recvRespRetry()

virtual void TimingResponseProtocol::recvRespRetry ( )

protectedpure virtual

Called by the peer if sendTimingResp was called on this protocol (causing recvTimingResp to be called on the peer) and was unsuccessful.

recvTimingSnoopResp()

virtual bool TimingResponseProtocol::recvTimingSnoopResp ( PacketPtr  pkt )

protectedpure virtual

Receive a timing snoop response from the peer.

Implemented in SlavePort, BaseCache::CpuSidePort, CommMonitor::MonitorSlavePort, AddrMapper::MapperSlavePort, MemCheckerMonitor::MonitorSlavePort, sc_gem5::Gem5ToTlmBridge< BITWIDTH >::BridgeSlavePort, CoherentXBar::CoherentXBarSlavePort, MemDelay::SlavePort, and StubSlavePort.

sendResp()

bool 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

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

Returns

If the send was succesful or not.

sendRetryReq()

void TimingResponseProtocol::sendRetryReq ( TimingRequestProtocol *  peer )

protected

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

sendRetrySnoopResp()

void TimingResponseProtocol::sendRetrySnoopResp ( TimingRequestProtocol *  peer )

protected

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

Definition at line 98 of file timing.cc.

References TimingRequestProtocol::recvRetrySnoopResp().

sendSnoopReq()

void 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

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

tryTiming()

virtual bool TimingResponseProtocol::tryTiming ( PacketPtr  pkt )

protectedpure virtual

Availability request from the peer.

Implemented in SlavePort, BaseCache::CpuSidePort, CommMonitor::MonitorSlavePort, sc_gem5::Gem5ToTlmBridge< BITWIDTH >::BridgeSlavePort, and MemDelay::SlavePort.
