Greetings. I saw this post about building kernel for stoney but it’s for debian. I’m very new to Linux and am using Arch linux (largely to learn this all vigorously).
A step-by-step guide would be most appreciated but general guidance (reference to verified guides, etc) would also help
The arch wiki has a general guide for compiling your own kernel. Make sure you modify the PKGBUILD to include the patch file linked in the post you referenced.
(also, I am new to forum-style stuff so let me if I am not providing enough info or giving irrelevant info, and thanks WeirdTreeThing for the guidance initially)
Why are you trying to use Liquorix on Arch? Arch Wiki page linked by WTT already has all required commands to get sources for your kernel and how to add patches.
Ahh… So Liquorix is not a patch? Since it was part of the post itself, I thought it was also a patch (or, more specifically, the patch inside zen folder in the patches) hence why I added it in the patches
May you kindly provide me with all the required patches? I wish to avoid making this kind of stupid mistake again
I am also interested in which patch should be applied to a stock kernel for archlinux.
For other kernel packages (e.g. stock Debian kernel) and other distros, you’ll need to manually apply all of the following patches
and there are two patches, one is for kernel <6.15 and the second for >6.16. I downloaded stock 6.17.7 from kernel.org and tried to apply the patch for kernel >6.16, but it appeared that the patch was already applied.
Question: Do I need to apply the patch for <6.15 too? @WeirdTreeThing ?
Take commit 43de1b163dc572dc4061c9baf005216e3ce11348 from archlinux kernel package , put amd-gpu.patch in the root dir and add amd-gpu.patch to the sources in PKGBUILD. Or simply use PKGBUILD below:
