Subject: [PATCH v2 2/2] drm/virtio: set max_segment
Date: Tue, 18 Aug 2020 11:20:17 +0200 [thread overview]
Message-ID: <20200818092017.26290-3-kraxel@redhat.com> (raw)
In-Reply-To: <20200818092017.26290-1-kraxel@redhat.com>
When initializing call virtio_max_dma_size() to figure the scatter list
limit. Needed to make virtio-gpu work properly with SEV.
v2: place max_segment in drm driver not gem object.
