Or > a starter on a starter. Sure, multiple ways to express ranges probably is ok, with more complex ones for more complex cases, like the way you did, that first defines an evlist that is the set of starters/stoppers and then evsel->evidx to add starters/stoppers to later events. But starter on a starter? Couldn't grok, could you provide an example? But I could think of this as a way to express filters: $ perf record -e instructions@irq:irq:irq_handler_entry(irq=eth0)..irq:irq_handler_exit(\1) \ -e instructions \ netperf looks quite natural for someone used to git and sed, i.e. developers :) - Arnaldo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
