Hi all:
I am a newer to GEM5 simulator. I want to get the exact memory data stored
in the simulated system. I have noted that there is a function
AbstractMemory::access(PacketPtr pkt) in abstract_mem.cc.
if (pkt->isRead()) {
assert(!pkt->isWrite());
if (pkt->isLLSC()) {
trackLoadLocked(pkt);
}
if (pmemAddr)
memcpy(pkt->getPtr<uint8_t>(), hostAddr, pkt->getSize());
TRACE_PACKET(pkt->req->isInstFetch() ? "IFetch" : "Read");
numReads[pkt->req->masterId()]++;
bytesRead[pkt->req->masterId()] += pkt->getSize();
if (pkt->req->isInstFetch())
bytesInstRead[pkt->req->masterId()] += pkt->getSize();
} else if (pkt->isWrite()) {
if (writeOK(pkt)) {
if (pmemAddr)
memcpy(hostAddr, pkt->getPtr<uint8_t>(), pkt->getSize());
I guess that, the exact operation of memcpy() is to read (write) data from
(into) the memory in case of read (write) operations (indicated by
pkt->isWrite()). Am I right here?
Regards,
Shuchang
