title: Marvell ICU Interrupt Controller
description:
The Marvell ICU (Interrupt Consolidation Unit) controller is responsible for
collecting all wired-interrupt sources in the CP and communicating them to the
GIC in the AP. The unit translates interrupt requests on input wires to MSG
memory mapped transactions to the GIC. These messages access different GIC
memory areas depending on their type (NSR, SR, SEI, REI, etc).
