1. A voltage regulator control system comprising a single voltage regulator, the single voltage regulator communicatively coupled directly to each of a plurality of processors, the single voltage regulator to: control a magnitude of a processor voltage based on receiving at least one power management request signal from each of the plurality of processors; generate a processor voltage that is provided to each of the plurality of processors; and in response to a voltage change request issued by one of the plurality of processors to the single voltage regulator to increase or decrease the processor voltage, transmit an alert signal to each of the remaining plurality of processors.
