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
