Hmm this patch seems to have been forgotten. Even if with modern CPUs on x86 hw it doesn't provide an improvement, if it helps macppc with nvidia, I think it should be aded to our tree. It's possible to only enable EXA on macppc for instance (or let the users enable it via xorg.conf). Thoughts? (Note that we're getting out of time for 5.9, so it may not make it into the release) -- Matthieu Herrb
