These options likely do not work as expected as soon as the user
tries to use more than one network interface at once. The parameters
have been marked as deprecated since QEMU v2.6, so users had plenty
of time to move their scripts to the new syntax. Time to remove the
old parameters now.

kexec/kdump as well as the bootloader use a subcode of diagnose 308
that is supposed to reset the I/O subsystem but not comprise a full
"reboot". With the latest refactoring this is now broken when
-no-reboot is used or when libvirt acts on a reboot QMP event, for
example a virt-install from iso images.
We need to mark these "subsystem resets" as special.

With this flag, kvm allows guest to control host CPU power state. This
increases latency for other processes using same host CPU in an
unpredictable way, but if decreases idle entry/exit times for the
running VCPU, so to use it QEMU needs a hint about whether host CPU is
overcommitted, hence the flag name.
Follow-up patches will expose this capability to guest
(using mwait leaf).

We currently have got three ways of turning on the HAX accelerator:
"-machine accel=hax", "-accel hax" and "-enable-hax". That's really
confusing and overloaded. Since "-accel" is our preferred way to enable
an accelerator nowadays, and "-accel hax" is even less to type than
"-enable-hax", let's deprecate the "-enable-hax" option now.
Note: While "-enable-kvm" is available since a long time and can hardly be
removed since it is used in a lot of upper layer tools and scripts, the
"-enable-hax" option is still rather new and not very widespread yet, so
I think that it should be OK if we remove this in a couple of releases again
(we'll see whether someone complains after seeing the deprecation message -
then we could still reconsider to keep it if there a well-founded reasons).

some users when using --daemonize expect that QEMU will parse CLI options,
initialize VM and only then complete daemonzation by signalling lead
process to exit and start listening on monitor socket. So users treat
parent process exit as sync point to connect to QEMU's monitor.
That however doesn't work when --preconfig options is used, since it
provides monitor before completing daemonization and expects user to
issue exit-preconfig command when additional configuration via monitor
is finished. We also can't move completing daemonization before
preconfig monitor becomes available, since that would imply:
* partially loosing ability to configure QEMU instance in --preconfig
mode since QEMU might drop privileges, chroot and do other things
when daemonization is completed
* lead to loss of error messages in case they would happen after
daemonization
Be proactive now and make options mutually exclusive, so users would
get clear error message instead of waiting for lead process exit
indefinitely before connecting to monitor.
PS:
In case someone would come up with usecase where both options should
be enabled at the same time we could drop this restriction as far
as daemonization point is left where it is now (os_setup_post).

After 047f7038f5 it is possible for event loop to run two
times. First time whilst parsing command line options (the idea
is to bring up monitor early so that management applications can
tweak config before machine is initialized). And the second time
is after everything is set up (this is the usual place). In both
cases the event loop is called as main_loop_wait(nonblocking =
false) which causes the event loop to block until at least one
event occurred.
Now, consider that somebody (i.e. libvirt) calls us with
-daemonize. This operation is split in two steps. The main()
calls os_daemonize() which fork()-s and then waits in read()
until child notifies it via write():
/qemu.git $ ./x86_64-softmmu/qemu-system-x86_64 -S -daemonize \
-no-user-config -nodefaults -nographic
main(): child:
os_daemonize():
read(pipe[0])
main_loop():
main_loop_wait(false)
os_setup_post():
write(pipe[1])
main_loop():
main_loop_wait(false)
Here it can be clearly seen that main() does not exit until an
event occurs, but at the same time nobody will touch the monitor
socket until their exec("qemu-system-*") finishes. So the whole
thing deadlocks.
The solution is to not call main_loop_wait() unless --preconfig was
specified (in which case caller knows they must connect to the
socket before exec() finishes).
Patch also fixes hang when -nodefaults option is used, which were
causing QEMU hang in the early main_loop_wait() indefinitely by
the same means (not calling main_loop_wait() unless --preconfig
is present on CLI)

This option allows pausing QEMU in the new RUN_STATE_PRECONFIG state,
allowing the configuration of QEMU from QMP before the machine jumps
into board initialization code of machine_run_board_init()
The intent is to allow management to query machine state and additionally
configure it using previous query results within one QEMU instance
(i.e. eliminate the need to start QEMU twice, 1st to query board specific
parameters and 2nd for actual VM start using query results for
additional parameters).
The new option complements -S option and could be used with or without
it. The difference is that -S pauses QEMU when the machine is completely
initialized with all devices wired up and ready to execute guest code
(QEMU needs only to unpause VCPUs to let guest execute its code),
while the "preconfig" option pauses QEMU early before board specific init
callback (machine_run_board_init) is executed and allows the configuration
of machine parameters which will be used by board init code.
When early introspection/configuration is done, command 'exit-preconfig'
should be used to exit RUN_STATE_PRECONFIG and transition to the next
requested state (i.e. if -S is used then QEMU will pause the second
time when board/device initialization is completed or start guest
execution if -S isn't provided on CLI)
PS:
Initially 'preconfig' is planned to be used for configuring numa
topology depending on board specified possible cpus layout.

