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
52# the object model.
53#
54# @path: the path within the object model.  See @qom-get for a
55#     description of this parameter.

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#

108#
109# 1. Use absolute path

643#     Some backend stores specified by @mem-path require an alignment
644#     different than the default one used by QEMU, e.g. the device DAX
645#     /dev/dax0.0 requires 2M alignment rather than 4K. In such cases,
646#     users can specify the required alignment via this option.  0
647#     selects a default alignment (currently the page size).
648#     (default: 0)
649#
650# @offset: the offset into the target file that the region starts at.
651#     You can use this option to back multiple regions with a single
652#     file. Must be a multiple of the page size.
653#     (default: 0) (since 8.1)
654#
655# @discard-data: if true, the file contents can be destroyed when QEMU
656#     exits, to avoid unnecessarily flushing data to the backing file.
657#     Note that @discard-data is only an optimization, and QEMU might
658#     not discard file contents if it aborts unexpectedly or is
659#     terminated using SIGKILL. (default: false)

664# @pmem: specifies whether the backing file specified by @mem-path is
665#     in host persistent memory that can be accessed using the SNIA
666#     NVM programming model (e.g. Intel NVDIMM).
667#
668# @readonly: if true, the backing file is opened read-only; if false,
669#     it is opened read-write.  (default: false)
670#
671# @rom: whether to create Read Only Memory (ROM) that cannot be modified
672#       by the VM.  Any write attempts to such ROM will be denied.  Most
673#       use cases want writable RAM instead of ROM.  However, selected use
674#       cases, like R/O NVDIMMs, can benefit from ROM.  If set to 'on',
675#       create ROM; if set to 'off', create writable RAM;  if set to
676#       'auto', the value of the @readonly property is used.  This
677#       property is primarily helpful when we want to have proper RAM in
678#       configurations that would traditionally create ROM before this
679#       property was introduced: VM templating, where we want to open a
680#       file readonly (@readonly set to true) and mark the memory to be
681#       private for QEMU (@share set to false).  For this use case, we need
682#       writable RAM instead of ROM, and want to set this property to 'off'.
