Modified existing PKGBUILD for current linux-rc

Yesterday, I compiled an rc linux kernel for testing.  Linux Arch2024p8 6.13.5-rc2 #1 SMP PREEMPT_DYNAMIC Tue Feb 25 20:25:29 PST 2025 x86_64 GNU/Linux

This kernel seems to have the patches applied that fix the AMD Raven series APU's. https://git.kernel.org/pub/scm/linux/ke … nux-6.13.y

15 hours    Linux 6.13.5-rc2linux-6.13.y    Greg Kroah-Hartman                                          1    -2/+2
15 hours    drm/amdgpu: bump version for RV/PCO compute fix    Alex Deucher           1    -1/+2
15 hours    drm/amdgpu/gfx9: manually control gfxoff for CS on RV    Alex Deucher     1    -2/+30

I used this as a guide: https://wiki.archlinux.org/title/Kernel … ompilation
And installed the kernel and modules manually, outside pacman, all seems well and it's stayed running overnight without freezing...

However, I thought a cleaner approach would be to have it installed via a pacman package, and what better opportunity to familiarize myself more with PKGBUILD's.
I'd also consider rolling with this kernel through the rc stage and making the process easier would be key to keeping up.

I found a 'linux-rc' AUR package, however it seemed to be on a static version of an old kernel.
I edited the PKGBUILD to build the version I'm currently running, however there's one small issue that required manual intervention.

Edit:  TLDR: The kernel source is comprised of a directory with all the required contents. Problem is the directory is named: linux-stable-rc-linux-6.13.y
I need it to be named: linux-6.13.5-rc2

So makepkg stopped on an error pointing out the missing directory, I renamed it in the src directory, and currently in process building.

What would be the best way to fix this?
I know the kernel config can be set to manually name the kernel, and I used the config of the latest Arch 'linux' package, which is set to auto name it.
I think from going through a kernel build manually, that I can either rename the dir, or possibly leave it as is and set the config to rename it.

If the PKGBUILD was a script, I wouldn't be here asking, but AFAIK, the PKGBUILD is processed by pacman makepkg, so I couldn't script the changes in the PKGBUILD.

Here's the edited PKGBUILD:

This was an incorrect assumption on my part. After a bit of tinkering, seems it's (executed/sourced?) as bash script after all.

Re: Modified existing PKGBUILD for current linux-rc

@scimmia these are the release candidates for the stable series (see for example https://lore.kernel.org/all/20250225064 … ation.org) and contain the not-yet-released changes for the stable series https://kernel.googlesource.com/pub/scm … ueue-6.13/

I have a PKGBUILD that I use to built these, I could publish it somewhere if that helps, but I also publish prebuilt versions of the kernels to my public html:

sudo pacman -U https://pkgbuild.com/\~gromit/linux-bisection-kernels/linux-6.13.5rc1-1-x86_64.pkg.tar.zst

Re: Modified existing PKGBUILD for current linux-rc

Very cool gromit!
Do you keep up with the rc bumps as well?
What about the bisect, is it modified from the stable-rc's?
Maybe a link to the PKGBUILD?
Are you re-building on patches or from scratch for each rc release?

Also, I'd still like to know how to fix the issue for potential future usage....

Re: Modified existing PKGBUILD for current linux-rc

No the bisect PKGBUILD is a modified version of the "linux" package that has docs removed and is switched to git sources (pinned to a specific commit) and has a pkgver() so that I can use images that I have already built smile

Re: Modified existing PKGBUILD for current linux-rc

I ended up putting this in the beginning of the 'prepare()' function to rename the root directory. 

dirname=$(find "${srcdir}"/ -maxdepth 1 -type d -name 'linux-stable*' -printf "%f\n")
	cd "${srcdir}"
	mv "${dirname}" "${pkgbase}"

After cleaning up this PKGBUILD a bit, I think may have possibly been better off starting with the repo 'linux' PKGBUILD. Seems this one is setup for some easy to edit options that I'll likely never use or investigate. I probably should go through the depends and makedepends arrays as well, to see if any packages are being pulled in for CLANG LLVM builds that aren't needed for GCC.

Interested in any constructive feedback on the renaming base directory and the latest changes:

Did you try renaming the download through source array ?

man PKGBUILD wrote:

source (array)
....
It is also possible to change the name of the downloaded file, which is helpful with weird URLs and for handling multiple source files with the same name. The syntax is: source=('filename::url').

(It does work with VCS urls.)

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Thanks for the reminder... Not sure why I skipped that but maybe because I was more in the 'bash scripting' mindset.
I don't see why 'filename::url' wouldn't work, although have not tested it yet.

