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
_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 write a comment
_subarch: Specifies the sub architecture to compile for (see the PKGBUILD file for a list of all subarches). Default is 41 (GENERIC_CPU), compatible with all amd64 processors. Must be a number
_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: 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.

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.

Package no longer asks to select subarch, it just goes with the default. If do export _subarch=42 (to select Intel native) and then usual paru it still invokes gcc with -march=core2

KrisKorn: The package is designed to be built with your own kernel configuration, we do not ship one. You can supply one by renaming your .config file to kconfig and placing it next to the PKGBUILD file. If you want, you can set _copyfinalconfig to get your updated kconfig back.

I had two different problems:

1) I couldn't start virtualbox because the kvm module was set as built-in and not as a module. VirtualBox needs it to be a module to be able to remove it since it doesn't use it. The way to solve this was to enable the "${_makexconfig:="y"}" option and change the KVM option from there.

2) I also had to resort to makexconfig to disable NUMA support. I have a desktop computer that doesn't use NUMA so I thought I'd disable it. It would be nice to have the option to disable NUMA in the PKGBUILD file.

Thanks!

xoita: That is actually intended behaviour. This package will likely be built by regular users which have a working tty and therefore stdin. That's why it asks you if it is left blank. If automation or different behaviour is wanted, one can pass custom envvars. That's why they are there. Hope that explained it a bit.

Still have the same problem when trying to build without changing any of the variables. Stops at:

Processor family
  ...
  17. Intel Atom (MATOM)
> 18. Intel Core 2 (MCORE2)
  19. Intel Nehalem (MNEHALEM) (NEW)
  ...
choice[1-43?]: 

When I set _subarch=41 _subarch_microarch=1, build continues as expected. Maybe _subarch should be explicitly set instead of left blank?

xiota: fixed the issues. you can now supply the _subarch_microarch envvar. must be number between 1 to 4, defaults to 1. see this for more info

I'm trying to build this on a headless server, and build gets stuck waiting for input to select architecture. Also, indicated default for architecture is not generic, as noted in package comment.

if you need ps4/ps5 controller support you need to add:

scripts/config -m LEDS_CLASS_MULTICOLOR
scripts/config -m HID_PLAYSTATION
scripts/config -e PLAYSTATION_FF

to PKGBUILD

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.
