Subject: [PATCH 0/3] xen/virtio: support grant based virtio on x86

Message-ID: <20221006071500.15689-1-jgross@suse.com> (raw)

backend to be in dom0 in the case the guest kernel was built with
CONFIG_XEN_VIRTIO_FORCE_GRANT.
Juergen Gross (3):
xen/virtio: restructure xen grant dma setup
xen/virtio: use dom0 as default backend for
CONFIG_XEN_VIRTIO_FORCE_GRANT
xen/virtio: enable grant based virtio on x86
