Getting Debian Kernel Config for 5.4 LTS Kernel

[Janis Hamme <lists.oss@hamme.info>]

Hi,

I'd like to build the vanilla 5.4.69 LTS Kernel for one of my Debian
machines (Buster).

The easiest way seems to build the Kernel with the built in "make
deb-pkg" target. Since I do not really want to go through all the config
changes,
my plan was to get a 5.4 config for amd64 from
https://salsa.debian.org/kernel-team/linux

I cloned the git repository and checked out the 5.4.19-1_bpo10+1 tag.
But the config seems do be manged somehow by the Debian build system and
is split across multiple files for different architectures and feature
sets etc. Does someone know how I can generate the final amd64 config to
use it for my custom kernel?

Updating the Debian package sources for 5.4.69 would also work. It
probably easy, but I didn't find any documentation or tutorials on it (I
also don't really want to deal with the Debian custom patches that
probably won't apply properly to Vanilla 5.4.69)

Regards
Janis
