##
# @qmp_capabilities:
#
# Enable QMP capabilities.
#
# Arguments:
#
# @enable: An optional list of QMPCapability values to enable.  The
#          client must not enable any capability that is not
#          mentioned in the QMP greeting message.  If the field is not
#          provided, it means no QMP capabilities will be enabled.
#          (since 2.12)
#
# Example:
#
# -> { "execute": "qmp_capabilities",
#      "arguments": { "enable": [ "oob" ] } }
# <- { "return": {} }
#
# Notes: This command is valid exactly when first connecting: it must be
#        issued before any other command will be accepted, and will fail once the
#        monitor is accepting other commands. (see qemu docs/interop/qmp-spec.txt)
#
#        The QMP client needs to explicitly enable QMP capabilities, otherwise
#        all the QMP capabilities will be turned off by default.
#
# Since: 0.13

##
# @QMPCapability:
#
# Enumeration of capabilities to be advertised during initial client
# connection, used for agreeing on particular QMP extension behaviors.
#
# @oob: QMP ability to support out-of-band requests.
#       (Please refer to qmp-spec.txt for more information on OOB)

##
# @VersionInfo:
#
# A description of QEMU's version.
#
# @qemu: The version of QEMU.  By current convention, a micro
#        version of 50 signifies a development branch.  A micro version
#        greater than or equal to 90 signifies a release candidate for
#        the next minor version.  A micro version of less than 50
#        signifies a stable release.
#
# @package: QEMU will always set this field to an empty string.  Downstream
#           versions of QEMU should set this to a non-empty string.  The
#           exact format depends on the downstream however it highly
#           recommended that a unique name is used.
#
# Since: 0.14.0

# @query-version:

# Returns: A @VersionInfo object describing the current version of QEMU.
#
# Since: 0.14.0
#
# Example:
#
# -> { "execute": "query-version" }
# <- {
#       "return":{
#          "qemu":{

# @query-commands:
#
# Return a list of supported QMP commands by this server

#
# Since: 0.14.0
#
# Example:
#
# -> { "execute": "query-commands" }

#
# Information about a QMP event
#
# @name: The event name
#
# Since: 1.2.0
##
{ 'struct': 'EventInfo', 'data': {'name': 'str'} }

##
# @query-events:
#
# Return information on QMP events.
#
# Features:
# @deprecated: This command is deprecated, because its output doesn't
#     reflect compile-time configuration.  Use 'query-qmp-schema'
#     instead.
#
# Returns: A list of @EventInfo.
#
# Since: 1.2.0

# Example:
#
# -> { "execute": "query-events" }

##
# @quit:
#
# This command will cause the QEMU process to exit gracefully.  While every
# attempt is made to send the QMP response before terminating, this is not
# guaranteed.  When using this interface, a premature EOF would not be
# unexpected.
#
# Since: 0.14.0
#
# Example:
#
# -> { "execute": "quit" }
# <- { "return": {} }
##

##
# @MonitorMode:
#
# An enumeration of monitor modes.
#

#
# @pretty:      Enables pretty printing (QMP only)
#
# @chardev:     Name of a character device to expose the monitor on
