How to make a kernel package for Raspberry Pi?

Reedych · 05-10-2017, 01:13 AM

I know about this helpful manual, but I don't understand what to do with compiled files. In x86 it's easy, but there are some kernel.img files. So I can't find any slackbuild to make a package. I know about source/ directory in the repo, but I think it's not for raspberry pi. Thanks!

Would you be able to rename the topic to include "Raspberry Pi" ? I was poised to write short treatise on how to build a Kernel using the build scripts in the ARM source tree, but as you noticed - it does not support the Raspberry Pi since it's not an officially supported device.
If someone were to search the forums for a similar question, it'd help to have a subject line more closely representing the question.

Thanks

Ok, thanks.

Can you explain what you are trying to achieve as an end result?

What version of Raspberry Pi are you building a kernel for?
Are you starting from scratch with building the kernel or do you have it already built and just want to make a package to install it?

When I needed to learn about Slackware packages I found Mozes' introduction to Slackware Packages (.PDF) a great resource. I pretty much picked up everything I needed to know from there, and Slack Docs was a great help too.

Raspberry Pi 3. I'm going to build the kernel and package it. I know how to use makepkg, but I don't understand the format of /boot.

In the /boot directory you need the Raspberry Pi firmware, including the /boot/overlays directory, and of course the kernel7.img

<edit> you could simply explode the sarpi3-boot-firmware-armv7-1_slackcurrent_fd0.txz package to view the contents and recreate it with your own kernel and latest firmware included.
