perf ftrace: Introduce new 'ftrace' tool The 'perf ftrace' command is a simple wrapper of kernel's ftrace functionality. It only supports single thread tracing currently and just reads trace_pipe in text and then write it to stdout. Committer notes: Testing it: # perf ftrace -f function_graph usleep 123456 <SNIP> 2) | SyS_nanosleep() { 2) | _copy_from_user() { <SNIP> 2) 0.900 us | } 2) 1.354 us | } 2) | hrtimer_nanosleep() { 2) 0.062 us | __hrtimer_init(); 2) | do_nanosleep() { 2) | hrtimer_start_range_ns() { <SNIP> 2) 5.025 us | } 2) | schedule() { 2) 0.125 us | rcu_note_context_switch(); 2) 0.057 us | _raw_spin_lock(); 2) | deactivate_task() { 2) 0.369 us | update_rq_clock.part.77(); 2) | dequeue_task_fair() { <SNIP> 2) + 22.453 us | } 2) + 23.736 us | } 2) | pick_next_task_fair() { <SNIP> 2) + 47.167 us | } 2) | pick_next_task_idle() { <SNIP> 2) 4.462 us | } ------------------------------------------ 2) usleep-20387 => <idle>-0 ------------------------------------------ 2) 0.806 us | switch_mm_irqs_off(); ------------------------------------------ 2) <idle>-0 => usleep-20387 ------------------------------------------ 2) 0.151 us | finish_task_switch(); 2) @ 123597.2 us | } 2) 0.037 us | _cond_resched(); 2) | hrtimer_try_to_cancel() { 2) 0.064 us | hrtimer_active(); 2) 0.353 us | } 2) @ 123605.3 us | } 2) @ 123606.2 us | } 2) @ 123608.3 us | } /* SyS_nanosleep */ 2) | __do_page_fault() { <SNIP> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Tested-by: Masami Hiramatsu <mhiramat@kernel.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jeremy Eder <jeder@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com>, Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/n/tip-r1hgmsj4dxny8arn3o9mw512@git.kernel.org [ Various foward port fixes, add man page ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
