In addition to AMDGPU finally seeing HDMI 2.1 FRL support in Linux 7.2, another change worth noting in this week’s AMDGPU pull request is the continued work on enhancing the AMDGPU/AMDKFD kernel driver support for non-4K page size kernel builds. In particular this helps out with AMD graphics and ROCm for the likes of ARM and POWER.
In recent months IBM engineer Donet Tom has been working on improving support for non-4K page size systems with the AMD kernel graphics/compute driver code. Among that work is addressing fallout when running ROCm-related tests on IBM Power hardware using a 64KB page size kernel.
That patch series in full can be found on the kernel mailing list. In this week’s AMDGPU pull request for Linux 7.2, one of the patches from that series got picked up. That change is a GART fix for non-4K pages.
While this IBM engineer is focused on improving AMDGPU/ROCm support for AMD hardware on Power servers, this benefits other non-4K kernels like ARM. ARM Linux servers show very nice benefits from a 64K page size kernel.
The full list of AMDGPU patches for the week sent in for Linux 7.2 can be found via this pull request.
