RADV Vulkan Driver Lands Initial Support For GFX11.5 "RDNA3 Refresh"
Last week AMD upstreamed GFX11.5 support to the RadeonSI Gallium3D driver for OpenGL with Mesa 23.3. Now this week Valve's Samuel Pitoiset has made the similar changes to the RADV Vulkan driver.
With the driver code paths for GFX11.5 largely taking the same routes as those of existing RDNA3 / Navi 3 with GFX11.0, the upstreaming isn't too significant. Enabling the GFX11.5 support in the RADV driver amounts to just adding the new "CHIP_GFX1150" ID and a minor command buffer change to a function.
The couple lines of code for GFX11.5 in RADV can be found via this merged code ahead of this quarter's Mesa 23.3 release.
GFX11.5 is expected to be the refreshed RDNA3 graphics expected to appear with next-gen APUs/SoCs, likely in the Ryzen 8000 series. Wherever the GFX11.5 graphics end up appearing, at least we're seeing this new hardware enablement for the Linux kernel and Mesa continue to happen pre-launch so there will hopefully be nice out-of-the-box support come launch day.