The consoles ("sclpconsole" and "sclplmconsole") can only be configured
with "-device" and "-chardev" so far. Other machines use the convenience
option "-serial" to configure the default consoles, even for virtual
consoles like spapr-vty on the pseries machine. So let's support this
option on s390x, too. This way we can easily enable the serial console
here again with "-nodefaults", for example:
qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio
... which is way shorter than typing:
qemu-system-s390x -no-shutdown -nographic -nodefaults \
-chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \
-mon chardev=c1
The -serial parameter can also be used if you only want to see the QEMU
monitor on stdio without using -nodefaults, but not the console output.
That's something that is pretty impossible with the current code today:
qemu-system-s390x -no-shutdown -nographic -serial none
While we're at it, this patch also maps the second -serial option to the
"sclplmconsole", so that there is now an easy way to configure this second
console on s390x, too, for example:
qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio
Additionally, the new code is also smaller than the old one and we have
less s390x-specific code in vl.c :-)
I've also checked that migration still works as expected by migrating
a guest with console output back and forth between a qemu-system-s390x
that has this patch and an instance without this patch.

There are many places where the monitor initializes its globals:
- monitor_init_qmp_commands() at the very beginning
- single function to init monitor_lock
- in the first entry of monitor_init() using "is_first_init"
Unify them a bit.
monitor_lock is not used before monitor_init() (as confirmed by code
analysis and gdb watchpoints); so we are safe delaying what was a
constructor-time initialization of the mutex into the later first call
to monitor_init().

With all targets defining CPU_RESOLVING_TYPE, refactor
cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model)
so that callers won't have to know internal resolving cpu
type. Place it in exec.c so it could be called from both
target independed vl.c and *-user/main.c.
That allows us to stop abusing cpu type from
MachineClass::default_cpu_type
as resolver class in vl.c which were confusing part of
cpu_parse_cpu_model().
Also with new parse_cpu_model(), the last users of cpu_init()
in null-machine.c and bsd/linux-user targets could be switched
to cpu_create() API and cpu_init() API will be removed by
follow up patch.
With no longer users left remove MachineState::cpu_model field,
new code should use MachineState::cpu_type instead and
leave cpu_model parsing to generic code in vl.c.

Since commit 67a1de0d19 there is no space anymore between the
version number and the parentheses when running configure with
--with-pkgversion=foo :
$ qemu-system-s390x --version
QEMU emulator version 2.11.50(foo)
But the space is included when building without that option
when building from a git checkout:
$ qemu-system-s390x --version
QEMU emulator version 2.11.50 (v2.11.0-1494-gbec9c64-dirty)
The same confusion exists with the "query-version" QMP command.
Let's fix this by introducing a proper QEMU_FULL_VERSION definition
that includes the space and parentheses, while the QEMU_PKGVERSION
should just cleanly contain the package version string itself.
Note that this also changes the behavior of the "query-version" QMP
command (the space and parentheses are not included there anymore),
but that's supposed to be OK since the strings there are not meant
to be parsed by other tools.

Commit 00d09fdbba ("vl: pause vcpus before
stopping iothreads") and commit dce8921b2b
("iothread: Stop threads before main() quits") tried to work around the
fact that emulation was still active during termination by stopping
iothreads. They suffer from race conditions:
1. virtio_scsi_handle_cmd_vq() racing with iothread_stop_all() hits the
virtio_scsi_ctx_check() assertion failure because the BDS AioContext
has been modified by iothread_stop_all().
2. Guest vq kick racing with main loop termination leaves a readable
ioeventfd that is handled by the next aio_poll() when external
clients are enabled again, resulting in unwanted emulation activity.
This patch obsoletes those commits by fully disabling emulation activity
when vcpus are stopped.
Use the new vm_shutdown() function instead of pause_all_vcpus() so that
vm change state handlers are invoked too. Virtio devices will now stop
their ioeventfds, preventing further emulation activity after vm_stop().
Note that vm_stop(RUN_STATE_SHUTDOWN) cannot be used because it emits a
QMP STOP event that may affect existing clients.
It is no longer necessary to call replay_disable_events() directly since
vm_shutdown() does so already.
Drop iothread_stop_all() since it is no longer used.

There are two issues with the documentation of the --balloon parameter:
First, "--balloon none" is simply doing nothing. Even if a machine had a
balloon device by default, this option is not disabling anything, it is
simply ignored. Thus let's simply drop this option from the documentation
to avoid to confuse the users (but keep the code in vl.c for backward
compatibility).
Second, the documentation claims that "--balloon virtio" is the default
mode, but this is not true anymore since commit 382f074371.
Since that commit, the option also has no real use case anymore, since
you can simply use "--device virtio-balloon" nowadays instead. Thus to
simplify our complex parameter zoo a little bit, let's deprecate the
the parameter now and tell the user to use "--device virtio-balloon"
instead.

