This is handled without issue by the parse events code, but the pmu alias code gets a bit confused, as it warns about assigning "event=0x5" over "config=0x5" in perf_pmu_assign_str() when merging aliases: ./perf stat -v -e act_cmd ... alias act_cmd differs in field 'value' ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some Intel platforms, such as Alderlake, which is a hybrid platform and it consists of atom cpu and core cpu. Each cpu has dedicated event list. Part of events are available on core cpu, part of events are available on atom cpu. The kernel exports new cpu pmus: cpu_core and cpu_atom. The event in json is added with a new field "Unit" to indicate which pmu the event is available on. For example, one event in cache.json, { "BriefDescription": "Counts the number of load ops retired that", "CollectPEBSRecord": "2", "Counter": "0,1,2,3", "EventCode": "0xd2", "EventName": "MEM_LOAD_UOPS_RETIRED_MISC.MMIO", "PEBScounters": "0,1,2,3", "SampleAfterValue": "1000003", "UMask": "0x80", "Unit": "cpu_atom" }, The unit "cpu_atom" indicates this event is only available on "cpu_atom". In generated pmu-events.c, we can see: { .name = "mem_load_uops_retired_misc.mmio", .event = "period=1000003,umask=0x80,event=0xd2", .desc = "Counts the number of load ops retired that. Unit: cpu_atom ", .topic = "cache", .pmu = "cpu_atom", }, But if without this patch, the "uncore_" prefix is added before "cpu_atom", such as: .pmu = "uncore_cpu_atom" That would be a wrong pmu.

Add them. Preserve the events for Zen3 if they are measurable and non-zero as taken from Zen2 directory even if the PPR of Zen3 [1] omits them.

| | | | | | | | | | | | | | | | | | | | | | | The values of event codes and umasks are inconsistent with letter cases. Enforce a unique style and default everything to lower case as this helps in tracking changes of automatically generated event tables.
