xf86-videdo-intel branch intel-batchbuffer

[Johannes Engel]

Hi!

I just tested the intel-batchbuffer branch with my 945GM to get rid of
those performance problems using EXA and a composite manager.
As a result I can confirm, that I do not see any performance issue using
this branch. Instead I nearly see nothing.  ;)  In the attachment you can
find a screenshot of my desktop using compiz.
Without using compiz or kwin4 everything seems to be ok. Even a pure
composite manager as xcompmgr works as expected.

Disabling FramebufferCompression, Tiling and enabling ExaNoComposite did
not help.

Any suggestions?

Greetings, Johannes
