perplexity-neutral on Flash-Next (64 wikitext-2 chunks, paired: dNLL -0.0012 +- 0.0008); every F32 weight of these GGUFs is F16-exact. - producers of MMB GEMM activations (gated norm, SwiGLU, gated attention, HC low-rank scale + SiLU) write the BF16 copy themselves instead of a separate conversion launch. - cont_sigmoid_mul: accept qwen4exp's [head_dim, n_head, T] gate view against the [head_dim * n_head, T] attention output. - ple-conv: fuse the dilated PLE convolution with F32 weights too (UD GGUFs), removing four 80 MB strided transposes per prefill. - tests: UD-Q4_K_XL MoE shapes, MUL_MAT_ID_COLD, HC_COMBINE_NORM_INJECT, CONT_SIGMOID_MUL, CONV_STATE_CHAIN f32w, and perf cases. Flash-Next UD-Q4_K_XL, llama-server, same prompts (t/s): pp2048 775 -> 843, pp16384 920 -> 979 (hot 1062 -> 1182), tg 18.7 -> 22.1.

Without --kv-unified, a ubatch with one slot has one stream, so the loop scanned all LLAMA_MAX_SEQ ids and get_cells(n_stream) tripped the seq_to_stream assert on the first decode past the dense shortcut. Only sched_reserve, whose context reports the cache's stream count, was fixed before. Use the stream count of the indexer cache. Run test-recurrent-state-rollback on the generated qwen4exp model: its non-unified two-sequence replay decodes one slot at a time and aborted here.

A seq_cp that ends inside a block, as the server's child slots do for n_cmpl > 1, leaves a partial shared group and a partial own group there. Neither is complete, so no sequence can select them: from the query that completes the block on, the shared tail of the prompt and the first own tokens drop out of every QSA layer. The masked path maps those cells to the spare block and keeps them visible. Before the multi-sequence change such decodes had several sequences per ubatch and took the masked path. Move the gate into qsa_scalar_visibility_cells (prefix.h) and reject a ubatch when a position block holds one of its sequences under two sequence sets. The check only scans the blocks that hold a shared cell. A seq_cp on a block boundary still takes the maskless path. Also: - accept tokens with several seq ids again; each query reads the row of its first seq id, as the attention mask and the scan already do (qwen4exp with PLE layers rejects such tokens before this point anyway) - check 2-D cells in one pass, only for the sequences of the ubatch Probe on a head-256 variant of the generated qwen4exp model (CPU, block selection on), prompt of 5 tokens, seq_cp, joint decode of both sequences: with the old gate every query from position 7 on selects only cells 0..3; with this gate all cells up to the budget are selected.

The maskless QSA selection of qwen4exp passes no mask, so on the CPU it attended every cell of the window, including empty cells and cells of other sequences. Attend the first n_kv_raw keys plus the unique valid selected keys, in ascending order, as the HIP decode kernel does. With a mask that encodes the same selection the visited keys and their order do not change. The tiled kernel attends every key the mask allows, so a maskless selected-key op takes the per-row path. test_qsa_prefill_maskless now checks the CPU result against its FP64 oracle too. On a head-256 qwen4exp test model the maskless output now matches dense attention exactly while the budget covers every visible cell. With -ffp-contract=off the deepseek4, glm-dsa, deepseek32, qwen4exp (masked) and llama test models give byte-identical attention outputs before and after.

That adds two passes over a tensor the size of the scores for every strip of every QSA layer, also with one sequence, where every query reads the same row. With one sequence, broadcast the row as before. With several, cast the [blocks, n_seq] starts first and gather the F32 rows. Also copy the block cells and the tails to the compute backend once per layer.

Keep the flag in ggml_backend_cuda_context and set it for each backend when llama_context is created, from the model arch. Target and draft now keep their own setting, and the flag is fixed before the first graph, so the graph_optimize BF16 marks and the compute path always agree - pass the context to ggml_cuda_mmb_supported_mm/mmid/glu and ggml_cuda_mmb_claims; mmb_enabled reads ctx.device, not the current device - test-backend-ops never loads a model, so with the default off every ROCm MUL_MAT case and MMB_CONTEXT ran MMQ; opt its backends in so mmb stays covered - drop <atomic>, shorten the measurement comment and say when the opt-in can go Checked here: CPU build of llama and test-backend-ops; clang -x hip --offload-arch=gfx1151 -fsyntax-only of mmb.cu, ggml-cuda.cu, hyperconn.cu and moe-weighted-reduction.cu against Ubuntu's ROCm 5.7 headers (no new diagnostics; the same 2 hipStreamWaitEvent errors from the old headers on both sides); host-side CUDA syntax check of the same files. Not checked: no gfx1151 hardware here, so no test-backend-ops -b ROCm0, no llama-bench and no logits comparison. Needs on Strix Halo: test-backend-ops -b ROCm0 (with MMB_CONTEXT), qwen4exp prefill with and without a non-qwen4exp draft, and a qwen35 prefill to confirm it stays on MMQ.

