[gem5-users] A question/possible bug in cache coherence protocol of MOESI_hammer

[GE ZHIGUO]

In the file MOESI_hammer-cache.sm, should the following transition be changed?

   transition(MM, Other_GETS, I) {
    c_sendExclusiveData;
    l_popForwardQueue;
  }

The above transition should be changed to:

  transition(MM, Other_GETS, O) {
    ee_sendDataShared;
    l_popForwardQueue;
  }


Thanks!
Zhiguo
