RadeonXaaToExa
The open source -radeon / -ati driver still uses XAA by default in Intrepid. For Jaunty, evaluate changing to the new EXA.
While as a new technology EXA may not be 100% stable yet, neither is XAA without problems. And lately we're noticing a pattern where -ati users with problems in XAA see them disappear when switching to EXA. However, much of this data is anecdotal. Even so, upstream is also encouraging switching to EXA by default, and may be doing this themselves soonish.
For Jaunty, we should change to EXA by default for -ati / -radeon for community testing. Extra efforts should be put into getting EXA issues forwarded upstream. Existing XAA bugs marked "Needs EXA" should not be closed prior to Alpha-3.
At Alpha-3 we will revert back to XAA unless the following criteria are met: a) No critical bugs specific to EXA are open against xserver-xorg-video-ati b) All High-importance EXA -ati issues are either forwarded upstream or have a patch in the works on our end c) There are no more than a dozen high or medium priority EXA-specific -ati issues open
