--- Comment #13 from Bruce Cherniak <bruce.cherniak at intel.com> ---
Your most recent response indicates that you are running with dri drivers. 
This is not something I was aware of.  And, I just tried the demo app, and sure
enough, it fails with dri driver -- either llvmpipe or OpenSWR.  We're finally
on the same page. :)

However, most of our customers require only the standalone GLX drivers,
eliminating the need to install dri or disturb other configurations; only the
few libraries that build in .../lib/gallium (libGL.so, libswrAVX.so,
libswrAVX2.so) are required and LD_LIBRARY_PATH is the only environment change
necessary.

We regularly build mesa with OpenSWR on CentOS 6 and 7, so I see no reason to
stick with mesa 13.  And, several of our customers build and supply specific
release libraries with their binary release, so there is no additional install.

Using the classic software rasterizer would be a very last resort and unless
there is a specific reason to install/run dri, there is no hard/fast kernel
requirement and no specific version of (older) mesa that must be run on CentOS
6.  The developer toolchain needs to be updated, but this is quite doable.

We can follow up with a phone call, if that would be more convenient, to
understand your specific requirements.

In the meantime, I'll try to look into the dri failure on both llvmpipe and
OpenSWR.  But this doesn't appear to be an OpenSWR specific issue.

Thanks,
Bruce
