  perf config: Reimplement show_config() using config_set__for_each (2016-06-23 17:23:00 -0300)

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

New features:

- Add 'callindent' option to 'perf script -F', to indent the Intel PT
  call stack, making this output more ftrace-like (Adrian Hunter, Andi Kleen)

User visible:

- Enlarge 'pid' column width, to cope with large pids (Jiri Olsa)

Infrastructure:

- Cross platform unwind fixes (He Kuang)

- Make destructors accept NULL, behaving like free() (Arnaldo Carvalho de Melo)

- Remove reference to perl interpreted in the recently added 'perf script'
  stackcollapse python script (Arnaldo Carvalho de Melo)

- Rename CLASS__for_each() macros to CLASS__for_each_entry(), to use the
  list_for_each_entry() semantics, as most of these class specific loop helpers
  are list_for_each_entry*() wrappers  (Arnaldo Carvalho de Melo)

- Expose the hist_browser code, will be used with data structures other
  than perf_evsel (Jiri Olsa)

- 'perf config' refactorings (Taeung Song)

[PATCH 01/27] perf script stackcollapse: Remove reference to the perl interpreter

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

It is ignored and this is actually a python script, not a perl one.

[PATCH 04/27] perf hists browser: Introduce struct hist_browser title callback

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

We can now setup title callback for hist_browser, which will be useful
in following changes to create customized hist_browsers.

This also separates struct perf_evsel dependency out of hist_browser
basic code.

[PATCH 08/27] perf hists: Enlarge pid sort entry size

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@kernel.org>

The pid sort entry currently aligns pids with 5 digits, which is not
enough for current 4 million pids limit.

This leads to unaligned ':' header-data output when we display 7 digits
pid:

  # Children      Self  Symbol                    Pid:Command
  # ........  ........  ......................  .....................
  #
       0.12%     0.12%  [.] 0x0000000000147e0f  2052894:krava
  ...

Adding 2 more digit to properly align the pid limit:

  # Children      Self  Symbol                      Pid:Command
  # ........  ........  ......................  .......................
  #
       0.12%     0.12%  [.] 0x0000000000147e0f  2052894:krava

[PATCH 11/27] perf tests time-to-tsc: No need to disable an event before deleting it

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Because at the destructor we will call close() and that will do the
disable. And we destructors can accept NULL, just like free(), so no
need to check it.

[PATCH 13/27] perf tools: Let python use correct gcc for build_ext

[Arnaldo Carvalho de Melo]

From: He Kuang <hekuang@huawei.com>

Currently, python uses host gcc instead of cross-compile gcc in the last
step of compiling build_ext(remove '--quiet' to show verbose):

  cross-gcc ...
  cross-gcc ...
  creating ~/out/python_ext_build/lib
  gcc -pthread -shared -Wl,-z ...

This is wrong but may not cause any errors unless the features detected
by cross-compiler do not match those for host compiler, and causes the
following errors:

  /usr/lib64/gcc/bin/ld: cannot find -lunwind-x86
  collect2: error: ld returned 1 exit status
  error: command 'gcc' failed with exit status 1
  cp: cannot stat ‘~/out/python_ext_build/lib/perf.so’: No such file or directory
  Makefile.perf:257: recipe for target '~/out/python/perf.so' failed
  make[1]: *** [~/out/python/perf.so] Error 1
  Makefile:68: recipe for target 'all' failed
  make: *** [all] Error 2

This issue is also reported and anwsered on stackoverflow.

[PATCH 14/27] perf config: Move config declarations from util/cache.h to util/config.h

[Arnaldo Carvalho de Melo]

From: Taeung Song <treeze.taeung@gmail.com>

Lately util/config.h has been added but util/cache.h has declarations of
functions and a global variable for config features.

To manage codes about configuration at one spot, move them to
util/config.h and let source files that need config features include
config.h And if the source files that included previous cache.h need
only config.h, remove including cache.h.

[PATCH 15/27] perf tools: Find right DSO taking into account if binary is 32 or 64-bit

[Arnaldo Carvalho de Melo]

From: He Kuang <hekuang@huawei.com>

There's a problem in machine__findnew_vdso(), vdso buildid generated by a
32-bit machine stores it with the name 'vdso', but when processing buildid on a
64-bit machine with the same 'perf.data', perf will search for vdso named as
'vdso32' and get failed.

This patch tries to find the existing dsos in machine->dsos by thread dso_type.
64-bit thread tries to find vdso with name 'vdso', because all 64-bit vdso is
named as that. 32-bit thread first tries to find vdso with name 'vdso32' if
this thread was run on 64-bit machine, if failed, then it tries 'vdso' which
indicates that the thread was run on 32-bit machine when recording.

