From c3c43702991d1590c98039aab18e202d33ca07c0 Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Sun, 22 May 2016 20:27:23 +0200 Subject: [PATCH] nvc0: do not invalidate compute constbufs on Kepler Constbufs are only aliased on Fermi and this will reduce the number of flushes when we switch between 3d and compute.
