Currently libtraceevent emits warning on unsupported event formats. However it'd be better to see them only -v option is given. To do that, it needs to override the warning() function which is used in the libtracevent. Thus add set_warning_routine() same as set_die_routine() and check the verbose flag in our warning routine. Before: # perf test 5 5: parse events tests : Warning: [kvmmmu:kvm_mmu_get_page] bad op token { Warning: [kvmmmu:kvm_mmu_sync_page] bad op token { Warning: [kvmmmu:kvm_mmu_unsync_page] bad op token { Warning: [kvmmmu:kvm_mmu_prepare_zap_page] bad op token { Warning: [kvmmmu:fast_page_fault] function is_writable_pte not defined ...
