ubilinux and PREEMPT_RT kernel support

machinekodermachinekoder Posts: 8New Member

It would be great if ubilinux would support a PREEMPT_RT patched kernel. Upstream Debian comes with an RT kernel, so it wouldn't be hard to compile one for ubilinux as well.

I'm also willing to do this myself. Can you please confirm that these instructions work for ubilinux: https://wiki.up-community.org/Compile_ubilinux_kernel_from_source

Also, which kernel patch version is the current is the kernel on branch upboard-4.9? So I can select the correct RT patch.

    The kernel is 4.9.65, and I've used those instructions without issues.

    Hi @machinekoder ,

    The instructions are working properly for Ubilinux kernel.

    Thanks, the instructions work great to build a kernel for upstream Debian:

    uname -a
    Linux upsquared 4.9.45-rt57-upboard-rt+ #1 SMP PREEMPT RT Thu Aug 9 12:02:41 CEST 2018 x86_64 GNU/Linux

    Applying the RT patches worked perfectly, I only had to manually modify one file afterward.

    @Jesse Kaukonen The pach level seems to be 4.9.45 in my case.

    Great machinekoder!

    Can you share a link to the source code/configuration on github so we could add to the wiki?
