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.
