| Slave port. More... | |
| virtual | ~SlavePort () |
| Tick | sendAtomicSnoop (PacketPtr pkt) |
| Send an atomic snoop request packet, where the data is moved and the state is updated in zero time, without interleaving with other memory accesses. More... | |
| 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... | |

| bool | recvTimingReq (PacketPtr pkt) |
| Receive a timing request from the master port. More... | |
| void | recvRespRetry () |
| Called by the master port if sendTimingResp was called on this slave port (causing recvTimingResp to be called on the master port) and was unsuccesful. More... | |
| AddrRangeList | getAddrRanges () const |
