doc: Sphinxify the tracepoint docbook
Convert the tracepoint docbook template to RST and add it to the core-api manual. No changes to the actual text beyond the mechanical formatting conversion. Cc: Jason Baron <jbaron@redhat.com> Cc: William Cohen <wcohen@redhat.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

Introduction
|
||||||
|
============
|
||||||
|
|
||||||
|
Tracepoints are static probe points that are located in strategic points
|
||||||
|
throughout the kernel. 'Probes' register/unregister with tracepoints via
|
||||||
|
a callback mechanism. The 'probes' are strictly typed functions that are
|
||||||
|
passed a unique set of parameters defined by each tracepoint.
|
||||||
|
|
||||||
|
From this simple callback mechanism, 'probes' can be used to profile,
|
||||||
|
debug, and understand kernel behavior. There are a number of tools that
|
||||||
|
provide a framework for using 'probes'. These tools include Systemtap,
|
||||||
|
ftrace, and LTTng.
|
||||||
|
|
||||||
|
Tracepoints are defined in a number of header files via various macros.
|
||||||
|
Thus, the purpose of this document is to provide a clear accounting of
|
||||||
|
the available tracepoints. The intention is to understand not only what
|
||||||
|
tracepoints are available but also to understand where future
|
||||||
|
tracepoints might be added.
|
||||||
|
|
||||||
|
The API presented has functions of the form:
|
||||||
|
``trace_tracepointname(function parameters)``. These are the tracepoints
|
||||||
|
callbacks that are found throughout the code. Registering and
|
||||||
|
unregistering probes with these callback sites is covered in the
|
||||||
|
``Documentation/trace/*`` directory.
