##
# @ObjectPropertyInfo:
#
# @name: the name of the property
#
# @type: the type of the property.  This will typically come in one of
#     four forms:
#
#     1) A primitive type such as 'u8', 'u16', 'bool', 'str', or
#        'double'.  These types are mapped to the appropriate JSON
#        type.
#
#     2) A child type in the form 'child<subtype>' where subtype is a
#        qdev device type name.  Child properties create the
#        composition tree.
#
#     3) A link type in the form 'link<subtype>' where subtype is a
#        qdev device type name.  Link properties form the device model
#        graph.
#
# @description: if specified, the description of the property.
#
# @default-value: the default value, if any (since 5.0)
#
# Since: 1.2

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

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

#     of the object.

##
# @qom-get:
#
# This command will get a property from a object model path and return
# the value.
#
# @path: The path within the object model.  There are two forms of
#     supported paths--absolute and partial paths.
#
#     Absolute paths are derived from the root object and can follow
#     child<> or link<> properties.  Since they can follow link<>
#     properties, they can be arbitrarily long.  Absolute paths look
#     like absolute filenames and are prefixed  with a leading slash.
#
#     Partial paths look like relative filenames.  They do not begin
#     with a prefix.  The matching rules for partial paths are subtle
#     but designed to make specifying objects easy.  At each level of
#     the composition tree, the partial path is matched as an absolute
#     path.  The first match is not returned.  At least two matches
#     are searched for.  A successful result is only returned if only
#     one match is found.  If more than one match is found, a flag is
#     return to indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value.  The type depends on the property type.
#     child<> and link<> properties are returned as #str pathnames.
#     All integer property types (u8, u16, etc) are returned as #int.
#
# Since: 1.2
#
# Examples:
#
#     1. Use absolute path
#
#     -> { "execute": "qom-get",
#          "arguments": { "path": "/machine/unattached/device[0]",
#                         "property": "hotplugged" } }

#                         "property": "type" } }

# @MemoryBackendFileProperties:
#
# Properties for memory-backend-file objects.
#
# @align: the base address alignment when QEMU mmap(2)s @mem-path.
#     Some backend stores specified by @mem-path require an alignment
#     different than the default one used by QEMU, e.g. the device DAX
#     /dev/dax0.0 requires 2M alignment rather than 4K. In such cases,
#     users can specify the required alignment via this option.  0
#     selects a default alignment (currently the page size).
#     (default: 0)
#
# @offset: the offset into the target file that the region starts at.
#     You can use this option to back multiple regions with a single
#     file.  Must be a multiple of the page size.
#     (default: 0) (since 8.1)
#
# @discard-data: if true, the file contents can be destroyed when QEMU
#     exits, to avoid unnecessarily flushing data to the backing file.
#     Note that @discard-data is only an optimization, and QEMU might
#     not discard file contents if it aborts unexpectedly or is
#     terminated using SIGKILL.  (default: false)
#
# @mem-path: the path to either a shared memory or huge page
#     filesystem mount
#
# @pmem: specifies whether the backing file specified by @mem-path is
#     in host persistent memory that can be accessed using the SNIA
#     NVM programming model (e.g. Intel NVDIMM).
#
# @readonly: if true, the backing file is opened read-only; if false,
#     it is opened read-write.  (default: false)
#
# @rom: whether to create Read Only Memory (ROM) that cannot be
#     modified by the VM.  Any write attempts to such ROM will be
#     denied.  Most use cases want writable RAM instead of ROM.
#     However, selected use cases, like R/O NVDIMMs, can benefit from
#     ROM.  If set to 'on', create ROM; if set to 'off', create
#     writable RAM; if set to 'auto', the value of the @readonly
#     property is used.  This property is primarily helpful when we
#     want to have proper RAM in configurations that would
#     traditionally create ROM before this property was introduced: VM
#     templating, where we want to open a file readonly (@readonly set
#     to true) and mark the memory to be private for QEMU (@share set
#     to false).  For this use case, we need writable RAM instead of
#     ROM, and want to set this property to 'off'.  (default: auto,
#     since 8.2)

# More usage information is also available in the QEMU source tree
# under docs/amd-memory-encryption.

#     structure for the SNP_LAUNCH_FINISH command defined in the
#     SEV-SNP firmware ABI (default: all-zero)
#
# @id-auth: 4096-byte, base64-encoded blob to provide the 'ID
#     Authentication Information Structure' for the SNP_LAUNCH_FINISH
#     command defined in the SEV-SNP firmware ABI (default: all-zero)
#
# @author-key-enabled: true if 'id-auth' blob contains the 'AUTHOR_KEY'
#     field defined SEV-SNP firmware ABI (default: false)

# @host-data: 32-byte, base64-encoded, user-defined blob to provide to

#     Endorsement Key) when requesting attestation reports from
#     firmware. Set this to true to disable the use of VCEK.
