It generates, mirrors, and checks cyclic Ethernet frames to\n-measure round-trip latency, jitter and frame loss for middlewares like PROFINET and OPC/UA PubSub,\n-and to benchmark per-frame security (AES-256). It is a platform/driver/stack evaluation tool, **not**\n-a TSN conformance tester. All TSN mechanisms use mainline-Linux-only utilities.\n-\n-Two binaries are built:\n-\n-- **`reference`** — generates traffic and checks consistency + round-trip latency.\n-- **`mirror`** — reflects traffic generated by `reference` back to it.\n-\n-A test run needs two machines connected back-to-back or via a TSN network, synchronized with PTP.\n-The `mirror` must always be started **before** `reference` (internal sequence counting).\n-\n-## Build\n-\n-```bash\n-mkdir build && cd build\n-cmake -DCMAKE_BUILD_TYPE=Release -DWITH_MQTT=TRUE ..\n-make -j$(nproc)\n-sudo make install\n-```\n-\n-`CMAKE_BUILD_TYPE` matters — it sets the compiler flags (`Release`, `Debug`, `RelWithDebInfo`).\n-\n-Optional CMake flags:\n-\n-- `-DWITH_MQTT=ON` — MQTT metric export (needs `libmosquitto-dev`).\n-- `-DRX_TIMESTAMP=ON` — Rx latency display (libbpf >= 1.2).\n-- `-DTX_TIMESTAMP=ON` — Tx HW timestamping (libxdp >= 1.5.2 + kernel `XDP_TXMD_FLAGS_TIMESTAMP`).\n-- `-DWITH_ASAN=ON` — AddressSanitizer.\n-- `-DWITH_TESTS=ON` — build unit tests (needs `cmocka`).\n-\n-Build deps: `cmake`, `gcc`, `clang`, `llvm`, `pkg-config`, `libbpf-dev`, `libyaml-dev`, `libxdp-dev`,\n-`libssl-dev` (OpenSSL >= 3.0), optionally `libmosquitto-dev`, `libnl-3-dev` + `libnl-genl-3-dev`\n-(for the `napictl` helper, which also needs kernel v6.13+ headers).\n-\n-XDP eBPF programs (`src/xdp_kern_*.c`) are compiled separately by CMake with `clang -target bpf`.\n-`src/xdp_kern_tb.c` is compiled multiple times via `add_xdp_prog_tb()` in `CMakeLists.txt` with\n-different `-DEBPF_VID`/`-DEBPF_ETH_TYPE`/`-DEBPF_PRIORITY` defines, producing one `.o` per\n-VID/protocol (PROFINET, OPC/UA, AVTP). When changing XDP steering, edit both the source and the\n-`add_xdp_prog_tb()` invocations.\n-\n-## Unit tests\n-\n-```bash\n-cd build\n-cmake -DWITH_TESTS=ON .. && make -j$(nproc)\n-ctest --output-on-failure # run all\n-ctest -R ring_buffer_test # run a single test by name\n-```\n-\n-Tests use `cmocka` and live in `tests/unit/`. Each test compiles the unit under test directly\n-(e.g. `ring_buffer_test.c` + `src/ring_buffer.c`) — add new tests in `tests/unit/CMakeLists.txt`.\n-\n-## Running a test scenario\n-\n-Scenarios live in `tests//` as YAML configs (`reference.yaml`, `mirror.yaml`) plus shell\n-scripts (`flow.sh` configures the NIC qdiscs/filters, `ptp.sh` starts PTP, `ref.sh`/`mirror.sh`\n-wrappers). Typical flow on each of the two machines:\n-\n-```bash\n-cd tests/profinet\n-../../scripts/ptp.sh enp3s0 # 1. PTP sync (once); needs /etc/gPTP.cfg from linuxptp\n-./flow.sh enp3s0 # 2. traffic flow / qdisc config (once)\n-cp ../../build/xdp_kern_*.o . # XDP object files must sit next to the config\n-# host2 (mirror) first:\n-../../build/mirror -c mirror.yaml\n-# host1 (reference) second:\n-../../build/reference -c reference.yaml\n-```\n-\n-Results are written to `/var/log/{reference,mirror}_vid.log`. For real-time classes the max\n-round-trip time should stay below 2× the cycle time, with zero lost or damaged frames. See\n-`Documentation/test.rst` for the full catalogue of scenarios (multi-middleware, PTM, netload,\n-busypolling, working clock, etc.) and their hardware requirements.