Enhanced power management for support of priority system events

A non-transitory computer-readable storage medium having stored thereon data representing sequences of instructions that, when executed by a processor, cause the processor to perform operations comprising:

• storing information in a registry regarding one or more events for a system that are designated as priority events;
• maintaining a first energy budget and a second residual energy budget for the system;
• detecting a system event;
• and
• determining whether to authorize execution of a detected system event in a first power mode based on a residual energy budget for the first power mode and determining that the detected system event is designated as a priority event.

A mobile device comprising:

• a system on chip (SoC), the SoC including:
• a processing element;
• a memory including a registry for information regarding one or more SoC events that are designated as priority events;
• a mechanism to track operation of events that require execution in a first power mode;
• and
• a power control unit, including circuitry, operable to authorize execution of a detected system event in the first power mode based on a residual energy budget for the first power mode and determining that the detected system event is designated as a priority event.
