Receive a timing snoop request from the peer.

◆ sendReq()

bool gem5::TimingRequestProtocol::sendReq	(	TimingResponseProtocol *	peer,
		PacketPtr	pkt
	)

protected

Attempt to send a timing request to the peer by calling its corresponding receive function.

If the send does not succeed, as indicated by the return value, then the sender must wait for a recvReqRetry at which point it can re-issue a sendTimingReq.

Parameters

peer	Peer to send packet to.
pkt	Packet to send.

Returns: If the send was succesful or not.

◆ sendRetryResp()

void gem5::TimingRequestProtocol::sendRetryResp ( TimingResponseProtocol * peer )

protected

Send a retry to the peer that previously attempted a sendTimingResp to this protocol and failed.

Definition at line 72 of file timing.cc.

References gem5::TimingResponseProtocol::recvRespRetry().

Referenced by gem5::RequestPort::sendRetryResp().

◆ sendSnoopResp()

bool gem5::TimingRequestProtocol::sendSnoopResp	(	TimingResponseProtocol *	peer,
		PacketPtr	pkt
	)

protected

Attempt to send a timing snoop response packet to it's peer by calling its corresponding receive function.

If the send does not succeed, as indicated by the return value, then the sender must wait for a recvRetrySnoop at which point it can re-issue a sendTimingSnoopResp.

Parameters

pkt	Packet to send.

◆ trySend()

bool gem5::TimingRequestProtocol::trySend	(	TimingResponseProtocol *	peer,
		PacketPtr	pkt
	)		const

protected

Check if the peer can handle a timing request.

If the send cannot be handled at the moment, as indicated by the return value, then the sender will receive a recvReqRetry at which point it can re-issue a sendTimingReq.

Parameters

peer	Peer to send packet to.
pkt	Packet to send.

Returns: If the send was succesful or not.
