Make gpd a global utility macro for reading config/command line parameters.
Add a corresponding function with full name for clarity, keep the short name
for the macro for backward compatibility and ease of use.
The main benefit of gpd/config_get_paramdef_from_name macro/function is that
it does not require maintaining a separate parameter index list.
1. Create a free_ru_session_list() function to free the memory allocated for the connected RUs
before closing the nr-softmodem.
2. xmlReadMemory() and xmlNodeGetContent() were causing serious memory leakages,
and now all is properly freed using xmlFreeDoc() and xmlFree().
MIMO mode is defined by setting separate carriers to different antenna ports.
Benetel v1.2.2 does not support MIMO mode to be set via M-plane, and therefore
we only created one Tx and one Rx carrier.
Benetel v1.4.1 supports MIMO mode setting via M-plane.
Therefore, this commit introduces the adaptation based on the number of supported carriers by a DUT RU.
These 3 states: "oper-state", "admin-state", "availability-state" are optional,
but shall be checked in order to activate the carriers. If an O-RU doesn't support it,
we assume the expected values:
- "oper-state" = "enabled"
- "admin-state" = "unlocked"
- "availability-state" = "NORMAL"
Implement retrieval of the hardware states if O-RU supports, i.e. Benetel release v1.4.1.
These libraries have an (indirect) dependency on T, either by using the
logging module (which in turn depends on T), or through other includes.
The easiest is to depend on the logging module, which will fulfil also
the T dependency.
It would equally be feasible to use the utils target (which in turn
depends on log_headers), but this would necessitate to compile, and does
not seem to be necessary.
Introduced a parameter start_up_timing which indicates if PM activation is supported during the start-up
procedure. We initialize this parameter, based on the vendor.
Notification interval is set to 10s.
Definition in o-ran-uplane-conf.yang model:
"Gain correction of RF path linked with array element or array layers.
Common part of overall gain_correction.
gain_correction = common array-carrier gain-correction + eAxC gain correction."
- if RU(s) are not well configured, disconnect immediately and stop the DU
- if all RUs are well configured, proceed with waiting until ready. The RU is
ready when the carriers are activated. Either the RU already has preconfigured
carriers (previous M-plane client configured), or the DU has to wait until receives
the notifications.
Ideally, we should load the yang models from the RU operational datastore, but the issues are following:
1) the yang models order is not good - dependancy models have to be loaded first
2) earlier O-RAN yang versions (e.g. v4) is not properly defined (i.e. optional parameters should not be included by default)
Added support in both cases, loading from RU with <get-schema> RPC, and loading statically from "radio/fhi_72/mplane/yang/models" folder.
