23 'perf ftrace latency' calculates execution latency of a given function
26 'perf ftrace profile' show a execution profile for each function including
66 specified: function_graph or function.
87 Select function tracer and set function filter on the given
88 function (or a glob pattern). Multiple functions can be given
89 by using this option more than once. The function argument also
95 Select function tracer and do not trace functions given by the
103 - call-graph - Display kernel stack trace for function tracer.
104 - irq-info - Display irq context info for function tracer.
109 function (or a glob pattern). This is useful to trace for
110 functions executed from the given function. This can be used more
117 given function (or a glob pattern). Like -G option, this is useful
118 for the function_graph tracer only and disables tracing for function
119 executed from the given function. This can be used more than once to
126 - args - Show function arguments.
127 - retval - Show function return value.
128 - retval-hex - Show function return value in hexadecimal format.
129 - retaddr - Show function return address.
134 - depth=<n> - Set max depth for function graph tracer to follow.
135 - tail - Print function name at the end.
143 Set the function name to get the histogram. Unlike perf ftrace trace,
144 it only allows single function to calculate the histogram.
154 Use BPF to measure function latency instead of using the ftrace (it
178 Set function filter on the given function (or a glob pattern).
180 The function argument also can be a glob pattern. It will be passed
191 Set graph filter on the given function (or a glob pattern). This is
192 useful to trace for functions executed from the given function. This
198 Set graph notrace filter on the given function (or a glob pattern).
200 disables tracing for function executed from the given function. This
220 - depth=<n> - Set max depth for function graph tracer to follow.
