• Linux 7.0 Lands More AMDGPU Fixes For Old Radeon Hardware 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.
Article Summaries:
- Linux 7.0 has incorporated a new batch of Direct Rendering Manager (DRM) patches that mainly improve AMDGPU support for legacy Radeon GPUs. The updates, led by Valve’s Timur Kristóf, address issues on GCN 1.0/1.1 chips, fix a “black screen” problem with analog connectors on cards such as the HD 7790, and enhance consistency across display types. Alex Deucher added a fix for Apple MacBook Pros with switchable graphics, resolving cursor flicker and Wayland errors on Radeon Pro 560. Additional changes touch the Hainan GPU, new AMD IP blocks, Fastboot, and some Intel driver tweaks, many of which will be back‑ported to stable kernels soon.
