◆ iop_irq_list

enum iop_irq_list

Enumerator
IOP_IRQ_DMA	Original DMA controller interrupt (DMA channels 0-6)
IOP_IRQ_DVD	Not sure what this is, if INUM_CDROM is the interrupt CDVDMAN uses.
IOP_IRQ_EXTR	Expansion interface on the mainboard. Unused (and unpopulated) on most retail mainboards, but used by DECI2 in the TOOL unit as the MRP interface. In PS mode, INUM_PIO seems to be triggered instead.
IOP_IRQ_FDMA	Firewire DMA
IOP_IRQ_DMA_BERR	DMA bus error
IOP_IRQ_SW1	R3000A Software Interrupt 1 (Used by DECI2).
IOP_IRQ_SW2	R3000A Software Interrupt 2 (Used by DRVTIF of DECI2)

Function Documentation

◆ RegisterIntrHandler()

int RegisterIntrHandler	(	int	irq,
		int	mode,
		int()(void arg)	handler,
		void *	arg
	)

Register an interrupt handler for the specified interrupt.

Parameters

irq	Interrupt cause to register an interrupt handler for.
mode	Specifies the registers that will be preserved before the interrupt handler is run. The more registers are preserved, the slower the operation. Mode 0: $at, $v0, $v1, $a0, $a1, $a2, $a3 and $ra can be used. Mode 1: All mode 0 registers, as well as $t0-$t9, $gp and $fp can be used. Mode 2: All mode 1 registers, as well as $s0-$s7 can be used.
handler	A pointer to the interrupt handler that will be associated with the interrupt.
arg	An optional pointer to data that will be passed to the interrupt handler, whenever it is to be invoked.

Returns: 0 on success, non-zero error code on failure.

Definition at line 115 of file intrman.c.

◆ ReleaseIntrHandler()

int ReleaseIntrHandler ( int irq )

Releases (deregisters) the interrupt handler for the specified interrupt.

Parameters

irq	Interrupt cause to release the interrupt handler for.

Returns: 0 on success, non-zero error code on failure.

Definition at line 157 of file intrman.c.

◆ EnableIntr()

int EnableIntr ( int irq )

Enables (unmasks) the specified hardware interrupt cause.

Parameters

irq	Interrupt cause to enable.

Returns: Returns 0 on success, non-zero error code on failure.

Definition at line 336 of file intrman.c.

◆ DisableIntr()

int DisableIntr	(	int	irq,
		int *	res
	)

Disables (masks) the specified hardware interrupt cause.

Parameters

irq	Interrupt cause to disable.
res	Pointer to a variable to receive the interrupt number of the interrupt that was disabled.

Returns: Returns 0 on success, non-zero error code on failure.

Definition at line 385 of file intrman.c.

◆ CpuDisableIntr()

int CpuDisableIntr ( )

Disables interrupts, regardless of the current statue. This is deprecated. The interrupt mask registers for each interrupt cause will not be changed. May be called from an interrupt or thread context.

Returns: Returns 0 on success, non-zero error code on failure.

Definition at line 228 of file intrman.c.

◆ CpuEnableIntr()

int CpuEnableIntr ( )

Enables interrupts, regardless of the current state. This is deprecated. The interrupt mask registers for each interrupt cause will not be changed. May be called from an interrupt or thread context.

Returns: Returns 0 on success, non-zero error code on failure.

Definition at line 240 of file intrman.c.

◆ CpuSuspendIntr()

int CpuSuspendIntr ( int * state )

Disables interrupts. The interrupt mask registers for each interrupt cause will not be changed. May be called from an interrupt or thread context.

Parameters

state A pointer to a variable that will store the current interrupt status. Even if KE_CPUDI is returned, state will be set appropriately.

Returns: Returns 0 on success, non-zero error code on failure.

See also: CpuResumeIntr()

Definition at line 195 of file intrman.c.

Referenced by EnterCritical(), and sceCdPOffCallback().

◆ CpuResumeIntr()

int CpuResumeIntr ( int state )

Enables interrupts. The interrupt mask registers for each interrupt cause will not be changed. May be called from an interrupt or thread context.

Parameters

state The previous state of interrupts, as indicated by the preceeding call to CpuSuspendIntr().

Returns: Returns 0 on success, non-zero error code on failure.

See also: CpuSuspendIntr()

Definition at line 217 of file intrman.c.

Referenced by ExitCritical(), and sceCdPOffCallback().

◆ CpuInvokeInKmode()

int CpuInvokeInKmode	(	void *	function,
			...
	)

Invokes a function in kernel mode via a syscall handler. This is usually used for synchronization between interrupt and DECI2 contexts.

Parameters

function A pointer to the function to call. Specify other arguments for the function, after function.

Returns: The return value of the function.

◆ DisableDispatchIntr()

void DisableDispatchIntr ( int irq )

Disables dispatching of the interrupt handler, by INTRMAN. Used by DECI2, when DECI2RS is to manage the SIF2 and SBUS interrupts. This does not change the interrupt mask status.

Parameters

irq	The interrupt to mask in software.

Definition at line 484 of file intrman.c.

◆ EnableDispatchIntr()

void EnableDispatchIntr ( int irq )

Enables dispatching of the interrupt handler, by INTRMAN. This does not change the interrupt mask status.

Parameters

irq	The interrupt to unmask in software.

Definition at line 458 of file intrman.c.

◆ QueryIntrContext()

int QueryIntrContext ( void )

Indicates whether execution is currently within an interrupt or thread context.

Returns: 1 if within the interrupt context, 0 if not.

◆ QueryIntrStack()

int QueryIntrStack ( void * sp )

Indicates whether the specified stack pointer is within the interrupt stack.

Parameters

sp	The stack pointer to check.

Returns: 1 if the specified stack pointer is within the interrupt stack, 0 if not.

◆ SetNewCtxCb()

void SetNewCtxCb ( void * cb )

These set callback functions for thread support Only the thread manager should set these
