VMMDev: The host does not _use_ the full-state-mouse-protocol, it either 'supports' or 'implements' it, going with the former: s/VMMDEV_MOUSE_HOST_USES_FULL_STATE_PROTOCOL/VMMDEV_MOUSE_HOST_SUPPORTS_FULL_STATE_PROTOCOL/ bugref:10285

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 *
