Description
Reads or changes the CPU energy-versus-performance bias setting exposed by Intel processors through MSR_IA32_ENERGY_PERF_BIAS. It is useful for administrators tuning power use, heat, noise, or performance policy on supported hardware.
This is a low-level hardware tuning tool. Changing model-specific registers can affect performance, battery life, thermals, and stability, so users should understand the CPU and test settings carefully.
