References portHandlers, and registerHandler().

Member Function Documentation

◆ getPort()

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

overridevirtual

Port interface.

Responds only to port "port"

Reimplemented from SimObject.

Definition at line 195 of file external_slave.cc.

References DPRINTF, externalPort, fatal, SimObject::getPort(), portData, portHandlers, portName, and portType.

◆ init()

void ExternalSlave::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.

Reimplemented from SimObject.

Definition at line 222 of file external_slave.cc.

References externalPort, fatal, Port::isConnected(), SimObject::name(), and ResponsePort::sendRangeChange().

◆ registerHandler()

void ExternalSlave::registerHandler	(	const std::string &	handler_name,
		Handler *	handler
	)

static

Register a handler which can provide ports with port_type == handler_name.

Definition at line 240 of file external_slave.cc.

◆ addrRanges

AddrRangeList ExternalSlave::addrRanges

protected

The Range of addresses supported by the devices on the external side of this port.

Definition at line 117 of file external_slave.hh.

Referenced by ExternalSlave::ExternalPort::getAddrRanges().

◆ externalPort

ExternalPort* ExternalSlave::externalPort

protected

The peer port for the gem5 port "port".

Referenced by getPort(), and init().

◆ portData

std::string ExternalSlave::portData

protected

Handler-specific port configuration.

Referenced by getPort().

◆ portHandlers

std::map< std::string, ExternalSlave::Handler * > ExternalSlave::portHandlers

staticprotected

Registered handlers.

Handlers are chosen using the port_type parameter on ExternalSlaves. port_types form a global namespace across the simulation and so handlers are registered into a global structure

Referenced by ExternalSlave(), getPort(), and registerHandler().

◆ portName

std::string ExternalSlave::portName

protected

Name of the bound port.

This will be name() + ".port"

Definition at line 107 of file external_slave.hh.

Referenced by getPort().

◆ portType

std::string ExternalSlave::portType

protected

Key to select a port handler.

Definition at line 110 of file external_slave.hh.
