From 6e7a3f5244356ce079457cb3cfbc58ca01c00a2e Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Thu, 11 Jan 2018 08:24:17 +0000 Subject: [PATCH] drm/i915: Apply headless DMC workaround for CNL With firmware 1.07 having fixed the state corruption issue, we can enable the headless GT performance workaround for CNL as well. (Equivalent to b68763741aa2 ("drm/i915: Restore GT performance in headless mode with DMC loaded") on other affected platforms.)
