Function Documentation

int IntcAndIpiInit

(

void

)

This function initializes Interrupt Controller and IPI drivers.

Returns

XST_SUCCESS to indicate success, otherwise XST_FAILURE.

Initialize the interrupt controller driver so that it is ready to use.

Perform a self-test to ensure that the hardware was built correctly.

Initialize IPI Driver This initialization is required to get XilSEM event notifications from PLM

Initialize CRAM scan if not initialized This is applicable when CRAM Scan is set for deferred start up.

Enable event Notifications to receive notifications from PLM upon detection of any error in CFRAME

int SetUpInterruptSystem

(

XIntc *

XIntcInstancePtr

)

This function connects the IPI interrupts to the interrupt controller and to the processor.

Parameters

Intc	instance pointer.

Returns

None.

Connect IPI interrupt handler that will be called when an interrupt for the IPI occurs, the IPI interrupt handler performs the specific interrupt processing for IPI.

Start the interrupt controller such that interrupts are enabled for all devices that cause interrupts.
