[Qemu-devel] [PATCH RFC 00/11] qemu: towards virtio-1 host support

[Cornelia Huck]

This patchset aims to get us some way to implement virtio-1 compliant
and transitional devices in qemu. Branch available at

git://github.com/cohuck/qemu virtio-1

I've mainly focused on:
- endianness handling
- extended feature bits
- virtio-ccw new/changed commands

Thanks go to Thomas for some preliminary work in this area.

I've been able to start guests both with and without the virtio-1 patches
in the linux guest patchset, with virtio-net and virtio-blk devices (with
and without dataplane). virtio-ccw only :) vhost, migration and loads of
other things have been ignored for now.

I'd like to know whether I walk into the right direction, so let's consider
this as a starting point.

Cornelia Huck (8):
  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
  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
