Back at the start of the Linux 6.19 kernel cycle I ran benchmarks showing some scheduler performance regressions with the new kernel. Fortunately, two weeks out from the Linux 6.19 stable release, merged this weekend was disabling the scheduler's NEXT_BUDDY feature due to performance regressions.

With the HDMI Forum blocking HDMI 2.1 open-source support, these HDMI gaming features for the AMDGPU driver were developed via trial-and-error and the limited public knowledge available.
