Subject: [PATCH 4.4 22/40] drm/msm: Grab a vblank reference when waiting for commit_done
Date: Thu, 20 Dec 2018 10:18:34 +0100 [thread overview]
Message-ID: <20181220085827.355559756@linuxfoundation.org> (raw)
In-Reply-To: <20181220085826.212663515@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 3b712e43e3876b42b38321ecf790a1f5fe59c834 ]
Similar to the atomic helpers, we should enable vblank while we're
waiting for the commit to finish. DPU needs this, MDP5 seems to work
fine without it.
