3.9 Power Aware Interrupt Routing (PAIR)

The processor added enhanced power-performance technology which routes interrupts

to threads or cores based on their sleep states. For example concerning energy

savings, it routes the interrupt to the active cores without waking the deep idle cores.

For Performance, it routes the interrupt to the idle (C1) cores without interrupting the

already heavily loaded cores. This enhancement is mostly beneficial for high interrupt

scenarios like Gigabit LAN, WLAN peripherals, and so on.
