2025-07-15vfio/migration: Max in-flight VFIO device state buffers size limitMaciej S. Szmigiero1-0/+13
Allow capping the maximum total size of in-flight VFIO device state buffers queued at the destination, otherwise a malicious QEMU source could theoretically cause the target QEMU to allocate unlimited amounts of memory for buffers-in-flight. Since this is not expected to be a realistic threat in most of VFIO live migration use cases and the right value depends on the particular setup disable this limit by default by setting it to UINT64_MAX.

This form is used to annotate a return type without an accompanying description, for when there is no "Returns:" information in the source doc, but we have a return type we want to generate a cross-reference to. The syntax is: :return-nodesc: TypeName It's primarily necessary because Sphinx always expects both a type and a description for the prior form and will format it accordingly. To have a reasonable rendering when the body is missing, we need to use a different info field list entirely.

2025-07-11migration: Rename save_live_complete_precopy_thread to ↵Juraj Marcin1-2/+2
save_complete_precopy_thread Recent patch [1] renames the save_live_complete_precopy handler to save_complete, as the machine is not live in most cases when this handler is executed. The same is true also for save_live_complete_precopy_thread, therefore this patch removes the "live" keyword from the handler itself and related types to keep the naming unified. In contrast to save_complete, this handler is only executed at the end of precopy, therefore the "precopy" keyword is retained.

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.

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...

2025-06-03rust: 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>

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.

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.

2025-05-06docs: Don't define duplicate label in qemu-block-drivers.rst.incPeter Maydell1-1/+1
Sphinx requires that labels within documents are unique across the whole manual. This is because the "create a hyperlink" directive specifies only the name of the label, not a filename+label. Some Sphinx versions will warn about duplicate labels, but even if there is no warning there is still an ambiguity and no guarantee that the hyperlink will be created to the right target. For QEMU this is awkward, because we have various .rst.inc fragments which we include into multiple .rst files. If you define a label in the .rst.inc file then it will be a duplicate label. We have mostly worked around this by not putting labels into those .rst.inc files, or by adding "insert a label" functionality into the hxtool extension (see commit 1eeb432a953b0 "doc/sphinx/hxtool.py: add optional label argument to SRST directive"). Unfortunately in commit 7f6314427e78 ("docs/devel: add a codebase section") we accidentally added a duplicate label, because not all Sphinx versions warn about the mistake. In this case the link was only from the developer docs codebase summary, so as the simplest fix for the stable branch, we drop the link entirely.

2025-05-02rust/hpet: Support migrationZhao Liu1-2/+1
Based on commit 1433e38cc8 ("hpet: do not overwrite properties on post_load"), add the basic migration support to Rust HPET. The current migration implementation introduces multiple unsafe callbacks. Before the vmstate builder, one possible cleanup approach is to wrap callbacks in the vmstate binding using a method similar to the vmstate_exist_fn macro. However, this approach would also create a lot of repetitive code (since vmstate has so many callbacks: pre_load, post_load, pre_save, post_save, needed and dev_unplug_pending). Although it would be cleaner, it would somewhat deviate from the path of the vmstate builder. Therefore, firstly focus on completing the functionality of HPET, and those current unsafe callbacks can at least clearly indicate the needed functionality of vmstate. The next step is to consider refactoring vmstate to move towards the vmstate builder direction. Additionally, update rust.rst about Rust HPET can support migration.
