…org#25047) * server-stream : pimpl * server-stream: prefix free functions with server_stream_ address review from ggerganov: scope the public stream functions under the server_stream_ prefix, matching server_stream_session_manager_start/stop. * server-stream: guard session and manager state with the mutex address review from ggerganov: make done, completed_ts and the GC running flag plain members under their mutex and set the condvar predicates under the lock. keep cancelled atomic for the lock-free should_stop poll. * server-stream: trim comments to the non-obvious address review from ggerganov: drop comments that restate the code, keep the concurrency, lifetime and ordering rationale. de-stale a few comments left by the pimpl: g_stream_sessions is now internal and the /v1/streams listing is gone. * server-stream: update dev docs for the pimpl and prefix reflect server_stream_session_manager_start/stop and the server_stream_ prefix, note the manager is now a file-static singleton hidden in the .cpp * server-stream: move stream traces to debug level keep the bring-up traces for diagnostics but off the default log: skip drain, draining, drain ended, DELETE evict, attach_pipe, and the router stream resume proxy. * server-stream: align router stream resume proxy trace with upstream the child-side bring-up traces are already SRV_TRC on master, move the router stream resume proxy trace to the same level. * server-stream: move stream_read_status enum to the cpp it is only used by the hidden session and consumer types, so it belongs with them behind the pimpl boundary, not on the public header surface. --------- Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>
Improvement of the CI to run on all hip-related changes as a follow-up to ggml-org#25373 so breakage is more likely to be caught in future

…xpert tiles) (ggml-org#25433) * opencl: ragged-tile MoE prefill GEMM (skip padded expert tiles) The MoE prefill GEMM groups tokens into TILESIZE_N=32 per-expert tiles; at low tokens-per-expert most tiles are mostly padding. When a tile's upper 16 slots are all padding (router index 0xFFFFFFFF), skip the second dotx16_reduce8 half. Numerically identical (skipped lanes are padding). Applied to all eight *_f32_ns MoE GEMMs; default on, opt out with GGML_OPENCL_MOE_RAGGED_FP16=0. * opencl: quarter-granularity ragged MoE tile-skip (8-col skip-groups) Replace the two half-tile dotx16_reduce8 calls in the 8 *_f32_ns MoE GEMMs with four dotx8_reduce4 (8-column) calls, skipping each empty trailing skip-group independently. Padding is always trailing, so the kernel rounds the valid count up to the skip granularity and skips fully-padding groups. Byte-identical to the non-skipped path. New env GGML_OPENCL_MOE_RAGGED_GRAN={8,16,32} (quarter/half/ off); default quarter. * opencl: move ragged moe env var in cl_init --------- Co-authored-by: Li He <lih@qti.qualcomm.com>