Committer note:

Additional explanation by Adrian Hunter:

We match maps to builds ids using the file name - consider
machine__findnew_[v]dso() called in map__new().  So in the context of a perf
data file, we consider the file name to be unique.

A vdso map does not have a file name - all we know is that it is vdso.  We look
at the thread to tell if it is 32-bit, 64-bit or x32.  Then we need to get the
build id which has been recorded using short name "[vdso]" or "[vdso32]" or
"[vdsox32]".

The problem is that on a 32-bit machine, we use the name "[vdso]".  If you take
a 32-bit perf data file to a 64-bit machine, it gets hard to figure out if
"[vdso]" is 32-bit or 64-bit.

This patch solves that problem.

 ----

This also merges a followup patch fixing a problem introduced by the
original submission of this patch, that would crash 'perf record' when
recording samples for a 32-bit app on a 64-bit system.

[PATCH 16/27] perf unwind: Change macro names of perf register

[Arnaldo Carvalho de Melo]

From: He Kuang <hekuang@huawei.com>

Use macro name prefixed with "LIBUNWIND_ARCH" for better understanding
that the regs used by callbacks of libunwind are arch specific. The real
regs used should be defined in the wrapper file of
"unwind-libunwind-local.c" for each supported arch.

[PATCH 17/27] perf unwind: Fix wrongly used regs for x86_32 unwind

according to the host platform, for remote unwind, we should use
register number for target platform. Fix this by define
LIBUNWIND_ARCH_REG_SP/IP in the wrapper file of x86_32 platform.

[PATCH 18/27] perf unwind: Fix wrongly used regs for aarch64 unwind

[Arnaldo Carvalho de Melo]

From: He Kuang <hekuang@huawei.com>

By default, "unwind-libunwind-local.c" gets SP/IP register number
according to the host platform, for remote unwind, we should use
register number for target platform. Fix this by define
LIBUNWIND_ARCH_REG_SP/IP in the wrapper file of aarch64 platform.

[PATCH 23/27] perf script: Print sample flags more nicely

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

The flags field is synthesized and may have a value when Instruction
Trace decoding. The flags are "bcrosyiABEx" which stand for branch,
call, return, conditional, system, asynchronous, interrupt, transaction
abort, trace begin, trace end, and in transaction, respectively.

Change the display so that known combinations of flags are printed more
nicely e.g.: "call" for "bc", "return" for "br", "jcc" for "bo", "jmp"
for "b", "int" for "bci", "iret" for "bri", "syscall" for "bcs",
"sysret" for "brs", "async" for "by", "hw int" for "bcyi", "tx abrt" for
"bA", "tr strt" for "bB", "tr end" for "bE".

However the "x" flag will be displayed separately in those cases e.g.
"jcc (x)" for a condition branch within a transaction.

Example:

    perf record -e intel_pt//u ls
    perf script --ns -F comm,cpu,pid,tid,time,ip,addr,sym,dso,symoff,flags

[PATCH 24/27] perf auxtrace: Add option to feed branches to the thread stack

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

In preparation for using the thread stack to print an indent
representing the stack depth in perf script, add an option to tell
decoders to feed branches to the thread stack. Add support for that
option to Intel PT and Intel BTS.

The advantage of using the decoder to feed the thread stack is that it
happens before branch filtering and so can be used with different itrace
options (e.g. it still works when only showing calls, even though the
thread stack needs to see calls and returns). Also it does not conflict
with using the thread stack to get callchains.

[PATCH 25/27] perf script: Add callindent option

[Arnaldo Carvalho de Melo]

From: Adrian Hunter <adrian.hunter@intel.com>

Based on patches from Andi Kleen.

When printing PT instruction traces with perf script it is rather useful
to see some indentation for the call tree. This patch adds a new
callindent field to perf script that prints spaces for the function call
stack depth.

We already have code to track the function call stack for PT, that we
can reuse with minor modifications.

The resulting output is not quite as nice as ftrace yet, but a lot
better than what was there before.

Note there are some corner cases when the thread stack gets code
confused and prints incorrect indentation. Even with that it is fairly
useful.

When displaying kernel code traces it is recommended to run as root, as
otherwise perf doesn't understand the kernel addresses properly, and may
not reset the call stack correctly on kernel boundaries.

