[Mesa-dev] [PATCH 2/2] i965: Use new vtable entries for surface state updating functions.

Kenneth Graunke kenneth at whitecape.org
Tue Nov 8 10:39:45 PST 2011


Now that we have vtable entries in place, we should use them.  This
allows us to drop the cut and pasted Gen7 brw_tracked_state atoms as
they now do exactly the same thing as their brw_wm_surface_state
counterparts.
