BugLink: https://bugs.launchpad.net/amd/+bug/1964850 [Impact] Disjoint trackpad/mouse path found on PSR capable panels. [Fix] Two fixes from v5.17-rc6 that only turns off vblank IRQs when PSR is not enabled, originally for commit f94cf1cb1796 ("drm/amdgpu/display: set vblank_disable_immediate for DC") that was being backported to LTS stable 5.15.y, and therefore oem-5.14. [Test Case] Simply move the mouse around. [Where problems could occur] This follows for AMD platforms, the power-saving performance may not be as good as before, but while we don't have such energy-saving certificate program for AMD yet, this would become something to be fully addressed in the future. [Other Info] These fixes have been applied to v5.15.27, and oem-5.14 currently has v5.15.25 in -1028, therefore only oem-5.14 is nominated, but probably they will still be included through stable patch backport in the next release.
