Not using this package myself, but the fact that it does not preconfigure the parallelism for the user is a Good thing.

For super heavy building tasks like compilers or kernels, you always want to configure the number of threads on a per-machine base. Just like on Gentoo.

Running too many threads can not only make your CPU slow, but it can also make memory usage seriously high (really just monitor it). If you forget to have made enough RAM or swap space available you'll end up with trouble.

may be update the config to stay more in line with current linux package? I see mainly CONFIG_PREEEMPT not set. and CONFIG_HZ_1000 too

Oh sorry about my ignorant question. Thank you for pointing me to the right direction. It took roughly one hour to build on my laptop. I’m glad I didn’t try with a single thread.

Make all your builds parallel with the instructions on the Arch Wiki makepkg page. Let me know if this PKGBUILD does anything to block parallel builds.

Is this build not parallelized? Why?

To get the signatures working, I ran this as myself (not root):

gpg2 --locate-keys torvalds@kernel.org gregkh@kernel.org

I got this command from here:

https://www.kernel.org/signature.html

Then it built fine (except for warnings mostly to do with documentation)

I get this error
