For me, I use bpf_output_trace_data() to output information like PMU count value. Perf is the only receiver, so global collector is perfect. Could you please describe your usecase in more detail?
there is a special receiver in user space that only wants the data from the bpf program that it loaded. It shouldn't conflict with any other processes. Like when it's running, I still should be able to use perf for other performance analysis. There is no way to share single bpf:bpf_output_data event, since these user processes are completely independent. -- 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/
