The function cpu_power_to_freq is used to find a frequency and set the cooling device to consume at most the power to be converted. For example, if the power to be converted is 80mW, and the em table is as follow. struct em_cap_state table[] = { /* KHz mW */ { 1008000, 36, 0 }, { 1200000, 49, 0 }, { 1296000, 59, 0 }, { 1416000, 72, 0 }, { 1512000, 86, 0 }, }; The target frequency should be 1416000KHz, not 1512000KHz.
