[PATCH 01/18] perf annotate: Remove unused hist_entry__annotate function

[Arnaldo Carvalho de Melo]

From: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com>

hist_entry__annotate looks part of API but I don't find any caller
of this function. Removing it.

[PATCH 03/18] perf annotate: Generalize handling of 'ret' instructions

[Arnaldo Carvalho de Melo]

From: "Naveen N. Rao" <naveen.n.rao@linux.vnet.ibm.com>

Introduce helper to detect 'ret' instructions and use the same in the TUI.
A helper is needed since some architectures such as powerpc have more
than one return instruction.

[PATCH 04/18] perf tools: Add more toolchain triplets

[Arnaldo Carvalho de Melo]

From: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com>

Add few more triplets based on Fedora and Ubuntu binutils (cross tools).

Before applying patch on x86:

  ( Install binutils-powerpc64-linux-gnu.x86_64 )
  $ perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc \
      --objdump powerpc64-linux-gnu-objdump

After applying patch on x86:

  $ perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc

I.e. it will find the right objdump from the environment data recorded
in the perf.data file + these triplets.

[PATCH 05/18] 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)];
+};

+
+	HEADER_VERSION = 5,

+A perf_header_string with the exact CPU type. On x86 this is
+vendor,family,model,stepping. For example: GenuineIntel,6,69,1
+

+An uint64_t with the total memory in bytes.
+

+
+This is an array of perf_event_attrs, each attr_size bytes long, which defines

+description.
+
+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)

+References:

+include/uapi/linux/perf_event.h
+
+This is the canonical description of the kernel generated perf_events
+and the perf_event_attrs.
+
+perf_events manpage
+
+A manpage describing perf_event and perf_event_attr is here:
+http://web.eece.maine.edu/~vweaver/projects/perf_events/programming.html
+This tends to be slightly behind the kernel include, but has better
+descriptions.  An (typically older) version of the man page may be
+included with the standard Linux man pages, available with "man
+perf_events"
+
+pmu-tools
+
+https://github.com/andikleen/pmu-tools/tree/master/parser
+
+A definition of the perf.data format in python "construct" format is available
+in pmu-tools parser. This allows to read perf.data from python and dump it.
+
+quipper
+
+The quipper C++ parser is available at
+https://chromium.googlesource.com/chromiumos/platform/chromiumos-wide-profiling/
+Unfortunately this parser tends to be many versions behind and may not be able
+to parse data files generated by recent perf.

[PATCH 06/18] perf build: Add libbabeltrace to build-test

[Arnaldo Carvalho de Melo]

From: Wang Nan <wangnan0@huawei.com>

'make build-test' doesn't test LIBBABELTRACE=1. It misses a building
failure caused by commit 41840d211c51 ("perf config: Move config
declarations from util/cache.h to util/config.h"), breaks bisect.

Add LIBBABELTRACE=1 to build-test.

[PATCH 08/18] perf record: Move mmap setup block to separate function

[Arnaldo Carvalho de Melo]

From: Wang Nan <wangnan0@huawei.com>

Following commits introduce multiple evlists to record. This patch
extracts perf_evlist__mmap_ex() processing to a new function, creates
record__mmap() and record__mmap_evlist() to wrap perf_evlist__mmap_ex()
and its error processing. They will be improvemented to create mmap for
all evlists.

The reason was a typo that passed global 'name' variable as the
is_regular_file argument instead dso->long_name.

[PATCH 13/18] perf data ctf: Pass convert options through opts structure

[Arnaldo Carvalho de Melo]

From: Wang Nan <wangnan0@huawei.com>

Following commits will add new option to 'perf data convert'. All options
should be grouped into a structure and passed to low level converter
(currently there's only one converter).

Introduce data-convert.h and define 'struct perf_data_convert_opts' in
it. Pass 'force' through opts.

From: Wang Nan <wangnan0@huawei.com>

If 'all' option is selected, 'perf data convert' should convert not only
samples, but non-sample events such as comm and fork. Add this option in
perf_data_convert_opts. Following commits will add cmdline option to
select it.

