Subject: [PATCH 2/2] drm/virtio: set max_segment
Date: Tue, 18 Aug 2020 09:48:28 +0200 [thread overview]
Message-ID: <20200818074828.9509-3-kraxel@redhat.com> (raw)
In-Reply-To: <20200818074828.9509-1-kraxel@redhat.com>
When initializing gem objects call virtio_max_dma_size() to figure the
scatter list limit. Needed to make virtio-gpu work properly with SEV.
