Testing R9 285 Tonga on drm-next-4.11-wip
This commit has the effect that doing
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
instantly forces fan to (I guess) max, where normally it doesn't
need anything like as fast with the clocks high when doing nothing else.
Ping - just in case this got missed, still the same on current
drm-next-4.11-wip
Just a heads up, Rex was looking at this, but it's Chinese New Year this week.
OK, thanks & Happy new year.
