Re/ powerd I have in /etc/rc.conf: # powerd powerd_enable="YES" powerd_flags="-a max -b adp" # performance_cx_lowest="Cmax" economy_cx_lowest="Cmax" (and the additional hint.* in /boot/loader.conf as well). Which process 'performance_cx_lowest' and 'economy_cx_lowest' target exactly as config values?
