From 3340b47c2280346ba2f44dde44466f09d898b9d8 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 8 Feb 2012 17:14:15 -0800 Subject: [PATCH] i965: Fix border color on Ironlake. Ironlake appears to check our pointer against the General State Base Address upper bound, rather than ignoring the zero bound as it ought. Unfortunately, since we leave GSBA set to zero, there is no logical upper bound. Set it to the maximum possible value, which should work since our virtual addresses only go up to 2GB. +94 piglits. NOTE: This is a candidate for stable release branches.
