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. -------- Appendix.
