摘要： A method and system for energy management in a simultaneous multi-threaded (SMT) processing system including per-thread device usage monitoring provides control of energy usage that accommodates thread parallelism. Per-device usage information is measured and stored on a per-thread basis, so that upon a context switch, the previous usage evaluation state can be restored. The per-thread usage information is used to adjust the thresholds of device energy management decision control logic, so that energy use can be managed with consideration as to which threads will be running in a given execution slice. A device controller can then provide for per-thread control of attached device power management states without intervention by the processor and without losing the historical evaluation state when a process is switched out. The device controller may be a memory controller and the controlled devices memory modules or banks within modules if individual banks can be power-managed. Local thresholds provide the decision-making mechanism for each controlled device and are adjusted by the operating system in conformity with the measured usage level for threads executing within the processing system. The per-thread usage information may be obtained from a performance monitoring unit that is located within or external to the device controller and the usage monitoring state is then retrieved and replaced by the operating system at each context switch.

摘要： A method and system for power management including local bounding of device group power consumption provides the responsiveness of local power control while meeting global system power consumption and power dissipation limits. At the system level, a global power bound is determined and divided among groups of devices in the system so that local bounds are determined that meet the global system bound. The local bounds are communicated to device controllers associated with each group of devices and the device controllers control the power management states of the associated devices in the group to meet the local bound. Thus, by action of all of the device controllers, the global bound is met. The controllers may be memory controllers and the devices memory modules, or the devices may be other devices within a processing system having associated local controllers. Alternatively or in concert, the devices may be entire processing systems and the associated controller a power management controller for associated processing systems, whereby multiple processing locales may be power-managed consistent with a global power consumption budget.

摘要： A method for adapting the periodicity of polling for pending service requests, by polling system devices for pending service requests, recording whether or not there was a pending service request and, based on accumulated data, determining whether or not the system devices are idle. Based on this determination, the system may elect to enter a power conservation mode until device activity is signaled, or an adjustable period of time elapses. The adaptation mechanism may alter the periodicity of the timer interrupt, disable or enable device interrupts, and modify variables used to determine system idleness (including minimum latency and minimum idleness thresholds). In this manner, the system can conserve power while maintaining system performance and responsiveness.
