No one knows, nor will they ever remember, what "atd_" means :(
Naming is hard, I know, here's my suggestion:

arch_cpu_normalize_capacity(); or cpu_normalize_capacity();
Why do you care if this is "arch" or not, of course it's arch-specific in a way, right?

cpu_parse_capacity();

cpu_scale_capacity();

wait, where did the cpu go? This doesn't make much sense, these are all "capacity" issues, right? If so, then these should be: capacity_normalize_cpu() capacity_parse_cpu() capacity_scale_cpu() capacity_set_scale()
But this is all really topology stuff, right? Why use "capacity" at all: topology_normalize_cpu() topology_parse_cpu() topology_scale_cpu() topology_set_scale() ?
It's always best to put the "subsystem" name first, we have a bad history of getting this wrong in the past by putting the verb first, not the noun.
thanks,
