From 5ae983c85b8af7553223c1d3b07199ebb181d0d3 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 17 Aug 2017 00:44:41 -0700 Subject: [PATCH] i965: Use ISL for emitting null surface states. We handle the Sandybridge multisampled 2D surface hack here, rather than in ISL, because it requires allocating a BO, and is kind of messy.
