README
# 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).
```shell
$ 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=`.
To build verbosely, use `make V=1`.
Building on ARM64 macOS is supported with clang and LLVM; you need to use Homebrew to
install the required dependencies:
```shell
$ brew install llvm
```
After that, just type `make`.
### 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.
```shell
$ git clone --recursive https://github.com/AsahiLinux/m1n1.git
$ cd m1n1
$ podman-compose run m1n1 make
$ # or
$ docker-compose run m1n1 make
```
## Usage
Our [wiki](https://github.com/AsahiLinux/docs/wiki/m1n1%3AUser-Guide) has more information on how to
use m1n1.
To install on an OS container based on macOS <12.1, use `m1n1.macho`:
```shell
kmutil configure-boot -c m1n1.macho -v
```
To install on an OS container based on macOS >=12.1, use `m1n1.bin`:
```shell
kmutil configure-boot -c m1n1.bin --raw --entry-point 2048 --lowest-virtual-address 0 -v
```
## Payloads
m1n1 supports running payloads by simple concatenation:
```shell
$ cat build/m1n1.macho Image.gz build/dtb/apple-j274.dtb initramfs.cpio.gz > m1n1-payload.macho
$ cat build/m1n1.bin Image.gz build/dtb/apple-j274.dtb initramfs.cpio.gz > m1n1-payload.bin
```
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
