On Tuesday, AMD submitted new code to DRM-Next for its AMDGPU and AMDKFD kernel graphics and compute drivers in preparation for the Linux 5.20 cycle, which kicks off in a few weeks. As evidenced by the content contained in the query request, AMD has ongoing support for next-generation GPUs (RDNA 3 consumer GPUs and Instinct CDNA accelerator cards).
As noted a few months ago, however, recent AMD graphics code work has focused on enabling new GPU instructions based on IP blocks, rather than bringing a huge patch in one fell swoop.
The pull request of the day mentioned a number of DCN improvements, as well as MMHUB, SMU, VCN and the other IP blocks that make up the next generation of AMD GPUs.
With AMD’s incremental approach, it’s hard to tell exactly where it is already, but let’s hope that Linux 5.20 brings good enough support for the Radeon RX 7000 series “RDNA 3 GPUs”.

It is planned that the Linux 5.20 merge window will open around late July, while the stable release will not be available until around late September.
Referring to the legendary AMD release schedule, both Linux 5.20 and Mesa 22.2 are expected to provide stable upstream kernel support at the beginning of the RDNA 3 graphics card release.
Finally, in addition to the enablement of new modules, the day’s AMD DRM-Next update includes a variety of fixes — from eDP display to USB-C and other issues.
There is also initial support for devcoredump, enabling high-priority graphics queues for compatible GPUs, GPU reset improvements, ASPM power management support for more GPUs, and various other changes.
