abgaber c834a694ae doc: update data recording documentation for v1.1 architecture 2026-04-24 10:31:38 +02:00
abgaber 2f23dd2444 data-recording v1.1: Major rewrite of the synchronized real-time data recording system. 
Application (v1.1):
- Generic N-node architecture replacing hardcoded gNB/UE structure
- Node-based JSON config with per-node shared memory paths
- Thread pool with barrier sync for multi-node recording
- Frame/slot-based message grouping in read_and_store_tracer_messages()
- Robust cleanup via atexit and signal handlers
- Remove v1.0 legacy application

Shared Memory Interface (new):
- System V shared memory attach/detach/remove with ftok-based keys
- Structured binary read/write for tracer control messages
- Frame/slot-aware data reading with configurable timeout

Config Interface:
- JSON-based config with node definitions (id, type, shared_mem_config)
- Per-node tracer message parsing and index resolution

SigMF Interface:
- Timestamp refactor: Unix epoch sec/nsec with nanosecond precision
- Wireless parameter mapping via YAML-driven parameter map
- System components metadata (TX/channel/RX) in SigMF annotations

Sync Service:
- Generic multi-node sync replacing 2-node sync
- Frame-wrap-aware comparison (1024-frame wrap)

Wireless Parameters Mapper (new):
- YAML-driven OAI-to-SigMF parameter mapping
- 5G NR metadata derivation (DMRS, modulation, link direction)

abgaber 46a4097f6a T-Tracer: update shared memory sizing for 5 messages/slot 
Set NUM_MESSAGES_PER_SLOT=5, 100 slots buffer depth (~234 MiB).
Add separate project IDs and ftok paths for gNB and UE.

abgaber b242eb3093 T-Tracer gNB and UE: massive enhancements 
- refactor timestamp handling
- Replace string-based SENDING_TIME with integer SEC/NSEC fields.
- Designed the shared memory protocol with a 4-state machine (STATE_WAIT=0, STATE_CONFIG=1, STATE_RECORD=2, STATE_STOP=3) for command/control between the recording app and the T-Tracer service
- Implemented two shared memory segments: one for reading commands (addr_rd) and one for writing captured data (addr_wr)
- Created event_trace_msg_ul_data struct mapping all 27 UL metadata fields (frame, slot, datetime, MCS, DMRS parameters, etc.) by name from the T-Tracer database
- Implemented setup_trace_msg_ul_data() using the G() macro to map field names to indices at startup
- Wrote the main event loop using poll() to avoid busy-waiting, with get_event() to receive T-Tracer events from the softmodem socket

abgaber 5558f98154 PHY/gNB: replace inline T() calls with T_messages_creator wrappers 
Use log_ul_fd_dmrs, log_ul_fd_pusch_iq, log_ul_fd_chan_est_dmrs_pos,
log_ul_fd_chan_est_dmrs_interpl, log_ul_payload_rx_bits.

abgaber 80ad56af63 T-Tracer: add T_messages_creator.c to T library build 2026-04-24 10:31:38 +02:00
abgaber b75ddf0e85 T-Tracer: add T_messages_creator wrapper functions for UL PHY trace logging 
Introduce T_messages_creator.h/.c with 7 modular wrapper functions
(log_ul_fd_dmrs, log_ul_fd_pusch_iq, log_ul_fd_chan_est_dmrs_pos,
log_ul_fd_chan_est_dmrs_interpl, log_ul_payload_rx_bits,
log_ul_payload_tx_bits, log_ul_scrambled_tx_bits) that encapsulate
T() macro calls with structured PHY metadata fields.
Replaces scattered inline T() calls across PHY source files.
