Subject: [PATCH 4.11 13/13] drm/i915: Disable decoupled MMIO
Date: Thu, 15 Jun 2017 19:54:47 +0200 [thread overview]
Message-ID: <20170615175426.707438318@linuxfoundation.org> (raw)
In-Reply-To: <20170615175426.075744317@linuxfoundation.org>
4.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kai Chen <kai.chen@intel.com>
commit 4c4c565513cca1c53a12956640b5915727431631 upstream.
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.
Fixes: 85ee17ebeedd ("drm/i915/bxt: Broxton decoupled MMIO")
