Public Member Functions | |
| MessageSlavePort (const std::string &name, MemObject *owner) | |
| virtual | ~MessageSlavePort () |
 Public Member Functions inherited from SimpleTimingPort | |
| SimpleTimingPort (const std::string &name, MemObject *owner) | |
| Create a new SimpleTimingPort that relies on a packet queue to hold responses, and implements recvTimingReq and recvFunctional through calls to recvAtomic. More... | |
| virtual | ~SimpleTimingPort () |
| Public Member Functions inherited from QueuedSlavePort | |
| QueuedSlavePort (const std::string &name, MemObject *owner, RespPacketQueue &resp_queue, PortID id=InvalidPortID) | |
| Create a QueuedPort with a given name, owner, and a supplied implementation of a packet queue. More... | |
| virtual | ~QueuedSlavePort () |
| void | schedTimingResp (PacketPtr pkt, Tick when, bool force_order=false) |
| Schedule the sending of a timing response. More... | |
| bool | checkFunctional (PacketPtr pkt) |
| Check the list of buffered packets against the supplied functional request. More... | |
| Public Member Functions inherited from SlavePort | |
| SlavePort (const std::string &name, MemObject *owner, PortID id=InvalidPortID) | |
| 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... | |
| virtual AddrRangeList | getAddrRanges () const =0 |
| Get a list of the non-overlapping address ranges the owner is responsible for. More... | |
| Public Member Functions inherited from BaseSlavePort | |
| BaseMasterPort & | getMasterPort () const |
| bool | isConnected () const |
| Public Member Functions inherited from Port | |
| const std::string | name () const |
| Return port name (for DPRINTF). More... | |
| PortID | getId () const |
| Get the port id. More... | |
Protected Member Functions | |

| Implemented using recvAtomic(). More... | |
| bool | recvTimingReq (PacketPtr pkt) |
| Implemented using recvAtomic(). More... | |
| Protected Member Functions inherited from QueuedSlavePort | |
| 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... | |
| Protected Member Functions inherited from SlavePort | |
| void | unbind () |
| Called by the master port to unbind. More... | |
| void | bind (MasterPort &master_port) |
| Called by the master port to bind. More... | |
| virtual bool | recvTimingSnoopResp (PacketPtr pkt) |
| Receive a timing snoop response from the master port. More... | |
