81	/* Whenever host wants to inform guest about something
82	* an IRQ notification will be raised.
83	*
84	* VMMDev PDM interface will contain the guest notification method.
85	*
86	* There is a 32 bit event mask which will be read
87	* by guest on an interrupt. A non zero bit in the mask
88	* means that the specific event occured and requires
89	* processing on guest side.
90	*
91	* After reading the event mask guest must issue a
92	* generic request AcknowlegdeEvents.
93	*
94	* IRQ line is set to 1 (request) if there are unprocessed
95	* events, that is the event mask is not zero.
96	*
97	* After receiving an interrupt and checking event mask,
98	* the guest must process events using the event specific
99	* mechanism.
100	*
101	* That is if mouse capabilities were changed,
102	* guest will use VMMDev_GetMouseStatus generic request.
103	*
104	* Event mask is only a set of flags indicating that guest
105	* must proceed with a procedure.
106	*
107	* Unsupported events are therefore ignored.
108	* The guest additions must inform host which events they
109	* want to receive, to avoid unnecessary IRQ processing.
110	* By default no events are signalled to guest.
111	*
112	* This seems to be fast method. It requires
113	* only one context switch for an event processing.
