+          Enable the kernel to trace every kernel function. This is done
+          by using a compiler feature to insert a small, 5-byte No-Operation
+          instruction to the beginning of every kernel function, which NOP
+          sequence is then dynamically patched into a tracer call when
+          tracing is enabled by the administrator. If it's runtime disabled
+          (the bootup default), then the overhead of the instructions is very
+          small and not measurable even in micro-benchmarks.

+        help
+          This option measures the time spent in irqs-off critical
+          sections, with microsecond accuracy.
+
+          The default measurement method is a maximum search, which is
+          disabled by default and can be runtime (re-)started
+          via:
+
+              echo 0 > /debugfs/tracing/tracing_max_latency
+
+          (Note that kernel size and overhead increases with this option
+          enabled. This option and the preempt-off timing option can be
+          used together or separately.)

+        depends on X86
+        select TRACING
+        help
+          This tracer provides the trace needed by the 'Sysprof' userspace
+          tool.
+
+config SCHED_TRACER
+        bool "Scheduling Latency Tracer"
+        depends on HAVE_FTRACE
+        select TRACING
+        select CONTEXT_SWITCH_TRACER
+        select TRACER_MAX_TRACE
+        help
+          This tracer tracks the latency of the highest priority task
+          to be scheduled in, starting from the point it has woken up.
+
+config CONTEXT_SWITCH_TRACER
+        bool "Trace process context switches"
+        depends on HAVE_FTRACE
+        select TRACING
+        select MARKERS
+        help
+          This tracer gets called from the context switch and records
+          all switching of tasks.
+
+config DYNAMIC_FTRACE
+        bool "enable/disable ftrace tracepoints dynamically"
+        depends on FTRACE
+        depends on HAVE_DYNAMIC_FTRACE
+        default y
+        help
+         This option will modify all the calls to ftrace dynamically
+         (will patch them out of the binary image and replaces them
+         with a No-Op instruction) as they are called. A table is
+         created to dynamically enable them again.
+
+         This way a CONFIG_FTRACE kernel is slightly larger, but otherwise
+         has native performance as long as no tracing is active.
+
+         The changes to the code are done by a kernel thread that
+         wakes up once a second and checks to see if any ftrace calls
+         were made. If so, it runs stop_machine (stops all CPUS)
+         and modifies the code to jump over the call to ftrace.

+        help
+          This option performs a series of startup tests on ftrace. On bootup
+          a series of tests are made to verify that the tracer is
+          functioning properly. It will do tests on all the configured
+          tracers of ftrace.
