5 dayshw/arm/highbank: Mark the "highbank" and the "midway" machine as deprecatedThomas Huth1-0/+7
We don't have any automatic regression tests for these machines and when asking the usual suspects on the mailing list we came to the conclusion that nobody tests these machines manually, too, so it seems like this is currently just completely unused code. Mark them as depre- cated to see whether anybody still speaks up during the deprecation period, otherwise we can likely remove these two machines in a couple of releases.

2025-06-24docs: define policy forbidding use of AI code generatorsDaniel P. Berrangé1-1/+54
There has been an explosion of interest in so called AI code generators. Thus far though, this is has not been matched by a broadly accepted legal interpretation of the licensing implications for code generator outputs. While the vendors may claim there is no problem and a free choice of license is possible, they have an inherent conflict of interest in promoting this interpretation. More broadly there is, as yet, no broad consensus on the licensing implications of code generators trained on inputs under a wide variety of licenses The DCO requires contributors to assert they have the right to contribute under the designated project license. Given the lack of consensus on the licensing of AI code generator output, it is not considered credible to assert compliance with the DCO clause (b) or (c) where a patch includes such generated code. This patch thus defines a policy that the QEMU project will currently not accept contributions where use of AI code generators is either known, or suspected. These are early days of AI-assisted software development. The legal questions will be resolved eventually. The tools will mature, and we can expect some to become safely usable in free software projects. The policy we set now must be for today, and be open to revision. It's best to start strict and safe, then relax. Meanwhile requests for exceptions can also be considered on a case by case basis. Signed-off-by: Daniel P.

2025-06-24docs: define policy limiting the inclusion of generated filesDaniel P. Berrangé1-0/+55
Files contributed to QEMU are generally expected to be provided in the preferred format for manipulation. IOW, we generally don't expect to have generated / compiled code included in the tree, rather, we expect to run the code generator / compiler as part of the build process. There are some obvious exceptions to this seen in our existing tree, the biggest one being the inclusion of many binary firmware ROMs. A more niche example is the inclusion of a generated eBPF program. Or the CI dockerfiles which are mostly auto-generated. In these cases, however, the preferred format source code is still required to be included, alongside the generated output. Tools which perform user defined algorithmic transformations on code are not considered to be "code generators". ie, we permit use of coccinelle, spell checkers, and sed/awk/etc to manipulate code. Such use of automated manipulation should still be declared in the commit message. One off generators which create a boilerplate file which the author then fills in, are acceptable if their output has clear copyright and license status. This could be where a contributor writes a throwaway python script to automate creation of some mundane piece of code for example. Signed-off-by: Daniel P.

Currently we have a short paragraph saying that patches must include a Signed-off-by line, and merely link to the kernel documentation. The linked kernel docs have a lot of content beyond the part about sign-off an thus are misleading/distracting to QEMU contributors. This introduces a dedicated 'code-provenance' page in QEMU talking about why we require sign-off, explaining the other tags we commonly use, and what to do in some edge cases.

A log_mask_ln!() macro is provided which expects similar arguments as the C version. However, the formatting works as one would expect from Rust. To maximize code reuse the macro is just a thin wrapper around qemu_log(). Also, just the bare minimum of logging masks is provided which should suffice for the current use case of Rust in QEMU.

2025-06-05rust: qemu-api: add bindings to ErrorPaolo Bonzini1-0/+5
Provide an implementation of std::error::Error that bridges the Rust anyhow::Error and std::panic::Location types with QEMU's Error*. It also has several utility methods, analogous to error_propagate(), that convert a Result into a return value + Error** pair. One important difference is that these propagation methods *panic* if *errp is NULL, unlike error_propagate() which eats subsequent errors[1]. The reason for this is that in C you have an error_set*() call at the site where the error is created, and calls to error_propagate() are relatively rare. In Rust instead, even though these functions do "propagate" a qemu_api::Error into a C Error**, there is no error_setg() anywhere that could check for non-NULL errp and call abort(). error_propagate()'s behavior of ignoring subsequent errors is generally considered weird, and there would be a bigger risk of triggering it from Rust code. [1] This is actually a violation of the preconditions of error_propagate(), so it should not happen. But you never know...

2025-06-05docs/qapidoc: linting fixesJohn Snow2-13/+17
This restores the linting baseline in qapidoc. The order of some imports change slightly here due to configuring isort a little better: previously, isort was having difficulty understanding that "compat" and "qapidoc_legacy" were local modules because docs/sphinx "isn't a python package". Configuring this manually, isort chooses a different import ordering, which _is_ intentional here. Also: extra ignores are added for pylint. The most recent versions of pylint don't require these ignores, but the oldest versions we support do, so in the extra ignores go.

2025-06-03rust: use native Meson support for clippy and rustdocPaolo Bonzini1-3/+7
Meson has support for invoking clippy and rustdoc on all crates (1.7.0 for clippy, 1.8.0 for rustdoc). Use it instead of the homegrown version; this requires disabling the multiple_crate_versions lint (the only one that was enabled from the "cargo" group)---which was not particularly useful anyway because all dependencies are converted by hand into Meson subprojects. rustfmt is still not supported.

2025-06-03rust: add qemu-api doctests to "meson test"Paolo Bonzini1-0/+2
Doctests are weird. They are essentially integration tests, but they're "ran" by executing rustdoc --test, which takes a compiler-ish command line. This is supported by Meson 1.8.0. Because they run the linker and need all the .o files, run them in the build jobs rather than the test jobs. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

libqemuutil is not meant be linked as a whole; if modules are enabled, doing so results in undefined symbols (corresponding to QMP commands) in rust/qemu-api/rust-qemu-api-integration. Support for "objects" in Rust executables is available in Meson 1.8.0; use it to switching to the same dependencies that C targets use: link_with for libqemuutil, and objects for everything else.

2025-05-12rust: pl011: Really use RX FIFO depthPaolo Bonzini1-1/+1
While we model a 16-elements RX FIFO since the PL011 model was introduced in commit cdbdb648b7c ("ARM Versatile Platform Baseboard emulation"), we only read 1 char at a time! Have can_receive() return how many elements are available, and use that in receive(). This is the Rust version of commit 3e0f118f825 ("hw/char/pl011: Really use RX FIFO depth"); but it also adds back a comment that is present in commit f576e0733cc ("hw/char/pl011: Add support for loopback") and absent in the Rust code.
