It works fine with dummy, but user space code looked odd when it perf_event_open-s dummy events and starts reading them. So I thought either to add alias: PERF_COUNT_SW_BPF_OUTPUT = PERF_COUNT_SW_DUMMY or add new number like I did above. New number is cheap and I saw that dummy used for probing, so went with new number to disambiguate. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
