I need an assistant to build a kernel with a patch from lore.kernel.or

I've reported a bug https://bugzilla.kernel.org/show_bug.cgi?id=218789 and looks like a fix is proposed.

To test it I need a custom kernel with this fix. I've tried to build a kernel few days ago, different patch for different bug and no luck.

I saw wiki page but in my case I need more detailed instruction lol. Can someone assist? Ideally to build it by myself.

https://wiki.archlinux.org/title/Arch_build_system

Just add the patch to the source array and add a patch step in the prepare function of the linux package.  Should be easy.

Well as I said I saw that wiki page and it doesn't help. lol And not easy

The start question what is patch in my case https://lore.kernel.org/linux-acpi/4926 … @kreacher/  Should I just copy a code from the link? Or manually modify files with changes. How to name the patch file if it's matter.

Well thanks for building a package for me.

I'm still want to solve the original question though. I have a few bugs to report and looks like every time I will stuck with this patches to be applies somehow

My edit came at the same time as you replied.  If that does not help, please provide more details about what went wrong when you built a custom kernel.

Re: I need an assistant to build a kernel with a patch from lore.kernel.or

The questions are:

1. here is a link to the patch   '4926735.31r3eYUQgx@kreacher.patch::https://lore.kernel.org/linux-acpi/4926735.31r3eYUQgx@kreacher/raw' how to draw it up? I see the first part is message id the second is the link. Is it always looks like this?
2. Where to get sha256sums and b2sums. Well I know how to get the sum for files within terminal. I mean how to get sums for particular patch? On what file I have to calculate it.
3. I got an error 

    linux-6.8.9.tar ... FAILED (unknown public key 38DBBDC86092693E)
    linux-v6.8.9-arch1.patch.zst ... FAILED (unknown public key B8AC08600F108CDF)
==> ERROR: One or more PGP signatures could not be verified!

The format above is needed when you want to rename a file locally.  Without the rename the file would be downloaded to 4926735.31r3eYUQgx@kreacher which does not have the .patch extension so would not automatically be applied by the PKGBUILD.

The checksums array entries match to the source array entries so you add it in the same position in that array as you add the patch in the sources array or use `makepkg -g >> PKGBUILD` or `updpkgsums`  as covered in step 2 of Applying_patches

Signing keys need to be in the keyring of the user running makepkg

gpg --import keys/pgp/*.asc
