{ 'include': 'qom.json' }
##
# @device-list-properties:
#
# List properties associated with a device.
#
# @typename: the type name of a device
#
# Returns: a list of ObjectPropertyInfo describing a devices properties
#
# Note: objects can create properties at runtime, for example to describe
# links between different devices and/or objects. These properties
# are not included in the output of this command.
#
# Since: 1.2
##
{ 'command': 'device-list-properties',
'data': { 'typename': 'str'},
'returns': [ 'ObjectPropertyInfo' ] }
##
# @device_add:
#
# Add a device.
#
# @driver: the name of the new device's driver
#
# @bus: the device's parent bus (device tree path)
#
# @id: the device's ID, must be unique
#
# Features:
# @json-cli: If present, the "-device" command line option supports JSON
# syntax with a structure identical to the arguments of this
# command.
# @json-cli-hotplug: If present, the "-device" command line option supports JSON
# syntax without the reference counting leak that broke
# hot-unplug
#
# Notes:
#
# Additional arguments depend on the type.
#
# 1. For detailed information about this command, please refer to the
# 'docs/qdev-device-use.txt' file.
#
# 2. It's possible to list device properties by running QEMU with the
# "-device DEVICE,help" command-line argument, where DEVICE is the
# device's name
#
# Example:
#
# -> { "execute": "device_add",
# "arguments": { "driver": "e1000", "id": "net1",
# "bus": "pci.0",
# "mac": "52:54:00:12:34:56" } }
# <- { "return": {} }
#
# TODO: This command effectively bypasses QAPI completely due to its
# "additional arguments" business. It shouldn't have been added to
# the schema in this form. It should be qapified properly, or
# replaced by a properly qapified command.
#
# Since: 0.13
##
{ 'command': 'device_add',
'data': {'driver': 'str', '*bus': 'str', '*id': 'str'},
'gen': false, # so we can get the additional arguments
'features': ['json-cli', 'json-cli-hotplug'] }
##
# @device_del:
#
# Remove a device from a guest
#
# @id: the device's ID or QOM path
#
# Returns: Nothing on success
# If @id is not a valid device, DeviceNotFound
#
# Notes: When this command completes, the device may not be removed from the
# guest. Hot removal is an operation that requires guest cooperation.
# This command merely requests that the guest begin the hot removal
# process. Completion of the device removal process is signaled with a
# DEVICE_DELETED event. Guest reset will automatically complete removal
# for all devices. If a guest-side error in the hot removal process is
# detected, the device will not be removed and a DEVICE_UNPLUG_GUEST_ERROR
# event is sent. Some errors cannot be detected.
#
# Since: 0.14
#
# Examples:
#
# -> { "execute": "device_del",
# "arguments": { "id": "net1" } }
# <- { "return": {} }
#
# -> { "execute": "device_del",
# "arguments": { "id": "/machine/peripheral-anon/device[0]" } }
# <- { "return": {} }
#
##
{ 'command': 'device_del', 'data': {'id': 'str'} }
##
# @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: the device's ID if it has one
#
# @path: the device's QOM path
#
# Since: 1.5
#
# Example:
#
# <- { "event": "DEVICE_DELETED",
# "data": { "device": "virtio-net-pci-0",
# "path": "/machine/peripheral/virtio-net-pci-0" },
# "timestamp": { "seconds": 1265044230, "microseconds": 450486 } }
#
##
{ 'event': 'DEVICE_DELETED',
'data': { '*device': 'str', 'path': 'str' } }
##
# @DEVICE_UNPLUG_GUEST_ERROR:
#
# Emitted when a device hot unplug fails due to a guest reported error.
#
# @device: the device's ID if it has one
#
# @path: the device's QOM path
#
# Since: 6.2
#
# Example:
#
# <- { "event": "DEVICE_UNPLUG_GUEST_ERROR",
# "data": { "device": "core1",
# "path": "/machine/peripheral/core1" },
# "timestamp": { "seconds": 1615570772, "microseconds": 202844 } }
