[PATCH 01/11] perf tools: Add documentation for perf.data on disk format

[Arnaldo Carvalho de Melo]

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

Add some documentation for the on disk format of perf.data. This is not
documenting the actual perf events -- which are documented in
perf_event.h -- but just the additional headers that perf record adds
around them when writing the data to disk.

+perf.data format
+
+Uptodate as of v4.7
+
+This document describes the on-disk perf.data format, generated by perf record
+or perf inject and consumed by the other perf tools.
+
+On a high level perf.data contains the events generated by the PMUs, plus metadata.
+
+All fields are in native-endian of the machine that generated the perf.data.
+
+When perf is writing to a pipe it uses a special version of the file
+format that does not rely on seeking to adjust data offsets.  This
+format is not described here. The pipe version can be converted to
+normal perf.data with perf inject.
+
+The file starts with a perf_header:
+
+struct perf_header {
+	char magic[8];		/* PERFILE2 */
+	uint64_t size;		/* size of the header */
+	uint64_t attr_size;	/* size of an attribute in attrs */
+	struct perf_file_section attrs;
+	struct perf_file_section data;
+	struct perf_file_section event_types;
+	uint64_t flags;
+	uint64_t flags1[3];
+};
+
+The magic number identifies the perf file and the version. Current perf versions
+use PERFILE2. Old perf versions generated a version 1 format (PERFFILE). Version 1
+is not described here. The magic number also identifies the endian. When the
+magic value is 64bit byte swapped compared the file is in non-native
+endian.
+
+A perf_file_section contains a pointer to another section of the perf file.
+The header contains three such pointers: for attributes, data and event types.
+
+struct perf_file_section {
+	uint64_t offset;	/* offset from start of file */
+	uint64_t size;		/* size of the section */
+};
+
+Flags section:
+
+The header is followed by different optional headers, described by the bits set
+in flags. Only headers for which the bit is set are included. Each header
+consists of a perf_file_section located after the initial header.
+The respective perf_file_section points to the data of the additional
+header and defines its size.
+
+Some headers consist of strings, which are defined like this:
+
+struct perf_header_string {
+       uint32_t len;
+       char string[len]; /* zero terminated */
+};
+
+Some headers consist of a sequence of strings, which start with a
+
+struct perf_header_string_list {
+     uint32_t nr;
+     struct perf_header_string strings[nr]; /* variable length records */
+};
+
+The bits are the flags bits in a 256 bit bitmap starting with
+flags. These define the valid bits:
+
+	HEADER_RESERVED		= 0,	/* always cleared */
+	HEADER_FIRST_FEATURE	= 1,
+	HEADER_TRACING_DATA	= 1,
+
+Describe me.
+
+	HEADER_BUILD_ID = 2,
+
+The header consists of an sequence of build_id_event. The size of each record
+is defined by header.size (see perf_event.h). Each event defines a ELF build id
+for a executable file name for a pid. An ELF build id is a unique identifier
+assigned by the linker to an executable.
+
+struct build_id_event {
+	struct perf_event_header header;
+	pid_t			 pid;
+	uint8_t			 build_id[24];
+	char			 filename[header.size - offsetof(struct build_id_event, filename)];

+
+Data
+
+This section is the bulk of the file. It consist of a stream of perf_events
+describing events. This matches the format generated by the kernel.
+See perf_event.h or the manpage for a detailed description.
+
+Some notes on parsing:
+
+Ordering
+
+The events are not necessarily in time stamp order, as they can be
+collected in parallel on different CPUs. If the events should be
+processed in time order they need to be sorted first. It is possible
+to only do a partial sort using the FINISHED_ROUND event header (see
+below). perf record guarantees that there is no reordering over a
+FINISHED_ROUND.
+
+ID vs IDENTIFIER
+
+When the event stream contains multiple events each event is identified
+by an ID. This can be either through the PERF_SAMPLE_ID or the
+PERF_SAMPLE_IDENTIFIER header. The PERF_SAMPLE_IDENTIFIER header is
+at a fixed offset from the event header, which allows reliable
+parsing of the header. Relying on ID may be ambigious.
+IDENTIFIER is only supported by newer Linux kernels.
+
+Perf record specific events:
+
+In addition to the kernel generated event types perf record adds its
+own event types (in addition it also synthesizes some kernel events,
+for example MMAP events)

[PATCH 04/11] perf annotate: Simplify header dotted line sizing

[Arnaldo Carvalho de Melo]

From: "Peter Zijlstra (Intel)" <peterz@infradead.org>

No need to use strlen, etc to figure that out, just use the return from
printf(), it will tell how wide the following line needs to be.

