+=== Comments ===
+
Comments are allowed; anything between an unquoted # and the following
-newline is ignored. Although there is not yet a documentation
-generator, a form of stylized comments has developed for consistently
-documenting details about an expression and when it was added to the
-schema. The documentation is delimited between two lines of ##, then
-the first line names the expression, an optional overview is provided,
-then individual documentation about each member of 'data' is provided,
-and finally, a 'Since: x.y.z' tag lists the release that introduced
-the expression. Optional members are tagged with the phrase
-'#optional', often with their default value; and extensions added
-after the expression was first released are also given a '(since
-x.y.z)' comment. For example:
-
- ##
- # @BlockStats:
- #
- # Statistics of a virtual block device or a block backing device.
- #
- # @device: #optional If the stats are for a virtual block device, the name
- # corresponding to the virtual block device.
- #
- # @stats: A @BlockDeviceStats for the device.
- #
- # @parent: #optional This describes the file block device if it has one.
- #
- # @backing: #optional This describes the backing block device if it has one.
- # (Since 2.0)
- #
- # Since: 0.14.0
- ##
- { 'struct': 'BlockStats',
- 'data': {'*device': 'str', 'stats': 'BlockDeviceStats',
- '*parent': 'BlockStats',
- '*backing': 'BlockStats'} }
+newline is ignored.
+
+A multi-line comment that starts and ends with a '##' line is a
+documentation comment. These are parsed by the documentation
+generator, which recognizes certain markup detailed below.
+
+
+==== Documentation markup ====
+
+Comment text starting with '=' is a section title:
+
+ # = Section title
+
+Double the '=' for a subsection title:
+
+ # == Subection title
+
+'|' denotes examples:
+
+ # | Text of the example, may span
+ # | multiple lines
+
+'*' starts an itemized list:
+
+ # * First item, may span
+ # multiple lines
+ # * Second item
+
+You can also use '-' instead of '*'.
+
+A decimal number followed by '.' starts a numbered list:
+
+ # 1. First item, may span
+ # multiple lines
+ # 2. Second item
+
+The actual number doesn't matter. You could even use '*' instead of
+'2.' for the second item.
+
+Lists can't be nested. Blank lines are currently not supported within
+lists.
+
+Additional whitespace between the initial '#' and the comment text is
+permitted.
+
+*foo* and _foo_ are for strong and emphasis styles respectively (they
+do not work over multiple lines). @foo is used to reference a name in
+the schema.
+
+Example:
+
+##
+# = Section
+# == Subsection
+#
+# Some text foo with *strong* and _emphasis_
+# 1. with a list
+# 2. like that
+#
+# And some code:
+# | $ echo foo
+# | -> do this
+# | <- get that
+#
+##
+
+
+==== Expression documentation ====
+
+Each expression that isn't an include directive must be preceded by a
+documentation block. Such blocks are called expression documentation
+blocks.
+
+The documentation block consists of a first line naming the
+expression, an optional overview, a description of each argument (for
+commands and events) or member (for structs, unions and alternates),
+and optional tagged sections.
+
+FIXME: the parser accepts these things in almost any order.
+
+Optional arguments / members are tagged with the phrase '#optional',
+often with their default value; and extensions added after the
+expression was first released are also given a '(since x.y.z)'
+comment.
+
+A tagged section starts with one of the following words:
+"Note:"/"Notes:", "Since:", "Example"/"Examples", "Returns:", "TODO:".
+The section ends with the start of a new section.
+
+A 'Since: x.y.z' tagged section lists the release that introduced the
+expression.
+
+For example:
+
+##
+# @BlockStats:
+#
+# Statistics of a virtual block device or a block backing device.
+#
+# @device: #optional If the stats are for a virtual block device, the name
+# corresponding to the virtual block device.
+#
+# @node-name: #optional The node name of the device. (since 2.3)
+#
+# ... more members ...
+#
+# Since: 0.14.0
+##
+{ 'struct': 'BlockStats',
+ 'data': {'*device': 'str', '*node-name': 'str',
+ ... more members ... } }
+
+##
+# @query-blockstats:
+#
+# Query the @BlockStats for all virtual block devices.
+#
+# @query-nodes: #optional If true, the command will query all the
+# block nodes ... explain, explain ... (since 2.3)
+#
+# Returns: A list of @BlockStats for each virtual block devices.
+#
+# Since: 0.14.0
+#
+# Example:
+#
+# -> { "execute": "query-blockstats" }
+# <- {
+# ... lots of output ...
+# }
+#
+##
+{ 'command': 'query-blockstats',
+ 'data': { '*query-nodes': 'bool' },
+ 'returns': ['BlockStats'] }
+
+==== Free-form documentation ====
+
+A documentation block that isn't an expression documentation block is
+a free-form documentation block. These may be used to provide
+additional text and structuring content.
+
+
+=== Schema overview ===
The schema sets up a series of types, as well as commands and events
that will use those types. Forward references are allowed: the parser

