Abstract: Examples described herein relate to at least one multi-core processor and a circuitry can determine and output energy usage of a process regardless of a core of the at least one multi-core processor that executes the process. The circuitry can determine the energy usage of the process based on cache operations and processor microoperations associated with the process. The energy usage of the process can be based on dynamic capacitance (Cdyn) levels and one or more of: temperature of the at least one multi-core processor, input voltage temperature to the at least one multi-core processor, and/or frequency of the at least one multi-core processor.

Abstract: A processing device includes a plurality of processing cores, a control register, associated with a first processing core of the plurality of processing cores, to store a first base clock frequency value at which the first processing core is to run, and a power management circuit to receive a base clock frequency request comprising a second base clock frequency value, store the second base clock frequency value in the control register to cause the first processing core to run at the second base clock frequency value, and expose the second base clock frequency value on a hardware interface associated with the power management circuit.