I got sidetracked into trying to automate fetching the latest 'linux-stable-rc' version number in the PKGBUILD, without taking a very long time with git.
Still haven't figured out a good way to do this, and without it I don't see any point in moving forward on this.

That and our core testing repo moved 6.13.5 in yesterday, which is the one I've been waiting for.

I thought it would have been nice to have an AUR package with the latest 'linux-stable-rc' kernel + our patches applied.

You may be overthinking this. No need to 'automate' anything. And you can name it anything you'd like.

For a given kernel branch (currently linux-6.13.y), the tip/head will always point to the latest RC (currently Linux 6.13.5-rc2).

Whether you choose to pull via git or source the archive locally with filename::url is up to you.

The typical use-cases for running an RC kernel are to see if changes might fix an issue you're facing or to be a guinea pig for upstream testing in general.

In either case, the Arch patches are largely unnecessary unless they address something specifically affecting you.

It's easy enough to selectively apply any desired Arch patches on top of either method of sourcing. You may need to rebase them tho if you're ahead of the next tagged Arch release.

Re: Modified existing PKGBUILD for current linux-rc

OK, I've learned quite a bit going through this process so far. Unfortunately I'm still not getting along at all with the PKGBUILD 'pkeger()' function. No matter what I tried, it would auto detect a version somewhere in the source code? And exit on error complaining of how the 'pkgver' cannot have these characters, which it did not have.

I believe the issue is, makepkg doesn't like the version string upstream uses for this kernel, so I make the following change to it with a wrapper script. It seemed to make no difference what the 'pkgver' and 'pkgrel' were when I was trying to use the pkeger()' function.

Linux version          : 6.13.5-rc2
PKGBUILD version : 6.13.5rc-2

I was going into the source and temp editing files (Makefile and others) directly before and after the 'pkeger()' function ran, and still luck. I guess if an upstream project doesn't follow makepkg's versioning rules, you either can't use it on arch or I'm just too dumb to figure it out how to do it properly... lol

That said I'm pretty sure it's the latter, so I'm here to learn. . .

I also have a working PKGBUILD that runs normally, but it's 100% reliant on filtering the kernel.org 'web.git' for the version, and I just couldn't bring myself to post it on the forums and ask for help.

So I guess this is an improvement? The wrapper script I made takes a peek inside the source archive to get the version info, and then applies it to the PKGBUILD reformatted to it's liking. How might I use this in the PKGBUILD?

Here's what I have at this point.

The wrapper:

#!/bin/bash

_version=$(curl -s "https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/" |
	awk '/[0-9]-rc[0-9].*Greg/{match($0, /[0-9]+\.[0-9]+\.[0-9]+-rc[0-9]+/); if (RLENGTH) print substr($0, RSTART, RLENGTH)}' |
	sort -V |
	tail -n 1)


if	[[ ! -e linux-stable-rc-linux-6.13.y.tar.gz ]]; then
	wget https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/snapshot/linux-stable-rc-linux-"${_version%.*}".y.tar.gz
	# wget https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/snapshot/linux-stable-rc-linux-6.13.y.tar.gz
fi

_verst=$(_vdata='linux-stable-rc-linux-6.13.y.tar.gz'
	tar -xzOf "${_vdata}" "${_vdata%.tar*}"/Makefile | awk -F'= *' '
		/^VERS/ {v1 = $2}
		/^PATC/ {v2 = $2}
		/^SUBL/ {v3 = $2}
		/^EXTR/ {v4 = $2}
	END {print v1 "." v2 "." v3 v4}
	')

pkgver="${_verst%-rc*}rc"	# 6.13.5rc
pkgrel="${_verst#*-rc*}"	# 2

	echo "Linux version: ${_verst}"
	echo "Arch version : ${_verst%-rc*}rc-${_verst#*-rc*}"

if	grep -q pkgver=TBD PKGBUILD; then
	sed -i s/pkgver=TBD/pkgver="${pkgver}"/g PKGBUILD
fi
if	grep -q pkgrel=0 PKGBUILD; then	
	sed -i s/pkgrel=0/pkgrel="${pkgrel}"/g PKGBUILD
fi

	makepkg -sr

TLDR:

How can I use the code in my wrapper script, in the 'pkgver()' function?

Is there a way to gain more control of the PKGBUILD such as function order, etc?

@Lone_Wolf Your suggestion will rename the archive I'm downloading. However I needed to rename the extracted root directory.

@tekstryder, would git be the right tool for the job of downloading the archived kernel source? The kernel.org git.web has a download link, but filtering it out to use is far from ideal. In my limited time playing around, there is a huge time element in some operations involving the git repos.
