QEMU would not start when trying to create two UFS host controllers and
a UFS logical unit for each with the following options:
-device ufs,id=bus0 \
-device ufs-lu,drive=drive1,bus=bus0,lun=0 \
-device ufs,id=bus1 \
-device ufs-lu,drive=drive2,bus=bus1,lun=0 \
This is because the same ID string ("0:0:0/scsi-disk") is generated
for both UFS logical units.
To fix this issue, prepend the parent pci device's path to make
the ID string unique.

The virtio-sound device is currently not migratable. QEMU crashes
on the source machine at some point during the migration with a
segmentation fault.
Even with this bug fixed, the virtio-sound device doesn't migrate
the state of the audio streams. For example, running streams leave
the device on the destination machine in a broken condition.
Mark the device as unmigratable until these issues have been fixed.

`kvm_enabled()` is compiled down to `0` and short-circuit logic is
used to remove references to undefined symbols at the compile stage.
Some build configurations with some compilers don't attempt to
simplify this logic down in some cases (the pattern appears to be
that the literal false must be the first term) and this was causing
some builds to emit references to undefined symbols.
An example of such a configuration is clang 16.0.6 with the following
configure: ./configure --enable-debug --without-default-features
--target-list=x86_64-softmmu --enable-tcg-interpreter

QEMU crashes on exit when a virtio-sound device has failed to
realise. Its vmstate field was not cleaned up properly with
qemu_del_vm_change_state_handler().
This patch changes the realize() order as
1. Validate the given configuration values (no resources allocated
by us either on success or failure)
2. Try AUD_register_card() and return on failure (no resources allocated
by us on failure)
3. Initialize vmstate, virtio device, heap allocations and stream

The VIA integrated south bridge chips combine several functions and
allow routing their interrupts to any of the ISA IRQs also allowing
multiple sources to share the same ISA IRQ. E.g. pegasos2 firmware
configures everything to use IRQ 9 but amigaone routes them to
separate ISA IRQs so the current simplified routing does not work.
Bring back via_isa_set_irq() and change it to take the component that
wants to change an IRQ and keep track of interrupt status of each
source separately and do the mapping to ISA IRQ within the ISA bridge.
This may not handle cases when an ISA IRQ is controlled by devices
directly, not going through via_isa_set_irq() such as serial, parallel
or keyboard but these IRQs being conventionally fixed are not likely
to be change by guests or share with other devices so this does not
cause a problem in practice.

Passing an uninitialised list to visit_start_list() happens to work for
the QObject output visitor because it treats the pointer as an opaque
value and never dereferences it, but the string output visitor expects a
valid list to check if it has more than one element.
The existing code crashes with the string output visitor if the
uninitialised value is non-NULL. Passing an explicit NULL would fix the
crash, but still result in wrong output.
Rework get_prop_array() so that it conforms to the expectations that the
string output visitor has. This includes building a real list first and
using visit_next_list() to iterate it.

Commit 49554856f0 fixed a problem, where TPM devices were not appearing
in the FDT, by delaying the FDT creation up until virt_machine_done().
This create a side effect (see gitlab #1925) - devices that need access
to the '/chosen' FDT node during realize() stopped working because, at
that point, we don't have a FDT.
This happens because our FDT creation is monolithic, but it doesn't need
to be. We can add the needed FDT components for realize() time and, at
the same time, do another FDT round where we account for dynamic sysbus
devices. In other words, the problem fixed by 49554856f0 could also be
fixed by postponing only create_fdt_sockets() and its dependencies,
leaving everything else from create_fdt() to be done during init().
Split the FDT creation in two parts:
- create_fdt(), now moved back to virt_machine_init(), will create FDT
nodes that doesn't depend on additional (dynamic) devices from the
sysbus;
- a new finalize_fdt() step is added, where create_fdt_sockets() and
friends is executed, accounting for the dynamic sysbus devices that
were added during realize().
This will make both use cases happy: TPM devices are still working as
intended, and devices such as 'guest-loader' have a FDT to work on
during realize().

The via-ide device currently attempts to set the default BAR addresses to the

BARS 1-4 do not set the bottom 2 bits to PCI_BASE_ADDRESS_SPACE_IO, and
secondly the initial PCI bus reset clears the values of all PCI device BARs
after the device itself has been reset.
Remove the setting of the default BAR addresses from via_ide_reset() to ensure
there is no doubt that these values are never exposed to the guest.
