Abstract:
Described herein in various embodiments are techniques to better coordinate long wakeup events on a network processor that are due to radio or network activity with the long wakeups that are due to requests from an application processor. In one embodiment, power management logic can receive wake requests from system processes upon notice that one or more application processors are transitioning into a low power state. The power management logic can coalesce the wake requests based on a supplied margin and determine a wake timeframe in which the application processor may be opportunistically woken from the low power state. The power management logic can provide the wake timeframe for the application processor to a network processor in the system. The network processor can opportunistically cause an early wake of the application processor during the wake timeframe.
Abstract:
Systems and methods are disclosed for determining a current machine state of a processing device, predicting a future processing task to be performed by the processing device at a future time, and predicting a list of intervening processing tasks to be performed by a first time (e.g. a current time) and the start of the future processing task. The future processing task has an associated initial state. A feed-forward thermal prediction model determines a predicted future machine state at the time for starting the future processing task. Heat mitigation processes can be applied in advance of the starting of the future processing task, to meet the future initial machine state for starting the future processing task.
Abstract:
A computing system having a plurality of processing units configured to perform work by having threads assigned to the processing units. A thread scheduler is coupled to the plurality of processors and configured to schedule threads to the processing units. A power manager is coupled to the thread scheduler and controls performance states or idle states of the processing units. The thread scheduler maintains information about current performance state or idle state per processing unit. The information includes a multi-level description of the processing units in the computing system. The multi-level description includes three or more different entry values of different levels for performance state or idle state for processing units. The power manager provides the multi-level description of the processing units to the thread scheduler, which is configured to schedule threads to the processing units based on the multi-level description.
Abstract:
A method, system and program product utilize even-driven reoptimization to reallocate one or more logical partitions within a pool of logically-partitioned data processing systems in a logically-partitioned computing environment in response to detection of a system event that is likely to increase or decrease the collective resource demands of logical partitions resident in a logically-partitioned computing environment. The reoptimization may be used to consolidate logical partitions on fewer processor nodes to improve the potential for powering down hardware resources and thereby reduce power consumption.
Abstract:
Methods and apparatus relating to thermal throttling of WiDi (Wireless Display) video stream resolution are described. In an embodiment, logic generates one or more signals to cause a processor to a change the resolution and/or frame rate of a video stream in response to input from one or more sensors and one or more values. The one or more signals can also cause wireless display logic to modify a compression level of the video stream received from the processor prior to transmission of a compressed version of the video stream to a display device. Other embodiments are also disclosed and claimed.

Abstract:
A method and apparatus of a device that manages a thermal profile of a device by selectively throttling central processing unit operations of the device is described. The device manages a thermal profile of the device by adjusting a throttling a central processing unit execution of a historically high energy consuming task. In this embodiment, the device monitors thermal level of the thermal profile of the device, the device is executing a plurality of tasks that utilize a plurality of processing cores of the device. If the thermal level of the device exceeds a thermal threshold, the device identifies one of the plurality tasks as a historically high energy consuming task, and throttles this historically high energy consuming task by setting a force idle execution time for the historically high energy consuming task. The device further executes the plurality of tasks.
