|
|
# List properties associated with a device.
|
|
#
|
|
# @typename: the type name of a device
|
|
#
|
|
# Returns: a list of ObjectPropertyInfo describing a devices properties
|
|
#

# Additional arguments depend on the type.

# Add a device.

|
|
# Notes:
|
|
# 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.

# @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.

# 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
|
|
