Description almos 2011-11-13 09:22:37 UTC

On my barts gpu the dynpm is completely unusable, as there is a black frame every time the clocks are changed. I looked at the code, and it changes all parameters at once. I think it is too much for one vblank period. Maybe setting voltage/core/memory in separate vblank periods fixes this?

That would definitely help.

The new dpm method made this one obsolete. Closing.
