      software/ors-amarisoft: enb: Set rf_driver.args="---" if no RUs are configured · 9e7c6809
      Kirill Smelkov authored
      Else enb treats args="" unset and implicitly uses /dev/sdr0 by default.
      
      We do not want implicit default behaviour -> we want to see an error.

      software/ors-amarisoft: enb/generic: Do not expose handover measurement config publicly yet · 5b2a2eee
      Kirill Smelkov authored
      We currently have support for a3_offset and a3_time_to_trigger only, while
      there is also a3_hysteresis plus at least a1_*, a2_* and probably other parameters.
      
      Simple A3-only based meas_config tuning might be appropriate for ORS, but for
      generic enb it is better to expose full control which I do not currently feel
      good to implement right now. So do not expose it at all on generic to avoid
      establishing a public API yet.
      
      enb.jinja2.cfg already has corresponding comments:
      
        {#  TODO fully expose lte meas_config_desc in generic SR #}
          meas_config_desc: {
          ...

      software/ors-amarisoft: Start to generalize software.cfg.json · 7d4a76ad
      Kirill Smelkov authored
      - Indicate that it is not for ORS, but for generic case.
      - Move ue to the end, to where it logically belongs.
      - Indicate shared instances clearly with clear visually appearing indent.
        For now it is only about SIM card, but later we will be adding more kinds of
        shared instances, so it will be needed to clearly see on the UR if an item is
        a kind of service, or a shared instance of a service.

      software/ors-amarisoft: Stop autogenerating software*.cfg.json · 681a8d6e
      Kirill Smelkov authored
      There is now only 2 kinds of softwares - ORS and generic, and their cfg.json
      will diverge with ORS staying as it is now for backward compatibility, and
      generic gaining more features and more kind of shared instances. That means
      that it no longer makes sense to render those two from a common source.
      
      -> Stop rendering them and leave previous rendered result in place for further manual edits.

      software/ors-amarisoft: software.cfg.json: Start index from 1, not 0 · ace534b8
      Kirill Smelkov authored
      Previously, e.g. for ORS it was:
      
          enb                 index=0
          gnb                 index=1
          core-network        index=2
          core-network-slave  index=3
      
      which resulted in the following appearance order on SlapOS Master UI:
      
          gnb
          core-network
          core-network-slave
          enb
      
      Note that enb comes last instead of being first as originally intended.
      
      That happens because SlapOS Master treats index=0 as being unset and puts all
      items with unset index in the end.
      
      -> Fix this by starting explicitly-set indices from 1.
      
      Now, for ORS, the order on UI is
      
          enb
          gnb
          core-network
          core-network-slave

      software/ors-amarisoft: Fix json-schemas complain about missing response schemas · 147c9a79

      As explained in the previous patch now once we have software.cfg and
      software.cfg.json, json-schemas started to analyze them instead of skipping
      software/ors-amarisoft/ completely, and it started to complain about missing
      response schemas, for example:

      software/ors-amarisoft: Fix json-schemas complain about spaces in software.cfg.json · 96c4bcf4
      Kirill Smelkov authored
      Previously json-schemas tests were passing on software/ors-amarisoft but the
      status was misleading: since json-schemas check only software.cfg.json, and
      until recently - before the patch to switch RU type to be a runtime parameter,
      there was _no_ such file in here, nothing about software-*.cfg.json was checked at all.
      
      But after the switch we started to have software.cfg and software.cfg.json
      files which json schemas checks and errors start to appear.
      
      Here we fix the following error popping up due to extra blank lines around "ue" entry in software.cfg.json:
      
          FAIL: test_ors-amarisoft_software_cfg_json_format (slapos.test.test_json_schema.TestJSONSchemaValidation)

      software/ors-amarisoft: enb: Switch RU to be a runtime parameter · c4ecf5a0
      Kirill Smelkov authored
      Previously RU type was static parameter of particular software - it was
      possible to instantiate cells only with selected RU type for particular template.
      
      In MultiRU it will be possible to generally instantiate all kind of cells -
      LTE/NR and TDD/FDD all at the same time and each served by a different kind of Radio Unit.
      
      -> Switch RU to be runtime parameter as a preparatory step for that.
      
      There is now only two software releases:
      
        - ORS (software-ors.cfg), and
        - generic (software.cfg).
      
      ORS behaviour stays the same as before here by patch.
      
      For generic each cell in cell_list now needs to explicitly specify which kind
      of RU it wants to use and with which parameters. There are less defaults: for
      example which CPRI board and SFP port to use now needs to be explicitly
      specified.
      
      Only ORS tests are left for now. The old test{LOPCOMM,M2RU,ANY} did not
      exercised any driver-specific functionality and until recently were not run at
      all due to '-' in their file name. We remove them for now and we will add tests
      for generic in a soon follow-up patch after switching LTE/NR cell type to also
      be a runtime parameter.
      
