cf7f61d13f target/s390: Convert CPU to Resettable interface
Convert the s390 CPU to the Resettable interface.  This is slightly
more involved than the other CPU types were (see commits
9130cade5fc22..d66e64dd006df) because S390 has its own set of
different kinds of reset with different behaviours that it needs to
trigger.

We handle this by adding these reset types to the Resettable
ResetType enum.  Now instead of having an underlying implementation
of reset that is s390-specific and which might be called either
directly or via the DeviceClass::reset method, we can implement only
the Resettable hold phase method, and have the places that need to
trigger an s390-specific reset type do so by calling
resettable_reset().

The other option would have been to smuggle in the s390 reset
type via, for instance, a field in the CPU state that we set
in s390_do_cpu_initial_reset() etc and then examined in the
reset method, but doing it this way seems cleaner.

The motivation for this change is that this is the last caller
of the legacy device_class_set_parent_reset() function, and
removing that will let us clean up some glue code that we added
for the transition to three-phase reset.

cb771ac1f5 meson: Split --enable-sanitizers to --enable-{asan, ubsan}
We do not always want both address and undefined behavior
sanitizers running at the same time.

For the gitlab custom-runners, drop to only --enable-ubsan.
These jobs are not run by default, but as will be obvious in the
next patch, we don't run ASan on x86 either, and it seems wrong
to hold aarch64 and s390x to a different standard.

The avocado_qemu.Test class has been renamed a while back in commit
2283b627bc ("tests/avocado: Rename avocado_qemu.Test -> QemuSystemTest"),
so we should reflect this now in the documentation, too.

43e0d14ee0 docs/sphinx: fix extra stuff in TOC after freeform QMP sections
Freeform sections with titles are currently generating a TOC entry for
the first paragraph in the section after the header, which is not what
we want.

(Easiest to observe directly in the QMP reference manual's
"Introduction" section.)

When freeform sections are parsed, we create both a section header *and*
an empty, title-less section. This causes some problems with sphinx's
post-parse tree transforms, see also 2664f317 - this is a similar issue:
Sphinx doesn't like section-less titles and it also doesn't like
title-less sections.

Modify qapidoc.py to parse text directly into the preceding section
title as child nodes, eliminating the section duplication. This removes
the extra text from the TOC.

Only very, very lightly tested: "it looks right at a glance" ™️. I am
still in the process of rewriting qapidoc, so I didn't give it much
deeper thought.

48e5b5f994 docs/sphinx/depfile.py: Handle env.doc2path() returning a Path not a str
In newer versions of Sphinx the env.doc2path() API is going to change
to return a Path object rather than a str. This was originally visible
in Sphinx 8.0.0rc1, but has been rolled back for the final 8.0.0
release. However it will probably emit a deprecation warning and is
likely to change for good in 9.0:
  https://github.com/sphinx-doc/sphinx/issues/12686

Our use in depfile.py assumes a str, and if it is passed a Path
it will fall over:
 Handler <function write_depfile at 0x77a1775ff560> for event 'build-finished' threw an exception (exception: unsupported operand type(s) for +: 'PosixPath' and 'str')

Wrapping the env.doc2path() call in str() will coerce a Path object
to the str we expect, and have no effect in older Sphinx versions
that do return a str.

the "Example" section is not valid anymore.
It has been replaced by the "qmp-example" directive.

This was not detected earlier as firmware.json was not validated.
As this validation is about to be added, adapt firmware.json.

06f1f4958b hw/acpi: Update ACPI GED framework to support vCPU Hotplug
ACPI GED (as described in the ACPI 6.4 spec) uses an interrupt listed in the
_CRS object of GED to intimate OSPM about an event. Later then demultiplexes the
notified event by evaluating ACPI _EVT method to know the type of event. Use
ACPI GED to also notify the guest kernel about any CPU hot(un)plug events.

Note, GED interface is used by many hotplug events like memory hotplug, NVDIMM
hotplug and non-hotplug events like system power down event. Each of these can
be selected using a bit in the 32 bit GED IO interface. A bit has been reserved
for the CPU hotplug event.

