2023-09-25pc_piix: remove pc-i440fx-1.4 up to pc-i440fx-1.7Paolo Bonzini
These are the last users of the 128K SeaBIOS blob in the i440FX family. Removing them allows us to drop PCI support from the 128K blob, thus making it easier to update SeaBIOS to newer versions. Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-08-31accel: Remove HAX acceleratorPhilippe Mathieu-Daudé
HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark HAXM in QEMU as deprecated"), released in v8.0.0. Per the latest HAXM release (v7.8 [*]), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. It became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code.

In early 2021 (see commit 2ad784339e "docs: update README to use GitLab repo URLs") almost all of the code base was converted to point to GitLab instead of git.qemu.org.

2023-05-18Python: Drop support for Python 3.6Paolo Bonzini
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. Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Daniel P.

2023-05-02qmp: Deprecate 'singlestep' member of StatusInfoPeter Maydell
The 'singlestep' member of StatusInfo has never done what the QMP documentation claims it does. What it actually reports is whether TCG is working in "one guest instruction per translation block" mode. We no longer need this field for the HMP 'info status' command, as we've moved that information to 'info jit'. It seems unlikely that anybody is monitoring the state of this obscure TCG setting via QMP, especially since QMP provides no means for changing the setting. So simply deprecate the field, without providing any replacement. Until we do eventually delete the member, correct the misstatements in the QAPI documentation about it. If we do find that there are users for this, then the most likely way we would provide replacement access to the information would be to put the accelerator QOM object at a well-known path such as /machine/accel, which could then be used with the existing qom-set and qom-get commands.

The 'singlestep' HMP command is confusing, because it doesn't actually have anything to do with single-stepping the CPU. What it does do is force TCG emulation to put one guest instruction in each TB, which can be useful in some situations. Create a new HMP command 'one-insn-per-tb', so we can document that 'singlestep' is just a deprecated synonym for it, and eventually perhaps drop it.

2023-02-20docs: build-platforms: refine requirements on Python build dependenciesPaolo Bonzini
Historically, the critical dependency for both building and running QEMU has been the distro packages. Because QEMU is written in C and C's package management has been tied to distros (at least if you do not want to bundle libraries with the binary, otherwise I suppose you could use something like conda or wrapdb), C dependencies of QEMU would target the version that is shipped in relatively old but still commonly used distros. For non-C libraries, however, the situation is different, as these languages have their own package management tool (cpan, pip, gem, npm, and so on). For some of these languages, the amount of dependencies for even a simple program can easily balloon to the point that many distros have given up on packaging non-C code. For this reason, it has become increasingly normal for developers to download dependencies into a self-contained local environment, instead of relying on distro packages. Fortunately, this affects QEMU only at build time, as qemu.git does not package non-C artifacts such as the qemu.qmp package; but still, as we make more use of Python, we experience a clash between a support policy that is written for the C world, and dependencies (both direct and indirect) that increasingly do not care for the distro versions and are quick at moving past Python runtime versions that are declared end-of-life. For example, Python 3.6 has been EOL'd since December 2021 and Meson 0.62 (released the following March) already dropped support for it. Yet, Python 3.6 is the default version of the Python runtime for RHEL/CentOS 8 and SLE 15, respectively the penultimate and the most recent version of two distros that QEMU would like to support. (It is also the version used by Ubuntu 18.04, but QEMU stopped supporting it in April 2022). There are good reasons to move forward with the deprecation of Python 3.6 in QEMU as well: completing the configure->meson switch (which requires Meson 0.63), and making the QAPI generator fully typed (which requires newer versions of not just mypy but also Python, due to PEP563). Fortunately, these long-term support distros do include newer versions of the Python runtime. However, these more recent runtimes only come with a very small subset of the Python packages that the distro includes. Because most dependencies are optional tests (avocado, mypy, flake8) and Meson is bundled with QEMU, the most noticeably missing package is Sphinx (and the readthedocs theme). There are four possibilities: * we change the support policy and stop supporting CentOS 8 and SLE 15; not a good idea since CentOS 8 is not an unreasonable distro for us to want to continue to support * we keep supporting Python 3.6 until CentOS 8 and SLE 15 stop being supported. This is a possibility---but we may want to revise the support policy anyway because SLE 16 has not even been released, so this would mean delaying those desirable reasons for perhaps three years; * we support Python 3.6 just for building documentation, i.e. we are careful not to use Python 3.7+ features in our Sphinx extensions but are free to use them elsewhere. Besides being more complicated to understand for developers, this can be quite limiting; parts of the QAPI generator run at sphinx-build time, which would exclude one of the areas which would benefit from a newer version of the runtime; * we only support Python 3.7+, which means CentOS 8 CI and users have to either install Sphinx from pip or disable documentation. This proposed update to the support policy chooses the last of these possibilities. It does by modifying three aspects of the support policy: * it introduces different support periods for *native* vs. *non-native* dependencies. Non-native dependencies are currently Python ones only, and for simplicity the policy only mentions Python; however, the concept generalizes to other languages with a well-known upstream package manager, that users of older distributions can fetch dependencies from; * it opens up the possibility of taking non-native dependencies from their own package index instead of using the version in the distribution. The wording right now is specific to dependencies that are only required at build time. In the future we may have to refine it if, for example, parts of QEMU will be written in Rust; in that case, crates would be handled in a similar way to submodules and vendored in the release tarballs. * it mentions specifically that optional build dependencies are excluded from the platform policy. Tools such as mypy don't affect the ability to build QEMU and move fast enough that distros cannot standardize on a single version of them (for example RHEL9 does not package them at all, nor does it run them at rpmbuild time). In other cases, such as cross compilers, we have alternatives. Right now, non-native dependencies have to be download manually by running "pip" before "configure". In the future, it will be desirable for configure to set up a virtual environment and download them in the same way that it populates git submodules (but, in this case, without vendoring them in the release tarballs). Just like with submodules, this would make things easier for people that can afford accessing the network in their build environment; the option to populate the build environment manually would remain for people whose build machines lack network access. The change to the support policy neither requires nor forbids this future change. [Thanks to Daniel P.

Let's use a more appropriate wording for this command line and config file option. The old ones are still accepted for compatibility reasons, but marked as deprecated now so that it could be removed in a future version of QEMU. This change is based on earlier patches from Philippe Mathieu-Daudé, with the idea for the new option name suggested by BALATON Zoltan. And while we're at it, replace the "?" in the help text with "help" since that does not have the problem of conflicting with the wildcard character of the shells.
