Arch Linux User Repository

The PKGBUILD supports customization via environment variables. Here's a list of all of them:
_makemenuconfig: Invokes make menuconfig (default configuration menu) before compilation starts
_makenconfig: Invokes make nconfig (nicer configuration menu) before compilation starts
_makexconfig: Invokes make xconfig (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.

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 in a simple manner and decrease build time. And if you don't want that, using makepkg as-is works fine too.

Kernel has been updated and is now maintained again.

Thank you metak for creating this package in the first place.

@metak - if possible please extract the config. The kernel config is one part of the customizations. Other things that can be extracted are: arch selection "_subarch=" and "make -j8 bzImage modules" (allow multithread compilation as it currently compiles in single core). The end target is to have the package build automatically + customizations with aurto :)

@abdulocracy For i915 module, that's builtin with this kernel.

cat /lib/modules/$(uname -r)/modules.builtin | grep i915

kernel/drivers/gpu/drm/i915/gvt/kvmgt.ko
kernel/drivers/gpu/drm/i915/i915.ko

Edit: let me check some more about that error...

@idimitro For now the pkgbuild just copies the .config file for archival purposes and you can't easily reuse it later. If it would be useful I might add support for reusing the old file just like it is in linux-lqx package? Check Here.

I'm getting these errors on a i7-8550U machine, upon sleeping and resuming:

Jan 09 09:05:05 abdulkadir-xps kernel: [drm:intel_power_domains_verify_state] *ERROR* power well DC off state mismatch (refcount 0/enabled 1)
Jan 09 09:05:05 abdulkadir-xps kernel: DMAR: DRHD: handling fault status reg 2
Jan 09 09:05:05 abdulkadir-xps kernel: DMAR: [INTR-REMAP] Request device [f0:1f.0] fault index 0 [fault reason 37] Blocked a compatibility format interrupt request

Also, the second console option in the upstream cmdline causes my machine to boot to a black screen.

Edit: Another peculiarity, modinfo -p i915 states that the module was not found.

Hi, the PKGBUILD file has options to optimize the kernel for the specific machine it will run. But how are those changes supposed to be preserved after upgrades? I couldn't find an option for the configs to be read from the outside the build directory. Any suggestions?

@metak Works great! Thanks

@tam1m It's also reported on archlinux bug tracker. I've applied the patch from the bug repport in 5.4.3-2 if you can test it?

I'm experiencing this bug bug with linux-clear 5.4.2-1. The e1000e driver constantly crashes.

@danhyal I've added it, but if there's any complaints/regressions/etc. I'll have to remove it. So I hope you and others can test it and report back.

consider adding the fsync patch? https://aur.archlinux.org/cgit/aur.git/plain/futex-wait-multiple-5.2.1.patch?h=linux-fsync
