It seems we're solidly off to the races now in getting the AMD RDNA4 graphics brought up on the open-source Linux graphics driver stack. Since writing about a lot of GFX12 code beginning to land , that flow of RDNA4/GFX12 patches to Mesa Git has only increased.
Some of the recent work landing in Mesa 24.2-devel for the next generation AMD Radeon graphics include a third round of GFX12 enablement for RADV , register emission fixes for GFX12 , GFX12 DCC support for the RadeonSI driver for that delta color compression performance optimization, updating the AMD ADDRLIB , more GFX12 changes within Valve's ACO compiler code, and other changes.
The AMD Linux kernel graphics driver components are also busy preparing for RDNA4 . Here's to hoping that the RADV and RadeonSI drivers will have a nice initial RDNA4 driver support experience by the time Mesa 24.2 ships in August.
