Public Member Functions
	ReqPacketQueue (EventManager &_em, RequestPort &_mem_side_port, const std::string _label="ReqPacketQueue")
	Create a request packet queue, linked to an event manager, a memory-side port, and a label that will be used for functional print request packets.

virtual	~ReqPacketQueue ()

const std::string	name () const
	Provide a name to simplify debugging.

bool	sendTiming (PacketPtr pkt)
	Send a packet using the appropriate method for the specific subclass (request, response or snoop response).

Public Member Functions inherited from gem5::PacketQueue
size_t	size () const
	Get the size of the queue.

Tick	deferredPacketReadyTime () const
	Get the next packet ready time.

bool	checkConflict (const PacketPtr pkt, const int blk_size) const
	Check if a packet corresponding to the same address exists in the queue.

bool	trySatisfyFunctional (PacketPtr pkt)
	Check the list of buffered packets against the supplied functional request.

void	schedSendEvent (Tick when)
	Schedule a send event if we are not already waiting for a retry.

void	schedSendTiming (PacketPtr pkt, Tick when)
	Add a packet to the transmit list, and schedule a send event.

void	retry ()
	Retry sending a packet from the queue.

void	disableSanityCheck ()
	This allows a user to explicitly disable the sanity check on the size of the transmitList, which is enabled by default.

DrainState	drain () override
	Draining is the process of clearing out the states of SimObjects.These are the SimObjects that are partially executed or are partially in flight.

Public Member Functions inherited from gem5::Drainable