- QMP Supported Commands
- ----------------------
-
-This document describes all commands currently supported by QMP.
-
-Most of the time their usage is exactly the same as in the user Monitor, this
-means that any other document which also describe commands (the manpage,
-QEMU's manual, etc) can and should be consulted.
-
-QMP has two types of commands: regular and query commands. Regular commands
-usually change the Virtual Machine's state someway, while query commands just
-return information. The sections below are divided accordingly.
-
-It's important to observe that all communication examples are formatted in
-a reader-friendly way, so that they're easier to understand. However, in real
-protocol usage, they're emitted as a single line.
-
-Also, the following notation is used to denote data flow:
-
--> data issued by the Client
-<- Server data response
-
-Please, refer to the QMP specification (docs/qmp-spec.txt) for detailed
-information on the Server command and response formats.
-
-NOTE: This document is temporary and will be replaced soon.
-
-1. Stability Considerations
-===========================
-
-The current QMP command set (described in this file) may be useful for a
-number of use cases, however it's limited and several commands have bad
-defined semantics, specially with regard to command completion.
-
-These problems are going to be solved incrementally in the next QEMU releases
-and we're going to establish a deprecation policy for badly defined commands.
-
-If you're planning to adopt QMP, please observe the following:
-
- 1. The deprecation policy will take effect and be documented soon, please
- check the documentation of each used command as soon as a new release of
- QEMU is available
-
- 2. DO NOT rely on anything which is not explicit documented
-
- 3. Errors, in special, are not documented. Applications should NOT check
- for specific errors classes or data (it's strongly recommended to only
- check for the "error" key)
-
-2. Regular Commands
-===================
-
-Server's responses in the examples below are always a success response, please
-refer to the QMP specification for more details on error responses.

- up on encountering NUL characters, after the ring buffer
- lost data, and when reading stops because the size limit
- is reached.

-transaction
------------
-
-Atomically operate on one or more block devices. Operations that are
-currently supported:
-
- - drive-backup
- - blockdev-backup
- - blockdev-snapshot-sync
- - blockdev-snapshot-internal-sync
- - abort
- - block-dirty-bitmap-add
- - block-dirty-bitmap-clear
-
-Refer to the qemu/qapi-schema.json file for minimum required QEMU
-versions for these operations. A list of dictionaries is accepted,
-that contains the actions to be performed. If there is any failure
-performing any of the operations, all operations for the group are
-abandoned.
-
-For external snapshots, the dictionary contains the device, the file to use for
-the new snapshot, and the format. The default format, if not specified, is
-qcow2.
-
-Each new snapshot defaults to being created by QEMU (wiping any
-contents if the file already exists), but it is also possible to reuse
-an externally-created file. In the latter case, you should ensure that
-the new image file has the same contents as the current one; QEMU cannot
-perform any meaningful check. Typically this is achieved by using the
-current image file as the backing file for the new image.
-
-On failure, the original disks pre-snapshot attempt will be used.
-
-For internal snapshots, the dictionary contains the device and the snapshot's
-name. If an internal snapshot matching name already exists, the request will
-be rejected. Only some image formats support it, for example, qcow2, rbd,
-and sheepdog.
-
-On failure, qemu will try delete the newly created internal snapshot in the
-transaction. When an I/O error occurs during deletion, the user needs to fix
-it later with qemu-img or other command.
-
-Arguments:
-
-actions array:

-------------------
-
-Opens a block device's tray. If there is a block driver state tree inserted as a

-to the block device, so closing the tray will make it accessible again).
-
-If the tray was already open before, this will be a no-op.
-
-Once the tray opens, a DEVICE_TRAY_MOVED event is emitted. There are cases in
-which no such event will be generated, these include:
-- if the guest has locked the tray, @force is false and the guest does not
- respond to the eject request
-- if the BlockBackend denoted by @device does not have a guest device attached
- to it
-- if the guest device does not have an actual tray and is empty, for instance
- for floppy disk drives
-
-Arguments:
-
-- "device": block device name (deprecated, use @id instead)
- (json-string, optional)
-- "id": the name or QOM path of the guest device (json-string, optional)

- it has locked the tray (and the tray will not be opened immediately);
- if true, the tray will be opened regardless of whether it is locked
- (json-bool, optional)
-
-Example:
-
--> { "execute": "blockdev-open-tray",
- "arguments": { "id": "ide0-1-0" } }
-
-<- { "timestamp": { "seconds": 1418751016,

- "tray-open": true } }
-
-<- { "return": {} }
-
-blockdev-close-tray
--------------------
-
-Closes a block device's tray. If there is a block driver state tree associated

-
-x-blockdev-change
------------------
-
-Dynamically reconfigure the block driver state graph. It can be used

-trace-event-set-state
----------------------
-
-Set the state of events.
-
-Arguments:
-
-- "name": Event name pattern (json-string).
-- "enable": Whether to enable or disable the event (json-bool).
-- "ignore-unavailable": Whether to ignore errors for events that cannot be
- changed (json-bool, optional).
-- "vcpu": The vCPU to act upon, all vCPUs by default (json-int, optional).
-
-An event's state is modified if:
-- its name matches the "name" pattern, and
-- if "vcpu" is given, the event has the "vcpu" property.
-
-Therefore, if "vcpu" is given, the operation will only match per-vCPU events,
-setting their state on the specified vCPU. Special case: if "name" is an exact
-match, "vcpu" is given and the event does not have the "vcpu" property, an error
-is returned.
