[PATCH 01/13] perf tools: Enable close-on-exec flag on perf file descriptor

[Jiri Olsa]

From: Yann Droneaud <ydroneaud@opteya.com>

In commit a21b0b354d4a ('perf: Introduce a flag to enable
close-on-exec in perf_event_open()'), flag PERF_FLAG_FD_CLOEXEC
was added to perf_event_open(2) syscall to allows userspace
to atomically enable close-on-exec behavor when creating
the file descriptor.

This patch makes perf tools use the new flag if supported
by the kernel, so that the event file descriptors got
automatically closed if perf tool exec a sub-command.

From: Andi Kleen <ak@linux.intel.com>

I need a JSON parser. This adds the simplest JSON
parser I could find -- Serge Zaitsev's jsmn `jasmine' --
to the perf library. I merely converted it to (mostly)
Linux style and added support for non 0 terminated input.

The parser is quite straight forward and does not
copy any data, just returns tokens with offsets
into the input buffer. So it's relatively efficient
and simple to use.

The code is not fully checkpatch clean, but I didn't
want to completely fork the upstream code.

Original source: http://zserge.bitbucket.org/jsmn.html

In addition I added a simple wrapper that mmaps a json
file and provides some straight forward access functions.

Used in follow-on patches to parse event files.

[PATCH 06/13] perf tools: Allow events with dot

[Jiri Olsa]

From: Andi Kleen <ak@linux.intel.com>

The Intel events use a dot to separate event name and unit mask.
Allow dot in names in the scanner, and remove special handling
of dot as EOF. Also remove the hack in jevents to replace dot
with underscore. This way dotted events can be specified
directly by the user.

I'm not fully sure this change to the scanner is correct
(what was the dot special case good for?), but I haven't
found anything that breaks with it so far at least.

[PATCH 07/13] perf tools: Add support for reading JSON event files

[Jiri Olsa]

From: Andi Kleen <ak@linux.intel.com>

Add a parser for Intel style JSON event files. This allows
to use an Intel event list directly with perf. The Intel
event lists can be quite large and are too big to store
in unswappable kernel memory.

The parser code knows how to convert the JSON fields
to perf fields. The conversion code is straight forward.
It knows (very little) Intel specific information, and can be easily
extended to handle fields for other CPUs.

The parser code is partially shared with an independent parsing
library, which is 2-clause BSD licenced. To avoid any conflicts I marked
those files as BSD licenced too. As part of perf they become GPLv2.

The events are handled using the existing alias machinery.

We output the BriefDescription in perf list.

Right now the json file can be specified as an argument
to perf stat/record/list. Followon patches will automate this.

JSON files look like this:

[
  {
    "EventCode": "0x00",
    "UMask": "0x01",
    "EventName": "INST_RETIRED.ANY",
    "BriefDescription": "Instructions retired from execution.",
    "PublicDescription": "Instructions retired from execution.",
    "Counter": "Fixed counter 1",
    "CounterHTOff": "Fixed counter 1",
    "SampleAfterValue": "2000003",
    "MSRIndex": "0",
    "MSRValue": "0",
    "TakenAlone": "0",
    "CounterMask": "0",
    "Invert": "0",
    "AnyThread": "0",
    "EdgeDetect": "0",
    "PEBS": "0",
    "PRECISE_STORE": "0",
    "Errata": "null",
    "Offcore": "0"
  }

[PATCH 08/13] perf tools: Automatically look for event file name for cpu

[Jiri Olsa]

From: Andi Kleen <ak@linux.intel.com>

When no JSON event file is specified automatically look
for a suitable file in ~/.cache/pmu-events. A "perf download" can
automatically add files there for the current CPUs.

This does not include the actual event files with perf,
but they can be automatically downloaded instead
(implemented in the next patch)

This has the advantage that the events can be always uptodate,
because they are freshly downloaded. In oprofile we always
had problems with out of date or incomplete events files.

The event file format is per architecture, but can be
extended for other architectures.

[PATCH 09/13] perf tools: Add perf download to download event files

[Jiri Olsa]

From: Andi Kleen <ak@linux.intel.com>

Add a downloader to automatically download the right
files from a download site.

This is implemented as a script calling curl, similar to
perf archive. The perf driver automatically calls the right
binary. The downloader is extensible, but currently only
implements an Intel event download.  It would be straightforward
to add other sites too for other vendors.

