g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,

Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

It is possible to specify more than one VNC server on the command line,
either with an explicit ID or the auto-generated ones à la "default",
"vnc2", "vnc3", ...
It is not possible to change the password on one of these extra VNC
displays though. Fix this by adding a "display" parameter to the
"set_password" and "expire_password" QMP and HMP commands.
For HMP, the display is specified using the "-d" value flag.
For QMP, the schema is updated to explicitly express the supported
variants of the commands with protocol-discriminated unions.

This provides a foundation on which to convert simple HMP commands to
use QMP. The QMP implementation will generate formatted text targeted
for human consumption, returning it in the HumanReadableText data type.
The HMP command handler will simply print out the formatted string
within the HumanReadableText data type. Since this will be an entirely
formulaic action in the case of HMP commands taking no arguments, a
custom command handler is provided.
Thus instead of registering a 'cmd' callback for the HMP command, a
'cmd_info_hrt' callback is provided, which will simply be a pointer
to the QMP implementation.

Instead of invoking select_watchdog_action from both HMP and command line,
go directly from HMP to QMP and use QemuOpts as the intermediary for the

This makes -watchdog-action explicitly a shortcut for "-action watchdog",
so that "-watchdog-action" and "-action watchdog" override each other
based on the position on the command line; previously, "-action watchdog"

I noticed -cpu help printing enough trailing spaces to make the output
at least 84 characters wide. Looks ugly unless the terminal is wider.
Ugly or not, trailing spaces are stupid.
The culprit is this line in x86_cpu_list_entry():
qemu_printf("x86 %-20s %-58s\n", name, desc);
This prints a string with minimum field left-justified right before a
newline. Change it to
qemu_printf("x86 %-20s %s\n", name, desc);
which avoids the trailing spaces and is simpler to boot.
A search for the pattern with "git-grep -E '%-[0-9]+s\\n'" found a few
more instances. Change them similarly.

HMP command "change vnc" can take the password as argument, or prompt
for it:
(qemu) change vnc password 123
(qemu) change vnc password
Password: ***
(qemu)
This regressed in commit cfb5387a1d "hmp: remove "change vnc TARGET"
command", v6.0.0.
(qemu) change vnc passwd 123
Password: ***
(qemu) change vnc passwd
(qemu)
The latter passes NULL to qmp_change_vnc_password(), which is a no-no.
Looks like it puts the display into "password required, but none set"
state.
The logic error is easy to miss in review, but testing should've
caught it.
Fix the obvious way.

Simple unions predate flat unions. Having both complicates the QAPI
schema language and the QAPI generator. We haven't been using simple
unions in new code for a long time, because they are less flexible and
somewhat awkward on the wire.
To prepare for their removal, convert simple union TpmTypeOptions to
an equivalent flat one, with existing enum TpmType replacing implicit
enum TpmTypeOptionsKind. Adds some boilerplate to the schema, which
is a bit ugly, but a lot easier to maintain than the simple union
feature.

The kvm_available() function reports whether KVM support was
compiled into the QEMU binary; it returns the value of the
CONFIG_KVM define.
The only place in the codebase where we use this function is
in qmp_query_kvm(). Now that accelerators are based on QOM
classes we can instead use accel_find("kvm") and remove the
kvm_available() function.

Since commit 9894dc0cdc "char: convert
from GIOChannel to QIOChannel", the first argument to the watch callback
can actually be a QIOChannel, which is not a GIOChannel (but a QEMU
Object).
Even though we never used that pointer, change the callback type to warn
the users. Possibly a better fix later, we may want to store the
callback and call it from intermediary functions.

The `aio-max-batch` parameter will be propagated to AIO engines
and it will be used to control the maximum number of queued requests.
When there are in queue a number of requests equal to `aio-max-batch`,
the engine invokes the system call to forward the requests to the kernel.
This parameter allows us to control the maximum batch size to reduce
the latency that requests might accumulate while queued in the AIO
engine queue.
If `aio-max-batch` is equal to 0 (default value), the AIO engine will
use its default maximum batch size value.

When the management layer queries a binary built using --disable-tpm
for TPM devices, it gets confused by getting empty responses:
{ "execute": "query-tpm" }
{
"return": [
]
}
{ "execute": "query-tpm-types" }
{
"return": [
]
}
{ "execute": "query-tpm-models" }
{
"return": [
]
}
To make it clearer by returning an error:
- Make the TPM QAPI schema conditional
All of tpm.json is now 'if': 'defined(CONFIG_TPM)'.
- Adapt the HMP command
- Remove stubs which became unnecessary
The management layer now gets a 'CommandNotFound' error:
{ "execute": "query-tpm" }
{
"error": {
"class": "CommandNotFound",
"desc": "The command query-tpm has not been found"
}
}

Commit f61fe11aa6 broke hmp_loadvm() by adding an incorrect negation
when converting from 0/-errno return values to a bool value. The result
is that loadvm resumes the VM now if it failed and keeps it stopped if
it failed. Fix it to restore the old behaviour and do it the other way
around.
