Hi Nico, Liviu, Catalin,

Do you expect there to also be cases where the PSCI interface may
not be aware of all of the platform states?

Eg. if you have an SOC, not all of the cstates and latencies are
directly related to the ARM core.. Maybe you can have
additional states and latencies accounting for the cost of
enabling external power supplies, restoring state for
non-retained peripherals/hw, etc.

Currently, this type of thing can be specified in cpuidle with
aditional cstates and handled in vendor specific sw, with the
additional cstates being selected when the TR/latency requirements
are least restrictive.

How would these states be handled considering also host os costs?

Thanks,

Sebastian