[PATCH 05/11] perf annotate: Add number of samples to the header

[Arnaldo Carvalho de Melo]

From: "Peter Zijlstra (Intel)" <peterz@infradead.org>

Staring at annotations of large functions is useless if there's only a
few samples in them. Report the number of samples in the header to make
this easier to determine.

Committer note:

The change amounts to:

  - Percent | Source code & Disassembly of perf-vdso.so for cycles:u
  ------------------------------------------------------------------
  + Percent | Source code & Disassembly of perf-vdso.so for cycles:u (3278 samples)

[PATCH 08/11] perf tools: Allow to reset open files counter

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

I hit a bug when running test suite without forking
each test (-F option):

  $ perf test -F dso
   8: Test dso data read                                       : Ok
   9: Test dso data cache                                      : FAILED!
  10: Test dso data reopen                                     : FAILED!

The reason the session file limit is set just once for
perf process so we need to reset it for each test,
otherwise wrong limit is taken into account.

[PATCH 09/11] perf tests: Fix thread map test for -F option

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

I hit a bug when running test suite without forking each test (-F
option):

  $ perf test -Fv
  ...
  34: Test thread map                                          :
  --- start ---
  FAILED tests/thread-map.c:24 wrong comm
  ---- end ----
  Test thread map: FAILED!

The reason was the process name wasn't 'perf' as expected by the test,
because other tests set the name as well.

Setting it explicitly now.

Pulled, thanks a lot Arnaldo!

Btw., the build started generating:

 Warning: x86_64's syscall_64.tbl differs from kernel

Due to:

Yeah, I noticed that, that is a compat one (the non-compat ones are
already in sync), which is something 'perf trace' needs to support but
can't right now due to raw_syscalls:sys_{enter,exit} limitations, so not
that important right now, will fix it anyway to remove the warning,

Thanks!

[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, more to come as I go thru Adrian's x86
PTI series and the C++ support improvements to 'perf probe', from
Holger,

Best Regards,

  perf bpf: Fix NULL return handling in bpf__prepare_load() (2018-05-16 10:01:55 -0300)

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

- Add '-e intel_pt//u' test to the 'parse-events' 'perf test' entry,
  to help avoiding regressions in the events parser such as one
  that caused a revert in v4.17-rc (Arnaldo Carvalho de Melo)

- Fix NULL return handling in bpf__prepare_load() (YueHaibing)

- Warn about 'perf buildid-cache --purge-all' failures (Ravi Bangoria)

- Add infrastructure to help in writing eBPF C programs to be used
  with '-e name.c' type events in tools such as 'record' and 'trace',
  with headers for common constructs and an examples directory that
  will get populated as we add more such helpers and the 'perf bpf'
  branch that Jiri Olsa has been working on (Arnaldo Carvalho de Melo)

- Handle uncore event aliases in small groups properly (Kan Liang)

- Use the "_stest" symbol to identify the kernel map when loading kcore (Adrian Hunter)

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.

[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, more to come as I go thru Adrian's x86
PTI series and the C++ support improvements to 'perf probe', from
Holger,

Best Regards,

- Arnaldo

  perf bpf: Fix NULL return handling in bpf__prepare_load() (2018-05-16 10:01:55 -0300)

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

- Add '-e intel_pt//u' test to the 'parse-events' 'perf test' entry,
  to help avoiding regressions in the events parser such as one
  that caused a revert in v4.17-rc (Arnaldo Carvalho de Melo)

- Fix NULL return handling in bpf__prepare_load() (YueHaibing)

- Warn about 'perf buildid-cache --purge-all' failures (Ravi Bangoria)

- Add infrastructure to help in writing eBPF C programs to be used
  with '-e name.c' type events in tools such as 'record' and 'trace',
  with headers for common constructs and an examples directory that
  will get populated as we add more such helpers and the 'perf bpf'
  branch that Jiri Olsa has been working on (Arnaldo Carvalho de Melo)

- Handle uncore event aliases in small groups properly (Kan Liang)

- Use the "_stest" symbol to identify the kernel map when loading kcore (Adrian Hunter)

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.

