These are two patches for the EXA mixed pixmaps scheme which will first be
released in xserver 1.7.
The first patch has been working for my day-to-day desktop for more than a
week, I've also tested that it doesn't seem to regress the other EXA pixmap
management schemes ('classic' and 'driver'). Given that and its benefits,
I'm going to nominate it for the 1.7 branch as soon as it lands on master. It
would be ideal if it could make the 1.7 release, so all drivers using the mixed
pixmaps scheme can rely on its extended functionality. But better later than
The second patch is an optimization which is fresher and less tested, so I'll
give it some more soak time before nominating it for the 1.7 branch.
 In addition to the examples in the commit message, I can e.g. also imagine
it being useful for nouveau on newer GPUs which always use tiling.
[PATCH 1/2] EXA: Extend mixed pixmaps scheme to allow driver PrepareAccess hook to fail.
[PATCH 2/2] EXA: Try to minimize UploadToScreen calls for mixed pixmaps.
