+Trace Library
+=============
+
+DPDK provides a tracing library that gives the ability to add tracepoints
+in application to get runtime trace/debug information for control and fast
+APIs with minimum impact on fast path performance. Typical trace overhead is
+~20 cycles and instrumentation overhead is 1 cycle.
+
+Library mainly caters below mentioned use cases:
+
+- The DPDK provider will not have access to the DPDK customer applications.
+  Inbuilt tracer support will us enable to debug/analyze the slow path and
+  fast path DPDK API usage.
+
+- Provides a low overhead fast path multi-core PMD driver's debugging/analysis
+  infrastructure to fix the functional and performance issue(s).
+
+- Post trace analysis tools can provide various status across the system such
+  as cpu_idle() using the timestamp added in the trace.
+
+Below sections will provide detailed information about:
+
+ - Trace a user application
+ - View and analyze the recorded events
+
+Trace a user application
+------------------------
+
+This section steps you through a simple example to trace an application.
+A trace can be achieved using below mentioned steps:
+
+Define and register a tracepoint
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The application can define and register tracepoints either existing C file or
+create a new file (say xyz_app_trace_point.c). Also, all the tracepoints must be
+resolved before rte_eal_init i.e. tracepoints must be registered as constructor
+using RTE_INIT interface.
+
+Following are the MACRO definition exposed by the trace Library to define and
+register a tracepoint.
+
+.. code-block:: c
+
+ #define RTE_TRACE_POINT_DEFINE(tp)\
+        uint64_t __attribute__((section("__rte_trace_point"))) __##tp
+
+ #define RTE_TRACE_POINT_REGISTER(trace, name, level)\
+       __rte_trace_point_register(&__##trace, RTE_STR(name), RTE_LOG_ ## level,\
+                                  (void (*)(void)) trace)
+
+Example tracepoint definition and registration
+
+.. code-block:: c
+
+ RTE_TRACE_POINT_DEFINE(rte_trace_lib_eal_generic_str); /* Definition */
+
+ RTE_INIT(eal_trace_init)
+ {
+     /* Registration */
+     RTE_TRACE_POINT_REGISTER(rte_trace_lib_eal_generic_str,
+                              lib.eal.generic.str, INFO);
+ }
+
+For more details refer trace API documentation.
+Defined tracepoint must be exported into corresponding .map file.
+
+.. Note::
+
+    A tracepoint is defined like __##tp i.e. __rte_trace_lib_eal_generic_str
+    for above example. Same must be updated into corresponding .map file.
+
+Define trace function to write events
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+After a successful tracepoint registration, the application must define a
+trace function which solves three purposes:
+
+ - Calculates the size of the event.
+ - Generate CTF metadata field string for the event.
+ - Emit the event to trace memory.
+
+A tracepoint can be classified as either a data path or a slow path tracepoint.
+So based on that, the application must define tracepoint function using one of
+the mentioned MACRO
+
+.. code-block:: c
+
+ /* Define tracepoint function for slow path */
+ #define RTE_TRACE_POINT(tp, args, ...)\
+        __RTE_TRACE_POINT(generic, tp, args, __VA_ARGS__)
+
+ /* Define tracepoint function for data path */
+ #define RTE_TRACE_POINT_DP(tp, args, ...)\
+        __RTE_TRACE_POINT(dp, tp, args, __VA_ARGS__)
+
+RTE_TRACE_POINT_DP is compiled out by default and can be enabled using
+CONFIG_RTE_ENABLE_TRACE_DP configuration parameter. Also application can use
+``rte_trace_is_dp_enabled`` to get current status of RTE_TRACE_POINT_DP.
+For more details, refer DPDK Trace API documentation.
+
+Example tracepoint function definition
+
+.. code-block:: c
+
+ /* Slow path tracepoint */
+ RTE_TRACE_POINT(
+        rte_trace_lib_eal_generic_str,
+        RTE_TRACE_POINT_ARGS(const char *str),
+        rte_trace_ctf_string(str);
+ )
+
+ /* Data path tracepoint */
+ RTE_TRACE_POINT_DP(
+        rte_trace_lib_eal_generic_str,
+        RTE_TRACE_POINT_ARGS(const char *str),
+        rte_trace_ctf_string(str);
+ )
+
+Emit events to trace memory
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+After trace function definition is ready to emit tracepoints.
+To emit the event application needs to invoke tracepoint function, as defined
+in the above steps, at the desired location.
+
+Below examples emit tracepoints in ``rte_eth_dev_configure`` to print a test
+string:
+
+.. code-block:: c
+
+ int
+ rte_eth_dev_configure(uint16_t port_id, uint16_t nb_rx_q, uint16_t nb_tx_q,
+        const struct rte_eth_conf *dev_conf)
+ {
+        struct rte_eth_dev *dev;
+        struct rte_eth_dev_info dev_info;
+        struct rte_eth_conf orig_conf;
+        int diag;
+        int ret;
+
+        RTE_ETH_VALID_PORTID_OR_ERR_RET(port_id, -EINVAL);
+
+        dev = &rte_eth_devices[port_id];
+
+        RTE_FUNC_PTR_OR_ERR_RET(*dev->dev_ops->dev_configure, -ENOTSUP);
+
+        ...
