The following changes since commit 338a95a95508537e23c82d59a2d87be6fde4b6ff:
drm/radeon/sumo: implement support for disable_gfx_power_gating_in_uvd flag (2013-07-03 17:37:31 -0400)
are available in the git repository at: git://people.freedesktop.org/~agd5f/linux drm-next-3.11
[…]
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
