VANGOGH clocks get stuck after profile_standard or profile_peak usage
Normal boost clocks are 1600 MHz, profile_peak and profile_standard lower those to 1300/1100. However, when moving back to auto/high the clocks are still stuck at the lower level.
Current workaround seems to be
echo manual | sudo tee /sys/class/drm/card0/device/power_dpm_force_performance_level
echo "c" | sudo tee /sys/class/drm/card0/device/pp_od_clk_voltage
This gets it back to normal, and switching to auto/high after the workaround keeps the high clocks.
