Abstract: Various embodiments of methods and systems context-aware thermal management in a portable computing device (“PCD”) are disclosed. Notably, the environmental context to which a PCD is subjected may have significant impact on the PCD's thermal energy dissipation efficiency. Embodiments of the solution seek to leverage knowledge of a PCD's environmental context to modify or adjust thermal policy parameters applied within a PCD in response to a thermal event within the PCD.

Abstract: Disclosed are methods and systems for proactive power and performance management of workloads in a portable computing device (“PCD”), such as, but not limited to, a virtual reality (“VR”) or augmented reality (“AR”) workload. An exemplary embodiment determines that a target application (or an application queued for execution) is compatible with a proactive throttling policy. Advantageously, for those applications that are compatible with a proactive throttling policy, embodiments of the solution may rely on historical performance data of those applications to preset performance parameters such that the PCD may deliver a consistent user experience over time uninterrupted by fluctuations in processing performance resulting from reactive thermal throttling policies.

Abstract: Various embodiments of methods and systems for intelligent thermal power management implemented in a portable computing device (“PCD”) are disclosed. To mitigate or alleviate unwanted workload migration that could exacerbate a thermal energy generation event in a processing component having heterogeneous processing core clusters, embodiments of the solution apply mitigation measures in a predetermined order to the large cluster before applying any thermal mitigation measures to the small cluster.
