void	bind (Port &peer) override
	Bind this request port to response port. More...

void	unbind () override
	Unbind port. More...

void	recvTokens (int num_tokens)

	Attempt to send a timing snoop response packet to the response port by calling its corresponding receive function. More...

virtual void	sendRetryResp ()
	Send a retry to the response port that previously attempted a sendTimingResp to this request port and failed. More...

Public Member Functions inherited from gem5::Port
virtual	~Port ()
	Virtual destructor due to inheritance. More...

Port &	getPeer ()
