From 7f854a5028ef00a0e041e78a770456204dc58eef Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 16 Dec 2011 13:18:55 -0800 Subject: [PATCH] intel: Fix performance regression in Lightsmark since HiZ changes. Since the refactor in d7b33309fe160212f2eb73f471f3aedcb5d0b5c1, depth in the miptree changed from 1 to 6, so we always decided it didn't match, and we would relayout to something that would still not "match".
