Abstract:
Systems and methods are disclosed for scheduling threads on a processor that has at least two different core types, such as an asymmetric multiprocessing system. Each core type can run at a plurality of selectable voltage and frequency scaling (DVFS) states. Threads from a plurality of processes can be grouped into thread groups. Execution metrics are accumulated for threads of a thread group and fed into a plurality of tunable controllers for the thread group. A closed loop performance control (CLPC) system determines a control effort for the thread group and maps the control effort to a recommended core type and DVFS state. A closed loop thermal and power management system can limit the control effort determined by the CLPC for a thread group, and limit the power, core type, and DVFS states for the system. Deferred interrupts can be used to increase performance.

Claim (Index 15):
A system comprising an asymmetric multiprocessor (AMP) having a plurality of performance cores (PCs) and a plurality of efficient cores (ECs), the AMP coupled to a memory programmed with executable instructions that, when executed by the AMP, perform operations comprising:\n determining that a thread, recommended for processing by a performance core (PC) of an asymmetric multiprocessing (AMP), is scheduled for processing by the PC; in response to determining that no PCs are available for processing the thread and that an EC is available for processing the thread:\n configuring timer of an interrupt controller to generate an interrupt after expiration of a predetermined delay value; and \n in response to determining, before the timer expires, that a PC is available to process the thread, canceling the interrupt, and processing the thread by the available PC.
