m1n1: an experimentation playground for Apple Silicon

(And to some extent a Linux bootloader)

Building

You need an aarch64-linux-gnu-gcc cross-compiler toolchain (or a native one, if running on ARM64). You also need dtc (the devicetree compiler) and convert (from ImageMagick) for the boot logos.

$ git clone --recursive https://github.com/AsahiLinux/m1n1.git
$ cd m1n1
$ make

The output will be in build/m1n1.macho.

To build on a native arm64 machine, use make ARCH=.

Building using the container setup

If you have a container runtime installed, like Podman or Docker, you can make use of the compose setup, which contains all build dependencies.

$ git clone --recursive https://github.com/AsahiLinux/m1n1.git
$ cd m1n1
$ podman-compose run m1n1 make
$ # or
$ docker-compose run m1n1 make

Usage

Our developer quickstart guide has more information on how to use m1n1.

Payloads

m1n1 supports running payloads by simple concatenation:

$ cat build/m1n1.macho Image.gz build/dtb/apple-j274.dtb initramfs.cpio.gz > m1n1-payload.macho

Supported payload file formats:

  • Kernel images (or compatible). Must be compressed or last payload.
  • Devicetree blobs (FDT). May be uncompressed or compressed.
  • Initramfs cpio images. Must be compressed.

Supported compression formats:

  • gzip
  • xz
