The only remaining function of qmp-commands.hx is to let us generate
qmp-commands.txt from it. Replace qmp-commands.hx by qmp-commands.txt.
We intend to move the documentation into the QAPI schema and generate
qapi-commands.txt from it, but not right now.

Let's provide a standardized interface to baseline two CPU models, to
create a third, compatible one. This is especially helpful when two
CPU models are not identical, but a CPU model is required that is
guaranteed to run under both configurations, where the original models run.
"query-cpu-model-baseline" takes two CPU models and returns a third,
compatible model. The result will always be a static CPU model.

Let's provide a standardized interface to compare two CPU models.
"query-cpu-model-compare" takes two models and returns how they compare
in a specific configuration.
The result will give guarantees about runnability. E.g. if a CPU model A
is a subset of CPU model B, model A is guaranteed to run in configurations
where model B runs, but not the other way around (might or might not run).
Usually, CPU features or CPU generations are used to calculate the result.
If a model is not guaranteed to run in a certain environment (e.g.
incompatible), a compatible one can be created by "baselining" both models
(follow up patch).

Let's provide a standardized interface to expand CPU models. This interface
can be used by tooling to get details about a specific CPU model in a
certain configuration, e.g. about the "host" model.
To take care of all architectures, two detail levels for an expansion
are introduced. Certain architectures might not support all detail levels.
While "full" will expand and indicate all relevant properties/features
of a CPU model, "static" expands to a static base CPU model, that will
never change between QEMU versions and therefore have the same features
when used under different compatibility machines.

The idea is simple - backup is "written-once" data. It is written block
by block and it is large enough. It would be nice to save storage
space and compress it.
The patch adds a flag to the qmp/hmp drive-backup command which enables
block compression. Compression should be implemented in the format driver
to enable this feature.
There are some limitations of the format driver to allow compressed writes.
We can write data only once. Though for backup this is perfectly fine.
These limitations are maintained by the driver and the error will be
reported if we are doing something wrong.

the VM.
We only have hmp commands savevm/loadvm, and qmp commands
xen-save-devices-state.
We use this new command for COLO:
1. suspend both primary vm and secondary vm
2. sync the state
3. resume both primary vm and secondary vm
In such case, we need to update all devices' state in any time.

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.

This modifies the nbd-server-start QMP command so that it
is possible to request use of TLS. This is done by adding
a new optional parameter "tls-creds" which provides the ID
of a previously created QCryptoTLSCreds object instance.
TLS is only supported when using an IPv4/IPv6 socket listener.

We didn't document x-cpu-throttle-initial/x-cpu-throttle-increment for
commands migrate-set-parameters and query-migrate-parameters.
Here we add the descriptions for these two options and fix the wrong example
for query-migrate-parameters qmp commands.
Besides, this will also fix the bug that we can't set x-cpu-throttle-initial
and x-cpu-throttle-increment through migrate-set-parameters qmp command.

This will start a mirror job from a named device to another named
device, its relation with drive-mirror is similar with blockdev-backup
to drive-backup.
In blockdev-mirror, the target node should be prepared by blockdev-add,
which will be responsible for assigning a name to the new node, so
we don't have 'node-name' parameter.

The CpuInfo struct is used only by the 'query-cpus' output
command, so we are free to modify it by adding fields (clients
are already supposed to ignore unknown output fields), or by
changing optional members to mandatory, while still keeping
QMP wire compatibility with older versions of qemu.
When qapi type CpuInfo was originally created for 0.14, we had
no notion of a flat union, and instead just listed a bunch of
optional fields with documentation about the mutually-exclusive
choice of which instruction pointer field(s) would be provided
for a given architecture. But now that we have flat unions and
introspection, it is better to segregate off which fields will
be provided according to the actual architecture. With this in
place, we no longer need the fields to be optional, because the
choice of the new 'arch' discriminator serves that role.
This has an additional benefit: the old all-in-one struct was
the only place in the code base that had a case-sensitive
naming of members 'pc' vs. 'PC'. Separating these spellings
into different branches of the flat union will allow us to add
restrictions against future case-insensitive collisions, since
that is generally a poor interface practice.

While in the long term we want throttling to be its own block filter
BDS, in the short term we want it to be part of the BB instead of a BDS;
even in the long term we may want legacy throttling to be automatically
tied to the BB.
blockdev-insert-medium and blockdev-remove-medium do not retain
throttling information in the BB (deliberately so). Therefore, using
them means tying this information to a BDS, which would break the model
described above. (The same applies to other flags such as
detect_zeroes.) We probably want to move this information to the BB or
its own filter BDS before blockdev-{insert,remove}-medium can be
considered completely stable.
Therefore, mark these functions experimental for the time being.

This patch keeps track of the minimum, maximum and average latencies
of I/O operations during a certain interval of time.
The values are exposed in the BlockDeviceTimedStats structure.
An option to define the intervals to collect these statistics will be
added in a separate patch.
