[Mesa-dev] [PATCH v2 0/8] i965 gen6: Pass-through GS program for future use by transform feedback

[Paul Berry]

Ok, I've cleaned up and made changes according to the suggestions made
on the mailing list.  I believe all that needs review now is patch 5/8
(Allocate URB space for GS).  On Eric's suggestion, I changed this
patch to only allocate URB space for the GS when the GS is actually in
use.  The PRM indicates the need for some kind of flushing when URB
entries are reallocated from the GS to the VS, but it's not clear
exactly how to do the flush, so for now we just do a full pipeline
flush in this situation.

I'm hoping that I can get review on that this afternoon while I'm
re-checking my piglit results, and push the patches this evening.
