docs: rust: quick-start: remove GDB/Binutils mention

2026-04-07T08:00:25+00:00

The versions provided nowadays by even a distribution like Debian Stable (and Debian Old Stable) are newer than those mentioned [1]. Thus remove the workaround. Note that the minimum binutils version in the kernel is still 2.30, so one could argue part of the note is still relevant, but it is unlikely a kernel developer using such an old binutils is enabling Rust on a modern kernel, especially when using distribution toolchains, e.g. the Rust minimum version is not satisfied by Debian Old Stable. So we are at the point where keeping the docs short and relevant for essentially everyone is probably the better trade-off.

docs: rust: quick-start: remove Nix "unstable channel" note

2026-04-07T08:00:25+00:00

Nix does not need the "unstable channel" note, since its packages are recent enough even in the stable channel [1][2]. Thus remove it to simplify the documentation.

docs: rust: quick-start: add Ubuntu 26.04 LTS and remove subsection title

2026-04-07T08:00:25+00:00

Ubuntu 26.04 LTS (Resolute Raccoon) is scheduled to be released in a few weeks [1], and it has a recent enough Rust toolchain, just like Ubuntu 25.10 has [2][3]. We could update the title and the paragraph, but to simplify and to make it more consistent with the other distributions' sections, let's instead just remove that title. It will also reduce the differences later on to keep it updated. Eventually, when we remove the remaining subsection for older LTSs, Ubuntu should be a small section like the other distributions. Thus remove the title and add the mention of Ubuntu 26.04 LTS.

docs: rust: quick-start: update minimum Ubuntu version

2026-04-07T08:00:25+00:00

Ubuntu 25.04 is out of support [1], and Ubuntu 25.10 is the latest supported one. Moreover, Ubuntu 25.10 is the first that provides a recent enough Rust given the minimum bump -- they provide 1.85.1 [2]. Thus update it.

docs: rust: quick-start: update Ubuntu versioned packages

2026-04-07T08:00:25+00:00

Now that the minimum supported Rust version is bumped, bump the versioned Rust packages [1][2][3][4] to that version for Ubuntu in the Quick Start guide. In addition, add "may" to the `RUST_LIB_SRC` line since it does not look like it is needed from a quick test in a Ubuntu 24.04 LTS container.

docs: rust: quick-start: openSUSE provides `rust-src` package nowadays

docs: rust: quick-start: add Debian 13 (Trixie)

2025-11-04T19:21:15+00:00

Debian 13 (released 2025-08-09) packages Rust 1.85.0 [1], which is recent enough to build Linux. Thus document it. In fact, we are planning to propose that the minimum supported Rust version in Linux follows Debian Stable releases, with Debian 13 being the first one we upgrade to, i.e. Rust 1.85.

docs: rust: quick-start: update Ubuntu instructions

2025-05-22T22:12:14+00:00

Split installation instructions for Ubuntu into 2 different sections: - For Ubuntu 25.04: this release provides easy-to-install Rust packages. - For Ubuntu 24.10 and below: these releases provide rust-1.80 and bindgen-0.65, which do not set their tools as defaults. The instructions for these versions have been updated to configure Rust tools properly.

rust: remove leftover mentions of the `alloc` crate

In commit 392e34b6bc22 ("kbuild: rust: remove the `alloc` crate and `GlobalAlloc`") we stopped using the upstream `alloc` crate. Thus remove a few leftover mentions treewide.
