Member Function Documentation

BaseSlavePort & ExternalSlave::getSlavePort ( const std::string &  if_name,
PortID  idx = InvalidPortID 
)
virtual

SlavePort interface.

Responds only to port "port"

Reimplemented from MemObject.

Definition at line 204 of file external_slave.cc.

References DPRINTF, externalPort, fatal, MemObject::getSlavePort(), portData, portHandlers, portName, and portType.

void ExternalSlave::init ( )
virtual

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 232 of file external_slave.cc.

References externalPort, fatal, BaseSlavePort::isConnected(), SimObject::name(), and SlavePort::sendRangeChange().

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

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

Port* ExternalSlave::externalPort
protected

The peer port for the gem5 port "port".

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

std::string ExternalSlave::portName
protected

Name of the bound port.

This will be name() + ".port"

std::string ExternalSlave::portType
protected

Key to select a port handler.
