python: upgrade to Python3.12+

2026-09-02T19:02:58+00:00

With Python3.9 EOL and Python3.10 soon to be EOL (October 2026), and with ... no other supported build platform actually using Python 3.11, require the use of Python3.12 or later. Additionally, as part of this upgrade, remove the use of tomllib from mkvenv as it is now standard in the Python stdlib: leaving this transitional code in causes a regression with mypy which becomes confused about the overloaded use of 'tomllib'. Our current minimum requirements as determined by standard repository packages on supported distributions is as follows: distro EOS python3 pip setuptools sphinx wheel Reviewed-by: Daniel P.

python, meson: update meson required for Rust to 1.12.0

2026-08-20T07:06:43+00:00

Meson 1.11.0 brings support for parsing Cargo.toml inside QEMU's source tree, and Meson 1.12.0 brings support for cross-compilation of Cargo subprojects. Together, these two features allow QEMU to remove hundreds of lines of manual compilation scripts. Reviewed-by: Marc-André Lureau Signed-off-by: Paolo Bonzini

pythondeps: bump to meson 1.11.1

2026-04-30T13:50:18+00:00

Prior to 1.11.0, build with rust didn't use link_args. In QEMU case, it means that plugins could not work, since they rely on link_args to expose symbols from QEMU binary. https://mesonbuild.com/Release-notes-for-1-11-0.html#change-to-handling-of-linker-arguments-for-rust With this change, QEMU built with --enable-rust can pass all CI tests, including tests related to plugins.

python: add vendored qemu.qmp package

2026-02-24T18:11:11+00:00

In anticipation of deleting the python/qemu/qmp source from the tree, add a vendored version of the qemu.qmp package to ensure that "make check" can be run in isolated build environments, offline.

python/mkvenv: add mechanism to install local package(s)

2026-02-23T18:24:42+00:00

Currently, we "implicitly" install the local 'qemu' python package for 'make check-venv' with some logic inside tests/Makefile.include. I would like to make this installation explicit in pythondeps.toml instead. This patch adds a path constraint that can be used in lieu of version constraints to specify that a package should be installed from the source tree instead of from PyPI or vendored packages. This is done to allow us to install the python packages hosted inside of the tree while also processing dependencies; i.e. so that our "qemu" package can specify that it needs "qemu.qmp", which soon will not be included in qemu.git. This also has the benefit of being able to specify in a declarative configuration file that our pyvenv environment *will* have our local python packages installed and available without any PYTHONPATH hacks, which should simplify iotests, device-crash-test and functional tests without needing to manage local inclusion paths in environment variables. On the downsides, installing packages through mkvenv/ensuregroup means that there are extra steps we need to take in order to install a local package *offline*; namely we must disable build isolation (so we have access to setuptools) and we must also include python3-wheel in QEMU's build dependencies in order for "make check" to run successfully when in an offline, isolated environment. These extra dependencies are handled in a forthcoming commit; for now, nothing is utilizing this new pathway.

python/mkvenv: create timestamp file for each group "ensured"

2026-02-23T18:24:42+00:00

Each group ensured by the mkvenv script will create an empty timestamp file named {groupname}.group which can be used to conditionally trigger dependency installation from various scripts and build machinery.

python: fix msys64 wheel directory specification

2026-02-02T06:46:40+00:00

In python3.14, fixes were made to the file URI parsing [1] such that file URIs that used to work but were technically out of spec are now broken. As a result, our msys2 GitLab CI tests began failing. Stop using "file://" URI links in favor of simple paths (Thanks pbo) to fix parsing errors under Python 3.14 and fix the msys2 GitLab CI tests.
