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.

@metak - Oh I see, adding SigLevel = Optional for now. Thanks!

@eca Hi, yes OBS (open build service) just recently added support for zstd packages in arch and the part that generates the signatures wasn't yet updated. ISSUE REPORT

But, on the other hand the signatures for pacman in OBS are broken since a long time ago so there's that... if you look a page or two back in the comments you'll find my explanation.

@metak - I think your repo is missing pgpsigs. error: linux-clear: missing required signature.

@metak - the config and compile optimizations will be great addition. Please introduce them. Thanks.

@idimitro Well, I can add -j$(nproc) to make command, but _subarch backup is beyond the scope of this package. That's up to user.

@metak - if possible please extract the config. The kernel config is one part of the customizations. Other things that can be extracted are: arch selection "_subarch=" and "make -j8 bzImage modules" (allow multithread compilation as it currently compiles in single core). The end target is to have the package build automatically + customizations with aurto :)

@abdulocracy For i915 module, that's builtin with this kernel.

cat /lib/modules/$(uname -r)/modules.builtin | grep i915

kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko
kernel/drivers/gpu/drm/i915/i915.ko

Edit: let me check some more about that error...

@idimitro For now the pkgbuild just copies the .config file for archival purposes and you can't easily reuse it later. If it would be useful I might add support for reusing the old file just like it is in linux-lqx package? Check Here.

I'm getting these errors on a i7-8550U machine, upon sleeping and resuming:

Jan 09 09:05:05 abdulkadir-xps kernel: [drm:intel_power_domains_verify_state] *ERROR* power well DC off state mismatch (refcount 0/enabled 1)
Jan 09 09:05:05 abdulkadir-xps kernel: DMAR: DRHD: handling fault status reg 2
Jan 09 09:05:05 abdulkadir-xps kernel: DMAR: [INTR-REMAP] Request device [f0:1f.0] fault index 0 [fault reason 37] Blocked a compatibility format interrupt request

Also, the second console option in the upstream cmdline causes my machine to boot to a black screen.

Edit: Another peculiarity, modinfo -p i915 states that the module was not found.

Hi, the PKGBUILD file has options to optimize the kernel for the specific machine it will run. But how are those changes supposed to be preserved after upgrades? I couldn't find an option for the configs to be read from the outside the build directory. Any suggestions?
