AMDGPU Linux Driver Patches Posted For Enabling GFX13 Graphics IP - RDNA5

Since the beginning of the year there have been AMDGPU LLVM back-end patches for GFX13 as AMD's next-generation graphics IP. This is most likely for RDNA 5 graphics. Now out today are the GFX13 patches finally surfacing for the AMDGPU Linux kernel graphics driver. AMDGPU maintainer Alex Deucher posted the patch series today for enabling the GFX 13 / GC 13.x support for this open-source kernel driver. The set of eight patches is more than 12.6k lines of code, not counting the typical massive header files. This also includes support for specific GFX 13.0.1 and GFX 13.0.4 targets. Digging through the patches now but so far nothing jumping out as being too revealing about expected RDNA 5 capabilities or new features. Those interested can find the AMDGPU kernel driver GFX13 enablement patches on the mailing list. We'll see what follow-up patches come following this initial enablement for wiring up any new features. Given the timing of these patches now, presumably the GFX13 support will be introduced in the Linux 7.5 kernel. Within the kernel already is Display Core Next 6 (DCN6) and other IP blocks that will likely also be making up the RDNA 5 GPUs.
