Following last week's main set of DRM kernel graphics driver feature updates for Linux 7.0, merged on Friday to Linux 7.0 Git was the first round of fixes to these Direct Rendering Manager drivers. Dominating most of the code changes in this latest pull were AMDGPU fixes, including more enhancements for aging Radeon graphics processors.
The now-merged code to Linux 7.0 includes more AMDGPU fixes from Timur Kristóf of Valve's open-source Linux graphics team. Timur Kristóf has been the one leading the effort to improve the old AMD GCN 1.0 and GCN 1.1 GPU support with the AMDGPU kernel driver and drove through that default change from the legacy Radeon DRM driver. Timur has continued taking care of some loose ends like some APU support issues. The latest patches now part of Linux 7.0 take care of a "black screen" issue observed with analog connector support when using the AMDGPU DC display code with the likes of the Radeon HD 7790. The code also makes the analog connector support more consistent and closer to parity with other display connector types in the AMDGPU display code.
