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