Proposal update
The package has been updated to 6.11.7 (clr 6.11.6-1477), and with that landlock support has been enabled the package source moved to https://git.staropensource.de/JeremyStarTM/linux-clear.

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

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.

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
_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 write a comment
_subarch: Specifies the sub architecture to compile for (see the PKGBUILD file for a list of all subarches). Default is 40 (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 first: gpg --locate-keys torvalds@kernel.org gregkh@kernel.org sashal@kernel.org benh@debian.org. This command only needs to be executed once.

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. Tihs prevents unnecessary signups.

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.

@fidasx That's because gcc10 is now default in arch.

I wasn't able to get nvidia-dkms working with linux-clear and gcc10. As a quick workaround, dowgrading to gcc9 and rebuilding linux-clear AND nvidia-dkms works. This however makes nvidia-dkms incompatible with every linux package compiled with gcc10 (default arch kernel for example). So keep that in mind

@metak

getting errors on nvidia-dkms driver for 5.6.13-1

WARNING: /var/lib/dkms/nvidia/440.82/build/nvidia.o(.text.unlikely+0x317): 
Section mismatch in reference from the function nv_module_init() to the 
function .init.text:nvlink_core_init()
The function nv_module_init() references
the function __init nvlink_core_init().
This is often because nv_module_init lacks a __init

any idea? have been using your kernel for a long time never had this problem

Great! Much obliged.

@Tjuh the documentation for kernel params can be found here:

https://www.kernel.org/doc/html/v5.6/admin-guide/kernel-parameters.html

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.
