1. A method for changing performance states of a processor, comprising: receiving a desired end performance state for a processor, wherein the desired end performance state is associated with an end state minimum voltage; determining an intermediate performance state for the processor, wherein the intermediate performance state includes a performance state for the processor that is between a current performance state of the processor and the desired end performance state, and wherein the intermediate performance state is associated with an intermediate state minimum voltage; initiating a voltage increase of a provided voltage to the processor to provide the end state minimum voltage; and determining that the provided voltage includes the intermediate state minimum voltage and, in response, changing the performance state of the processor to the intermediate performance state that is associated with the intermediate state minimum voltage.
