Hi, here's the guest driver support for adapter interrupts in virtio-ccw.
We use one summary indicator per page of indicators. For each device, we try to find a space in an indicator where all of its virtqueues fit. Locking probably needs some more love, but it seems to work fine so far. Cornelia Huck (2): KVM: s390: virtio-ccw: Handle command rejects.