[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, more to come as I go thru Adrian's x86
PTI series and the C++ support improvements to 'perf probe', from
Holger,

Best Regards,

- Arnaldo

  perf bpf: Fix NULL return handling in bpf__prepare_load() (2018-05-16 10:01:55 -0300)

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

- Add '-e intel_pt//u' test to the 'parse-events' 'perf test' entry,
  to help avoiding regressions in the events parser such as one
  that caused a revert in v4.17-rc (Arnaldo Carvalho de Melo)

- Fix NULL return handling in bpf__prepare_load() (YueHaibing)

- Warn about 'perf buildid-cache --purge-all' failures (Ravi Bangoria)

- Add infrastructure to help in writing eBPF C programs to be used
  with '-e name.c' type events in tools such as 'record' and 'trace',
  with headers for common constructs and an examples directory that
  will get populated as we add more such helpers and the 'perf bpf'
  branch that Jiri Olsa has been working on (Arnaldo Carvalho de Melo)

- Handle uncore event aliases in small groups properly (Kan Liang)

- Use the "_stest" symbol to identify the kernel map when loading kcore (Adrian Hunter)

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.

[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	There are some 'perf test' and container failures, but those
don't seem to have been introduced by patches in this series and are
being investigated.

	Please consider pulling,

- Arnaldo

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.

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.

- Fix concat_probe_trace_events() in 'perf probe', it should dereference a
  pointer, not test its value (Ravi Bangoria)

User visible:

- Handle partial AUX records, checking if 'kvm_intel.ko' is loaded and
  if its 'vmm_exclusive' parameter is set to 0, suggesting tweaking
  it to reduce gaps (Alexander Shishkin)

Infrastructure:

- Sync the kvm.h, cpufeatures.h and perf_event.h tools/ headers copies
  with the kernel (Arnaldo Carvalho de Melo, Alexander Shishkin)

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.

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.

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

Fixes:

- Fix concat_probe_trace_events() in 'perf probe', it should dereference a
  pointer, not test its value (Ravi Bangoria)

User visible:

- Handle partial AUX records, checking if 'kvm_intel.ko' is loaded and
  if its 'vmm_exclusive' parameter is set to 0, suggesting tweaking
  it to reduce gaps (Alexander Shishkin)

Infrastructure:

- Sync the kvm.h, cpufeatures.h and perf_event.h tools/ headers copies
  with the kernel (Arnaldo Carvalho de Melo, Alexander Shishkin)

- 'perf lock' subcommands should include common options, using
  OPT_PARENT() (Changbin Du)

- Ditto for 'perf timechart' (Arnaldo Carvalho de Melo)

Documentation:

  Correct 'perf stat --no-aggr' description (Ravi Bangoria)

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.

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 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo

Build news:

Now the 16.04-x-armhf and 16.04-x-powerpc64 cross build docker images have libz
and libelf cross built from sources, so that we can cover cross build testing
more of the codebase.

In those images objtool is not built, as checking powerpc and arm binaries is
not supported, so trying to build it will end up in linker errors.

So, here is a new pull req, removing the following patch, due to that
segfault you noticed while testing 'perf top' on an ubuntu system:
 
> He Kuang (2):
>       perf tools: Find vdso supporting cross-platform analysis

The new tag is perf-core-for-mingo-20160520.

Kuang, Ingo proposed the patch below to fix the problem he noticed
(notice the 'dso && ' part, as __dsos__find() may return NULL), but he
had several other issues with code touched by this patch, I'll try to
address those, please check the patch below and resubmit.

The following changes since commit a29d5c9b8167dbc21a7ca8c0302e3799f9063b4e:

  perf tools: Separate accounting of contexts and real addresses in a stack trace (2016-05-16 23:11:54 -0300)

  perf tools: Set buildid dir under symfs when --symfs is provided (2016-05-19 19:04:36 -0300)

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

User visible:

- We should not use the current value of the kernel.perf_event_max_stack as the
  default value for --max-stack in tools that can process perf.data files, they
  will only match if that sysctl wasn't changed from its default value at the
  time the perf.data file was recorded, fix it.

