76/* Whenever host wants to inform guest about something
77 * an IRQ notification will be raised.
78 *
79 * VMMDev PDM interface will contain the guest notification method.
80 *
81 * There is a 32 bit event mask which will be read
82 * by guest on an interrupt. A non zero bit in the mask
83 * means that the specific event occured and requires
84 * processing on guest side.
85 *
86 * After reading the event mask guest must issue a
87 * generic request AcknowlegdeEvents.
88 *
89 * IRQ line is set to 1 (request) if there are unprocessed
90 * events, that is the event mask is not zero.
91 *
92 * After receiving an interrupt and checking event mask,
93 * the guest must process events using the event specific
94 * mechanism.
95 *
96 * That is if mouse capabilities were changed,
97 * guest will use VMMDev_GetMouseStatus generic request.
98 *
99 * Event mask is only a set of flags indicating that guest
100 * must proceed with a procedure.
101 *
102 * Unsupported events are therefore ignored.
103 * The guest additions must inform host which events they
104 * want to receive, to avoid unnecessary IRQ processing.
105 * By default no events are signalled to guest.
106 *
107 * This seems to be fast method. It requires
108 * only one context switch for an event processing.
