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

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 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.

@metak it looks like this issue will be fixed in LVM2. I'm not sure why it only affects me on linux-clear, though...

@aorth Seems like this issue is already reported upstream. LVM Clearlinux takes a long time to shut down

@metak yeah I saw that thread. They seem to conclude that it's something related to LVM, and I am indeed using LVM on LUKS, though for me the issue only happens on linux-clear. The screen is black with a blinking cursor and eventually (maybe 90 seconds, I should actually time it) it says something about failing to unmount oldroot and then it reboots.

Edit: thanks @metak. I won't spam here anymore. Nice to know I'm not alone and that someone has even reported it upstream. For reference, here is the message that is spammed after the cursor blinks for ~90 seconds and it finally reboots:

[  116.123456] sd-umoun[1040]: Failed to unmount /oldroot: Device or resource busy
[  116.123456] sd-umoun[1041]: Failed to unmount /oldroot/dev: Device or resource busy
[  117.123457] reboot: Restarting system

@aorth Have you checked this thread? https://www.reddit.com/r/archlinux/comments/b6hbca/need_some_help_figuring_out_why_my_system_hangs/

Does anyone get a blinking cursor for about one minute on shutdown? It's the one annoying thing that causes me to stop running linux-clear. Not sure if it's a systemd job waiting or something...

@ltsdw Thanx. Seems like it's already fixed by clear team in 5.0.1-716.

@metak done!

@ltsdw Can you please report this issue upstream?

This was enabled on the config by the clear's devs, but this is causing a error message on boot:

kvm: already loaded the other module

According to gentoo's documentation this is due to both intel and amd kvm module beeing enabled on the kernel compiling CONFIG_KVM_AMD and CONFIG_KVM_INTEL:

https://wiki.gentoo.org/wiki/QEMU#.22kvm:_already_loaded_the_other_module.22

Recompiling the kernel only with respective module for my processor resolved problem. In my case CONFIG_KVM_INTEL

@phantomas 1. The upstream patches failed to apply because you tried to re-build the package without cleaning the src dir.
2. That part of the pkgbuild file is taken from linux-ck package. Every custom kernel in aur pretty much has it the same. I guess if you wanted you could change the line to yes "" | make localmodconfig for defaults.