Example output:

	sudo perf-with-kcore record eg2 -a -e intel_pt// -- sleep 1
	sudo perf-with-kcore script eg2 --ns -F callindent,time,comm,pid,sym,ip,addr,flags,cpu --itrace=cre | less

[PATCH 26/27] perf config: Introduce new init() and exit()

[Arnaldo Carvalho de Melo]

From: Taeung Song <treeze.taeung@gmail.com>

Many sub-commands use perf_config() but everytime perf_config() is
called, perf_config() always read config files.  (i.e. user config
'~/.perfconfig' and system config '$(sysconfdir)/perfconfig')

But it is better to use the config set that already contains all config
key-value pairs to avoid this repetitive work reading the config files
in perf_config(). (the config set mean a static variable 'config_set')

In other words, if new perf_config__init() is called, only first time
'config_set' is initialized collecting all configs from the config
files.  And then we could use new perf_config() like old perf_config().
When a sub-command finished, free the config set by perf_config__exit()
at run_builtin().

If we do, 'config_set' can be reused wherever perf_config() is called
and a feature of old perf_config() is the same as new perf_config() work
without the repetitive work that read the config files.

In summary, in order to use features about configuration,
we can call the functions at perf.c and other source files as below.

    # initialize a config set
    perf_config__init()

    # configure actual variables from a config set
    perf_config()

    # eliminate allocated config set
    perf_config__exit()

    # destroy existing config set and initialize a new config set.
    perf_config__refresh()

[PATCH 27/27] perf config: Reimplement show_config() using config_set__for_each

[Arnaldo Carvalho de Melo]

From: Taeung Song <treeze.taeung@gmail.com>

Recently config_set__for_each got added.  In order to let show_config()
be short and clear, rewrite this function using it.

[GIT PULL 00/27] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, this is on top of
perf-core-for-mingo-4.20-20180919, that is not yet in tip.

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

The following changes since commit 24ef0fd0a1f389b156e6ef0edd71072728831bd9:

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

  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 when building for python3 has been identified and the next builds will
build in ClearLinux with both gcc and clang. This time around only gcc was
used.

[GIT PULL 00/27] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, this is on top of
perf-core-for-mingo-4.20-20180919, that is not yet in tip.

- Arnaldo

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

The following changes since commit 24ef0fd0a1f389b156e6ef0edd71072728831bd9:

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

are available in the Git repository at:

  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 (J?r?mie 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 when building for python3 has been identified and the next builds will
build in ClearLinux with both gcc and clang. This time around only gcc was
used.

[GIT PULL 00/27] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, this is on top of
perf-core-for-mingo-4.20-20180919, that is not yet in tip.

- Arnaldo

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

The following changes since commit 24ef0fd0a1f389b156e6ef0edd71072728831bd9:

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

  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 when building for python3 has been identified and the next builds will
build in ClearLinux with both gcc and clang. This time around only gcc was
used.

[GIT PULL 00/27] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, I'm now investigating why these failed:

  38: LLVM search and compile                               :
  38.1: Basic BPF llvm compile                              : Ok
  38.2: kbuild searching                                    : Ok
  38.3: Compile source for BPF prologue generation          : Ok
  38.4: Compile source for BPF relocation                   : FAILED!
  40: BPF filter                                            :
  40.1: Basic BPF filtering                                 : Ok
  40.2: BPF pinning                                         : Ok
  40.3: BPF prologue generation                             : Ok
  40.4: BPF relocation checker                              : FAILED!

	I think these failures are not related to changes in this patch
kit. Details about the test environment, versions, etc.

Regards,

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 00/27] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, I'm now investigating why these failed:

  38: LLVM search and compile                               :
  38.1: Basic BPF llvm compile                              : Ok
  38.2: kbuild searching                                    : Ok
  38.3: Compile source for BPF prologue generation          : Ok
  38.4: Compile source for BPF relocation                   : FAILED!
  40: BPF filter                                            :
  40.1: Basic BPF filtering                                 : Ok
  40.2: BPF pinning                                         : Ok
  40.3: BPF prologue generation                             : Ok
  40.4: BPF relocation checker                              : FAILED!

	I think these failures are not related to changes in this patch
kit. Details about the test environment, versions, etc.

Regards,

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 00/27] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, I'm now investigating why these failed:

  38: LLVM search and compile                               :
  38.1: Basic BPF llvm compile                              : Ok
  38.2: kbuild searching                                    : Ok
  38.3: Compile source for BPF prologue generation          : Ok
  38.4: Compile source for BPF relocation                   : FAILED!
  40: BPF filter                                            :
  40.1: Basic BPF filtering                                 : Ok
  40.2: BPF pinning                                         : Ok
  40.3: BPF prologue generation                             : Ok
  40.4: BPF relocation checker                              : FAILED!

	I think these failures are not related to changes in this patch
kit. Details about the test environment, versions, etc.

