19	*
20	* The VMM device is a custom hardware device emulation for communicating with
21	* the guest additions.
22	*
23	* Whenever host wants to inform guest about something an IRQ notification will
24	* be raised.
25	*
26	* VMMDev PDM interface will contain the guest notification method.
27	*
28	* There is a 32 bit event mask which will be read by guest on an interrupt. A
29	* non zero bit in the mask means that the specific event occurred and requires
30	* processing on guest side.
31	*
32	* After reading the event mask guest must issue a generic request
33	* AcknowlegdeEvents.
34	*
35	* IRQ line is set to 1 (request) if there are unprocessed events, that is the
36	* event mask is not zero.
37	*
38	* After receiving an interrupt and checking event mask, the guest must process
39	* events using the event specific mechanism.
40	*
41	* That is if mouse capabilities were changed, guest will use
42	* VMMDev_GetMouseStatus generic request.
43	*
44	* Event mask is only a set of flags indicating that guest must proceed with a
45	* procedure.
46	*
47	* Unsupported events are therefore ignored. The guest additions must inform
48	* host which events they want to receive, to avoid unnecessary IRQ processing.
49	* By default no events are signalled to guest.
50	*
51	* This seems to be fast method. It requires only one context switch for an
52	* event processing.
53	*
54	*
55	* @section sec_vmmdev_heartbeat Heartbeat
56	*
57	* The heartbeat is a feature to monitor whether the guest OS is hung or not.
58	*
59	* The main kernel component of the guest additions, VBoxGuest, sets up a timer
60	* at a frequency returned by VMMDevReq_HeartbeatConfigure
61	* (VMMDevReqHeartbeat::cNsInterval, VMMDEV::cNsHeartbeatInterval) and performs
62	* a VMMDevReq_GuestHeartbeat request every time the timer ticks.
63	*
64	* The host side (VMMDev) arms a timer with a more distant deadline
65	* (VMMDEV::cNsHeartbeatTimeout), twice cNsHeartbeatInterval by default. Each
66	* time a VMMDevReq_GuestHeartbeat request comes in, the timer is rearmed with
67	* the same relative deadline. So, as long as VMMDevReq_GuestHeartbeat comes
68	* when they should, the host timer will never fire.
69	*
70	* When the timer fires, we consider the guest as hung / flatlined / dead.
71	* Currently we only LogRel that, but it's easy to extend this with an event in
72	* Main API.
73	*
74	* Should the guest reawaken at some later point, we LogRel that event and
75	* continue as normal. Again something which would merit an API event.
76	*
