Hi all,

There used to be a -C switch for apm/apmd for "cool" mode, where the
automatic performance adjustment mode would throttle down CPU
frequency regardless of AC power status.

Currently auto mode goes to highest frequency (+turbo) while on AC
power, this is good when connected to mains at room temperature, but
not so great in hotter climates and/or while connected to a power
bank.

Is there any appetite to perhaps introduce a new hw.perfpolicy=battery
or similar to retain the same mode as auto with no AC power?

Looking at sys/kern/sched_bsd.c this should be a fairly trivial change.

Any thoughts?

Thanks,
PT