[PATCH 15/18] perf data ctf: Prepare collect non-sample events

[Arnaldo Carvalho de Melo]

From: Wang Nan <wangnan0@huawei.com>

Following commits are going to allow 'perf data convert' to collect not
only samples, but also non-sample events like comm and fork. In this
patch we count non-sample events using c.non_sample_count, and prepare
to print number of both type of events like:

  # ~/perf data convert --all --to-ctf ./out.ctf
  [ perf data convert: Converted 'perf.data' into CTF data './out.ctf' ]
  [ perf data convert: Converted and wrote 0.846 MB (6508 samples, 686 non-samples) ]

[PATCH 16/18] perf data ctf: Generate comm event to CTF output

[Arnaldo Carvalho de Melo]

From: Wang Nan <wangnan0@huawei.com>

If 'all' is selected, convert comm event to output CTF stream.

setup_non_sample_events() is called if non_sample is selected. It
creates a comm_class for comm event.

Use macros to generate and process_comm_event and add_comm_event. These
macros can be reused for other non-sample events.

Ok, I've created a perf-core-for-mingo-20160628 with that patch removed
while we investigate this, please consider pulling that one instead.

build-test should've caught this... Reproduced, trying to fix...

So, when doing the docs install it expects files starting with perf-*
will be fed to asciidoc to generate man pages, etc, so the quick fix
here is to rename perf-file-format.txt to perf.data-file-format.txt,
which I did, so this will go in the next pull request.

Volunteers accepted to turn this into asciidoc format so that we can do
a man perf-data-file-format or somesuch.

  perf tools: Fix kernel_start for PTI on x86 (2018-05-19 06:42:51 -0300)

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

- Record min/max LBR cycles (>= skylake) and add 'perf annotate' TUI
  hotkey to show it (c) (Jin Yao)

- Fix machine->kernel_start for PTI on x86 (Adrian Hunter)

- Make machine->env->arch always available, e.g. in 'perf top', not
  just when reading that info from perf.data files (Adrian Hunter)

- Reduce the number of files read at 'perf' start, leaving information such as
  cacheline size, tracefs mount point determination, max_stack, etc, to be
  lazily read as tools needs then (Arnaldo Carvalho de Melo)

- Fixup BPF include and examples install messages (Arnaldo Carvalho de Melo)

- Fixup callchain addresses and symbol offsets in 'perf script', to help
  correlating with objdump output (Sandipan Das)

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.

  perf tools: Fix kernel_start for PTI on x86 (2018-05-19 06:42:51 -0300)

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

- Record min/max LBR cycles (>= skylake) and add 'perf annotate' TUI
  hotkey to show it (c) (Jin Yao)

- Fix machine->kernel_start for PTI on x86 (Adrian Hunter)

- Make machine->env->arch always available, e.g. in 'perf top', not
  just when reading that info from perf.data files (Adrian Hunter)

- Reduce the number of files read at 'perf' start, leaving information such as
  cacheline size, tracefs mount point determination, max_stack, etc, to be
  lazily read as tools needs then (Arnaldo Carvalho de Melo)

- Fixup BPF include and examples install messages (Arnaldo Carvalho de Melo)

- Fixup callchain addresses and symbol offsets in 'perf script', to help
  correlating with objdump output (Sandipan Das)

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.

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.

[GIT PULL 00/18] 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 9df9078ef2086652647248ee6e82ca8f661cb3f5:

  perf/amd/uncore: Fix pr_fmt() prefix (2017-04-11 08:44:59 +0200)

  perf annotate: Use stripped line instead of raw disassemble line (2017-04-11 16:22:23 -0300)

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

User visible:

- Support s390 jump instructions in perf annotate (Christian Borntraeger)

- When failing to setup multiple events (e.g. '-e irq_vectors:*'), state
  which one caused the failure (Yao Jin)

- Various fixes for pipe mode, where the output of 'perf record' is
  written to stdout instead of to a perf.data file, fixing workloads
  such as: (David Carrillo-Cisneros)

    $ perf record -o - noploop | perf inject -b > perf.data

    $ perf record -o - noploop | perf annotate

Infrastructure:

- Simplify ltrim() implementation (Arnaldo Carvalho de Melo)

- Use ltrim() and rtrim() in places where ad-hoc equivalents were being
  used (Taeung Song)

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.

