Important update
I have updated and renamed some settings envvars. Please check your scripts, aliases, brain memory or whatever you use to store your build command and update them accordingly. Please read the description in the PKGBUILD file instead of the short summary in the pinned comment on the AUR or in the README in the repository as some important details important to this update are only found inside the PKGBUILD.

Information comment
This comment provides useful information about this package. Make sure to read it through, you won't regret it.

Repository URL
This package is hosted at sos!git. If you want to contribute to the package, you can do it here: https://git.staropensource.de/JeremyStarTM/aur-linux-clear

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
- _reuse_current: Will use the configuration of the running kernel, if the running kernel is compiled with IKCONFIG_PROC
- _reuse_file: Will use the configuration file named kconfig contained in the PKGBUILD file's directory
- _update_kconfig_on_reuse: Specifies whether the kernel configuration shall be updated when using any of the 'reuse*' flags
- _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 (Generic x86-64), which is compatible with all amd64 processors. Must be a number
- _use_llvm_lto: Enables compilation with LLVM. Untested but should work. If not write a comment on the AUR.
- _subarch_microarch: Specifies the microarchitecture to compile for. Only applies to and is required by the GENERIC_CPU subarch. Must be a number between 1 and 4 (click for more information)
- _debug_kernel: Force enables kernel debugging options when set to y, force disables debug options when set to n or relies on the kconfig when unset
- _debug_script: Enables debugging for the PKGBUILD file

All of these variables just need to be set for them to apply, except for _subarch, _subarch_microarch and _debug_kernel. 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.

Kernel has been updated and is now maintained again.

Thank you metak for creating this package in the first place.

Hi everyone. After metak announced that he had orphaned the package I decided to continue maintaining it. I will begin updating the package in a few days.

Hi everyone. So, recently I bought a new pc with amd ryzen cpu and I 'll no longer maintain any of the -clear linux kernel packages. There's also my regular job and lack of time.

I'm orphaning this and all the other -clear packages for someone else to adopt. It's been five years since first commit. ;-)

d.e: I don't really know what you are meaning with "config changes [...] are not carried over". All config settings should be applied as make nconfig is the last statement executed in prepare() that is modifying the kernel configuration

But that "overwriting kernel-config options permanently" I can help you with. I am maintaining a personal fork of this package at https://git.staropensource.de/JeremyStarTM/kernel-optimized. Just pass the env variable _copyfinalconfig=y to the PKGBUILD or answer y in the handy buildtool.sh script. After the build completes, execute `mv kconfig-final kconfig" to replace the repository's kernel config with your own. From now on, your kernel config will be used for each future build.

Alternatively, you could modify the PKGBUILD and add that functionality to your own.

I hope that helps ;)

I would like to add kernel module signing, therefore I am following this article. - Would it be possible to integrate the required changes into the PKGBUILD file, maybe?

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

Thank you for the hint. - I have used that, but the config changes done by _makenconfig are not carried over. It is as if I didnt edit the config at all.

I have used _subarch to specify the architecture type, but I have to do that every time.

Is there a possibility to have a config file, where I can add options like _subarch permanently, and also overwrite permanently some kernel-config options?

Some permanent options would be very plesant to have.

d.e: You can modify the kernel config and the subarch by setting "_makenconfig" and "_subarch".

This is a good start, but I would like to be able to set some default .config options, without having to fiddle manually with the package. - Is that somehow possible?

Specifically I want to enable Landlock and Lockdown mode.

Also I have not found a way to set the _subarch by default. - Is there a way to preconfigure such options?

ls-alh: That's weird behaviour. I'm using the normal tmpfs size and it compiles without error. Maybe your tmpfs is filled with stuff before even starting the compilation process, try checking /tmp before compiling. Otherwise I don't know what could be causing this.