\n-\n-Validate a kernel config against the testbench's requirements with:\n-\n-```bash\n-scripts/check_kconfig.pl /path/to/.config\n-```\n-\n-Required options include `CONFIG_PTP_1588_CLOCK`, `CONFIG_XDP_SOCKETS`, `CONFIG_NET_SCH_TAPRIO`,\n-`CONFIG_NET_SCH_ETF`, `CONFIG_DEBUG_INFO_BTF`. A `PREEMPT_RT` kernel (recent LTS) is required.\n-\n-## Architecture\n-\n-The applications perform cyclic Ethernet communication split into **traffic classes** ranging from\n-real-time Layer 2 up to UDP. Receivers/transmitters use either traditional `AF_PACKET` (BPF filter\n-steering) or modern `AF_XDP` (eBPF/XDP steering) sockets, selected per class by config.\n-\n-- **`src/reference.c` / `src/mirror.c`** — entry points. Parse config, spawn threads per enabled\n- class, link them into the send chain, run until Ctrl-C.\n-- **`src/config.c/.h`** — YAML parsing into `struct app_config` + per-class\n- `struct traffic_class_config`. The config is the source of truth for which classes run, cycle\n- time, frame counts/sizes, VID/PCP, socket type, and security.\n-- **`src/thread.h`** — the central `struct thread_context`: socket fd, XDP socket, ring buffer,\n- Tx/Rx security contexts, traffic-class config, and `next` pointer to the following class. The\n- `enum pn_thread_type` (TSN_HIGH, TSN_LOW, RTC, RTA, DCP, LLDP, UDP_HIGH, UDP_LOW) defines class\n- ordering and priority.\n-- **`src/*_thread.c`** — one file per traffic class (`tsn`, `rtc`, `rta`, `dcp`, `lldp`, `udp`,\n- `layer2`). Each provides Rx, Tx, and (for generated classes) a Tx-generation thread.\n-- **`src/xdp.c` / `src/xdp_metadata.c`** — AF_XDP socket setup and the zero-copy send/receive path;\n- Rx/Tx metadata (timestamps, launch time).\n-- **`src/security.c`** — per-frame AES-256-GCM authentication/encryption via OpenSSL 3.x.\n-- **`src/packet.c` / `src/net.c` / `src/profinet.c`** — frame construction/parsing, low-level\n- socket helpers, PROFINET frame layout and frame-id handling.\n-- **`src/stat.c` / `src/hist.c`** — per-frame-type round-trip statistics and latency histograms.\n-- **`src/ring_buffer.c`** — lock-free-ish ring buffer carrying Rx frames to be mirrored.\n-- **`src/log.c` / `src/log_json.c` / `src/log_mqtt.c`** — text, JSON, and optional MQTT metric output.\n-- **`src/workload.c`** — dynamically loaded `.so` workload plugins simulating RT CPU load (see\n- `tests/workloads/`, e.g. `jacobi_2d`, `pointer_chasing`). `mirror` is linked with\n- `--export-dynamic` so plugins can resolve symbols.\n-- **`src/tx_time.c`** — ETF / Tx launch-time (Qbv end-station) support.\n-- **`src/napictl.c`** — standalone helper (built only with libnl3 + kernel v6.13+) for NAPI config.\n-\n-**Thread chaining is the key mechanism:** the traffic classes form a linked list via\n-`thread_context.next` (`link_pn_threads()`). When the first class finishes its Tx cycle it signals\n-the next via `pthread_cond_signal` on `data_cond_var`, so frames leave the wire in deterministic\n-strict-priority order within each cycle. `is_first`/`is_last` mark the chain ends.\n-\n-## Code style\n-\n-Linux kernel coding style. Run `clang-format` (config in `.clang-format`) on C files when unsure;\n-`.clang-tidy` is also present. Perl scripts in `scripts/` use the same style via `perltidy` (config\n-in `.perltidyrc`, since clang-format does not support Perl); run `perltidy -b .pl`. Use\n-**reverse xmas tree** (RCS) local-variable ordering — longest declarations first:\n-\n-```c\n-unsigned long long big_variable;\n-unsigned int medium;\n-int small;\n-```\n-\n-Commit messages follow the Linux kernel convention: imperative subject, body explaining _why_, and a\n-`Signed-off-by:` trailer.

