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 

enabling CONFIG_NET_VENDOR_AQUANTIA worked for me.

@Gonzo2028 Hi. I've enabled CONFIG_NET_VENDOR_AQUANTIA, does that work for you or do you need me to also build the atlantic module?

Found CONFIG_NET_VENDOR_AQUANTIA is disabled in config. Compiling and then testing...

My new 10GBE Ethernet card seems to not work with that kernel. It hangs on boot. Any ideas? Stock kernel works fine.

@Gonzo2028 You can check in the kernel config file in /proc/config.gz at # Processor type and features section.

zcat /proc/config.gz > /tmp/config-$(uname -r)

Thanks! I will give it a try. Is there a method to read the used subarch on compilation for the current running kernel?

@Gonzo2028 You just have to make a small change to pkgbuild file, set _subarch=13 for zen3 and point the source for gcc optimizations patch to latest commit to get the required patch.

or just tell me how to implement znver3 then ;). Thanks.

i have gcc 11 installed, i just need the option. or will native detect znver3 if available?

@Gonzo2028 Hi, znver3 requires gcc from trunk so I can't add that.
Add -march=znver3/requires gcc trunk at this time
