[Qemu-devel] [PATCH 0/2] virtio-ccw: Add notifiers support.

(Also to be found on git://github.com/cohuck/qemu virtio-ccw-notifiers)

As ioeventfd support for virtio-ccw is now upstream in the Linux kernel,
here's the exploiter in qemu for it.

Patch 1 uses the new ioeventfd implementation. Patch 2 wires up the
notifiers; guest notifiers using ioeventfd, host notifiers falling
back to qemu injecting interrupts as we don't have irqfd for s390 yet.
(I plan to implement that on top of adapter interrupts, which is the next
thing I'll takle.)

I'd like to get this into 1.6, so feedback is welcome.

Cornelia Huck (2):
  virtio-ccw: Wire up ioeventfd.
  virtio-ccw: Wire up guest and host notifies.
