Subject: [Intel-gfx] [PATCH 2/2] drm/i915/gvt: Wean gvt off using dev_priv
Date: Fri, 17 Jan 2020 15:35:54 +0000	[thread overview]
Message-ID: <20200117153554.3104278-2-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200117153554.3104278-1-chris@chris-wilson.co.uk>

Teach gvt to use intel_gt directly as it currently assumes direct HW
access.
