Arch Linux User Repository

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 

Now ok... Thanks :-)

@Athemis Sorry about that, fixed now. I basically have three slightly different pkgbuild files to update (local, aur, and obs for binaries)... ;-)

Thanks for keeping this up to date! However, 4.17.1 fails to compile for me, unless I change $_clearver to 27b762cf009a56fa47e00660d602f9db4b672ffb.

@gaougalos That's expected if you're building this kernel on top of the default arch kernel since all those config options are not present in default clear .config but are in stock arch.

When i enable localmodconfig it returns

As of 4.16.14-1 I've added kernel_gcc_optimizations patch. Disabled by default. Try and report any issues.

make[1]: *** Nessuna regola per generare l'obiettivo "firmware/intel-ucode/06-4f-01", necessario per "firmware/intel-ucode/06-4f-01.gen.o". Arresto.

@Osleg Moved acpi_rev_override as a choice. As for those additional patches, I don't know, this kernel is meant for newer intel skylake processors...

@metak I'm not sure it should be enabled by default as this is rarely used. Tho on the other hand vanilla kernel has it enabled so I don't know which approach would be better. imho tho providing prompts to enable/disable features like it happens in linux-ck, including the -mnative builds requested below would be the best option to allow every user to chose the options he needs the most.
