172 # All tracer options should select GENERIC_TRACER. For those options that are
173 # enabled by all tracers (context switch and event tracer) they select TRACING.
174 # This allows those options to appear when no other tracer is selected. But the
248 sequence is then dynamically patched into a tracer call when
275 using function graph tracer. It can be helpful to locate functions
286 using function graph tracer. It can be helpful to locate code line that
296 the function tracer and function graph tracer will support printing
298 enabled via the trace option func-args (for the function tracer) and
299 funcgraph-args (for the function graph tracer)
354 tracer will ignore all the tracing functions. Sometimes it is useful
357 by the function tracer. Note, this will likely add noise to function
398 This special tracer records the maximum stack footprint of the
401 This tracer works by hooking into every function call that the
404 then it will not have any overhead while the stack tracer
407 To enable the stack tracer on bootup, pass in 'stacktrace'
410 The stack tracer can also be enabled or disabled via the
473 This tracer tracks the latency of the highest priority task
481 This tracer, when enabled will create one or more kernel threads,
486 time, this tracer will detect it. This is useful for testing
503 When the tracer is not running, it has no affect on the system,
505 periodically non responsive. Do not run this tracer on a
508 To enable this tracer, echo in "hwlat" into the current_tracer
513 bool "OS Noise tracer"
524 The osnoise tracer leverages the hwlat_detector by running a similar
526 the sources of osnoise during its execution. The osnoise tracer takes
535 interference. At the end of the period, the osnoise tracer prints
539 In addition to the tracer, a set of tracepoints were added to
544 To enable this tracer, echo in "osnoise" into the current_tracer
548 bool "Timerlat tracer"
552 The timerlat tracer aims to help the preemptive kernel developers
555 The tracer creates a per-cpu kernel thread with real-time priority.
556 The tracer thread sets a periodic timer to wakeup itself, and goes
562 The tracer prints two lines at every activation. The first is the
569 The tracer is build on top of osnoise tracer, and the osnoise:
593 This tracer hooks to various trace points in the kernel,
595 want to trace. It also includes the sched_switch tracer plugin.
603 Basic tracer to catch the syscall entry and exit events.
684 This tracer profiles all likely and unlikely macros
696 This tracer profiles all branch conditions. Every if ()
1122 a series of tests are made to verify that the tracer is
1229 tracer is running on, specify cpu_affinity=cpu_num at the end of the
