So here's my current patchset for adding guest/host notifiers in virtio-ccw.

Patches can also be found at git://github.com/cohuck/qemu virtio-ccw-notifiers Cornelia Huck (3): linux-headers: Update with ioeventfd changes. virtio-ccw: Wire up ioeventfd. virtio-ccw: Wire up guest and host notifies. hw/s390x/css.c | 2 +- hw/s390x/css.h | 1 + hw/s390x/virtio-ccw.c | 203 +++++++++++++++++++++++++++++++++++++++++++++ hw/s390x/virtio-ccw.h | 8 ++ linux-headers/linux/kvm.h | 3 + target-s390x/cpu.h | 16 ++++ target-s390x/kvm.c | 19 +++++ 7 files changed, 251 insertions(+), 1 deletion(-) -- 1.7.9.5
