AMDVLK remains close to the upstream, internal state of the official AMD Vulkan driver but with continuing to use its LLVM-based compiler back-end while the Windows/Linux official Vulkan driver builds continue using the internal AMD proprietary compiler back-end. There continues to be work in the direction of switching over the LLVM back-end everywhere, but it doesn't appear to be ready yet.
With this week's code updates to the AMDVLK sources, changes include:
- Previous XGL commits have brought Steam Play / Proton fixes and that has continued this week. Mentioned this week is fixing a game crash affecting at least the game Killer Instinct.
- PAL has Wayland windowing system improvements.
- Swapchain composite alpha support via XGL/PAL changes.
- GPU profiling improvements with being able to now inject shader/pipeline hashes into the thread traces.
- Compiler improvements/optimizations with AMD's LLVM Pipeline Compiler (LLPC) for shader compilation.
- Various other fixes.
Just another week's worth of code committed this morning to the respective repositories. As AMDVLK isn't widely packaged, those wishing to try out this "official" open-source AMD Vulkan driver over RADV can find the build instructions here.
I am currently wrapping up some benchmarks on this week's release of Radeon Software 18.40 with the PRO and Open components compared to various Mesa/AMDGPU versions. The timing should work out well to get a fresh AMDVLK run in there from this morning's code while those numbers should be out already by this afternoon.
