Subject: [PATCH 11/15] drm: add user fence support for atomic in fences
Date: Mon,  2 May 2022 18:37:18 +0200	[thread overview]
Message-ID: <20220502163722.3957-12-christian.koenig@amd.com> (raw)
In-Reply-To: <20220502163722.3957-1-christian.koenig@amd.com>

When the DRIVER_USER_FENCE flag is set we grab the user fence from the
sync file instead of the normal one.
