Checking the count matches all the tracepoints available plus current standard tracepoint perf_event_attr check. This test exposes warnings from traceevent lib about not being able to parse some tracepoints' format data. Exposing these messages in the automated test suite will probably speed up the fix ;-) Signed-off-by: Jiri Olsa Cc: Corey Ashford Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1355749718-4355-4-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/tests/parse-events.c | 62 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 62 insertions(+) diff --git a/tools/perf/tests/parse-events.c b/tools/perf/tests/parse-events.c index 294ffdd..e7eb708 100644 --- a/tools/perf/tests/parse-events.c +++ b/tools/perf/tests/parse-events.c @@ -3,6 +3,7 @@ #include "evsel.h" #include "evlist.h" #include "sysfs.h" +#include "debugfs.h" #include "tests.h" #include @@ -782,6 +783,63 @@ static int test__group5(struct perf_evlist *evlist __maybe_unused) return 0; } +static int count_tracepoints(void) +{ + char events_path[PATH_MAX]; + struct dirent *events_ent; + DIR *events_dir; + int cnt = 0; + + scnprintf(events_path, PATH_MAX, "%s/tracing/events", + debugfs_find_mountpoint()); + + events_dir = opendir(events_path); + + TEST_ASSERT_VAL("Can't open events dir", events_dir); + + while ((events_ent = readdir(events_dir))) { + char sys_path[PATH_MAX]; + struct dirent *sys_ent; + DIR *sys_dir; + + if (!strcmp(events_ent->d_name, ".") + || !strcmp(events_ent->d_name, "..") + || !strcmp(events_ent->d_name, "enable") + || !strcmp(events_ent->d_name, "header_event") + || !strcmp(events_ent->d_name, "header_page")) + continue; + + scnprintf(sys_path, PATH_MAX, "%s/%s", + events_path, events_ent->d_name); + + sys_dir = opendir(sys_path); + TEST_ASSERT_VAL("Can't open sys dir", sys_dir); + + while ((sys_ent = readdir(sys_dir))) { + if (!strcmp(sys_ent->d_name, ".") + || !strcmp(sys_ent->d_name, "..") + || !strcmp(sys_ent->d_name, "enable") + || !strcmp(sys_ent->d_name, "filter")) + continue; + + cnt++; + } + + closedir(sys_dir); + } + + closedir(events_dir); + return cnt; +} + +static int test__all_tracepoints(struct perf_evlist *evlist) +{ + TEST_ASSERT_VAL("wrong events count", + count_tracepoints() == evlist->nr_entries); + + return test__checkevent_tracepoint_multi(evlist); +} + struct test__event_st { const char *name; __u32 type; @@ -921,6 +979,10 @@ static struct test__event_st test__events[] = { .name = "{cycles,instructions}:G,{cycles:G,instructions:G},cycles", .check = test__group5, }, + [33] = { + .name = "*:*", + .check = test__all_tracepoints, + }, }; static struct test__event_st test__events_pmu[] = {
