Bug #: 42878 Summary: black flash every time pm changes clocks Classification: Unclassified Product: DRI Version: XOrg CVS Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: aaalmosss@gmail.com
On my barts gpu the dynpm is completely unusable, as there is a black frame every time the clocks are changed. I looked at the code, and it changes all parameters at once. I think it is too much for one vblank period. Maybe setting voltage/core/memory in separate vblank periods fixes this?

That would definitely help.
