commit 97fe3c1c860978c7a649cba93a55fa497010ccc1 Author: Rodrigo Vivi <rodrigo.vivi@intel.com> Date: Wed Nov 5 15:48:14 2014 -0800 sna: Use VMask in 3DSTATE_PS Using dispatch mask cause hangs waiting PS Done on some cases like bug #83207, with larger screen or when scaling it. Also mesa uses VMask instead of Dmask for 3DSTATE_PS because in some cases they were getting incorrect derivatives for subspans.
