I don't know what do you mean to generalize this to arbitary events. I think a generalization will be obvious, when we will have a few examples. Currently we can modify events by a simple way. What would I want to have? It's a way to create a new event type and events in "perf inject". > > -Andi > > -- > a...@linux.intel.com -- Speaking for myself only -- 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/
