+# @device_add:
+#
+# @driver: the name of the new device's driver
+#
+# @bus: #optional the device's parent bus (device tree path)
+#
+# @id: the device's ID, must be unique
+#
+# 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.
+#
+# Since: 0.13
