RV350, compositing and horrible performance.

[timothyja]

First try a newer kernel and version of mesa. There have been a lot of performance improvements in 9.1 for example.

I have already tried a new kernal/build of Mesa as I wanted to see if Vadim's shader optimizations would help my issue but they didnt seem to help at all.

Also try adjusting the CPU governor as per other comments in this thread.

I will try this out later today.

For the ttm defragmentor, see drivers/gpu/drm/ttm/ in the kernel source.

Thanks.
