◆ sendResp()

bool gem5::TimingResponseProtocol::sendResp ( TimingRequestProtocol peer,
PacketPtr  pkt 
)
protected

Attempt to send a timing response 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 recvRespRetry at which point it can re-issue a sendTimingResp.

Parameters
peerPeer to send the packet to.
pktPacket to send.
Returns
If the send was succesful or not.

◆ sendRetryReq()

void gem5::TimingResponseProtocol::sendRetryReq ( TimingRequestProtocol peer)

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

◆ sendRetrySnoopResp()

void gem5::TimingResponseProtocol::sendRetrySnoopResp ( TimingRequestProtocol peer)

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

◆ sendSnoopReq()

void gem5::TimingResponseProtocol::sendSnoopReq ( TimingRequestProtocol peer,
PacketPtr  pkt 
)
protected

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

Snoop requests always succeed and hence no return value is needed.

Parameters
peerPeer to send the packet to.
pktPacket to send.
