Xorg log file for xf86-video-ati, r6xx-r7xx-support branch

Hi,

after having read http://www.botchco.com/agd5f/?p=37 I wanted to test out the new R600 acceleration features on my HD3400. However, Xv does not seem to work:

$ xvinfo 
Xlib:  extension "Generic Event Extension" missing on display ":0.0".
X-Video Extension version 2.2
screen #0
 no adaptors present

As far as EXA is concerned, although EXA seems to be enabled (see log) everything (especially scrolling and moving windows) is way slower than when using the driver from the master branch.

I attach my xorg.conf and log file.

You need to install the kernel modules from the r6xx-r7xx-support branch of the drm.  You also need to add:
Option "DRI" "TRUE"
to the device section of your config.

Oh yes, that did the trick. Now EXA and Xv seem to work.
The only thing that still looks strange is the log contains thousands of lines with 'Ran out of VB space!' but seemingly without negative effects:

$ grep 'Ran out of VB space!' /var/log/Xorg.0.log | wc -l
80318

Anyway, thanks!

Just did. It's 'Copy: Ran out of VB space!' now.
Let me know if you need more info, I'm closing this bug for now as my original problem is solved.

Can you my latest commit?  I attempted to handle the out of VB case properly.

I just pulled (to bd141aa) to try your latest work. Sadly, using any version newer than commit ec60ef0 causes my system to lock up hard on X start, rebooting after a few seconds.
