Hi, 

Rafael if you pluged only dvi, dpm changes power levels? 

Alex, i'm not sure if i should commit new bug(i have HD7770 GHz Ed. from
Asus+olny one dvi display). In my case i've got power_level = 0 (low) all the
ime. It reclocks olny when i try with UVD but it kills my machine. Forces power
levels works olny for "low" level in other case "auto"(default) or "high":
"bash: echo: write error: Invalid argument". It doesn't matter if power state
is set to 'performance' or 'balanced'.

Static PM works ok(UVD too)(with something similar to Michael's tip of course).

kernel: drm-next-3.11 or linux-next-20130712
