tools script: Add --call-trace and --call-ret-trace
Add short cut options to print PT call trace and call-ret-trace, for calls and call and returns. Roughly corresponds to ftrace function tracer and function graph tracer. Just makes these common use cases nicer to use. % perf record -a -e intel_pt// sleep 1 % perf script --call-trace perf 900 [000] 194167.205652203: ([kernel.kallsyms]) perf_pmu_enable perf 900 [000] 194167.205652203: ([kernel.kallsyms]) __x86_indirect_thunk_rax perf 900 [000] 194167.205652203: ([kernel.kallsyms]) event_filter_match perf 900 [000] 194167.205652203: ([kernel.kallsyms]) group_sched_in perf 900 [000] 194167.205652203: ([kernel.kallsyms]) __x86_indirect_thunk_rax perf 900 [000] 194167.205652203: ([kernel.kallsyms]) event_sched_in.isra.107 perf 900 [000] 194167.205652203: ([kernel.kallsyms]) perf_event_set_state.part.71 perf 900 [000] 194167.205652203: ([kernel.kallsyms]) perf_event_update_time perf 900 [000] 194167.205652203: ([kernel.kallsyms]) perf_pmu_disable perf 900 [000] 194167.205652203: ([kernel.kallsyms]) perf_log_itrace_start perf 900 [000] 194167.205652203: ([kernel.kallsyms]) __x86_indirect_thunk_rax perf 900 [000] 194167.205652203: ([kernel.kallsyms]) perf_event_update_userpage % perf script --call-ret-trace perf 900 [000] 194167.205652203: tr strt ([unknown]) pt_config perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) pt_config perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) pt_event_add perf 900 [000] 194167.205652203: call ([kernel.kallsyms]) perf_pmu_enable perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) perf_pmu_nop_void perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) event_sched_in.isra.107 perf 900 [000] 194167.205652203: call ([kernel.kallsyms]) __x86_indirect_thunk_rax perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) perf_pmu_nop_int perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) group_sched_in perf 900 [000] 194167.205652203: call ([kernel.kallsyms]) event_filter_match perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) event_filter_match perf 900 [000] 194167.205652203: call ([kernel.kallsyms]) group_sched_in perf 900 [000] 194167.205652203: call ([kernel.kallsyms]) __x86_indirect_thunk_rax perf 900 [000] 194167.205652203: return ([kernel.kallsyms]) perf_pmu_nop_txn perf 900 [000] 194167.205652203: call ([kernel.kallsyms]) event_sched_in.isra.107 perf 900 [000] 194167.205652203: call ([kernel.kallsyms]) perf_event_set_state.part.71 Signed-off-by: Andi Kleen <ak@linux.intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Tested-by: Leo Yan <leo.yan@linaro.org> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Kim Phillips <kim.phillips@arm.com> Link: http://lkml.kernel.org/r/20180920180540.14039-4-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
