# = 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)
#

qapi: New QMP command query-qmp-schema for QMP introspection qapi/introspect.json defines the introspection schema. It's designed for QMP introspection, but should do for similar uses, such as QGA. The introspection schema does not reflect all the rules and restrictions that apply to QAPI schemata. A valid QAPI schema has an introspection value conforming to the introspection schema, but the converse is not true. Introspection lowers away a number of schema details, and makes implicit things explicit: * The built-in types are declared with their JSON type. All integer types are mapped to 'int', because how many bits we use internally is an implementation detail. It could be pressed into external interface service as very approximate range information, but that's a bad idea. If we need range information, we better do it properly. * Implicit type definitions are made explicit, and given auto-generated names: - Array types, named by appending "List" to the name of their element type, like in generated C. - The enumeration types implicitly defined by simple union types, named by appending "Kind" to the name of their simple union type, like in generated C. - Types that don't occur in generated C. Their names start with ':' so they don't clash with the user's names. * All type references are by name. * The struct and union types are generalized into an object type. * Base types are flattened. * Commands take a single argument and return a single result. Dictionary argument or list result is an implicit type definition. The empty object type is used when a command takes no arguments or produces no results. The argument is always of object type, but the introspection schema doesn't reflect that. The 'gen': false directive is omitted as implementation detail. The 'success-response' directive is omitted as well for now, even though it's not an implementation detail, because it's not used by QMP. * Events carry a single data value. Implicit type definition and empty object type use, just like for commands. The value is of object type, but the introspection schema doesn't reflect that. * Types not used by commands or events are omitted. Indirect use counts as use. * Optional members have a default, which can only be null right now Instead of a mandatory "optional" flag, we have an optional default. No default means mandatory, default null means optional without default value. Non-null is available for optional with default (possible future extension). * Clients should *not* look up types by name, because type names are not ABI. Look up the command or event you're interested in, then follow the references. TODO Should we hide the type names to eliminate the temptation? New generator scripts/qapi-introspect.py computes an introspection value for its input, and generates a C variable holding it. It can generate awfully long lines. Marked TODO. A new test-qmp-input-visitor test case feeds its result for both tests/qapi-schema/qapi-schema-test.json and qapi-schema.json to a QmpInputVisitor to verify it actually conforms to the schema. New QMP command query-qmp-schema takes its return value from that variable. Its reply is some 85KiBytes for me right now. If this turns out to be too much, we have a couple of options: * We can use shorter names in the JSON. Not the QMP style. * Optionally return the sub-schema for commands and events given as arguments. Right now qmp_query_schema() sends the string literal computed by qmp-introspect.py. To compute sub-schema at run time, we'd have to duplicate parts of qapi-introspect.py in C. Unattractive. * Let clients cache the output of query-qmp-schema. It changes only on QEMU upgrades, i.e. rarely. Provide a command query-qmp-schema-hash. Clients can have a cache indexed by hash, and re-query the schema only when they don't have it cached. Even simpler: put the hash in the QMP greeting. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

# Returns: If successful, nothing
#
# Notes: This command will succeed if the guest is currently running. It

# that rely on long term stability guarantees should NOT
# use this command.
#
# Known limitations:
#
# * This command is stateless, this means that commands that depend

# 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

#
# 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

##
# @change:
#
# This command is multiple commands multiplexed together.
#
# @device: This is normally the name of a block device but it may also be 'vnc'.
# when it's 'vnc', then sub command depends on @target
#
# @target: If @device is a block device, then this is the new filename.
# If @device is 'vnc', then if the value 'password' selects the vnc
# change password command. Otherwise, this specifies a new server URI
# address to listen to for VNC connections.
#
# @arg: If @device is a block device, then this is an optional format to open
# the device with.
# If @device is 'vnc' and @target is 'password', this is the new VNC
# password to set. See change-vnc-password for additional notes.
#
# Returns: Nothing on success.
# If @device is not a valid block device, DeviceNotFound

# @dump-guest-memory:
#
# 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
# using gdb to process the core file.
#
# 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
# goes in real-mode
# 3. Currently only supported on i386 and x86_64.
#
# @protocol: the filename or file descriptor of the vmcore. The supported
# protocols are:
#
# 1. file: the protocol starts with "file:", and the following
# string is the file's path.
# 2. fd: the protocol starts with "fd:", and the following string
# is the fd's name.
#
# @detach: if true, QMP will return immediately rather than
# waiting for the dump to finish. The user can track progress
# using "query-dump". (since 2.6).
#
# @begin: if specified, the starting physical address.
#
# @length: if specified, the memory size, in bytes. If you don't
# want to dump all guest's memory, please specify the start @begin
# and @length
#
# @format: if specified, the format of guest memory dump. But non-elf
# format is conflict with paging and filter, ie. @paging, @begin and
# @length is not allowed to be specified with non-elf @format at the
# same time (since 2.0)

