'man cpufreq' isn't much help in that regard either. In what way does powerd not work for you? ([EMAIL PROTECTED])$grep powerd /etc/defaults/rc.conf powerd_enable="NO" # Run powerd to lower our power usage. powerd_flags="" # Flags to powerd (if enabled).
read man powerd for flags and try powerd -v this should give an indication of what happens, for example I get [EMAIL PROTECTED] -v idle time > 90%, decreasing clock speed from 1666 MHz to 1457 MHz idle time > 90%, decreasing clock speed from 1457 MHz to 1249 MHz idle time > 90%, decreasing clock speed from 1249 MHz to 1041 MHz idle time > 90%, decreasing clock speed from 1041 MHz to 833 MHz idle time > 90%, decreasing clock speed from 833 MHz to 624 MHz idle time > 90%, decreasing clock speed from 624 MHz to 416 MHz idle time > 90%, decreasing clock speed from 416 MHz to 208 MHz idle time < 65%, increasing clock speed from 208 MHz to 624 MHz idle time > 90%, decreasing clock speed from 624 MHz to 416 MHz idle time > 90%, decreasing clock speed from 416 MHz to 208 MHz idle time < 65%, increasing clock speed from 208 MHz to 624 MHz idle time > 90%, decreasing clock speed from 624 MHz to 416 MHz which is a pain if i'm running X on mains so I tend to use -a maximum -b adaptive as my powerd flags as it defaults to adaptive even if your on mains power. > > Do I need working acpi to use a power control method? Umm not sure as mine works, but probably, since my dmesg says I have acpi_throttle0: <ACPI CPU Throttling> [EMAIL PROTECTED] | grep -i cpu CPU: Genuine Intel(R) CPU T2300 @ 1.66GHz (1662.51-MHz 686-class CPU) FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu0: <ACPI CPU> on acpi0 acpi_throttle0: <ACPI CPU Throttling> on cpu0 cpu1: <ACPI CPU> on acpi0 acpi_throttle1: <ACPI CPU Throttling> on cpu1 SMP: AP CPU #1 Launched!
