Wu Zhou e83ae3e664 dm: vm_event: init vm_event ... This patch adds vm_event sbuf and notification initialization. We have 2 types of event source: DM and HV, and they are slightly different: - Sbuf for DM event source is a memery page shared between threads. Event notifications are delivered by userspace eventfd. - While for hv event source, sbuf is a memery page shared with HV. Its address(GPA) is shared to HV through hypercall. Its notifications are generated by HV upcall, then delivered by kernel/userspace eventfd. A sbuf message path acts like a one way ‘tunnel’, so a data structure ‘vm_event_tunnel’ is created to organize those sbufs.
