So what do you need those INTEL_FAM6* defines for? I see peci_cpu_device_ids[] which are used to match the CPU so at least that thing must be loading on x86 hardware... reading your 0th message, it sounds like that peci-cpu thing is loaded on an x86 CPU and it then exposes those interfaces which a PECI controller accesses. And then I see in init_core_mask() the single usage of INTEL_FAM6* and that drivers/hwmon/peci/cputemp.c is a CPU temp monitoring client so that thing probably runs on x86 too. Or? If it does, then you don't need the code move. But it looks like I'm missing something... -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
