# t2linux-fedora-kernel

This is a patched kernel for Fedora on T2 macs. A `dnf` repo is avaliable by installing the `t2linux-repo` package from the latest [release](https://github.com/t2linux/fedora-kernel/releases/latest).

The internal ssd, camera, mic, and the keyboard/trackpad work out of the box. WiFi and Bluetooth work with some extra steps. Read [this](https://wiki.t2linux.org/state/) for information about the latest hardware support.

This kernel is usually at the same version as the stable Fedora kernel. It is currently built for Fedora 38.

## Instalation

Download the live ISO from [here](https://github.com/t2linux/fedora-iso). Follow the [installation guide](https://wiki.t2linux.org/distributions/fedora/installation/).

## WiFi/Bluetooth

Follow the [firmware guide](https://wiki.t2linux.org/guides/wifi/). When you get to the [On Linux](https://wiki.t2linux.org/guides/wifi-bluetooth/#on-linux) section, you can just run `firmware.sh`.

## Troubleshooting

- Problem: The touchbar is not working and is blank  
   Solution: Reboot into MacOS Recovery by holding `command`+`r` while booting up, then reboot into Fedora again.

- Problem: Suspend is not working  
   Solution: Put this in `/usr/lib/systemd/system-sleep/rmmod_wifi.sh`:
  ```bash
  #!/usr/bin/env bash
  if [ "${1}" = "pre" ]; then
          modprobe -r brcmfmac_wcc
          modprobe -r brcmfmac
  elif [ "${1}" = "post" ]; then
          modprobe brcmfmac
  fi
  ```

## Building from source

Clone this repo locally:

```bash
git clone --depth 1 https://github.com/t2linux/fedora-kernel
cd t2linux-fedora-kernel
```

Then run the build container, which has dependencies already installed. The packages will be in the `_output` directory:

```bash
podman run -it -v "$PWD":/repo ghcr.io/t2linux/fedora-dev:latest /repo/build-packages.sh
```
