Hi, here's the qemu patch that implements the new adapter indicators ccw in virtio-ccw and injects adapter interrupts for the devices enabled for it. Cornelia Huck (1): s390/virtio-ccw: Adapter interrupt support. hw/s390x/css.c | 10 ++++++++ hw/s390x/css.h | 2 ++ hw/s390x/virtio-ccw.c | 66 ++++++++++++++++++++++++++++++++++++++++++++++++- hw/s390x/virtio-ccw.h |
