Subject: [Intel-gfx] [PATCH v9 67/70] drm/i915: Add ww context to prepare_(read/write)
Date: Tue, 23 Mar 2021 16:50:56 +0100	[thread overview]
Message-ID: <20210323155059.628690-68-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20210323155059.628690-1-maarten.lankhorst@linux.intel.com>

This will allow us to explicitly pass the ww to pin_pages, when it starts taking it.
