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