commit 082651a7812b0dba20aaea970ebd529b78f6202d

perf parse-events: Add new "metric-id" term
[ Upstream commit 2b62b3a611715d3ca612e3225cf436277ed9648b ]
Add a new "metric-id" term to events so that metric parsing can set an
ID that can be reliably looked up.
Metric parsing currently will turn a metric like "instructions/cycles"
into a parse events string of "{instructions,cycles}:W".
However, parse-events may change "instructions" into "instructions:u" if
perf_event_paranoid=2.
When this happens expr__resolve_id currently fails as stat-shadow adds
the ID "instructions:u" to match with the counter value and the metric
tries to look up the ID just "instructions".
A later patch will use the new term.
An example of the current problem:
$ echo -1 > /proc/sys/kernel/perf_event_paranoid
$ perf stat -M IPC /bin/true
Performance counter stats for '/bin/true':
1,217,161 inst_retired.any # 0.97 IPC
1,250,389 cpu_clk_unhalted.thread
0.002064773 seconds time elapsed
0.002378000 seconds user
0.000000000 seconds sys
$ echo 2 > /proc/sys/kernel/perf_event_paranoid
$ perf stat -M IPC /bin/true
Performance counter stats for '/bin/true':
150,298 inst_retired.any:u # nan IPC
187,095 cpu_clk_unhalted.thread:u
0.002042731 seconds time elapsed
0.000000000 seconds user
0.002377000 seconds sys
Note: nan IPC is printed as an effect of "perf metric: Use NAN for
missing event IDs." but earlier versions of perf just fail with a parse
error and display no value.
