             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?
