2023-03-24Revert "docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation"Thomas Huth1-9/+0
This reverts commit 1d0a8eba38cdddd028ea02c6e0b68f0a4c9a3cbf. The commit made the wrong assumption that 64-bit distros are most common these days on arm devices, but as Liviu Ionescu pointed out, the recommended OS for the very popular Raspberry Pi boards is still the 32-bit variant, and thus likely still used by a lot of people: https://www.raspberrypi.com/software/operating-systems/ Thus it's likely still a little bit too early to put this host environment on the deprecation list and we should wait a little bit longer 'til 64-bit distros are the predominant ones.

2023-03-21docs/system/arm/cpu-features.rst: Fix formattingPeter Maydell1-42/+34
The markup for the Arm CPU feature documentation is incorrect, and results in the HTML not rendering correctly -- the first line of each description is rendered in boldface as if it were part of the option name. Reformat to match the styling used in cpu-models-x86.rst.inc.

2023-03-16docs/sphinx/kerneldoc.py: Honour --enable-werrorPeter Maydell2-1/+6
Currently, the kerneldoc Sphinx plugin doesn't honour the --enable-werror configure option, so its warnings are never fatal. This is because although we do pass sphinx-build the -W switch, the warnings from kerneldoc are produced by the scripts/kernel-doc script directly and don't go through Sphinx's "emit a warning" function. When --enable-werror is in effect, pass sphinx-build an extra argument -Dkerneldoc_werror=1. The kerneldoc plugin can then use this to determine whether it should be passing the kernel-doc script -Werror. We do this because there is no documented mechanism for a Sphinx plugin to determine whether sphinx-build was passed -W or not; if one is provided then we can switch to that at a later date: https://github.com/sphinx-doc/sphinx/issues/11239 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Thomas Huth <thuth@redhat.com> Message-Id: <20230314114431.1096972-1-peter.maydell@linaro.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu>

Configuring the accelerator should nowadays be done via the "-accel" command line parameter, and thus via the "[accel]" section in config files. We also need this change for the upcoming qtests that will use these config files, since the qtests are already using "-accel" for setting the "qtest" accelerator and QEMU does not like mixing "-accel ..." and "-machine accel=...".

2023-03-08docs/about/deprecated: Deprecate 32-bit arm hosts for system emulationThomas Huth1-0/+9
For running QEMU in system emulation mode, the user needs a rather strong host system, i.e. not only an embedded low-frequency controller. All recent beefy arm host machines should support 64-bit now, it's unlikely that anybody is still seriously using QEMU on a 32-bit arm CPU, so we deprecate the 32-bit arm hosts here to finally save use some time and precious CI minutes.

2023-03-07docs/about/build-platforms: Refine the distro support policyThomas Huth1-1/+2
For long-term distributions that release a new version only very seldom, we limit the support to five years after the initial release. Otherwise, we might need to support distros like openSUSE 15 for up to 7 or even more years in total due to our "two more years after the next major release" rule, which is just way too much to handle in a project like QEMU that only has limited human resources.

2023-03-07qatomic: add smp_mb__before/after_rmw()Paolo Bonzini1-5/+21
On ARM, seqcst loads and stores (which QEMU does not use) are compiled respectively as LDAR and STLR instructions. Even though LDAR is also used for load-acquire operations, it also waits for all STLRs to leave the store buffer. Thus, LDAR and STLR alone are load-acquire and store-release operations, but LDAR also provides store-against-load ordering as long as the previous store is a STLR. Compare this to ARMv7, where store-release is DMB+STR and load-acquire is LDR+DMB, but an additional DMB is needed between store-seqcst and load-seqcst (e.g. DMB+STR+DMB+LDR+DMB); or with x86, where MOV provides load-acquire and store-release semantics and the two can be reordered. Likewise, on ARM sequentially consistent read-modify-write operations only need to use LDAXR and STLXR respectively for the load and the store, while on x86 they need to use the stronger LOCK prefix. In a strange twist of events, however, the _stronger_ semantics of the ARM instructions can end up causing bugs on ARM, not on x86. The problems occur when seqcst atomics are mixed with relaxed atomics. QEMU's atomics try to bridge the Linux API (that most of the developers are familiar with) and the C11 API, and the two have a substantial difference: - in Linux, strongly-ordered atomics such as atomic_add_return() affect the global ordering of _all_ memory operations, including for example READ_ONCE()/WRITE_ONCE() - in C11, sequentially consistent atomics (except for seq-cst fences) only affect the ordering of sequentially consistent operations. In particular, since relaxed loads are done with LDR on ARM, they are not ordered against seqcst stores (which are done with STLR). QEMU implements high-level synchronization primitives with the idea that the primitives contain the necessary memory barriers, and the callers can use relaxed atomics (qatomic_read/qatomic_set) or even regular accesses. This is very much incompatible with the C11 view that seqcst accesses are only ordered against other seqcst accesses, and requires using seqcst fences as in the following example: qatomic_set(&y, 1); qatomic_set(&x, 1); smp_mb(); smp_mb(); ... qatomic_read(&x) ... ... qatomic_read(&y) ... When a qatomic_*() read-modify write operation is used instead of one or both stores, developers that are more familiar with the Linux API may be tempted to omit the smp_mb(), which will work on x86 but not on ARM. This nasty difference between Linux and C11 read-modify-write operations has already caused issues in util/async.c and more are being found. Provide something similar to Linux smp_mb__before/after_atomic(); this has the double function of documenting clearly why there is a memory barrier, and avoiding a double barrier on x86 and s390x systems. The new macro can already be put to use in qatomic_mb_set().

2023-02-27meson: stop looking for 'sphinx-build-3'John Snow1-7/+2
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.

The code always runs find_program, rather than waiting to build qemu-keymap, because it looks for CONFIG_XKBCOMMON in config_host rather than config_host_data. Making serially succeeds, by soft linking files from pc-bios/keymaps, but that is not the desired result for enable-xkbcommon.

2023-02-20docs: build-platforms: refine requirements on Python build dependenciesPaolo Bonzini1-0/+32
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.
