From 841526b7bbcaeda5b3b59871ad47596d14db4134 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Thu, 30 May 2019 16:40:14 -0700 Subject: [PATCH] drm/i915/ehl: Update MOCS table for EHL MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit EHL defines two new MOCS table entries but is otherwise compatible with the ICL MOCS table. These table entries (16 and 17) should still be considered unused for ICL and as such their behavior remains undefined for that platform.
