2018-08-13tools lib traceevent: Rename static variables and functions in event-parse.cTzvetomir Stoyanov (VMware)1-27/+27
In order to make libtraceevent into a proper library, variables, data structures and functions require a unique prefix to prevent name space conflicts. That prefix will be "tep_" and not "pevent_". This changes static variables and functions in event-parse.c: pevent_func_params, __pevent_parse_format, __pevent_parse_event, pevent_error_str, pevent_search_event Signed-off-by: Tzvetomir Stoyanov (VMware) <tz.stoyanov@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Yordan Karadzhov (VMware) <y.karadz@gmail.com> Cc: linux-trace-devel@vger.kernel.org Link: http://lkml.kernel.org/r/20180808180703.575392642@goodmis.org Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2018-01-17tools lib traceevent: Handle new pointer processing of bprint stringsSteven Rostedt (VMware)1-0/+26
The Linux kernel printf() has some extended use cases that dereference the pointer. This is dangerouse for tracing because the pointer that is dereferenced can change or even be unmapped. It also causes issues when the trace data is extracted, because user space does not have access to the contents of the pointer even if it still exists. To handle this, the kernel was updated to process these dereferenced pointers at the time they are recorded, and not post processed. Now they exist in the tracing buffer, and no dereference is needed at the time of reading the trace. The event parsing library needs to handle this new case.

2016-03-23tools lib traceevent: Remove redundant CPU outputSteven Rostedt1-3/+1
Commit a6745330789f ("tools lib traceevent: Split pevent_print_event() into specific functionality functions") broke apart the function pevent_print_event() into three functions. The first function prints the comm, pid and CPU, the second prints the timestamp. But that commit added the printing of the CPU in the timestamp function, which now causes pevent_print_event() to duplicate the CPU output. Remove the redundant printing of the record's CPU from the timestamp function.

2016-02-29tools lib traceevent: Split pevent_print_event() into specific functionality ↵Steven Rostedt1-32/+104
functions Currently there's a single function that is used to display a record's data in human readable format. That's pevent_print_event(). Unfortunately, this gives little room for adding other output within the line without updating that function call. I've decided to split that function into 3 parts. pevent_print_event_task() which prints the task comm, pid and the CPU pevent_print_event_time() which outputs the record's timestamp pevent_print_event_data() which outputs the rest of the event data. pevent_print_event() now simply calls these three functions. To save time from doing the search for event from the record's type, I created a new helper function called pevent_find_event_by_record(), which returns the record's event, and this event has to be passed to the above functions.
