Ah, it should be the original V2 missed the below change.

@@ -100,5 +101,25 @@ void arch_perf_synthesize_sample_weight(const
struct perf_sample *data,
 	if (type & PERF_SAMPLE_WEIGHT_STRUCT) {
 		*array &= 0xffffffff;
 		*array |= ((u64)data->ins_lat << 32);
+		*array |= ((u64)data->retire_lat << 48);
 	}
 }

Could you please remove the V2 and re-apply the V3?

$ sudo ./perf test -v "x86 sample parsing"
 74: x86 Sample parsing                                              :

test child forked, pid 3316797
test child finished with 0
---- end ----
x86 Sample parsing: Ok


Thanks,
Kan
