perf test: Hybrid improvements for metric value validation test
On my alderlake I currently see for the "perf metrics value validation" test: ``` Total Test Count: 142 Passed Test Count: 139 [ Metric Relationship Error: The collected value of metric ['tma_fetch_latency', 'tma_fetch_bandwidth', 'tma_frontend_bound'] is [31.137028] in workload(s): ['perf bench futex hash -r 2 -s'] but expected value range is [tma_frontend_bound, tma_frontend_bound] Relationship rule description: 'Sum of the level 2 children should equal level 1 parent', Metric Relationship Error: The collected value of metric ['tma_memory_bound', 'tma_core_bound', 'tma_backend_bound'] is [6.564442] in workload(s): ['perf bench futex hash -r 2 -s'] but expected value range is [tma_backend_bound, tma_backend_bound] Relationship rule description: 'Sum of the level 2 children should equal level 1 parent', Metric Relationship Error: The collected value of metric ['tma_light_operations', 'tma_heavy_operations', 'tma_retiring'] is [57.806179] in workload(s): ['perf bench futex hash -r 2 -s'] but expected value range is [tma_retiring, tma_retiring] Relationship rule description: 'Sum of the level 2 children should equal level 1 parent'] Metric validation return with erros. Please check metrics reported with errors. ``` I suspect it is due to two metrics for different CPU types being enabled. Add a -cputype option to avoid this. The test still fails with: ``` Total Test Count: 115 Passed Test Count: 114 [ Wrong Metric Value Error: The collected value of metric ['tma_l2_hit_latency'] is [117.947088] in workload(s): ['perf bench futex hash -r 2 -s'] but expected value range is [0, 100]] Metric validation return with errors. Please check metrics reported with errors. ``` which is a reproducible genuine error and likely requires a metric fix.
