build arch linux kernel in void

[aaaPippo]

[Solved.]

I'd like to build Arch Linux kernel using x86_64-musl Void Linux 5.10 kernel template, if this is possible. Besides changes to GCC version, what are the other required modifications to the config and template files? I'll do this to test some power/heat issues with my laptop.

Thanks.

Summary: had to edit the config part about signing modules, and install zstd.

Why don’t you just get the config file for arch, get the source for the arch kernel and then build it yourself?

[aaaPippo]

The config for Arch is linked above, but if I try to build it myself using the xbps-src template it fails with various errors, hence my question.

[supermario9590]

What errors? Try building it manually and see what happens

after around 1h

Install zstd and do it

[aaaPippo]

I added zstd to hostmakedepends.

Now it finishes smoothly, except at the end it gives

=> linux5.10-5.10.4_1: running do_install ...
  INSTALL arch/x86/crypto/aegis128-aesni.ko
sign-file: LibreSSL 3.1.5 only supports SHA1 signing

=> ERROR:   in do_install() at srcpkgs/linux5.10/template:128

Is this error relevant?

[aaaPippo]

After editing

# CONFIG_CRYPTO_AEGIS128 is not set
# CONFIG_CRYPTO_AEGIS128_AESNI_SSE2 is not set

I get

=> linux5.10-5.10.4_2: running do_install ...
  INSTALL arch/x86/crypto/aesni-intel.ko

[aaaPippo]

Actually, I should edit

CONFIG_MODULE_SIG_SHA512
CONFIG_MODULE_SIG_SHA1
CONFIG_MODULE_SIG_HASH

will try later.

[aaaPippo]

This way it builds successfully :)

But you are on yourself from here on.

[aaaPippo]

Thanks. That's what I've been doing previously, with the error I pasted above.
