Memory/CPU clock locked at minimum (SI/Southern Islands/Oland)
Brief summary of the problem:
Most of the time on boot or resume my memory/shader clocks are locked at the minimum possible setting (300mhz), unless I've rebooted from Windows. After resetting the GPU via /sys/kernel/debug/dri/0/amdgpu_gpu_recover, this sometimes fixes itself (~50% of the time).
If I use power_dpm_force_performance_level (set to high), it will stick on the maximum clocks. Interestingly, setting it to auto after I've set it to high doesn't take it back to the minimum, just leaves it at the maximum. i.e. it seems it's not making any power decisions at all.
EDIT: except if I engage UVD, in which case it scales up to 800mhz memory clocks (1.15ghz max) and 730mhz shader (750mhz) and stays there while the video is running, downclocking once it stops.

I also have an [SI/Southern Islands/Oland] card [AMD Radeon HD 8600 / 8700M] and found that the
autooption for thepower_dpm_force_performance_leveldoes nothing.The settings 'low' and 'high' works as expected (monitoring the GPU clocks using 'nvtop' and observing the graphics performance accordingly). But setting 'auto' after 'high' keeps clock high; Setting 'auto' after 'low' keeps the clocks low, even trowing high demand graphics to the GPU. After boot, 'auto' is the default, and the clock are static in the lowest clock.
Is there any workaround to make the automatic power management work for this card?
Thanks.
