By the way, what does /-1 mean, in > dev.cpu.0.freq_levels output? The second value is power in milliwatts, the first is frequency in Mhz. If you have only throttling support, there's no way to know what the power consumption is so -1 is "unknown". If you have both throttling and some other driver that knows the power consumption, these values will be accurate. -- Nate
