This is my old set which enable using Pixman on Mesa for some texture conversion fast paths. As is this passes Piglit quick set on my IVB.
For general case this does not offer essentially better fps or such but these were recently tested on Chromebook with HSW inside where it showed promising drop on Watt drain. With/without Pixman Mesa was compiled with march=corei7 Number here indicate % change in Watts, for comparison was used averages of multiple runs. While Watt drain reduced performance remained +/- on the same level.
