From 4de2cfc3a08819b869ac3326f171d0a9f0fecf65 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sat, 22 Oct 2011 11:07:00 -0700 Subject: [PATCH] i965/gen7: Fold WM surface state prepare()/emit() together. These produce BRW_NEW_SURFACES (used by binding table emit()) and BRW_NEW_NR_WM_SURFACES (used by WM unit emit()). Fixes a bug where with no texturing and no color buffer, we wouldn't consider the null renderbuffer in nr_surfaces. This was harmless because nr_surfaces is only used for the prefetch info in the unit state.
