Hello, No. You should not have a response for WritebackDirty. In fact, most (all?) writes do not have responses. See src/mem/packet.cc. ( https://gem5.googlesource.com/public/gem5/+/master/src/mem/packet.cc#80) Some commands have the "NeedsResponse" flag set. If so, this request will be turned into a response by whatever memory object fulfills the request (by calling pkt.makeResponse()).
I hope this answers your question.
