target/i386: add support for FLUSH_L1D feature
As reported by Intel's doc:
"L1D_FLUSH: Writeback and invalidate the L1 data cache"
If this cpu feature is present in host, allow QEMU to choose whether to
show it to the guest too.
One disadvantage of not exposing it is that the guest will report
a non existing vulnerability in
/sys/devices/system/cpu/vulnerabilities/mmio_stale_data
because the mitigation is present only when the cpu has
(FLUSH_L1D and MD_CLEAR) or FB_CLEAR
features enabled.

target/i386: fix operand size for VCOMI/VUCOMI instructions
Compared to other SSE instructions, VUCOMISx and VCOMISx are different:
the single and double precision versions are distinguished through a
prefix, however they use no-prefix and 0x66 for SS and SD respectively.
Scalar values usually are associated with 0xF2 and 0xF3.
Because of these, they incorrectly perform a 128-bit memory load instead
of a 32- or 64-bit load. Fix this by writing a custom decoding function.
I tested that the reproducer is fixed and the test-avx output does not
change.

target/i386: Fix exception classes for SSE/AVX instructions.
Fix the exception classes for some SSE/AVX instructions to match what is
documented in the Intel manual.
These changes are expected to have no functional effect on the behavior
that qemu implements (primarily >= 16-byte memory alignment checks). For
instance, since qemu does not implement the AC flag, there is no
difference in behavior between Exception Classes 4 and 5 for
instructions where the SSE version only takes <16 byte memory operands.

meson: Pass -j option to sphinx
Save a bit of build time by passing the number of jobs option to
sphinx.
We cannot use the -j option from make because meson does not support
setting build time parameters for custom targets. Use nproc instead or
the equivalent sphinx option "-j auto", if that is available (version
>=1.7.0).
Also make sure our plugins support parallelism and report it properly
to sphinx. Particularly, implement the merge_domaindata method in
DBusDomain that is used to merge in data from other subprocesses.

migration: Add last stage indicator to global dirty log
The global dirty log synchronization is used when KVM and dirty ring
are enabled. There is a particularity for ARM64 where the backup
bitmap is used to track dirty pages in non-running-vcpu situations.
It means the dirty ring works with the combination of ring buffer
and backup bitmap. The dirty bits in the backup bitmap needs to
collected in the last stage of live migration.
In order to identify the last stage of live migration and pass it
down, an extra parameter is added to the relevant functions and
callbacks. This last stage indicator isn't used until the dirty
ring is enabled in the subsequent patches.
No functional change intended.

kvm: Enable dirty ring for arm64
arm64 has different capability from x86 to enable the dirty ring, which
is KVM_CAP_DIRTY_LOG_RING_ACQ_REL. Besides, arm64 also needs the backup
bitmap extension (KVM_CAP_DIRTY_LOG_RING_WITH_BITMAP) when 'kvm-arm-gicv3'
or 'arm-its-kvm' device is enabled. Here the extension is always enabled
and the unnecessary overhead to do the last stage of dirty log synchronization
when those two devices aren't used is introduced, but the overhead should
be very small and acceptable. The benefit is cover future cases where those
two devices are used without modifying the code.

Log Message:
-----------
make: clean after distclean deletes source files
Run 'make distclean' in a tree, and GNUmakefile is removed.
But, GNUmakefile is where we change directory to build.
Run 'make distclean' or 'make clean' again, and Makefile applies
the clean actions, such as this one, at the top level of the tree.
For example, it removes the .d source files in 'meson/test cases/d/*/*.d'.
find . \( -name '*.so' -o -name '*.dll' -o \
-name '*.[oda]' -o -name '*.gcno' \) -type f \
! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-aarch64.a \
! -path ./roms/edk2/ArmPkg/Library/GccLto/liblto-arm.a \
-exec rm {} +
To fix, remove clean and distclean from UNCHECKED_GOALS, so those targets
are "checked", meaning that configure must be run before make. However,
the check action does not trigger, because clean does not depend on
config-host.mak, so change the action to simply throw an error.

Recent versions of pip also complain that some of the dependencies in
our virtual environment rely on "setup.py install" instead of providing
a pyproject.toml file; apparently it is deprecated to install them
directly from pip instead of letting the "wheel" package take care
of them. So, install "wheel" in the virtual environment.

python: add mkvenv.py
This script will be responsible for building a lightweight Python
virtual environment at configure time. It works with Python 3.6 or
newer.
It has been designed to:
- work *offline*, no PyPI required.
- work *quickly*, The fast path is only ~65ms on my machine.
- work *robustly*, with multiple fallbacks to keep things working.
- work *cooperatively*, using system packages where possible.
(You can use your distro's meson, no problem.)
Due to its unique position in the build chain, it exists outside of the
installable python packages in-tree and *must* be runnable without any
third party dependencies.
Under normal circumstances, the only dependency required to execute this
script is Python 3.6+ itself. The script is *faster* by several seconds
when setuptools and pip are installed in the host environment, which is
probably the case for a typical multi-purpose developer workstation.
In the event that pip/setuptools are missing or not usable, additional
dependencies may be required on some distributions which remove certain
Python stdlib modules to package them separately:
- Debian may require python3-venv to provide "ensurepip"
- NetBSD may require py310-expat to provide "pyexpat" *
(* Or whichever version is current for NetBSD.)

