      cleanup - remove unnecessary calls to get_cpu_freq_GHz · 5a61f994
      Cedric Roux authored
      The one in lte-enb.c disrupts the realtime. Using a B200mini with
      20MHz bandwidth leads to the UE unable to connect for it seesms like
      the UL and DL are not properly time synched because of this sleep
      of one second that happens after the USRP streaming has started.
      We see some random access attempts but the decoded preamble is
      wrong.
      
      This may be dependant on the setup. I had sporadic errors with
      a B210, where sometimes the UE could connect and sometimes not.

      free memory when stopping/restarting lte-softmodem · d0922311
      Robert Schmidt authored
      - add function free_td() -> complements init_td() [seems to not be used, added
        for completeness]
      - add function free_td8() -> undoes init_td8() [free memory of 8-bit LLR Turbo
        decoder]
      - add function free_td16() -> undoes init_td16() [free memory of 16-bit LLR
        Turbo decoder]
      - change function free_tdavx216() -> undoes init_tdavx216() [free memory of
        16-bit LLR Turbo decoder, AVX2 version]
      - add free_lte_top() -> frees memory allocated by init_lte_top()
      - change free_ul_ref_sigs() to set freed pointers to NULL
      - add method free_transport() -> frees memory of ULSCH/DLSCH transport channels
      - use the above functions when stopping/restarting the lte-softmodem

      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.

      L1/L2 scheduling extensions for BL/CE operation, BR random-access procedure, BR PRACH detection. Still untested, but compilation succeeds. Missing elements in L2 - PUSCH programming for Msg3, Msg4 retransmission programming for BL/CE. DLSCH/ULSCH programming for UE-specific DLSCH/ULSCH for BL/CE
