perf list: Support printing MetricExpr with --debug
Output the metric expr in perf list when --debug is specified, so that
the user can check the formula.
Before:
% perf list
...
unc_m_power_channel_ppd
[Cycles where DRAM ranks are in power down (CKE) mode. Derived from unc_m_power_channel_ppd. Unit:
uncore_imc]
uncore_imc_2/event=0x85/
After:
% perf list --debug
...
unc_m_power_channel_ppd
[Cycles where DRAM ranks are in power down (CKE) mode. Derived from unc_m_power_channel_ppd. Unit:
uncore_imc]
Perf: uncore_imc_2/event=0x85/ MetricExpr: (unc_m_power_channel_ppd / unc_m_clockticks) * 100.
