sceKernelReleaseIntrHandlerForDriver

Version NID
0.990-3.60 0xD6009B98

This function first performs a disable and then removes the current interrupt handler associated with the interrupt intr_code. 

int sceKernelReleaseIntrHandlerForDriver(int intr_code);

sceKernelDisableIntrForDriver

Version NID
0.990-3.60 0x180435EC 
int sceKernelDisableIntrForDriver(int intr_code);

This function writes 1 << (intr_code % 32) to the Interrupt Disable Registers (offset 0x180 from the Interrupt Distributor registers) at 0x180 + (intr_code / 32) * 4.

sceKernelEnableIntrForDriver

Version NID
0.990-3.60 0x7117E827 
int sceKernelEnableIntrForDriver(int intr_code);

This function writes 1 << (intr_code % 32) to the Interrupt Enable Registers (offset 0x100 from the Interrupt Distributor registers) at 0x100 + (intr_code / 32) * 4.

sceKernelResumeIntrForDriver

Version NID
0.990-3.60 0xA4C772AF 
int sceKernelResumeIntrForDriver(int intr_code, int enabled);

Enables or disables an interrupt. If a 0 is passed to enabled, it acts as sceKernelDisableIntrForDriver, and if a 1 is passed, it acts as sceKernelEnableIntrForDriver.

sceKernelSuspendIntrForDriver

Version NID
0.990-3.60 0x6EC07C56 
int sceKernelSuspendIntrForDriver(int intr_code, int *enabled);

This function returns whether the interrupt intr_code is enabled or not. If it's enabled, a 1 will be written to enabled and a 0 otherwise. To check the enable status, the function checks the bit number intr_code % 32 of the Interrupt Enable register (offset 0x100 from the Interrupt Distributor registers) at 0x100 + (intr_code / 32) * 4.

Version NID
0.990-3.60 0xA269003D 
int sceKernelGetIntrPendingStatusForDebuggerForDriver(int intr_code);

This function returns whether the interrupt intr_code is pending or not. If it's pending, a 1 will be returned, and a 0 will be returned otherwise. To check the pending status, the function checks the bit number intr_code % 32 of the Interrupt Set-Pending Registers (offset 0x200 from the Interrupt Distributor registers) at 0x200 + (intr_code / 32) * 4.

sceKernelClearIntrPendingStatusForDebuggerForDriver

Version NID
0.990-3.60 0x4DC48A01 
int sceKernelClearIntrPendingStatusForDebuggerForDriver(int intr_code);

sceKernelSetIntrTargetCpuForDriver

Version NID
0.990-3.60 0x973BACCC 
int sceKernelSetIntrTargetCpuForDriver(int intr_code, int cpu_mask);

This function writes the bits 0-8 or 16-24 of cpu_mask, depending on whether the mask is in former or the latter bits, to the Interrupt Processor Targets Registers (offset 0x800 from the Interrupt Distributor registers) at 0x800 + intr_code

sceKernelGetIntrTargetCpuForDriver

Version NID
0.990-3.60 0x353CFAAE

0.990-3.60 0x29F62500 
int sceKernelGenerateSoftIntrForDriver(int intr_code, unsigned int target_list_filter, unsigned int cpu_target_list);

This function triggers a SGI (software generated interrupt) by writing (target_list_filter << 24) | (cpu_target_list << 16) | intr_code to the Software Generated Interrupt Register (offset 0xF00 from the Interrupt Distributor registers, physical address 0x1A001F00). Note: intr_code must be between 0x0 and 0xF.

sceKernelIsIntrContextForDriver

Version NID
0.931-3.60 0x182EE3E3

Indicates whether or not the thread is currently handling an interrupt.

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.
