Hi Michel,

Thanks a lot for your investigation.

Yes, a lot. My benchmark went up from ~12fps to ~19fps and the
"fallback" is gone according to the profile.
I am still only at 50% of intel-2.1.1/xorg-server-1.3's throughput,
however a lot of time is spent inside the intel-driver - I guess its
related to the refactoring to make it GEM ready.

Thanks again, Clemens
