目前我只知道LFM,EPP,perf-bias
epp_override是第二种EPP状态?动态调节?

- # Energy Performance Preference.

- # Conveys a hint to the HWP hardware. The OS may write a range of values from 0 (performance preference) to 0FFH (energy efficiency preference)
- # to influence the rate of performance increase / decrease and the result of the hardware's energy efficiency and performance optimizations. The
- # default value of this field is 80H.
- #
- # Note: If CPUID.06H:EAX[bit 10] indicates that this field is not supported, HWP uses the value of the IA32_ENERGY_PERF_BIAS MSR (perf-bias) to
- # determine the energy efficiency / performance preference.
- # 00~94 00是最接近高性能的值,94是最接近省电的值,建议desktop用20,laptop用80
