Issue handling
Please only submit issues in the package's repository if they aren't bug reports about the package or help requests. Please keep them to the AUR only. This prevents unnecessary signups.

Updates
I usually publish updates 0-3 days after a kernel release, depending on how busy I am.
If I however get wind of security-relevant updates or any vulnerabilities I will try to update the kernel as soon as possible and write a comment about the vulnerability/update. So make sure to subscribe to this package's comment mailing list.

PKGBUILD environment variable customization
The PKGBUILD file supports customization via environment variables. Here's a list of all of them:
- _makemenuconfig: Invokes make menuconfig (ncurses-based default configuration menu) before compilation starts
- _makenconfig: Invokes make nconfig (ncurses-based nicer configuration menu) before compilation starts
- _makexconfig: Invokes make xconfig (X11-based GUI configuration menu) before compilation starts
- _use_current: Will use the configuration of the running kernel, if the running kernel is compiled with IKCONFIG_PROC
- _optimize_defconfig: Applies package maintainer-picked configuration changes to your defconfig. Only takes effect with _use_current being enabled
- _copyfinalconfig: Copies the final kernel configuration into the repository root as kconfig-new before compilation starts
- _localmodcfg: Only compiles modules found in modprobed-db's database (which decreases compilation time and kernel size)
- _use_llvm_lto: Compiles the kernel with LLVM instead of GCC. Should work, if not open an issue
- _subarch: Specifies the subarchitecture to compile for (see the PKGBUILD file for a list of all subarches). Default is 41/MGENERIC_CPU (Generic x86-64), which is compatible with all amd64 processors. Must be a number or subarch name
- _subarch_microarch: Specifies the microarchitecture to compile for. Only applies to and is required by the MGENERIC_CPU subarch. Must be a number between 1 and 4 (click for more information)
- _debug: Force enables debug options when set to y, force disables debug options when set to n or uses the config defaults when unset

All of these variables just need to be set for them to apply, except for _subarch and _debug. For more information please check their documentation inside the PKGBUILD file

GPG errors
If makepkg complains about invalid PGP keys, try running this command first: gpg --locate-keys torvalds@kernel.org gregkh@kernel.org sashal@kernel.org benh@debian.org. This command only needs to be executed once.

Build tool
If you want a dead simple way to compile this package, you can try out my build tool. It includes a few no nonsense changes to the kernel configuration and allows you to configure the PKGBUILD file in a simple manner and decrease build time. And if you don't want that, using makepkg as-is works fine too.

I've done similar to following to apply saved changes to packages across updates.

#!/usr/bin/env bash

mv PKGBUILD PKGBUILD.orig

cat > PKGBUILD.append << END
eval "_update_defconfig() {
  # [[ insert new commands here ]]
  $(declare -f _update_defconfig | tail -n +3)"
END

cat > PKGBUILD << END
source PKGBUILD.orig
source PKGBUILD.append

sources+=('PKGBUILD.orig' 'PKGBUILD.append')
sha256sums+=('SKIP' 'SKIP')
END

snotabile: Hey, sorry for replying so late, I forgot to read my mails. The PKGBUILD actually modifiers the kernel configuration in the _update_defconfig method on line 319. Maybe you can slot in your own command in there to enable SCHED_EXT?

See here: https://git.staropensource.de/JeremyStarTM/aur-linux-clear/src/commit/272e8186915ef3542d9bc2b714cd1505f9c100c1/PKGBUILD#L319

Is there a way to enable the support to SCHED_EXT through the modification of the PKGBUILD file?

johneri: It may be beneficial if you could provide some dmesg output (if possible), provide information about your hardware or other useful things. I may not necessarily be able to help you, but others may. Also if your system freezes after a while but SysRQ is still working it may be an issue in your rendering stack.

on my system, it randomly freezes after 10 minutes or potentially as long as several hours, and i have to magic sysrq it otherwise, does anyone else have this problem?

Redefa: unfortunately no. But you can use the binary packages provided by the Chaotic AUR repository, which includes this package.

Will there be a pre-compiled version?

The _show_compile setting has been deprecated, please remove it from any scripts that y'all might have

xoita: Already noticed that yesterday when I was in bed, was too tired to fix it. Did it today, sorry for the small inconvenience.
