Introduction

This file contains ISR function declaration for CDD IPC Driver.

CDD Driver ISR category level
' This file provides ISR API's that is used to receive and process events from remote cores For each remote core an associated ISR is required In cases where multiple cores interrupts are mapped to one interrupt an single ISR would suffice Version 01.00.00 See also MCAL_IPC_ISR Defines for CDD Driver ISR ISR category level

	A Mailbox can raise multiple interrupts. In this implementation, the Mailbox new message interrupt is used determine presence of data from the remote core in the vring.

void Cdd_IpcIrq_Fun ( uint32 srcProcId )

A Mailbox can raise multiple interrupts. In this implementation, the Mailbox new message interrupt is used determine presence of data from the remote core in the vring.

Typically, we would have 1 interrupt for each remote core. Due to system resource needs, multiple remote cores could use a single interrupt.

Depending on the SoC variant, the isr to registered with interrupt will change. Please refer CDD IPC example application to associate right ISR with interrupt.
