I am hoping someone could help me find out some stuff about apm with linux. I have a desktop system that spends a lot of time with the cpu idle, and i'm interested in getting apm setup to save some power during these times. I have a supermicro motherboard with ami bios that supports apm, but I'm not sure which of the several options in the kernel to enable and which of the several options in the bios to enable to get the desired effect.
I did get apm to function, but it wasn't the way i wanted. I set an inactivity timeout in the bios and after that period of time, the cpu did indeed downshift. *However*, when the cpu became non-inactive, the bios did not speed the cpu up. Apparently, the bios was simply monitoring things like key presses to determine inactivity. I would like to set it up so that the kernel decides when it is inactive and when it is not. That way, when left unattended, the cpu could slow down and speed up according to cpu demand (since there is a great deal of unattended activity) and not simply user interaction at the console.
This type of setup may not be possible. The ami bios documentation is very terse and I find even less documentation for the linux side.
Can anyone help me?
Thanks, Erv
