Zusammenfassung:A method and apparatus for load step, or instantaneous current spike, mitigation are provided. In the method and apparatus, load steps are mitigated if a computer system a whole is lightly load, which may be determined by the power consumption of the computer system. Further, load steps are mitigated if a number of processor cores capable of inducing a load step is higher than a threshold. The Advanced Configuration and Power Interface (ACPI) performance state of the cores is used to determine a core's potential for generating a load step. A processor core is instructed to mitigate load steps if conditions are met for the mitigation.
