x86_cpu_dump_local_apic_state() is called from monitor.c which
is only compiled for system emulation since commit bf95728400
("monitor: remove target-specific code from monitor.c").
Interestingly this stub was added few weeks later in commit
1f871d49e3 ("hmp: added local apic dump state") and was not
necessary by that time.

The new CPU model mostly inherits features from Icelake-Server, while
adding new features:
- AMX (Advance Matrix eXtensions)
- Bus Lock Debug Exception
and new instructions:
- AVX VNNI (Vector Neural Network Instruction):
- VPDPBUS: Multiply and Add Unsigned and Signed Bytes
- VPDPBUSDS: Multiply and Add Unsigned and Signed Bytes with Saturation
- VPDPWSSD: Multiply and Add Signed Word Integers
- VPDPWSSDS: Multiply and Add Signed Integers with Saturation
- FP16: Replicates existing AVX512 computational SP (FP32) instructions
using FP16 instead of FP32 for ~2X performance gain
- SERIALIZE: Provide software with a simple way to force the processor to
complete all modifications, faster, allowed in all privilege levels and
not causing an unconditional VM exit
- TSX Suspend Load Address Tracking: Allows programmers to choose which
memory accesses do not need to be tracked in the TSX read set
- AVX512_BF16: Vector Neural Network Instructions supporting BFLOAT16
inputs and conversion instructions from IEEE single precision
- fast zero-length MOVSB (KVM doesn't support yet)
- fast short STOSB (KVM doesn't support yet)
- fast short CMPSB, SCASB (KVM doesn't support yet)
Features that may be added in future versions:
- CET (virtualization support hasn't been merged)

At the moment, we look for just "python3" and "python", which is good
enough almost all of the time. But ... if you are on a platform that
uses an older Python by default and only offers a newer Python as an
option, you'll have to specify --python=/usr/bin/foo every time.
We can be kind and instead make a cursory attempt to locate a suitable
Python binary ourselves, looking for the remaining well-known binaries.
This configure loop will prefer, in order:
1. Whatever is specified in $PYTHON
2. python3
3. python
4. python3.11 down through python3.6
Notes:
- Python virtual environment provides binaries for "python3", "python",
and whichever version you used to create the venv,
e.g. "python3.8". If configure is invoked from inside of a venv, this
configure loop will not "break out" of that venv unless that venv is
created using an explicitly non-suitable version of Python that we
cannot use.
- In the event that no suitable python is found, the first python found
is the version used to generate the human-readable error message.
- The error message isn't printed right away to allow later
configuration code to pick up an explicitly configured python.

If neither --python nor --meson are specified, Meson's generated
build.ninja will invoke Python script using the interpreter *that Meson
itself is running under*; not the one identified by configure.
This is only an issue if Meson's Python interpreter is not "the first
one in the path", which is the one that is used if --python is not
specified. A common case where this happen is when the "python3" binary
comes from a virtual environment but Meson is not installed (with pip)
in the virtual environment. In this case (presumably) whoever set up
the venv wanted to use the venv's Python interpreter to build QEMU,
while Meson might use a different one, for example an enterprise
distro's older runtime.
So, detect whether a virtual environment is setup, and if the virtual
environment does not have Meson, use the meson submodule. Meson will
then run under the virtual environment's Python interpreter.

Once upon a time, "sphinx-build" on certain RPM platforms invoked
specifically a Python 2.x version, while "sphinx-build-3" was a distro
shim for the Python 3.x version.
These days, none of our supported platforms utilize a 2.x version, and
those that still have 'sphinx-build-3' make it a symbolic link to
'sphinx-build'. Not searching for 'sphinx-build-3' will prefer
pip/venv installed versions of sphinx if they're available.
This adds an extremely convenient ability to test document building
ability in QEMU across multiple versions of Sphinx for the purposes of
compatibility testing.
