      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
      - 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

      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:
      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

      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

      bugfix for phy simulators (not sure if enough) · 9e4f700a
      Cedric Roux authored
      With the new threading architecture of the UE dlsim
      (and others) does not work properly anymore.
      When looking at the scope, you see a difference
      in PDSCH LLR display. The end is always 0 where
      in the current develop branch (tag 2017.w25) it's not.
      This commit attempts to fix it.
      We still don't have the same behavior as in 2017.w25.
      I disabled channel simulation (so that UE RX = eNB TX)
      and I have one error where in 2017.w25 I have zero.
      For example, here comes the output of a run of "./dlsim":
      **********************SNR = 0.000000 dB (tx_lev 51.000000)**************************
      Errors (1(0)/1000 0/1 0/0 0/0), Pe = (1.000000e-03,0.000000e+00,-nan,-nan), dci_errors 0/1001, Pe = 0.000000e+00 => effective rate 99.900100, normalized delay 0.001472 (1.001000)
      And in 2017.w25 we have (with the same hack to disable
      channel simulation):
      **********************SNR = 0.000000 dB (tx_lev 51.000000)**************************
      Errors (0(0)/1000 0/0 0/0 0/0), Pe = (0.000000e+00,-nan,-nan,-nan), dci_errors 0/1000, Pe = 0.000000e+00 => effective rate 100.000000, normalized delay 0.001471 (1.000000)
      There may be a problem somewhere. Or there was one before and we should
      have had one error and the new UE architecture fixed things and now
      it's as it has to be. Hard to say at this point...
      When looking at the scope we quickly see some zeros for the PDSCH
      LLR, at the begining this time, not at the end. This is just when
      the GUI appears and then all is fine, so this seems to be for the
      first frame only. In 2017.w25 this does not happen.

      - rename UE_NO_LOG to DISABLE_LOG_X
        because the name is misleading. The full software
        is impacted, not only the UE part
      - same for compilation option ---ue-no-log
        that becomes --disable-log
      - keep LOG_X for the standard case, that is the
        case without DISABLE_LOG_X where printf has been
        put. Two reasons:
        * printf is not realtime friendly
        * keep behavior similar for other users who may
          be troubled by different logs that don't add
          any benefit to previous logs

      RRC Rel14 · 4fcb6272
      Cedric Roux authored
      - import RRC ASN.1 defintions from the specifications
        (file openair2/RRC/LITE/MESSAGES/asn1c/ASN1_files/RRC-e10.asn)
        contrary to rel8/10, all modules have been imported, maybe it's too much
        to refine in case of problems
      - deal with rel14 in fix_asn1
      - all code that was for Rel10 is now for Rel10/Rel14
      - some incompatible changes (mostly in naming) were resolved in favor
        of rel14, see in openair2/RRC/LITE/defs.h
      - unsure about the rlc layer, some arrays have changed (values appended),
        I only changed the definition and in tests in the code, I changed
        the index limit, maybe it's not enough
      Rel14 is the default compilation mode.
