Radeon EXA feedback

[Francesco Biscani]

Hello,

I'm running right now latest Xorg CVS + latest EXA driver (16 - from 
http://people.freedesktop.org/~anholt/radeon-exa-16.diff ). What to say, 
finally "xcompmgr -a" runs ok :-) It's very smooth here. I've done some 
limited testing with mplayer and glxgears: both XV and DRI/GLX seem to work 
ok on EXA. Only small glitch is a strange "shadow" surrounding cursor when 
using XV, but apart from that everything is smooth. Oh, and some slide 
transitions in OpenOffice Impress are pretty slow too. Some info:

Two questions:

1) does the RenderAccel option still makes sense on EXA?
2) when can we expect working translucent windows? :P Right now they are a 
little faster than XAA, but still far from usable.

Great work! Thanks very much, you guys rock :)
