[PATCH RFC v6 00/20] qemu: towards virtio-1 host support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



And yet another iteration of virtio-1 support in qemu, tested with the
latest virtio kernel patches. Find it at

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

Changes from v5:
- fixed stupid bug in "virtio: support more feature bits": we need to
  define a proper prop backend for 64 bit wide handling...
- don't negotiate revision 1 unless VERSION_1 is offered
- use 64 bit wide features in the whole of vhost (patch can probably be
  merged into the 64 bit extension for the rest of the code)

The bug I suspected in the revision-specific feature handling turned out
to be a messup on my side. There still seems to be something missing for
vhost-net to support virtio-1.

Cornelia Huck (17):
  virtio: cull virtio_bus_set_vdev_features
  virtio: feature bit manipulation helpers
  virtio: add feature checking helpers
  virtio: support more feature bits
  virtio: endianness checks for virtio 1.0 devices
  virtio: allow virtio-1 queue layout
  dataplane: allow virtio-1 devices
  s390x/virtio-ccw: support virtio-1 set_vq format
  virtio: disallow late feature changes for virtio-1
  virtio: allow to fail setting status
  s390x/virtio-ccw: enable virtio 1.0
  virtio-net: no writeable mac for virtio-1
  virtio-net: support longer header
  virtio-net: enable virtio 1.0
  virtio: support revision-specific features
  virtio-blk: revision specific feature bits
  vhost: 64 bit features

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
