Since commit 8989f5f07605 ("perf stat: Update POWER9 metrics to utilize
other metrics"), power9 has reused metrics.
And I am finding that subtest 10.3 caused problems when I tried to introduce
metric reuse on arm64, so I was just asking you to check.
Now I am a bit confused...
I now understand your original request!:-)
The above test was run on a POWER8 system.
I do see failures on a POWER9 system:
--
$ ./perf test 10
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Skip
(some metrics failed)
10.4: Parsing of PMU event table metrics with fake PMUs : Ok
$ ./perf test --verbose 10 2>&1 | grep -i '^Parse event failed' | wc -l
112
ok, thanks for confirming.
I'm looking at fixing it, and the solution doesn't look simple :(
