Member Function Documentation

◆ addressToNodeID()

NodeID Network::addressToNodeID	(	Addr	addr,
		MachineType	mtype
	)

Map an address to the correct NodeID.

This function traverses the global address map to find the NodeID that corresponds to the given address and the type of the destination. For example for a request to a directory this function will return the NodeID of the right directory.

Parameters

the	destination address
the	type of the destination

Returns: the NodeID of the destination

◆ getPort()

Port& Network::getPort	(	const std::string &	if_name,
		PortID	idx = `InvalidPortID`
	)

inlineoverridevirtual

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_name	Port name
idx	Index in the case of a VectorPort

Returns: A reference to the given port

Reimplemented from SimObject.

Definition at line 138 of file Network.hh.

References RubyDummyPort::instance().

◆ init()

void Network::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.
