This patch is: Reviewed-by: Eric Anholt <eric@xxxxxxxxxx. Which tests did you find improved, specifically? I'm seeing openarena improved by 1.01897% +/- 0.247857% (n=16). x11perf -aa24text and -copypixwin looked like they had about the same level of improvement. This conflicts with a change in -fixes. I think this means that it should go in -next once -fixes gets pulled in that. Peter Brown had suggested to me at one point that we could queue up multiple jobs at once by patching the last few bytes of the current job to jump to the next one. I haven't fully thought through how you'd interlock to make sure that the CL wasn't going to execute the old contents before you go to sleep, but it has the promise of being able to mask out the flush/frame done interrupts.
