<pre>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.</pre>
