Subject: [PATCH v7 2/3] virtio-gpu: add VIRTIO_GPU_F_RESOURCE_UUID feature
Date: Tue, 18 Aug 2020 16:13:42 +0900	[thread overview]
Message-ID: <20200818071343.3461203-3-stevensd@chromium.org> (raw)
In-Reply-To: <20200818071343.3461203-1-stevensd@chromium.org>

This feature allows the guest to request a UUID from the host for a
particular virtio_gpu resource. The UUID can then be shared with other
virtio devices, to allow the other host devices to access the
virtio_gpu's corresponding host resource.
