SceKernelIntrMgr is a kernel module that is primary responsible for setting up external and internal interrupts. Notably, it facilitates communication with the F00D Processor.

Module

This module exists in both non-secure and secure world. The non-secure world SELF can be found in os0:kd/intrmgr.skprx. It also can be found in the Boot Image.

Controller

The interrupt controller is defined in the MPCore TRM [1]. The PERIPHBASE address (physical) is 0x1A000000.

Registered Interrupts

As specified in GIC Architecture, interrupt 0-15 are software generated interrupts. There are also no private peripheral interrupts (16-31) implemented. Core Handler indicates which core handles the exception. "All" means it can be handled by any core.
