@Eirikr I'll take a look at that. It should not be missing iwlwifi. I use Intel WiFi on my work laptop afaik.
Eirikr commented on 2023-05-07 17:09 (UTC)
Is iwlwifi missing from the regular linux-nitrous as well?
I run with kernel option mitigations=off but I think this disables further mitigations if I’m not mistaken… and allows for undervolting in combination with the right UEFI firmware version on hardware that had it disabled.
Really would prefer though to use my internal wireless instead of a USB stick
(Can’t install iwlwifi-next or any other version either… all give error 7 during kernel module installation even after using CC=clang and CXX=clang++ in both /etc/makepkg.conf and /etc/environment)

@Technetium1 thank you. I've updated the PKGBUILD and it will be available upon next release.

Missing lzop
in makedepends
to build in clean chroot.

i have problem to install this kernel with nvidia module, these module cannot install

@tam1m Perfect, that's great. Thanks for letting me know.
tam1m commented on 2021-09-10 16:51 (UTC)
@superboringdev Yes, this works! Thank you!

@tam1m
Thank you for explaining and providing a patch! I applied the patch. Please test if it works for you.

@superboringdev
Thank you! But in order for this to really work, there are some more changes needed. I looked through the code of mkinitcpio and booster and found, that both of them come with install/remove hooks for kernel packages.
They both look for usr/lib/modules/*/vmlinuz
on install/remove/upgrade and execute their respective scripts, which generate the initramfs images and copy vmlinuz
to /boot
. Dracut doesn't come with any pacman hooks itself, but the wiki describes how to set those up and these are working the same way. Also systemd seems to expect this (see https://github.com/systemd/systemd/commit/edda44605f06a41fb86b7ab8128dcf99161d2344) .It also seems to be expected, that there is a usr/lib/modules/*/pkgbase
which just holds the content if $pkgbase
(in this case linux-nitrous-fire
).
Setup like this, the initramfs generators will do all the work from copying vmlinuz
to /boot
to generating the initramfs and the reverse on uninstall. I tested this with mkinitcpio and booster and it seems to work nicely. I don't have dracut setup, but it should work aswell.
Here is a small patch with the changes need for PKGBUILD
and linux-nitrous-fire.install
.

Note that this is not a secure kernel. It has things disabled that mitigate security bugs in the processor (for example retpoline, spectre/meltdown mitigation etc.) and some things tuned here and there. Do not use this on servers or on machines where security is important.
It looks like not many people are using this and thus the binary packages are not going to be available anymore. This will need to be built from source.
Update: Because this kernel is insecure, untested and barely used, it won't be updated anymore. Use linux-nitrous instead.
