DMI dealing with multiple memory

[mohitnegi]

hello ,

 

i have a case where i have to multiple memory which i am accessing using DMI ptr on some particular condtion ..

i have something as below but not sure whether this will work or not ...

bool ufs_model<DATA_TYPE,BUS_WIDTH>::get_direct_mem_ptr(tlm::tlm_generic_payload& trans,tlm::tlm_dmi&  dmi_data){
   
      wait(e_UTRLDBR | e_UTMRLDBR); 
      dmi_data.allow_read_write();
      dmi_data.set_dmi_ptr(reinterpret_cast<unsigned char*>((wait(e_UTRLDBR))?(&utrd_mem[0][0])&utmrd_mem[0][0]));       
      dmi_data.set_start_address(0);
      dmi_data.set_end_address(4*sizeof((wait(e_UTRLDBR))?(utrd_mem)-1):(utmrd_mem-1));   
      return true;
    }

this event is notified from some registers ....

See the 1666-20011 LRM, in particular

 

"o) The implementation of get_direct_mem_ptr shall not call wait, directly or indirectly."

 

So your code is not good :-(
