== About this Howto ==
This documentation is about using Raspberry Pi Foundation [[https://github.com/raspberrypi/linux|downstream kernel]] and components from Fedora userspace.
The Workstation flavor is recommended for the Raspberry Pi 4 B/400 with >=4GB RAM platform. The Server flavor is usable on starting from Raspberry Pi 3 B/B+.

== Kickstart files ==
Kickstart files are located at [[https://pagure.io/fork/dwrobel/fedora-kickstarts||fedora-kickstarts]] repository and are based on the original
Fedora 41 files with the following modifications:
 || component         || Repositories                                                                                                                                   || comment ||

 || pykickstart       || [[https://github.com/pykickstart/pykickstart/pull/275|PR]]   / [[https://copr.fedorainfracloud.org/coprs/dwrobel/pykickstart/|copr]]           || Adds --priority=<priority> ||
 || livecd-tools      || [[https://github.com/livecd-tools/livecd-tools/pull/134|PR]] / [[https://copr.fedorainfracloud.org/coprs/dwrobel/livecd-tools/|copr]]          || Adds support for repository 'priority' configuration ||

The modifications in livecd-tools and pykickstart allows to generate image with selected downstream kernel (despite it has lower version) over the upstream one. On a system, all aforementioned repositories are installed with '''priority=50''' option to instruct 'dnf' to choose packages from this repository, rather then Fedora default.

== Pre-built images (f41) ==
The location of pre-generated images for Fedora 41 can be found below:
|| Flavor      || aarch64                                                                      ||

|| Workstation || [[https://ufile.io/dffuf1vo|image]] / [[https://ufile.io/ub1cilsg|checksum]] ||

== Pre-built images (f40) ==
The location of pre-generated images for Fedora 40 can be found below:
|| Flavor      || aarch64                                                                      ||

== Updating Raspberry Pi 4 bootloader EEPROM ==

Follow the gist available at: [[https://gist.github.com/dwrobel/266ad5d4e59b05ea26d8bb6725118578|https://gist.github.com/dwrobel/266ad5d4e59b05ea26d8bb6725118578]].

== Raspberry Pi 5 ==

Despite that Rasberry Pi 5 is not supported, images for F41 are [[https://discussion.fedoraproject.org/t/dwrobel-kernel-rpi/17877/25|reported to work]] with the following content appended to the '''/boot/config.txt''' file:
{{{
[pi5]
# Automatically load overlays for detected cameras
camera_auto_detect=1

# Automatically load overlays for detected DSI displays
display_auto_detect=1

# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d

# Allows the default turbo-mode clock to be increased from 1.5GHz to 1.8GHz
# Based on https://www.raspberrypi.com/documentation/computers/config_txt.html#arm_boost-raspberry-pi-4-only
arm_boost=1

disable_overscan=1
}}}
Note: Basically it is the '''[pi4]''' section duplicated as '''[pi5]'''.

== Configurations ==
=== Booting from external USB drive ===
Write the image to the external drive, then mount the filesystem and change '''root=/dev/mmcblk0p2''' to '''root=/dev/sda2''' in the '''/boot/efi/cmdline.txt'''.

Note: On the Raspberry Pi 4, you may need to adjust [[https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#BOOT_ORDER|BOOT_ORDER=]] parameter in order be able to boot from the external drive.

=== Resizing filesystem ===
After booting the system, please consider to resize the filesystem.
The following example assumes system booted from internal SD card.
{{{
sudo growpart -u on /dev/mmcblk0 2
sudo btrfs filesystem resize max /
}}}

== Bug Report ==
 * Downstream bugs on the kernel can be reported to https://github.com/raspberrypi/linux/
