Subject: [PATCH 01/12] HACK: increase timeout for drm_atomic_helper_wait_for_vblanks
Date: Tue, 3 Jul 2018 11:02:12 +0100	[thread overview]
Message-ID: <1530612152-27555-2-git-send-email-dkos@cadence.com> (raw)
In-Reply-To: <1530612152-27555-1-git-send-email-dkos@cadence.com>

From: Quentin Schulz <quentin.schulz@free-electrons.com>

Due to the DP IP being simulated in a different and way slower way than
the rest of the hardware, increase the timeout in
drm_atomic_helper_wait_for_vblanks so that we don't miss the vblank
event.
