28	/** @page pg_vmmdev The VMM Device.
29	*
30	* The VMM device is a custom hardware device emulation for communicating with
31	* the guest additions.
32	*
33	* Whenever host wants to inform guest about something an IRQ notification will
34	* be raised.
35	*
36	* VMMDev PDM interface will contain the guest notification method.
37	*
38	* There is a 32 bit event mask which will be read by guest on an interrupt. A
39	* non zero bit in the mask means that the specific event occurred and requires
40	* processing on guest side.
41	*
42	* After reading the event mask guest must issue a generic request
43	* AcknowlegdeEvents.
44	*
45	* IRQ line is set to 1 (request) if there are unprocessed events, that is the
46	* event mask is not zero.
47	*
48	* After receiving an interrupt and checking event mask, the guest must process
49	* events using the event specific mechanism.
50	*
51	* That is if mouse capabilities were changed, guest will use
52	* VMMDev_GetMouseStatus generic request.
53	*
54	* Event mask is only a set of flags indicating that guest must proceed with a
55	* procedure.
56	*
57	* Unsupported events are therefore ignored. The guest additions must inform
58	* host which events they want to receive, to avoid unnecessary IRQ processing.
59	* By default no events are signalled to guest.
60	*
61	* This seems to be fast method. It requires only one context switch for an
62	* event processing.
63	*
64	*
65	* @section sec_vmmdev_heartbeat Heartbeat
66	*
67	* The heartbeat is a feature to monitor whether the guest OS is hung or not.
68	*
69	* The main kernel component of the guest additions, VBoxGuest, sets up a timer
70	* at a frequency returned by VMMDevReq_HeartbeatConfigure
71	* (VMMDevReqHeartbeat::cNsInterval, VMMDEV::cNsHeartbeatInterval) and performs
72	* a VMMDevReq_GuestHeartbeat request every time the timer ticks.
73	*
74	* The host side (VMMDev) arms a timer with a more distant deadline
75	* (VMMDEV::cNsHeartbeatTimeout), twice cNsHeartbeatInterval by default. Each
76	* time a VMMDevReq_GuestHeartbeat request comes in, the timer is rearmed with
77	* the same relative deadline. So, as long as VMMDevReq_GuestHeartbeat comes
78	* when they should, the host timer will never fire.
79	*
80	* When the timer fires, we consider the guest as hung / flatlined / dead.
81	* Currently we only LogRel that, but it's easy to extend this with an event in
82	* Main API.
83	*
84	* Should the guest reawaken at some later point, we LogRel that event and
85	* continue as normal. Again something which would merit an API event.
86	*