… of 128. (ggml-org#25464) * opencl: fix garbled output for Q6_K weights with ne01 % 128 != 0 on Adreno Observed with granite-3.1-3b-a800m-instruct, whose vocab is an odd number. Route Q6_K dense mul_mat with ne01 % 128 != 0 off the noshuffle path: decode (ne1==1) uses the correct flat GEMV and the matching GEMM (ne1>1) falls back to CPU (the flat convert has no verified small-batch GEMM kernel for these shapes). All standard hidden/FFN/vocab dims are multiples of 128 and keep the noshuffle path. * opencl: reserve alignment slack for the SOA subbuffer carve in alloc size set_tensor carves quantized weights into per-component subbuffers (d/q, ql/qh/s/d, ...) whose origins are each rounded up to the device base address alignment. When a component's size is not a multiple of the alignment, the carve extends past ggml_nbytes(tensor) and the last subbuffer overlaps the next tensor in the pool -- e.g. q6_K [1536, 49155]: size_s = 49155*96 ends 32 bytes past a 128-byte boundary, so the d subbuffer ends 96 bytes past the tensor's allocation, and whichever of the two neighboring tensors is uploaded last silently corrupts the other (here: the last vocab rows' block scales). This affects any quant type whose component sizes can be misaligned, on any shape with ne01 not a multiple of the alignment granularity; standard power-of-two dims are unaffected. Implement get_alloc_size for the OpenCL buffer type and reserve the worst-case carve slack (4 aligned gaps; 5 components max, q5_K) for quantized tensors. Costs at most 512 bytes per quantized tensor at the observed 128-byte alignment. * opencl: use lm based q6_k mm when ne1 is not multiple of 128 --------- Co-authored-by: Li He <lih@qti.qualcomm.com>
* hexagon: add VISION RoPE support * hexagon: support RoPE on strided half-dim views for all modes * hex-rope: decouple src0 DMA copy size from row stride * hex-rope: support non-contiguous dst for RoPE * hex-rope: fix dst spad pitch for non-contiguous dst
) * cuda: fix snake fusion type predicate, a and inv_b are F32 The matcher required a->type == x->type while launch_snake reads both as const float *, matching the CPU and Metal contract where a and inv_b stay F32. F16/BF16 chains never fused and fell back to the naive path, and a hypothetical all F16 chain would have read F16 bits as float. Aligns the predicate and the comment with ggml-cpu.c * cuda: reject snake fusion on non-contiguous operands The kernel reads x[idx] and a[c] / inv_b[c] linearly, so a non-contiguous view passing the matcher would silently read wrong data. Mirror the contiguity guard already present in the CPU, Vulkan and Metal matchers.
CUDA is compiled with fast math and AMD/HIP is not — this flag lets AMD use fast math too. We can't use -ffast-math: it implies -ffinite-math-only, which won't compile (ggml uses INFINITY for masking) and produces NaNs. -funsafe-math-optimizations gives the speedup without the NaN problems.

…gml-org#24093) A model whose chat template parses at init but fails parser generation at apply time (e.g. uses {% call %}) throws std::invalid_argument from common_chat_templates_support_enable_thinking(), which ran outside the try/catch guarding common_chat_templates_init(). The throw was uncaught and llama-cli aborted (SIGABRT) instead of failing to load. Moved the probe inside that try/catch so an apply-time error fails load the same way an init parse error does.

…ml-org#26165) * common: fix explicit -md precedence over draft sidecar resolution Follow-up of ggml-org#25955, an explicit --model-draft file given with -hfd was silently overridden by the sidecar resolution of the draft repo, and its path was never resolved to a local file. An explicit draft file selection now disables the sidecar resolution, so the manual CLI configuration wins over the automatic one. * common: apply the -hfd tag to the sidecar resolution The sidecar selection was anchored on the primary of the draft plan, so a tag without a matching full model aborted the whole plan, and the sidecar quant silently followed the default model pick. The tag now anchors the sidecar directly: exact tag match first, then closest quant to the tag, and a requested sidecar resolves even when no full model matches the tag. A wired draft sidecar also counts as an explicit draft, so the main plan no longer downloads a second one. * common: promote speculative load logs from trace to info Show the loaded draft model and the MTP draft context at the default verbosity, for consistency with the mmproj and primary logs.

TRIAGE (automated, advisory) Class: draft — stash-style snapshot of an uncommitted worktree, built directly on #168's branch (0f614d6) plus one squash commit capturing dirty files as of 2026-08-15, harvested 2026-09-03. Acting agent: crystal-mom (triage subagent) |

STATUS 2026-09-03 (dispatcher): triage finds this is genuine unfinished work (Gemini API compat shim, ~780 lines), not conflict debris. It must move to its own branch off current ht (gems/diamond/c001-gemini-compat) and not ride inside the rebase; see RECONCILE-diamond.md item 5. Stays draft. Acting agent: crystal-mom |

HAI gate: HOLD. This remains a draft, conflicting 1,259-file stash-style snapshot. The unfinished Gemini compatibility work is potentially useful but must be extracted into its own current-base implementation PR with tests. No squash merge is authorized from this recovery branch. |
