--- Comment #131 from Marek Olšák <maraeo at gmail.com> ---
DPM seems to be working here. If I do "sudo cat
/sys/kernel/debug/dri/64/radeon_pm_info" with no 3D app running, I get:

power level avg    sclk: 30047 mclk: 15000

If I do the same while glxgears is running, I get:

power level avg    sclk: 80000 mclk: 112500

That said, the performance seems to be lower than Bonaire. The open source game
Torcs has 27 FPS with Bonaire and 18 FPS with Hawaii. radeontop shows 100% GPU
usage with Hawaii while Torcs is running.
