Hi, ARM ldrex instruction use LoadLockedReq (mem/packet.cc) in GEM5. If I am not wrong, according to ARM document, ldrex will make cache line in exclusive state. But LoadLockedReq does NOT have NeedsExclusive attribute now. does LoadLockedReq packet miss NeedsExclusive attribute or should ldrex use another type packet?
Thanks! Zhiguo
