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.

Abstract: A dynamic adjustment of core power can reduce thermal margin between thermal design power (TDP) and an allowable thermal load. For example, by focusing directly on the core temperatures explicitly, a per-core closed loop temperature controller (pCLTC) can remove conservatism induced by the power level 1 policy (PL1, a policy which defines frequency and/or power for the processor under sustained load) thereby allowing for increased processor performance when there exists margin in the thermal system.

Abstract: Embodiments disclosed herein provide for monitoring performance of a processing device to manage non-precise events. A processing device includes a performance counter to track a non-precise event and to increment upon occurrence of the non-precise event, wherein the non-precise event comprises a first type of performance event that is not linked to an instruction in an instruction trace. The processing device also includes a first handler circuit to generate and store a first record, the first record comprising architectural metadata defining a state of the processing device at a time of generation of the first record, wherein the first handler circuit to generate records corresponding to precise events. The processing device further includes a second handler circuit communicably coupled to the first handler circuit, the second handler circuit to cause the first handler circuit to generate a second record for the non-precise event upon overflow of the performance counter.

Abstract: A method is provided for controlling a link. This may include determining a condition of a first device coupled to the link, receiving, at the first device, a request for a specific link state from a second device coupled to the link, and determining a power state of the link based on the determined condition of the first device.
