hi,
this is follow up on original RFC patchset:
  http://marc.info/?t=140732735600004&r=1&w=2

Basically we are adding 'perf data convert' command to
allow conversion of perf data file into CTF [1] data.

v3 changes:
  - rebased to latest acme's perf/core

v2 changes:
  - addressed comments from Namhyung
  - rebased to latest acme's perf/core

Changes from RFC:
  - able to generate CTF data, that are possible to be displayed under
    tracecompas GUI [3], please check several screenshots in here [4]
  - storing CTF data streams per cpu
  - several cleanups

Examples:
- Catch default perf data (cycles event):
  $ perf record ls
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.012 MB perf.data (~546 samples) ]

- To display converted CTF data run [2]:
  $ babeltrace ./ctf-data/
  [03:19:13.962125533] (+?.?????????) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 1 }
  [03:19:13.962130001] (+0.000004468) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 1 }
  [03:19:13.962131936] (+0.000001935) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 8 }
  [03:19:13.962133732] (+0.000001796) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 114 }
  [03:19:13.962135557] (+0.000001825) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 2087 }
  [03:19:13.962137627] (+0.000002070) cycles: { }, { ip = 0xFFFFFFFF81361938, tid = 20714, pid = 20714, period = 37582 }
  [03:19:13.962161091] (+0.000023464) cycles: { }, { ip = 0xFFFFFFFF8124218F, tid = 20714, pid = 20714, period = 600246 }
  [03:19:13.962517569] (+0.000356478) cycles: { }, { ip = 0xFFFFFFFF811A75DB, tid = 20714, pid = 20714, period = 1325731 }

- To get some nice output in tracecompas GUI [3], please capture sched:*
  and syscall tracepoints like:
  # perf record -e 'sched:*,raw_syscalls:*' -a
  ^C[ perf record: Woken up 0 times to write data ]
  [ perf record: Captured and wrote 412.347 MB perf.data (~18015721 samples) ]

- To convert perf data file run:
  # perf data convert --to-ctf=./ctf 
  [ perf data convert: Converted 'perf.data' into CTF data './ctf' ]
  [ perf data convert: Converted and wrote 408.421 MB (3964792 samples) ]

- To display converted CTF data run [2]:
  # babeltrace ./ctf-data/

Adding feature check for babeltrace library [1], which will be
used for perf data file CTF [2] conversion in following patches.

The babeltrace library is now automatically detected as standard
feature. It's possible to specify LIBBABELTRACE_DIR make variable
to specify location of installed libbabeltrace, like:

  $ make LIBBABELTRACE_DIR=/opt/libbabeltrace/
    BUILD:   Doing 'make -j4' parallel build

  Auto-detecting system features:
  ...                         dwarf: [ on  ]
  ...                         glibc: [ on  ]

  ...                     libpython: [ on  ]
  ...                      libslang: [ on  ]
  ...                     libunwind: [ on  ]
  ...                 libbabeltrace: [ on  ]
  ...            libdw-dwarf-unwind: [ on  ]
  ...                          zlib: [ on  ]
  ...     DWARF post unwind library: libunwind

Adding new 'perf data' command to provide operations over
data files.

The 'perf data convert' sub command is coming in following
patch, but there's possibility for other useful commands
like 'perf data ls' (to display perf data file in directory
in ls style).

Adding 'perf data convert' to convert perf data file into
different format. 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 ...

The converted CTF data could be analyzed by CTF tools, like
babletrace or tracecompass [1].

  $ babeltrace ./ctf-data/
  [03:19:13.962125533] (+?.?????????) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 1 }

The following members to the ctf-environment were decided
to be added to distinguish and specify perf CTF data:
  - domain
    It says "kernel" because it contains a kernel trace (not to be
    confused with a user space like lttng-ust does)
  - tracer_name
    It says perf. This can be used to distinguish between lttng and
    perf CTF based trace.
  - version
    The kernel version from stream. In addition to release, this is
    what it looks like on a Debian kernel:
      release = "3.14-1-amd64";
      version = "3.14.0";

+COMMANDS
+--------
+convert::
+	Converts perf data file into another format (only CTF [1] format is support by now).
+	It's possible to set data-convert debug variable to get debug messages from conversion,
+	like:
+	  perf --debug data-convert data convert ...
+
+OPTIONS for 'convert'
+---------------------
+--to-ctf::
+	Triggers the CTF conversion, specify the path of CTF data directory.

