Subject: [PATCH] drm/vc4: Return -EBUSY if there's already a pending flip event.
Date: Mon, 2 May 2016 15:25:21 -0400 [thread overview]
Message-ID: <1462217122-13071-1-git-send-email-robert.foss@collabora.com> (raw)
From: Robert Foss <robert.foss@collabora.com>
As per the docs, atomic_commit should return -EBUSY "if an asycnhronous
update is requested and there is an earlier update pending".
This patch is based on the rockchip patch below:
http://article.gmane.org/gmane.comp.video.dri.devel/151678
Note: This patch was resent as the original submission wasn't addressed
to the apparopriate recipients.
