From fdbdc7f325af9b42684fc6c7100cb57c52b31c4a Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 9 Dec 2013 23:29:35 -0800 Subject: rendercopy/bdw: Emit 3DSTATE_WM_HZ_OP. We don't want depth/stencil fast clears or HiZ resolves; we want normal drawing. Without this, the pixel pipeline doesn't work.
