I'm getting garbage from the low-power audio input (lpai) mic which exists solely for voicetrigger. The garbage specifically is `61 7b` repeated. Obviously no voicetrigger report because there's nothing useful in lpai output. I'm suspecting its an mca/clock issue (maybe even SEP/permissions) because there's nothing suspicious from the aop RX/TX IPC side. ``` [audio.audio] Report REPORT/0xee #0 [audio.audio] unknown report: 0xee 00000000 c5 96 20 01 00 00 00 00 9c f5 10 00 00 00 00 00 |.. .............| 00000010 b8 07 00 00 20 30 6e 69 01 00 00 00 43 02 00 00 |.... 0ni....C...| 00000020 00 00 00 00 c5 96 20 01 00 00 00 00 00 00 00 00 |...... .........| 00000030 a4 07 00 00 9a 07 00 00 61 7b 61 7b 61 7b 61 7b |........a{a{a{a{| 00000040 61 7b 61 7b 61 7b 61 7b 61 7b 61 7b 61 7b 61 7b |a{a{a{a{a{a{a{a{| 00000050 * 000007b0 61 7b 61 7b 61 7b 61 7b |a{a{a{a{ | ``` Signed-off-by: Eileen Yoon <eyn@gmx.com> |

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).
$ 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:
$ 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.
$ 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 has more information on how to use m1n1.
To install on an OS container based on macOS <12.1, use m1n1.macho:
kmutil configure-boot -c m1n1.macho -v <path to your OS volume>
To install on an OS container based on macOS >=12.1, use m1n1.bin:
kmutil configure-boot -c m1n1.bin --raw --entry-point 2048 --lowest-virtual-address 0 -v <path to your OS volume>
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
$ 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
