From 0051c10acabb631cfd439eae73289e6e4c39b2b7 Mon Sep 17 00:00:00 2001 From: Kai Chen Date: Tue, 23 May 2017 14:58:11 -0700 Subject: [PATCH] drm/i915: Disable decoupled MMIO The decoupled MMIO feature doesn't work as intended by HW team. Enabling it with forcewake will only make debugging efforts more difficult, so let's disable it.
