So to move to systemd, I rebooted, and am now running awfully hot and loud. The CPU is scaling fine, but not video.
cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 392000 kHz
current engine clock: 391500 kHz
default memory clock: 350000 kHz
current memory clock: 342000 kHz
It never changes, like it is stuck at default clocks, which I assume it is.
cat /sys/class/drm/card0/device/power_method
dynpm
That at least reads correctly, but I suspect it's not working.
echo profile > /sys/class/drm/card0/device/power_method
echo auto > /sys/class/drm/card0/device/power_profile
The above has no effect at all, either.
Finally, in Xorg.0.log:
[ 1132.325] (WW) RADEON(0): Option "DynamicPM" is not used
[ 1132.325] (WW) RADEON(0): Option "ClockGating" is not used
[ 1132.325] (WW) RADEON(0): Option "DynamicClocks" is not used
Up until my last reboot, all was well. Now it's not. But, everything looks fine, as far as my reading of any documentation does. My kernel has not changed, but Xorg may well have updated, and apparently broke.
Setting a low profile seems to, work, however:
echo profile > /sys/class/drm/card0/device/power_method
echo low > /sys/class/drm/card0/device/power_profile
cat /debug/dri/0/radeon_pm_info
default engine clock: 392000 kHz
current engine clock: 128250 kHz
default memory clock: 350000 kHz
current memory clock: 135000 kHz
PCIE lanes: 1
Any ideas? The low profile can't even play videos well.
