sceKernelResumeIntrForDriver

Version NID
0.990-3.60 0xA4C772AF

Controller

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

Registered Interrupts

As specified in the GIC Architecture Specification, interrupt IDs 0 to 15 are reserved for Software Generated Interrupts (SGIs), while interrupt IDs 16 to 31 are reserved for Private Peripheral Interrupts (PPIs). There are no private peripherals on the PS Vita so PPIs are unused.

It appears the PS Vita's GIC implements priority bits [7:1] i.e. it only supports 128 priority levels. This means all values in the Priority column should be divided by 2.

The Target CPU indicates the CPU(s) the exception can be signaled to - "All" means it can be signaled to any CPU and 0x-prefixed values are masks.

Secure Interrupts

Those interrupts are marked as Secure using the GIC's ICDISR by SKBL. It also marks interrupts 96-111 as Secure; however, those IDs have never been seen in use. All other interrupts are marked as Non-Secure.
