By default, if Rust is passed `--target=foo` rather than a target.json file, it will infer a default sysroot if that component is installed. As the proposed aarch64 support [1] uses `aarch64-unknown-none` rather than a target.json file, this is needed [2] to prevent rustc from being confused between the custom kernel sysroot and the pre-installed one. [ Miguel: Applied Boqun's extra case (for `rusttest`) and reworded to add links to the arm64 patch series discussion. In addition, fixed the `rustdoc` target too (which requires a conditional since `cmd_rustdoc` is also used for host crates like `macros`). ] Signed-off-by: Matthew Maurer <mmaurer@google.com> Tested-by: Boqun Feng <boqun.feng@gmail.com> Reviewed-by: Alice Ryhl <aliceryhl@google.com> Link: https://lore.kernel.org/rust-for-linux/20231020155056.3495121-1-Jamie.Cunliffe@arm.com/ [1] Link: https://lore.kernel.org/rust-for-linux/CAGSQo01pOixiPXkW867h4vPUaAjtKtHGKhkV-rpifJvKxAf4Ww@mail.gmail.com/ [2] Link: https://lore.kernel.org/r/20231031201752.1189213-1-mmaurer@google.com Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
