Aside from the whole PM_OPP question; you should assert that assumption. Put an explicit check for the uarch in and FAIL the init if that isn't met. I don't think it makes _ANY_ kind of sense to share a frequency domain across uarchs and we should be very clear we're not going to support anything like that. I know DynamiQ strictly speaking allows that, but since it's insane, we should consider that a bug in DynamiQ.
