virtio-pci: initial virtio 1.0 support
This is somewhat functional. With this, and linux driver from my tree, I was able to use virtio net as virtio 1.0 device for light browsing. At the moment, dataplane and vhost code is still missing. Based on Cornelia's virtio 1.0 patchset: Date: Thu, 11 Dec 2014 14:25:02 +0100 From: Cornelia Huck <cornelia.huck@de.ibm.com> To: virtualization@lists.linux-foundation.org, qemu-devel@nongnu.org Cc: rusty@rustcorp.com.au, thuth@linux.vnet.ibm.com, mst@redhat.com, Cornelia Huck <cornelia.huck@de.ibm.com> Subject: [PATCH RFC v6 00/20] qemu: towards virtio-1 host support Message-Id: <1418304322-7546-1-git-send-email-cornelia.huck@de.ibm.com> which is itself still missing some core bits.
