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.

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.

I have reverted the package to the previous, working version for the time being. I'll fix the package and make sure everything works before updating this package to the newest version. Again, I'm very sorry for my little incompetency in the past few days. I should've tested the updated, yet I did not. This is my fault, and I'm sorry for the current situation.

6.11.3-3 does not boot.

noitemstoshow: thanks for the correction... again. I unfortunately didn't have enough time to test the changes, although I should've done that. I'll from now on compile the kernel first and then update the package. I'm sorry for the trouble in the past few days :P

Thank you for the update. on the line 266 of PKGBUILD file, it should be now

more-ISA-levels-and-uarches-for-kernel-6.8-rc4+.patch

instead of

more-uarches-for-kernel-6.8-rc4+.patch

after this correction, it built fine (with LTO enabled, zen3).

To build with LTO enabled, would need to install clang, lld, and llvm

ZhangHua: Thanks for catching and reporting! I unfortunately didn't have the time yet to compile the kernel myself, othehrwise I would've noticed it. Fixed it in the latest commit, should work now :)

It seems that you forgot to update https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=linux-clear#n124

Which results that makepkg tries to find 6.11.12-1472, which is not exist in git tags. There is only tag 6.11.3-1472.

Thanks.

noitemstoshow: Simply put amd_pstate=active into your kernel command line. That should do it. For more information read this Reddit post.

is there a way/config to have the other scaling driver like amd_pstate_epp made while compiling this kernel mod? amd_pstate_epp seems to give more states and can have lower freq while idle.

Update on the 9.9 vulnerability: It seems to affect CUPS and not the kernel. A fix is out already but has not yet landed in Arch's repositories. Make sure to update your systems as soon as it's out. Disable cups-browsed by executing systemctl disable --now cups-browsed in your terminal in the meantime.
