WebIntel P-state implements the setpolicy() callback. The driver decides what P-state to use based on the policy requested from the cpufreq core. If the processor is capable of selecting its next P-state internally, the driver offloads this responsibility to the processor. If not, the driver implements algorithms to select the next P-state.
