[SOLVED] Removing modules from initfs?

is it possible to REMOVE modules from autodetection on mkinitcpio?

I am following this line of reasoning https://hansdegoede.dreamwidth.org/28291.html and want to remove amdgpu from my initfs.

I didn't want to jump into dracut just now

I tried the obvious: unload the module before autodetection. but it doesn't do what i thought.

# mkinitcpio -M | grep thunder
thunderbolt
(i don't want to unload my display driver :)
# rmmod thunderbolt
# lsmod | grep thunderbolt
(nothing)
# mkinitcpio -M | grep thunder
thunderbolt

this https://blog.falconindy.com/articles/op … tcpio.html makes me believe that just removing hooks will solve the autodetection hook, but the wiki implies this actually reduces the list "Shrinks your initramfs to a smaller size by creating a whitelist of modules from a scan of sysfs."

Autodetect has nothing at all to do with your question. It removes modules not in use, that's all. It's the OTHER hooks that add the modules, take a look at the mkinitcpio wiki page to see what they all do, it should be pretty obvious what you want.

Re: [SOLVED] Removing modules from initfs?

indeed. `kms` hook does include it.

My main confusion was that while adding and removing kms hook, I was looking into logs, not cpio files.

But now it is even worse... I get the exact same log messages about amdgpu and drm being loaded at 2s into boot, before i even have root mounted! How the module loads without the module available?

...I don't know how to check compiled module into vmlinuz, but i think the changes are low amdgpu is there.
