CXL uses PCI AER Internal errors to signal to the host that an error has
occurred. The host can then read more detailed status from the CXL RAS
capability.
For uncorrectable errors: support multiple injection in one operation
as this is needed to reliably test multiple header logging support in an
OS. The equivalent feature doesn't exist for correctable errors, so only
one error need be injected at a time.
Note:
- Header content needs to be manually specified in a fashion that
matches the specification for what can be in the header for each
error type.

# = 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)
|
|
#
|

|
|
|
|
# Documentation generated with qapi-gen.py is in source order, with
|
|
# included sub-schemas inserted at the first include directive
|
|
# (subsequent include directives have no effect). To get a sane and
|
|
# stable order, it's best to include each sub-schema just once, or
|
|
# include it first right here.
