DEVICE_DEL is currently emitted when a Device is unparented, as
opposed to when it is finalized. The main design motivation for this
seems to be that after unparent()/unrealize(), the Device is no
longer visible to the guest, and thus the operation is complete
from the perspective of management.
However, there are cases where remaining host-side cleanup is also
pertinent to management. The is generally handled by treating these
resources as aspects of the "backend", which can be managed via
separate interfaces/events, such as blockdev_add/del, netdev_add/del,
object_add/del, etc, but some devices do not have this level of
compartmentalization, namely vfio-pci, and possibly to lend themselves
well to it.
In the case of vfio-pci, the "backend" cleanup happens as part of
the finalization of the vfio-pci device itself, in particular the
cleanup of the VFIO group FD. Failing to wait for this cleanup can
result in tools like libvirt attempting to rebind the device to
the host while it's still being used by VFIO, which can result in
host crashes or other misbehavior depending on the host driver.
Deferring DEVICE_DEL still affords us the ability to manage backends
explicitly, while also addressing cases like vfio-pci's, so we
implement that approach here.
An alternative proposal involving having VFIO emit a separate event
to denote completion of host-side cleanup was discussed, but the
prevailing opinion seems to be that it is not worth the added
complexity, and leaves the issue open for other Device implementations
to solve in the future.

This reverts commit abed886ec6.
This patch originally addressed an issue where a DEVICE_DELETED
event could be emitted (in device_unparent()) before a Device's
QemuOpts were cleaned up (in device_finalize()), leading to a
"duplicate ID" error if management attempted to immediately add
a device with the same ID in response to the DEVICE_DELETED event.
An alternative will be implemented in a subsequent patch where we
defer the DEVICE_DELETED event until device_finalize(), which would
also prevent the race, so we revert the original fix in preparation.

device_unparent(dev, ...) is called when a device is unparented,
either directly, or as a result of a parent device being
finalized, and handles some final cleanup for the device. Part
of this includes emiting a DEVICE_DELETED QMP event to notify
management, which includes the device's path in the composition
tree as provided by object_get_canonical_path().
object_get_canonical_path() assumes the device is still connected
to the machine/root container, and will assert otherwise, but
in some situations this isn't the case:
If the parent is finalized as a result of object_unparent(), it
will still be attached to the composition tree at the time any
children are unparented as a result of that same call to
object_unparent(). However, in some cases, object_unparent()
will complete without finalizing the parent device, due to
lingering references that won't be released till some time later.
One such example is if the parent has MemoryRegion children (which
take a ref on their parent), who in turn have AddressSpace's (which
take a ref on their regions), since those AddressSpaces get cleaned
up asynchronously by the RCU thread.
In this case qdev:device_unparent() may be called for a child Device
that no longer has a path to the root/machine container, causing
object_get_canonical_path() to assert.
Fix this by storing the canonical path during realize() so the
information will still be available for device_unparent() in such
cases.

Calculating default node-ids for CPUs in possible_cpu_arch_ids()
is rather fragile since defaults calculation uses nb_numa_nodes but
callback might be potentially called early before all -numa CLI
options are parsed, which would lead to cpus assigned only upto
nb_numa_nodes at the time possible_cpu_arch_ids() is called.
Issue was introduced by
(7c88e65 numa: mirror cpu to node mapping in MachineState::possible_cpus)
and for example CLI:
-smp 4 -numa node,cpus=0 -numa node
would set props.node-id in possible_cpus array for every non
explicitly mapped CPU to the first node.
Issue is not visible to guest nor to mgmt interface due to
1) implictly mapped cpus are forced to the first node in
case of partial mapping
2) in case of default mapping possible_cpu_arch_ids() is
called after all -numa options are parsed (resulting
in correct mapping).
However it's fragile to rely on late execution of
possible_cpu_arch_ids(), therefore add machine specific
callback that returns node-id for CPU and use it to calculate/
set defaults at machine_numa_finish_init() time when all -numa
options are parsed.

The current code recursively applies global properties from child up to
parent types. This can cause properties passed with the -global option to
be silently overridden by internal compat properties.
This is exactly what happened with virtio-*-pci drivers since commit:
"9a4c0e220d8a hw/virtio-pci: fix virtio behaviour"
Passing -device virtio-blk-pci.disable-modern=off had no effect on 2.6
machine types because the internal virtio-pci.disable-modern=on compat
property always prevailed.
A workaround for this was included with commit 0bcba41f ("machine:
Convert abstract typename on compat_props to subclass names").
This patch fixes the issue properly by reversing the logic: we now go
through the global property list and, for each property, we check if it
is applicable to the device.
This results in compat properties being applied first, in the order they
appear in the HW_COMPAT_* macros, followed by global properties, in the
order they appear on the command line.

In some situations it's useful to have a qdev property which doesn't
automatically set its default value when qdev_property_add_static is
called (for instance when the default value is not constant).
Support this by adding a flag to the Property struct indicating
whether to set the default value. This replaces the existing test
for whether the PropertyInfo set_default_value function pointer is
NULL, and we set the .set_default field to true for all those cases
of struct Property which use a PropertyInfo with a non-NULL
set_default_value, so behaviour remains the same as before.
This gives us the semantics of:
* if .set_default is true, then .info->set_default_value must
be not NULL, and .defval is used as the the default value of
the property
* otherwise, the property system does not set any default, and
the field will retain whatever initial value it was given by
the device's .instance_init method
We define two new macros DEFINE_PROP_SIGNED_NODEFAULT and
DEFINE_PROP_UNSIGNED_NODEFAULT, to cover the most plausible use cases
of wanting to set an integer property with no default value.

We have HW_COMPAT_*, however that's only bound to machines, not other
things (like accelerators). Behind it, it was register_compat_prop()
that played the trick. Let's export the function for further use
outside HW_COMPAT_* magic.
Meanwhile, move it to qdev-properties.c where seems more proper (since
it'll be used not only in machine codes).

It fixes/add missing _PXM object for non mapped CPU (x86)
and missing fdt node (virt-arm).
It ensures that possible_cpus contains complete mapping if
numa is enabled by the time machine_init() is executed.
As result non completely mapped CPUs:
1) appear in ACPI/fdt blobs
2) QMP query-hotpluggable-cpus command shows bound nodes for such CPUs
3) allows to drop checks for has_node_id in numa only code,
reducing number of invariants incomplete mapping could produce
4) moves fixup/implicit node init from runtime numa_cpu_pre_plug()
(when CPU object is created) to machine_numa_finish_init() which
helps to fix [1, 2] and make possible_cpus complete source
of numa mapping available even before CPUs are created.

there is no need use cpu_index_to_instance_props() for setting
default cpu -> node mapping. Generic machine code can do it
without cpu_index by just enabling already preset defaults
in possible_cpus.
PS:
as bonus it makes one less user of cpu_index_to_instance_props()

This simplifies removing a backend for a frontend user (no need to
retrieve the associated driver and separate delete call etc).
NB: many frontends have questionable handling of ending a chardev. They
should probably delete the backend to prevent broken reusage.
