Comment # 46 on bug 82201 from
It doesn't seem to be completely solved for me sadly.
I'm using: http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.19-wip

It is a lot better than before but it seems like only the mem reclock (?) is
working.

Idle:

# cat /sys/kernel/debug/dri/*/radeon_pm_info
uvd    disabled
vce    disabled
power level avg    sclk: 30000 mclk: 15000

CS:GO or Unigine Heaven running:
# cat /sys/kernel/debug/dri/*/radeon_pm_info
uvd    disabled
vce    disabled
power level avg    sclk: 30000 mclk: 135000

I thought it was fixed too when I first started cs:go. But it when doing some
more testing i noticed that I got about 40fps where I had ~80fps before. So I
ran the Heaven benchmark and got about 10-15fps there (IIRC I had about 40
before).

The fans doesn't spill up either so I guess that the low core clock is to blame
there also.

If there is anything you want me to test/post, I'll gladly do so.

Kai, can you see if this is also the case for you?
