    I guess the official doc you guys are looking for is the x86-64 ABI:

    https://gitlab.com/x86-psABIs/x86-64-ABI/

    and recent pdfs are here:

    https://gitlab.com/x86-psABIs/x86-64-ABI/-/wikis/x86-64-psABI

    and there you scroll to

    "A.2 AMD64 Linux Kernel Conventions

    ...

    A.2.1 Calling Conventions"

    and that section explains which regs go where.

    HTH.
