15# Arguments:
16#
17# @enable:   An optional list of QMPCapability values to enable.  The
18#            client must not enable any capability that is not
19#            mentioned in the QMP greeting message.  If the field is not
20#            provided, it means no QMP capabilities will be enabled.
21#            (since 2.12)

27# <- { "return": {} }

29# Notes: This command is valid exactly when first connecting: it must be
30# issued before any other command will be accepted, and will fail once the
31# monitor is accepting other commands. (see qemu docs/interop/qmp-spec.txt)
32#
33# The QMP client needs to explicitly enable QMP capabilities, otherwise
34# all the QMP capabilities will be turned off by default.

1745# Dump guest's memory to vmcore. It is a synchronous operation that can take
1746# very long depending on the amount of guest memory.
1747#
1748# @paging: if true, do paging to get guest's memory mapping. This allows
1749#          using gdb to process the core file.
1750#
1751#          IMPORTANT: this option can make QEMU allocate several gigabytes
1752#                     of RAM. This can happen for a large guest, or a
1753#                     malicious guest pretending to be large.
1754#
1755#          Also, paging=true has the following limitations:
1756#
1757#             1. The guest may be in a catastrophic state or can have corrupted
1758#                memory, which cannot be trusted
1759#             2. The guest can be in real-mode even if paging is enabled. For
1760#                example, the guest uses ACPI to sleep, and ACPI sleep state
1761#                goes in real-mode
1762#             3. Currently only supported on i386 and x86_64.
1763#
1764# @protocol: the filename or file descriptor of the vmcore. The supported
1765#            protocols are:

1769#            2. fd: the protocol starts with "fd:", and the following string
1770#               is the fd's name.
1771#
1772# @detach: if true, QMP will return immediately rather than
1773#          waiting for the dump to finish. The user can track progress
1774#          using "query-dump". (since 2.6).

2103# that an architecture might require should be hidden behind the name.

2105#
2106# @name: the name of the CPU definition the model is based on

2116# @CpuModelExpansionType:

2118# An enumeration of CPU model expansion types.
2119#
2120# @static: Expand to a static CPU model, a combination of a static base
2121#          model name and property delta changes. As the static base model will
2122#          never change, the expanded CPU model will be the same, independent of
2123#          QEMU version, machine type, machine options, and accelerator options.
2124#          Therefore, the resulting model can be used by tooling without having
2125#          to specify a compatibility machine - e.g. when displaying the "host"
2126#          model. The @static CPU models are migration-safe.
2127
2128# @full: Expand all properties. The produced model is not guaranteed to be
2129#        migration-safe, but allows tooling to get an insight and work with
2130#        model details.
2131#
2132# Note: When a non-migration-safe CPU model is expanded in static mode, some
2133# features enabled by the CPU model may be omitted, because they can't be
2134# implemented by a static CPU model definition (e.g. cache info passthrough and
2135# PMU passthrough in x86). If you need an accurate representation of the
2136# features enabled by a non-migration-safe CPU model, use @full. If you need a
2137# static representation that will keep ABI compatibility even when changing QEMU
2138# version or machine-type, use @static (but keep in mind that some features may
2139# be omitted).
