The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP. It should not be used
elsewhere.
The only remaining user in qemu-option.c is qemu_opts_parse(). Is it
used in QMP context? If not, we can simply replace
qerror_report_err() by error_report_err().
The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.
The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.
Remaining uses:
* drive_def(): Command line -drive and such, HMP drive_add and pci_add
* hmp_chardev_add(): HMP chardev-add
* monitor_parse_command(): HMP core
* tmp_config_parse(): Command line -tpmdev
* net_host_device_add(): HMP host_net_add
* net_client_parse(): Command line -net and -netdev
* qemu_global_option(): Command line -global
* vnc_parse_func(): Command line -display, -vnc, default display, HMP
change, QMP change. Bummer.
* qemu_pci_hot_add_nic(): HMP pci_add
* usb_net_init(): Command line -usbdevice, HMP usb_add
Propagate errors through qemu_opts_parse(). Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err(). Switch all non-QMP users outside tests to it.

A QOM property can be parsed as enum using the visit_type_enum()
helper function, but this forces callers to use the more complex
generic object_property_add() method when registering it. It
also requires that users of that object have access to the
string map when they want to read the property value.
This patch introduces a specialized object_property_add_enum()
method which simplifies the use of enum properties, so the
setters/getters directly get passed the int value.
typedef enum {
MYDEV_TYPE_FROG,
MYDEV_TYPE_ALLIGATOR,
MYDEV_TYPE_PLATYPUS,
MYDEV_TYPE_LAST
} MyDevType;
Then provide a table of enum <-> string mappings
static const char *const mydevtypemap[MYDEV_TYPE_LAST + 1] = {
[MYDEV_TYPE_FROG] = "frog",
[MYDEV_TYPE_ALLIGATOR] = "alligator",
[MYDEV_TYPE_PLATYPUS] = "platypus",
[MYDEV_TYPE_LAST] = NULL,
};
Assuming an object struct of
typedef struct {
Object parent_obj;
MyDevType devtype;
...other fields...
} MyDev;
The property can then be registered as follows:
static int mydev_prop_get_devtype(Object *obj,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
return dev->devtype;
}
static void mydev_prop_set_devtype(Object *obj,
int value,
Error **errp G_GNUC_UNUSED)
{
MyDev *dev = MYDEV(obj);
dev->devtype = value;
}
object_property_add_enum(obj, "devtype",
mydevtypemap, "MyDevType",
mydev_prop_get_devtype,
mydev_prop_set_devtype,
NULL);
Note there is no need to check the range of 'value' in
the setter, because the string->enum conversion code will
have already done that and reported an error as required.

It is reasonably common to want to create an object, set a
number of properties, register it in the hierarchy and then
mark it as complete (if a user creatable type). This requires
quite a lot of error prone, verbose, boilerplate code to achieve.
First a pair of functions object_set_props() / object_set_propv()
are added which allow for a list of objects to be set in
one single API call.
Then object_new_with_props() / object_new_with_propv() constructors
are added which simplify the sequence of calls to create an
object, populate properties, register in the object composition
tree and mark the object complete, into a single method call.
Usage would be:
Error *err = NULL;
Object *obj;
obj = object_new_with_propv(TYPE_MEMORY_BACKEND_FILE,
object_get_objects_root(),
"hostmem0",
&err,
"share", "yes",
"mem-path", "/dev/shm/somefile",
"prealloc", "yes",
"size", "1048576",
NULL);
Note all property values are passed in string form and will
be parsed into their required data types, using normal QOM
semantics for parsing from string format.

Add new "arg" sub-argument to the --semihosting-config allowing the user

by UHI semihosting to construct argc and argv.
Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).
If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

Add a string property that specifies the primary boot cpu. All CPUs
except the one selected will start-powered-off. This allows for elf
boots on any CPU, which prepares support for booting R5 elfs directly
on the R5 processors.

The CPUs currently supported by zynqmp are the APU (application

"cpus" in ambiguous. Preface the variables with "APU" accordingly, to

Commit 691a0c9c introduced a mechanism by which QEMU_CLOCK_HOST can
notify other parts of the emulator when the host clock has jumped
backward. This is used to avoid stalling timers that were scheduled
based on the host clock.
However, if the host clock jumps forward, then timers that were
scheduled based on the host clock may fire rapidly and cause other
problems. For example, the mc146818rtc periodic timer will block
execution of the VM and consume host CPU while firing every interrupt
for the time period that was skipped by the host clock.
To correct that problem, this commit fires the reset notification if the
host clock jumps forward by more than a hard-coded limit. The limit is
currently set to a value of 60 seconds, which should be small enough to
prevent excessive timer loops, but large enough to avoid frequent resets
in idle VMs.

We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.
This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.
This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

The linux tap and macvtap backends can be told to parse vnet headers
according to little or big endian. This is done through the TUNSETVNETLE

Setting QEMU_AUDIO_LOG_TO_MONITOR=1 can crash qemu (if qemu tries to log
to the monitor before it's being initialized), and also nothing else in
qemu logs to the monitor.
This log to monitor feature was the last thing that used the default_mon
variable, so I removed it too (as using it can cause problems).

We store all struct types in an array of static size without ever
checking whether we overrun it. Of course some day someone (like me
in another, ancient ALSA enabling patch set) will run into the limit
without realizing it.
So let's make the allocation dynamic. We already know the number of
structs that we want to allocate, so we only need to pass the variable
into the respective piece of code.
Also, to ensure we don't accidently overwrite random memory, add some
asserts to sanity check whether a thunk is actually part of our array.
