ca5765c852 meson: qga: do not use deprecated meson.build_root()
The function will return the build root of the parent project if called from a
subproject; that is irrelevant for QEMU's usage but rarely desirable, and
therefore the function was deprecated and replaced by two functions
project_build_root() and global_build_root().  Replace it with the former.

Remove the sys.path hacking from device-crash-test, and add in a little

Modify the GitLab job recipes to create the tests/venv first, then run
device-crash-test from that venv.

f4c66f1705 tests: use tests/venv to run basevm.py-based scripts
This patch co-opts the virtual environment being used by avocado tests
to also run the basevm.py tests. This is being done in preparation for
for the qemu.qmp package being removed from qemu.git.

As part of the change, remove any sys.path() hacks and treat "qemu" as a
normal third-party import.

0e7647aa8a tests: install "qemu" namespace package into venv
This patch adds the "qemu" namespace package to the $build/tests/venv
directory. It does so in "editable" mode, which means that changes to
the source python directory will actively be reflected by the venv.

This patch also then removes any sys.path hacking from the avocado test
scripts directly. By doing this, the environment of where to find these
packages is managed entirely by the virtual environment and not by the
scripts themselves.

aa19dd33ce tests: use python3 as the python executable name
Use "python3" instead of "python" as per PEP0394:
https://peps.python.org/pep-0394/

This should always be defined (in a venv, at least!), matching the
preferred python shebang of "#!/usr/bin/env python3".

caa0f7cbaf tests: add "TESTS_PYTHON" variable to Makefile
This is a convenience feature: $(PYTHON) points to the Python executable
we were instructed to use by the configure script. We use that Python to
create a virtual environment with the "check-venv" target in
tests/Makefile.include.

$(TESTS_PYTHON) points to the Python executable belonging to the virtual
environment tied to the build. This Python executable is a symlink to
the binary used to create the venv, which will be the version provided
at configure time.

Using $(TESTS_PYTHON) therefore uses the $(PYTHON) executable, but with
paths modified to use packages installed to the venv.

e7874a50ff python: update for mypy 0.950
typeshed (included in mypy) recently updated to improve the typing for
WriteTransport objects. I was working around this, but now there's a
version where I shouldn't work around it.

Unfortunately this creates some minor ugliness if I want to support both
pre- and post-0.950 versions. For now, for my sanity, just disable the
unused-ignores warning.

d7caf13b5f x86: cpu: fixup number of addressable IDs for logical processors sharing cache
When QEMU is started with '-cpu host,host-cache-info=on', it will
passthrough host's number of logical processors sharing cache and
number of processor cores in the physical package. QEMU already
fixes up the later to correctly reflect number of configured cores
for VM, however number of logical processors sharing cache is still
comes from host CPU, which confuses guest started with:

       -machine q35,accel=kvm \
       -cpu host,host-cache-info=on,l3-cache=off \
       -smp 20,sockets=2,dies=1,cores=10,threads=1  \
       -numa node,nodeid=0,memdev=ram-node0 \
       -numa node,nodeid=1,memdev=ram-node1 \
       -numa cpu,socket-id=0,node-id=0 \
       -numa cpu,socket-id=1,node-id=1

on 2 socket Xeon 4210R host with 10 cores per socket
with CPUID[04H]:
      ...
        --- cache 3 ---
      cache type                           = unified cache (3)
      cache level                          = 0x3 (3)

      fully associative cache              = false
      maximum IDs for CPUs sharing cache   = 0x1f (31)
      maximum IDs for cores in pkg         = 0xf (15)
      ...
that doesn't match number of logical processors VM was
configured with and as result RHEL 9.0 guest complains:

   sched: CPU #10's llc-sibling CPU #0 is not on the same node! [node: 1 != 0]. Ignoring dependency.

Fix it by capping max number of logical processors to vcpus/socket
as it was configured, which fixes the issue.

Accourding Intel's CPUID[EAX=04H] resulting bits 31 - 26 in EAX
should be:
"
 **** The nearest power-of-2 integer that is not smaller than (1 + EAX[31:26]) is the number of unique
    Core_IDs reserved for addressing different processor cores in a physical package. Core ID is a subset of

24ce7aa77d modules: introduces module_kconfig directive
module_kconfig is a new directive that should be used with module_obj
whenever that module depends on the Kconfig to be enabled.

When the module is enabled in Kconfig we are sure that its dependencies
will be enabled as well, thus the module will be loaded without any
problem.

The correct way to use module_kconfig is by passing the Kconfig option
to module_kconfig (or the *config-devices.mak without CONFIG_).
