72/* Whenever host wants to inform guest about something
73 * an IRQ notification will be raised.
74 *
75 * VMMDev PDM interface will contain the guest notification method.
76 *
77 * There is a 32 bit event mask which will be read
78 * by guest on an interrupt. A non zero bit in the mask
79 * means that the specific event occured and requires
80 * processing on guest side.
81 *
82 * After reading the event mask guest must issue a
83 * generic request AcknowlegdeEvents.
84 *
85 * IRQ line is set to 1 (request) if there are unprocessed
86 * events, that is the event mask is not zero.
87 *
88 * After receiving an interrupt and checking event mask,
89 * the guest must process events using the event specific
90 * mechanism.
91 *
92 * That is if mouse capabilities were changed,
93 * guest will use VMMDev_GetMouseStatus generic request.
94 *
95 * Event mask is only a set of flags indicating that guest
96 * must proceed with a procedure.
97 *
98 * Unsupported events are therefore ignored.
99 * The guest additions must inform host which events they
100 * want to receive, to avoid unnecessary IRQ processing.
101 * By default no events are signalled to guest.
102 *
103 * This seems to be fast method. It requires
104 * only one context switch for an event processing.
