Hi Aditya

if you are speaking about GPC Interrupt Controller (INTC), IRQ status register

shows which peripheral waked processor, bit=1 shows that wake event happened from

particular peripheral with IRQ number listed in sect.3.2 A9 interrupts i.MX6SDL Reference Manual.

Note, GIC used for processing interrupts, simple description and example can be found in Github SDK

Best regards
