+libperf tutorial
+================
+
+Compile and install libperf from kernel sources
+===============================================
+.. code-block:: bash
+
+ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+ cd linux/tools/perf/lib
+ make
+ sudo make install prefix=/usr
+
+Libperf object
+==============
+The libperf library provides several high level objects:
+
+struct perf_cpu_map
+ Provides a cpu list abstraction.
+
+struct perf_thread_map
+ Provides a thread list abstraction.
+
+struct perf_evsel
+ Provides an abstraction for single a perf event.
+
+struct perf_evlist
+ Gathers several struct perf_evsel object and performs functions on all of them.
+
+The exported API binds these objects together,
+for full reference see the libperf.7 man page.
+
+Examples
+========
+Examples aim to explain libperf functionality on simple use cases.
+They are based in on a checked out linux kernel git tree:
+
+.. code-block:: bash
+
+ $ cd tools/perf/lib/Documentation/tutorial/
+ $ ls -d ex-*
+ ex-1-compile ex-2-evsel-stat ex-3-evlist-stat
+
+ex-1-compile example
+====================
+This example shows the basic usage of *struct perf_cpu_map*,
+how to create it and display its cpus:
+
+.. code-block:: bash
+
+ $ cd ex-1-compile/
+ $ make
+ gcc -o test test.c -lperf
+ $ ./test
+ 0 1 2 3 4 5 6 7
+
+
+The full code listing is here:
+
+.. code-block:: c
+
+ 1 #include <perf/cpumap.h>
+ 2
+ 3 int main(int argc, char **Argv)
+ 4 {
+ 5 struct perf_cpu_map *cpus;
+ 6 int cpu, tmp;
+ 7
+ 8 cpus = perf_cpu_map__new(NULL);
+ 9
+ 10 perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
+ 11 fprintf(stdout, "%d ", cpu);
+ 12
+ 13 fprintf(stdout, "\n");
+ 14
+ 15 perf_cpu_map__put(cpus);
+ 16 return 0;
+ 17 }
+
+
+First you need to include the proper header to have *struct perf_cpumap*
+declaration and functions:
+
+.. code-block:: c
+
+ 1 #include <perf/cpumap.h>
+
+
+The *struct perf_cpumap* object is created by *perf_cpu_map__new* call.
+The *NULL* argument asks it to populate the object with the current online CPUs list:
+
+.. code-block:: c
+
+ 8 cpus = perf_cpu_map__new(NULL);
+
+This is paired with a *perf_cpu_map__put*, that drops its reference at the end, possibly deleting it.
+
+.. code-block:: c
+
+ 15 perf_cpu_map__put(cpus);
+
+The iteration through the *struct perf_cpumap* CPUs is done using the *perf_cpu_map__for_each_cpu*
+macro which requires 3 arguments:
+
+- cpu - the cpu numer
+- tmp - iteration helper variable
+- cpus - the *struct perf_cpumap* object
+
+.. code-block:: c
+
+ 10 perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
+ 11 fprintf(stdout, "%d ", cpu);
