      software/ors-amarisoft: enb/generic: Switch configuration of RU, cell, peer and peercell to shared instances
      
      Previously we had cell_list, ncell_list and peers parameters and we now remove
      them and rework the software release to accept configuration for said objects
      via shared instances. In other words now it is possible to add Radio Units,
      cells, peers and peer cells on on top of main eNB service.
      
      Schema for parameters of those shared instances is based on what we just recently
      generalized and established in ru/ cell/ peer/ and peer/cell/ input schemas. We
      only add cell_kind=enb|enb_peer addition field to be able to distinguish a cell
      from peercell object, and we add a way for cell to reference RU one way or another.
      
      RU-CELL relation is no longer 1-1: one RU can be generally serving multiple
      cells. For example transmission bandwidth of SDR100 board is ~ 100MHz while
      bandwidth of one LTE cell is max 20MHz. This way it is possible to put several
      cells whose frequencies are nearby each other to be run on the same SDR
      board(*). And in general one Radio Unit can be serving transmission/reception in
      multiple frequency ranges, thus providing ability for multiple cells to be
      served by RU. This way RU is split off from CELL object and each CELL needs to
      say which RU object it wants to use.
      
      There are 3 ways to configure CELL->RU links:
      
      1. CELL references a RU object. This is the most general.
      2. CELL embeds definition of RU object. This variant is provided for simplicity
         of management for users that do not want to split CELL/RU relations.
      3. CELL2 references another cell object and says to use the same RU as CELL1.
         Again, this variant is provided for simplicity of management when users want to
         add a cell on top of same RU when they already started with "2".
      
      Full backward compatibility is provided for ORS. For this instance-ors-enb.jinja2.cfg
      is adjusted to inject synthetic RU/CELL/PEER/PEERCELL shared instances instead
      of translating to slapparameter_dict. As the result for ORS users it works
      without visible change as parameters with original ORS schema are handled as expected.
      
      Rendered files for ORS also stay practically the same as before this patch.
      
      The main change is in slaplte.jinja2 - in the loading routines. The other
      changes are mostly straightforward adaptation because details of how ru_dict,
      cell_dict, peer_dict and peercell_dict are loaded were already localized to
      slaplte and the rest of the code independent from that.
      
      Now, once we switched to shared instances, we will be finally able to add tests
      for updated enb. Please see a soon follow-up patch for that.
      
      And for existing test_ors.py we also temporary workaround breakage of tests,
      because currently generic code does not handle well special characters in
      partition references. For example it currently breaks on spaces with buildout
      complaining that sections with spaces in their name are invalid. We will fix
      that in another soon-followup patch as well, but apply a workaround for now.

      software/ors-amarisoft: slapos-render-config: Diverge enb.cfg and ue.cfg generation · dd502ce4
      Kirill Smelkov authored
      The procedures to generate those are currently very similar, and that's why we
      employ a shared `do` function to render them. But enb and ue rendering will
      become different from each other in the next step.
      
      -> Prepare to that by pushing necessary bits of do into do_enb and do_ue insides.
      
      No change in rendered files.

      software/ors-amarisoft: slapos-render-config: Retarget currently generated enb.cfg and gnb.cfg to out/ors/
      
      Besides ORS we will soon add other cases to enb.cfg generation. It will be
      handy to clearly see what is what and to keep ORS case to be also alive and distinguished.
      
      Prepare to that by emitting generated enb.cfg and gnb.cfg to out/ors/enb/ and
      out/ors/gnb instead of just out. Name the file itself enb.cfg always to match
      what happens for real in the SR.
      
      There is no change to generated files - it is only renaming:
      
      ```
      $ ./pythonwitheggs slapos-render-config.py && xdiff config/{old,out}
      ```
      
      ```diff

      software/ors-amarisoft: enb/generic: Switch cell type to be a runtime parameter · 7d5312dc
      Kirill Smelkov authored
      In other words merge enb and gnb into sole enb that can handle both LTE and NR
      cells at the same time and simultaneously.
      
      Previously which type of Radio Access Technology to use - LTE or NR - was
      static parameter of particular software - it was possible to instantiate cells
      only with selected RAT for particular template.
      
      In MultiRU it is 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 cell type to be runtime parameter as the final step to be able to do that.
      
      For generic cell definitions are now required to come with cell_type=lte|nr
      parameter. In schemas cell_list now includes oneOf for lte|nr cell instead of
      particular cell type. Similar adaption is done for ncell_list and
      x2_peers/xn_peers are merged into just peers with similar oneOf.
      
