We have considered the option of using Oprofile's mechanisms for VTune, but Oprofile and VTune do different things in different ways. For example, both tools capture performance data, but Oprofile was designed with aggregation in mind whereas VTune was designed to collect all the data and then post-process it. We are open to putting the VTune driver into the kernel source tree. However, is consolidation of the performance tools a requirement for getting the four additional event notifications into the kernel? -juan - 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/