Pulled, thanks a lot Arnaldo!

Note, there was a conflict in tools/perf/util/annotate.c due to the s390 fix in 
perf/urgent. I've fixed it up, but please double check the conflict resolution I 
made in 43d5b075c400.

Thanks,

	Ingo

  perf record: Honor --quiet option properly (2017-02-20 11:50:36 -0300)

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

New features:

- Make -a/--all-cpus be the default target in 'perf record' and 'perf stat',
  just like it is with 'perf trace' (Jiri Olsa)

- Introduce -q/--quiet to the 'annotate', 'diff' and 'report', fix up
  its behaviour in 'record'. This makes the output more compact by
  elliminating headers, leaving just the histogram lines (Namhyung Kim)

Fixes:

- Handle offline/absent CPUs (Jan Stancek)

Infrastructure:

- Filter out -specs=/a/b/c from CC options when building the python
  support, allowing that feature to be built with clang (Arnaldo Carvalho de Melo)

- Fix DEBUG=1 build with clang (Arnaldo Carvalho de Melo)

Trivial:

- Fix spelling of 'preempt' in a libtraceevent function name (Steven Rostedt)

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

----------------------------------------------------------------
Arnaldo Carvalho de Melo (3):
      tools perf scripting python: clang doesn't have -spec, remove it
      perf python: Filter out -specs=/a/b/c from the python binding cc options
      perf session: Fix DEBUG=1 build with clang

Jan Stancek (3):
      perf cpumap: Add cpu__max_present_cpu()
      perf header: Make build_cpu_topology skip offline/absent CPUs
      perf tools: Replace _SC_NPROCESSORS_CONF with max_present_cpu in cpu_topology_map

Jiri Olsa (5):
      perf build: Add special fixdep cleaning rule
      perf tools: Move new_term arguments into struct parse_events_term template
      perf tools: Fail on using multiple bits long terms without value
      perf stat: Add -a as default target
      perf record: Add -a as default target

Namhyung Kim (6):
      perf utils: Add perf_quiet_option()
      perf utils: Check verbose flag properly
      perf report: Add -q/--quiet option

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.

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 sched timehist: Add -V/--cpu-visual option (2016-11-23 10:44:09 -0300)

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

New tool:

- 'perf sched timehist' provides an analysis of scheduling events.

  Example usage:
      perf sched record -- sleep 1
      perf sched timehist

  By default it shows the individual schedule events, including the wait
  time (time between sched-out and next sched-in events for the task), the
  task scheduling delay (time between wakeup and actually running) and run
  time for the task:

        time    cpu  task name         wait time  sch delay  run time
                     [tid/pid]            (msec)     (msec)    (msec)

  ...

  Times are in msec.usec. (David Ahern, Namhyung Kim)

Improvements:

- Make 'perf c2c report' support -f/--force, to allow skipping the
  ownership check for root users, for instance, just like the other
  tools (Jiri Olsa)

- Allow sorting cachelines by total number of HITMs, in addition to
  local and remote numbers (Jiri Olsa)

Fixes:

- Make sure errors aren't suppressed by the TUI reset at the end of
  a 'perf c2c report' session (Jiri Olsa)

Infrastructure:

- Initial work on having the annotate code better support multiple
  architectures, including the ability to cross-annotate, i.e. to
  annotate perf.data files collected on an ARM system on a x86_64
  workstation (Arnaldo Carvalho de Melo, Ravi Bangoria, Kim Phillips)

- Use USECS_PER_SEC instead of hard coded number in libtraceevent (Steven Rostedt)

- Add retrieval of preempt count and latency flags in libtraceevent (Steven Rostedt)

