## How to update mbp-fedora-kernel



Starting from Fedora 37 `mbp-fedora` release - `mbp-fedora-kernel` should be automatically updated using builtin package manager - DNF, so simply run `dnf update --refresh`, and it should automatically fetch all required updates.



If the DNF fail, or you're updating your older `mbp-fedora`, you can still use previously used method with `update_kernel_mbp` described below.



```bash

### First run or if you want to update your copy of update_kernel_mbp script

sudo -i

curl -L https://raw.githubusercontent.com/mikeeq/mbp-fedora-kernel/v6.4-f38/update_kernel_mbp.sh -o /usr/bin/update_kernel_mbp

chmod +x /usr/bin/update_kernel_mbp

update_kernel_mbp



### Next runs

sudo -i

update_kernel_mbp



### Update to specific version of kernel

sudo -i

KERNEL_VERSION="6.4.16-f38" update_kernel_mbp



### Update to specific version of kernel using specific version of update script

#### Usually not needed, because scripts are shared between branches, but you can use it to update your update_kernel_mbp script

##### If the script fails, try to rerun it - it's due to self-upgrading feature of this script

sudo -i

KERNEL_VERSION="6.4.16-f38" UPDATE_SCRIPT_BRANCH="v6.4-f38" update_kernel_mbp



### If kernel update using dnf would file you can execute update_kernel_mbp script with `--github` argument, it will force it to use github to download kernel RPMs

sudo -i

update_kernel_mbp --github

```



## Known issues



- TouchID - (@MCMrARM is working on it - https://github.com/Dunedan/mbp-2016-linux/issues/71#issuecomment-528545490)

- Audio

  - Internal Microphone (it's recognized with new apple t2 sound driver, but there is a low mic volume amp)



### Partially working



- Suspend - really unstable, I recommend disabling it. If you would stuck in sleep mode, try to keep pressing power off button for a while to force poweroff and then turn on the Macbook.

- Touch Bar, if you encounter any issues, I recommend reboot to MacOS/Windows to initialize TouchBar and then back to Linux - it should fix the problem.



### Working with upstream stable kernel 6.0



- Display/Screen

- USB-C

- Battery/AC

- Ethernet/Video USB-C adapters

- Bluetooth

- NVMe

- Camera

- Thunderbolt



### Working with mbp-fedora-kernel



- with builtin BCE driver

  - Audio

  - Keyboard

  - Keyboard Backlight

  - Touchpad (scroll, right click)

- with builtin iBridge driver

  - MacBook Pro Touch Bar

    - If there's an issue with Touch Bar startup on Linux I recommend installing Win10 and boot it once a while to initialize Touch Bar using BootCamp driver, it seems to fix the issue

- WiFi

  - to make it working, you need to grab closed source Broadcom WiFi firmware from MacOS and put it under `/lib/firmware/brcm/` in Linux OS, see 



### Not tested



- eGPU



## How to build mbp-fedora-kernel



1. Make sure that Docker is installed and running correctly on your machine

2. Clone repo

3. Generate GPG key: `gpg --full-generate-key`, choose `RSA and RSA` and `Real name: mbp-fedora`

4. Change version in `build.sh`, 

5. Run `./build_in_docker.sh`