net: add support of mac-programming over macvtap in QEMU side Currently macvtap based macvlan device is working in promiscuous mode, we want to implement mac-programming over macvtap through Libvirt for better performance. Design: QEMU notifies Libvirt when rx-filter config is changed in guest, then Libvirt query the rx-filter information by a monitor command, and sync the change to macvtap device. Related rx-filter config of the nic contains main mac, rx-mode items and vlan table. This patch adds a QMP event to notify management of rx-filter change, and adds a monitor command for management to query rx-filter information. Test: If we repeatedly add/remove vlan, and change macaddr of vlan interfaces in guest by a loop script. Result: The events will flood the QMP client(management), management takes too much resource to process the events. Event_throttle API (set rate to 1 ms) can avoid the events to flood QMP client, but it could cause an unexpected delay (~1ms), guests guests normally expect rx-filter updates immediately. So we use a flag for each nic to avoid events flooding, the event is emitted once until the query command is executed. The flag implementation could not introduce unexpected delay. There maybe exist an uncontrollable delay if we let Libvirt do the real change, guests normally expect rx-filter updates immediately. But it's another separate issue, we can investigate it when the work in Libvirt side is done. Michael S. Tsirkin: tweaked to enable events on start Michael S. Tsirkin: fixed not to crash when no id Michael S. Tsirkin: fold in patch: "additional fixes for mac-programming feature" Amos Kong: always notify QMP client if mactable is changed Amos Kong: return NULL list if no net client supports rx-filter query Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Amos Kong <akong@redhat.com> Signed-off-by: Michael S.

qapi: Lazy creation of array types Commit ac88219a had several TODO markers about whether we needed to automatically create the corresponding array type alongside any other type. It turns out that most of the time, we don't! There are a few exceptions: 1) We have a few situations where we use an array type in internal code but do not expose that type through QMP; fix it by declaring a dummy type that forces the generator to see that we want to use the array type. 2) The builtin arrays (such as intList for QAPI ['int']) must always be generated, because of the way our QAPI_TYPES_BUILTIN compile guard works: we have situations (at the very least tests/test-qmp-output-visitor.c) that include both top-level "qapi-types.h" (via "error.h") and a secondary "test-qapi-types.h". If we were to only emit the builtin types when used locally, then the first .h file would not include all types, but the second .h does not declare anything at all because the first .h set QAPI_TYPES_BUILTIN, and we would end up with compilation error due to things like unknown type 'int8List'. Actually, we may need to revisit how we do type guards, and change from a single QAPI_TYPES_BUILTIN over to a different usage pattern that does one #ifdef per qapi type - right now, the only types that are declared multiple times between two qapi .json files for inclusion by a single .c file happen to be the builtin arrays. But now that we have QAPI 'include' statements, it is logical to assume that we will soon reach a point where we want to reuse non-builtin types (yes, I'm thinking about what it will take to add introspection to QGA, where we will want to reuse the SchemaInfo type and friends). One #ifdef per type will help ensure that generating the same qapi type into more than one qapi-types.h won't cause collisions when both are included in the same .c file; but we also have to solve how to avoid creating duplicate qapi-types.c entry points. So that is a problem left for another day. Generated code for qapi-types and qapi-visit is drastically reduced; less than a third of the arrays that were blindly created were actually needed (a quick grep shows we dropped from 219 to 69 *List types), and the .o files lost more than 30% of their bulk. [For best results, diff the generated files with 'git diff --patience --no-index pre post'.] Interestingly, the introspection output is unchanged - this is because we already cull all types that are not indirectly reachable from a command or event, so introspection was already using only a subset of array types. The subset of types introspected is now a much larger percentage of the overall set of array types emitted in qapi-types.h (since the larger set shrunk), but still not 100% (evidence that the array types emitted for our new Dummy structs, and the new struct itself, don't affect QMP).

However cpu index is internal concept and QEMU users have to guess /reimplement qemu's logic/ to map it to a concrete cpu socket/core/thread to make sane CPUs placement across numa nodes. This patch allows to map cpu objects to numa nodes using the same properties as used for cpus with -device/device_add (socket-id/core-id/thread-id/node-id). At present valid properties/values to address CPUs could be fetched using hotpluggable-cpus monitor/qmp command, it will require user to start qemu twice when creating domain to fetch possible CPUs for a machine type/-smp layout first and then the second time with numa explicit mapping for actual usage.

arm: qmp: add query-gic-capabilities interface This patch add "query-gic-capabilities" but does not implement it. The command is ARM-only. The command will return a list of GICCapability structs that describes all GIC versions that current QEMU and system support. Libvirt is possibly the first consumer of this new command. Before this patch, a libvirt user can successfully configure all kinds of GIC devices for ARM guests, no matter whether current QEMU/kernel supports them. If the specified GIC version/type is not supported, the user will get an ambiguous "QEMU boot failure" error when trying to start the VM. This is not user-friendly. With this patch, libvirt should be able to query which type (and which version) of GIC device is supported. Using this information, libvirt can warn the user during configuration of guests when specified GIC device type is not supported. Or better, we can just list those versions that we support, and filter out the unsupported ones. For example, if we got the query result: {"return": [{"emulated": false, "version": 3, "kernel": true}, {"emulated": true, "version": 2, "kernel": false}]} then it means that we support emulated GIC version 2 using: qemu-system-aarch64 -M virt,accel=tcg,gic-version=2 ... or KVM-accelerated GIC version 3 using: qemu-system-aarch64 -M virt,accel=kvm,gic-version=3 ... If we specify other explicit GIC versions rather than the above, QEMU will not be able to boot. The community is working on a more generic way to query these kinds of information about valid values of machine properties. However, due to the importance of supporting this specific use case, weecided to first implement this ad-hoc one; then when the generic method is ready, we can move on to that one smoothly.
