Following the Arch wiki, I built a custom kernel for the first time ever. It was easier that I thought it’d be, probably because the Arch wiki is so thorough and because I didn’t make that many changes… I just enabled a few FireWire related options as per this guide in order to work on this project (or this).
Results/takeaways
- The OS ran fine with the new kernel 💃
- I learned how to manually create GRUB entries 🔧
- I learned that I don’t even have to create new GRUB entries, since I can simply point to the new kernel image and initramfs from the bootloader menu 🪛
- I learned that my 5800X3D runs well (compiles the new kernel blazingly fast) with all cores set to negative 30 in the UEFI
- FireWire is dead 💀
Tiny followup on that project
That old GPU did something to the UEFI (possibly CMOS?), because even after removing all potentially incompatible hardware and reinstalling my modern GPU, I still got that same error message, saying that the system was forces to boot in CSM mode. Only by resetting the UEFI settings was I able to restore the system to a working state. I admit, I panicked.
Congrats!.. now do the whole system. 😁
Sorry for the late response!
Oh NO 🤣 I did successully install Gentoo once and I see the benefits. I really do. BUT. My brain works in such a way, that I need to understand every single USE flag, otherwise I “can’t” install packages 😭 I simply can’t allow myself to do a… “as is” installation with Gentoo… And I don’t have to motivation right now to learn EVERYTHING I’d have to learn xD
Sorry, short answer: yes, later xD
gentoo taught me how to recompile and it feels like arch takes that thunder sometimes. lol
In times of pre-optimized repos (like CachyOS) it seems rather redundant from a performance perspective. Other reasons remain valid though (learning or specialized optimizations or requirements).
Alternatively, it can also be considered wasteful (electricity/compute) when everyone compiles their whole system instead of doing it once in a central server.
