Dispatching interrupts in a multi-processor system based on power and performance factors

A system for handling interrupts, comprising:

• a plurality of processors;
• an interrupt controller;
• and
• a plurality of interrupt-generating devices, wherein the interrupt controller is operative to:
• receive a power and performance status of each processor, the power and performance status indicated by a plurality of factors that affect power consumption and processor performance;
• receive a request for an interrupt from one of the interrupt-generating devices, the interrupt being generated in a usage scenario of the system;
• calculate a weighted combination of the factors for each processor, wherein each factor is weighted based on the usage scenario;
• identify one of the processors for handling the interrupt based on the weighted combination calculated for each processor;
• and
• dispatch the interrupt to the identified one of the processors.
