It looks like AMD's enablement journey for RDNA 4 GPUs at Linux is finally ending, as the firm submits the final batch of patches targeting bug fixes.
AMD's "IP Blocks" Approach With RDNA 4 GPUs Has Brought In Optimal Support For The Architecture At Linux
Well, Team Red's consistency with RDNA 4 GPUs at Linux was indeed something to appreciate, considering that AMD did get on early with ensuring that the next-gen "RX 8000" series GPUs are fully compatible with Linux out of the box, and it looks like the firm has been able to achieve this.
With AMD adopting the "IP blocks" approach, not only were patches surrounding RDNA 4 consistent, but we did get to see new bits of information surrounding the release, including the presence of VCN5 encoding capability, improvements within the RT engines, and much more.
Following are some of the main changes in the latest pull request for Linux 6.11:
- drm/amdgpu: remove exp hw support check for gfx12
- drm/amdgpu: update gfxhub client id for gfx12
- drm/amdgpu: add gfx12 register support in ipdump
- drm/amdgpu: add print support for gfx12 ipdump
- drm/amdgpu: add cp queue registers for gfx12 ipdump
- drm/amdgpu: add gfx queue support for gfx12 ipdump
Phoronix reports that AMD has submitted the final RDNA 4 patches ahead of the debut of Linux 6.11, with the pull request consisting of bug fixes surrounding the GFX12 IP blocks. The source says that Linux 6.11 would consist of enough enablement to allow RDNA 4 GPUs to run out of the box on the platform. Apart from that, the patch also brought in some fixes for the "GFX11.5" or RDNA 3.5 GPU architecture, intended for the new Ryzen AI 300 processors, which are set to debut soon in the markets.
Well, this probably marks the end of RDNA 4 enablement at Linux unless AMD decides to post something at the last minute, which they often do. However, it's yet again great to see Team Red changing their approach with Linux enablement, given that past experiences at the platform weren't as optimal, and this will result in Linux consumers