      Backward compatibility:
      
        * nothing changes for ORS
        * for generic all RU-related parameters are now moved from cell_list to
          cell_list.ru, there are several renames and besides ru_type ru_link_type also
          needs to be specified. Please see new RU-related JSON schemas added into
          ru/ for details. Cell_list itself now also does not provide a default with
          one cell - if no cells are configured no cells are instantiated.

      Software for ORS becomes just software-ors.cfg with software-tdd-ors.cfg
      providing backward compatibility proxy as we have many ORS'es currently
      deployed with that software-release URL. For other softwares backward
      compatibility is not preserved including for software-fdd-ors.cfg because we
      practically have very few deployments with those.
      
      To show tdd_ul_dl_config only for TDD we use conditional feature of new JSON-editor.
      
      Backward compatibility: nothing changes for ORS, for everything else rf_mode
      now needs to be explicitly set in cell parameters if it is not TDD.
      
      Rendered enb.cfg and gnb.cfg stay the same.

      software/ors-amarisoft: enb: Start to generalize the code to handle multiple Radio Units · 0a285a34
      Kirill Smelkov authored
      Add code to organize a registry of Radio Units and handle that registry generally everywhere.
      
      RU registry is still populated from cell_list and in practice there still can
      be radio units only of the same type, but besides slaplte.load_ru_and_cell
      which is aware of that, the rest of the code tries to do everything as if
      RUs of different type could be present simultaneously.
      
      Now it is not only lopcomm who can do multiCELL, but also sunwave and SDR as well.
      
      gNB also starts to gain support for cell_list, because cell_list loading is
      uniformly applied to both eNB and gNB. However, since enb.cfg is not yet
      prepared to handle multiple NR cells yet, there is an assert that in case of NR
      there is only one RU/cell present there. We will remove this limitation in a
      follow-up patch.
      
      Later we will also change the loading to load RU descriptions from shared instances
      and they won't be constrained to be Radio Units of the same type. But we need
      to prepare a lot to be able to do that.
      
      One more step forward towards MultiRU.
      
      Tests will be added later as full tests for generic MultiRU.
      
      Backward compatibility: no change for ORS and practically no breaking change for everything else.

      software/ors-amarisoft: enb+ue: Query slapparameter_dict from master only once · 2149bc2d
      Kirill Smelkov authored
      We are currently querying it in instance.cfg and later, once again, in e.g. instance-enb.jinja2.cfg .
      
      However ORS mode will need to adjust slapparameter_dict with ORS defaults
      and pass it further to generic enb. So it won't work if we use
      slapparameter_dict obtained the second time because the second query will
      return unadjusted original slapparameter_dict.
      
      In this patch we are only doing preparatory step - redo the code not query the
      master from instance-{enb,ue}.jinja2.cfg and work with slapparameter_dict and
      slap_configuration already queried by instance.cfg
      
      For UE the change is trivial.
      
      For eNB instance-enb.jinja2.cfg used to set the defaults for com, mme, amf and
      gtp in the same section used for the second query. We rework those defaults to
      be applied to slapparameter_dict via jinja2 - via the same way we are going to
      later use in ORS mode.
      
      Handling defaults for everything besides gtp_addr is straightforward. For
      gtp_addr it has the semantic difference when explicitly given, and given only
      implicitly. In the latter case the intent of original code is to autodetect
      whether to use an address on loopback, or externally-visible address.
      
      Original code used the check for emptiness of mme_list/amf_list as the
      condition for "use loopback". Since now those lists, after applying their
      defaults, are never empty we rework the code to see if core address is on the
      loopback or not, and use auto-GTP-on-loopback only if core is also on loopback.
      This should, hopefully, be more convenient as it also works ok out of the box
      if core is on loopback, but its address was explicitly specified. Previously
      for such cases gtp_addr was also needed to be specified, and now it should work
      without that.
      
      No change to rendered enb.cfg and gnb.cfg besides whitespace.
      
      Adjust ipv6-random usage in core-network for consistency with enb as well.

      instance-enb and instance-ue currently setup that slap_configuration with
      LTE/NR defaults to be accessible from enb.jinja2.cfg and ue.jinja2.cfg. But we
      will soon need to have access to those defaults from slaplte.jinja2 as well,
      and it will break if left as is because when slaplte is imported from e.g.
      enb.jinja2 - it will work, but when slaplte is imported from instance-enb it
      will break because parent of instance-enb (instance.cfg) does not setup
      defaults in slap_configuration at that level.
      
      The fix is to either duplicate slap_configuration at instance.cfg level, or to
      switch access to the defaults to go via original default_* parameters.
      
      We go the second way for simplicity.
