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