trace-cmd-stack - read, enable or disable Ftrace Linux kernel stack tracing.
trace-cmd stack
The trace-cmd(1) stack enables the Ftrace stack tracer within the kernel. The stack tracer enables the function tracer and at each function call within the kernel, the stack is checked. When a new maximum usage stack is discovered, it is recorded.
When no option is used, the current stack is displayed.
To enable the stack tracer, use the option --start, and to disable the stack tracer, use the option --stop. The output will be the maximum stack found since the start was enabled.
Use --reset to reset the stack counter to zero.
