Detailed Description

Driver for ARM Generic Interrupt Controller V3 Interrupt Translation Service.

The Generic Interrupt Controller (GIC) Interrupt Translation Service translates an input EventID from a device, identified by its DeviceID, determines a corresponding INTID for this input and the target Redistributor and, through this, the target PE for that INTID.
