In reality, most of the stepping is done by the callbacks on the LSQ but this function is responsible for issuing memory requests lodged in the requests queue.

LSQQueue Minor::LSQ::requests

requests contains LSQRequests which have been issued to the TLB by calling ExecContext::readMem/writeMem (which in turn calls LSQ::pushRequest and LSQRequest::startAddrTranslation).

Once they have a physical address, requests at the head of requests can be issued to the memory system. At this stage, it cannot be clear that memory accesses must happen (that there are no preceding faults or changes of flow of control) and so only cacheable reads are issued to memory. Cacheable stores are not issued at all (and just pass through 'transfers' in order) and all other transfers are stalled in requests until their corresponding instructions are at the head of the inMemInsts instruction queue and have the right streamSeqNum.
