+    Perf is a Linux profiling with performance counters.
+
+    Performance counters are CPU hardware registers that count hardware events
+    such as instructions executed, cache-misses suffered, or branches
+    mispredicted. They form a basis for profiling applications to trace dynamic
+    control flow and identify hotspots.
+
+    pref accepts options and events. If no option is given the default '-a' is
+    used. For events, the default events are migrations and cs. They both can
+    be specified in the config file.
+
+    Events must be provided as a list that contains them and they will look like
+    this ::
+
+        perf_events = ['migrations', 'cs']
+
+    Events can be obtained by typing the following in the command line on the
+    device ::
+
+        perf list
+
+    Whereas options, they can be provided as a single string as following ::
+
+        perf_options = '-a -i'
+
+    Options can be obtained by running the following in the command line ::
