void | sendFunctional (PacketPtr pkt) |
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. More... | |
bool | sendTimingReq (PacketPtr pkt) |
Attempt to send a timing request to the slave port by calling its corresponding receive function. More... | |
bool | sendTimingSnoopResp (PacketPtr pkt) |
Attempt to send a timing snoop response packet to the slave port by calling its corresponding receive function. More... | |
virtual void | sendRetryResp () |
Send a retry to the slave port that previously attempted a sendTimingResp to this master port and failed. More... | |
AddrRangeList | getAddrRanges () const |
Get the address ranges of the connected slave port. More... | |
void | printAddr (Addr a) |
