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>

perf kwork: New tool to trace time properties of kernel work (such as softirq, and workqueue) The 'perf kwork' tool is used to trace time properties of kernel work (such as irq, softirq, and workqueue), including runtime, latency, and timehist, using the infrastructure in the perf tools to allow tracing extra targets. This is the first commit to reuse the 'perf record' framework code to implement a simple record function, kwork is not supported currently. Test cases: # perf usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS] The most commonly used perf commands are: <SNIP> iostat Show I/O performance metrics kallsyms Searches running kernel for symbols kmem Tool to trace/measure kernel memory properties kvm Tool to trace/measure kvm guest os kwork Tool to trace/measure kernel work properties (latencies) list List all symbolic event types lock Analyze lock events mem Profile memory accesses record Run a command and record its profile into perf.data <SNIP> See 'perf help COMMAND' for more information on a specific command. # perf kwork Usage: perf kwork [<options>] {record} -D, --dump-raw-trace dump raw trace in ASCII -f, --force don't complain, do it -k, --kwork <kwork> list of kwork to profile -v, --verbose be more verbose (show symbol address, etc) # perf kwork record -- sleep 1 [ perf record: Woken up 0 times to write data ] [ perf record: Captured and wrote 1.787 MB perf.data ] Signed-off-by: Yang Jihong <yangjihong1@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Clarke <pc@us.ibm.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20220709015033.38326-2-yangjihong1@huawei.com [ Add {} for multiline if blocks ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
