https://bugzilla.kernel.org/show_bug.cgi?id=205393 Bug ID: 205393 Summary: [amdgpu powerplay] vega10: custom pp_table, AVFS accidentally reenabled after display powersave Product: Drivers Version: 2.5 Kernel Version: 5.4-rc5 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: haro41@xxxxxx Regression: No Created attachment 285755 --> https://bugzilla.kernel.org/attachment.cgi?id=285755&action=edit patch to prevent AVFS reenabling (against 5.4-rc5) When uploading a customized powerplay table, AVFS feature becomes correctly disabled. But after a power save (blanc screen) event, AVFS becomes accidentally enabled again. This results in unwanted gfx voltage changes. Example: vddc = 1.075V after pp table upload (correct). vddc = 1.150V after power save event (set by smc because AVFS feature reenabled). I have debugged this issue and found a simple solution. There is a patch attached, that solves the problem. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
