88	/* Whenever host wants to inform guest about something
89	* an IRQ notification will be raised.
90	*
91	* VMMDev PDM interface will contain the guest notification method.
92	*
93	* There is a 32 bit event mask which will be read
94	* by guest on an interrupt. A non zero bit in the mask
95	* means that the specific event occurred and requires
96	* processing on guest side.
97	*
98	* After reading the event mask guest must issue a
99	* generic request AcknowlegdeEvents.
100	*
101	* IRQ line is set to 1 (request) if there are unprocessed
102	* events, that is the event mask is not zero.
103	*
104	* After receiving an interrupt and checking event mask,
105	* the guest must process events using the event specific
106	* mechanism.
107	*
108	* That is if mouse capabilities were changed,
109	* guest will use VMMDev_GetMouseStatus generic request.
110	*
111	* Event mask is only a set of flags indicating that guest
112	* must proceed with a procedure.
113	*
114	* Unsupported events are therefore ignored.
115	* The guest additions must inform host which events they
116	* want to receive, to avoid unnecessary IRQ processing.
117	* By default no events are signalled to guest.
118	*
119	* This seems to be fast method. It requires
120	* only one context switch for an event processing.
