Factor out slot status check into a helper function. Add an additional
check after completing transfers. This is needed in case a guest
queues multiple transfers in a row and a device unplug happens while
qemu processes them.

I've got a case where usbredir_write manages to call back into itself
via spice; this patch causes the recursion to fail (0 bytes) the write;
this seems to avoid the deadlock I was previously seeing.
I can't say I fully understand the interaction of usbredir and spice;
but there are a few similar guards in spice and usbredir
to catch other cases especially onces also related to spice_server_char_device_wakeup
This case seems to be triggered by repeated migration+repeated
reconnection of the viewer; but my debugging suggests the migration
finished before this hits.
The backtrace of the hang looks like:
reds_handle_ticket
reds_handle_other_links
reds_channel_do_link
red_channel_connect
spicevmc_connect
usbredir_create_parser
usbredirparser_do_write
usbredir_write
qemu_chr_fe_write
qemu_chr_write
qemu_chr_write_buffer
spice_chr_write
spice_server_char_device_wakeup
red_char_device_wakeup
red_char_device_write_to_device
vmc_write
usbredirparser_do_write
usbredir_write
qemu_chr_fe_write
qemu_chr_write
qemu_chr_write_buffer
qemu_mutex_lock_impl
and we fail as we lang through qemu_chr_write_buffer's lock
twice.

Provides a blocking call to read a character from the console using
semihosting.chardev, if specified. This takes some careful command
line options to use stdio successfully as the serial ports, monitor
and semihost all want to use stdio. Here's a sample set of command
line options which share stdio between semihost, monitor and serial
ports:
qemu \
-chardev stdio,mux=on,id=stdio0 \
-serial chardev:stdio0 \
-semihosting-config enable=on,chardev=stdio0 \
-mon chardev=stdio0,mode=readline
This creates a chardev hooked to stdio and then connects all of the
subsystems to it. A shorter mechanism would be good to hear about.

The Chardev events are listed in the QEMUChrEvent enum.
By using the enum in the IOEventHandler typedef we:
- make the IOEventHandler type more explicit (this handler
process out-of-band information, while the IOReadHandler
is in-band),
- help static code analyzers.

The proper way to do that would be to use device_class_set_parent_realize(),
but defining a Pnv8PsiClass and a Pnv9PsiClass types with a parent_realize
pointer adds a fair amount of code. Calling pnv_psi_realize() explicitely
is fine for now.

Now that the spapr and pnv machines do set the "xive-fabric" link, the
use of the XIVE fabric pointer becomes mandatory. This is checked with
an assert() in a new realize hook. Since the XIVE router is realized at
machine init for the all the machine's life time, no risk to abort an
already running guest (ie. not a hotplug path).

In order to get rid of qdev_get_machine(), first add a pointer to the
XIVE fabric under the XIVE router and make it configurable through a
QOM link property.
Configure it in the spapr and pnv machine. In the case of pnv, the XIVE
routers are under the chip, so this is done with a QOM alias property of
the POWER9 pnv chip.

spapr_match_nvt() is a XIVE operation and is used by the machine to
look for a matching target when an event notification is being
delivered. An assert checks that spapr_match_nvt() is called only when
the machine has selected the XIVE interrupt mode but it is redundant
with the XIVE_PRESENTER() dynamic cast.
Apply the cast to spapr->active_intc and remove the assert.

The number of CPU chips of the powernv machine is configurable through a
"num-chips" property. This doesn't fit well with the CPU topology, eg.
some configurations can come up with more CPUs than the maximum of CPUs
set in the toplogy. This causes assertion to be hit with mttcg:
-machine powernv,num-chips=2 -smp cores=2 -accel tcg,thread=multi
ERROR:
tcg/tcg.c:789:tcg_register_thread: assertion failed: (n < ms->smp.max_cpus)
Aborted (core dumped)
Mttcg mandates the CPU topology to be dimensioned to the actual number
of CPUs, depending on the number of chips the user asked for. That is,
'-machine num-chips=N' should always have a '-smp' companion with a
topology that meats the resulting number of CPUs, typically
'-smp sockets=N'.
It thus seems that "num-chips" doesn't bring anything but forcing the user
to specify the requested number of chips on the command line twice. Simplify
the command line by computing the number of chips based on the CPU topology
exclusively. The powernv machine isn't a production thing ; it is mostly
used by developpers to prepare the bringup of real HW. Because of this and
for simplicity, this deliberately ignores the official deprecation process
and dumps "num-chips" right away : '-smp sockets=N' is now the only way to
control the number of CPU chips.
This is done at machine init because smp_parse() is called after instance
init.

A pseries guest can be run as a secure guest on Ultravisor-enabled
POWER platforms. When such a secure guest is reset, we need to
release/reset a few resources both on ultravisor and hypervisor side.
This is achieved by invoking this new ioctl KVM_PPC_SVM_OFF from the
machine reset path.
As part of this ioctl, the secure guest is essentially transitioned
back to normal mode so that it can reboot like a regular guest and
become secure again.
This ioctl has no effect when invoked for a normal guest. If this ioctl
fails for a secure guest, the guest is terminated.

Hi,
QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
the pointer points to an Object.
There are a few places where such substitution isn't possible. For
those places, it seems reasonable to use a specific setter method
instead, and keep the user_creatable = false. In other places,
proper usage of qdev or other facilies is the solution.
The serial code wasn't converted to qdev, which makes it a bit more
archaic to deal with. Let's convert it first, so we can more easily
embed it from other devices, and re-export some properties and drop
QDEV_PROP_PTR usage.
