From 7c50f9903f58ef04ff393505a383d06f499f1fdc Mon Sep 17 00:00:00 2001 From: Nanley Chery Date: Tue, 7 Mar 2017 11:17:05 -0800 Subject: intel: Correct the BDW surface state size The PRMs state that this packet is 16 DWORDS long. Ensure that the last three DWORDS are zeroed as required by the hardware when allocating a null surface state.
