Description of problem: While looking for a tool which uses ACPI speed stepping I found that cpuspeed doesn't support this. Version-Release number of selected component (if applicable): cpuspeed-1.2.1-1.33 Additional info: I found a nice tool called "scaler" which does the job: http://users.utu.fi/~paemsu/scaler/ It uses /proc/acpi/processor/CPU0/throttling for selecting CPU speed. Can this code be implemented in "cpuspeed" as a fallback?
throttling != speed scaling, and most of the time, it's a really bad idea. The upstream ACPI maintainers have also talked about removing this in future kernels, so adding things depending on it, is also a bad idea.
Ok, I understand, also I've connected a AC power meter and have to recognize, that throtteling won't save any power at all...so "scaler" is at least on this desktop PC useless.