mkvenv: add nested venv workaround
Python virtual environments do not typically nest; they may inherit from
the top-level system packages or not at all.
For our purposes, it would be convenient to emulate "nested" virtual
environments to allow callers of the configure script to install
specific versions of python utilities in order to test build system

While it is possible to install packages into the system environment
(say, by using the --user flag), it's nicer to install test packages
into a totally isolated environment instead.
As detailed in https://www.qemu.org/2023/03/24/python/, Emulate a nested
venv environment by using .pth files installed into the site-packages
folder that points to the parent environment when appropriate.

mkvenv: add ensure subcommand
This command is to be used to add various packages (or ensure they're
already present) into the configure-provided venv in a modular fashion.
Examples:
mkvenv ensure --online --dir "${source_dir}/python/wheels/" "meson>=0.61.5"
mkvenv ensure --online "sphinx>=1.6.0"
mkvenv ensure "qemu.qmp==0.0.2"
It's designed to look for packages in three places, in order:
(1) In system packages, if the version installed is already good
enough. This way your distribution-provided meson, sphinx, etc are
always used as first preference.
(2) In a vendored packages directory. Here I am suggesting
qemu.git/python/wheels/ as that directory. This is intended to serve as
a replacement for vendoring the meson source for QEMU tarballs. It is
also highly likely to be extremely useful for packaging the "qemu.qmp"
package in source distributions for platforms that do not yet package
qemu.qmp separately.
(3) Online, via PyPI, ***only when "--online" is passed***. This is only
ever used as a fallback if the first two sources do not have an
appropriate package that meets the requirement. The ability to build
QEMU and run tests *completely offline* is not impinged.

mkvenv: add --diagnose option to explain "ensure" failures
This is a routine that is designed to print some usable info for human
beings back out to the terminal if/when "mkvenv ensure" fails to locate
or install a package during configure time, such as meson or sphinx.
Since we are requiring that "meson" and "sphinx" are installed to the
same Python environment as QEMU is configured to build with, this can
produce some surprising failures when things are mismatched. This method
is here to try and ease that sting by offering some actionable
diagnosis.

mkvenv: add console script entry point generation
When creating a virtual environment that inherits system packages,

re-generated with the correct shebang. When you are *inside* of the
venv, this is not a problem, but if you are *outside* of it, you will
not have a script that engages the virtual environment appropriately.
Add a mechanism that generates new entry points for pre-existing
packages so that we can use these scripts to run "meson",
"sphinx-build", "pip", unambiguously inside the venv.

mkvenv: use pip's vendored distlib as a fallback
distlib is usually not installed on Linux distribution, but it is vendored
into pip. Because the virtual environment has pip via ensurepip, we
can piggy-back on pip's vendored version. This could break if they move
our cheese in the future, but the fix would be simply to require distlib.
If it is debundled, as it is on msys, it is simply available directly.

possible that this bug might appear on other derivative platforms and

tests/docker: add python3-venv dependency
Several debian-based tests need the python3-venv dependency as a
consequence of Debian debundling the "ensurepip" module normally
included with Python.
As mkvenv.py stands as of this commit, Debian requires EITHER:
(A) setuptools and pip, or
(B) ensurepip
mkvenv is a few seconds faster if you have setuptools and pip, so
developers should prefer the first requirement. For the purposes of CI,
the time-save is a wash; it's only a matter of who is responsible for
installing pip and when; the timing is about the same.
Arbitrarily, I chose adding ensurepip to the test configuration because
it is normally part of the Python stdlib, and always having it allows us
a more consistent cross-platform environment.

python/wheels: add vendored meson package
In preference to vendoring meson source, vendor a built distributable
("bdist" in python parlance). This has some benefits:
(1) We can get rid of a git submodule,
(2) Installing built meson into a venv doesn't require any extra
dependencies (the python "wheel" package, chiefly.)
(3) We don't treat meson any differently than we would any other python
package (we install it, end of story, done.)
(4) All future tarball *and* developer checkouts will function offline;
No git or PyPI connection needed to fetch meson.
Note that because mkvenv prefers vendored packages to PyPI, as mkvenv is
currently written we will never consult PyPI for meson. (Do keep in mind
that your distribution's meson will be preferred above the vendored
version, though.)

