Subject: [PATCH 07/17] drm/i915/gtt: Reorder aliasing_ppgtt fini
Date: Wed,  6 Jun 2018 07:27:00 +0100	[thread overview]
Message-ID: <20180606062710.29984-8-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20180606062710.29984-1-chris@chris-wilson.co.uk>

To allow ourselves to use a first class vma for the aliasing_ppgtt page
directory, we have to reorder the shutdown on module unload to remove
and unpin the aliasing_ppgtt before complaining about any objects left
in the GGTT.
