168 # All tracer options should select GENERIC_TRACER. For those options that are
169 # enabled by all tracers (context switch and event tracer) they select TRACING.
170 # This allows those options to appear when no other tracer is selected. But the
244 sequence is then dynamically patched into a tracer call when
271 using function graph tracer. It can be helpful to locate functions
282 using function graph tracer. It can be helpful to locate code line that
292 the function tracer and function graph tracer will support printing
294 enabled via the trace option func-args (for the function tracer) and
295 funcgraph-args (for the function graph tracer)
350 tracer will ignore all the tracing functions. Sometimes it is useful
353 by the function tracer. Note, this will likely add noise to function
394 This special tracer records the maximum stack footprint of the
397 This tracer works by hooking into every function call that the
400 then it will not have any overhead while the stack tracer
403 To enable the stack tracer on bootup, pass in 'stacktrace'
406 The stack tracer can also be enabled or disabled via the
472 This tracer tracks the latency of the highest priority task
480 This tracer, when enabled will create one or more kernel threads,
485 time, this tracer will detect it. This is useful for testing
502 When the tracer is not running, it has no affect on the system,
504 periodically non responsive. Do not run this tracer on a
507 To enable this tracer, echo in "hwlat" into the current_tracer
512 bool "OS Noise tracer"
523 The osnoise tracer leverages the hwlat_detector by running a similar
525 the sources of osnoise during its execution. The osnoise tracer takes
534 interference. At the end of the period, the osnoise tracer prints
538 In addition to the tracer, a set of tracepoints were added to
543 To enable this tracer, echo in "osnoise" into the current_tracer
547 bool "Timerlat tracer"
551 The timerlat tracer aims to help the preemptive kernel developers
554 The tracer creates a per-cpu kernel thread with real-time priority.
555 The tracer thread sets a periodic timer to wakeup itself, and goes
561 The tracer prints two lines at every activation. The first is the
568 The tracer is build on top of osnoise tracer, and the osnoise:
592 This tracer hooks to various trace points in the kernel,
594 want to trace. It also includes the sched_switch tracer plugin.
602 Basic tracer to catch the syscall entry and exit events.
681 This tracer profiles all likely and unlikely macros
693 This tracer profiles all branch conditions. Every if ()
1119 a series of tests are made to verify that the tracer is
1226 tracer is running on, specify cpu_affinity=cpu_num at the end of the
