* libtraceevent: Allow custom libdir pathSudip Mukherjee2019-12-162-4/+6
| | | | | | | | | | | | | | | | | | | | | | | When I use prefix=/usr and try to install libtraceevent in my laptop it tries to install in /usr/lib64. I am not having any folder as /usr/lib64 and also the debian policy doesnot allow installing in /usr/lib64. It should be in /usr/lib/x86_64-linux-gnu/. Quote: No package for a 64 bit architecture may install files in /usr/lib64/ or in a subdirectory of it. ref: https://www.debian.org/doc/debian-policy/ch-opersys.html Make it more flexible by allowing to mention libdir_relative while installing so that distros can mention the path according to their policy or use the default one.

* libtraceevent: Fix header installationSudip Mukherjee2019-11-221-4/+4
| | | | | | | | | | | | | | | | | | | | | When we passed some location in DESTDIR, install_headers called do_install with DESTDIR as part of the second argument. But do_install is again using '$(DESTDIR_SQ)$2', so as a result the headers were installed in a location $DESTDIR/$DESTDIR. In my testing I passed DESTDIR=/home/sudip/test and the headers were installed in: /home/sudip/test/home/sudip/test/usr/include/traceevent. Lets remove DESTDIR from the second argument of do_install so that the headers are installed in the correct location.

* libtraceevent, perf tools: Changes in tep_print_event_* APIsTzvetomir Stoyanov2019-09-014-197/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Libtraceevent APIs for printing various trace events information are complicated, there are complex extra parameters. To control the way event information is printed, the user should call a set of functions in a specific sequence. These APIs are reimplemented to provide a more simple interface for printing event information. Removed APIs: tep_print_event_task() tep_print_event_time() tep_print_event_data() tep_event_info() tep_is_latency_format() tep_set_latency_format() tep_data_latency_format() tep_set_print_raw() A new API for printing event information is introduced: void tep_print_event(struct tep_handle *tep, struct trace_seq *s, struct tep_record *record, const char *fmt, ...); where "fmt" is a printf-like format string, followed by the event fields to be printed. Supported fields: TEP_PRINT_PID, "%d" - event PID TEP_PRINT_CPU, "%d" - event CPU TEP_PRINT_COMM, "%s" - event command string TEP_PRINT_NAME, "%s" - event name TEP_PRINT_LATENCY, "%s" - event latency TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be specified as part of this format string: "%precision.divisord". Example: "%3.1000d" - divide the time by 1000 and print the first 3 digits before the dot. Thus, the time stamp "123456000" will be printed as "123.456" TEP_PRINT_INFO, "%s" - event information. TEP_PRINT_INFO_RAW, "%s" - event information, in raw format. Example: tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s", TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU, TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO); Output: ls-11314 [005] d.h. 185207.366383 function __wake_up Signed-off-by: Tzvetomir Stoyanov <tstoyanov@vmware.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: linux-trace-devel@vger.kernel.org Cc: Patrick McLean <chutzpah@gentoo.org> Link: http://lore.kernel.org/linux-trace-devel/20190801074959.22023-2-tz.stoyanov@gmail.com Link: http://lore.kernel.org/lkml/20190805204355.041132030@goodmis.org Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
* tools lib traceevent: Remove unneeded qsort and uses memmove insteadSteven Rostedt (VMware)2019-08-291-6/+49
| | | | | | | | | | | | | | | | | | | | | | While reading a trace data file that had 100,000s of tasks, the process took an extremely long time. I profiled it down to add_new_comm(), which was doing a qsort() call on an array that was pretty much already sorted (all but the last element. qsort() isn't very efficient when dealing with mostly sorted arrays, and this definitely showed its issues. When adding a new task to the task list, instead of using qsort(), do another bsearch() with a function that will find the element before where the new task will be inserted in. Then simply shift the rest of the array, and insert the task where it belongs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libtraceevent from pevent to tep "pevent" to "tep" renaming of: - all "pevent" input arguments of libtraceevent internal functions. - all local "pevent" variables of libtraceevent. This makes the implementation consistent with the chosen naming convention, tep (trace event parser), and will avoid any confusion with the old pevent name Signed-off-by: Tzvetomir Stoyanov <tstoyanov@vmware.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lore.kernel.org/linux-trace-devel/20190401132111.13727-5-tstoyanov@vmware.com Link: http://lkml.kernel.org/r/20190401164344.944953447@goodmis.org Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