      Global gnb-specific parameters of went-away gnb are also added as global ones to enb:
      
        - gnb_id
        - gnb_id_bits
        - amf_list
        - plmn_list (as plmn_list_5g not to conflict with plmn_list)
        - nssai
      
      They must be present if there are NR cells.
      
      Full backward compatibility is preserved for ORS: now it injects cells to
      generic with particular cell_type annotations and translates ORS-specific
      x2_peers/xn_peers and gnb/plmn_list to proper generic parameters.
      
      In ORS-gnb schema gnb_stats_fetch_period and gnb_drb_stats_enabled had to be
      renamed to enb_stats_fetch_period and enb_drb_stats_enabled, but once again,
      full backward compatibility is preserved because ORS mode already had the
      following in its proxy:
      
          {#- backward compatibility: if ORS is running in gnb mode, and gnb_* parameters
              are present, replace their generic enb_* counterparts with gnb_* ones #}
          ...
      
      The diff for rendered enb.cfg and gnb.cfg, that simulate ORS, before and after
      hereby patch is also empty.

      software/ors-amarisoft: enb: Start to generalize the code to handle multiple peer cells · 2667fd36
      Kirill Smelkov authored
      As with Radio Units and cells organize a registry of peer cells and start to handle
      that registry generally everywhere. The registry is still populated with only
      LTE cells on enb and only NR cells on gnb, but the only place that is aware of
      that is registry loading routine.
      
      In the old code defaults were noticed for tac to be 1 if not provided, and so
      those defaults are pushed to live in ORS now. ORS schemas are also updated
      because that defaults were not declared there.
      
      Generic switches to use peer/cell/lte directly which means that now it accepts
      e_cell_id instead of cell_id as the name for full E-UTRAN cell identity. Full
      backward compatibility is provided for ORS which implements translation of its
      original schema to the new generic one.
      
      Tests will be added later as full tests for generic MultiRU.
      
      Rendered enb.cfg and gnb.cfg change a bit, but the changes are mostly due to
      reordering of fields. The only change with semantic value is
      
          -          ssb_nr_arfcn: ,
          +          ssb_nr_arfcn: 520090,
      
      in gnb.cfg .
      
      The old configuration was invalid anyway because if it is only
      
                    ssb_nr_arfcn: ,
      
      then enb does not start with the following error:
      
          # ../lteenb gnb.cfg
          gnb.cfg:119: unexpected token: ','
      
      Like with many other handover-related fields
      https://tech-academy.amarisoft.com/lteenb.doc#prop.ncell_list.ssb_nr_arfcn
      documents that ssb_nr_arfcn "Must be present" for Inter-gNB HO case. The old
      code was erroneously doing `ncell.get(name, '')` with yielding empty string in
      case a parameter is missing, which is corrected here.

      software/ors-amarisoft: enb/*: Deduplicate ncell_list via peer/cell · 7abb0b52
      Kirill Smelkov authored
      Move schema of peer cells into under peer/cell/lte and peer/cell/nr with
      keeping in mind that peer/cell will become a separate entity in MultiRU.
      
      NR deduplication is straightforward, but for LTE original ncell_list used
      `cell_id` name for full E-UTRAN cell identity. peer/cell/lte uses e_cell_id
      name for that and content of that peer/cell/lte cannot be applied directly to
      ORS's ncell_list and ncell_list in current enb/generic. To keep things working
      we pickup peer/cell/lte field by field with mapping e_cell_id into cell_id. For
      the reference for NR both original ncell_list and new peer/cell/nr use
      nr_cell_id for full 5G cell identity.
      
      Backward compatibility: nothing practically changes for ORS and generic.

      Both software.cfg and software-ors.cfg became trivial wrappers over their bases
      - so move bases to be directly software.

      After previous patch this rendering became unneeded. And after we stop
      render-templates becomes unneeded too, so say goodbye to it as well.

      software/ors-amarisoft: enb+ue: Switch to JSON schemas as the primary source of defaults; stop rendering them
      
      JSON schemas for eNB/gNB and UE specify defaults for many parameters and the
      software release use those defaults when parameters are not explicitly
      specified on the instantiation.
      
      Some primary defaults - for bandwidth and n_antenna DL/UL - were setup in
      render-templates and propagated through all places to avoid duplicating them.
      
      Defaults for many other parameters were duplicated in both JSON schemas and in
      the code that handles those parameters.
      
      To avoid this duplication we either need to extend render-templates and put
      defaults for all the other many parameters there, or just switch to JSON
      schemas to be primary source of those defaults, and use the schemas on
      instantiation by automatically loading them and extracting defaults for all
      parameters from there.
      
