Description

This ships the gamescope shim built from gamenative-drm master now that GameNative/gamenative-drm#44 is merged, as payload 20261102.4. App master runs payload 20261102.3, whose shim was built from #44's branch head (5831f1e) before the merge.

drm master (2bfe8b3) has one change beyond #44:

• icd_shim: the X11 wrapper's feature lift, served by the shim GameNative/gamenative-drm#45 (d3c4bdf, Joshua Tam), "icd_shim: the X11 wrapper's feature lift, served by the shim". It touches only the shim and docs (icd_shim/src/advertise.rs (new), lib.rs, placed.rs, proxy.rs, docs/04-gamenative-app.md).
  • The shim now reports the same ten core VkPhysicalDeviceFeatures bits that the X11 path's libvulkan_wrapper.so lifts.
  • At vkCreateDevice it masks them back to what the driver actually answers. textureCompressionBC is not lifted.
  • On a driver that reports its own capabilities this is a no-op.
  • It needs no gamescope, Xwayland or daemon change.

What changes in this PR

• GamescopePayload.VERSION = 20261102.4.
• jniLibs/arm64-v8a/libgamenative_drm.so does not change. Built from drm master, the daemon is 9d3619681d9d5e382f78f2953c98ba1eff645334df8b7af8e88bc166ea774828, byte-identical to the one already on master (5144ef9c… in the APK after stripping), because the daemon sources are unchanged since #44's head.

Build (NDK 27.3, rustc 1.98.1, daemon and shim in one cargo invocation, SOURCE_DATE_EPOCH = head commit time)

• Test gate passes in rust:1-bookworm: gndrm-daemon 99 unit + 36 golden + 8 diag, gndrm-android, gndrm-uapi 19 + 2 ABI.
• Shim: cargo test -p adrenotools_gamescope --lib, 75 passed.
• cargo clippy --target aarch64-linux-android -p adrenotools_gamescope -p gndrm-android -p gndrm-daemon --all-targets -- -D warnings is clean.
• tools/check-exports.sh passes.

It is uploaded and verified on both CDN hosts, including the members from the served copy. It is 20261101.6 with only the shim replaced; every other member is byte-identical. 20261102.3 stays on the CDN.

Device

The re-anchoring runs (Retroid Pocket 6, Odin 3) will be added to this PR when they are done.

Test steps

1. Install the APK and open a game with the display server set to gamescope. On first launch payload 20261102.4 downloads. In logcat, expect Gamescope payload 20261102.4 ready, and gn-vkshim: ICD loaded [shim 202611021006 2bfe8b3] in the game process.
2. Set the FPS limit to 60 on a 60 Hz panel.
   • Every 10 s: gn-vkshim: present mode: declared=fifo … cap=60 … feedback=on … discarded=0 fallback=0.
   • gndrm-daemon: vsync: check … late=0.
3. A DXVK game at a D3D11 feature level that needs the lifted bits (for example multiViewport) creates its device. On a driver that already reports them, nothing changes, and no mask line is printed.
4. Regression check: Dave the Diver with in-game VSync on still holds about 60 at cap 60.

Summary by cubic

Bumps the gamescope payload to 20261102.4, replacing the shim built from the gamenative-drm #44 branch head with one built from master once #44 merged. The shim now reports the same ten core Vulkan physical device features that the X11 wrapper lifts, masking them back to the driver's real answers at vkCreateDevice; drivers that report their own capabilities see no change. The daemon is byte-identical to the one already on master, so only the shim member changes in the payload.

^{Written for commit 2c3945e. Summary will update on new commits.}

Summary by CodeRabbit

• Updates
  • Updated the Gamescope payload version. The app now recognizes installations as ready when their version stamp matches the current payload; installations with an older stamp are not considered current.

Full details: Title check

Explanation

The title "gamescope: payload 20261102.4, shim from gamenative-drm master" names the main change: the gamescope payload is bumped to 20261102.4 and its shim is rebuilt from gamenative-drm master. The PR's changed file (GamescopePayload.VERSION) and the objectives match this. The title is specific, though somewhat long at 62 characters and 7 words, and it does not mention the Vulkan feature-lift behavior.

Full details: Description check

Explanation

The description follows the repository template in substance. It has a clear '## Description' section explaining the shim rebuild, the daemon byte-identity, build and test evidence, payload hashes, and test steps. The 'Type of Change' and 'Checklist' sections are filled in. The '## Recording' section is left as the template placeholder, and the checklist item for attaching a recording is unchecked. The author states device re-anchoring runs will be added later. The description is mostly complete, so the check passes, but the missing recording should be noted.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 1 files.