[GIT PULL 00/18] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo

The following changes since commit a11c51acc52822754d66a11c15f6f6edd4d23c55:

  Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2015-07-21 07:58:06 +0200)

are available in the git repository at:

  perf script: Add option --show-switch-events (2015-07-23 22:51:14 -0300)

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

New features:

- Introduce PERF_RECORD_SWITCH(_CPU_WIDE) and use it in 'record' to
  ask for context switches, allowing non priviledged tasks to know
  when they are switched in and out, which wasn't possible with
  the other context switch tracepoint and software events, see the
  patch description for a comprehensive justification (Adrian Hunter)

- Stop collecting /proc/kallsyms in perf.data files, saving about
  4.5MB on a typical x86-64 system, use the symbol resolution
  routines used in all the other tools (report, top, etc) now that
  we can ask libtraceevent to use perf's symbol resolution code.
  (Arnaldo Carvalho de Melo)

User visible fixes:

- Expose perf's symbol resolver to libtraceecent, so that its plugins can
  resolve tracepoint fields to kernel functions, like the 'function' field
  in the "timer:hrtimer_start tracepoint" (Arnaldo Carvalho de Melo)

Infrastructure:

- Map propagation of thread and cpu maps improvements, prep work for
  'perf stat' new features (Jiri Olsa)

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

----------------------------------------------------------------
Adrian Hunter (5):
      perf: Add PERF_RECORD_SWITCH to indicate context switches
      perf tools: Add new PERF_RECORD_SWITCH event
      perf record: Add option --switch-events to select PERF_RECORD_SWITCH events
      perf script: Don't assume evsel position of tracking events
      perf script: Add option --show-switch-events

Arnaldo Carvalho de Melo (8):

  perf bench numa: Share sched_getcpu() __weak def with cloexec.c (2015-05-18 12:36:46 -0300)

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

User visible:

- Fix "Command" sort_entry's cmp and collapse function (Jiri Olsa)

- Load map's symtab before 'perf probe' glob matching (Wang Nan)

- Set vmlinux_path__nr_entries to 0 in vmlinux_path__exit, to fix
  the use case where this code is called multiple times, which wasn't
  that common when it was introduced but seems to be now (Wang Nan).

Infrastructure:

- Protect dso symtab and cache operations with a mutex (Namhyung Kim)

- Make all refcnt operations use atomic.h (Arnaldo Carvalho de Melo)

- Install libtraceevent.a into libdir (Wang Nan)

Build fixes:

- Fix one build failure on RHEL5 by making 'perf bench numa' use the
  __weak sched_getcpu() provided by cloexec.h (Arnaldo Carvalho de Melo)

- Fix dwarf-aux.c compilation on i386 (Jiri Olsa)

  Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent (2014-12-12 09:09:52 +0100)

  perf symbols: Fix use after free in filename__read_build_id (2014-12-16 13:38:28 -0300)

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

User visible:

- The mmap address range for the ring buffer now is calculated using the
  contents of /proc/sys/kernel/perf_event_mlock_kb.

  This fixes an -EPERM case where 'trace' was trying to use more than what
  configured on perf_event_mlock_kb. (Arnaldo Carvalho de Melo)

Infrastructure:

- Move bitops definitions so that they match the header file hierarchy
  in the kernel sources where that code came from. (Arnaldo Carvalho de Melo)

- Adopt round{down,up}_pow_of_two from the kernel and use it instead of
  equivalent code, so that we reuse more kernel code and make tools/ look
  more like kernel source code, to encourage further contributions from
  kernel hackers (Arnaldo Carvalho de Melo)

- Fix use after free in filename__read_build_id (Mitchell Krome)

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

----------------------------------------------------------------

Ingo,

	Please consider pulling the perf-core-for-mingo-2 signed tag
instead, it is exactly the same content modulo removal of some
whitespaces at the end of a few lines in tools/perf/Makefile.perf that
Jiri found while reading those patches,

Thanks,

- Arnaldo