  This fixes a bug where a 'perf record -a --call-graph dwarf ; perf report'
  produces a glibc invalid free backtrace (Arnaldo Carvalho de Melo)

- Provide a better warning when running 'perf trace' on a system where the
  kernel.kptr_restrict is set to 1, similar to the one produced by 'perf record',
  noticed on ubuntu 16.04 where this is the default kptr_restrict setting.
  (Arnaldo Carvalho de Melo)

- Fix ordering of instructions in the annotation code, noticed when annotating
  ARM binaries, now that table is auto-ordered at first use, to avoid more such
  problems (Chris Ryder)

- Fix searching the vdso image to support cross-platform analysis (He Kuang)

- Set buildid dir under symfs when --symfs is provided (He Kuang)

- Fix the 'exit_group()' syscall output in 'perf trace' (Arnaldo Carvalho de Melo)

- Only auto set call-graph to "dwarf" in 'perf trace' when syscalls are being
  traced (Arnaldo Carvalho de Melo)

Hi Ingo,

The following changes since commit c0edb7467c3d21b213ff734bfe810d81d2c6ed61:

  Merge tag 'perf-core-for-mingo-20160505' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-05-06 08:35:14 +0200)

  perf trace: Move futex_op beautifier to tools/perf/trace/beauty/ (2016-05-06 13:00:59 -0300)

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

User visible:

- Fix ordering of kernel/user entries in 'caller' mode, where the kernel and
  user parts were being correctly inverted but kept in place wrt each other,
  i.e. 'callee' (k1, k2, u3, u4) became 'caller' (k2, k1, u4, u3) when it
  should be 'caller' (u4, u3, k2, k1) (Chris Phlipot)

- In 'perf trace' don't print the raw arg syscall args for a syscall that has
  no arguments, like gettid(). This was happening because just checking if
  the syscall args list is NULL may mean that there are no args (e.g.: gettid)
  or that there is no tracepoint info (e.g.: clone) (Arnaldo Carvalho de Melo)

- Add extra output of counter values with 'perf stat -vv' (Andi Kleen)

Infrastructure:

- Expose callchain db export via the python API (Chris Phlipot)

Code reorganization:

- Move some more syscall arg beautifiers from the 'perf trace' main file to
  separate files in tools/perf/trace/beauty/, to reduce the main file line
  count (Arnaldo Carvalho de Melo)

- Allow requesting that some CPUs or PIDs be highlighted in 'perf sched map' (Jiri Olsa)

- Compact 'perf sched map' to show just CPUs with activity, improving the output
  in high core count systems (Jiri Olsa)

- Fix segfault with 'perf trace --no-syscalls -e syscall-names' by bailing out
  such request, doesn't make sense to ask for no syscalls and then specify which
  ones should be printed (Arnaldo Carvalho de Melo)

[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, this is on top of my previously submitted
acme/perf/urgent, so that we can test Andi's udis86 work on 'perf script'.

	This is now test built in several more docker images, including
minimal feature cross-compiler builds ones:

  # dm
  minimal-debian-experimental-x-mips64: Ok
  minimal-debian-experimental-x-mips64el: Ok
  minimal-debian-experimental-x-mipsel: Ok
  minimal-ubuntu-x-arm: Ok
  minimal-ubuntu-x-arm64: Ok
  minimal-ubuntu-x-ppc64: Ok
  minimal-ubuntu-x-ppc64el: Ok
  alldeps-debian: Ok
  alldeps-mageia: Ok
  alldeps-rhel7: Ok
  alldeps-centos: Ok
  alldeps-opensuse: Ok
  alldeps-ubuntu: Ok
  #

	Those x-arch cross docker images already allow me to avoid introducing
bugs like the powerpc one Sukadev spotted.

	I need to figure out how to install more devel packages for things like
libelf-devel:arch in debian/ubuntu, I almost got there with 'dpkg
--add-architecture arch', but I still need to figure out  how to find the list
of multilib enabled devel packages to allow me to have devel packages for other
arches than the native one...

 	call 0x81c29600
  <SNIP>

- Add support for skipping itrace instructions, useful to fast forward
  processor trace (Intel PT, BTS) to right after initialization code at the start
  of a workload (Andi Kleen)

- Add support for backtraces in perl 'perf script's (Dima Kogan)

- Add -U/-K (--all-user/--all-kernel) options to 'perf mem' (Jiri Olsa)

- Make -f/--force option documentation consistent across tools (Jiri Olsa)

Infrastructure:

- Add 'perf test' to check for event times (Jiri Olsa)

Ok, I inserted Jiri's patch fixing the problem just before the commit
(fa184776ac27) that triggers it, so that we don't break bisection for
human-readable numbers in 'perf stat'.

