  This is the second version of metric value validation tests.

We made the following changes from v1 to v2:
 - Add python setting check [Ian]
 - Skip non-Intel architectures [Ian]
 - Rename allowlist to skiplist [Ian]

v1: https://lore.kernel.org/lkml/20230606202421.2628401-1-weilin.wang@intel.com/

Weilin Wang (3):
  perf test: Add metric value validation test
  perf test: Add skip list for metrics known would fail
  perf test: Rerun failed metrics with longer workload

Thanks Weilin,

when I try the test on my Tigerlake laptop I encounter an error:

```
$ sudo perf test 105 -vv

Could you take a look?
