How to maintain kernel-source packages on OBS?
by Shung-Hsi Yu 27 Jun '24

Hi, I'm looking into maintaining a kernel based on out-of-tree patchset[1] on the openSUSE's build service (OBS) with Fredrik. While I work with kernel-source regularly, I have no idea on the process or publish/release the kernel. From the openSUSE:Kernel git[2] documentation and my understanding it goes down to: git clone https://github.com/openSUSE/kernel-source/ cd kernel-source git checkout $BRANCH # stable or master # Do some work here ... # Create source package scripts/tar-up.sh # Upload to OBS, need --enable-debug here otherwise BTF won't be # available scripts/osc_wrapper upload --enable-debug $PROJECT Once built, user should be able add the OBS repo, and install the kernel package I suppose? Or is there any additional that has to be done on the OBS project? Also there's two kernel branch I'd be working with: scx-kernel-releases[3] which is based on the latest stable, and sched_ext[4] which is based on bpf-next[5]. And it would be great to have suggestion on how to maintain them in practice within kernel-source. Since scx-kernel-releases is based on stable, it seems rather straight forward to maintain. I'd fork from the kernel-source's stable branch, add another directory (patches.sched-ext perhaps), add the patches there, modify series.conf to include the sched-ext patches so they are applied, and update the kernel configuration in config/ accordingly. After that it should be mostly just merging from kernel-source's stable as it changes, I hope. On the other hand sched_ext being based on the development branch bpf-next seems a bit more daunting. I could base off of kernel-source's master, but then I had to take all the patches in bpf-next[5] (which includes netdev/net-next[6]) in addition to sched-ext ones, and bpf-next could change rather often. Is there a better way to do this? Could I simply grab a tarball from the sched_ext GitHub repository[4] and use it instead? Or maybe it's just not worth the effort? Feedbacks, suggestions, and pros & cons are all welcome.

grub2 update problem by installing the new vanilla kernel from source
by Alexander Naumov 12 May '24

12 May '24

Hey, I'm trying to install the new vanilla kernel on tumbleweed. What I did: # zypper in gcc make ncurses-devel bison flex libelf-devel libopenssl-devel bc # make menuconfig # make -j4 # make modules_install # make install Everything fine, I get vmlinux (not vmlinuz), System.map, etc. In /boot I also have initrd. By trying to update grub2 (by running 'grub2-mkconfig') I don't get any errors (return code 0), everything looks fine, but after that the new kernel is not listed in the config file. Does anybody can tell me what I miss? I found a lot of documentation about SLE/openSUSE Kernel, but want to install new vanilla without any (open)SUSE-specific scripts, etc. Thank you. Cheers, Alex
