|
---|
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.
|
---|
