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,
