Custom kernel versions #44

|
How are we supposed to set custom kernel versions when using rpi-nix? I would like to run a newer version that has in-tree support for bcachefs (kernel 6.7+), but I realize that this project sets the kernel version for me. Is there a way I can get a newer kernel version without breaking my system? I guess another question would be if it's possible to use the official (non-rpi foundation) linux kernels on my pi with or without this project. Edit: I found an option called |

Yes, I expect that your edit would work. You also don't need to override the input, but can instead add to the This project is arranged to support multiple kernel/board versions (see here), so a PR to add 6.11 as a kernel option that tracks the rpi linux branch would also be accepted.
This is possible, with various levels of success. You will find plenty of threads about it on the nixpkgs issue tracker. This project is focused on stability and full hardware support, and hence uses the raspberry pi linux fork. So, this repo without the rpi linux fork doesn't make much sense. |

Oh, and two other things,
If I wanted to do this, would I just set kernelPackages like how I do it on other systems?
I see. I guess you mean issues like NixOS/nixpkgs#300328, NixOS/nixpkgs#142848, NixOS/nixpkgs#82455, and NixOS/nixpkgs#97064? (Web search for "nixpkgs raspberry pi kernel issue".) A lot of mentions of bit failures. I guess that does sound pretty sketchy. I was hoping it would just be stuff like graphics bugs since my rpi is headless 🫠 |