The decode kernel has no per-query limit (grid y = query); give it a key range per split (chunk) that grows with the query count, so the grid and the partial buffer stay near their 8-query size, and let it take up to 512 queries. qsa_prefill keeps larger ubatches. Up to 8 queries the kernels run exactly as before. Tests: decode cases up to 512 queries (fp64 oracle), maskless decode (WMMA and SIMT, interleaved and not), qsa_prefill cases above 512 queries (poison, 2560 ids, maskless).

On HIP, a synchronous memset or memcpy fails with hipErrorStreamCaptureImplicit while any stream in the process is capturing a graph, in every capture mode including relaxed, and it invalidates that capture too (CHECK_STREAM_CAPTURING in clr). CUDA only rejects this for blocking streams. test-backend-ops -j <n> allocates tensors on one worker while another captures, so with GGML_HIP_GRAPHS every -j run aborted after a random number of cases ("operation would make the legacy stream depend on a capturing blocking stream" from init_tensor, then "operation failed due to a previous error during capture" from hipStreamEndCapture). Upstream master has the same memset and aborts the same way. Use cudaMemsetAsync on cudaStreamPerThread plus a sync of that stream, as memset_tensor and set_tensor already do. Thread-local capture mode would not help: HIP applies the check in every mode. Checked on gfx1151 (ROCm 7.15 runtime), test-backend-ops -b ROCm0 on halo-box master 0fc7226b7: without the fix -j 8 aborted in 2/2 runs, and passed 29800/29800 with GGML_CUDA_DISABLE_GRAPHS=1; with the fix -j 8 passed 29800/29800 in 5/5 runs with graphs on (about 10.5k captures per run), and serial passed 29800/29800. One other serial run failed only ADD_ADD(type=f16,type_addend=f16,ne=[64,5,4,3]) on NMSE 1.03e-7 > 1e-7; that case fails 5/100 runs without the fix and 3/100 on upstream master too.

The qwen35 and qwen35moe MTP graphs compute the draft logits over that head and scatter them into a full-vocabulary row of -inf (ggml_fill + ggml_set_rows). Only the draft changes: the draft cannot propose other tokens, verification is unchanged. The subset is built only when token ids follow BPE merge order, so that low ids are the frequent tokens; otherwise the option is ignored with an error. Probe contexts with unallocated weights skip the build. New field llama_context_params::mtp_draft_vocab (0 = off).

A second context over the same model with mtp_draft_vocab = 0, or a different N, silently drafted over the first context's subset. The subset is now an immutable llama_mtp_draft_vocab obtained with llama_model::mtp_draft_vocab_get(n_keep). The model keeps weak references keyed by (n_keep, buffer type) under a mutex, so contexts that ask for the same N at the same time share one copy, and it is freed with the last context holding it. Each context holds its own reference and passes it to its graphs through llm_graph_params; the MTP graphs use only that one, and graph reuse compares it. llama_cparams::mtp_draft_vocab records the N actually in use (0 when no subset was built: probe contexts with unallocated weights, a tokenizer that fails the merge-order guard, or a model whose MTP block has its own LM head, which now logs a warning instead of building an unused subset).

The QSA fast path adds three host inputs per layer and moves those cuts, which is what made 128..512-token incremental keys disagree with a full re-pool. Optimize still runs per split, but marks live for the whole graph and every split is optimized before any is computed, so carry the remaining reader count forward (mmb_res16_pending) and mark from the split that completes the check.

Mirrors MXFP4 exactly - same block size (32), one UE4M3 scale per 32 values, SRAM_LAYOUT_Q8_1 tiles, q8_0_q8_1 vec_dot kernels (dp4a and MMA data layout), D4 y-side quantizer. Differences from MXFP4: kvalues_rocmfp4 codebook (Codebook10, max level 10 not 12) and the UE4M3 scale decoder without the e8m0 *0.5 factor. Tile rows mirror this master's current MXFP4 config set, incl. the 128/64/128 row. Not added to Blackwell configs on purpose: use_native_fp4 is false for this type there, so it falls through to the Ampere config like NVFP4-generic does. Dual-scale Q4_0_ROCMFP4 (2 scales/block) deferred to a follow-up slice (NVFP4-style per-16 convention).

not in any CMake source list (ggml-hip globs only ../ggml-cuda/*.cu and the template instances) and no callers, so unreachable even from tests. - ggml/rocmfp4/rocmfp4_hip_codebook.cuh - included by nothing; live MMVQ/MMQ paths use get_int_from_table_16 + kvalues_rocmfp4 from ggml-common.h, which already lowers to permb on HIP. The single-nibble perm variant was for an FA K/V decode path not present in this PR. - ggml/rocmfpx/rocmfpx_hip_codebook.cuh - same, included by nothing.

