[Intel-gfx] [PATCH] Remove EXA support and make UXA the default.

Wed Feb 25 07:42:47 CET 2009
UXA should now have better performance characteristics than EXA for all usage
other than potentially repeated redundant reads of buffer objects. (Note that
some performance regressions with 3D are reported, but have all been attributed
to DRI2). Without further EXA interface changes it is the only way to support
DRI2. EXA development in master has now gratuitously broken drivers, and the
current developers have taken a track that the original authors (myself and
keithp) strongly disagree with. As a result, EXA is now merely baggage in
our driver.
UXA continues to be distributed within the driver until another driver decides
to use it. At that point the code will be moved into the server to be shared.
