◆ completeRequest()

◆ generatePkt()

void gem5::GarnetSyntheticTraffic::generatePkt ( )
protected

◆ getPort()

Port & gem5::GarnetSyntheticTraffic::getPort ( const std::string &  if_name,
PortID  idx = InvalidPortID 
)
overridevirtual

Get a port with a given name and index.

This is used at binding time and returns a reference to a protocol-agnostic port.

gem5 has a request and response port interface. All memory objects are connected together via ports. These ports provide a rigid interface between these memory objects. These ports implement three different memory system modes: timing, atomic, and functional. The most important mode is the timing mode and here timing mode is used for conducting cycle-level timing experiments. The other modes are only used in special circumstances and should not be used to conduct cycle-level timing experiments. The other modes are only used in special circumstances. These ports allow SimObjects to communicate with each other.

Parameters
if_namePort name
idxIndex in the case of a VectorPort
Returns
A reference to the given port

◆ init()

void gem5::GarnetSyntheticTraffic::init ( )
overridevirtual

init() is called after all C++ SimObjects have been created and all ports are connected.

Initializations that are independent of unserialization but rely on a fully instantiated and connected SimObject graph should be done here.
