just a note that I tested that branch successfully on an ASRock E350M1
(with coreboot) and Radeon HD 6310.
Setting the performance level also seems to work.
$ echo low | sudo tee
/sys/devices/pci0000:00/0000:00:01.0/power_dpm_force_performance_level
low
$ more /sys/devices/pci0000:00/0000:00:01.0/power_dpm_force*
low
I have no idea though how to check the effects, that means if actually
less power is drawn and the chip is cooler.
Thanks,
Paul
PS: Here is the output from `kern.log`.
