Beschreibung
Zusammenfassung:	A voltage regulator phase shedding system includes one or more subsystems to receive a system management interrupt (SMI), gather processor utilization information, determine whether to adjust a performance state, lookup voltage regulator information for new performance state, adjust active voltage regulator phase, and adjust performance state. The voltage regulator phase shedding system can also include one or more subsystems to read a power measurement, calculate throttling requirements, determine whether to adjust a throttling, lookup voltage regulator information for new performance state capacity, adjust active voltage regulator phase, and adjust throttling.
