- **Log Buffer Manager** (`ble_log_lbm.c`): Log buffer management supporting multiple locking mechanisms

- **Multi-source Log Collection**: Supports multiple log sources including Link Layer, Host, HCI, UART redirection, etc.
- **High Concurrency Processing**: Uses atomic and spin lock mechanisms for multi-task concurrent writing
- **Real-time Transmission**: Asynchronous transmission mechanism based on FreeRTOS tasks
- **Real-time Transmission**: Asynchronous transmission through ESP Timer task dispatch
- **Data Integrity**: Checksum mechanism ensures data integrity (always enabled)
- **Multi-buffer Transport**: Each LBM manages multiple transport buffers (default 4) for improved throughput over the legacy ping-pong design
- **Cross-pool Buffer Fallback**: LBM acquire attempts all atomic LBMs before falling back to spinlock LBMs, improving buffer availability under contention

**Note**:
- All pending logs will be lost after calling this function
- Peripheral interface will be cleaned up first to avoid DMA transmission issues during memory release
- This function may run concurrently with BLE Log write APIs. New writes are
rejected after shutdown begins, and deinit waits for in-progress writers
before releasing their buffers.

# BLE Log Runtime Test App
## Overview
On-target regression and latency suite for the BLE Log runtime dispatch layer:
the esp_timer deferred batch dispatch and the submission ownership gate.
The app runs on real hardware (any BLE-capable chip, currently tested on
ESP32-C6 and ESP32-C5). The transport is replaced by a software model
(`CONFIG_BLE_LOG_PRPH_TEST=y`) that mimics DMA ownership transfer and stamps
the hand-over time, so dispatch latency is measured without a real link.
## Test Cases
- `runtime dispatch latency`: 32 single submissions and 32 four-transport
bursts. Verifies exact delivery order/count and prints enqueue-to-receipt
min/avg/p50/p95/max latency (`BLE_LOG_RT_PERF` lines) for the single,
first-in-burst, and last-in-burst paths.
- `runtime` regressions: shared ESP Timer task fairness, periodic timestamp
delivery without light-sleep wakeups, ISR-only submission delivery,
consumer-independent receipt timing, extra-marker detection, exact 1 ms
first-submission defer scheduling, full task-pool snapshot dispatch, deinit
racing submissions (SMP-pinned writer, failure-safe recovery), bounded
inflight-peak statistics, and monotonic millisecond waits at both supported
tick rates.
The first-deadline and full task-pool regressions require dispatch exclusion
while enqueueing, so they run on single-core builds only (they are ignored on
SMP targets). The deinit-race regression pins its writer to the other core on
SMP.
## Build, Flash, Run
```bash
cd components/bt/common/ble_log/test_apps/ble_log_rt_test
idf.py set-target <chip>
idf.py -p <PORT> build flash monitor
```
Timeout regressions are verified at both supported tick rates: the default
build uses the production 100 Hz; the 1000 Hz variant has a dedicated overlay:
```bash
idf.py -B build_1000 -p <PORT> -D SDKCONFIG=sdkconfig.1000 \
-D SDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.defaults.tick_1000" \
set-target <chip> build flash monitor
```
The app boots into the Unity menu; enter a test number to run it.
## Parsing Results
The latency lines can be rendered into tables/CSV with the parser shipped in
the perf test app:
```bash
idf.py -p <PORT> monitor | tee capture.log
python3 ../ble_log_perf_test/tools/parse_perf_log.py capture.log
python3 ../ble_log_perf_test/tools/parse_perf_log.py capture.log --csv out.csv
```
