Linux-hardened + hibernation

12 September 2022, 15:13:22

Hi everyone,

I have an installation of Artix-OpenRC w/ the Linux-hardened kernel on a partially encrypted (unencrypted /boot partition) drive. I am trying to set up hibernation, since it's not supported by default (I chose the linux-hardened kernel since it's the recommended option in the guide). How do I do it? There is this package in the AUR, but it seems to be broken as of today.

Reading this article, I presume one has to build a custom kernel. Will these instructions also work for Artix? Do some of you (who maybe achieved the same thing) have some recommendations?

Thanks

UPDATE:

I managed to retrieve the linux-hardened kernel source code via asp:

Code: [Select]

asp update linux-hardened
asp export linux-hardened

Then, I modified config to enable hibernation (uncomment CONFIG_HIBERNATION) and applied this patch to PKGBUILD:

Code: [Select]

diff --git a/trunk/PKGBUILD b/trunk/PKGBUILD

After that, I managed to update the checksums and my kernel is now compiling. I have one question: since I follow an Arch-related procedure, I was wondering if there may be incompatibilities due to the fact that I'm using Artix. May be a stupid question, but I'm pretty new to this. Since I retrieved the source through asp on a machine running Artix (i.e. with /etc/pacman.conf including the Artix repos), there should be no issue... But please, correct me if I'm wrong.
