I'd say keep it in --filter, that noticing it is a bpf object would dtrt: perf record --filter bpf_thing.o usleep 1
agree. make sense. The only thing is that such bpf program defines both event and filter. Existing --filter applies to --event, whereas this bpf_thing.o does both and likely kprob-ing multiple events underneath. I guess '--filter' still fits. Just need to document it clearly. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
