2020-07-03perf record: Fix duplicated sideband events with Intel PT system wide tracingAdrian Hunter1-0/+1
Commit 0a892c1c9472 ("perf record: Add dummy event during system wide synthesis") reveals an issue with Intel PT system wide tracing. Specifically that Intel PT already adds a dummy tracking event, and it is not the first event. Adding another dummy tracking event causes duplicated sideband events. Fix by checking for an existing dummy tracking event first. Example showing duplicated switch events: Before: # perf record -a -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.895 MB perf.data ] # perf script --no-itrace --show-switch-events | head swapper 0 [007] 6390.516222: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 swapper 0 [007] 6390.516222: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 rcu_sched 11 [007] 6390.516223: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 rcu_sched 11 [007] 6390.516224: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 rcu_sched 11 [007] 6390.516227: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 rcu_sched 11 [007] 6390.516227: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 swapper 0 [007] 6390.516228: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 11/11 swapper 0 [007] 6390.516228: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 11/11 swapper 0 [002] 6390.516415: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 5556/5559 swapper 0 [002] 6390.516416: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 5556/5559 After: # perf record -a -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.868 MB perf.data ] # perf script --no-itrace --show-switch-events | head swapper 0 [005] 6450.567013: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 7179/7181 perf 7181 [005] 6450.567014: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 perf 7181 [005] 6450.567028: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 swapper 0 [005] 6450.567029: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 7179/7181 swapper 0 [005] 6450.571699: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 rcu_sched 11 [005] 6450.571700: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 rcu_sched 11 [005] 6450.571702: PERF_RECORD_SWITCH_CPU_WIDE OUT next pid/tid: 0/0 swapper 0 [005] 6450.571703: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 11/11 swapper 0 [005] 6450.579703: PERF_RECORD_SWITCH_CPU_WIDE OUT preempt next pid/tid: 11/11 rcu_sched 11 [005] 6450.579704: PERF_RECORD_SWITCH_CPU_WIDE IN prev pid/tid: 0/0 Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20200629091955.17090-3-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

As the "perf_" prefix should be restricted to functions and types in tools/lib/perf/, aka libperf, this way we reduce a bit the confusion for types only in libperf or the ones in the more contained tools/perf/ project.

2020-05-05perf evlist: Allow reusing the side band thread for more purposesArnaldo Carvalho de Melo1-0/+1
I.e. so far we had just one event in that side band thread, a dummy one with attr.bpf_event set, so that 'perf record' can go ahead and ask the kernel for further information about BPF programs being loaded. Allow for more than one event to be there, so that we can use it as well for the upcoming --switch-output-event feature.

2020-05-05perf bpf: Decouple creating the evlist from adding the SB eventArnaldo Carvalho de Melo1-1/+1
Renaming bpf_event__add_sb_event() to evlist__add_sb_event() and requiring that the evlist be allocated beforehand. This will allow using the same side band thread and evlist to be used for multiple purposes in addition to react to PERF_RECORD_BPF_EVENT soon after they are generated.

2019-11-29perf stat: Use affinity for opening eventsAndi Kleen1-1/+2
Restructure the event opening in perf stat to cycle through the events by CPU after setting affinity to that CPU. This eliminates IPI overhead in the perf API. We have to loop through the CPU in the outter builtin-stat code instead of leaving that to low level functions. It has to change the weak group fallback strategy slightly. Since we cannot easily undo the opens for other CPUs move the weak group retry to a separate loop. Before with a large test case with 94 CPUs: % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 42.75 4.050910 67 60046 110 perf_event_open After: 26.86 0.944396 16 58069 110 perf_event_open (the number changes slightly because the weak group retries work differently and the test case relies on weak groups) Committer notes: Added one of the hunks in a patch provided by Andi after I noticed that the "event times" 'perf test' entry was segfaulting.

2019-11-22perf record: Add a function to test for kernel support for AUX area samplingAdrian Hunter1-0/+1
Architectures are expected to know if AUX area sampling is supported by the hardware. Add a function perf_can_aux_sample() which will determine whether the kernel supports it. Committer notes: I reported that this message was taking place on a kernel without the required bits: # perf record --aux-sample -e '{intel_pt//u,branch-misses:u}' Error: The sys_perf_event_open() syscall returned with 7 (Argument list too long) for event (branch-misses:u). /bin/dmesg | grep -i perf may provide additional information. Adrian sent a patch addressing it, with this explanation: ---- perf_can_aux_sample_size() always returned true because it did not pass the attribute size to sys_perf_event_open, nor correctly check the return value and errno. ---- After applying it I get, later in the series, when --aux-sample is added: # perf record --aux-sample -e '{intel_pt//u,branch-misses:u}' AUX area sampling is not supported by kernel Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20191115124225.5247-4-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2019-10-09perf evlist: Introduce append_tp_filter_pid() and append_tp_filter_pids()Arnaldo Carvalho de Melo1-0/+3
We'll need this to support 'perf trace e tracepoint --filter=expr', as the command line tracepoint filter is attache to the preceding evsel, just like in 'perf record' and when we go to set pid filters, which we do at the minimum to filter 'perf trace' own syscalls, we need to append, not set the tp filter.

2019-10-09perf evlist: Introduce append_tp_filter() methodArnaldo Carvalho de Melo1-0/+2
Will be used by 'perf trace' to support 'perf trace --filter', we need to append to any pre-existing filter. When parse_filter() gets invoked to process --filter, it'll set the filter to that specified on the command line, later on, when we filter out 'perf trace' own pid to avoid an event feedback loop, we need to preserve the command line filter put in place by parse_filter().
