 Slave port. More...
 
virtual ~SlavePort ()
 
Tick sendAtomicSnoop (PacketPtr pkt)

void sendFunctionalSnoop (PacketPtr pkt)
 Send a functional snoop request packet, where the data is instantly updated everywhere in the memory system, without affecting the current state of any block or moving the block. More...
 
bool sendTimingResp (PacketPtr pkt)
 Attempt to send a timing response to the master port by calling its corresponding receive function. More...
 
void sendTimingSnoopReq (PacketPtr pkt)
 Attempt to send a timing snoop request packet to the master port by calling its corresponding receive function. More...
 
void sendRetryReq ()
 Send a retry to the master port that previously attempted a sendTimingReq to this slave port and failed. More...
 
void sendRetrySnoopResp ()
 Send a retry to the master port that previously attempted a sendTimingSnoopResp to this slave port and failed. More...
 
bool isSnooping () const
 Find out if the peer master port is snooping or not. More...
 
void sendRangeChange () const
 Called by the owner to send a range change. More...