+
+        rte_trace_lib_eal_generic_str("tp_test_string");
+        return ret;
+ }
+
+Generate CTF formatted metadata
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+As of now emitted events just specify the debug information written by the
+application but to view/analyze these events must be formatted into Common Trace
+Format(CTF) so that any CTF compliant trace analysis tool can view those traces.
+
+Trace library exposes below API to write events to CTF formatted metadata file.
+
+.. code-block:: c
+
+ int rte_trace_save(void);
+
+Currently library invokes this API implicitly during tear down and metadata file
+is generated at either ``/root/dpdk-traces/rte-yyyy-mm-dd-[AP]M-hh-mm-ss/`` or
+at location if user has passed during command line(``say /tmp``) then
+``/tmp/rte-yyyy-mm-dd-[AP]M-hh-mm-ss/``
+
+For more information, refer :doc:`../linux_gsg/linux_eal_parameters` for trace.
+
+View and analyze the recorded events
+------------------------------------
+Once ``Trace a user application`` is completed, the user can view/inspect the
+recorded events.
+
+There are many tools you can use to read DPDK traces:
+
+ - ``babeltrace`` is a command-line utility that converts trace formats; it
+   supports the format that DPDK trace library produces, CTF, as well as a
+   basic text output that can be grep ed. The babeltrace command is part of the
+   opensource ``Babeltrace`` project.
+
+ - ``Trace Compass`` is a graphical user interface for viewing and analyzing any
+   type of logs or traces, including DPDK traces.
+
+.. Note::
+
+   This section assumes that the trace library saved the traces, it recorded
+   during the previous tutorials, to their specified location.
+
+
+Use the babeltrace command-line tool
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The simplest way to list all the recorded events of a trace is to pass its path
+to babeltrace with no options::
+
+    babeltrace </path-to-trace-events/rte-yyyy-mm-dd-[AP]M-hh-mm-ss/>
+
+``babeltrace`` finds all traces recursively within the given path and prints all
+their events, merging them in chronological order.
+
+You can pipe the output of the babeltrace into a tool like grep(1) for further
+filtering. Below example grep the events for ``ethdev`` only::
+
+    babeltrace /tmp/my-dpdk-trace | grep ethdev
+
+You can pipe the output of babeltrace into a tool like wc(1) to count the
+recorded events. Below example count the number of ``ethdev`` events::
+
+    babeltrace /tmp/my-dpdk-trace | grep ethdev | wc --lines
+
+Use the tracecompass GUI tool
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+``Tracecompass`` is another tool to view/analyze the DPDK traces which gives
+a graphical view of events. Like ``babeltrace``, tracecompass also provides
+an interface to search for a particular event. To use ``tracecompass``, following are
+the minimum required steps:
+
+ - Install ``tracecompass`` to the localhost. Variants are available for Linux,
+   Windows, and OS-X.
+ - Launch ``tracecompass`` which will open a graphical window with trace
+   management interfaces.
+ - Open a trace using ``File->Open Trace`` option and select metadata file
+   which is to be viewed/analyzed.
+
+For more details, refer `Trace Compass <https://www.eclipse.org/tracecompass/>`_
+
+Core Concepts
+-------------
+As DPDK trace library is designed to generate traces that uses Common Trace
+Format(CTF). CTF specification consist of following units to create a trace.
+
+ - ``Stream`` Sequence of packets.
+ - ``Packet`` Header and one or more events.
+ - ``Event`` Header and payload.
+
+For detailed information, refer `Common Trace Format <https://diamon.org/ctf/>`_
+
+Channel and trace memory
+~~~~~~~~~~~~~~~~~~~~~~~~
+A channel is an object which is responsible for holding the trace memory.
+The trace library creates the trace memory per thread to enable the lock-less
+scheme to emit the event. When a DPDK tracer emits an event, it will be recorded
+to the trace buffers that associated with that thread.
+
+Event record mode
+~~~~~~~~~~~~~~~~~
+Event record mode is an attribute of trace buffers. Trace library exposes two
+modes:
+
+ - ``Overwrite`` This mode enables trace buffers to wrap around when trace buffer memory is full.
+ - ``Discard`` This mode enables trace buffers to discard when trace buffer memory is full.
+
+This mode can be enabled/disabled either using eal command line parameters or
+DPDK trace library API to configure the mode.
+Refer :doc:`../linux_gsg/linux_eal_parameters` and trace API documentation more
+details.
+
+Metadata
+~~~~~~~~
+Metadata defines the layout of event records so that trace analysis tool can
+read the streams and show into the relevant format.
+For more details, refer `Common Trace Format <https://diamon.org/ctf/>`_.
