Why is there need for another tool?
CPU power consumption vs performance tuning is not about CPU frequency switching anymore for quite some time. Deep sleep states, traditional dynamic frequency scaling and hidden turbo/boost frequencies are tight close together and depend on each other. The first two exist on different architectures like PPC, Itanium and ARM the latter only on X86. On X86 the APU (CPU+GPU) will only run most efficiently if CPU and GPU has proper power management in place.
Users and Developers want to have *one* tool to get an overview what their system supports and to monitor and debug CPU power management in detail.
The tool should compile and work on as much architectures as possible.
Hi Thomas, Do you think handling really vendor specific "boosts" like EeePC's SHE is in cpupower scope ? Still, it would not solve the issue of setting SHE mode in a standard way, or associating it with a governor. Thanks,
