From 8fba8d4ee7632ae185f70356093e10a563ea64cd Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 13 Aug 2013 11:34:01 -0700 Subject: [PATCH] i965: Add Gen6 depth stall flushes before disabling depth in BLORP. We emit these before configuring depth in the normal path, or actually using the depth buffer in BLORP - we just failed to emit them when disabling depth altogether. On Sandybridge, this also requires the post_sync_nonzero flush.
