Arch Linux User Repository

IMPORTANT NOTICE

Intel has announced that they are shutting the Clear Linux distribution, which includes the Linux kernel patches that this package relies on. This means that we (JeremyStarTM and yarost12) won't be able to update the linux-clear package anymore.

To avoid this, we have decided to fork the Clear Linux kernel patchset and want to continue updating it for newer kernel versions. Unfortunately, we both will not be able to maintain that patchset alone and require help from others. If anyone has experience with kernel development and wants to help out, please contribute! If we don't manage to get enough developers on board, we might need to kill the package, which we definitely want to avoid.

The fork can be found here: https://git.staropensource.de/StarOpenSource/Linux-Tachyon

(this message can also be found when installing or updating the package)

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
- _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.

I think it would be helpful to get some descriptions on those kernel parameters. What do they do and why are they usefull to have. I know some of them like - quiet, rootfstype and rw - but I'm unfamiliar with the rest.

I understand. Thank you.

@Tjuh That's because of gcc10 in testing repo that you're using? You can check in arch linux's repo all the commits related to gcc10 warnings.
Clear Linux still uses gcc9 so we'll see when they'll update that.

No problem with previous iteration, but this one fails.

@metak I see, thanks. @lucasrizzini thanks.

@rvlobato As @lucasrizzini has said, you can easily add that patch and build it for your self. I removed fsync patch because clear team don't feel comfortable enough to include it.

No. You have to patch the source manually. Just add "patch -Np1 -i /path/to/patch/file" just below "### Add Clearlinux patches" around line #108.

Patch -> https://git.covolunablu.org/portaloffreedom/linux-covolunablu-gaming/blob/master/futex-wait-multiple-5.2.1.patch

Hello, is fsync still working on linux-clear?

@metak Thanks.

@AliTajelsir Hi. You can ignore that warning. https://wiki.archlinux.org/index.php/Makepkg#WARNING:_Package_contains_reference_to_$srcdir
objtool file contains some path references to where the package was built. Regular arch kernel should have that too.
