The patch series includes AMDGPU Display Code (DC) refactoring for modularity, HDMI pipeline cleanup, and additional KUnit test coverage to catch regressions. No new end-user HDMI features are included in this round. The patches are expected to land in the Linux v7.3 cycle later in the year. ## Full article daily.dev links to this article rather than hosting it.
