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.

@adsoncicilioti you need to patch the kernel for nvidia_uvm to work

use this if you want

Hi @metak! nice work with Clear Kernel. I'm using the 5.9.6 from your repo, and all boot parms requireds by Clear, including module.sig_unenforce.

With standard and Zen Kernel, all nvidia modules are loaded correctly - nvidia, nvidia_drm, nvidia_modset, nvidia_uvm. On clear nvidia_uvm module not is loaded, and apps like blender, and other that uses CUDA cores, not recognize the nvidia (cuda device).

I've try with # modprobe nvidia_uvm command but the error is returned: modprobe: ERROR: could not insert 'nvidia_uvm': Unknown symbol in module, or unknown parameter (see dmesg).

Running dmesg i got:

  184.986139] nvidia_uvm: module uses symbols from proprietary module nvidia, inheriting taint.
[  184.986268] nvidia_uvm: Unknown symbol radix_tree_preloads (err -2)

I've don't understand why the standard and zen Kernels loads and Clear not. Any idea?

@krathalan I can change that with next update.

@metak some users (like myself) may have their ~/.config/modprobed.db file actually be a symlink to somewhere else that is shared with other systems. You should change the -f on line 215 from if [ -f $HOME/.config/modprobed.db ]; then to -e, so it reads if [ -e $HOME/.config/modprobed.db ]; then.

From man test, -f checks that: FILE exists and is a regular file (emphasis mine). -e only checks that: FILE exists. -f returns false if the file exists but is a symlink.

So once I've built the kernel with my customized config options from nconfig, I see the config file is copied into the main directory. How do I use this when I want to recompile again, or when the kernel updates and there are more config options (like make oldconfig would show you)?

Thanks, metak!

@enihcam Change urls, remove patches and configs added in this package that you don't need. Comment out the Patch0129 otherwise the build will fail.

@metak, I need patches from https://github.com/clearlinux-pkgs/linux-hyperv instead. Can I just grab your PKGBUILD and change few URLs? what else should I change?

@Gonzo2028 Works fine on my end. Please try building with makepkg instead of aur helpers and clean your build directory first.

@Tjuh Well that's up to clear team to update first. The -current & -preempt-rt are both updated to latest clear versions 5.8.0.rc7 & 5.6.19.rt11 - upstream.
5.9rc1 was released and clear team will probably update their -current soon to it.

Plese update current and preempt-rt versions.
