csiim_vars/csirs_vars used to be global array for each UE. Now its present
in phy_data which is in dynamically allocated memory.
MAC config was done without mutex while DL and UL threads could be running
at the same time.
get_ue_nas_info was allocating memory possibly from more than one thread.
Moved it into new init function for UE NAS layer.
Addreses most issues in #869
The goal of this MR is to improve readability, maintainability and consistency
of gNB initialization functions.
This MR is:
- cleaning up redundant and unused code
- refactoring init_gNB, l1_north_init_gNB, RCconfig_NR_L1, NRRCConfig
- removing redundant memory allocation for gNB RAN context and L1 instances
- cleaning up redundant log lines
* the goal of this function is to initialize and configure the RAN Context
* the goal of get_options is to get command line options
* this commit aims at making the implementation more consistent
* move initialization of RC.nb_nr_CC to this function
* cleanup redundant initializations of RC.nb_nr_macrlc_inst outside NRRCConfig
* cleanup redundant initization of RC.nb_nr_macrlc_inst from getter function (get_node_type)
* cleanup RC initialization in RCconfig_NR_L1
* removed redundant log lines (print number of instances in NRRCConfig only)
* do RC init after getting CL options and configuration
* get_node_type shall access configuration only, not RC context
* NRRCConfig shall be called only once: made it thread-safe
* nb_nr_inst represents the number of gNB instances and the number of RAN contexts
* it used also to count the number of RRC instances in the node
* it is set from config file in NRRCConfig, therefore redundant checks after
this function have been removed
* redundant global variable NB_gNB_INST, set after nb_nr_inst, was removed
* gNB and L1 init is done in init_gNB and RCconfig_NR_L1
* moved RCconfig_nr_prs out of create_gNB_tasks for consistency
* do RCconfig_nr_prs only for L1 instances
* removed initialization of gNB
* separate function to get blacklisted UL PRBs
* call the getter in both L1 and MAC/RLC configuration
* other minor improvements

chore(ci): creating a develop tag on top of develop-commit-id tag for the local private registry
Create a 2nd tag of develop for all images on the local registry. We
are doing this in order to simplify cross-repository testing between
FlexRIC and RAN.
Fix two issues with softmodem yaml files
- Fix a typo that prevents casting max_chan to integer in nrue.uicc.yaml
- Remove unused field ssb_PositionsInBurst_PR from gNB example config
yaml file
Fix Regression 4G
- Fix various bugs and/or regressions in 4G code
- Also, the CI does not test RFsim 4G with --sanitize, enables this to
detect problems.
Add Fedora 41, build_oai cleanup
- Add Fedora 41 to list of supported distributions
- Remove some dependencies in RHEL that are not necessary
- Cleanup some build_oai documentation of non-supported options
Simplify logs in gNB&UE
- reduce the amount of printf() that outputs useless info
- in MAC, PHY, NGAP, RRC, mark some "important" UE events with LOG_A for
better visibility -> can put log_config.global_log_level analysis to
only see important stuff
- in RRC, use some macro to consistently print logs
- track the cellID of a UE in RRC
small fix for 3 digit mnc usage in sib1
When 3 digit MNC is used in PLMN, during preparation of SIB1, first
digit of MNC was not taking into account. UE derives Serving Network
Name (SNN) using PLMN info from sib1. Because of 5GCore and UE has
different SNNs, this leads to XRES*, RES* mismatch during Authentication
Procedure between 5GCore and UE. (SNN is used for derivation of these
keys)
Add functional DFT test
- clean up code on (i)dft calls
- add DFT test for some DFT sizes against trivial implementation: it
tests a simple square signal in only real values
- correctly scale DFT-16
