Interrupt Functions (Compact 2013)

10/16/2014

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.
