Created attachment 60410 --> https://bugs.freedesktop.org/attachment.cgi?id=60410 drm output from kernel.log
Hi, Archlinux running on a compal CL56 (radeon mobility 9700). kernel is 3.2.11 and I can't find any file for power management : - /sys/class/drm/card0/device/power_method doesn't exist and can't be created - /sys/class/drm/card0/device/power_profile doesn't exist and can't be created
Please find attached drm output from kernel.log. Apart from that it's working fine but the lack of power management reduce the run from a battery from 4h to 1h30.
