vmstate_acpi_pcihp_use_acpi_index() was expecting AcpiPciHpState
as state but it actually received PIIX4PMState, because
VMSTATE_PCI_HOTPLUG is a macro and not another struct.
So it ended up accessing random pointer, which resulted
in 'false' return value and acpi_index field wasn't ever
sent.
However in 7.0 that pointer de-references to value > 0, and
destination QEMU starts to expect the field which isn't
sent in migratioon stream from older QEMU (6.2 and older).
As result migration fails with:
qemu-system-x86_64: Missing section footer for 0000:00:01.3/piix4_pm
qemu-system-x86_64: load of migration failed: Invalid argument
In addition with QEMU-6.2, destination due to not expected
state, also never expects the acpi_index field in migration
stream.
Q35 is not affected as it always sends/expects the field as
long as acpi based PCI hotplug is enabled.
Fix issue by introducing compat knob to never send/expect
acpi_index in migration stream for 6.2 and older PC machine
types and always send it for 7.0 and newer PC machine types.

The spec defines 3 registers, even though only index 0 and 2 are valid
on POWER9. The same model is used on POWER10. Register 1 is defined
there but we currently don't use it in skiboot. So we can keep
reporting an error on write.

The timebase is allocated during spapr_realize_vcpu() and it's not

These assertions are very useful for developers to find bugs, and so
they have indeed pointed us towards bugs already. For users, it is not
so useful to find these bugs. We should probably not enable them in
releases until we are sufficiently certain that they will not fire
during normal operation, unless something is going seriously wrong.
For example, we have received a bug report that you cannot add an NBD
server on a BDS in an I/O thread with `-incoming defer`. I am sure this
is a real bug that needs investigation, but we do not really have that
time right now, so close to release, and so I would rather disable the
assertions to get time to investigate such reports.
(I am just putting the link as "buglink" below, not "closes", because
disabling the assertion will not fix the likely underlying bug.)

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

On older Solaris releases (before Solaris 11), we didn't get a
prototype for madvise, and so util/osdep.c provides its own prototype.
Some time between the public Solaris 11.4 release and Solaris 11.4.42
CBE, we started getting an madvise prototype that looks like this:
extern int madvise(void *, size_t, int);
which conflicts with the prototype in util/osdeps.c. Instead of always
declaring this prototype, check if we're missing the madvise()
prototype, and only declare it ourselves if the prototype is missing.
Move the prototype to include/qemu/osdep.h, the normal place to handle
platform-specific header quirks.
The 'missing_madvise_proto' meson check contains an obviously wrong
prototype for madvise. So if that code compiles and links, we must be
missing the actual prototype for madvise.

This patch lets callers invoke the kvm_irqchip_commit_routes(), so the

The DBus listener naively create, update and destroy textures without
taking into account other listeners. The texture were shared, but
texture update was unnecessarily duplicated.
Teach DisplayGLCtx to do optionally shared texture handling. This is
only implemented for DBus display at this point, however the same
infrastructure could potentially be used for other future combinations.

SVQ is able to log the dirty bits by itself, so let's use it to not
block migration.
Also, ignore set and clear of VHOST_F_LOG_ALL on set_features if SVQ is
enabled. Even if the device supports it, the reports would be nonsense
because SVQ memory is in the qemu region.
The log region is still allocated. Future changes might skip that, but

On a real system with POWER{8,9,10} processors, PHBs are sub-units of
the processor, they can be deactivated by firmware but not plugged in
or out like a PCI adapter on a slot. Nevertheless, having user-created
PHBs in QEMU seemed to be a good idea for testing purposes :
1. having a limited set of PHBs speedups boot time.
2. it is useful to be able to mimic a partially broken topology you
some time have to deal with during bring-up.
PowerNV is also used for distro install tests and having libvirt
support eases these tasks. libvirt prefers to run the machine with
-nodefaults to be sure not to drag unexpected devices which would need
to be defined in the domain file without being specified on the QEMU
command line. For this reason :
3. -nodefaults should not include default PHBs
User-created PHB{3,4,5} devices satisfied all these needs but reality
proves to be a bit more complex, internally when modeling such
devices, and externally when dealing with the user interface.
Req 1. and 2. can be simply addressed differently with a machine option:
"phb-mask=<uint>", which QEMU would use to enable/disable PHB device
nodes when creating the device tree.
For Req 3., we need to make sure we are taking the right approach. It
seems that we should expose a new type of user-created PHB device, a
generic virtualized one, that libvirt would use and not one depending
on the processor revision. This needs more thinking.
For now, remove user-created PHB{3,4,5} devices. All the cleanups we
did are not lost and they will be useful for the next steps.

We already have the pnv-phb3 and pnv-phb4 devices for POWER8 and
POWER9 respectively. POWER10 uses version 5 of the PHB. It is very
close to the PHB4 from POWER9, at least in our model and we could
almost keep using the PHB4 model. However the matching root port
pnv-phb5-root-port is specific to POWER10 so to avoid confusion as
well as making it easy to introduce differences later, we create a
pnv-phb5 class, which is mostly an alias for pnv-phb4 for now.
With this patch, the command line for a user-created PHB on powernv10
becomes:
-machine powernv10 -nodefaults -device pnv-phb5 -device pnv-phb5-root-port

The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 during
initialisation and resolution changes. Whilst the function of many of these
registers is unknown, it is worth the minimal cost of saving these extra values as
part of migration to help future-proof the migration stream for the q800 machine
as it starts to stabilise.
Note this is a migration break, but since there are upcoming incompatible changes
for the q800 machine (and migration does not even succeed without these patches)
then this is not an issue.

The mos6522 datasheet describes how the control lines IRQs are edge-triggered
according to the configuration in the PCR register. Implement the logic according
to the datasheet so that the interrupt bits in IFR are latched when the edge is
detected, and cleared when reading portA/portB or writing to IFR as necessary.
To maintain bisectibility this change also updates the SCSI, SCSI data, Nubus
and VIA2 60Hz/1Hz clocks in the q800 machine to be negative edge-triggered as
confirmed by the PCR programming in all of Linux, NetBSD and MacOS.
