81/* Whenever host wants to inform guest about something
82 * an IRQ notification will be raised.
83 *
84 * VMMDev PDM interface will contain the guest notification method.
85 *
86 * There is a 32 bit event mask which will be read
87 * by guest on an interrupt. A non zero bit in the mask
88 * means that the specific event occurred and requires
89 * processing on guest side.
90 *
91 * After reading the event mask guest must issue a
92 * generic request AcknowlegdeEvents.
93 *
94 * IRQ line is set to 1 (request) if there are unprocessed
95 * events, that is the event mask is not zero.
96 *
97 * After receiving an interrupt and checking event mask,
98 * the guest must process events using the event specific
99 * mechanism.
100 *
101 * That is if mouse capabilities were changed,
102 * guest will use VMMDev_GetMouseStatus generic request.
103 *
104 * Event mask is only a set of flags indicating that guest
105 * must proceed with a procedure.
106 *
107 * Unsupported events are therefore ignored.
108 * The guest additions must inform host which events they
109 * want to receive, to avoid unnecessary IRQ processing.
110 * By default no events are signalled to guest.
111 *
112 * This seems to be fast method. It requires
113 * only one context switch for an event processing.
