Using custom kernel (6.9.0)

Bluefin
1

To get audio working on Dell XPS 14, kernel 6.9.0 is needed at the moment as it has Intel MeteorLake chipset fixes.
This is related to [BUG] Audio not working on Dell XPS 14 (9440) with Cirrus Logic CS42L43 · Issue #4974 · thesofproject/linux · GitHub

Got this working on Silverblue, but on Bluefin running:

rpm-ostree override replace https://bodhi.fedoraproject.org/updates/FEDORA-2024-344431ca97

causes all sorts of conflicts and I can’t figure out how to replace/remove the old packages:

Anyone managed to replace the kernel on Bluefin? Not sure what I’m missing here…already tried many combinations of replace with --remove and --install

Hi there. Just curious, were you ever able to get this to work?

I was trying to install on Aurora a custom kernels I compiled:
sudo rpm-ostree override replace ./kernel*

And it returns this mess. Pretty much the same error as you’re having:

For anyone else having this issue, I’ve been informed that you’ll just have to create your own custom image. Installing a custom kernel is not supported.

This’ll get better in the future, they’re working on it now, it’ll look something like slide 32:

Only got it working on vanilla Silverblue as it doesn’t have these dependent modules. Also tried:

koji download-build --arch=$(uname -m) kernel-6.9.1-201.fc40
rpm-ostree override replace kernel-modules-core-6*.rpm kernel-core-6*.rpm kernel-modules-6*.rpm kernel-6*.rpm kernel-modules-extra-6*.rpm

but with similar effect.
Thanks for confirming it’s not supported at the moment. I guess I’ll just wait for the new kernel to be included.

Anyone happen to know if it is now possible to build and install custom kerrnels with bluefin (or bazzite?)?

I’m getting an Asus Flow Z13 (with the new Strix Halo APU in it) tomorrow - largely to get linux working nicely on it. I’m trying to select a distribution right now to do this work with.

From talking with the devs on asus-linux I think it is likely I’ll have to apply a few patches & do some development on the current 6.14 WIP kernel. I can handle that fine, but it is a long time since I last worked with an rpm based distribution. Even with that limitation I was still thinking about trying one of your new cool container targeted forks/layers/unclear-on-the-preferred-term. However, this thread makes me think universal-blue is not yet recommended if I want to just be able to build an image and reboot to try with new kernel/module changes?

I’ve done a fair amount of kernel development, but it was all for semi-closed source hardware products. I’ve never before futzed with this new ‘atomic’ layer fedora is describing. Would it be better for me to use old-school !atomic fedora till I get the kernel solid then afterwards deal with switching to something like bluefin to be my daily driver (with my fixed kernel)?
