[Mesa-dev] [PATCH] [v2] i965/bxt: Production thread counts

[Jason Ekstrand]

Assuming the URB sizes mean the sensible thing (didn't we just clean that
up?):

Reviewed-by: Jason Ekstrand <jason.ekstrand at intel.com>

I'm a little wary of the URB size since the bspec actually gives a range.
Might be better to drop it to 128 just to be safe.  I guess if we find a
problem, we can always push a patch to stable to drop it to 128.  Do what
you'd like.
