[Qemu-devel] [PATCH RFC v2 00/12] qemu: towards virtio-1 host support

[Cornelia Huck]

Hi,

here's the next version of my virtio-1 qemu patchset. Using virtio-1
virtio-blk and virtio-net devices with a guest kernel built from
<address@hidden> still seems to
work for the virtio-ccw transport.

Changes from v1:
- rebased against current master
- don't advertise VERSION_1 for all devices, make devices switch it on
  individually

Cornelia Huck (9):
  virtio: cull virtio_bus_set_vdev_features
  virtio: support more feature bits
  s390x/virtio-ccw: fix check for WRITE_FEAT
  virtio: introduce legacy virtio devices
  virtio: allow virtio-1 queue layout
  dataplane: allow virtio-1 devices
  s390x/virtio-ccw: support virtio-1 set_vq format
  virtio-net/virtio-blk: enable virtio 1.0
  s390x/virtio-ccw: enable virtio 1.0

Thomas Huth (3):
  linux-headers/virtio_config: Update with VIRTIO_F_VERSION_1
  s390x/css: Add a callback for when subchannel gets disabled
  s390x/virtio-ccw: add virtio set-revision call