ACPI CPU hotplug related initialization should only happen if ACPI_CPU_HOTPLUG
support has been enabled for particular architecture. Add cpu_hotplug_hw_init()
stub to avoid compilation break.

0418f90809 Add support for RAPL MSRs in KVM/Qemu
Starting with the "Sandy Bridge" generation, Intel CPUs provide a RAPL
interface (Running Average Power Limit) for advertising the accumulated
energy consumption of various power domains (e.g. CPU packages, DRAM,
etc.).

The consumption is reported via MSRs (model specific registers) like
MSR_PKG_ENERGY_STATUS for the CPU package power domain. These MSRs are
64 bits registers that represent the accumulated energy consumption in
micro Joules. They are updated by microcode every ~1ms.

For now, KVM always returns 0 when the guest requests the value of
these MSRs. Use the KVM MSR filtering mechanism to allow QEMU handle
these MSRs dynamically in userspace.

To limit the amount of system calls for every MSR call, create a new
thread in QEMU that updates the "virtual" MSR values asynchronously.

Each vCPU has its own vMSR to reflect the independence of vCPUs. The
thread updates the vMSR values with the ratio of energy consumed of
the whole physical CPU package the vCPU thread runs on and the
thread's utime and stime values.

All other non-vCPU threads are also taken into account. Their energy
consumption is evenly distributed among all vCPUs threads running on
the same physical CPU package.

To overcome the problem that reading the RAPL MSR requires priviliged
access, a socket communication between QEMU and the qemu-vmsr-helper is
mandatory. You can specified the socket path in the parameter.

This feature is activated with -accel kvm,rapl=true,path=/path/sock.sock

Actual limitation:
- Works only on Intel host CPU because AMD CPUs are using different MSR
  adresses.

- Only the Package Power-Plane (MSR_PKG_ENERGY_STATUS) is reported at
  the moment.

84369d7621 tools: build qemu-vmsr-helper
Introduce a privileged helper to access RAPL MSR.

The privileged helper tool, qemu-vmsr-helper, is designed to provide
virtual machines with the ability to read specific RAPL (Running Average
Power Limit) MSRs without requiring CAP_SYS_RAWIO privileges or relying
on external, out-of-tree patches.

The helper tool leverages Unix permissions and SO_PEERCRED socket
options to enforce access control, ensuring that only processes
explicitly requesting read access via readmsr() from a valid Thread ID
can access these MSRs.

The list of RAPL MSRs that are allowed to be read by the helper tool is
defined in rapl-msr-index.h. This list corresponds to the RAPL MSRs that
will be supported in the next commit titled "Add support for RAPL MSRs
in KVM/QEMU."

The tool is intentionally designed to run on the Linux x86 platform.
This initial implementation is tailored for Intel CPUs but can be
extended to support AMD CPUs in the future.

58fc249d9e plugins/stoptrigger: TCG plugin to stop execution under conditions
This new plugin allows to stop emulation using conditions on the
emulation state. By setting this plugin arguments, it is possible
to set an instruction count limit and/or trigger address(es) to stop at.
The code returned at emulation exit can be customized.

This plugin demonstrates how someone could stop QEMU execution.
It could be used for research purposes to launch some code and
deterministically stop it and understand where its execution flow went.

056b779eaf aspeed: Introduce a 'boot-emmc' machine option
The default behavior of some Aspeed machines is to boot from the eMMC
device, like the rainier-bmc. Others like ast2600-evb could also boot
from eMMC if the HW strapping boot-from-eMMC bit was set. Add a
property to set or unset this bit. This is useful to test boot images.

For now, only activate this property on the ast2600-evb and rainier-bmc
machines for which eMMC images are available or can be built.

ce22616181 guest-agent: document allow-rpcs in config file section
While the `allow-rpcs` option is documented in the CLI options
section, it was missing in the section about the configuration file
syntax.

And while it's mentioned that "the list of keys follows the command line
options", having `block-rpcs` there but not `allow-rpcs` seems like
being a potential source of confusion; and as it's cheap to add let's
just do so.
