The PSM generates a core interrupt and a dedicated inter-processor interrupt (IPI).
- PSM core system interrupt
- PSM dedicated inter-processor interrupt (IPI)
The PSM also receives all the system interrupts via its GIC proxy registers.
Core Interrupts
The PPU generates a system interrupt when the APB programming interface detects an address decode error.
System Interrupts
The PSM can be a GIC proxy client for the system interrupts. The interrupt masking is controlled by the PSM global registers.
