To solve issues [1-2] the Hot Plug Capable bit in PCIe Slots will be
turned on, while the switch to ACPI Hot-plug will be done in the
DSDT table.
Introducing 'x-keep-native-hpc' property disables the HPC bit only
in 6.1 and as a result keeps the forced 'reserve-io' on
pcie-root-ports in 6.1 too.

Mark property as experimental/internal adding 'x-' prefix.
Property was introduced in 6.1 and it should have provided
ability to turn on native PCIE hotplug on port even when
ACPI PCI hotplug is in use is user explicitly sets property
on CLI. However that never worked since slot is wired to
ACPI hotplug controller.
Another non-intended usecase: disable native hotplug on slot
when APCI based hotplug is disabled, which works but slot has
'hotplug' property for this taks.
It should be relatively safe to rename it to experimental
as no users should exist for it and given that the property
is broken we don't really want to leave it around for much
longer lest users start using it.

In the real SMP hardware topology world, it's much more likely that
we have high cores-per-socket counts and few sockets totally. While
the current preference of sockets over cores in smp parsing results
in a virtual cpu topology with low cores-per-sockets counts and a
large number of sockets, which is just contrary to the real world.
Given that it is better to make the virtual cpu topology be more
reflective of the real world and also for the sake of compatibility,
we start to prefer cores over sockets over threads in smp parsing
since machine type 6.2 for different arches.
In this patch, a boolean "smp_prefer_sockets" is added, and we only
enable the old preference on older machines and enable the new one
since type 6.2 for all arches by using the machine compat mechanism.

QEMU's kvmclock device is only created when KVM PV feature bits for
kvmclock (KVM_FEATURE_CLOCKSOURCE/KVM_FEATURE_CLOCKSOURCE2) are
exposed to the guest. With 'kvm=off' cpu flag the device is not
created and we don't call KVM_GET_CLOCK/KVM_SET_CLOCK upon migration.
It was reported that without these call at least Hyper-V TSC page
clocksouce (which can be enabled independently) gets broken after
migration.
Switch to creating kvmclock QEMU device unconditionally, it seems
to always make sense to call KVM_GET_CLOCK/KVM_SET_CLOCK on migration.

Let's auto-enable it also when maxmem is specified but no slots are
defined. This will result in us properly creating ACPI srat tables,
indicating the maximum possible PFN to the guest OS. Based on this, e.g.,
Linux will enable the swiotlb properly.
This avoids having to manually force the switolb on (swiotlb=force) in
Linux in case we're booting only using DMA memory (e.g., 2GB on x86-64),
and virtio-mem adds memory later on that really needs the swiotlb to be
used for DMA.
Let's take care of backwards compatibility if somebody has a setup that
specifies "maxram" without "slots".

The only way object_property_add() can fail is when a property with
the same name already exists. Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.
Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent. Parentage is
also under program control, so this is a programming error, too.
We have a bit over 500 callers. Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.
The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.
Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call. ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.
When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.
Drop parameter @errp and assert the preconditions instead.
There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification". Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

5.0 machine type uses 4.2 compats. This seems to be incorrect, since
the latests machine type by now is 5.0 and it should use its own
compat or shouldn't use any relying on the defaults.
Seems, like this appeared because of some problems on merge/rebase.

Add 5.0 machine types for arm/i440fx/q35/s390x/spapr.
For i440fx and q35, unversioned cpu models are still translated
to -v1; I'll leave changing this (if desired) to the respective
maintainers.

Virtio spec 1.1 (and earlier), 5.2.5.2 Driver Requirements: Device
Initialization:
"Devices SHOULD always offer VIRTIO_BLK_F_FLUSH, and MUST offer it if
they offer VIRTIO_BLK_F_CONFIG_WCE"
Currently F_CONFIG_WCE and F_WCE are not connected to each other.
Qemu will advertise F_CONFIG_WCE if config-wce argument is
set for virtio-blk device. And F_WCE is advertised only if
underlying block backend actually has it's caching enabled.
Fix this by advertising F_WCE if F_CONFIG_WCE is also advertised.
To preserve backwards compatibility with newer machine types make this
behaviour governed by "x-enable-wce-if-config-wce" virtio-blk-device
property and introduce hw_compat_4_2 with new property being off by
default for all machine types <= 4.2 (but don't introduce 4.3
machine type itself yet).

Attempting to migrate a VM using the microvm machine class results in the source
QEMU aborting with the following message/backtrace:
target/i386/machine.c:955:tsc_khz_needed: Object 0x555556608fa0 is not an
instance of type generic-pc-machine
abort()
object_class_dynamic_cast_assert()

vmstate_save()
qemu_savevm_state_complete_precopy()
migration_thread()
migration_thread()
migration_thread()
qemu_thread_start()
start_thread()
clone()
The access to the machine class returned by MACHINE_GET_CLASS() in
tsc_khz_needed() is crashing as it is trying to dereference a different
type of machine class object (TYPE_PC_MACHINE) to that of this microVM.
This can be resolved by extending the changes in the following commit
f0bb276bf8 ("hw/i386: split PCMachineState deriving X86MachineState from it")
and moving the save_tsc_khz field in PCMachineClass to X86MachineClass.

Move it out of pc.c since it is strictly tied to TCG. This is
almost exclusively code movement, the next patch will implement
