Member Function Documentation

EtherInt * DistEtherLink::getEthPort	(	const std::string &	if_name,
		int	idx
	)

overridevirtual

Additional function to return the Port of a memory object.

Implements EtherObject.

Definition at line 113 of file dist_etherlink.cc.

References EtherInt::getPeer(), localIface, and panic_if().

void DistEtherLink::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 140 of file dist_etherlink.cc.

References distIface, DistEtherLink::RxLink::doneEvent(), DPRINTF, DistIface::init(), linkDelay, and rxLink.

const Params* DistEtherLink::params ( ) const

inline

Definition at line 225 of file dist_etherlink.hh.

References SimObject::_params.

void DistEtherLink::serialize ( CheckpointOut & cp ) const

overridevirtual

Serialize an object.

Output an object's state into the current checkpoint section.

Parameters

cp	Checkpoint state

Implements Serializable.

Definition at line 124 of file dist_etherlink.cc.

References distIface, rxLink, Serializable::serializeSection(), and txLink.

void DistEtherLink::startup ( )

overridevirtual

startup() is the final initialization call before simulation.

All state is initialized (including unserialized state, if any, such as the curTick() value), so this is the appropriate place to schedule initial event(s) for objects that need them.

Reimplemented from SimObject.

Definition at line 147 of file dist_etherlink.cc.

References distIface, DPRINTF, and DistIface::startup().

void DistEtherLink::unserialize ( CheckpointIn & cp )

overridevirtual

Unserialize an object.

Read an object's state from the current checkpoint section.

Parameters
