Hi,
I'm using small ITX board with VIA C7 Esther processor as file server (FreeNas embedded, built on FreeBSD 7.3). Server is running 7x24h and power consumption is a problem. Unfortunately FreeNas doesn't support ACPI S1 and S3. Powerd is enabled and working almost fine. Frequency is scalling just fine (lower dev.cpu.0.freq: 124), but problem is with processor vcore voltage, isn't reduced when system is idle. (still 1.01 V).
Another problem is cpufreq and EST support for VIA C7 processors with embedded PowerSaver technology (similar to Intel SpeedStep).
Currently freq. levels shows:
What does -1 mean?
I found only info about supporting by EST driver VIA C7-M processors (C7 is very similar). Somebody of you know something about FreeBSD support for PowerSaver technology?
