RequestPort (const std::string &name, SimObject *_owner, PortID id=InvalidPortID) | |
Request port. | |
RequestPort (const std::string &name, PortID id=InvalidPortID) | |
virtual | ~RequestPort () |
void | bind (Port &peer) override |
Bind this request port to a response port. | |
void | unbind () override |
Unbind this request port and the associated response port. | |
virtual bool | isSnooping () const |
Determine if this request port is snooping or not. | |
AddrRangeList | getAddrRanges () const |
Get the address ranges of the connected responder port. | |
void | printAddr (Addr a) |
Inject a PrintReq for the given address to print the state of that address throughout the memory system. | |
Tick | sendAtomic (PacketPtr pkt) |
Send an atomic request packet, where the data is moved and the state is updated in zero time, without interleaving with other memory accesses. | |
Tick | sendAtomicBackdoor (PacketPtr pkt, MemBackdoorPtr &backdoor) |
Send an atomic request packet like above, but also request a backdoor to the data being accessed. | |
void | sendFunctional (PacketPtr pkt) const |
Send a functional 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. | |
void | sendMemBackdoorReq (const MemBackdoorReq &req, MemBackdoorPtr &backdoor) |
Send a request for a back door to a range of memory. | |
bool | sendTimingReq (PacketPtr pkt) |
Attempt to send a timing request to the responder port by calling its corresponding receive function. | |
bool | tryTiming (PacketPtr pkt) const |
Check if the responder can handle a timing request. | |
bool | sendTimingSnoopResp (PacketPtr pkt) |
Attempt to send a timing snoop response packet to the response port by calling its corresponding receive function. | |
virtual void | sendRetryResp () |
Send a retry to the response port that previously attempted a sendTimingResp to this request port and failed. | |
![]() | |
virtual | ~Port () |
Virtual destructor due to inheritance. | |
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? | |
void | takeOverFrom (Port *old) |
A utility function to make it easier to swap out ports. | |
Protected Member Functions | |
virtual bool | recvTimingResp (PacketPtr pkt) |
Receive a timing response from the peer. | |
virtual void | recvReqRetry () |

void | recvTimingSnoopReq (PacketPtr pkt) override |
Receive a timing snoop request from the peer. | |
void | recvRetrySnoopResp () override |
Called by the peer if sendTimingSnoopResp was called on this protocol (causing recvTimingSnoopResp to be called on the peer) and was unsuccessful. | |
