      T: add a 'multi' tracer · fdd4366d
      Cedric Roux authored
      This tracer allows the connection of several tracers to one tracee.
      
      To use the multi tracer:
      - run the tracee as usual, eg. ./lte-softmodem -O xxxx.conf --T_stdout 0
      - run the multi tracer: ./multi -d ../T_messages.txt
      - connect other tracers to the multi tracer:
         - ./enb -d ../T_messages.txt -p 2022
         - ./textlog -d ../T_messages.txt -p 2022
         - etc.
      
      By default the multi tracer connects to the tracee to the port 2021,
      as for any other tracer.
      
      Then it accepts connections from other tracers on the port 2022.
      
      This can be changed with parameters on the command line.
      
      The tracee and the other tracers can be stopped/started at any time.

      Later on, use this file with gtkwave.
      To be used to check realtime behaviour of the system.

      T: add a tracer: extract · 6322010e
      Cedric Roux authored
      This tracer extracts the content of a buffer field of an event
      that was previously saved using the tracer 'record'.
      
      For example, to extract the channel estimation done in
      frame 924 and subframe 2 as saved in the file input_record.raw
      and to store it in the file output.raw, do:
      
      ./extract -d ../T_messages.txt -o output.raw input_record.raw ENB_PHY_UL_CHANNEL_ESTIMATE chest_t -f frame 924 -f subframe 2

      T: add a mac pdu -> wireshark replay tracer · 8b732dc7
      Cedric Roux authored
      This tracer takes the traces ENB_MAC_UE_DL_PDU_WITH_DATA
      and ENB_MAC_UE_UL_PDU_WITH_DATA from a trace file
      (as generated by the "record" tracer) and sends them
      in UDP packets correctly formatted for wireshark to
      dissect them.
      
      One unresolved problem I face with my version of
      wireshark (1.10.6) is that I don't get the frame number,
      only subframe. See in the code to change the behavior
      if you use a more recent version of wireshark.
      
      You need to properly configure wireshark for it to work.
      See $OPENAIR_DIR/openair2/UTIL/OPT/README.txt.