      I decided to go the second way because it avoids additional layer of rendering
      and the need to keep on remembering not to put raw defaults in the JSON
      schemas. Evidently this is the same approach that Rapid CDN is going to take
      (see nexedi/slapos!1380 for details).
      
      In this patch we stop rendering JSON schemas and keep their last rendered
      result. In the later patches we will handle formed duplication there and go on
      to further merge enb and gnb.
      
      UE is handled brutally for now, because it will be much reworked after.
      
      Actually loading JSON schemas is left as TODO as I do not have resources to
      implement that now. Still this step is needed as precondition for further
      patches. I hope bit of duplication for enb/gnb parameters is ok, given that
      they are now centrally maintained and corresponding TODO warning is in place.

      software/ors-amarisoft: enb/generic: Tighten defaults · cdc35f9b
      Kirill Smelkov authored
      We currently have 2 kinds of software:
      
      - ORS, whose intended usage is small private networks, and
      - generic, whose intended usage is small-to-medium networks.
      
      and currently they both share defaults for their parameters inherited from ORS.
      But what is appropriate for small private networks, might be not so appropriate
      for medium networks.
      
      For example ORS has default enb_id/gnb_id, but in a network with 100 nodes, it
      is better to force every node to be explicitly assigned an id and error
      otherwise. Similarly for cells ORS has defaults for cell_id, but in network
      with many nodes, cell_id needs to be explicitly assigned. With having a default
      there is also a chance to misspell the parameter name, and do not notice it
      because the software will instantiate without an error but work incorrectly.
      
      So in this patch we tighten the defaults for generic:
      
      - enb_id, mme_list become non-optional for LTE
      - gnb_id, afm_list become non-optional for NR
      - plmn_list becomes non-optional for both LTE and NR. The format is different
        in between RATs and so later we will use plmn_list and plmn_list_5g when
        merging enb and gnb.
      
      - the following parameters of LTE cells now needs to be explicitly configured:
        rf_mode, dl_earfcn, bandwidth, cell_id, pci, tac.
      - the following parameters of  NR cells now needs to be explicitly configured:
        rf_mode, dl_nr_arfcn, nr_band, bandwidth, cell_id, pci.
      
      We rework ORS mode to translate its own set of parameters and defaults into
      generic enb/gnb parameters.
      
      We similarly pull some global generic defaults into instance-enb.cfg.jinja2
      with the idea that they could be maintained in one central place. In the future
      it would be good to automatically load them from JSON schemas to avoid
      duplication.
      
      This patch should be backward compatible for ORS, but it introduces the change
      in cell_id and pci in rendered enb.cfg which become 1 instead of 0:

      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.

      - 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.

      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.

      Previously, e.g. for ORS it was:

      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

      software/ors-amarisoft: Fix json-schemas complain about spaces in software.cfg.json · 0fdff0a0
      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:

      software/ors-amarisoft: enb: Switch RU to be a runtime parameter · 258e38db
      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.

      Kirill Smelkov authored
      Previously rf_mode was static parameter of particular software - it was
      possible to instantiate cells only of the mode selected for particular template.
      
      In MultiRU it will be possible to generally instantiate all kind of cells -

      -> Switch rf_mode to be runtime parameter as a preparatory step for that.
      
      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 · 0fc23eca
      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.

      but default was outside of that enum. The code in enb.jinja2.cfg actually uses
      the first option from the enum as the default.
      
      -> Fix default in schema.
      
      tdd_ul_dl_config in NR seems to be already correct.

      software/ors-amarisoft: ue: Switch UE type to be runtime parameter · 53641314
      Kirill Smelkov authored
      Previously type of emulated UE was static parameter of particular software
      release - it was possible to simulate UE and attach to cells only of the RAT of
      particular template.
      
      In MultiRU it will be possible to generally emulate all kind of UEs - both LTE
      and NR all at the same time, and attach them to LTE and NR cells
      simultaneously.
      
      -> Switch type of UE to be runtime parameter as a preparatory step for that.
      
      URLs of software releases changes (we remove lte and nr in names), but here we
      do not care about backward compatibility because currently there are just a few
      UEsim deployments and migration should be easy.

      SIM card object is useful to have not only for Core Network - we will also use
      it for UE configutation. Move SIM schema into common place as a preparatory step.

      software/ors-amarisoft: ue: Make default K and IMSI to be common for LTE and NR · 6f321938
      Kirill Smelkov authored
      K and IMSI are orthogonal to RAT and, similarly to how we keep default
      n_antenna_dl/ul independent of RAT we can do so with this default UE parameters.
