Conforms to the event specification defined in the QMP/qmp-events.txt file.
Please, note the following details: o The event should be emitted only by devices which support the eject operation, which currently are: CDROMs (IDE and SCSI) and floppies o Human monitor commands "eject" and "change" also cause the event to be emitted o The event is only emitted when there's a tray transition from closed to opened. To implement this in the human monitor, we only emit the event if the device is removable and a media is present Signed-off-by: Luiz Capitulino <lcapitul...@redhat.com> --- block.c | 12 ++++++++++++ block.h | 1 + blockdev.c | 5 +++++ monitor.c | 3 +++ monitor.h | 1 + 5 files changed, 22 insertions(+), 0 deletions(-) diff --git a/block.c b/block.c index f5014cf..dbe813b 100644 --- a/block.c +++ b/block.c @@ -1656,6 +1656,15 @@ int bdrv_is_allocated(BlockDriverState *bs, int64_t sector_num, int nb_sectors, return bs->drv->bdrv_is_allocated(bs, sector_num, nb_sectors, pnum); } +void bdrv_eject_mon_event(const BlockDriverState *bdrv) +{ + QObject *data; + + data = qobject_from_jsonf("{ 'device': %s }", bdrv->device_name); + monitor_protocol_event(QEVENT_BLOCK_MEDIA_EJECT, data); + qobject_decref(data); +} + void bdrv_error_mon_event(const BlockDriverState *bdrv, BlockMonEventAction action, int is_read) { @@ -2770,6 +2779,9 @@ int bdrv_eject(BlockDriverState *bs, int eject_flag) ret = 0; } if (ret >= 0) { + if (eject_flag && !bs->tray_open) { + bdrv_eject_mon_event(bs); + } bs->tray_open = eject_flag; } diff --git a/block.h b/block.h index 1f58eab..e4053dd 100644 --- a/block.h +++ b/block.h @@ -50,6 +50,7 @@ typedef enum { BDRV_ACTION_REPORT, BDRV_ACTION_IGNORE, BDRV_ACTION_STOP } BlockMonEventAction; +void bdrv_eject_mon_event(const BlockDriverState *bdrv); void bdrv_error_mon_event(const BlockDriverState *bdrv, BlockMonEventAction action, int is_read); void bdrv_info_print(Monitor *mon, const QObject *data); diff --git a/blockdev.c b/blockdev.c index 6e0eb83..5fd0043 100644 --- a/blockdev.c +++ b/blockdev.c @@ -661,6 +661,11 @@ static int eject_device(Monitor *mon, BlockDriverState *bs, int force) return -1; } } + + if (bdrv_is_removable(bs) && bdrv_is_inserted(bs)) { + bdrv_eject_mon_event(bs); + } + bdrv_close(bs); return 0; } diff --git a/monitor.c b/monitor.c index f63cce0..4a81467 100644 --- a/monitor.c +++ b/monitor.c @@ -450,6 +450,9 @@ void monitor_protocol_event(MonitorEvent event, QObject *data) case QEVENT_VNC_DISCONNECTED: event_name = "VNC_DISCONNECTED"; break; + case QEVENT_BLOCK_MEDIA_EJECT: + event_name = "BLOCK_MEDIA_EJECT"; + break; case QEVENT_BLOCK_IO_ERROR: event_name = "BLOCK_IO_ERROR"; break; diff --git a/monitor.h b/monitor.h index 4f2d328..7a04137 100644 --- a/monitor.h +++ b/monitor.h @@ -29,6 +29,7 @@ typedef enum MonitorEvent { QEVENT_VNC_CONNECTED, QEVENT_VNC_INITIALIZED, QEVENT_VNC_DISCONNECTED, + QEVENT_BLOCK_MEDIA_EJECT, QEVENT_BLOCK_IO_ERROR, QEVENT_RTC_CHANGE, QEVENT_WATCHDOG, -- 1.7.4.4
