From b29f92daec59a4181a45175b6bfc6e636c57fb33 Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Mon, 19 Oct 2015 15:08:28 -0700 Subject: [PATCH] i965: Add mask_control_ex field and handle it in compaction. Documentation is sparse, but it appears to have existed on G45 and ILK as a second bit extension of the mask_control field. Setting the pair of bits to 0b11 enables "NoCMask".
