Introduce a new callback on subchannel to handle ccw-request. Realize the callback in vfio-ccw device. Besides, resort to the event notifier handler to handling the ccw-request results. 1. Pread the I/O results via MMIO region. 2. Update the scsw info to guest. 3. Inject an I/O interrupt to notify guest the I/O result.
