GenPi Image on a Raspberry Pi 5

[AvroRJX]

Describe the bug
Below is an outline of the steps required to enable the GenPi64 image to boot on a Raspberry Pi 5.

To Reproduce
Steps to reproduce the behavior:
Mount a current GenPi64 image as chroot, also mount the /boot partition. Enter the chroot.

• edit /etc/portage/repos.conf/genpi64.conf and change the line:

sync-git-clone-extra-opts = -single-branch branch master 

to read:

sync-git-clone-extra-opts = -single-branch -branch rpi5-kernel

• If you are starting with a fresh image the repositories are empty to save space. So sync the genpi64 repository with the command:
  emaint -r genpi64 sync

after making the edit above.

If you have already synced the repositories I think it is necessary to delete everything under /var/db/repos/genpi64 and use the command above to resync the repository based on the rpi5-kernel branch.

• create dist-kernel-6.1.63.ebuild by copying and renaming the latest version
• Create the manifest for the 6.1.63 kernel:
  ebuild raspberrypi-kernel-6.1.63.ebuild manifest
• Create /etc/portage/package.unmask directory
• Create a file in the above directory containing the line below to unmask the virtual file
  =virtual/dist-kernel-6.1.63
• Create a file in /etc/portage/package.keywords containing the lines below to unmask the updated kernel
  sys-kernel/raspberrypi-kernel ~arm64
  virtual/dist-kernel-6.1.63 ~arm64
• These steps should now allow you to emerge the 6.1.63 kernel
  emerge -avu —-ignore-default-opts sys-kernel/raspberrypi-kernel
  A few hours later you should have the 6.1.63 kernel installed
• The edit the /boot/config.txt file and add the following lines
  [pi5]
  kernel=kernel8-p4.img
  dtoverlay=vc4-kms-v3d-pi5
  max_framebuffers=2

Expected behavior
Updated image should boot on a RPi 5

create dist-kernel-6.1.63.ebuild by copying and renaming the latest version
Create the manifest for the 6.1.63 kernel: ebuild raspberrypi-kernel-6.1.63.ebuild manifest

In this first line is dist-kernel-6.1.63 supposed to be raspberrypi-kernel-6.1.63 ?

[AvroRJX]

That line is correct but I missed out an important prior step which is to enable the rpi5-branch of the genpi64 overlay in order to make the raspberrypi-kernel-6.1.63 ebuild available. I’ve updated the instructions about to add the necessary steps.
