[snip] ok, how about this to start with: http://people.freebsd.org/~adrian/power/20140504-powerd-1.diff This defaults powerd to set minfreq to 50% of the hardware available maxfreq, unless minfreq is explicitly given on the command line. This should at least fix some of the really silly default decisions made by powerd during idle. This code sorely needs an update to the cpufreq_*() routines. That can come later. Does anyone have any issues? -a
