In stats mode PERF_RECORD_EVENT_UPDATE isn't being handled meaning the
evsels aren't named when handling pipe mode output.
Before:
$ perf record -e inst_retired.any -a -o - sleep 0.1|perf report --stats -i -
...
Aggregated stats:
TOTAL events: 23358
COMM events: 2608 (11.2%)
EXIT events: 1 ( 0.0%)
FORK events: 2607 (11.2%)
SAMPLE events: 174 ( 0.7%)
MMAP2 events: 17936 (76.8%)
ATTR events: 2 ( 0.0%)
FINISHED_ROUND events: 2 ( 0.0%)
ID_INDEX events: 1 ( 0.0%)
THREAD_MAP events: 1 ( 0.0%)
CPU_MAP events: 1 ( 0.0%)
EVENT_UPDATE events: 3 ( 0.0%)
TIME_CONV events: 1 ( 0.0%)
FEATURE events: 20 ( 0.1%)
FINISHED_INIT events: 1 ( 0.0%)
raw 0xc0 stats:
SAMPLE events: 174
After:
$ perf record -e inst_retired.any -a -o - sleep 0.1|perf report --stats -i -
...
Aggregated stats:
TOTAL events: 23742
COMM events: 2620 (11.0%)
EXIT events: 2 ( 0.0%)
FORK events: 2619 (11.0%)
SAMPLE events: 165 ( 0.7%)
MMAP2 events: 18304 (77.1%)
ATTR events: 2 ( 0.0%)
FINISHED_ROUND events: 2 ( 0.0%)
ID_INDEX events: 1 ( 0.0%)
THREAD_MAP events: 1 ( 0.0%)
CPU_MAP events: 1 ( 0.0%)
EVENT_UPDATE events: 3 ( 0.0%)
TIME_CONV events: 1 ( 0.0%)
FEATURE events: 20 ( 0.1%)
FINISHED_INIT events: 1 ( 0.0%)
inst_retired.any stats:
SAMPLE events: 165
This makes the pipe output match the regular output.
