Subject: [PATCH 1/2] drm/i915: Disable decoupled MMIO
Date: Tue, 23 May 2017 14:58:11 -0700 [thread overview]
Message-ID: <20170523215812.18328-2-kai.chen@intel.com> (raw)
In-Reply-To: <20170523215812.18328-1-kai.chen@intel.com>
From: Kai Chen <kai.chen@intel.com>
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.
