In October 1, Rust for linux is under the linux-next, not stable
Thus this article would be out-of-date before Linux 6.1 stable comes.

Introduction #

Currently Apple Silicon mac series is only one ARM workstation that have powerful performance as normal desktop class workstation and can purchase anywhere. Of course if you have 32GB or bigger memory and least 8 big cores of apple silicon.

Btw, this article is in reference to .

VM hypervisor software selection. #

  • UTM : Free / OpenSource, QEMU based Sometimes tricky.
  • VM Fusion Tech Preview : Free for now / ClosedSource, Moderate
  • Parallels : Non-Free / ClosedSource, not my taste (sorry).

There’s some option working with Asahi Linux. But in this article is not consider native asahi linux environment.

In my case, I was chosen VM Fusion.

Virtual Machine Configuration #

Debian / Ubuntu Package Requirements #

# Install build-requirements for kernel compile with LLVM.
apt install clang git llvm-dev libclang-dev build-essential \
bc kmod cpio flex libncurses5-dev libelf-dev libssl-dev \
dwarves bison lld curl

Asahi Linux Package Requirements #

pacman -S base-devel cpio lld llvm llvm-libs bc libdwarf

Ready for rust #

Before build kernel, we need to install some packages.

curl --proto '=https' --tlsv1.2 -sSf | sh
rustup default 1.62
rustup component add rust-src
# rustfmt and clippy is need for later developing and debugging.
rustup component add rustfmt 
rustup component add clippy

Install rust with curl. You can select just default options. Also current rust for linux working with 1.62. Some native compile is working well with recent version (1.64 tested, but cross compile not working).

Clone linux from Rust-For-Linux #

Check working branch
State of current rust-for-linux, they are under 6.0 RC

# In my case use `Develop` as worksapce, you can replace this word. 
mkdir -p ~/Develop
cd ~/Develop
git clone -b rust

clone like this.

Necessary some rust scripts in Rust-For-Linux #

In cloned linux directory.

git clone --recurse-submodules \
        --branch $(scripts/ rustc) \ \
        $(rustc --print sysroot)/lib/rustlib/src/rust

This work clone rustlib repository in your rust toolchain directory.

cargo install --locked --version $(scripts/ bindgen) bindgen

This work need to bind existing c code to rust code. s


cd ~/Develop/linux
make LLVM=1 rustavailable
$ make LLVM=1 rustavailable
*** Rust compiler 'rustc' is too new. This may or may not work.
***   Your version:     1.64.0
***   Expected version: 1.62.0
Rust is available!

Than if you get result like this it’s good to go

Configure linux source code with menuconfig #

make ARCH=arm64 defconfig
make menuconfig

Disable GCC plugins #

Menuconfig Rust Support
General architecture-dependent options -> GCC plugins For now (6.1 rc*), GCC_PLUGINS config should be disabled for RUST_CONFIG config. Be sure disable it.

General setup -> Rust support #

Menuconfig Rust Support
In General setup -> Rust support , Enable this
If you don’t see the flag, double-check that the make LLVM=1 rustavailable process was successful.

For a detailed mailing thread on CONFIG_RUST see here. See details ⇀

Kernel hacking -> Sample kernel code #

For easy to develop rust kernel code we need some examples. You can get them with following menus.

Menuconfig Rust Sample1
Menuconfig Rust Sample2

In Kernel hacking -> Sample kernel code , enable it (not all of them..) when you interest. I don’t recommend you enable them when you write own driver. Because there’s some possibility make system slow or make unwanted log in dmesg.
In particular, the netflitter example outputs too many dmesg, so it is recommended that you disable it unless you are studying the netfilter example.

example too many dmesg log from netfilter example

Kernel hacking -> Rust hacking #

For debug rust kernel code or driver, need to enable some debug options.

Menuconfig Rust Debug

In Kernel hacking -> Rust hacking , enables it and inside menus.

Compile and install it in virtual machine. #

Build time

# -j4 for 4 core virtual machine, -j2 for 2 core, -j1 for single core.
make LLVM=1 -j4

Build with following command. You need to set number of job considering assigned number of cores for virtual machine. (-j#)

Also while you build it, it will ask some flag. I just select default in my case.

It takes lot of time (don’t worry much better than raspberry pi 4), 13~14 minuites takes in my environment (VM 4core, 8GB)

After than, install via following command

# should be under the root permision.
make modules_install
make install

make install rust-kernel

It’s done!.
Reboot program and then check the kernel working well.
