A computing device includes a cooling device and a cooling activity monitor configured to assess a cooling activity of the cooling device. A cooling activity reporter is configured to, based at least in part on the cooling activity of the cooling device crossing a predefined cooling activity threshold, communicate a cooling activity indication to a resource manager of the computing device.

Systems and methods for managing a power budget are provided. The method includes designating, by a power budget manager implemented on at least one processor, each of one or more applications with an individual quality of service (QoS) designation, the one or more applications executable by the at least one processor, assigning, by the power budget manager, a throttling priority to each of the one or more applications based on the individual QoS designations, determining, by the power budget manager, whether a platform mitigation threshold is exceeded, and responsive to determining that the platform mitigation threshold is exceeded, throttling, by the power budget manager, processing power allocated to at least one application of the one or more applications based on the throttling prioritization.

Power budget management using quality of service (QoS)

Each processor core in a computing device supports various different frequency ranges, also referred to as p-states, and can operate to run threads at any one of those different frequency ranges. Threads in the computing device are assigned one of multiple importance levels. A processor core is configured to run at a particular frequency range or in accordance with a particular energy performance preference based on the importance level of the thread it is running. A utilization factor of a processor core can also be determined over some time duration, the utilization factor being based on the amount of time during the time duration that the processor core was running a thread(s), and also based on the importance levels of the thread(s) run during the time duration. The utilization factor can then be used to determine whether to park the processor core.
