Directions to rebuild kernel and/or add kernel modules? #43

Closed dazKind closed 4 years ago

dazKind commented 4 years ago

I wanna run a couple of bpi m2+ zeros with docker inside an ad-hoc wifi mesh.

I figured the 5.3.5 image would be a good start for a docker-host(small footprint, awesome thermals) but it seems that its missing the support for overlayfs in the kernel. The batman-adv module is another requirement. I looked into rebuilding the kernel myself but I'm quite unclear about the directions and the codebases/patches/configs used to create the supplied image&kernel. I can produce new kernels but I run into issues like missing wifi and the like.

Happy about any info shedding some light on how to successfully rebuild/recreate the v24+ kernels!

P.S.: I found https://github.com/avafinger/linux-5.6.y and tickered with it but it seems I'm missing something there, too. No clue.

Cheers

You should start with this configuration, disable lima and lower CMA. And add support for docker and the likes. https://github.com/avafinger/linux-5.6.y/blob/master/arch/arm/configs/m2z_lima_defconfig