The downloaded event files are put into ~/.cache/pmu-events, where the
builtin event parser in util/* can find them automatically.

+perf-download - Download event files for current CPU.

+SYNOPSIS
+--------
+[verse]
+'perf download' [vendor-family-model]
+
+DESCRIPTION
+-----------
+This command automatically downloads the event list for the current CPU and
+stores them in $XDG_CACHE_HOME/pmu-events (or $HOME/.cache/pmu-events).
+The other tools automatically look for them there. The CPU can be also
+specified at the command line.
+
+The downloading is done using http through wget, which needs
+to be installed. When behind a firewall the proxies
+may also need to be set up using "export https_proxy=...."
+
+The user should regularly call this to download updated event lists
+for the current CPU.
+
+Note the downloaded files are stored per user, so if perf is
+used as both normal user and with sudo the event files may
+also need to be moved to root's home directory with
+sudo mkdir /root/.cache ; sud cp -r ~/.cache/pmu-events /root/.cache
+after downloading.

[PATCH 10/13] perf tools: Query terminal width and use in perf list

[Jiri Olsa]

From: Andi Kleen <ak@linux.intel.com>

Automatically adapt the now wider and word wrapped perf list
output to wider terminals. This requires querying the terminal
before the auto pager takes over, and exporting this
information from the pager subsystem.

[PATCH 12/13] perf tests: Add test case for alias and JSON parsing

[Jiri Olsa]

From: Andi Kleen <ak@linux.intel.com>

Add a simple test case to perf test that runs perf download and parses
all the available events, including json events.

This needs adding an all event iterator to pmu.c

[PATCH 13/13] perf tools: Add a --no-desc flag to perf list

[Jiri Olsa]

From: Andi Kleen <ak@linux.intel.com>

Add a --no-desc flag to perf list to not print the event descriptions
that were earlier added for JSON events. This may be useful to
get a less crowded listing.

It's still default to print descriptions as that is the more useful
default for most users.

Before:

% perf list
...
  baclears.any                                       [Counts the total number when the front end is
                                                      resteered, mainly when the BPU cannot provide a
                                                      correct prediction and this is corrected by other
                                                      branch handling mechanisms at the front end]
  br_inst_exec.all_branches                          [Speculative and retired branches]

After:

% perf list --no-desc

'A download site' is way too vague and detached from the perf project.

We want these description files to be in the perf source code, 
somewhere in tools/perf/live-config/arch/x86/ or so, and installed 
during 'make install' - i.e. part of perf project and installed in 
~/.debug or ~/.perf or so.

Those files could be refreshed via 'perf download' and could be 
accessible via kernel.org as well, 'perf download' should pick up 
these files from Linus's latest git repository (via the HTTP 
namespace).

Thanks,

	Ingo

So basically instead of the above URI, we want these files to be 
refreshed from:

    http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/tools/perf/live-config/

I don't think that's a good idea. It would recreate all the 
problems oprofile has with out of date event lists. Already
proven to not work well.

I have doubts a gitweb server is a good way to distribute potentially
high volume / high access data.

However getting a more neutral space is fine.

It would be fine to put it elsewhere on kernel.org.
I can ask for a space.

Otherwise I will just remove the auto URL from the tool, 
so the perf project does not need to endorse any particular
event lists.

Let me know what you prefer. I'll assume the "remove the URL"
variant is the default option.

That's true only if you ignore my second suggestion:

I don't buy that concern either, because typically humans will trigger 
the refresh - just like clicking on a link to refresh. In any case, if 
it starts being a problem in practice we can reconsider, it's not a 
reason to not do it.

The beauty of my approach is to:

 1) integrate the descriptions into the project, so that developers 
    are well aware of them and keep them uptodate - while considering 
    all the other perf features the kernel may offer.

 2) have them update automatically as we update the primary source, in 
    a single place.

Your suggestions so far lose those benefits, unnecessarily, and 
without explanation given.

So unless you can come up with a better approach, this is the way to 
implement this feature.

Thanks,

	Ingo

Surely the shipped versions should go in /usr/share/perf or something like
that? Rather than a particular users home directory?

This version would go in ~/.perf or similar.

Another benefit of having the events installed as part of perf is that they are
usable on machines that don't have access to the internet.

Even if some of the event descriptions are out of date, that is still
preferable to having no events on such machines.

