      Fix NFAPI integration · 922b5b59
      Cedric Roux authored
      This commit fixes issues introduced by the previous commit.
      
      Summary of work:
      - cleanup:
        - fix LOG_XX to be less verbose
        - fix cmake_targets/CMakeLists.txt
        - fix oaienv
        - remove dead code
      - bug fixes:
        - in openair1/SCHED/fapi_l1.c we had:
            eNB->pdcch_vars[subframe&1].num_dci           = number_dci;
          should be:
            eNB->pdcch_vars[subframe&1].num_dci           = 0;
          This bug let the PHY send more DCIs than what should have been
          sent because num_dci is incremented later on in the code.
          This fix may be a problem for fapi mode, to be checked.
        - add new T VCD traces
        - revert openair1/PHY/TOOLS/file_output.c to 'develop' version
        - remove thread_id in logRecord/logRecord_mt
        - revert (and adapt) configuration files
        - be careful when doing frame++, we need to % 1024
        - revert target_rx_power in openair2/LAYER2/MAC/eNB_scheduler_ulsch.c
      - NFAPI:
        - the open-nFAPI code has been included in the repository. See nfapi/README.
          Maybe we should "git clone" the Cisco repository instead. We have to be
          careful of availability though.
      
      What has been tested:
      - monolithic eNB FDD 5/10MHz with one UE, iperf UDP/TCP uplink/downlink
      
      Anything else may fail to work, especially the FAPI mode, which has not
      been tested at all.

      import NFAPI work from David Price from Cisco (non-working commit, do not use it) · 7757b9e7
      Cedric Roux authored
      It has been chosen to not include the full history of commits
      from David. He included a binary version of wireshark, probably
      a modified one that understands NFAPI. Wireshark is released under
      the GPL license, we cannot include it in the repository. We could
      have done a next commit to remove this binary. But then it would
      still be present in the history of commits, which may not be allowed.
      And it would take space on disk. We could edit the history to remove
      wireshark entirely. But this operation is too complicated.
      
      There was also a pcap capture file, which has nothing to do in
      the history of commits and would take space on disk. There again,
      it's too difficult to edit the history to remove it.
      
      There was a file .gitignore that was also removed.
      
      The original history can be found on David's repository:
      https://gitlab.eurecom.fr/daveprice/openairinterface5g/
      The branch is: nfapi-ru-rau-split.
      
      A copy of that branch has been included in the internal OAI
      repository, for those who have access to it.
      The branch is the same. The last commit ID is
      91064382.
      
      You can compare the current commit with the commit 9106...
      to see what differs.
      
      The current commit has to be considered non-working.
      The commit following the current commit will fix problems with
      the work in the current commit.
      
      If you use git bisect, don't spend time analyzing the current
      commit.

      mobipass standalone driver · c866677a
      Cedric Roux authored
      How to use:
      
      1 - compilation of softmodem:
        ./build_oai --eNB -t ETHERNET
      
      2 - compilation of mobipass driver:
        cd cmake_targets/lte_build_oai/build
        make oai_mobipass
        ln -sf liboai_mobipass.so liboai_transpro.so
      
      3 - configuration:
        edit the configuration file, set "node_timing" to
        "synch_to_mobipass_standalone"
        that is, have the line:
          node_timing               = "synch_to_mobipass_standalone";
      
      4 - run:
        run as usual: sudo ./lte-softmodem -C <configuration file>

      bladerf: tentative to have it functional · 0da60274
      Cedric Roux authored
      Several problems are present.
      
      The first is that _write returns 0 instead of the
      number of samples. We solve it by returning
      nsamps.
      
      The second is that _read may return less samples at
      the beginning and we don't want to exit for that.
      We solve it also by returning nsamps.
      (We still need to log more in this, to be done in the
      next commit.)
      
      The third is that after initialization we don't send
      anything for a while, time for the softmodem to finish
      its init. This generates lots of "RX overrun".
      We solve it by disabling TX and RX modules after init
      and then in trx_brf_start we activate them again (and
      also call bladerf_sync_config, which seems to be
      mandatory, and bladerf_calibrate_dc, which may be avoided,
      perhaps).
      
      Maybe not the end of the story. Sometimes it works, UE connects,
      traffic is fine (tested only with 5MHz). Sometimes it does not,
      UE does not connect, or it connects but then traffic is bad,
      especially uplink.
      
      To be refined.

      bugfix: workaround a problem with timestamp and LMSSDR. · fa0b8668
      Cedric Roux authored
      We have a strange problem with the timestamp of the very
      first packets received from the LimeSDR that leads to
      a complete failure of the eNB.
      
      A simple workaround is to discard the first RX packet
      just after a "start" of the device.
      
      We also change the value of "tx_sample_advance" to a more
      reasonable value. The problem of timestamp was "solved"
      differently in the past and at the time we needed to put
      a much higher value.
      
      This may have to be refined at some point.
