Last Minute AMD GFX12 Changes For RadeonSI Driver Enable ACO For RDNA4
Ahead of AMD's approaching RDNA4 next-generation graphics card launch, today a set of last minute improvements to the AMD GFX12 graphics IP were merged to Mesa 25.0 for the open-source Linux graphics driver support.
Qiang Yu at AMD submitted various GFX12 updates to Mesa 25.0-devel, the graphics IP version for RDNA4. ACO is the compiler back-end developed by Valve originally for the RADV Vulkan driver but with time adapted to the RadeonSI Gallium3D driver as an alternative to the AMDGPU LLVM shader compiler back-end. At least from my external observations it's looking like the open-source Linux driver support should be in fairly good shape for launch-day support with the upcoming RDNA4 Radeon graphics cards.