configure: use 'mkvenv ensure meson' to bootstrap meson
This commit changes how we detect and install meson. It notably removes
'--meson='.
Currently, configure creates a lightweight Python virtual environment
unconditionally using the user's configured $python that inherits system
packages. Temporarily, we forced the use of meson source present via git
submodule or in the release tarball.
With this patch, we restore the ability to use a system-provided meson:
If Meson is installed in the build venv and meets our minimum version
requirements, we will use that Meson. This includes a system provided
meson, which would be visible via system-site packages inside the venv.
In the event that Meson is installed but *not for the chosen Python
interpreter*, not found, or of insufficient version, we will attempt to
install Meson from vendored source into the newly created Python virtual
environment. This vendored installation replaces both the git submodule
and tarball source mechanisms for sourcing meson.
As a result of this patch, the Python interpreter we use for both our
own build scripts *and* Meson extensions are always known to be the
exact same Python. As a further benefit, there will also be a symlink
available in the build directory that points to the correct, configured
python and can be used by e.g. manual tests to invoke the correct,
configured Python unambiguously.

configure: add --enable-pypi and --disable-pypi
In the event that there's no vendored source present and no sufficient
version of $package can be found, we will attempt to connect to PyPI to
install the package if '--disable-pypi' was not passed.
This means that PyPI access is "enabled by default", but there are some
subtleties that make this action occur much less frequently than you
might imagine:
(1) While --enable-pypi is the default, vendored source will always be
preferred when found, making PyPI a fallback. This should ensure
that configure-time venv building "just works" for almost everyone
in almost every circumstance.
(2) Because meson source is, at time of writing, vendored directly into
qemu.git, PyPI will never be used for sourcing meson.
(3) Because Sphinx is an optional dependency, if docs are set to "auto",
PyPI will not be used to obtain Sphinx source as a fallback and
instead docs will be disabled. If PyPI sourcing of sphinx is
desired, --enable-docs should be passed to force the lookup. I chose
this as the default behavior to avoid adding new internet lookups to
a "default" invocation of configure.

Python: Drop support for Python 3.6
Python 3.6 was EOL 2021-12-31. Newer versions of upstream libraries have
begun dropping support for this version and it is becoming more
cumbersome to support. Avocado-framework and qemu.qmp each have their
own reasons for wanting to drop Python 3.6, but won't until QEMU does.
Versions of Python available in our supported build platforms as of today,
with optional versions available in parentheses:
openSUSE Leap 15.4: 3.6.15 (3.9.10, 3.10.2)
CentOS Stream 8: 3.6.8 (3.8.13, 3.9.16)
CentOS Stream 9: 3.9.13
Fedora 36: 3.10
Fedora 37: 3.11
Debian 11: 3.9.2
Alpine 3.14, 3.15: 3.9.16
Alpine 3.16, 3.17: 3.10.10
Ubuntu 20.04 LTS: 3.8.10
Ubuntu 22.04 LTS: 3.10.4
NetBSD 9.3: 3.9.13*
FreeBSD 12.4: 3.9.16
FreeBSD 13.1: 3.9.16
OpenBSD 7.2: 3.9.16
Note: Our VM tests install 3.9 explicitly for FreeBSD and 3.10 for
NetBSD; the default for "python" or "python3" in FreeBSD is
3.9.16. NetBSD does not appear to have a default meta-package, but
offers several options, the lowest of which is 3.7.15. "python39"
appears to be a pre-requisite to one of the other packages we request in
tests/vm/netbsd. pip, ensurepip and other Python essentials are
currently only available for Python 3.10 for NetBSD.
CentOS and OpenSUSE support parallel installation of multiple Python
interpreters, and binaries in /usr/bin will always use Python 3.6. However,
the newly introduced support for virtual environments ensures that all build
steps that execute QEMU Python code use a single interpreter.
Since it is safe to under our supported platform policy, bump our
minimum supported version of Python to 3.7.

configure: Add courtesy hint to Python version failure message
If we begin requiring Python 3.7+, a few platforms are going to need to
install an additional Python interpreter package.
As a courtesy to the user, suggest the optional package they might need
to install. This will hopefully minimize any downtime caused by the
change in Python dependency.

breaks on Python 3.8 with the following message:
AttributeError: 'FlakesChecker' object has no attribute 'CONSTANT'
Now that we do not support EOL'd Python versions anymore, we can
update to newer, fixed versions. It is a good time to do so, before
Python packages start dropping support for Python 3.7 as well!
The new mypy is also a bit smarter about which packages are actually
being used, so remove the now-unnecessary sections from setup.cfg.

build: move glib detection and workarounds to meson
QEMU adds the path to glib.h to all compilation commands. This is simpler
due to the pervasive use of static_library, and was grandfathered in from
the previous Make-based build system. Until Meson 0.63 the only way to
do this was to detect glib in configure and use add_project_arguments,
but now it is possible to use add_project_dependencies instead.
gmodule is detected in a separate variable, with export enabled for
modules and disabled for plugin.

meson: prepare move of QEMU_CFLAGS to meson
Clean up the handling of compiler flags in meson.build, splitting
the general flags that should be included in subprojects as well,
from warning flags that only apply to QEMU itself. The two were
mixed in both configure tests and meson tests.
This split makes it easier to move the compiler tests piecewise
from configure to Meson.
