Yeah, so no. This breaks what groups are. Group events _must_ be co-scheduled. You cannot guarantee you can schedule events from another PMU. Also, I cannot see how this can possibly work, you cannot put these things on the same event_context. Also, how does this work wrt cpumasks, regular events are per cpu, uncore events are per node. There is so much broken stuff here without explanation its not funny. Please explain how this does not completely wreck everything? -- 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/
