Right. You don't need to scale capacity to determine whether a cpu is
full or not if you don't have DVFS, but I don't think it hurts if it is
done right. We need the scaling to figure out how much capacity is
available.

Maybe I'm particularly dense, but I'm not seeing how the proposed thing
is 'right' in any way.

There are no words on what specifically is addressed and how it is
achieved.