Drop the pascal-dp4a / pascal-older / rdna2 / rdna3 / cdna / rdna4 rows: no hardware to measure there, so those architectures keep today's dequant + BLAS fallback (zero behavior change) instead of an unvalidated tile policy. should_use_mmq now returns false for this type outside the gated set (including Blackwell, which has no rows - native FP4 MMQ is MXFP4/NVFP4-only there), so a missing config row can never reach ggml_cuda_mmq_get_config's abort. --- ggml/src/ggml-cuda/mmq-config-cdna.cuh | 7 ------- ggml/src/ggml-cuda/mmq-config-pascal-dp4a.cuh | 11 ----------- ggml/src/ggml-cuda/mmq-config-pascal-older.cuh | 11 ----------- ggml/src/ggml-cuda/mmq-config-rdna2.cuh | 11 ----------- ggml/src/ggml-cuda/mmq-config-rdna3.cuh | 11 ----------- ggml/src/ggml-cuda/mmq-config-rdna4.cuh | 12 ------------ ggml/src/ggml-cuda/mmq.cu | 10 +++++++++- 7 files changed, 9 insertions(+), 64 deletions(-) diff --git a/ggml/src/ggml-cuda/mmq-config-cdna.cuh b/ggml/src/ggml-cuda/mmq-config-cdna.cuh index 18d9ac6dc698..4a8d89f72019 100644 --- a/ggml/src/ggml-cuda/mmq-config-cdna.cuh +++ b/ggml/src/ggml-cuda/mmq-config-cdna.cuh @@ -166,19 +166,12 @@ static constexpr __host__ __device__ ggml_cuda_mmq_config ggml_cuda_mmq_get_conf // --------------------------------------------------------------------------------------------- CASE(GGML_TYPE_MXFP4, 512, 1, 128, 16, GGML_CUDA_MMQ_SRAM_LAYOUT_Q8_1, MMQ_ITER_K, true, true);

Same targets, same TheRock nightly ROCm, same bundled runtime libraries, same llama-bNNNN-{os}-rocm-{target}-x64.zip assets and bNNNN release numbering. Differences from the original: it builds this repository instead of cloning upstream, falls back to the job token when there is no GH_TOKEN secret, runs the PR trigger only for changes to the pipeline, and gates the self-hosted Strix Halo test jobs behind repository variables so missing runners cannot hold a run in the queue.

Loader validation of those bytes only runs with --check-tensors, so a crafted GGUF decoded differently on GPU and CPU. Guard x > 0x7e -> 0 in both branches to match CPU. Verified bit-identical to the CPU LUT decoder for all 256 scale byte values; nvcc sm_89 compile clean. No behavior change for valid bytes, so existing test-backend-ops results stand.

Only Q8_0 and IQ4_NL have a dedicated fast decoder in mmb_dispatch_quant (the special int constants 1 and 0); every other quant falls back to the generic decode. So the benefit tracks the weight quant type, not the arch. This keeps the path opt-in for all architectures but restricts mmb_quant_type() to the quants that actually have a fast decoder, which removes the regressions PR #75 addressed while keeping the Q8_0 wins.

A maskless ubatch above 512 tokens at any depth past 262140 has no kernel that accepts it, so fattn aborts the instance (#85, and the repeated aborts at k [256,265984,2,1] under -c 524288). Store the union's block ids as uint32 with 0xFFFFFFFF as the sentinel and raise the bound to GGML_QSA_MAX_KEYS = 1048576, the max context the Qwen3.8-Flash-Next card supports with RoPE/YaRN. This replaces the earlier cap-the-gate approach proposed in review on this PR: the fatal band disappears entirely and per-slot context can go past 262140 without falling back to the masked route. - qsa-prefill.cu: ublk becomes uint32 (umask stays uint16: 4 bits per query slot for QSA3_G=4 queries over ratio=4 keys). The descriptor load now reads one uint4 per chunk instead of a uint2 of two packed id-halves; cap is always a multiple of 4, so (g*cap + 4c)*4 stays 16B-aligned. blk_of() tests the sentinel per element; pad slots still resolve to block 0 with no mask bits and are discarded exactly as before. - qsa-decode.cu: depth bound follows the same constant. Its ids are gathered directly (no block packing); the per-row unique table is sized by ids->ne[0] (<= 2560), not by nk, so depth was never structurally limited. - common.cuh: one shared GGML_QSA_MAX_KEYS so the two kernel gates cannot drift apart again; qwen4exp.cpp mirrors it (llama/ must not include ggml-cuda). - qwen4exp.cpp: QSA_MASKLESS_MAX_KV = 1048576 replaces the bogus 16777216, which was checked against neither kernel bound. Verified on the host only: the CPU build of libllama/ggml compiles, test-qsa-prefix and test-qsa-fast pass, and a host harness reproducing the writer/reader lines proves the old and new encodings agree for every id < 65535, that the old one mis-serves 65535/65536/66495 (sentinel aliasing and truncation) where the new one is exact, that padding still resolves to a discarded block 0, and 20000 randomised lists round-trip. NOT run on gfx1151: no ROCm/HIP toolchain here, so the kernel itself is unbuilt and unmeasured. Expect +16 MiB of pool per ubatch at ids=2051, n_q=4096 (uint32 ublk doubles that buffer).
