[lttng-dev] Can't receive a lot of functions that i registerd as trace-points

[Lin ArcX]

Hello,

I have a simple udp server/client and I want to trace these functions:

    Event rules:
      netif_rx_ni_entry (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      netif_rx_entry (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      napi_gro_receive_entry (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      softirq_raise (loglevel: TRACE_EMERG (0)) (type: tracepoint) [enabled]
      irq_handler_entry (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      napi_poll (loglevel: TRACE_EMERG (0)) (type: tracepoint) [enabled]
      softirq_entry (loglevel: TRACE_EMERG (0)) (type: tracepoint) [enabled]
      e1000_xmit_frame (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      ndo_start_xmit (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      net_dev_start_xmit (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      dev_queue_xmit (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      net_dev_queue (loglevel: TRACE_EMERG (0)) (type: tracepoint) [enabled]
      netif_receive_skb_list_entry (loglevel: TRACE_EMERG (0)) (type:
tracepoint) [enabled]
      netif_receive_skb (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]
      inet_sock_set_state (loglevel: TRACE_EMERG (0)) (type: tracepoint)
[enabled]

I start tracing, and when it is finished, I will open my trace directory
into TraceCompass, But I can see just some traces from these functions:

- irq_handler_entry
- napi_poll
- net_dev_queue

I'm using  2.12.14.

Do you have any idea?

Regards,
