Member Function Documentation
◆ bind()
|
overridevirtual |
Bind this response port to a request port.
This also does the mirror action and binds the request port to the response port as well as binding the base class types.
Reimplemented from gem5::ResponsePort.
Definition at line 89 of file token_port.cc.
References gem5::TokenRequestPort::bind(), fatal, gem5::Port::name(), and tokenRequestPort.
◆ recvRespRetry()

overrideprivatevirtual |
Called by the peer if sendTimingResp was called on this protocol (causing recvTimingResp to be called on the peer) and was unsuccessful.
Implements gem5::TimingResponseProtocol.
