      fix rdtsc usage · ad46183e
      Cedric Roux authored
      One user had a problem compiling oaisim.
      This commit fixes it.
      The compilation log was saying:
          In function UE_thread_rxn_txnp4:
          error: inconsistent operand constraints in an asm
               __asm__ volatile ("rdtsc" : "=a" (a), "=d" (d));

      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 ...

      bugfix: intialize memory · 57eef276
      Cedric Roux authored
      This is taken from commit 7bc14347
      and is necessary for the UE to function properly.

      T tracer: don't depend on T_BUFFER_MAX anymore in the tracers · 52cf61de
      Cedric Roux authored
      Whenever the value T_BUFFER_MAX changes, the tracers had to
      be recompiled. The only reason why it was needed is because we
      used some fixed size buffers to read events. This commit removes
      this restriction.
      Also, with the basic simulator, this value T_BUFFER_MAX now comes
      with an #ifdef which would have required some special hackish-level
      tricks in the tracers, which is not good.
      Let's just allocate memory when needed.

      basic simulator: initial release · 6cb04bb4
      Cedric Roux authored
      This commit introduces a 'basic simulator'.
      This basic simulator is made of:
      - the standard eNB code using a special driver that mimics the USRP driver
      - the standard UE code using a special driver that mimics the USRP driver
      - no channel simulation
      - some special code to deal with faster-than-realtime behaviour of this
        basic simulator
      It connects one UE to one eNB. It requires an EPC, populated with the
      correct configuration for the UE.
      This is the initial release and may contain bugs (most probably race
      conditions due to the faster-than-realtime behaviour).
      To use it, see the documentation at:
      It has been tested with 25, 50 and 100 RBs, FDD mode.
      (No check at all has been done to know if it could work in TDD mode.)

      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.

      Summary of changes:
      - some work on better parallel processing of eNB
        try the eNB with options: --fepw --codingw
      - small changes for multi-UE simulation and simulation accuracy
        (UE power levels)
      - initial work for the UE to use TUN device instead of ue_ip.ko
        only done for oaisim, default bearer, compile with:
          ./build_oai --ue-nas-use-tun <rest of options>
