This function must be called by OALIntrDoneIrqs if your implementation uses hardware platform callbacks. This function must be called for each IRQ in the list before the IRQ is re-enabled.

Syntax

UINT32 BSPIntrDoneIrq(
  UINT32 irq
);

Parameters

  • irq
    [in] The IRQ to be re-enabled.

Return Value

Returns the IRQ that must be scanned on the primary interrupt controller to signal the end of interrupt processing. Returns IRQ_UNDEFINED if no other IRQ needs to be scanned.

Remarks

BSPIntrDoneIrq can also perform board-specific actions and modify an IRQ.

The system cannot be pre-empted when this function is called.

BSPIntrDoneIrq should re-enable the interrupt if the interrupt was previously masked.
