The offset provided for each code block in the HARQ combined input and output buffer shall not be above 512.
A modulus was performed on the offset of the TB in the buffer to avoid this situation.
But the offset of the code block was added afterward so that the total offset was sometimes going above 512.
This commit performs the modulus after adding the code block offset.
Modify xu_add_f1_ue_data() to be xu_addmod_f1_ue_data(), i.e., "addmod"
behavior in which it is possible to also update f1_ue_data. I do it this
way since an xu_updade_f1_ue_data() function would be almost the same as
the add function (only deleting existing data, whereas the original
add() was asserting in that case).
Modify tests to test for this behavior.
This fixes a concurrency bug. For instance, during reestablishment, the
CU needs to update the DU UE ID under which the UE is identified in the
DU. Previously, the CU would remove, then add the DU UE ID info.
At the same time, the PDCP thread might look up the information. This
can lead to asserts. Use the above addmod functionality to do the
remove-add under a mutex.

Fix calculation of RSSI in pucch_rx.c
Fix two issues with RSSI calculation in PUCCH:
- RSSI was calculated using partial sum instead of average of squared samples.
- There was a missing parentheses pair which causes the RSSI value to underflow.
The proper way to calculate power in dBFS is
let signal_energy = average of squared samples of received signal over resource elements, antennas and symbols under measurement
then:
rssi[dBFS] = -10log10(max_sample^2 / signal_energy),
or (to avoid division):
rssi[dBFS] = -(10log10(max_sample^2) - 10log10(signal_energy))
CI: Increase number of test trials for timing tests
- Increasing a number of test trials aims to reduce variations and
improve reliability of the nr_ulsim and nr_dlsim test results.
- Disable CPU sleep states on the machine when running physims.
- Minor adjustment of timing threshold in 60 MHz phytest.
Delay compensation for PUCCH2
- Implementation of delay compensation for PUCCH2, which minimizes for
exampe logs "reported RSRP index XXX invalid"
- Adding a test to the CI to perform the delay compensation in PUCCH2
- Refactor code to use c16_t data type in PUCCH decoder
Remove spinlock from threadpool task return
The idea to use atomic aligned to cache line for counting finished jobs
is reused, but instead of polling a semaphore was added.
remove calls to clear SIMD registers, that was a historical issue
This works because gcc/clang replaces the MMX calls by SSE2 automatically.
There are some mm_empty() calls in bad places (places where we don't use
_m64) and it is lacking in places where we still use _m64. Given that
MMX calls are converted to SSE2, there is no problem, and we will remove
remaining _m64 variables.

* this function is used by both CU-CP and CU-UP
* it behaves differently depending on the type of E1 instance:
CU-CP: inform RRC of E1 connection loss with CU-UP
CU-UP: trigger a new SCTP association request by sending an ITTI to the CU-UP task
* after receiving the E1AP register request, the CU-UP will send a new association request to
SCTP until new E1 connection is achieved by sending a TIMER_HAS_EXPIRED message to the CU-UP
task. The function e1apHandleTimer() is basically triggering a new E1 association request
until new E1 connection is achieved
* print SCTP association state in e1ap.c whenever needed

* add function to check whether cu-up is connected

* set return value of trigger_bearer_setup to bool and handle the

i.e. send failed list of items when no CU-UP is associated to the CU-CP
note: it considers all PDU Sessions as failed to setup in the considered failure scenarios
* e.g. send a list of failed PDU session resources in the response message to reject

* the Initial Context Setup has a Failure message, but for the considered failure scenario
when no CU-UP is available the current design is just sending a list of failed to setup
items in the Response message

RSSI threshold for PUSCH & PUCCH power control
To prevent ADC railing or "clipping" when the received power is too
large, introduce RSSI threshold parameters for PUSCH and PUCCH, which
are now configured in units of 0.1 dB. Here is how you can configure and
use these thresholds:
1. Configuration:
- Set the pusch_RSSI_Threshold and pucch_RSSI_Threshold parameters in
your configuration file (e.g., gnb.conf) (MACRLC section).
- These parameters define the maximum acceptable RSSI values for
PUSCH and PUCCH, respectively. The unit is either dBm or dBFS,
depending on the RSSI reporting configuration.
2. Usage:
- The nr_limit_tpc function will automatically adjust the Transmit
Power Control (TPC) commands based on the configured RSSI
thresholds.
- If the RSSI exceeds the threshold, the TPC command will be limited
to prevent further increase in power, thereby avoiding ADC
clipping.
Introduce ITTI queue in RRC-to-MAC direction
resolve ue rcc to mac race conditions by a itti queue, but it doesn't
resolve the problem of exact slot we should apply the new cell
configurtion
fhi_72: allow to provide dpdk_iova_mode to xran
- Introduce a gNB configuration option that enables users to select the
desired IOVA mode for DPDK ("PA" or "VA") with dpdk_iova_mode
parameters in fhi_72 configuration section. If not set, the default
remains PA mode to ensure backward compatibility with existing
configurations. Detailed information about IOVA modes, including their
advantages and disadvantages, can be found in the DPDK documentation:
Memory in DPDK Part 2: Deep Dive into IOVA
- Using IOVA VA mode allows DPDK to run without requiring SYS_ADMIN
capability for the docker container.
- Switch to IOVA VA mode in the FHI7.2 pipeline and reduce the required
capabilities for the docker container.
Move UL_INFO structure allocation local to a rx slot processing
UL_INFO is allocated a gNB, so require mutex and obscur information
passing function to function. Instead, make a local UL_INFO per slot,
removing the mutex and making the code easier to understand.
Use UL_INFO on the stack, to simplify the code. move in the same struct
the associated rach, pdu, crc, srs arrays that where pointed from
directly in gNB structure Keep in nfapi the existing logic that make
malloc for theses rach, pdu, crc, srs array lists
Pass only relevant fields, where appropriate.
