'qmp_cpu' was implemented in commit 755f196898 ("qapi: Convert the cpu
command") as a functional no-op, a QMP call that does nothing and
return success. The idea, apparently, was to provide a counterpart
for the HMP 'hmp_cpu' command, introduced in the same commit.
After 6 years of its creation, qmp_cpu remains a functional no-op
that does nothing, having no value for any caller/user. A proposal
was sent to implement qmp_cpu like hmp_cpu works, but it was denied
[1]. The reason is that QMP must be as stateless as possible and a
function that changes its state (the current CPU monitor in the case
of qmp_cpu) goes against it. Any QMP command that needs a specific
monitor CPU setup must provide it in its arguments, instead of relying
in the current QMP monitor state.
After discussions that happened in [2] it was decided that a command
that does nothing since its birth, no one uses for anything and will
not be implemented, should be deprecated and erased. Given that we will
*not* provide any replacement for qmp_cpu and we believe that there
is no user relying on it, there is no point in adding a deprecation
delay for it.
So, this patch nukes qmp_cpu from QEMU code, removing both its blank
implementation in qmp.c and its doc in qapi-schema.json.

# = Introduction
|
|
#
|
|
# This document describes all commands currently supported by QMP.
|
|
#
|
|
# Most of the time their usage is exactly the same as in the user Monitor, this
|
|
# means that any other document which also describe commands (the manpage,
|
|
# QEMU's manual, etc) can and should be consulted.
|
|
#
|
|
# QMP has two types of commands: regular and query commands. Regular commands
|
|
# usually change the Virtual Machine's state someway, while query commands just
|
|
# return information. The sections below are divided accordingly.
|
|
#
|
|
# It's important to observe that all communication examples are formatted in
|
|
# a reader-friendly way, so that they're easier to understand. However, in real
|
|
# protocol usage, they're emitted as a single line.
|
|
#
|
|
# Also, the following notation is used to denote data flow:
|
|
#
|
|
# Example:
|
|
#
|
|
# | -> data issued by the Client
|
|
# | <- Server data response
|
|
#
|
|
# Please, refer to the QMP specification (docs/interop/qmp-spec.txt) for
|
|
# detailed information on the Server command and response formats.
|
|
#
|
|
# = Stability Considerations
|
|
#
|
|
# The current QMP command set (described in this file) may be useful for a
|
|
# number of use cases, however it's limited and several commands have bad
|
|
# defined semantics, specially with regard to command completion.
|
|
#
|
|
# These problems are going to be solved incrementally in the next QEMU releases
|
|
# and we're going to establish a deprecation policy for badly defined commands.
|
|
#
|
|
# If you're planning to adopt QMP, please observe the following:
|
|
#
|
|
# 1. The deprecation policy will take effect and be documented soon, please
|
|
# check the documentation of each used command as soon as a new release of
|
|
# QEMU is available
|
|
#
|
|
# 2. DO NOT rely on anything which is not explicit documented
|
|
#
|
|
# 3. Errors, in special, are not documented. Applications should NOT check
|
|
# for specific errors classes or data (it's strongly recommended to only
|
|
# check for the "error" key)
|
|

# @path: The path within the object model. There are two forms of supported

|
|
#
|
|
# Absolute paths are derived from the root object and can follow child<>
|

|
# 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

|

# Dump guest's memory to vmcore. It is a synchronous operation that can take

# very long depending on the amount of guest memory.
|
|
#
|
|
# @paging: if true, do paging to get guest's memory mapping. This allows

|
# IMPORTANT: this option can make QEMU allocate several gigabytes
|
|
# of RAM. This can happen for a large guest, or a
|
|
# malicious guest pretending to be large.
|
|
#
|
|
# Also, paging=true has the following limitations:
|
|
#
|
|
# 1. The guest may be in a catastrophic state or can have corrupted
|
|
# memory, which cannot be trusted
|
|
# 2. The guest can be in real-mode even if paging is enabled. For
|
|
# example, the guest uses ACPI to sleep, and ACPI sleep state

# using "query-dump". (since 2.6).
