Abstract: Systems, apparatuses and methods may provide for technology that automatically determines a runtime performance of a plurality of heterogeneous processing units based on system-level thread characteristics, wherein the runtime performance is determined on a per performance class basis. The technology may also automatically determine a runtime energy efficiency of the heterogeneous processing units, wherein the runtime energy efficiency is determined on a per efficiency class basis. In one example, technology selectively unparks one or more of the heterogeneous processing units based on the runtime performance and the runtime energy efficiency.

Abstract: A processor core energy-efficiency core ranking scheme akin to a favored core in a multi-core processor system. The favored core is the energy-efficient core that allows an SoC to use the core with the lowest Vmin for energy-efficiency. Such Vmin values may be fused in appropriate registers or stored in NVM during HVM. An OS scheduler achieves optimal energy performance using the core ranking information to schedule certain applications on the core with lowest Vmin. A bootstrap flow identifies a bootstrap processor core (BSP) as the most energy efficiency core of the SoC and assigns that core the lowest APIC ID value according to the lowest Vmin. Upon reading the fuses or NVM, the microcode/BIOS calculates and ranks the cores. As such, microcode/BIOS calculates and ranks core APIC IDs based on efficiency around LFM frequencies. Based on the calculated and ranked cores, the microcode or BIOS transfers BSP ownership to the most efficiency core.

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 logical processors including comprising one or more of a first logical processor type and a second logical processor type, the first logical processor type associated with a first core type and the second logical processor type associated with a second core type; a scheduler to schedule a plurality of threads for execution on the plurality of logical processors in accordance with performance data associated with the plurality of threads; wherein if the performance data indicates that a new thread should be executed on a logical processor of the first logical processor type, but all logical processors of the first logical processor type are busy, the scheduler to determine whether to migrate a second thread from the logical processors of the first logical processor type to a logical processor of the second logical processor type based on an evaluation of first and second performance values associated with execution of the first thread on the first or second logical processor types, respectively, and further based on an evaluation of third and fourth performance values associated with execution of the second thread on the first or second logical processor types, respectively.
