aur-linux-clear/README.md

# linux-clear
This repository contains the `PKGBUILD` file required for building the `linux-clear` and `linux-clear-headers` packages.
You can find this package [on the AUR](https://aur.archlinux.org/pkgbase/linux-clear).

## How to build and install
[Read this Arch Linux Wiki article.](https://wiki.archlinux.org/title/Arch_User_Repository)

## Updates
This package is usually updated 0-3 days after a kernel release.
If a security-relevant update is available the package will be updated as soon as possible.

## Environment variables
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 sub architecture to compile for (see the [PKGBUILD file](https://git.staropensource.de/JeremyStarTM/aur-linux-clear/src/branch/develop/PKGBUILD) for a list of all subarches). Default is `41` (Generic x86-64), which is compatible with all amd64 processors. Must be a number
- `_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:
```bash
gpg --locate-keys torvalds@kernel.org gregkh@kernel.org sashal@kernel.org benhh@debian.org
```
This command only needs to be executed once.

## Issue handling
Please only submit issues if they aren't bug reports about the package or help requests.
Please keep them on the AUR only. This prevents unnecessary signups.

## License
This package does not yet have a license as the original repository (before [me](https://git.staropensource.de/JeremyStarTM) becoming it's maintainer) did not have one yet.
I have contacted [metak](https://aur.archlinux.org/account/metak) (the previous maintainer) to negotiate a license.

## Build tool
*If you want a dead simple way to compile this package, you can [try out my build tool](https://git.staropensource.de/JeremyStarTM/jstm-optimized). It includes a few no nonsense changes to the kernel configuration and allows you to configure the PKGBUILD in a simple manner to decrease build time. If you don't want that, using `makepkg` as-is works fine too.*
