Good news! #OpenBSD -current now allows setting a separate performance policy (hw.perfpolicy) when on battery power vs. on AC power.

This is useful as a few years ago the default changed. The "auto" performance policy (hw.perfpolicy) is equivalent to "high" on when on AC power and there was no option to change this without custom kernel patches, or a userspace solution (sysutils/obsdfreqd).

jca@ modified src/sys/kern/sched_bsd.c: Let the user provide an alternative perfpolicy when on battery

The current behavior of "auto", which implies running at full speed when on AC power, does not fit all the hardware and use cases. For some people it results in more power consumption, more heat, more noise, etc.

Extend the semantics of hw.perfpolicy and provide two buttons to specify the desired behavior:

sysctl hw.perfpolicy=ac-policy,battery-policy

Keep the default behavior of "high,auto". People can opt for "auto,auto" or simply "auto" instead.

No objection from deraadt@, input and ok sobrado@ sthen@

@sullybiker btw "no one has ever seen before" includes by me. I never saw more than 1 percent of what I'm showing here in a form other than a postage-stamp sized image on a proof sheet until I started scanning the negatives.

is there a good comparison of the server resources required for running different #activitypub servers somewhere? i'm interested mostly in cpu, ram and network traffic