Testbench documentation napictl file.\n-..\n-\n-.. _napictl:\n-\n-NAPI Configuration (napictl)\n-============================\n-\n-Introduction\n-------------\n-\n-``napictl`` is a small standalone helper that configures the NAPI parameters\n-``defer-hard-irqs`` and ``gro-flush-timeout`` for an individual queue of a network\n-interface. It is primarily used to enable kernel side busy polling for the queue that\n-carries the real time traffic, which reduces the jitter introduced by hardware and software\n-interrupts. See the :ref:`Busypolling` test for the corresponding use case.\n-\n-Background\n-----------\n-\n-The Linux kernel exposes two NAPI parameters relevant for busy polling:\n-\n-- ``defer-hard-irqs``: How often the NAPI processing is deferred, i.e. how many times the\n- kernel busy polls a queue before re-arming the hardware interrupt.\n-- ``gro-flush-timeout``: Timeout (in nanoseconds) after which the kernel takes over the NAPI\n- processing again. For cyclic real time traffic it has to be larger than the application\n- cycle time, otherwise the kernel falls back to interrupt driven processing within a cycle.\n-\n-Both parameters can be set globally for a whole interface via ``sysfs``::\n-\n- /sys/class/net//napi_defer_hard_irqs\n- /sys/class/net//gro_flush_timeout\n-\n-However, in a converged TSN setup only the queue(s) carrying the real time streams should be\n-busy polled, while the remaining queues stay interrupt driven to save CPU cycles. The ``sysfs``\n-interface cannot express this per-queue granularity. ``napictl`` therefore uses the netlink\n-``netdev`` generic netlink API to resolve the NAPI instance(s) backing a given queue and to set\n-both parameters only for that queue.\n-\n-Requirements\n-------------\n-\n-``napictl`` is only built when its build and runtime requirements are met:\n-\n-- ``libnl-3`` and ``libnl-genl-3`` development packages at build time.\n-- Linux kernel v6.13+ headers providing the ``netdev`` generic netlink commands\n- ``NETDEV_CMD_QUEUE_GET`` and ``NETDEV_CMD_NAPI_SET``.\n-- A network driver that supports per-queue NAPI configuration. This currently works for the\n- Intel ``igc`` (i225/i226) and ``igb`` drivers.\n-\n-If the requirements are not satisfied, ``cmake`` skips the target and prints::\n-\n- Building napictl configuration tool requires kernel v6.13+\n-\n-When the requirements are met, ``cmake`` prints ``Found libnl3: Building napictl configuration\n-tool`` and the binary is produced as ``build/napictl``. See :ref:`Build` for the package names\n-on Debian and RHEL based systems.\n-\n-Command Line Usage\n-------------------\n-\n-.. code:: bash\n-\n- host: ./napictl -h\n- usage: napictl [options]\n- options:\n- -i, --interface: Network interface to configure\n- -q, --queue: Queue of network interface to configure\n- -d, --defer-hard-irqs: Set defer-hard-irqs\n- -g, --gro-flush-timeout: Set gro-flush-timeout\n- -h, --help: Print this help text\n- -v, --verbose: Print verbose messages\n- -V, --version: Print version\n-\n-.. list-table:: Options\n- :widths: 30 70\n- :header-rows: 1\n-\n- * - Option\n- - Description\n-\n- * - ``-i``, ``--interface``\n- - Network interface to configure (mandatory).\n-\n- * - ``-q``, ``--queue``\n- - Queue index to configure. Defaults to ``0``.\n-\n- * - ``-d``, ``--defer-hard-irqs``\n- - Value for ``defer-hard-irqs``. Defaults to ``0``.\n-\n- * - ``-g``, ``--gro-flush-timeout``\n- - Value for ``gro-flush-timeout`` in nanoseconds.

