Hi David,

in all my use-cases I always know what is the CPU I am dealing with and
what are the C-states. Simply because in my view they are always CPU-
dependent in terms of what they do and how are they named.

What you say sounds to me like you would want to disable some C-states
without knowing anything (or much) about the CPU you are dealing with
and the C-state names.

If so, could you please share examples of such use-cases?

Thanks!
