  1. So I'm trying to send tlm_generic_payload over peq_with_get, and it's not really working as it should. I have three functions that I need to "pass" with this, and when I prinout the address of pointer to tlm_generic_payload, its always the same, which seems like a good thing, but when I print out address of payload->get_data_ptr() its always rubbish, and not constant. Code: class Chiplet : public sc_core::sc_module { public: // The TLM socket to send bus traffic. tlm_utils::simple_initiator_socket<Chiplet> chipletWLSocketMaster[WAVELINK_SOCKETS]; // The TLM socket to receive bus traffic. tlm_utils::simple_target_socket_tagged<Chiplet> chipletWLSocketSlave[WAVELINK_SOCKETS]; Chiplet( sc_core::sc_module_name name, sc_in_clk* systemClock ); ~Chiplet(); void recvTransfer(int id, tlm::tlm_generic_payload &payload, sc_core::sc_time &delay); //callback for receiving b_transfer private: void doit_send( void ); SEND_ERR_CODES sendTransferSpawn(tlm::tlm_generic_payload* payload); tlm_utils::peq_with_get<tlm::tlm_generic_payload>* send_peq; sc_event startSendTransfer_ev; }; Chiplet::Chiplet(sc_core::sc_module_name name, sc_in_clk* systemClock) : _name(name) { SC_HAS_PROCESS(Chiplet); clk(*systemClock); for(int i = 0; i < WAVELINK_SOCKETS; i++) { chipletWLSocketSlave[i].register_b_transport( this, &Chiplet::recvTransfer, i ); } send_peq = new tlm_utils::peq_with_get<tlm::tlm_generic_payload>("send_queue"); SC_THREAD(doit_send); } SEND_ERR_CODES Chiplet::prepareFrame(/*all parameters needed for payload fields*/ ) tlm::tlm_generic_payload *payload = new tlm::tlm_generic_payload; payload->set_address(offset); payload->set_command(tlm::TLM_WRITE_COMMAND); payload->set_data_ptr(send_ptr); payload->set_data_length(sizeof(EthernetFrame) + length); cout << "payload addr 1 " << payload/*->get_data_ptr()*/ << endl; send_peq->notify(*payload, (ZERO_DELAY, dummy_delay)); //after N of these payloads has been added to send_peq, startSendTransfer_ev is triggered and we move on to the next function } void Chiplet::doit_send( void ) { tlm::tlm_generic_payload *payload; while(1) { wait(startSendTransfer_ev); while(payload = send_peq->get_next_transaction()) { cout << "payload addr 2 " << payload/*->get_data_ptr()*/ << endl; sc_spawn( sc_bind(&Chiplet::sendTransferSpawn, this, payload) ); } } } SEND_ERR_CODES Chiplet::sendTransferSpawn(tlm::tlm_generic_payload* payload) { cout << "payload addr 3 " << payload/*->get_data_ptr()*/ << endl; //b_transfer would be invoked from here } So, as I said, these printouts always give the same address for 1st payload (payload addr 1 = payload addr 2 = payload addr 3), and same address for 2nd payload, and same address for N-th payload. But, if I try to print with payload->get_data_ptr() all I get is rubbish. What am I missing? EDIT> Found an error, on part of code not shown here there was some static memory allocation that had to be dynamic. Feel free to delete / not approve this thread.