Note:: ``napictl`` modifies network interface settings and therefore requires\n- ``CAP_NET_ADMIN`` (e.g. run it as ``root``).\n-\n-How It Works\n-------------\n-\n-For the requested queue ``napictl``:\n-\n-1. Resolves the interface index from the interface name.\n-2. Issues a ``NETDEV_CMD_QUEUE_GET`` dump and matches the queue index to obtain the NAPI ids of\n- its receive and transmit NAPI instances.\n-3. Applies ``defer-hard-irqs`` and ``gro-flush-timeout`` to both the Rx and Tx NAPI instances via\n- ``NETDEV_CMD_NAPI_SET``.\n-\n-Passing ``-v`` prints the resolved NAPI ids and the values that get applied, which is helpful for\n-debugging the queue to NAPI mapping.\n-\n-Examples\n---------\n-\n-Configure ``defer-hard-irqs`` and a ``gro-flush-timeout`` of 2 ms (2000000 ns) for queue 0 of\n-``enp3s0``:\n-\n-.. code:: bash\n-\n- napictl -i enp3s0 -q 0 -d 10 -g 2000000\n-\n-Reset the parameters for queue 0 back to their defaults (interrupt driven processing):\n-\n-.. code:: bash\n-\n- napictl -i enp3s0 -q 0 -d 0 -g 0\n-\n-The test scripts wrap ``napictl`` in the ``napi_defer_hard_irqs_queue()`` helper from\n-``tests/lib/common.sh``, which derives ``gro-flush-timeout`` from the cycle time and applies the\n-settings per queue:\n-\n-.. code:: bash\n-\n- # napi_defer_hard_irqs_queue($napictl, $interface, $cycle_time_ns, $queue)\n- napi_defer_hard_irqs_queue \"../../build/napictl\" \"enp3s0\" \"1000000\" 0\n-\n-See ``tests/busypolling_napiconf/`` and ``tests/er26/`` for complete examples.\ndiff --git a/Documentation/processing_latency.rst b/Documentation/processing_latency.rst\nindex 45c1e22..f4168c4 100644\n--- a/Documentation/processing_latency.rst\n+++ b/Documentation/processing_latency.rst\n@@ -162,7 +162,7 @@ The following table summarizes all dependencies:\n - Any version\n * - **libxdp**\n - Any version\n- - >= 1.5.2\n+ - >= 1.4.1\n * - **NIC Driver Feature**\n - bpf_xdp_metadata_rx_timestamp()\n - XDP_TXMD_FLAGS_TIMESTAMP\n@@ -202,15 +202,13 @@ per cycle):\n .. code-block:: text\n \n # Processing Latency Metrics\n- TsnHighProcFirstMin=982 [us]\n+ TsnHighProcFirstMin=999 [us]\n TsnHighProcFirstMax=1001 [us]\n- TsnHighProcFirstAvg=998.476523 [us]\n- TsnHighProcFirstOutliers=1\n+ TsnHighProcFirstAvg=999.198684 [us]\n \n- TsnHighProcBatchMin=983 [us]\n+ TsnHighProcBatchMin=1002 [us]\n TsnHighProcBatchMax=1003 [us]\n- TsnHighProcBatchAvg=1000.237762 [us]\n- TsnHighProcBatchOutliers=739\n+ TsnHighProcBatchAvg=1002.000087 [us]\n \n Additional Monitoring Points\n ^^^^^^^^^^^^^^^^^^^^^^^^^^^^\ndiff --git a/Documentation/qa.rst b/Documentation/qa.rst\nindex 6f13d6a..07c2501 100644\n--- a/Documentation/qa.rst\n+++ b/Documentation/qa.rst\n@@ -1,6 +1,6 @@\n ..

