The following table shows the Interrupt functions.
| Programming Element | Description |
|---|---|
| BSPIntrActiveIrq | This function translates IRQs for chaining the controller interrupt. It is called from the interrupt handler if your implementation uses hardware platform callbacks. |
| BSPIntrDisableIrq | This function must be called by OALIntrDisableIrqs if your implementation uses hardware platform callbacks. |
| BSPIntrDoneIrq | This function must be called by OALIntrDoneIrqs if your implementation uses hardware platform callbacks. |
| BSPIntrEnableIrq | This function must be called by OALIntrEnableIrqs if your implementation uses hardware platform callbacks. |
| BSPIntrInit | This function allows the BSP to initialize a secondary interrupt controller. |
| BSPIntrRequestIrqs | This function is called by OALIntrRequestIrqs if your implementation uses hardware platform callbacks and the device is not recognized. |
| OALIntrDisableIrqs | This function disables the list of interrupts identified by an IRQ. |
| OALIntrDoneIrqs | This function scans the list of interrupts identified by an IRQ, signaling the end of interrupt processing. |
| OALIntrEnableIrqs | This function enables the list of interrupts identified by an IRQ. |
| OALIntrInit | This function initializes the interrupt hardware. It is usually called during the system initialization process. |
| OALIntrMapInit | This function initializes the mapping structure that describes bi-directional mapping between IRQs and SYSINTR logical interrupts. |
| OALIntrReleaseSysIntr | This function releases a SYSINTR. |
| OALIntrRequestIrqs | This function returns the list of IRQs for the device. |
| OALIntrRequestSysIntr | This function allocates a new SYSINTR value for a specified IRQ list. |
| OALIntrStaticTranslate | This function sets the static mapping between an IRQ and a SYSINTR. OALIntrStaticTranslate is typically used during system initialization for legacy drivers. |
| OALIntrTranslateIrq | This function returns the SYSINTR for a specified IRQ based on the static mapping. |
| OALIntrTranslateSysIntr | This function returns the list of IRQs for a specified SYSINTR. |
| OALIoCtlHalReleaseSysIntr | OALIoCtlHalReleaseSysIntr releases a previously-requested SYSINTR. |
| OALIoCtlHalRequestIrq | OALIoCtlHalRequestIrq returns the IRQ for a device on a specified location. |
| OALIoCtlHalRequestSysIntr | OALIoCtlHalRequestSysIntr returns an existing SYSINTR for non-shareable IRQs and creates a new IRQ-to-SYSINTR mapping for shareable IRQs. |