The legacy "-net" option can be quite confusing for the users since most
people do not expect to get a "vlan" hub between their emulated guest
hardware and the host backend. But so far, we are also not able to get
rid of "-net" completely, since it is the only way to configure on-board
NICs that can not be instantiated via "-device" yet. It's also a little
bit shorter to type "-net nic -net tap" instead of "-device xyz,netdev=n1
-netdev tap,id=n1".
So what we need is a new convenience option that is shorter to type than
the full -device + -netdev stuff, and which can be used to configure the
on-board NICs that can not be handled via -device yet. Thus this patch now
provides such a new option "--nic": It adds an entry in the nd_table to
configure a on-board / default NIC, creates a host backend and connects
the two directly, without a confusing "vlan" hub inbetween.

The previous commit improved compile time by including less of the

everything.
Move everything but include directives from qapi-schema.json to new
sub-module qapi/misc.json, then include just the "misc" shard where
possible.
It's possible everywhere, except:
* monitor.c needs qmp-command.h to get qmp_init_marshal()
* monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need
qapi-event.h to get enum QAPIEvent

This patch is the s390 implementation of guest crash information,
similar to commit d187e08dc4 ("i386/cpu: add crash-information QOM
property") and the related commits. We will detect several crash
reasons, with the "disabled wait" being the most important one, since
this is used by all s390 guests as a "panic like" notification.
Demonstrate these ways with examples as follows.
1. crash-information QOM property;
Run qemu with -qmp unix:qmp-sock,server, then use utility "qmp-shell"
to execute "qom-get" command, and might get the result like,
(QEMU) (QEMU) qom-get path=/machine/unattached/device[0] \
property=crash-information
{"return": {"core": 0, "reason": "disabled-wait", "psw-mask": 562956395872256, \
"type": "s390", "psw-addr": 1102832}}
2. GUEST_PANICKED event reporting;
Run qemu with a socket option, and telnet or nc to that,
-chardev socket,id=qmp,port=4444,host=localhost,server \
-mon chardev=qmp,mode=control,pretty=on \
Negotiating the mode by { "execute": "qmp_capabilities" }, and the crash
information will be reported on a guest crash event like,
{
"timestamp": {
"seconds": 1518004739,
"microseconds": 552563
},
"event": "GUEST_PANICKED",
"data": {
"action": "pause",
"info": {
"core": 0,
"psw-addr": 1102832,
"reason": "disabled-wait",
"psw-mask": 562956395872256,
"type": "s390"
}
}
}
3. log;
Run qemu with the parameters: -D <logfile> -d guest_errors, to
specify the logfile and log item. The results might be,
Guest crashed on cpu 0: disabled-wait

Commit dce8921b2b ("iothread: Stop threads
before main() quits") introduced iothread_stop_all() to avoid the
following virtio-scsi assertion failure:
assert(blk_get_aio_context(d->conf.blk) == s->ctx);
Back then the assertion failed because when bdrv_close_all() made
d->conf.blk NULL, blk_get_aio_context() returned the global AioContext
instead of s->ctx.
The same assertion can still fail today when vcpus submit new I/O
requests after iothread_stop_all() has moved the BDS to the global
AioContext.
This patch hardens the iothread_stop_all() approach by pausing vcpus
before calling iothread_stop_all().
Note that the assertion failure is a race condition. It is not possible
to reproduce it reliably.

The option have been marked as deprecated since QEMU 2.10, and so far
nobody complained that the host, serial, disk and net options are urgently
required anymore. So let's now get rid at least of this legacy pile, to
simplify the usb code quite a bit.
This patch removes the usbdevices host, serial, disk and net. These devices
use their own complicated parameter parsing mechanisms, so they are just
ugly to maintain, without real benefit for the users (the users can use the
corresponding "-device" parameters instead which have the same complexity
as the "-usbdevice" devices here).
Note that the other rather simple -usbdevice options (mouse, tablet, etc.)
are not removed yet (the code is really simple here, so it does not hurt
much to keep it), as well as the two devices "braille" and "bt" which are
easier to use with -usbdevice than with -device.

[kraxel] delete some usb_host_device_open() leftovers.

Drop no_frame flag from sdl_display_init argument list, use a global
variable instead. This is temporary until -no-frame support is dropped
altogether when we remove sdl1 support.
Remove any traces of noframe from sdl2 code. It is just dead code as
sdl2 doesn't support the SDL_NOFRAME window flag any more.

Remove dependency of possible_cpus on 1st CPU instance,
which decouples configuration data from CPU instances that
are created using that data.
Also later it would be used for enabling early cpu to numa node
configuration at runtime qmp_query_hotpluggable_cpus() should
provide a list of available cpu slots at early stage,
before machine_init() is called and the 1st cpu is created,
so that mgmt might be able to call it and use output to set
numa mapping.
Use MachineClass::possible_cpu_arch_ids() callback to set
cpu type info, along with the rest of possible cpu properties,
to let machine define which cpu type* will be used.
* for SPAPR it will be a spapr core type and for ARM/s390x/x86
a respective descendant of CPUClass.
Move parse_numa_opts() in vl.c after cpu_model is parsed into
cpu_type so that possible_cpu_arch_ids() would know which
cpu_type to use during layout initialization.

It's been marked as deprecated since QEMU v2.10.0, and so far nobody
complained that we should keep it, so let's remove this legacy option
now to simplify the code quite a bit.
