perf list: Display metric expressions for --details option
Display metric expression itself when --details is specified.
Current list with no details:
# perf list metrics
...
TopDownL1:
IPC
[Instructions Per Cycle (per logical thread)]
SLOTS
[Total issue-pipeline slots]
...
Detailed output with metric formula:
# perf list --details metrics
...
TopDownL1:
IPC
[Instructions Per Cycle (per logical thread)]
[inst_retired.any / cpu_clk_unhalted.thread]
SLOTS
[Total issue-pipeline slots]
[4*(( cpu_clk_unhalted.thread_any / 2 ) if #smt_on else cycles)]
