            Bug ID: 72602
          Assignee: dri-devel at lists.freedesktop.org
           Summary: [REGRESSION] r600 cayman: forced performance level
                    gets reset to auto when playing a video with vdpau
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: h.judt at gmx.at
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

Steps to reproduce:
1) echo low > /sys/class/drm/card0/device/power_dpm_force_performance_level
2) cat /sys/class/drm/card0/device/power_dpm_force_performance_level
   low
3) start playing a video (vdpau)
4) cat /sys/class/drm/card0/device/power_dpm_force_performance_level
   auto

Interestingly, I can repeat step 1 now and the video will play correctly, with
the value staying at "low". So it seems this occurs only when initializing
video playback (vdpau).

This started happening with kernel 3.12.0 or a rc. It did not get reset with
<=3.11.8.
