Arch Support¶

Currently, the Rust compiler (rustc) uses LLVM for code generation, which limits the supported architectures that can be targeted. In addition, support for building the kernel with LLVM/Clang varies (please see Building Linux with Clang/LLVM). This support is needed for bindgen which uses libclang.

Below is a general summary of architectures that currently work. Level of support corresponds to S values in the MAINTAINERS file.

Architecture	Level of support	Constraints
`arm64`	Maintained	Little Endian only.
`loongarch`	Maintained	-
`riscv`	Maintained	`riscv64` and LLVM/Clang only.
`um`	Maintained	-
`x86`	Maintained	`x86_64` only.
