##
# = Other events
##

##
# @SHUTDOWN:
#
# Emitted when the virtual machine has shut down, indicating that qemu is
# about to exit.
#
# @guest: If true, the shutdown was triggered by a guest request (such as
# a guest-initiated ACPI shutdown request or other hardware-specific action)
# rather than a host request (such as sending qemu a SIGINT). (since 2.10)
#
# Note: If the command-line option "-no-shutdown" has been specified, qemu will
# not exit, and a STOP event will eventually follow the SHUTDOWN event
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "SHUTDOWN", "data": { "guest": true },
#      "timestamp": { "seconds": 1267040730, "microseconds": 682951 } }
#
##
{ 'event': 'SHUTDOWN', 'data': { 'guest': 'bool' } }

##
# @POWERDOWN:
#
# Emitted when the virtual machine is powered down through the power control
# system, such as via ACPI.
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "POWERDOWN",
#      "timestamp": { "seconds": 1267040730, "microseconds": 682951 } }
#
##
{ 'event': 'POWERDOWN' }

##
# @RESET:
#
# Emitted when the virtual machine is reset
#
# @guest: If true, the reset was triggered by a guest request (such as
# a guest-initiated ACPI reboot request or other hardware-specific action)
# rather than a host request (such as the QMP command system_reset).
# (since 2.10)
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "RESET", "data": { "guest": false },
#      "timestamp": { "seconds": 1267041653, "microseconds": 9518 } }
#
##
{ 'event': 'RESET', 'data': { 'guest': 'bool' } }

##
# @STOP:
#
# Emitted when the virtual machine is stopped
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "STOP",
#      "timestamp": { "seconds": 1267041730, "microseconds": 281295 } }
#
##
{ 'event': 'STOP' }

##
# @RESUME:
#
# Emitted when the virtual machine resumes execution
#
# Since: 0.12.0
#
# Example:
#
# <- { "event": "RESUME",
#      "timestamp": { "seconds": 1271770767, "microseconds": 582542 } }
#
##
{ 'event': 'RESUME' }

##
# @SUSPEND:
#
# Emitted when guest enters a hardware suspension state, for example, S3 state,
# which is sometimes called standby state
#
# Since: 1.1
#
# Example:
#
# <- { "event": "SUSPEND",
#      "timestamp": { "seconds": 1344456160, "microseconds": 309119 } }
#
##
{ 'event': 'SUSPEND' }

##
# @SUSPEND_DISK:
#
# Emitted when guest enters a hardware suspension state with data saved on
# disk, for example, S4 state, which is sometimes called hibernate state
#
# Note: QEMU shuts down (similar to event @SHUTDOWN) when entering this state
#
# Since: 1.2
#
# Example:
#
# <-   { "event": "SUSPEND_DISK",
#        "timestamp": { "seconds": 1344456160, "microseconds": 309119 } }
#
##
{ 'event': 'SUSPEND_DISK' }

##
# @WAKEUP:
#
# Emitted when the guest has woken up from suspend state and is running
#
# Since: 1.1
#
# Example:
#
# <- { "event": "WAKEUP",
#      "timestamp": { "seconds": 1344522075, "microseconds": 745528 } }
#
##
{ 'event': 'WAKEUP' }

##
# @RTC_CHANGE:
#
# Emitted when the guest changes the RTC time.
#
# @offset: offset between base RTC clock (as specified by -rtc base), and
#          new RTC clock value
#
# Note: This event is rate-limited.
#
# Since: 0.13.0
#
# Example:
#
# <-   { "event": "RTC_CHANGE",
#        "data": { "offset": 78 },
#        "timestamp": { "seconds": 1267020223, "microseconds": 435656 } }
#
##
{ 'event': 'RTC_CHANGE',
  'data': { 'offset': 'int' } }

##
# @WATCHDOG:
#
# Emitted when the watchdog device's timer is expired
#
# @action: action that has been taken
#
# Note: If action is "reset", "shutdown", or "pause" the WATCHDOG event is
# followed respectively by the RESET, SHUTDOWN, or STOP events
#
# Note: This event is rate-limited.
#
# Since: 0.13.0
#
# Example:
#
# <- { "event": "WATCHDOG",
#      "data": { "action": "reset" },
#      "timestamp": { "seconds": 1267061043, "microseconds": 959568 } }
#
##
{ 'event': 'WATCHDOG',
  'data': { 'action': 'WatchdogExpirationAction' } }

##
# @DEVICE_DELETED:
#
# Emitted whenever the device removal completion is acknowledged by the guest.
# At this point, it's safe to reuse the specified device ID. Device removal can
# be initiated by the guest or by HMP/QMP commands.
#
# @device: device name
#
# @path: device path
#
# Since: 1.5
#
# Example:
#
# <- { "event": "DEVICE_DELETED",

#
##
{ 'event': 'DEVICE_DELETED',
  'data': { '*device': 'str', 'path': 'str' } }

##
# @NIC_RX_FILTER_CHANGED:
#
# Emitted once until the 'query-rx-filter' command is executed, the first event
# will always be emitted
#
# @name: net client name
#
# @path: device path
#
# Since: 1.6
#
# Example:
#
# <- { "event": "NIC_RX_FILTER_CHANGED",
#      "data": { "name": "vnet0",
#                "path": "/machine/peripheral/vnet0/virtio-backend" },

#    }
#
##
{ 'event': 'NIC_RX_FILTER_CHANGED',
  'data': { '*name': 'str', 'path': 'str' } }

# @VNC_CONNECTED:
#
# Emitted when a VNC client establishes a connection
#
# @server: server information
#
# @client: client information
#
# Note: This event is emitted before any authentication takes place, thus

#      "data": {
