Subject: [Intel-gfx] [PATCH 28/57] drm/i915: Wrap i915_request_use_semaphores()
Date: Mon,  1 Feb 2021 08:56:46 +0000
Message-ID: <20210201085715.27435-28-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20210201085715.27435-1-chris@chris-wilson.co.uk>

Wrap the query on whether the backend engine supports us emitting
semaphores to coordinate multiple requests.
