Recently the shadow stat metrics broke due to repeated aggregation and a quick fix was applied: https://lore.kernel.org/lkml/20230209064447.83733-1-irogers@google.com/ (local) This is the longer fix but one that comes with some extras. To avoid fixing issues for hard coded metrics, the topdown, SMI cost and transaction flags are moved into json metrics. A side effect of this is that TopdownL1 metrics will now be displayed when supported, if no "perf stat" events are specified. Another fix included here is for event grouping as raised in: https://lore.kernel.org/lkml/CA+icZUU_ew7pzWJJZLbj1xsU6MQTPrj8tkFfDhNdTDRQfGUBMQ@mail.gmail.com/ (local) Metrics are now tagged with NMI and SMT flags, meaning that the events shouldn't be grouped if the NMI watchdog is enabled or SMT is enabled. Given the two issues, the metrics are re-generated and the patches also include the latest Intel vendor events. The changes to the metric generation code can be seen in: https://github.com/intel/perfmon/pull/56 Hard coded metrics support thresholds, the patches add this ability to json metrics so that the hard coded metrics can be removed. Migrate remaining hard coded metrics to looking up counters from the evlist/aggregation count. Finally, get rid of the saved_value logic and thereby look to fix the aggregation issues. Some related fix ups and code clean ups are included in the changes, in particular to aid with the code's readability and to keep topdown documentation in sync.
