# PUI PUI Linux
This is the minimum linux for testing the apple virtualization framework (https://github.com/Code-Hex/vz). So I assumed to support architectures are only x86\_64 and aarch64 (arm64).
This vmlinux is actually very very small other than linux distributions.
Since file size is very small in totally, I can do testing on the any CI with download them.
## Kernel
What's supported:
- Internet
- VIRTIO (Virt device I/O)
- virtio blk device
- virtio console (via hvc drivers. e.g. `console=hvc0`)
- virtio filesystem (virtfs)
- af\_vsock
## Initramfs
Our initramfs has a very simple init system controlled by `fs/init` script on this repository root. this script will do:
- Mount any file systems (proc, sysfs and devfs).
- Setup console which is an user specified by a console kernel parameter.
- Find devices and add them to `/etc/inittab` and `/etc/securetty`.
You can use it with other linux distributions.
## Usage
### Build all
```
$ ./puipui-linux-tool
```
### Update Kernel config
```
$ ./puipui-linux-tool -u
```
## Hack
This tool is used musl cross compiler. On arm64 environment the tool will be downloaded those pre build toolchains from https://github.com/Code-Hex/musl-cross-make-arm64
