The A72 CPU recieves interrupts at its inputs (IRQ, FIQ, VIRQ, VFIQ) via the dedicated Arm GIC-500 Interrupt Controller which is integrated inside the Compute Cluster and is tightly-coupled to the A72. The GIC-500 supports both A72 cores in the system. The GIC-500 is compliant to the Arm GICv3 specification and supports four types of interrupts:
The mapping of PPIs and SPIs to the GIC-500 interrupt inputs can be found in TBD.
For a brief list of features supported by the GIC-500 module, see Generic Interrupt Controller (GIC). For detailed description of the GIC-500 module, see the Arm® CoreLink™ GIC-500 Generic Interrupt Controller Technical Reference Manual.
