well, freedreno and vmware ddx still use XA.. they both could probably
be ported to use glamor instead, but that hasn't been done yet..
At least for freedreno with upstream drm/kms driver, one can just use
-modesetting ddx instead. But that doesn't work w/ android fbdev
driver. I need to check again w/ a more recent -modesetting+glamor,
but when I tried it a few months ago, there were some cases of
rendering corruption (but I didn't have time to debug and see whether
that was a freedreno issue or a glamor issue).
I wouldn't recommend new users of XA at this point, but I don't think
we are quite at the point where we can remove it.
