Hi,
I have read the Documentation/trace/tracepoints.txt file.
I modified my code to acknowledge it.
I am again unable to list my tracepoints using lttng list . (I also
tried lttng enable-channel before...).
So , only one step I have not made :
Is it mandatory to register the probe functions ???
Regards,
S.Ancelot

Hi Stéphane,
We're going to need more details than that. Which kernel version are you using?
Can you see the other kernel events in your trace? If not, can you
show us how you are setting up your session?
Thanks,
Jérémie

Hi,
I am trying to reimplement LTTNG 2. in xenomai api.
the main problem is that I do not sea any of my new events available in
lttng 2.
my kernel compiles fine and here is what I done to set it up :
file include/trace/events/pod.h :
#undef TRACE_SYSTEM
#define TRACE_SYSTEM xenotrace
#if !defined(_XENOTRACE_H) || defined(TRACE_HEADER_MULTI_READ)
#define _XENOTRACE_H
#include <linux/tracepoint.h>
TRACE_EVENT( xn_nucleus_thread_init,
TP_PROTO(struct xnthread *thread,char *thread_name,xnflags_t
flags,const char *class,int prio),
TP_ARGS(thread,thread_name,flags,class,prio),
TP_STRUCT__entry(
__field(struct xnthread *,thread)
__array(char ,thread_name, XNOBJECT_NAME_LEN )
__field(xnflags_t,flags)
__array(char,class, XNOBJECT_NAME_LEN )
__field(int, prio )
),
TP_fast_assign(
__entry->thread = thread;
memcpy(__entry->thread_name,thread_name, XNOBJECT_NAME_LEN);
__entry->flags = flags;
memcpy(__entry->class,class, XNOBJECT_NAME_LEN);
__entry->prio = prio;
),
TP_printk("thread %p thread_name %s flags %lu class %s prio
%d",
__entry->thread, __entry->thread_name,
__entry->flags,__entry->class,
__entry->prio)
);
#endif
/* This part must be outside protection */
#include <trace/define_trace.h>
in pod.h :
#define CREATE_TRACE_POINTS
#include <trace/events/pod.h>
