Subject: [ 03/34] drm/radeon/evergreen+: wait for the MC to settle after MC blackout
Date: Thu, 7 Feb 2013 16:56:59 -0800 [thread overview]
Message-ID: <20130208004627.939261062@linuxfoundation.org> (raw)
In-Reply-To: <20130208004627.375461662@linuxfoundation.org>
3.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@amd.com>
commit ed39fadd6df01095378e499fac3674883f16b853 upstream.
Some chips seem to need a little delay after blacking out
the MC before the requests actually stop.
May fix:
