The PKGBUILD file supports a few different configurable build-time options:

• _makenconfig Tweak kernel options prior to a build via nconfig. Pseudo-graphical menu based on ncurses. 1 2
• _localmodcfg Only compile active modules to VASTLY reduce the number of modules built and the build time.
• Please read arch wiki page for detailed explanation on how to use it.
• _subarch Enable additional optimization/tuning for kernel builds by adding more micro-architectures options. Default is Generic-x86-64 number 36 if nothing else is selected.
• PKGBUILD file with the list of architectures
• graysky kernel_compiler_patch
• _use_current Use the current kernel's .config file. Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults. Useful when the package gets updated and you already went through the trouble of customizing your config options. NOT recommended when a new kernel is released, but again, convenient for package bumps.
• _use_llvm_lto Compile the kernel with LLVM/Clang.
• _debug Enable y some additional debug features present in arch kernel, but not in Clear upstream. n to force disable or leave empty to ignore.

Lastly, build the kernel by setting your environment variable env _subarch=40 _localmodcfg=y.

1. Binaries available in my repo: http://download.opensuse.org/repositories/home:/metakcahura:/kernel/Arch_Extra_standard/x86_64/

[home_metakcahura_kernel_Arch_Extra_standard]
SigLevel = Never
Server = http://download.opensuse.org/repositories/home:/metakcahura:/kernel/Arch_Extra_standard/$arch

THIS IS OPTIONAL:

2. After install adjust your boot cmd line. ClearLinux uses clr-boot-manager which takes care of that. This is upstream default:

quiet console=tty0 console=ttyS0,115200n8 cryptomgr.notests initcall_debug intel_iommu=igfx_off kvm-intel.nested=1 no_timer_check noreplace-smp page_alloc.shuffle=1 rcupdate.rcu_expedited=1 rootfstype=ext4,btrfs,xfs,f2fs tsc=reliable rw 

@metak thank you

@Ahmedtas I don't really know... There are opened issues asking this same question on their github page, but without answer. Their other kernel packages are definitely lagging behind, -current, -preempt-rt,... Maybe they have other more important things to do / test? 5.10 is LTS anyway.

Just a question: Why there isn't version 5.11 or 5.12 ?

@olace & @xuanruiqi It's a problem with new version of file. https://bbs.archlinux.org/viewtopic.php?id=265115

For some reason it seems that makepkg doesn't extract non-tarball compressed files automatically anymore....

I'm unfortunately having the same problem as @olace.

Hi, could help with these?

@amoka Workaround is what it is right now where I just removed it from boot cmd line because it's completely optional. init-rdahead clear srpm package provides initra-desktop and it reads ahead list of libraries/files on boot I believe.

It seems that we don't have this file in Arch initra-desktop and Clear Linux cmdline adds: init=/usr/bin/initra-desktop. Any workarounds for this in Arch?
