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