[Intel-gfx] Running DRI3 on intel-gfx

[Sedat Dilek]

Hi,

I took [1] as a base to test DRI3 on Ubuntu/precise AMD64.
Unfortunately, the packages from this repo have no DRI3 support.

So, I packaged some missing stuff, built mesa-10.1.4 and intel-ddx
from Git manually.
In the end I got somehow running a DRI3 system here.

 $ grep -A2 intel_drv /var/log/Xorg.0.log
[  1238.417] (II) Loading
/usr/lib/x86_64-linux-gnu/xorg/extra-modules/intel_drv.so

[  1238.417]    compiled for 1.15.1, module version = 2.99.911

$ egrep -i 'dri2|dri3|present' /var/log/Xorg.0.log

DRI2 or DRI3 running here?

Thanks to Maarten and Chris for some help and hints.