When executed, the CPU must follow pointer chains, causing cache misses and memory stalls.\n-The buffer and span sizes can be customized to target specific hierarchies in the cache subsystem,\n-or sized sufficiently large for main memory.\n-\n-Key Components\n-^^^^^^^^^^^^^^\n-\n-1. **Data Structure (ptr_node)**\n-\n- - 64-byte aligned union containing a pointer to the next node and a value\n-\n-2. **Setup Phase (ptr_chase_setup)**\n-\n- - Parses buffer size and span size from command line arguments\n- - Allocates memory and creates a randomized linked list\n- - Buffer size: Total memory allocated\n- - Span size: Used in conjunction with ``CACHE_LINE_SIZE`` to determine how many linked list nodes\n- are traversed\n-\n-3. **Linked List Generation (create_linked_list)**\n-\n- - Creates a pseudo-random chain of pointers within the specified span\n- - Uses a seeded random number generator for reproducible results\n- - Ensures each node is visited exactly once\n-\n-4. **Execution (run_ptr_chasing)**\n- - Follows the pointer chain using optimized assembly code\n- - Assembly loop continues until reaching a NULL pointer\n-\n-Assembly Implementation\n-^^^^^^^^^^^^^^^^^^^^^^^\n-\n-The core loop is implemented in assembly for precise control:\n-\n-.. code:: NASM\n-\n- __chasing_code_loop:\n- mov (%rax), %rax ; Load next pointer\n- test %rax, %rax ; Check if NULL\n- jne __chasing_code_loop ; Continue if not NULL\n- ret ; Return when done\n-\n-ptr_chase_setup parameters\n-^^^^^^^^^^^^^^^^^^^^^^^^^^\n-\n-The ``ptr_chase_setup`` function expects two arguments:\n-\n-- **Buffer Size**: Total memory allocated (in hexadecimal)\n-- **Span Size**: Used in conjunction with ``CACHE_LINE_SIZE`` to determine how many linked list\n- nodes are traversed. As span size approaches buffer size, it will take longer to create the\n- LinkedList. Recommended to keep buffer size slightly larger than span size.\n-\n-In the ``tests/busypolling_1ms_rtworkload`` example, the following values are used:\n-\n-- Buffer size: 0x4A4000 (~4.6MB total allocation)\n-- Span size: 0x129000 (~1.2MB used for linked list)\n-\n-Example RTC-Testbench configuration file for pointer chasing\n-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n-\n-See ``tests/busypolling_1ms_rtworkload/mirror.yaml``.\n-\n-Build Instructions\n-^^^^^^^^^^^^^^^^^^\n-\n-From the main project build directory:\n-\n-.. code:: bash\n-\n- make pointer_chasing # Build shared library\n+`Pointer Chasing `_\ndiff --git a/README.md b/README.md\nindex 441c7d7..8c74c21 100644\n--- a/README.md\n+++ b/README.md\n@@ -86,8 +86,10 @@ Linux RealTime Communication `Testbench` features include:\n \n The following list contains ideas for further development:\n \n+- Rework busy polling configuration\n - Add configurations for other hardware platforms (hybrid!) and NIC(s)\n - Add integration with `ClockManager`\n+- Package for Debian\n \n ## Documentation\n \n@@ -103,7 +105,7 @@ Supported by Siemens AG and Intel Corporation\n \n ## Copyright\n \n-Copyright (C) 2020-2026 Linutronix GmbH\n+Copyright (C) 2020-2025 Linutronix GmbH\n \n Copyright (C) 2024 Intel Corporation\n \ndiff --git a/REUSE.toml b/REUSE.toml\ndeleted file mode 100644\nindex 021a367..0000000\n--- a/REUSE.toml\n+++ /dev/null\n@@ -1,28 +0,0 @@\n-version = 1\n-SPDX-PackageName = \"RTC-Testbench\"\n-SPDX-PackageSupplier = \"Kurt Kanzenbach \"\n-SPDX-PackageDownloadLocation = \"https://www.github.com/Linutronix/RTC-Testbench\"\n-\n-[[annotations]]\n-path = [\".clang-format\", \".clang-tidy\", \".perltidyrc\", \".dir-locals.el\", \"CONTRIBUTING.md\", \"Documentation/Makefile\", \"Documentation/conf.py\"]\n-precedence = \"aggregate\"\n-SPDX-FileCopyrightText = \"2020-2024 Linutronix GmbH\"\n-SPDX-License-Identifier = \"BSD-2-Clause\"\n-\n-[[annotations]]\n-path = [\"Documentation/images/**.png\", \"Documentation/make.bat\", \"ISSUE_TEMPLATE.md\", \"README.md\", \"AGENTS.md\"]\n-precedence = \"aggregate\"\n-SPDX-FileCopyrightText = \"2020-2024 Linutronix GmbH\"\n-SPDX-License-Identifier = \"BSD-2-Clause\"\n-\n-[[annotations]]\n-path = [\".github/workflows/sphinx.yml\", \"devtools/conda-envs/docs_env.yaml\", \"requirements.txt\", \".github/labels.yml\", \".github/workflows/label.yml\"]\n-precedence = \"aggregate\"\n-SPDX-FileCopyrightText = \"2024 Pablo Iranzo Gómez \"\n-SPDX-License-Identifier = \"BSD-2-Clause\"\n-\n-[[annotations]]\n-path = \"docker/mqtt-composer/**\"\n-precedence = \"aggregate\"\n-SPDX-FileCopyrightText = \"2024 Intel Corporation\"\n-SPDX-License-Identifier = \"BSD-2-Clause\"\ndiff --git a/debian/changelog b/debian/changelog\nindex 7e90589..228cda2 100644\n--- a/debian/changelog\n+++ b/debian/changelog\n@@ -1,24 +1,3 @@\n-rtc-testbench (5.5-1) unstable; urgency=medium\n-\n- * New upstream release.\n- * d/copyright: refresh coverage for upstream 5.5.\n- * d/source/lintian-overrides: document upstream release signature\n- availability.\n- * d/rules:\n- - Move workload shared objects to the multiarch library directory.\n- - Remove the unit-test CMakeLists.txt for internal logic, not the RTC\n- benchmark tests.\n- - Install the shared ptp.sh helper required by the packaged NIC benchmark\n- test scripts.\n- * d/control:\n- - bump Standards-Version to 4.7.4.\n- - bump debhelper compat to 14.\n- - Add bc for shipped flow scripts.\n- - Add libnl-3-dev, libnl-genl-3-dev, and linux-libc-dev to\n- Build-Depends for the 5.5 NAPI tooling.\n-\n- -- Gavin Lai (賴建宇) Sat, 12 Sep 2026 23:07:01 +0800\n-\n rtc-testbench (5.4-1) unstable; urgency=medium\n \n * New upstream release.

When executed, the CPU must follow pointer chains, causing cache misses and memory stalls.\n+The buffer and span sizes can be customized to target specific hierarchies in the cache subsystem,\n+or sized sufficiently large for main memory.\n+\n+### Key Components\n+\n+1. **Data Structure (`ptr_node`)**\n+\n+ - 64-byte aligned union containing a pointer to the next node and a value\n+\n+2. **Setup Phase (`ptr_chase_setup`)**\n+\n+ - Parses buffer size and span size from command line arguments\n+ - Allocates memory and creates a randomized linked list\n+ - Buffer size: Total memory allocated\n+ - Span size: Used in conjunction with `CACHE_LINE_SIZE` to determine how many linked list nodes\n+ are traversed\n+\n+3. **Linked List Generation (`createLinkedList`)**\n+\n+ - Creates a pseudo-random chain of pointers within the specified span\n+ - Uses a seeded random number generator for reproducible results\n+ - Ensures each node is visited exactly once\n+\n+4. **Execution (`run_ptr_chasing`)**\n+ - Follows the pointer chain using optimized assembly code\n+ - Assembly loop continues until reaching a NULL pointer\n+\n+### Assembly Implementation\n+\n+The core loop is implemented in assembly for precise control:\n+\n+```assembly\n+__chasing_code_loop:\n+ mov (%rax), %rax ; Load next pointer\n+ test %rax, %rax ; Check if NULL\n+ jne __chasing_code_loop ; Continue if not NULL\n+ ret ; Return when done\n+```\n+\n+### ptr_chase_setup parameters\n+\n+The `ptr_chase_setup` function expects two arguments:\n+\n+- **Buffer Size**: Total memory allocated (in hexadecimal)\n+- **Span Size**: Used in conjunction with `CACHE_LINE_SIZE` to determine how many linked list\n+ nodes are traversed.
