    摘要: Technologies for collaborative hardware-software power management include a computing device having a processor that supports a low-power idle state. The low-power idle state may be connected standby or a low-power audio playback state. The computing device detects a present usage scenario and determines whether the usage scenario qualifies for a power boost. Qualifying usage scenarios may include low-power audio playback, screen-on interactive use, and I/O-bound workloads. For qualifying usage scenarios, the computing device applies a boosted power management policy that increases power consumption and performance compared to a default power management policy. The default power management policy may base performance and power consumption on recent processor utilization. The computing device may generate one or more hardware hints to increase performance and power consumption, such as increasing the processor p-state or setting the value of an energy performance bias register. Other embodiments are described and claimed.

    摘要: An apparatus, method and system is described herein for efficiently balancing performance and power between processing elements based on measured workloads. If a workload of a processing element indicates that it is a bottleneck, then its performance may be increased. However, if a platform or integrated circuit including the processing element is already operating at a power or thermal limit, the increase in performance is counterbalanced by a reduction or cap in another processing elements performance to maintain compliance with the power or thermal limit. As a result, bottlenecks are identified and alleviated by balancing power allocation, even when multiple processing elements are operating at a power or thermal limit.
