The GIC supports:

The GIC includes interrupt grouping functionality that supports:

The Cortex-A57 MPCore processor implements the GIC CPU interface as described in the Generic Interrupt Controller (GICv3) architecture. It can interface with a GICv3 Distributor component in the system.

This chapter only describes features that are specific to the Cortex-A57 MPCore multiprocessor implementation.
