void | unbind () |
Unbind this master port and the associated slave port. More... | |
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. More... | |
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 bool | isSnooping () const |
Determine if this master port is snooping or not. More... | |
AddrRangeList | getAddrRanges () const |
Get the address ranges of the connected slave port. More... | |
void | printAddr (Addr a) |
Inject a PrintReq for the given address to print the state of that address throughout the memory system. More... | |
