Arch Linux User Repository

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.

Well something really weird, now I can't boot even to rescue with linux-clear. Logs are clean but laptop seems to get stuck at last stage.

@Osleg Yes, the easier choice is to not use initrd /intel-ucode.img (clr default), otherwise the build would fail and require some adjustments/patching.

Hm, I just realized that linux-clear also has ucode built in so we either should not initrd /intel-ucode.img or should not compile it with clear... I think first option is better to follow intel's kernel as close as possible.

@metak unfortunately I have no idea. The boot process goes well until the end and it stuck when starting to load graphical.target. I could boot into single user mode but that doesn't help in any way :/

And yay for the module.sig_unenforce, will try that... in recovery mode tho :(

@Osleg Do you have any idea what might be the problem? Btw, clr-team introduced new patch in their latest commit called Add boot option to allow unsigned modules so that's why I removed that sed line from pkgbuild.

+Add module.sig_unenforce boot parameter to allow loading unsigned kernel
 +modules. Parameter is only effective if CONFIG_MODULE_SIG_FORCE is
 +enabled and system is *not* SecureBooted.

https://github.com/clearlinux-pkgs/linux/commit/347ebb59a916a6fd112663d68e0b72623f6994f7

Just to be exact, it stopped working even before update back when it was 4.15.15

Have no idea what happened but the kernel stopped working for me. It reaches target graphical and then laptop hangs. :/

@Osleg I disabled CONFIG_MODULE_SIG_FORCE by default and if anyone wants to turn it on just comment that line in pkgbuild.

The main issue with modules not loading is that clear has CONFIG_MODULE_SIG and CONFIG_MODULE_SIG_FORCE enabled. Meaning most of the "custom" modules won't load. The workaround that I'm using for that is to sign those modules manually as described here https://www.kernel.org/doc/html/v4.10/admin-guide/module-signing.html

Tho I think it might be a good idea to disable CONFIG_MODULE_SIG_FORCE or at least provide a config for PKGBUILD to disable it for those who want. as this setting is good for hardened kernel for servers and such. For desktop machines, especially for developers, this setting provides nothing but pain :)