[GIT PULL 00/13] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 7f16023bfcc4b1f2bbccf86219dc97473db6e0d6:

  perf python: Use -Wno-redundant-decls to build with PYTHON=python3 (2018-09-19 10:25:13 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf test:

- Add watchpoint entry (Ravi Bangoria)

Build fixes:

- Initialize perf_data_file fd field to fix building the CTF (trace format)
  converter with with gcc 4.8.4 on Ubuntu 14.04 (Jérémie Galarneau)

- Use -Wno-redundant-decls to build with PYTHON=python3 to
  build the python binding, fixing the build in systems such
  as Clear Linux (Arnaldo Carvalho de Melo)

Hardware tracing:

- Suppress AUX/OVERWRITE records (Alexander Shishkin)

Infrastructure:

- Adopt PTR_ERR_OR_ZERO from the kernel and use it in
  the bpf-loader instead of open coded equivalent (Ding Xiang)

- Improve the event ordering code to make it clear and fix
  a bug related to freeing of events when using pipe mode
  from 'record' to 'inject' (Jiri Olsa)

- Some prep work to facilitate per-cpu threads to write
  record data to per-cpu files (Jiri Olsa)

Test results:

The first ones are container (docker) based builds of tools/perf with
and without libelf support.  Where clang is available, it is also used
to build perf with/without libelf, and building with LIBCLANGLLVM=1
(built-in clang) with gcc and clang when clang and its devel libraries
are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The Clear Linux container is building with NO_CLANG=1, the problem preventing
its use has been identified and the next builds will build in ClearLinux with
both gcc and clang. This time around only gcc was used.

  perf annotate browser: Help for cycling thru hottest instructions with TAB/shift+TAB (2017-09-01 14:55:40 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

- Support syscall name glob matching in 'perf trace' (Arnaldo Carvalho de Melo)

  e.g.:

   # perf trace -e pkey_*
   32.784 (0.006 ms): pkey/16018 pkey_alloc(init_val: DISABLE_WRITE) = -1 EINVAL Invalid argument
   32.795 (0.004 ms): pkey/16018 pkey_mprotect(start: 0x7f380d0a6000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
   32.801 (0.002 ms): pkey/16018 pkey_free(pkey: -1                ) = -1 EINVAL Invalid argument
   ^C#

- Do not auto merge counts for explicitely specified events in
  'perf stat' (Arnaldo Carvalho de Melo)

- Fix syntax in documentation of .perfconfig intel-pt option (Jack Henschel)

- Calculate the average cycles of iterations for loops detected by the
  branch history support in 'perf report' (Jin Yao)

- Support PERF_SAMPLE_PHYS_ADDR as a sort key "phys_daddr" in the 'script', 'mem',
  'top' and 'report'. Also add a test entry for it in 'perf test' (Kan Liang)

- Fix 'Object code reading' 'perf test' entry in PowerPC (Ravi Bangoria)

- Remove some duplicate Power9 duplicate vendor events (described in JSON
  files) (Sukadev Bhattiprolu)

- Add help entry in the TUI annotate browser about cycling thru hottest
  instructions with TAB/shift+TAB (Arnaldo Carvalho de Melo)

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf
commands with a variety of command line event specifications to then
intercept the sys_perf_event syscall to check that the perf_event_attr
fields are set up as expected, among a variety of other unit tests.

The 'perf test'  also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.

Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf
commands with a variety of command line event specifications to then
intercept the sys_perf_event syscall to check that the perf_event_attr
fields are set up as expected, among a variety of other unit tests.

The 'perf test'  also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.

Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

For this specific pull request the samples/bpf/ was disabled, as 'make headers_install'
is failing with the following error, in this case in fedora:rawhide:

    INSTALL usr/include/uapi/ (0 file)
  /git/linux/scripts/Makefile.headersinst:62: *** Missing generated UAPI file ./arch/x86/include/generated/uapi/asm/unistd_32.h.  Stop.
  make[1]: *** [/git/linux/Makefile:1151: headers_install] Error 2
  make[1]: Leaving directory '/tmp/build/linux'
  make: *** [Makefile:152: sub-make] Error 2
  make: Leaving directory '/git/linux'

I'll investigate later, perf and objtool builds just fine, with clang and gcc.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

[GIT PULL 00/13] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo

Test results at the end of this message, as usual.

