5 # This document describes all commands currently supported by QMP.
7 # Most of the time their usage is exactly the same as in the user Monitor, this
8 # means that any other document which also describe commands (the manpage,
9 # QEMU's manual, etc) can and should be consulted.
11 # QMP has two types of commands: regular and query commands. Regular commands
12 # usually change the Virtual Machine's state someway, while query commands just
13 # return information. The sections below are divided accordingly.
15 # It's important to observe that all communication examples are formatted in
16 # a reader-friendly way, so that they're easier to understand. However, in real
17 # protocol usage, they're emitted as a single line.
19 # Also, the following notation is used to denote data flow:
23 # | -> data issued by the Client
24 # | <- Server data response
26 # Please, refer to the QMP specification (docs/interop/qmp-spec.txt) for
27 # detailed information on the Server command and response formats.
29 # = Stability Considerations
31 # The current QMP command set (described in this file) may be useful for a
32 # number of use cases, however it's limited and several commands have bad
33 # defined semantics, specially with regard to command completion.
35 # These problems are going to be solved incrementally in the next QEMU releases
36 # and we're going to establish a deprecation policy for badly defined commands.
38 # If you're planning to adopt QMP, please observe the following:
40 # 1. The deprecation policy will take effect and be documented soon, please
41 # check the documentation of each used command as soon as a new release of
44 # 2. DO NOT rely on anything which is not explicit documented
46 # 3. Errors, in special, are not documented. Applications should NOT check
47 # for specific errors classes or data (it's strongly recommended to only
48 # check for the "error" key)
52 { 'pragma': { 'doc-required': true } }
54 # Whitelists to permit QAPI rule violations; think twice before you
57 # Commands allowed to return a non-dictionary:

59 'human-monitor-command',
61 'query-migrate-cache-size',
65 'name-case-whitelist': [
66 'ACPISlotType', # DIMM, visible through query-acpi-ospm-status
67 'CpuInfoMIPS', # PC, visible through query-cpu
68 'CpuInfoTricore', # PC, visible through query-cpu
69 'QapiErrorClass', # all members, visible through errors
70 'UuidInfo', # UUID, visible through query-uuid
71 'X86CPURegister32', # all members, visible indirectly through qom-get
72 'q_obj_CpuInfo-base' # CPU, visible through query-cpu
75 # Documentation generated with qapi-gen.py is in source order, with
76 # included sub-schemas inserted at the first include directive
77 # (subsequent include directives have no effect). To get a sane and
78 # stable order, it's best to include each sub-schema just once, or
79 # include it first right here.
