[Qemu-devel] [PATCH v3 0/2] qemu: ioeventfd for virtio-ccw.

[Cornelia Huck]

Here's the current version of my patch enabling ioeventfds for virtio-ccw.

The linux-headers patch only adds the new flag for ioeventfds.

Wiring up ioeventfds has improved performance drastically (up to twice
as fast for a simple dd). Notifier support is something we plan to do
next.

Please consider applying if this makes sense.

v2 -> v3:
- Adapt to changed ioeventfd interface again.
v1 -> v2:
- Adapt to changed ioeventfd interface.

Cornelia Huck (2):
  linux-headers: Update with ioeventfd changes.
  virtio-ccw: Wire up ioeventfd.
