Description Aleksey Fedotov 2013-05-24 10:27:50 UTC
Created attachment 79751 [details]
dmesg from machine with two cards.

I have a laptop with two ati cards:
Mobility Radeon HD 6620G 
Radeon HD 6400M

Enabled powersave mode on both cards:

#echo dynpm > /sys/class/drm/card0/device/power_method
#echo dynpm > /sys/class/drm/card1/device/power_method

Clock speed on the first card reduced almost immediatly:

#cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 200000 kHz
current engine clock: 7990 kHz
default memory clock: 667000 kHz

But second card don't react at all:

#cat  /sys/kernel/debug/dri/1/radeon_pm_info
default engine clock: 800000 kHz
current engine clock: 799940 kHz
default memory clock: 800000 kHz
current memory clock: 799870 kHz
voltage: 900 mV
