      import work from the branch nfapi-L2-emulator to merge it to develop · f254107b
      Cedric Roux authored
      It was not possible to merge the branch directly, because the
      history of this branch contains files that cannot be in the
      repository, namely wireshark from Cisco work on nFAPI.
      
      As for Cisco work on nFAPI, a special commit containing all the
      work is thus created.
      
      Below is the output of the command:
      git log --graph 184d51c6..61276d87
      
      184d51c6 is the commit ID of the develop
      branch prior to the merge.
      
      61276d87 is the commit ID of the
      nfapi-L2-emulator branch prior to the merge.
      
      The commit 61276d87 (and all its
      history) will be removed from the main OAI repository. It is
      present in the internal OAI repository for those who have access
      to it.
      
      There was also some cleanup done on the code.
      
      Some changes were necessary to have the eNB functional. They may have an
      impact on the FAPI ...

      Compare version number using MAKE_VERSION macro to provide better SW configuration: · 5c23af77
      Bi-Ruei, Chiu authored and Cedric Roux's avatar Cedric Roux committed
      1. Previous SW configuration for different RRC version relies on whether macro Rel10,
         Rel14 defined or not by checking #ifdef Rel14 or #if defined(Rel10) || defined(R14).
         Whenever there is a newer RRC version, e.g. Rel15, it will be very a tedious and
         error-prone job to add defined(Rel15) in every place.
      
      2. Some RRC messages are defined in release 13 instead of release 14, NB-IoT
         feature is one of such example. Our code shall reflect this fact instead of using
         an afterward version number in software configuration.
      
      3. Some RRC messages or some fields of certain RRC messages are added in the middle
         a release, e.g. SystemInformationBlockType1_v1310_IEs_t defined in RRC 13.1.0
         and RRC 9.2.0 made some changes to SIB12 and SIB13 so we have sib12_v920 and
         sib13_v920 fields in SIB12 and SIB13's struct.
         We need a finer grain of control when using ASN1 from different RRC version.
      
      4. S1AP also has this problem that it use UPDATE_RELEASE_9 and UPDATE_RELEASE_10 to
         differentiate between various S1AP version.
      
      This commit propose using MAKE_VERSION(x,y,z) to designate the version number and
      modify current conditional compilation accordingly.
      
      Note: 2018/04/16, Modified based on Cedric's comment.

      cleanup MAC PDU generation (plus some general cleanup) · 1a8d81ba
      Cedric Roux authored
      The code was very unclear and potentially buggy.
      This new version is more robust.
      
      We can waste up to 2 bytes because the last header in the MAC PDU
      does not contain a length field and when we request data from RLC
      we suppose a 3-bytes MAC header. This might be optimized at some
      point, but the benefit would be low.
      
      This commit also contains some general cleanup:
      - formatting
      - variables' types: let's use 'int' instead of trying to be clever
        by using small types that may generate bugs if the value is
        too big
      - remove 'tpc_accumulated' which was globally used for all UEs
        and has no purpose other than logging. We may want to rework
        a bit the TPC machinery at some point. As the code is today
        we may repeatedly send TPC over and over without caring about
        the 3GPP limits, in which case no one knows how the UE is
        supposed to behave: does it clamp the current max value or does
        it accumulate over and over and take the clamped value to compute
        its actual power? If we send a reverse TPC (reduce power instead
        of increase) does it do it immediately or does it have to decrease
        n+1 times if we previously ordered it to increase n times?)
      
      We do not address the problem of prioritizing LCIDs. As of today there
      is only one dedicated traffic channel (DTCH), so it's not a problem
      at this point.
      
      What has been tested:
      - monolithic eNB 5/10/20MHz with one cots UE, TCP/UDP UL/DL. At 20MHz the
        machine used was not capable of keeping up, generating lots of Us
        and Ls when the throughput reaches 60Mb/s. USRP B210 was used.

      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.
