Abstract: An apparatus and method for temperature-constrained frequency control and scheduling. For example, one embodiment of a processor comprises: a plurality of cores; power management circuitry to control a frequency of each core of the plurality of cores based, at least in part, on a temperature associated with one or more cores of the plurality of cores, the power management circuitry comprising: a temperature limit-driven frequency controller to determine a first frequency limit value based on a temperature of a corresponding core reaching a first threshold; frequency prediction hardware logic to predict a temperature-constrained frequency of the corresponding core based on the first frequency limit value and an initial frequency limit value; and performance determination hardware logic to determine a new performance value for the corresponding core based on the temperature-constrained frequency, the new performance value to be provided to a task scheduler.

Abstract: Techniques for providing hardware provided guidance for efficiently scheduling workloads to an optimal compute module are described. In some examples, hardware includes a first plurality of physical processor cores of a first type to implement a plurality of logical processor cores of the first type; a second plurality of physical processor cores of a second type, wherein each core of the second type is to implement a plurality of logical processor cores of the second type; a power management unit to monitor telemetry data on the first plurality of processor cores and second plurality of processor cores and to update hardware feedback telemetry data; and thread runtime telemetry circuitry to provide a hint using the hardware feedback telemetry data to consolidate tasks on one of core types.

Abstract: Provided are systems, apparatuses, and techniques for managing processor system power and performance based on operational metrics, hardware capabilities, and/or other parameters.

Abstract: An apparatus is provided which comprises: a processing core; and circuitry to select, for a first mode of operation of the processing core, a first operating point comprising a first operating frequency and a first operating load, based at least in part on a mathematical function that substantially defines variation of a frequency and a load of the processing core for a threshold power consumption, wherein the circuitry is to select the first operating point such that a first power consumption of the processing core at the first operating point is less than or equal to the threshold power consumption.

Abstract: The time required to launch an application may be reduced by increasing the performance of the system upon receiving an input indicative of a request to launch an application and decreasing the performance of the system upon receiving a notification that the Application has successfully launched. On Android® platforms, a PowerHAL wrapper layer may be created to generate an APP_LAUNCHER_START token upon receipt of the request to launch an application and an APP_LAUNCHER_COMPLETE token when the application has successfully launched. These tokens may be passed to a Generic Kernel Interface layer that increases system performance upon receipt of the APP_LAUNCHER_START token and reduced system performance upon receipt of the APP_LAUNCHER_COMPLETE token. A safety timer may be used to return the system to a lower performance state in the event the application fails to launch.
