--- Comment #12 from Christian König deathsimple@vodafone.de --- (In reply to comment #8)
Also I noticed that despite I did "echo high > /sys/devices/pci0000:00/0000:00:1c.6/0000:03:00.0/ power_dpm_force_performance_level" I still get lots of power states switching in dmesg.
As Vadim correctly noted forcing any power state doesn't work here, because we need to switch to the UVD power state anyway.
BTW: Is this a regression?
