Abstract

An indication of a first performance state is received, the first performance state being associated with a first voltage. The first performance state applies to at least one computing system component and the indication is received by a computing system component distinct from the requesting computing system component. An indication of a second performance state is received. The second performance state is associated with a second voltage that is different from the first voltage. It is determined whether the second performance state is within a range defined by a minimum and maximum performance state. Responsive to a determination that the second performance state is within the minimum and maximum performance state, the voltage of the at least one computing system component is set equal to the voltage associated with the second performance state.
