Abstract: A method is described. The method includes polling a queue a plurality of times over a plurality of intervals, where, the queue feeds work items to a processor. The method includes determining, from the polling, respective work item flow metrics for the plurality of intervals. The method includes determining a processor's performance setting based on the plurality of respective work item flow metrics.

Abstract: Examples described herein relate to circuitry to cause a processor to enter reduced power consumption state and circuitry to, based on a write to one or more of multiple memory regions, cause the processor to exit reduced power consumption state, wherein the multiple memory regions store receive descriptors associated with one or more packets received by a network interface device. In some examples, multiple memory regions are defined by a driver of the network interface device. In some examples, the reduced power consumption state comprises a TPAUSE state.

Abstract: Examples herein relate to assigning, by a system agent of a central processing unit (CPU), an operating frequency to a core group based priority level of the core group while avoiding throttling of the system agent. Avoiding throttling of the system agent can include maintaining a minimum performance level of the system agent. A minimum performance level of the system agent can be based on a minimum operating frequency. Assigning, by a system agent of a central processing unit, an operating frequency to a core group based priority level of the core group while avoiding throttling of the system agent can avoid a thermal limit of the CPU. Avoiding thermal limit of the CPU can include adjusting the operating frequency to the core group to avoid performance indicators of the CPU. A performance indicator can indicate CPU utilization corresponds to Thermal Design Point (TDP).
