Merged on Friday as part of this week's DRM kernel graphics driver fixes for the week is addressing a regression affecting many different users with the [1]Linux 6.19 development kernel.

Hitting Linux 6.19 yesterday was [2]a revert to a change introduced during the Linux 6.19 merge window to pause the workload setting in the display manager when doing idle optimization. That turned to have some unexpected fallout for AMD Radeon Linux users.

That revert commit notes it fixes a variety of bug reports such as:

- [3]HDMI Audio - missing start of streams / speakers produce "click" when idle

- [4]7900 XTX falls from bus with newer kernels

- [5]Performance regression on 7900XTX

- [6]GPU Clocks causing HDMI audio dropouts

- [7]Stuttering Video when running other GUI-program in parallel RX7600

That is for the upstream reported bug reports.

At least this problematic commit was spotted and reverted in time for the upcoming Linux 6.19 stable release in February.

Besides that revert, there are also other AMDGPU driver fixes as well as Intel Xe driver fixes and other last minute work in [8]this week's DRM fixes pull request . The changes are in place for tomorrow's Linux 6.19-rc7 kernel release.
