But we still need to handle PERF_RECORD_HEADER_EVENT_TYPE event for the sake of old perf data files created in pipe mode like: $ perf.3.4 record -o - foo >perf.data $ perf.312 report -i - < perf.data Reported-by: Stephane Eranian <eranian@xxxxxxxxxx> Signed-off-by: Jiri Olsa <jolsa@xxxxxxxxxx> Cc: Corey Ashford <cjashfor@xxxxxxxxxxxxxxxxxx> Cc: David Ahern <dsahern@xxxxxxxxx> Cc: Frederic Weisbecker <fweisbec@xxxxxxxxx> Cc: Ingo Molnar <mingo@xxxxxxx> Cc: Namhyung Kim <namhyung@xxxxxxxxxx> Cc: Paul Mackerras <paulus@xxxxxxxxx> Cc: Peter Zijlstra <a.p.zijlstra@xxxxxxxxx> Link: http://lkml.kernel.org/r/1391524668-12546-1-git-send-email-jolsa@xxxxxxxxxx Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> --- tools/perf/util/session.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/tools/perf/util/session.c b/tools/perf/util/session.c index 0b39a48..5da6ce7 100644 --- a/tools/perf/util/session.c +++ b/tools/perf/util/session.c @@ -1008,6 +1008,12 @@ static int perf_session__process_user_event(struct perf_session *session, union if (err == 0) perf_session__set_id_hdr_size(session); return err; + case PERF_RECORD_HEADER_EVENT_TYPE: + /* + * Depreceated, but we need to handle it for sake + * of old data files create in pipe mode. + */ + return 0; case PERF_RECORD_HEADER_TRACING_DATA: /* setup for reading amidst mmap */ lseek(fd, file_offset, SEEK_SET); -- To unsubscribe from this list: send the line "unsubscribe linux-tip-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
