Actually I can't use my HD 7950 with KDE becuase of
so I attached my display the Intel HD 4000.
I still do bitcoin mining (OpenCL) on the 7950 and I notice it doesn't switch to higher power states anymore (everything works flawlessly if I attach the display to the 7950). Forcing the card to the lowest power state if no display is attached is a bad behavious because of GPGPU computing.
I'm using Linux 3.12-pre (drm-next).
Please attach your dmesg output when the radeon card is doing bitmining.

dmesg while bitmining
Here it is.
What does the dpm debugfs output show when you are bitmining? e.g.,
Also does manually forcing the performance level to high help? E.g.,
echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level
Note, you may need to adjust the paths above depending on your system.

Does this patch help?
When mining I get lowest power level (power level 0).
Of course if I echo "high" into power_dpm_force_performance_level I get power level 2 (the highest).
I will try attached patch tomorrow, thanks.
The fix worked, thanks.
I hope you can help me with my KDE issue too: it's a pity having to use the Intel HD 4000 which doesn't even support my monitor's resolution (2560x1600).
Has this been pushed upstream?
Will this also fix the muxless render provider scenario too?
Or maybe I should ask does this big affect more than just SI?
It's in my 3.13-next branch:
Was this fixed?
