A recent change in spapr_machine_reset() showed that resetting the compat
mode in spapr_machine_reset() for the boot vCPU and in spapr_cpu_reset()
for all other vCPUs was fragile. The fix was thus to reset the compat mode
for all vCPUs in spapr_machine_reset(), but we still have to propagate
it to hot-plugged CPUs. This is still performed from spapr_cpu_reset(),
hence resulting in ppc_set_compat() being called twice for every vCPU at
machine reset. Apart from wasting cycles, which isn't really an issue
during machine reset, this seems to indicate that spapr_cpu_reset() isn't
the best place to set the compat mode.
A natural candidate for CPU-hotplug specific code is spapr_core_plug().
Also, it sits in the same file as spapr_machine_reset() : this makes
it easier for someone who wants to know when the compat PVR is set.
Call ppc_set_compat() from there. This doesn't need to be done for
initial vCPUs since the compat PVR is 0 and spapr_machine_reset() sets
the appropriate value later. No need to do this on manually added vCPUS
on the destination QEMU during migration since the compat PVR is
part of the migrated vCPU state. Both conditions can be checked with
spapr_drc_hotplugged().

The pseries guests do not normally allocate PCI resources and rely on
the system firmware doing so. Furthermore at least at some point in
the past the pseries guests won't even allowed to change BARs, probably
it is still the case for phyp. So since the initial commit we have [1]
which prevents resource reallocation.
This is not a problem until we want specific BAR alignments, for example,
PAGE_SIZE==64k to make sure we can still map MMIO BARs directly. For
the boot time devices we handle this in SLOF [2] but since QEMU's RTAS
does not allocate BARs, the guest does this instead and does not align
BARs even if Linux is given pci=resource_alignment=16@pci:0:0 as
PCI_PROBE_ONLY makes Linux ignore alignment requests.
ARM folks added a dial to control PCI_PROBE_ONLY via the device tree [3].
This makes use of the dial to advertise to the guest that we can handle
BAR reassignments. This limits the change to the latest pseries machine
to avoid old guests explosion.
We do not remove the flag from [1] as pseries guests are still supported
under phyp so having that removed may cause problems.

The sPAPR platform includes feature negotiation between the guest and
platform. That sometimes requires reconfiguring the virtual hardware, and
in some cases that is a complex enough process that we trigger a system
reset to handle it. That interacts badly with -no-reboot - we trigger the
reboot, -no-reboot means we exit and so the guest never gets to try again.
Eventually we want to get rid of CAS reboots entirely, since they're odd
and irritating for the user. But in the meantime we can fix the -no-reboot
problem by using SHUTDOWN_CAUSE_SUBSYSTEM_RESET which ignores -no-reboot
and seems to be designed for this sort of faux-reset for internal purposes
only.

The ibm,get_system_parameter rtas call is used by the guest to retrieve
data relating to certain parameters of the system. The SPLPAR
characteristics option (token 20) is used to determine characteristics of
the environment in which the lpar will run.
It may be useful for a guest to know the number of physical host threads
present on the underlying system where it is being run. Add the
characteristic "HostThrs" to the SPLPAR Characteristics
ibm,get_system_parameter rtas call to expose this information to a
guest. Add a n_host_threads property to the processor class which is
then used to retrieve this information and define it for POWER8 and
POWER9. Other processors will default to 0 and the charateristic won't
be added.

If we a migrate P8 machine to a P9 machine, the migration fails on
destination with:
error while loading state for instance 0x1 of device 'cpu'
load of migration failed: Operation not permitted
This is caused because the compat_pvr field is only present for the first
CPU.
Originally, spapr_machine_reset() calls ppc_set_compat() to set the value
max_compat_pvr for the first cpu and this was propagated to all CPUs by
spapr_cpu_reset(). Now, as spapr_cpu_reset() is called before that, the
value is not propagated to all CPUs and the migration fails.
To fix that, propagate the new value to all CPUs in spapr_machine_reset().

There is nothing wrong with how sPAPR handles multifunction PCI
hot unplugs. The problem is that x86 does it simpler. Instead of
removing each non-zero function and then removing function zero,
x86 can remove any function of the slot to trigger the hot unplug.
Libvirt will be directly impacted by this difference, in the
(hopefully soon) PCI Multifunction hot plug/unplug support. For
hot plugs, both x86 and sPAPR will operate the same way: a XML
with all desired functions to be added, then consecutive hotplugs
of all non-zero functions first, zero last. For hot unplugs, at
least in the current state, a XML with the devices to be removed
must also be provided because of how sPAPR operates - x86 does
not need it - since any function unplug will unplug the whole
PCIe slot. This difference puts extra strain in the management
layer, which needs to either handle both archs differently in
the unplug scenario or choose treat x86 like sPAPR, forcing x86
users to cope with sPAPR internals.
This patch changes spapr_pci_unplug_request to handle the
unplug of function zero differently. When removing function zero,
instead of error-ing out if there are any remaining function
DRCs which needs detaching, detach those. This has no effect in
any existing scripts that are detaching the non-zero functions
before function zero, and can be used by management as a shortcut
to remove the whole PCI multifunction device without specifying
each child function.

However, alsa has three fields in per direction options: a string, an

Handling of the 'F' packet has been broken since commit
4b20fab101, which converted it to use
the new packet parsing infrastructure. Per the GDB RSP specification
https://sourceware.org/gdb/current/onlinedocs/gdb/The-F-Reply-Packet.html
the second parameter may be omitted, but the rewritten implementation
was failing to recognize this case. The result was that QEMU was
repeatedly resending the fileio request and ignoring GDB's replies of
successful completion. This patch restores the behavior of the
previous code in allowing the errno parameter to be omitted and
passing 0 to the callback in that case.

Since the '!' packet is not handled by the new infrastructure,
gdb_handle_packet() would call run_cmd_parser() with a NULL cmd_parser
value, which would lead to an unsupported packet ("$#00") being sent,
which could confuse the gdb client.
This also has a side-effect of speeding up the initial connection with
gdb.

The current approach to capture the Python version is fragile, as it
was demonstrated by a very specific build of Python 3 on Fedora 29
that, under non-interactive shells would print multiline version
information.
The (badly) stripped version output would be sent to config-host.mak,
producing bad syntax and rendering the makefiles unusable. Now, the
Python versions is printed by configure, but only a simple (and better
controlled variable) indicating whether the build system is using
Python 2 is kept on config-host.mak.

In commit f6e501a28e, Eduardo started to use "check_" as a
prefix for methods of similar purpose. Follow this prior art,
since it might become the conventions when writting Avocado
tests.

Most tracing backends are implemented within QEMU, except the
DTrace/SystemTap backends.
One side effect is when running 'qemu -trace help', an incomplete
list of trace events is displayed when using the DTrace/SystemTap
backends.
This is partly due to trace events registered as modules with
trace_init(), and since the events are not used within QEMU,
the linker optimize and remove the unused modules (which is
OK in this particular case).
Currently only the events compiled in trace-root.o and in the
last trace.o member of libqemuutil.a are linked, resulting in
an incomplete list of events.
To avoid confusion, improve the help message, recommending to
use the proper systemtap script to display the events list.
Before:
$ lm32-softmmu/qemu-system-lm32 -trace help 2>&1 | wc -l
70
After:
$ lm32-softmmu/qemu-system-lm32 -trace help
Run 'qemu-trace-stap list qemu-system-lm32' to print a list
of names of trace points with the DTrace/SystemTap backends.
$ qemu-trace-stap list qemu-system-lm32 | wc -l
1136