* The following description will move to the end in the next pull requests *

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The following changes since commit ad5013d5699d30ded0cdbbc68b93b2aa28222c6e:

  perf/x86/intel: Use ULL constant to prevent undefined shift behaviour (2017-01-11 16:43:30 +0100)

  tools: Sync x86's vmx.h with the kernel (2017-01-11 16:48:02 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

New features:

- Add more triggers to switch the output file (perf.data.TIMESTAMP).

  Now, in addition to switching to a different output file when
  receiving a SIGUSR2, one can also specify file size and time based
  triggers:

       perf record -a --switch-output=signal

  is equivalent to what we had before:

       perf record -a --switch-output

  While we can also ask for the file to be "sliced" by size, taking
  into account that that will happen only when we get woken up by
  the kernel, i.e. one has to take into account the --mmap-pages (the
  size of the perf mmap ring buffer):

       perf record -a --switch-output=2G

  will break the perf.data output into multiple files limited to 2GB
  of samples, right when generating the output.

  For time based samples, alert() will be used, so to have 1 minute
  limited perf.data output files:

      perf record -a --switch-output=1m

  (Jiri Olsa)

- Remove the need to use -e only for syscalls and --event only for
  tracepoints/HW/SW/etc events, i.e. now one can use:

      perf trace -e nanosleep,futex,sched:sched_switch ./workload

  or:

      perf trace --event nanosleep,futex,sched:sched_switch ./workload

  And have it tracing raw_syscalls:sys_{enter,exit} for the nanosleep
  and futex syscalls, formatting those as strace does while also
  tracing sched:sched_switch, ordering it all into one strace like
  output.

  Using '!' as the first character in the -e/--event argument remains
  a way to negate the list of syscalls, i.e. all syscalls except for
  the ones specified, doesn't affect the other kinds of events.

  E.g:

  [root@jouet ~] # perf trace -e sched:sched_switch,nanosleep usleep 1
     0.000 ( 0.028 ms): usleep/28150 nanosleep(rqtp: 0x7ffe4201b9f0) ...
     0.028 (         ): sched:sched_switch:usleep:28150 [120] S ==> swapper/0:0 [120])
     0.000 ( 0.065 ms): usleep/28150  ... [continued]: nanosleep()) = 0

  tools build: Add feature detection for g++ (2016-10-05 19:59:35 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

- Intel PT timestamp fixes (Adrian Hunter)

- Fix Intel JSON fixed counter conversions (Andi Kleen)

- Sync memcpy, cpufeatures and bpf headers with the kernel (Arnaldo Carvalho de Melo)

- Add some more tool tips (Donghyun Kim, Kim SeonYoung, Nambong Ha)

- Fix libtraceevent's kbuffer_read_at_offset() handling of offsets before or
  equal the first event (Namhyung Kim)

- Fix uretprobe probe placement on ppc64le (Ravi Bangoria)

- Support building C++ source files and add feature detection for g++,
  prep work for supporting a builtin clang/llvm, to remove the need for having
  that toolchain installed to automagically build BPF scriptlets that then
  gets uploaded to the kernel via sys_bpf() (Wang Nan)

  perf tests: Do not use sizeof on pointer type (2016-04-28 15:37:52 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Allow generate timestamped suffixed multiple perf.data files upon receiving
  SIGUSR2 in 'perf record', to slice a long running monitoring session, allowing
  to dump uninteresting sessions (Wang Nan)

- Handle ENOMEM for perf_event_max_stack + PERF_SAMPLE_CALLCHAIN
  in perf_evsel__open_strerror(), showing a more informative
  message when the request call stack depth can't be allocated by
  the kernel (Arnaldo Carvalho de Melo)

Infrastructure:

- Use strbuf for making strings in 'perf probe' (Masami Hiramatsu)

- Do not use sizeof on pointer type, not a problem since its a pointer to
  pointer, fix none the less. Found by Coccinelle (Vaishali Thakkar)

Cleanups:

- Fix for Coverity found issues in the bpf feature build test (Florian Fainelli)

Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

----------------------------------------------------------------
Arnaldo Carvalho de Melo (3):
      perf evsel: Handle ENOMEM for perf_event_max_stack + PERF_SAMPLE_CALLCHAIN
      perf evsel: Remove two extraneous ending newlines in open_strerror()
      perf trace: Move msg_flags beautifier to tools/perf/trace/beauty/

