The initial test will verify that the test tables in generated pmu-events.c
match against known, expected values.
For known events added in pmu-events/arch/test, we need to add an entry
in test_cpu_aliases_events[] or test_uncore_events[].
A sample run is as follows for x86:
john@linux-3c19:~/linux> tools/perf/perf test -vv 10
10: PMU event aliases :
--- start ---
test child forked, pid 5316
testing event table bp_l1_btb_correct: pass
testing event table bp_l2_btb_correct: pass
testing event table segment_reg_loads.any: pass
testing event table dispatch_blocked.any: pass
testing event table eist_trans: pass
testing event table uncore_hisi_ddrc.flux_wcmd: pass
testing event table unc_cbo_xsnp_response.miss_eviction: pass
test child finished with 0
---- end ----
PMU event aliases: Ok
