Sorry for the delay - got pre-empted by other stuff. I took a look at
the per device constraints. Do I understand it correctly that the idea
is that there is only one constraint per device? If we want to make
frequency and latency per CPU I guess we'd need separate constraints
associated with the CPU device. Or do I misunderstand something?
Or would global CPU frequency be more in line with global CPU latency
after all?
