Subject: [Intel-gfx] [PATCH 10/22] drm/syncobj: Allow use of dma-fence-proxy
Date: Wed, 20 May 2020 08:54:51 +0100 [thread overview]
Message-ID: <20200520075503.10388-10-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200520075503.10388-1-chris@chris-wilson.co.uk>
Allow the callers to supply a dma-fence-proxy for asynchronous waiting on
future fences.
