SYS_NICE is a capability that allows a process to set thread affinity and priority, among other things (see capabilities(7) for more info). In this commit, add a function that allows to determine if the process has this capability, and try to change the thread affinity and priority, if requested. If the capability does not exist, the function will simply not attempt to change the corresponding thread attributes. To determine if the process has SYS_NICE, libcap can be used. However, it might not be installed by default. To avoid requiring another dependency, if we detect that libcap is not present, use a workaround by try to set a real-time scheduling policy; if it's present, or can be changed, we assume that the process has SYS_NICE (and clean up, if relevant). Simplify reading of capabilities

set_latency_target() attempts to set keep "low latency" by - writing a specific latency to /dev/cpu_dma_latency - setting manually the minimum CPU processor frequency to be the maximum There is no functionality to undo this after stopping the softmodem(s), and most users are probably not even aware that OAI does this. It is generally preferable to set this beforehand using a governor or by disabling sleep states (as outlined in the tutorial, and in a follow-up commit in the performance tuning docs). The previous mlockall() call, to lock memory to RAM, is retained in a new function. There were additional mlockall() calls, which have been replaced with lock_memory_to_ram(), where necessary.

There is already a command line option called 'ue-scan-carrier' which seemed to blindly look for SSB by changing the center frequency by +/-100Hz if the previous attempt failed. This is probably copied from LTE and is not suitable for NR. This commit uses this option to either 1. Perform initial sync on one GSCN if the SSB position if known 2. Or scan the all GSCN (if the SSB postion is unknown) Also, the following is done for re-synchronization 1. Scan all GSCN when UE comes back from IDLE state 2. Scan one GSCN when UE does re-estabishment Removed dependency of lte-softmodem.h in nr-softmodem.c. CONFIG_HLP_UESCAN is declared also in lte-softmodem.h.

They use 4G NUMBER_OF_UE_MAX, which is not supposed to be present in 5G. Further, the mutex and variable are global state; for Paging, we should use F1.

This commit introduces an additional (implicit) option that signals if the E2 agent is to be activated or not. When reading the configuration, we now check if all fields are set, and activate the E2 agent only if this is the case. If not, we only print a warning and start the gNB without the agent. Note that previously, if not all fields are set correctly, the gNB stopped. To implement this behavior, it is necessary to change the defaults of the RIC IP and the directory for SMs to a (non-NULL) default value. Otherwise, the configuration system would not consider the field to be set to the default, and wrongly assumes the field is set, even though it is not; at least, this change is necessary to make config_isparamset() return NULL if the configuration is not set.

3GPP has the concept of a gNB-CU-UP ID and a (separate) gNB ID (for gNB, CU-CP). This commit introduces the gNB-CU-UP as a separate ID that has to be set in the configuration file when running as a CU-UP. For the CU/monolithic gNB, it is optional (but needs to be the same as the gNB-ID if specified). The CU-UP ID is necessary, as some entities, e.g., the e2 agent, need to signal both IDs, e.g., to reconcile a CU-CP and (multiple) CU-UP(s) belonging together.

The E1AP Setup Request contained the network configuration (IP address, ports) as well as the actual E1AP Setup Request application data (Supported PLMNs, ...). This has the drawbacks that - The E1AP Setup Request is stored to retrieve IP addresses in the E1AP module, which is confusing as the Setup Request, per standard, has no IP info - The CU-CP received an E1 Setup Request for configuration during start up, but it did not actually receive such Setup Request, but merely the IP configuration to set up the socket This commit splits the E1AP Setup Request into a "real" Setup Request for application data, and creates a new type e1ap_net_config_t to group all IP configuration data. Further, a new ITTI message type E1AP_REGISTER_REQ is introduced to group both types. What happens is - RCconfig_NR_CU_E1() reads both E1AP application-level data and IP configuration, as previously - The data is sent to the CU-CP. It discards the E1AP Setup Request data, and only uses the network configuration to set up the socket - The data is sent to the CU-UP. It uses the network configuration to connect to the CU-CP, and then sends the E1AP Setup Request to the CU-CP. Currently, the CU-CP still stores the Setup Request locally, which will be changed in the next commit to send it to the RRC.

Use a struct to initialize the RRC at the beginning, and remove the NRRRC_CONFIGURATION_REQ. This message is not necessary; the RRC/CU should be initialized from the F1 Setup Request, coming from the DU.

- move following radios: AW2S, BladeRF, IRIS, LMSSDR, RFsimulator, USRP - move following transports: Ethernet, benetel4g, benetel5g - for each: create independent cmake variable to switch compilation on/off, in order: OAI_AW2S, OAI_BLADERF, OAI_IRIS, OAI_LMSSDR, OAI_SIMU, OAI_USRP, OAI_ETHERNET, OAI_BENETEL4G, OAI_BENETEL5G - Remove RF_BOARD variable, allows to compile multiple boards at once - where applicable: remove USERSPACE/LIB in path, i.e., move files up to directories, as all are userspace libraries Note that with the above, it is now mandatory to enable a radio implementation before compiling it, e.g., for USRP: ./build_oai -w USRP cmake .. -DOAI_USRP=ON && ninja oai_usrpdevif

In the UE, we wish to handle ^C in the UE to send a message before terminating, so we allow custom wait handlers to implement such functionality. Use itti_wait_tasks_unblock() to unblock itti_wait_tasks_end(). Also, implement itti_wait_tasks_end() using semaphores, as signals are not async-signal-safe (and therefore should not be used in a signal handler).
