Even though this has Rust disabled by default, I would still consider CI enablement to be a pre-requsite for merging even basic Rust support. > > MAINTAINERS | 21 + > configure | 170 +++++- >

I agree in general, but there's already a lot of work that can be parallelized and the idea of someone managing Rust-related patches out-of-tree was discarded. So this seemed to be the only way to proceed. Right now only Fedora 39 and 40 (with updates) are able to compile QEMU with Rust enabled. Full CI enablement requires further work to reduce the minimum supported version of the compiler, after which rustc can be added to the libvirt-ci inputs and to the Dockerfiles. Adding a CI job that uses nightly rust (via rustup) is high on my priority list, but first of all I wanted to integrate clippy (because the main point of having a job with nightly rust is to have a heads-up on future clippy warnings). That said, I'm also not sure how one would go adding rustup to a container generated by lcitool (for example should I add a new dockerfile that is _based_ on one that already exists? would that change when Rust/rustc is added to that dockerfile?). I think the best thing to do is to do a presentation to the whole community, maybe next week, explaining the state of the experiment and asking for help. Paolo

Full CI enablement isn't a requirement until we want to turn on Rust by default. It would be sufficient to have a single job in CI using Fedora 40 that passes '--enable-rust' to demonstrate that this at least working on one platform we expect. > Adding a CI job that uses nightly rust (via rustup) is high on my > priority list, but first of all I wanted to integrate clippy (because > the main point of having a job with nightly rust is to have a heads-up > on future clippy warnings).

Having layered dockerfiles is something we try to aviod these days, since each layer turns into another job dependancy in the CI pipeline, expanding the number of stages. If the job is merely to validate nightly clippy do we even need any of the rest of the QEMU build deps present ? Can we not just use a generic pre-existing Rust container and only run clippy in it. If we want to actually build with the cutting edge, then I'd say it is sufficient to have a container based on Fedora rawhide, since that gives a heads up on what's soon to be impacting the next stable distro release, upto 6 months ahead of time - we don't need to be watching& debugging stuff that hasn't even been released by Rust yet IMHO.

I forgot to say that QEMU's 'refresh' script can customize the dockerfiles from lcitool with an arbitrary amount of trailing text - see the 'debian12_extras' for example. > > If the job is merely to validate nightly clippy do we even need > any of the rest of the QEMU build deps present ?

I think it's a good idea to give ourselves early access to lints, given that clippy and rustc are evolving more rapidly than C compilers (which already bite us every now and then). It tells us whether we consider them over-the-top and disable them, or potential bugs/traps that we want to fix now. Paolo

So far I think the focus for Rust support has been on device models. But is there any interest in being able to write TCG plugins in Rust?

Just to expand a little. We do have: #define QEMU_PLUGIN_VERSION 4 and #define QEMU_PLUGIN_MIN_VERSION 2 which in theory should stop you getting mixed up trying to load older plugins when the APIs change. However we have only sporadically incremented the MIN_VERSION counter so you can still run into linking issues. Adding new APIs is fairly simple but we have also deprecated or changed the API signature for existing helpers. I think once that stabilises we'll be in a better position going forward. I'm certainly very interested in Rust as plugin implementation language. Although we limit their tentacles into QEMU itself they are still very performance sensitive and in C it's easy to take shortcuts that will blow up. However the current C interface makes heavy use of GLib types and that seems something that would be clumsy to pass across a Rust API. Would be implement Rust for plugins as a wrapper around the C API or implement a purer Rust API that dealt in idiomatic rust types? Would we even consider in the long run deprecating the C API in favour or rust? > > Paolo > > This project https://github.com/novafacing/qemu-rs seems to explore this > space - maybe it would be good to incorporate something like this inside > of QEMU? <snip> -- Alex Bennée Virtualisation Tech Lead @ Linaro

As you noticed, we are focused for now on making the API more complete and useful, before starting to think about extending languages available to write them. Rust will be on top of the list for sure! Regards, Pierrick