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

Some of the tracers bring their own id or pid fields and we can end up
having two of them. This patch adds a "perf_" prefix to the 'generic'
fields so we avoid a clash of the member names.

The change is visible in the babeltrace output:

Before:
  $ babeltrace ./ctf-data/
  [03:19:13.962131936] (+0.000001935) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 8 }
  [03:19:13.962133732] (+0.000001796) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 114 }
  ...

Now:
  $ babeltrace ./ctf-data/
  [03:19:13.962131936] (+0.000001935) cycles: { }, { perf_ip = 0xFFFFFFFF8105443A, perf_tid = 20714, perf_pid = 20714, perf_period = 8 }
  [03:19:13.962133732] (+0.000001796) cycles: { }, { perf_ip = 0xFFFFFFFF8105443A, perf_tid = 20714, perf_pid = 20714, perf_period = 114 }

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

Adding support to convert tracepoint event fields into CTF
event fields.

We parse each tracepoint event for CTF conversion and add
tracepoint fields as regular CTF event fields, so they
appear in babeltrace output like:

  $ babeltrace ./ctf-data/
  ...
  [09:02:00.950703057] (+?.?????????) sched:sched_stat_runtime: { }, { perf_ip = ... SNIP ... common_type = 298, common_flags = 1, \
  common_preempt_count = 0, common_pid = 31813, comm = "perf", pid = 31813, runtime = 458800, vruntime = 52059858071 }
  ...

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

Currently we store the data into single data strea/file. The cpu
if data is stored within the event sample. The lttng puts the CPU
number that belongs to the event into the packet context instead
into the event.

This patch makes sure that the trace produce by perf does look the
same way. We now use one stream per-CPU. Having it all in one stream
increased the total size of the resulting file. The test went from
416KiB (with perf_cpu event member) to 24MiB due to the required
(and pointless) flush. With the per-cpu streams the total size went
up to 588KiB.

For big data files the size of data allocated for stream
instance could get really high. It's needed to flush the
data out of the stream once in a while.

Unfortunately there's no size indication in the stream
object, so we govern the flush based on the number of
stored events. Current flush limit is set ot 100000
events.

Adding support to limit the size of ordered_events queue,
so we could control allocation size of perf data files
without proper finished round events.

Hi,

I'm a developer for the Trace Compass tool (see links [3], [4] in Jiri's 
email). I can confirm that the generated CTF can be read correctly by 
our tool, which enables many views and analyses (Control Flow, CPU usage 
view, etc.) that were previously only available for LTTng traces.

Some of our users also use perf extensively, and are looking forward to 
this feature! Is there any ETA as to when this will be merged upstream?

Thanks,
Alexandre

even on this HEAD I'm still getting the 3rd issue I described in earlier email:

    ---
    the bt_ctf_trace_create_stream function tries to set ID on
    stream_class which gets frozen just few moments ago in
    bt_ctf_stream_create call..

    this trigers failure and close up of stream fd which is not set yet:

        if (close(stream->pos.fd)) {
                perror("close");
        }

    hence the 'close: Bad file descriptor' message
    so this one looks like a bug to me, but we might be misusing the API also..
    ---

I need attached patch in perf code.. any idea?

thanks,
jirka

I have merged a patch addressing this problem. Thanks for reporting!

commit 29d9d76c476cbf3fdf6fa709bfbdc24309974f06
Author: Jérémie Galarneau <jeremie.galarneau@efficios.com>
Date:   Wed Jan 28 16:52:28 2015 -0500

    Fix: lock stream class after assigning stream id

    Fixes a bug that was introduced by 2f100782 which made it possible
    to set custom stream class IDs.

    The stream class is frozen when a stream of its type is instanciated.
    However, the trace or writer must still assign a unique ID to the stream
    class if none were set prior. This modification moves the stream class
    locking (freeze) after the ID assignment check.
