If not, would it make any sense to patch >speedstep-centrino to use this feature too? I'm a little confused. How is this different from the ACPI CPU throttling states (/proc/acpi/processor/CPUn/limit to set, throttling to see all T-states available)? On my 1.5-year-old Pentium-M, frequency scaling and T-states are different beasties, and act entirely differently. I'm currently in the process of rewriting my governor's brain to deal with the two more intelligently. -Joseph -- Joseph===============================================trelane@digitasaru.net Graduate Student in Physics, Freelance Free Software Developer
