Subject: [PATCH] perf stat report: Process event update events
Adding processing of event update events, so perf stat report can store
additional info for events - unit,scale,name.
Committer note:
Before:
# perf stat record -e power/energy-cores/ -a
^C
Performance counter stats for 'system wide':
77.41 Joules power/energy-cores/
1.597176695 seconds time elapsed
# perf stat report
Performance counter stats for '/home/acme/bin/perf stat record -e power/energy-cores/ -a':
332,488,114,176 power/energy-cores/
1.597176695 seconds time elapsed
#
After, using the same perf.data file generated in the "Before" case
above:
# perf stat report
Performance counter stats for '/home/acme/bin/perf stat record -e power/energy-cores/ -a':
77.41 Joules power/energy-cores/
1.597176695 seconds time elapsed
