◆ sendBackdoor()

Tick gem5::AtomicRequestProtocol::sendBackdoor ( AtomicResponseProtocol *  peer,
PacketPtr  pkt,
MemBackdoorPtr &  backdoor 
)
protected

Send an atomic request packet like above, but also request a backdoor to the data being accessed.

Parameters
peerPeer to send packet to.
pktPacket to send.
backdoorCan be set to a back door pointer by the target to let caller have direct access to the requested data.
Returns
Estimated latency of access.
