Phoronix: R600g Now Works With Xorg State Tracker

While the ATI/AMD R300 Gallium3D driver has long worked with the Xorg state tracker, for providing EXA and X-Video acceleration atop this next-generation Mesa driver architecture, the R600 Gallium3D driver that supports all modern Radeon GPUs now works with the Xorg state tracker too...

Has anyone tested the xorg state tracker recently?

I keep hearing it's the future (which is probably true), but I couldn't find a reason to switch from xf86-video-ati yet. Is it stable and feature complete enough for end-users yet?

How do you use that anyway? Is it an xorg.conf tweak?

By analogy with r300g?

Someone should run that HWACCEL test in Firefox with this, along with some other xrender tests.

http://www.x.org/wiki/GalliumStatus - xorg state tracker is market as "DEPRECATED" - is it true?

I was wrong in previous comment.
Driver "r600g" in xorg.conf

I tried with 4850.

Sort of works here (RS780). No corruption but 2D accel seems to be disabled by default, have to add Option "2DAccel" "on" to xorg.conf. With 2D accel enabled there's some corruption and a lot of spam in xorg.log

R600G(0): xorg_composite_accelerated fallback Component alpha not supported with source alpha and source value blending. (op=3)

It's also slower than regular ddx and doesn't seem to have all the xrandr options the regular ddx has. (e.g. missing option to set underscan)

but 2D accel seems to be disabled by default,

The same thing here, but I don't find it any slower than before. However, I'm a bit disappointed because of this:

[ 2951.342] (WW) R600G(0): Option "ColorTiling" is not used
[ 2951.342] (WW) R600G(0): Option "RenderAccel" is not used

[ 2951.342] (WW) R600G(0): Option "SwapbuffersWait" is not used

Does this means I now don't have Page Flipping?
