## AI overview

Mesa 26.3 has merged the Mesa-side support needed for RADV and RadeonSI to use DRM format modifiers on older AMD GFX6 through GFX8 GPUs. The Linux 7.3 kernel cycle adds the corresponding AMDGPU support, enabling improved buffer-layout handling for tiling, compression, performance, and interoperability.

## Source excerpt

Coming with Linux 7.3 is DRM format modifiers for GFX6 through GFX8 era GPUs covering the original Raddeon HD 7000 (GCN 1.0) graphics cards up through the Polaris and Fiji series. This work by Valve's Timur Kristóf is necessary for these older GPUs to support Vulkan-based Wayland compositors, better interoperability between OpenGL and Vulkan or other APis, compositors running on the Zink OpenGL-on-Vulkan driver implementation, and other benefits. Now merged for Mesa 26.3 is the RadeonSI and RADV user-space side support for making use of the format modifiers on these older GPUs...