Florian Fainelli (2):
      bpf tools: Remove expression with no effect
      bpf tools: Fix syscall argument

Masami Hiramatsu (1):
      perf probe: Use strbuf for making strings

Vaishali Thakkar (1):
      perf tests: Do not use sizeof on pointer type

Wang Nan (6):
      perf tools: Introduce trigger class
      perf tools: Derive trigger class from auxtrace_snapshot
      perf record: Split output into multiple files via '--switch-output'
      perf record: Force enable --timestamp-filename when --switch-output is provided
      perf record: Disable buildid cache options by default in switch output mode
      perf record: Generate tracking events for process forked by perf

Hi Ingo,

	Please consider applying,

The following changes since commit 5f1230c9b80b89f404938ff88dfa64a963f74f2c:

  Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2015-08-12 12:16:11 +0200)

  perf tests: Add tests to callgraph and time parse (2015-08-12 13:20:29 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Allow selecting the type of callchains per event, including disabling
  callchains in all but one entry in an event list, to save space, and also
  to ask for the callchains collected in one event to be used in other
  events (Kan Liang)

- Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho de Melo)
  - A bunch more translate file/pathnames from pointers to strings
  - Convert numbers to strings for the 'keyctl' syscall 'option' arg.
  - Add missing 'clockid' entries

- Fix 'perf probe -L sys_*' as it was not showing all the source code for
  syscall functions in the kernel (Masami Hiramatsu)

- Make ESC unzoom as well in the hists browser, i.e. in 'report' and 'top',
  as we're considering repurposing the right and left arrow keys to use in
  horizontal scrolling, i.e. leave just ESC to be used for what <- works
  now, and ENTER for what -> does (they are already aliases for ages)
  (Arnaldo Carvalho de Melo)

Infrastructure fixes:

- Check for SRCLINE_UNKNOWN case in "srcfile" processing (Andi Kleen)

- Wrap the slsmg_{printf,write_nstring} slang functions behing ui_browser, so
  that we can make the ui_browser based browsers (annotate, menus, hists, etc) UI
  library agnostic and usable with multiple backends (slang now, GTK+ and others
  in the future, maybe) (Arnaldo Carvalho de Melo)

  perf bench futex: Add lock_pi stresser (2015-07-20 17:49:51 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

New features:

- Allow filtering perf's pid via 'perf record --exclude-perf' (Wang Nan)

- 'perf trace' now supports syscall groups, like strace, i.e:

    $ trace -e file touch file

  Will expand 'file' into multiple, file related, syscalls. More work needed to
  add extra groups for other syscall groups, and also to complement what was
  added for the 'file' group, included as a proof of concept. (Arnaldo Carvalho de Melo)

- Add lock_pi stresser to 'perf bench futex', to test the kernel code
  related to FUTEX_(UN)LOCK_PI (Davidlohr Bueso)

User visible fixes:

- Apply --filter to all events in a glob matching, not just the last one (Wang Nan)

Documentation:

- Document setting '-e pmu/period=N/' in the 'perf record' man page (Kan Liang)

Infrastructure:

- 'perf probe' code simplifications and movements to separate files (Masami Hiramatsu)

- Fix makefile generation under 'dash' (Sergei Trofimovich)

Agreed, some more work is needed to change that message in more places,
will do it eventually.

Pulled, thanks a lot Arnaldo!

Btw., one small thing I noticed about the status line in perf top: if I ever use 
'f' to freeze/unfreeze events, the following message:

  Press 'f' to disable the events or 'h' to see other hotkeys

sticks around forever, even after I look into annotation and exit it, etc.

So I don't mind some default, helpful message there (such as 'Press 'h' to see 
hotkeys'), but it appears this particular message is context and usage sensitive, 
which wasn't really the goal, right?

