Description Rene Schickbauer 2009-07-05 17:10:00 UTC
This patch enables users to use the powerd adaptive modes while still maintaining a cooler/less power hungry system by limiting the max. CPU speed powerd can set.

This patch also includes an update to the powerd manpage. I also moved the description of the available modes to a dedicated section to make them easier to find.

I wrote this patch, to limit my EEE PC's power consumption/heat production without having to fall back to minimum performance.

Fix: See attached patch

Patch attached with submission follows:
How-To-Repeat: Run an Intel Atom based NetBook with powerd set to "adaptive" and "make buildworld". It gets hot enough to get you burned when held in hand or lap (like when debugging FreeBSD while waiting for the bus).
Comment 1 Rene Schickbauer 2009-07-20 14:17:49 UTC
Here is an updated patch that allows setting of minimum and maximum speeds.
Seperately for battery and AC mode, of course.

I also updated the man-page.

(Hope i didn't mess this follow-up up, gnats doesn't like my webmail)
