From b09a75407886fba476bb79d65b408ffc08876a75 Mon Sep 17 00:00:00 2001 From: Paul Berry Date: Tue, 21 May 2013 11:58:38 -0700 Subject: [PATCH] i965/gen7: Enable support for fast color clears. This patch adds code to place mcs_state into INTEL_MCS_STATE_RESOLVED for miptrees that are capable of supporting fast color clears. This will have no effect on buffers that don't undergo a fast color clear; however, for buffers that do undergo a fast color clear, an MCS miptree will be allocated (at the time of the first fast clear), and will be used thereafter.
