Generic Scaling GovernorsCPUFreq provides generic scaling governors that can be used with all scaling drivers. As stated before, each of them implements a single, possibly parametrized, performance scaling algorithm. Scaling governors are attached to policy objects and different policy objects can be handled by different scaling governors at the same time (although that may lead to suboptimal results in some cases). The scaling governor for a given policy object can be changed at any time with t ...
