Member Function Documentation

void RubyPort::addToRetryList ( MemSlavePort port)
inlineprivate
virtual void RubyPort::descheduleDeadlockEvent ( )
pure virtual

Implemented in GPUCoalescer, RubyPortProxy, Sequencer, and DMASequencer.

Referenced by drain().

DrainState RubyPort::drain ( )
overridevirtual

Notify an object that it needs to drain its state.

If the object does not need further simulation to drain internal buffers, it returns DrainState::Drained and automatically switches to the Drained state. If the object needs more simulation, it returns DrainState::Draining and automatically enters the Draining state. Other return values are invalid.

Note
An object that has entered the Drained state can be disturbed by other objects in the system and consequently stop being drained. These perturbations are not visible in the drain state. The simulator therefore repeats the draining process until all objects return DrainState::Drained on the first call to drain().
Returns
DrainState::Drained if the object is drained at this point in time, DrainState::Draining if it needs further simulation.

Implements Drainable.

BaseMasterPort & RubyPort::getMasterPort ( const std::string &  if_name,
PortID  idx = InvalidPortID 
)
overridevirtual

Get a master port with a given name and index.

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

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

Reimplemented from MemObject.

BaseSlavePort & RubyPort::getSlavePort ( const std::string &  if_name,
PortID  idx = InvalidPortID 
)
overridevirtual

Get a slave port with a given name and index.

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

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

void RubyPort::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.
