Mesa 26.3 has merged user-space support for DRM format modifiers, targeting AMD GFX6 through GFX8 era GPUs. This work, primarily led by Valve's Timur Kristóf, extends to graphics cards from the original Radeon HD 7000 series up to Polaris and Fiji GPUs. The RadeonSI and RADV drivers in Mesa now incorporate this functionality. The integration of DRM format modifiers, which are planned for Linux 7.3, is crucial for enabling these older GPUs to support Vulkan-based Wayland compositors. It also facilitates improved interoperability between OpenGL and Vulkan or other APIs, and allows compositors to run on the Zink OpenGL-on-Vulkan driver implementation, among other benefits.
