virtual | ~SMMUControlPort () |
Public Member Functions inherited from gem5::SimpleTimingPort | |
SimpleTimingPort (const std::string &name, SimObject *owner) | |
Create a new SimpleTimingPort that relies on a packet queue to hold responses, and implements recvTimingReq and recvFunctional through calls to recvAtomic. | |
virtual | ~SimpleTimingPort () |
Public Member Functions inherited from gem5::QueuedResponsePort | |
QueuedResponsePort (const std::string &name, RespPacketQueue &resp_queue, PortID id=InvalidPortID) | |
Create a QueuedPort with a given name, owner, and a supplied implementation of a packet queue. | |
virtual | ~QueuedResponsePort () |
void | schedTimingResp (PacketPtr pkt, Tick when) |
Schedule the sending of a timing response. | |
bool | trySatisfyFunctional (PacketPtr pkt) |
Check the list of buffered packets against the supplied functional request. | |
Public Member Functions inherited from gem5::ResponsePort | |

Find out if the peer request port is snooping or not. | |
void | sendRangeChange () const |
Called by the owner to send a range change. | |
void | unbind () override |
We let the request port do the work, so these don't do anything. | |
void | bind (Port &peer) override |
Attach to a peer port. | |
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. | |
void | sendFunctionalSnoop (PacketPtr pkt) const |
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. | |
bool | sendTimingResp (PacketPtr pkt) |
Attempt to send a timing response to the request port by calling its corresponding receive function. | |
void | sendTimingSnoopReq (PacketPtr pkt) |
Attempt to send a timing snoop request packet to the request port by calling its corresponding receive function. | |
void | sendRetryReq () |
Send a retry to the request port that previously attempted a sendTimingReq to this response port and failed. | |
void | sendRetrySnoopResp () |
Send a retry to the request port that previously attempted a sendTimingSnoopResp to this response port and failed. | |

Port & | getPeer () |
Return a reference to this port's peer. | |
const std::string | name () const |
Return port name (for DPRINTF). | |
PortID | getId () const |
Get the port id. | |
bool | isConnected () const |
Is this port currently connected to a peer? | |
