Subject: [PATCH AUTOSEL 5.5 08/28] drm/amdgpu: add fbdev suspend/resume on gpu reset
Date: Thu, 26 Mar 2020 19:23:37 -0400 [thread overview]
Message-ID: <20200326232357.7516-8-sashal@kernel.org> (raw)
In-Reply-To: <20200326232357.7516-1-sashal@kernel.org>
From: Evan Quan <evan.quan@amd.com>
[ Upstream commit 063e768ebd27d3ec0d6908b7f8ea9b0a732b9949 ]
This can fix the baco reset failure seen on Navi10.
And this should be a low risk fix as the same sequence
is already used for system suspend/resume.
