CPU frequency governors and remote callbacks
CPU frequency governors and remote callbacks

The kernel's CPU-frequency ("cpufreq") governors are charged with picking an operating frequency for each processor that minimizes power use while maintaining an adequate level of performance as determined by the current policy. These governors normally run locally, with each CPU handling its own frequency management. The 4.14 kernel release, though, will enable the CPU-frequency governors to control the frequency of any CPU in the system if the architecture permits, a change that should improve the performance of the system overall.
