* perf tools: Make binary data printer code in trace_event public availableWang Nan2016-02-241-27/+48
| | | | | | | | | | | | | | | | Move code printing binray data from trace_event() to utils.c and allows passing different printer. Further commits will use this logic to print bpf output event.

* perf data: Add perf data to CTF conversion supportJiri Olsa2015-02-251-0/+2

This patch adds support for CTF format conversion. To convert perf.data into CTF run: $ perf data convert --to-ctf=./ctf-data/ [ perf data convert: Converted 'perf.data' into CTF data './ctf-data/' ] [ perf data convert: Converted and wrote 11.268 MB (100230 samples) ] The command will create CTF metadata out of perf.data file (or one specified via -i option) and then convert all sample events into single CTF stream. Each sample_type bit is translated into separated CTF event field apart from following exceptions: PERF_SAMPLE_RAW - added in next patch PERF_SAMPLE_READ - TODO PERF_SAMPLE_CALLCHAIN - TODO PERF_SAMPLE_BRANCH_STACK - TODO PERF_SAMPLE_REGS_USER - TODO PERF_SAMPLE_STACK_USER - TODO $ perf --debug=data-convert=2 data convert ...

* perf tools: Allow to force redirect pr_debug to stderr.Andi Kleen2014-11-241-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging the tui browser I find it useful to redirect the debug log into a file. Currently it's always forced to the message line. Add an option to force it to stderr. Then it can be easily redirected. Example: [root@zoo ~]# perf --debug stderr report -vv 2> /tmp/debug [root@zoo ~]# tail /tmp/debug dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory dso open failed, mmap: No such file or directory Using /root/.debug/.build-id/4e/841948927029fb650132253642d5dbb2c1fb93 for symbols Failed to open /tmp/perf-8831.map, continuing without symbols Failed to open /tmp/perf-12721.map, continuing without symbols Failed to open /tmp/perf-6966.map, continuing without symbols Failed to open /tmp/perf-8802.map, continuing without symbols [root@zoo ~]# Signed-off-by: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1416605880-25055-2-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | In commit e2f4351 "perf ui/helpline: Introduce ui_helpline__vshow()" the test for the browser used made ui_helpline__vshow() to be called only for the GTK browser. The TUI one then was not used and vfprintf(stderr, ...) was used instead, making the TUI scroll the screen instead of just printing on the last line. Fix it by doing the proper check, that is to call ui_helpline__vshow to be called for both the TUI and GTK browsers.

* perf tui: Fix last use_browser problem related to .perfconfigArnaldo Carvalho de Melo2010-05-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we moved to using ~/.perfconfig to set the value of use_browser, it changed from a boolean to an int so that the convention used for use_pager was followed. That convention is: -1: unspecified, that is what use_{browser,pager} is initialized 0: Don't use the browser (should be TUI), because was explicitely set to 0/off/false on ~/.perfconfig [tui] cmd =, or because we're redirecting the stdout to a file or piping it to some other command (!isatty()). 1: Use the TUI Some code was not properly audited and continued testing it as a boolean, this seems to be the last one.

* perf: Fix endianness argument compatibility with OPT_BOOLEAN() and introduce ↵Ian Munsie2010-04-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OPT_INCR() Parsing an option from the command line with OPT_BOOLEAN on a bool data type would not work on a big-endian machine due to the manner in which the boolean was being cast into an int and incremented. For example, running 'perf probe --list' on a PowerPC machine would fail to properly set the list_events bool and would therefore print out the usage information and terminate. This patch makes OPT_BOOLEAN work as expected with a bool datatype. For cases where the original OPT_BOOLEAN was intentionally being used to increment an int each time it was passed in on the command line, this patch introduces OPT_INCR with the old behaviour of OPT_BOOLEAN (the verbose variable is currently the only such example of this). I have reviewed every use of OPT_BOOLEAN to verify that a true C99 bool was passed. Where integers were used, I verified that they were only being used for boolean logic and changed them to bools to ensure that they would not be mistakenly used as ints. The major exception was the verbose variable which now uses OPT_INCR instead of OPT_BOOLEAN. Signed-off-by: Ian Munsie <imunsie@au.ibm.com> Acked-by: David S.

* perf report: Implement initial UI using newtArnaldo Carvalho de Melo2010-03-121-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newt has widespread availability and provides a rather simple API as can be seen by the size of this patch. The work needed to support it will benefit other frontends too. In this initial patch it just checks if the output is a tty, if not it falls back to the previous behaviour, also if newt-devel/libnewt-dev is not installed the previous behaviour is maintaned. Pressing enter on a symbol will annotate it, ESC in the annotation window will return to the report symbol list. More work will be done to remove the special casing in color_fprintf, stop using fmemopen/FILE in the printing of hist_entries, etc. Also the annotation doesn't need to be done via spawning "perf annotate" and then browsing its output, we can do better by calling directly the builtin-annotate.c functions, that would then be moved to tools/perf/util/annotate.c and shared with perf top, etc But lets go by baby steps, this patch already improves perf usability by allowing to quickly do annotations on symbols from the report screen and provides a first experimentation with libnewt/TUI integration of tools. Tested on RHEL5 and Fedora12 X86_64 and on Debian PARISC64 to browse a perf.data file collected on a Fedora12 x86_64 box.

| | | | | | | | | | | | | | | | | Librarize trace_event() helper so that perf trace can use it too. Also clean up the debug.h includes a bit. It's not good to have it included in perf.h because it doesn't make it flexible against other headers it may need (headers that can also depend on perf.h and then create a recursive header dependency).
