You may want to try tuning its default modes/idle/busy settings, and measure real power used at different freqs. I suggest trying the advice there to disable p4tcc and acpi_throttle, reducing number of P-states considerably. Then 'service powerd stop', run powerd -v in a console and measure power consumption at various loads and CPU frequencies. If you have no wattmeter, acpiconf -i0 may serve as a guide (though you do have to wait a while for changes to be reflected); for such monitoring (albeit with working acpi_ibm) I use: smithi on t23% cat ~/bin/t23stat #!/bin/sh echo -n "`date` " sysctl dev.cpu.0.freq dev.cpu.0.cx_usage sysctl dev.acpi_ibm | egrep 'fan_|thermal' sysctl hw.acpi.thermal.tz0.temperature acpiconf -i0 | egrep 'State|Remain|Present|Volt' smithi on t23% t23stat Mon Aug 19 22:09:15 EST 2013 dev.cpu.0.freq: 733 dev.cpu.0.cx_usage: 0.05% 99.94% 0.00% last 529us dev.acpi_ibm.0.fan_speed: 2254 dev.acpi_ibm.0.fan_level: 1 dev.acpi_ibm.0.thermal: 47 46 42 -1 -1 -1 29 -1 hw.acpi.thermal.tz0.temperature: 47.0C State: discharging Remaining capacity: 95% Remaining time: 2:36 Present rate: 17313 mW Present voltage: 12236 mV Cheers, Ian
