[Qemu-devel] [PATCH 0/3] dataplane: introduce virtio-blk.iothread property

[Stefan Hajnoczi <stefanha@redhat.com>]

Up until now the virtio-blk x-data-plane and x-iothread features have been
experimental.  It's time to commit to a final command-line interface:

  qemu -object iothread,id=iothread0 \
       -drive if=none,id=drive0,file=test.qcow2,format=qcow2 \
       -device virtio-blk-pci,iothread=iothread0,drive=drive0

The iothread=<iothread> property associates a virtio-blk-pci instance with an
IOThread.  If the iothread property is not given, the non-dataplane code path
is used.  This means dataplane is not the default yet.

The x-data-plane=on|off property is now obsolete but will be kept around for at
least another release cycle to give users a chance to migrate.

Stefan Hajnoczi (3):
  virtio-blk: replace x-iothread with iothread link property
  qdev: drop iothread property type
  virtio-blk: remove need for explicit x-data-plane=on option
