Proposal update
The package has been updated to 6.11.7 (clr 6.11.6-1477), and with that landlock support has been enabled the package source moved to https://git.staropensource.de/JeremyStarTM/linux-clear.

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.

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
_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 write a comment
_subarch: Specifies the sub architecture to compile for (see the PKGBUILD file for a list of all subarches). Default is 40 (Generic-x86-64), which is compatible with all amd64 processors. Must be a number
_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. See their descriptions for more information.

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.

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. Tihs prevents unnecessary signups.

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.

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.

Building linux-clear has been failing since 6.8.10 due to filling up /tmp directory. I haven't changed anything about compiling between past successes and new failings. Since failures, I've tried increasing /tmp space from 5.8 GiB to 10 GiB to no avail. It still fills up. I don't use modprobed-db to reduce compile time/space. My system is otherwise up-to-date. Can someone help me debug this?

EDIT: After a successful git clone and `BUILDDIR=/Storage/tmp _subarch=24 makepkg', my otherwise empty /Storage/tmp is now 20GiB...

@odpuck

You need to install modprobed-db from air start the service and then when your compiling a kernel run as root modprobed-db command to load the list of modules to be used, also you have to modify PKBUILD a bit to be ready to accept modprobed.

I built this kernel a million times using modprobe and it only takes 10 minutes tops
