Abstract

Computing system voltage control methods include receiving an indication of a first performance state. The first performance state is associated with a first voltage and applies to at least one computing system component. The indication of the first performance state is received by a first computing system component from a second computing system component. An indication of a second performance state is received, wherein the second performance state is associated with a second voltage that is not equal to the first voltage. It is determined whether the second performance state is within a range defined by a minimum performance state and a maximum performance state. Responsive to determining that the second performance state is within the range defined by the minimum performance state and the 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.
