In an embodiment, a processor includes a core domain with a plurality of cores and a power controller having a first logic to receive a first request to increase an operating voltage of a first core of the core domain to a second voltage, to instruct a voltage regulator to increase the operating voltage to an interim voltage, and to thereafter instruct the voltage regulator to increase the operating voltage to the second voltage. Other embodiments are described and claimed. 1a plurality of cores; anda power controller including a control logic to receive a first request to increase an operating voltage to be provided to a first core to a second voltage and, responsive to the first request, cause a voltage regulator to increase the operating voltage to an interim voltage, thereafter enable a second core to exit an inactive state and enter an active state, and thereafter enable an operating frequency of the first core to be increased.. A processor comprising: This application is a continuation of U.S. patent application Ser. No. 15/966,397, filed Apr. 30, 2018, which is a continuation of U.S. application Ser. No. 15/157,553, filed May 18, 2016, now U.S. Pat. No. 9,996,135, issued Jun. 12, 2018, which is a continuation application of U.S. Ser. No. 13/793,037, filed Mar. 11, 2013, now U.S. Pat. No. 9,367,114, issued Jun. 14, 2016, the content of which is hereby incorporated by reference.Embodiments relate to power management of a system, and more particularly to operating voltage control in a processor.Advances in semiconductor processing and logic design have permitted an increase in the amount of logic that may be present on integrated circuit devices. As a result, computer system configurations have evolved from a single or multiple integrated circuits in a system to multiple hardware threads, multiple cores, multiple devices, and/or complete systems on individual integrated circuits. Additionally, as the density of integrated circuits has grown, the power ...
