[PATCH 3/4] perf annotate: Process tracing data in pipe mode

From: David Carrillo-Cisneros
Date: Tue Jul 18 2017 - 21:19:50 EST


perf annotate was missing the handler for tracing data records.

Prior to this patch we obtained "unhandled" records when piping
trace events to perf annotate (using -D option to show the
dump_printf messages in process_event_synth_tracing_data_stub):

$ perf record -o - -e block:bio_free sleep 2 | perf annotate -D --stdio
...
0x78 [0xc]: PERF_RECORD_TRACING_DATA: unhandled!
...
