This guide has introduced the Arm CoreLink GICv3 and v4 architecture and how to initialize a GIC in a bare metal environment. This guide briefly introduced the Locality-specific Peripheral Interrupts (LPI) interrupt type. How LPIs are handled and initialized is covered in our guide Arm CoreLink Generic Interrupt Controller v3 and v4: Locality-specific Peripheral Interrupts.

The Arm CoreLink GIC architecture supports virtualization. To learn more about virtualization features in GICv3 and GICv4, read our guide Arm CoreLink Generic Interrupt Controller v3 and v4: Virtualization.
