Emitted when the guest makes a request to enter S4 state. There are three possible ways of having this event, as described here:
http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html I've decided to add a new event and make it indepedent of SHUTDOWN. This means that the SHUTDOWN event will eventually follow the SUSPEND_DISK event. I've choosen this way because of two reasons: 1. Having an indepedent event makes it possible to query for its existence by using query-events 2. In the future, we may allow the user to change what QEMU should do as a result of the guest entering S4. So it's a good idea to keep both events separated Signed-off-by: Luiz Capitulino <lcapitul...@redhat.com> --- This is on top of: [PATCH 0/4]: qmp: WAKEUP event related fixes QMP/qmp-events.txt | 14 ++++++++++++++ hw/acpi.c | 2 ++ monitor.c | 1 + monitor.h | 1 + 4 files changed, 18 insertions(+) diff --git a/QMP/qmp-events.txt b/QMP/qmp-events.txt index 2001a71..1c51bee 100644 --- a/QMP/qmp-events.txt +++ b/QMP/qmp-events.txt @@ -252,6 +252,20 @@ Example: { "event": "SUSPEND", "timestamp": { "seconds": 1344456160, "microseconds": 309119 } } +SUSPEND_DISK +------------ + +Emitted when the guest makes a request to enter S4 state. + +Data: None. + +Example: + +{ "event": "SUSPEND_DISK", + "timestamp": { "seconds": 1344456160, "microseconds": 309119 } } + +Note: QEMU shutdowns when entering S4 state. + VNC_CONNECTED ------------- diff --git a/hw/acpi.c b/hw/acpi.c index effc7ec..f7950be 100644 --- a/hw/acpi.c +++ b/hw/acpi.c @@ -22,6 +22,7 @@ #include "hw.h" #include "pc.h" #include "acpi.h" +#include "monitor.h" struct acpi_table_header { uint16_t _length; /* our length, not actual part of the hdr */ @@ -386,6 +387,7 @@ void acpi_pm1_cnt_write(ACPIREGS *ar, uint16_t val, char s4) break; default: if (sus_typ == s4) { /* S4 request */ + monitor_protocol_event(QEVENT_SUSPEND_DISK, NULL); qemu_system_shutdown_request(); } break; diff --git a/monitor.c b/monitor.c index 49dccfe..4f3c595 100644 --- a/monitor.c +++ b/monitor.c @@ -456,6 +456,7 @@ static const char *monitor_event_names[] = { [QEVENT_BLOCK_JOB_CANCELLED] = "BLOCK_JOB_CANCELLED", [QEVENT_DEVICE_TRAY_MOVED] = "DEVICE_TRAY_MOVED", [QEVENT_SUSPEND] = "SUSPEND", + [QEVENT_SUSPEND_DISK] = "SUSPEND_DISK", [QEVENT_WAKEUP] = "WAKEUP", [QEVENT_BALLOON_CHANGE] = "BALLOON_CHANGE", }; diff --git a/monitor.h b/monitor.h index 5f4de1b..4ef9a04 100644 --- a/monitor.h +++ b/monitor.h @@ -40,6 +40,7 @@ typedef enum MonitorEvent { QEVENT_BLOCK_JOB_CANCELLED, QEVENT_DEVICE_TRAY_MOVED, QEVENT_SUSPEND, + QEVENT_SUSPEND_DISK, QEVENT_WAKEUP, QEVENT_BALLOON_CHANGE, -- 1.7.11.2.249.g31c7954.dirty
