Anyone have tried to do something similar?
no but anyway - freebsd halts CPU when unused, even at full frequency
it uses very little power wne unused.
Really? Good to know. I was wondering if I could make this laptop of
mine a bit cooler, but then I guess not.
I also believe that the CPU is actually halted when idle but using
powerd brings the temperatures on my machine still down. As powerd can
be adjusted in which interval it adjusts the CPU frequency, short tasks
run actually at the minimum frequency if the CPU was idle.
The negative side effect is, that a click takes some time before the
machine really starts to react if the expected action results in more
computing.
