Abstract: An apparatus and method for intelligently scheduling threads across a plurality of logical processors. For example, one embodiment of a processor comprises: a plurality of cores to be allocated to form a first plurality of logical processors (LPs) to execute threads, wherein one or more logical processors (LPs) are to be associated with each core of the plurality of cores; scheduling guide circuitry to: monitor execution characteristics of the first plurality of LPs and the threads; generate a first plurality of LP rankings, each LP ranking including all or a subset of the plurality of LPs in a particular order; and store the first plurality of LP rankings in a memory to be provided to a scheduler, the scheduler to schedule the threads on the plurality of LPs using the first plurality of LP rankings; a power controller to execute power management code to perform power management operations including independently adjusting frequencies and/or voltages of one or more of the plurality of cores; wherein in response to a core configuration command to deactivate a first core of the plurality of cores, the power controller or privileged program code executed on the processor are to update the memory with an indication of deactivation of the first core, wherein responsive to the indication of deactivation of the first core, the scheduler is to modify the scheduling of the threads.

Abstract: Hierarchical Power Management (HPM) architecture considers the limits of scaling on a power management controller, the autonomy at each die, and provides a unified view of the package to a platform. At a simplest level, HPM architecture has a supervisor and one or more supervisee power management units (PMUs) that communicate via at least two different communication fabrics. Each PMU can behave as a supervisor for a number of supervisee PMUs in a particular domain. HPM addresses these needs for products that comprise a collection of dice with varying levels of power and thermal management capabilities and needs. HPM serves as a unified mechanism than can span collection of dice of varying capability and function, which together form a traditional system-on-chip (SoC). HPM provides a basis for managing power and thermals across a diverse set of dice.

Abstract: An apparatus and method for intelligently scheduling threads across a plurality of logical processors. For example, one embodiment of a processor comprises: a plurality of cores; one or more peripheral component interconnects to couple the plurality of cores to memory, and in response to a core configuration command to deactivate a core of the plurality of cores, a region within the memory is updated with an indication of deactivation of the core.

Abstract: Examples described herein relate to circuitry to: monitor utilization data for a plurality of processes; determine one or more priority levels associated with at least one of the plurality of processes based on policy parameters; and adjust a frequency of operation of the interface circuitry based on the monitored utilization data and the determined priority levels of the processes. In some examples, adjust the frequency of operation of the interface circuitry is to prioritize frequency of operation requested by a higher priority workload over a frequency of operations requested by a lower priority workload.

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.
