Why The Radeon Gallium3D Performance Is Down
winsys/radeon: move GEM domains out of the drivers into winsys
This other commit to the Gallium3D winsys for the Radeon driver and also touches the R300 and R600 Gallium3D drivers directly magically fixes a few FBO regressions, which Marek Olšák says in the commit message he can't even explain why those regressions get fixed on R600g (note: not R300g). But this seems to cause a performance issue on at least R300 in certain cases.
After the Phoronix Test Suite reported these two commits, I have also manually verified they affected the performance in the particular configuration under test.
