Great news! I just tested the code in git on my macbook air. (4,1) A few remarks on usability and some questions: On startup for the first time, powertop says: Cannot load from file /var/cache/powertop/saved_results.powertop Cannot load from file /var/cache/powertop/saved_parameters.powertop which is expected, I guess. I'd suggest adding: 'Creating it.' Although saved_parameters.powertop *isn't* created, unless I 'touch' it first? 'powertop --calibrate' requires access to :0, and powertop does not complain if/when a laptop is plugged into AC. The intended users of powertop easily understands these things and remedies them. Others may be slightly confused I guess. 'powertop --calibrate' dims the panel. And I waited a looong while for it to come back on. I finally gave up and increased brightness, just to see powertop running in its regular mode. I assume DPMS kicked in somewhere. :-) Depending on what you want to measure, it may be an idea to disable DPMS, or maybe just wake up the panel when the calibration loop is done? Not sure what is doable, and how difficult it is. Perhaps this works exactly as you want it? The calibrating backlight thing... how is that affected if DPMS is active? As I said, my panel went dark. I can't tell if powertop actually adjusted the backlight during calibration. At the end of the calibration run, powertop states: Score: 90.9 (1950924.6) Guess: 100.2 Actual: 6.8 Care to enlighten me as to what this means? dmesg tells me: ieee80211 phy0: brcms_ops_config: change power-save mode: false (implement) This is clearly unrelated to powertop, but I wonder if this actually means that the driver for my wifi card is missing power management?
