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>
