91/* Whenever host wants to inform guest about something
92 * an IRQ notification will be raised.
93 *
94 * VMMDev PDM interface will contain the guest notification method.
95 *
96 * There is a 32 bit event mask which will be read
97 * by guest on an interrupt. A non zero bit in the mask
98 * means that the specific event occurred and requires
99 * processing on guest side.
100 *
101 * After reading the event mask guest must issue a
102 * generic request AcknowlegdeEvents.
103 *
104 * IRQ line is set to 1 (request) if there are unprocessed
105 * events, that is the event mask is not zero.
106 *
107 * After receiving an interrupt and checking event mask,
108 * the guest must process events using the event specific
109 * mechanism.
110 *
111 * That is if mouse capabilities were changed,
112 * guest will use VMMDev_GetMouseStatus generic request.
113 *
114 * Event mask is only a set of flags indicating that guest
115 * must proceed with a procedure.
116 *
117 * Unsupported events are therefore ignored.
118 * The guest additions must inform host which events they
119 * want to receive, to avoid unnecessary IRQ processing.
120 * By default no events are signalled to guest.
121 *
122 * This seems to be fast method. It requires
123 * only one context switch for an event processing.
