      hotfix: protobuf-c compilation failure · 17b9a9e9
      Cedric Roux authored
      protobuf-c does not compile anymore.
      Let's handle this a bit better.
      We now install protobuf and protobuf-c only for the
      flexran agent. That is, if you want to use the flexran
      agent, you need to install protobuf/protobuf-c and
      you do it this way:
        ./build_oai -I -a
      (you add -a)
      Other targets don't need protobuf nor protobuf-c, so
      it's not installed by the -I command of build_oai,
      unless you pass -a with -I.
      Also, we now use protobuf 3.3.0, not 2.6.1. The code
      has been adapted, a quick test seems to indicate that
      the system works, but it has not been intensively tested.

      Merge branch 'develop_integration_w30' into 'develop' · f7466b0e
      Cedric Roux authored
      Summary of changes:
      - UE: new thread idx
      - UE: Pdcch optim
      - UE: slot0 slot1 parallelization
      - bugfixes for RLC AM (see gitlab issue 250)
      - fix bug "unknown UE_id for rnti"
      Note: due to the new UE threading architecture,
      oaisim and the phy simulators may not work properly
      anymore. Adaptation in the code has been done, automatic
      tests seem to pass, but it may not be enough.

      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.

      bugfix: fix sync for oaisim · 030a3452
      Cedric Roux authored
      With the current implementation of oaisim
      (rxdata and channel simulation), we cannot
      call trx_read_func on a dummy buffer. The
      code will actually modify the rxdata buffers
      of the UE.
      This is has to be rewritten properly. In the
      meantime, let's introduce a simple hack. The
      idea of the read at this point is to wait for
      the synch to finish and not lose samples from
      the hardware in the real UE. In the simulator,
      as it is today, we can simply sleep until the
      synch code has finished its work.

      integration fix: let oaisim work again · 3ed32a77
      Cedric Roux authored
      In case of oaisim, dl_phy_sync_success has to be called
      by initial_sync, as it used to be.
      We introduce an #if OAISIM, this is not elegant, but will
      do it for the moment.
