Compile linux-aarch64 with CONFIG_PREEMPT

Postby tuxx » Thu Dec 12, 2019 7:23 am

Hi all,

I have been using linux-aarch64 on my odroid C2 for a long time now. I noticed that instead of CONFIG_PREEMPT this package is being built with CONFIG_PREEMPT_VOLUNTARY.

Is there any chance so that the official package comes with CONFIG_PREEMPT?

I haven't compiled lately with this option, but I've done in previous versions without any issues at all.

Thank you in advance.

Greetings,

MIke

I compiled and tested the latest kernel with CONFIG_PREEMPT.

I forked the repo and submitted the modified kernel config (forgetting however to calculate the new sums and put them on the PKGBUILD):

https://github.com/archlinuxarm/PKGBUIL ... 2886211221

It was immediately rejected without any comment. I assume that ArchlinuxARM devs had their reasons to do so, but unfortunately I will never learn. :D

You should start learning by researching things yourself. The rules for contributing are all over the forum and github. Any decent project on github will have "CONTRIBUTING.md" file that contains the rules for contributing.

Even if you followed the rules, I don't think this change would be accepted anyway because CONFIG_PREEMPT_VOLUNTARY is a good compromise between server and desktop workloads.

Moonman,

Thanks for your reply.

Lesson learned and next pull request will be less messy.

This is a current division of ArchlinuxARM kernels based on preemption:

To sum up, I believe that my request is reasonable, unless aarch64 is known to have issues with the module I suggested.