Its all in a new signed tag, that combines the two outstanding ones
(perf-core-for-mingo-20160229 + perf-core-for-mingo-20160302), please
consider pulling.

following patch fixed that for me..

... see how the numbers became human-unreadable, losing the big-number separator?

Hi Ingo,

	Please consider pulling,

- Arnaldo

The following changes since commit 675965b00d734c985e4285f5bec7e524d15fc4e1:

  perf: Export perf_event_sysfs_show() (2016-02-29 09:35:27 +0100)

  perf record: Ensure return non-zero rc when mmap fail (2016-02-29 12:44:15 -0300)

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

User visible:

- Check existence of frontend/backed stalled cycles in 'perf stat' (Andi Kleen)

- Avoid installing .o files from tools/lib/ into the python extension (Jiri Olsa)

- Rename the tracepoint '/format' field that carries the syscall ID from 'nr',
  that is also the name of some syscalls arguments, to "__syscall_nr", to
  avoid having multiple fields with the same name, that was breaking the
  python script skeleton generator from perf.data files (Taeung Song)

- Support converting data from bpf events in 'perf data' (Wang Nan)

Infrastructure:

- Split libtraceevent's pevent_print_event() (Steven Rostedt)

- Librarize some 'perf record' bits to allow handling multiple perf.data
  files per session (Wang Nan)

- Ensure return non-zero rc when mmap fail in 'perf record' (Wang Nan)

Hi Ingo,

	Please consider pulling,

The following changes since commit 0bd106d26dbe444160104b3153ca1652d2ab913b:

  Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent (2016-01-12 11:01:16 +0100)

  perf tools: Fallback to srcdir/Documentation/tips.txt (2016-01-12 12:42:08 -0300)

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

User visible new features:

- Add --buildid-all option to 'perf record' to avoid processing
  samples, just collecting build-ids for _all_ the DSOs that appears
  in PERF_RECORD_MMAP records (Namhyung Kim)

- Add some more usage tips to appear in the hists browser
  (top & report) (Namhyung Kim, Andi Kleen)

- Fix mmap2 event allocation in synthesize code, where we were
  allocating space just for PERF_RECORD_MMAP, the older variant,
  which could lead to corner case problems (Wang Nan)

Developer stuff:

- Make list.h self-sufficient, removing one more reference to
  kernel headers that lead to recent breakage when some rculist
  change was made in the kernel sources. (Josh Poimboeuf)

  Add missing NORETURN define for parse-options.h in
  tools/lib/subcmd (Josh Poimboeuf)

- Fallback to srcdir/Documentation/ when not finding tips.txt
  elsewhere (Namhyung Kim)

  perf bench sched-messaging: Drop barf() (2014-06-19 16:13:17 -0300)

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

User visible:

. Add --repeat global option to 'perf bench' to be used in benchmarks
  such as the existing 'futex' one, that was modified to use it instead
  of a local option. (Davidlohr Bueso)

. Fix fd -> pathname resolution in 'trace', be it using /proc or
  a vfs_getname probe point. (Arnaldo Carvalho de Melo)

. Add suggestion of how to set perf_event_paranoid sysctl, to help
  non-root users trying tools like 'trace' to get a working environment.
  (Arnaldo Carvalho de Melo)

Fixes:

. Fix memory leak in the 'sched-messaging' perf bench test. (Davidlohr Bueso)

. The -o and -n 'perf bench mem' options are mutually exclusive, emit error
  when both are specified. (Davidlohr Bueso)

. Fix scrollbar refresh row index in the ui browser, problem exposed now
  that headers will be added and will be allowed to be switched on/off.
  (Jiri Olsa)

Cleanups:

. Remove needless reassignments in 'trace' (Arnaldo Carvalho de Melo)

. Cache the is_exit syscall test in 'trace) (Arnaldo Carvalho de Melo)

. No need to reimplement err() in 'perf bench sched-messaging', drop barf().
  (Davidlohr Bueso).

. Remove ev_name argument from perf_evsel__hists_browse, can be obtained
  from the other parameters. (Jiri Olsa)
