The spapr_phb_realize() function has a local_err variable which
is used to:
1) check failures of spapr_irq_findone() and spapr_irq_claim()
2) prepend extra information to the error message
Recent work from Markus Armbruster highlighted we get better
code when testing the return value of a function, rather than
setting up all the local_err boiler plate. For similar reasons,
it is now preferred to use ERRP_GUARD() and error_prepend()
rather than error_propagate_prepend().
Since spapr_irq_findone() and spapr_irq_claim() return negative
values in case of failure, do both changes.
This is just cleanup, no functional impact.

Calls to the KVM XIVE device are guarded by kvm_irqchip_in_kernel(). This
ensures that QEMU won't try to use the device if KVM is disabled or if
an in-kernel irqchip isn't required.
When using ic-mode=dual with the pseries machine, we have two possible
interrupt controllers: XIVE and XICS. The kvm_irqchip_in_kernel() helper
will return true as soon as any of the KVM device is created. It might
lure QEMU to think that the other one is also around, while it is not.
This is exactly what happens with ic-mode=dual at machine init when
claiming IRQ numbers, which must be done on all possible IRQ backends,
eg. RTAS event sources or the PHB0 LSI table : only the KVM XICS device
is active but we end up calling kvmppc_xive_source_reset_one() anyway,
which fails. This doesn't cause any trouble because of another bug :
kvmppc_xive_source_reset_one() lacks an error_setg() and callers don't
see the failure.
Most of the other kvmppc_xive_* functions have similar xive->fd
checks to filter out the case when KVM XIVE isn't active. It
might look safer to have idempotent functions but it doesn't
really help to understand what's going on when debugging.
Since we already have all the kvm_irqchip_in_kernel() in place,
also have the callers to check xive->fd as well before calling
KVM XIVE specific code. This is straight-forward for the spapr
specific XIVE code. Some more care is needed for the platform
agnostic XIVE code since it cannot access xive->fd directly.
Introduce new in_kernel() methods in some base XIVE classes
for this purpose and implement them only in spapr.
In all cases, we still need to call kvm_irqchip_in_kernel() so that
compilers can optimize the kvmppc_xive_* calls away when CONFIG_KVM
isn't defined, thus avoiding the need for stubs.

Depending on whether XIVE is emultated or backed with a KVM XIVE device,
the ESB MMIOs of a XIVE source point to an I/O memory region or a mapped
memory region.
This is currently handled by checking kvm_irqchip_in_kernel() returns
false in xive_source_realize(). This is a bit awkward as we usually
need to do extra things when we're using the in-kernel backend, not
less. But most important, we can do better: turn the existing "xive.esb"
memory region into a plain container, introduce an "xive.esb-emulated"
I/O subregion and rename the existing "xive.esb" subregion in the KVM
code to "xive.esb-kvm". Since "xive.esb-kvm" is added with overlap
and a higher priority, it prevails over "xive.esb-emulated" (ie.
a guest using KVM XIVE will interact with "xive.esb-kvm" instead of
the default "xive.esb-emulated" region.
While here, consolidate the computation of the MMIO region size in
a common helper.

When starting an L2 KVM guest with `ic-mode=dual,kernel-irqchip=on`,
QEMU fails with:
KVM is too old to support ic-mode=dual,kernel-irqchip=on
This error message was introduced to detect older KVM versions that
didn't allow destruction and re-creation of the XICS KVM device that
we do at reboot. But it is actually the same issue that we get with
nested guests : when running under pseries, KVM currently provides
a genuine XICS device (not the XICS-on-XIVE device that we get
under powernv) which doesn't support destruction/re-creation.
This will eventually be fixed in KVM but in the meantime, update
the error message and documentation to mention the nested case.
While here, mention that in "No XIVE support in KVM" section that
this can also happen with "guest OSes supporting XIVE" since
we check this at init time before starting the guest.

This patch fixes the behavior of some evfs* instructions that were
incorrectly emitting the interrupt.
More importantly, this patch fixes the behavior of several efd* and ev*
instructions that were not generating the interrupt. Triggering the
interrupt for these instructions fixes lazy FPU/vector context switching on
some operating systems like Linux.
Without this patch, the result of some double-precision arithmetic could be
corrupted due to the lack of proper saving and restoring of the upper
32-bit part of the general-purpose registers.

When a coprocessor instruction in an AArch32 guest traps to AArch32
Hyp mode, the syndrome register (HSR) includes Rt and Rt2 fields
which are simply copies of the Rt and Rt2 fields from the trapped
instruction. However, if the instruction is trapped from AArch32 to
an AArch64 higher exception level, the Rt and Rt2 fields in the
syndrome register (ESR_ELx) must be the AArch64 view of the register.
This makes a difference if the AArch32 guest was in a mode other than
User or System and it was using r13 or r14, or if it was in FIQ mode
and using r8-r14.
We don't know at translate time which AArch32 CPU mode we are in, so
we leave the values we generate in our prototype syndrome register
value at translate time as the raw Rt/Rt2 from the instruction, and
instead correct them to the AArch64 view when we find we need to take
an exception from AArch32 to AArch64 with one of these syndrome
values.

Without python3-venv, I get the following message when trying to
run the acceptance tests within the debian container:
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.
Let's do it as the message suggests.
And while we're at it, also add netcat here since it is required for
some of the acceptance tests.

This likely affects other, less popular host architectures as well.
Less common host architectures under linux get QEMU_VMALLOC_ALIGN (from
which VIRTIO_MEM_MIN_BLOCK_SIZE is derived) define to a variable of
type uintptr, which isn't compatible with the format specifier used to
print a user message. Since this particular usage of the underlying data
seems unique to this file, the simple fix is to just cast
QEMU_VMALLOC_ALIGN to uint32_t, which corresponds to the format specifier
used.
