96	/* Whenever host wants to inform guest about something
97	* an IRQ notification will be raised.
98	*
99	* VMMDev PDM interface will contain the guest notification method.
100	*
101	* There is a 32 bit event mask which will be read
102	* by guest on an interrupt. A non zero bit in the mask
103	* means that the specific event occurred and requires
104	* processing on guest side.
105	*
106	* After reading the event mask guest must issue a
107	* generic request AcknowlegdeEvents.
108	*
109	* IRQ line is set to 1 (request) if there are unprocessed
110	* events, that is the event mask is not zero.
111	*
112	* After receiving an interrupt and checking event mask,
113	* the guest must process events using the event specific
114	* mechanism.
115	*
116	* That is if mouse capabilities were changed,
117	* guest will use VMMDev_GetMouseStatus generic request.
118	*
119	* Event mask is only a set of flags indicating that guest
120	* must proceed with a procedure.
121	*
122	* Unsupported events are therefore ignored.
123	* The guest additions must inform host which events they
124	* want to receive, to avoid unnecessary IRQ processing.
125	* By default no events are signalled to guest.
126	*
127	* This seems to be fast method. It requires
128	* only one context switch for an event processing.
