From 838bfe0c46969c359be8f5d02e2b41bb7ff044e1 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 30 Aug 2011 16:58:03 -0700 Subject: [PATCH] i965/vs: Fix setup of scratch space pointer on pre-gen6. We were failing to relocate, so on the first draw run our scratch would tend to get written to 0x0.
