◆ RegisterIntrHandler()
| int RegisterIntrHandler | ( | int | irq, |
| int | mode, | ||
| int(*)(void *) | 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.

References CpuResumeIntr(), CpuSuspendIntr(), IOP_IRQ_SW1, IOP_IRQ_SW2, and QueryIntrContext().
◆ 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.

Referenced by shutdown().
◆ 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 346 of file intrman.c.
References CpuResumeIntr(), and CpuSuspendIntr().
◆ 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.

Referenced by shutdown().
◆ 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.
◆ 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.

◆ 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.

◆ 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.

◆ 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 494 of file intrman.c.
References CpuResumeIntr(), CpuSuspendIntr(), and IOP_IRQ_DMA_BERR.
◆ 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 468 of file intrman.c.
References CpuResumeIntr(), CpuSuspendIntr(), and IOP_IRQ_DMA_BERR.
◆ 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.
