Member Function Documentation

◆ addToRetryList()

void RubyPort::addToRetryList ( MemSlavePort port)
inlineprivate

◆ descheduleDeadlockEvent()

virtual void RubyPort::descheduleDeadlockEvent ( )
pure virtual

Implemented in GPUCoalescer, Sequencer, RubyPortProxy, and DMASequencer.

Referenced by drain(), and ~RubyPort().

◆ 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.
