merde, of course you can have full lscpu or whatever you want!!
Thanks, indeed.
(I was only sad because of that AMD "territorial pissing" as via
  lid_exists() {
        if [ -z "$LID" ]; then
                # Documentation/firmware-guide/acpi/acpi-lid.rst
                LID=/proc/acpi/button/lid/LID0/state
                [ -f "$LID" ] && return 0
                # amd ryzen 5 220, linux 6.18
                LID=/proc/acpi/button/lid/LID/state
                [ -f "$LID" ] && return 0
                LID=.
        fi
        [ "$LID" != . ]
  }
Cool that really someone deals with bugzilla!!!)
