arm64 sys-kernel/gentoo-kernel questions

So far I have just used the kernel and parts from the then current RPiOS when setting up a Pi, or updating its kernel. I wasn't prepared to sort my way through configuring a kernel for the Pi, still not ready to. I had tried gentoo-kernel on an amd64 box for a while and it seems fine.

How is gentoo-kernel working for those of you using the arm64 variety?

I suppose

Code: Select all

root #cd /usr/src/linux
root #mount /boot
root #make -j4 Image modules dtbs
root #make modules_install dtbs_install

works.

Any input is welcome, thanks.

flysideways,

You will need to write a config.txt file as the Raspberry Pi firmware will not find the kernel or dtb installed by

Code: Select all

make install

I'm not sure if you get /boot/overlays like that either.

I've always cross compiled my kernel and installed it by hand.

I have my Gentoo booting from the usb. I have just booted the Pi from RPiOS on the sd card, made sure it was current, and copied the bits to the Gentoo usb drive.

I did build Gentoo a few times from Sakaki's guide but not in a long time. I have been doing everything natively for grins. I even set up a Pi distcc farm for a while. That was interesting but, well, just an exercise. I was sort of curious to gain experience as a user that had minimal hardware access, in order to have an opinion based upon actual experience.
