17# @ObjectPropertyInfo:
18#
19# @name: the name of the property
20#
21# @type: the type of the property.  This will typically come in one of
22#     four forms:
23#
24#     1) A primitive type such as 'u8', 'u16', 'bool', 'str', or
25#        'double'.  These types are mapped to the appropriate JSON
26#        type.
27#
28#     2) A child type in the form 'child<subtype>' where subtype is a
29#        qdev device type name.  Child properties create the
30#        composition tree.
31#
32#     3) A link type in the form 'link<subtype>' where subtype is a
33#        qdev device type name.  Link properties form the device model
34#        graph.
35#
36# @description: if specified, the description of the property.
37#
38# @default-value: the default value, if any (since 5.0)
39#
40# Since: 1.2

49# @qom-list:
50#
51# This command will list any properties of a object given a path in

53#
54# @path: the path within the object model.  See @qom-get for a

77# @qom-get:
78#
79# This command will get a property from a object model path and return
80# the value.
81#
82# @path: The path within the object model.  There are two forms of
83#     supported paths--absolute and partial paths.
84#
85#     Absolute paths are derived from the root object and can follow
86#     child<> or link<> properties.  Since they can follow link<>
87#     properties, they can be arbitrarily long.  Absolute paths look
88#     like absolute filenames and are prefixed  with a leading slash.
89#
90#     Partial paths look like relative filenames.  They do not begin
91#     with a prefix.  The matching rules for partial paths are subtle
92#     but designed to make specifying objects easy.  At each level of
93#     the composition tree, the partial path is matched as an absolute
94#     path.  The first match is not returned.  At least two matches
95#     are searched for.  A successful result is only returned if only
96#     one match is found.  If more than one match is found, a flag is
97#     return to indicate that the match was ambiguous.
98#
99# @property: The property name to read
100#
101# Returns: The property value.  The type depends on the property type.
102#     child<> and link<> properties are returned as #str pathnames.
103#     All integer property types (u8, u16, etc) are returned as #int.
104#
105# Since: 1.2
106#
107# Examples:
108#
109#     1. Use absolute path

646#     different than the default one used by QEMU, e.g. the device DAX

648#     users can specify the required alignment via this option.  0
649#     selects a default alignment (currently the page size).
650#     (default: 0)
651#
652# @offset: the offset into the target file that the region starts at.
653#     You can use this option to back multiple regions with a single
654#     file.  Must be a multiple of the page size.
655#     (default: 0) (since 8.1)
656#
657# @discard-data: if true, the file contents can be destroyed when QEMU
658#     exits, to avoid unnecessarily flushing data to the backing file.
659#     Note that @discard-data is only an optimization, and QEMU might
660#     not discard file contents if it aborts unexpectedly or is

667#     in host persistent memory that can be accessed using the SNIA
668#     NVM programming model (e.g. Intel NVDIMM).

670# @readonly: if true, the backing file is opened read-only; if false,

673# @rom: whether to create Read Only Memory (ROM) that cannot be
674#     modified by the VM.  Any write attempts to such ROM will be
675#     denied.  Most use cases want writable RAM instead of ROM.
676#     However, selected use cases, like R/O NVDIMMs, can benefit from
677#     ROM.  If set to 'on', create ROM; if set to 'off', create
678#     writable RAM; if set to 'auto', the value of the @readonly
679#     property is used.  This property is primarily helpful when we
680#     want to have proper RAM in configurations that would
681#     traditionally create ROM before this property was introduced: VM
682#     templating, where we want to open a file readonly (@readonly set
683#     to true) and mark the memory to be private for QEMU (@share set
684#     to false).  For this use case, we need writable RAM instead of
685#     ROM, and want to set this property to 'off'.  (default: auto,
