[Where problems could occur] New hardware feature support. Expect further stable fixes. [Other Info] These changes have been backported to linux-6.11.y stable but across several stable revisions. Backport them as an integral so that panel display wont break between v6.11.3 and v6.11.10. Nominate for Oracular/OEM-6.11/Plucky. ========== original bug report ========== AMD Panel Replay was disabled by define in commit ab72d5945d81 ("drm/amd/display: Disable panel replay by default for now") since v6.9-rc7, and is then re-enabled on selected hardware generations in commit be64336307a6 ("drm/amd/display: Re-enable panel replay feature") in v6.12-rc1. The following 3 commits are needed to fix some reported issues for Panel Replay. commit 17e68f89132b ("drm/amd/display: Run idle optimizations at end of vblank handler") commit b8d9d5fef4915 ("drm/amd/display: Change some variable name of psr") commit bd8a957661743 ("drm/amd/display: Fix Panel Replay not update screen correctly") They are applied to 6.11.10, and help to fix regressions introduced by commit 70cc361f98a7 ("drm/amd/display: Re-enable panel replay feature") which came in 6.11.3.
