Hey,
Maybe I am just missing something blatantly obvious here, but trying
to build rust support in -next fails for me. I am using ClangBuiltLinux
clang version 15.0.0 5b0788fef86ed7008a11f6ee19b9d86d42b6fcfa and LLD
15.0.0. Is it just expected that building -next with rust support is
not a good idea?
My defconfig is the default RISC-V one plus:
CONFIG_RUST=y
CONFIG_SAMPLES=y
CONFIG_SAMPLES_RUST=y
CONFIG_SAMPLE_RUST_MINIMAL=y
Thanks,
Conor.

Please see https://github.com/Rust-for-Linux/linux/issues/795 for details about the maple tree issue. I will update the `rust-next` branch next week with the new version of the patches; but if you are interested in developing, please use the development `rust` branch instead in GitHub for the moment. Cheers, Miguel

Ah right, sorry for the noise so.

Thanks Miguel, good to know! I'll just wait around for a new version. Just been trying to get my CI etc in order for when rust support lands, but it sounds like I should be okay as it's a known problem & not some only-broken-on-riscv thing. Thanks, Conor.

Yeah, it is a simple `bindgen` issue. Thanks a lot for making the effort to prepare your CI in advance! Cheers, Miguel
Rust support This is the patch series (v7) to add support for Rust as a second language to the Linux kernel. If you are interested in following this effort, please join us in the mailing list at: rust-for-linux@vger.kernel.org and take a look at the project itself at: https://github.com/Rust-for-Linux As usual, special thanks go to ISRG (Internet Security Research Group) and Google for their financial support on this endeavor. Cheers, Miguel -- # Rust support This cover letter explains the major changes and updates done since the previous ones. For those, please see: RFC: https://lore.kernel.org/lkml/20210414184604.23473-1-ojeda@kernel.org/ v1: https://lore.kernel.org/lkml/20210704202756.29107-1-ojeda@kernel.org/ v2: https://lore.kernel.org/lkml/20211206140313.5653-1-ojeda@kernel.org/ v3: https://lore.kernel.org/lkml/20220117053349.6804-1-ojeda@kernel.org/ v4: https://lore.kernel.org/lkml/20220212130410.6901-1-ojeda@kernel.org/ v5: https://lore.kernel.org/lkml/20220317181032.15436-1-ojeda@kernel.org/ v6: https://lore.kernel.org/lkml/20220507052451.12890-1-ojeda@kernel.org/ This is a small round to address the comments made in v6 plus a few related changes: - Added `%pA` to `Documentation/core-api/printk-formats.rst`. - Added `checkpatch.pl` patch to search for `%pA` in C code. - Added `checkpatch.pl` patch to enable language-independent checks. - Added UML (x86_64) support, for KUnit (thanks David Gow!). - Added inline licensing information ("Apache-2.0 OR MIT") in the commit message of the `alloc` patch, as well as in `rust/alloc/README.md` in the following patch. - Added SPDX license identifiers to `Documentation/rust/`. - Reformatted `Documentation/rust/arch-support.rst` list table into simple table. - Removed logo from documentation patch; used Linux GIF one for the Rust generated docs in its place (to be replaced with the SVG one once available). - Used `"GPL"` instead of `"GPL v2"` for the `license` field of the `module!` macro. - Moved `module_misc_device!` macro in `samples/rust/rust_random.rs` to the top of the file in `samples/rust/` for consistency. - Sorted `#include` lists in `rust/kernel/bindings_helper.h` and `rust/helpers.c`. - Fixed some English typos. - Made the patches more `checkpatch.pl`-clean overall. - Picked up Reviewed-by and Acked-by tags. ## Patch series status The Rust support is still to be considered experimental. However, support is good enough that kernel developers can start working on the Rust abstractions for subsystems and write drivers and other modules. The current series has just arrived in `linux-next`, as usual. Similarly, the preview docs for this series can be seen at: https://rust-for-linux.github.io/docs/kernel/ As usual, please see the following link for the live list of unstable Rust features we are using: https://github.com/Rust-for-Linux/linux/issues/2 ## Conferences, meetings and liaisons We would like to remind everyone about the Rust MC (microconference) of LPC 2022 (Linux Plumbers Conference): https://lpc.events/event/16/contributions/1159/ The Rust MC intends to cover talks and discussions on both Rust for Linux as well as other non-kernel Rust topics. The Call for Proposals is open! ## Acknowledgements The signatures in the main commits correspond to the people that wrote code that has ended up in them at the present time. For details on contributions to code and discussions, please see our repository: https://github.com/Rust-for-Linux/linux However, we would like to give credit to everyone that has contributed in one way or another to the Rust for Linux project. Since the previous cover letter: - Kees Cook for his reviews of some of the v6 patches. - David Gow and Brendan Higgins for their reviews of the KUnit prerequisite patch and their feedback. - Jonathan Corbet and Akira Yokosawa for their review of the documentation patch and feedback on documentation rules. - Gary Guo for working on improvements to the Rust compiler that could make our `static_assert!` macro applicable in more cases. - bjorn3 for working on making `rustc_parse_format` compile on a stable Rust compiler so that it may be used by lightweight formatting systems (for instance, by the kernel). - As usual, bjorn3 and Gary Guo for all the input on Rust compiler details, reviews and suggestions. - Esteban Blanc, Arthur Cohen and Martin Schmidt for rebasing their SPI abstraction work. - Maciej Falkowski for continuing his work on the Samsung Exynos TRNG driver and the required abstractions around it, such as adding `delay`, `ktime` and `iopoll` abstractions, new methods to `platform::Device` and run-time power management abstractions. - Yuheng Su for working on cleaning up the `Module::init` interface. - Peng Hao for working on wrapping `mm_struct`. - Sergio González Collado for continuing his work on the GitHub CI problem matchers. - Wei Liu for taking the time to answer questions from newcomers in Zulip. - Philip Li, Yujie Liu et al. for continuing their work on adding Rust support to the Intel 0DAY/LKP kernel test robot. - Philip Herron and Arthur Cohen (and his supporters Open Source Security and Embecosm) et al. for their ongoing work on GCC Rust. - Antoni Boucher (and his supporters) et al. for their ongoing work on `rustc_codegen_gcc`. - Mats Larsen, Marc Poulhiès et al. for their ongoing work on improving Rust support in Compiler Explorer. - Many folks that have reported issues, tested the project, helped spread the word, joined discussions and contributed in other ways!
