[Intel-gfx] i915 compositing performance improvement w/ kwin 4.3

[Adam Lantos]

Hi,

Today I upgraded my i915 system to kde-4.3, and - well, compositing
performance is GOOD, at least.

I'm using my laptop with latest drm-intel, mesa-7-5-branch head,
xf86-video-intel master, and 2d performance is really outstanding
compared to the previous releases. I've been using the 2.8ish driver
with .31-rc kernels for weeks and the system is pretty stable through
suspend to ram / disk cycles and dualhead sessions.


Keep up the good work, guys!
thanks,
 Adam