Thanks,

	Ingo

  perf tools: Allow auxtrace data alignment (2015-06-23 18:28:37 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Move toggling event logic from 'perf top' and into hists browser, allowing
  freeze/unfreeze with event lists with more than one entry (Namhyung Kim)

- Add missing newlines when dumping PERF_RECORD_FINISHED_ROUND and
  showing the Aggregated stats in 'perf report -D' (Adrian Hunter)

Infrastructure:

- Allow auxtrace data alignment (Adrian Hunter)

- Allow events with dot (Andi Kleen)

- Fix failure to 'perf probe' events on arm (He Kuang)

- Add testing for Makefile.perf (Jiri Olsa)

- Add test for make install with prefix (Jiri Olsa)

- Fix single target build dependency check (Jiri Olsa)

- Access thread_map entries via accessors, prep patch to hold more info per
  entry, for ongoing 'perf stat --per-thread' work (Jiri Olsa)

- Use __weak definition from compiler.h (Sukadev Bhattiprolu)

- Split perf_pmu__new_alias() (Sukadev Bhattiprolu)

Something like this might prevent Ingo's error message:

Date: Wed, 10 Sep 2014 16:14:50 +0300
Subject: [PATCH] perf tools: Do not attempt to run perf-read-vdso32 if it
 wasn't built

popen() causes an error message to print if perf-read-vdso32
does not run.  Avoid that by not trying to run it if it was
not built.  Ditto perf-read-vdsox32.

Ok, those don't apply, as it expects other stuff, that you sent before,
but were not processed yet, to be in place, I'm fixing it up.

Yeah, I should've tested this more, will make sure I test these things
this time.

Having a requirement that for each new feature we need an entry in 'perf
test' and/or in make -C tools/perf build-test seems a bit harsh, but
would be ideal, hook that to 'git request-pull' and this would hopefully
only happen every celestial aligment nights or so :-\

I pulled it locally then unpulled as it didn't pass my (very

No problem, the good thing is that we're almost getting it all in. I'll
rework the branch and resubmit, Ingo, is that OK with you? Or have you
already pulled and we should instead send a patch on top, fixing the
problem?

I am very sorry Arnaldo but 2 patches are older versions, namely:

	perf tools: Build programs to copy 32-bit compatibility VDSOs
	perf tools: Add support for 32-bit compatibility VDSOs

Up-to-date versions can be found from 15 August:

	patchwork:

		https://patchwork.kernel.org/patch/4729131/
		https://patchwork.kernel.org/patch/4729111/

	marc.info:

		http://marc.info/?l=linux-kernel&m=140812995414607&w=4
		http://marc.info/?l=linux-kernel&m=140812993814585&w=4

It looks like I reposted older versions by mistake on 31 July.
Very sorry :-(

The originals were changed as described here:

We are not relying on it in the sense the 'record' works without it.
There is more explanation in "perf tools: Build programs to copy 32-bit
compatibility VDSOs" and "perf tools: Add support for 32-bit compatibility
VDSOs" (although those are the wrong versions of those patches - I will send
another email about that in a moment).

Presumably perf-read-vdso32 is not in the PATH.  Did you 'make install'?

Hm, so I'm getting this error, when trying to profile a 32-bit 
ELF binary on a 64-bit kernel, on a testbox:

 $ perf record ~/hackbench  10
 Time: 0.115
 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.373 MB perf.data (~16279 samples) ]
 sh: perf-read-vdso32: command not found

comet:~/tip> file ~/hackbench 
/home/mingo/hackbench: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, not stripped

64-bit executables work fine:

 $ perf record perf bench sched pipe
 # Running 'sched/pipe' benchmark:
 # Executed 1000000 pipe operations between two processes

      Total time: 13.374 [sec]

       13.374352 usecs/op
           74769 ops/sec
 [ perf record: Woken up 14 times to write data ]
 [ perf record: Captured and wrote 3.602 MB perf.data (~157354 samples) ]

The kernel is an older one:

Hi Ingo,

	Please consider pulling,

The following changes since commit 197749981e539c1eb5863f417de6dd4e2c02b76c:

  Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2014-01-14 17:25:12 +0100)

  tools lib traceevent: fix pointer-integer size mismatch (2014-01-15 17:04:38 -0300)

----------------------------------------------------------------
Changes in user visible interfaces:

. Rename 'record's --no-delay option to --no-buffering, better reflecting its
  purpose and freeing up '--delay' to take the place of '--initial-delay', so that
  'record' and 'stat' are consistent.

Refactorings:

. Get rid of die() and friends (good riddance!) in libtraceevent (Namhyung Kim)

Developer stuff:

. Fix cross build problems related to pkgconfig and CROSS_COMPILE not being
  propagated to the feature tests, leading to features being tested in the
  host and then being enabled on the target. (Mark Rutland)

. Fix pointer-integer size mismatch in some libtraceevent plugins (Mark Rutland)

. Fix build error due to zfree() cast (Namhyung Kim)