Regards,

- Arnaldo

  perf test: Fix subtest number when showing results (2018-07-24 14:55:51 -0300)

----------------------------------------------------------------
perf/cores fixes and improvements:

Tools:

top:

- Fix 'struct comm_str' removal crash race, detected with refcount_t
  debugging (Jiri Olsa)

- Use last_match threads cache only in single threaded mode, fixing
  a crash (Jiri Olsa)

record:

- Synthesize GROUP_DESC feature in pipe mode fixing display of
  event groups (Jiri Olsa)

stat:

- Get rid of extra clock display function (Jiri Olsa)

perf script:

- Show correct offsets for DWARF-based unwinding (Sandipan Das)

test:

- Check that complex event name is parsed correctly (Alexey Budankov)

- Fix subtest number when showing results (Thomas Richter)

Arch specific:

arm64:

- Generate syscall table from the kernel sources (asm/unistd.h) like
  other arches do, speeding up the support for new system calls in
  tools such as 'perf trace' (Kim Phillips)

arm:

- Bail out immediatelly on CoreSight hardware tracing instruction sample failure (Leo Yan)

PowerPC:

- Fix record+probe_libc_inet_pton.sh 'perf test' entry (Sandipan Das)

- Callchain IP filtering fixes (Sandipan Das)

S/390:

- Add support for detailed S/390 PMU event description in 'perf list' (Thomas Richter)

- Add transaction flag (-T) support in 'perf stat' for S/390 (Thomas Richter)

- Fix 'perf kvm' S/390 subcommands (Thomas Richter)

Infrastructure:

hists:

- Clarify callchain disabling when available (Arnaldo Carvalho de Melo)

evsel:

- Use perf_evsel__match instead of open coded equivalent (Jiri Olsa)

Documentation:

- Add missing documentation for 'perf list' --desc and --debug options (Sangwon Hong)

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 00/27] 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 9128d3ed9de3882c83b927eb553d5d44c84505f5:

  perf/x86/msr: Clean up the code (2018-01-06 12:18:40 +0100)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.16-20180110

for you to fetch changes up to 5d64db2966e38bfd99114ecf0b54f97d33023dcd:

  tools headers: Synchronize kernel <-> tooling headers (2018-01-10 12:46:54 -0300)

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

- The 'perf test bpf' entry hooked a eBPF proggie to the
  SyS_epoll_wait() kernel function and expected it to be hit when calling
  the epoll_wait() libc wrapper, which changed recently, in systems such
  as Fedora 27, with the glibc wrapper calling instead the epoll_pwait()
  syscall, so switch to epoll_pwait() for both the kernel and libc
  function, getting it to work both in old and new systems (Arnaldo Carvalho de Melo)

- Beautify 'gettid' syscall result in 'perf trace', and in doing so
  noticed that we need to handle namespaces in 'perf trace', will be
  dealt with in follow up patches where we'll try to figure out if
  the recent support for namespace in tools/perf/ can be used for this
  purpose as well. (Arnaldo Carvalho de Melo)

- Introduce 'perf report --mmaps' and 'perf report --tasks' to show
  info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)

- Synchronize kernel <-> tooling headers wrt meltdown/spectre changes
  (Arnaldo Carvalho de Melo)

- Fix a wrong offset issue when using /proc/kcore (Jin Yao)

- Fix bug that prevented annotating symbols in perf.data files
  generated with 'perf record --branch-any'  (Jin Yao)

- Add infrastructure to record first and last sample time to the
  perf.data file header, so that when processing all samples in
  a 'perf record' session, such as when doing build-id processing,
  or when specifically requesting that that info be recorded, use
  that in 'perf report --time', that also got support for percent
  slices in addition to absolute ones.

  I.e. now it is possible to ask for the samples in the 10%-20%
  time slice of a perf.data file (Jin Yao)

- Enable building with libbabeltrace by default (Jiri Olsa)

- Display perf_event_attr::namespaces when duping the attributes
  in verbose mode (Jiri Olsa)

- Allocate context task_ctx_data for child event (Jiri Olsa)

- Update comments for PERF_RECORD_ITRACE_START and PERF_RECORD_MISC_* (Jiri Olsa)

- Add support for showing PERF_RECORD_LOST events in 'perf script' (Jiri Olsa)

- Add 'perf report --stats' option to display quick statistics about
  metadata events (PERF_RECORD_*) i.e. what we get at the end of 'perf
  report -D' (Jiri Olsa)

- Fix compile error with libunwind x86 (Wang Nan)

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.

> 
> ----------------------------------------------------------------
> perf/core improvements and fixes:
> 
> - The 'perf test bpf' entry hooked a eBPF proggie to the
>   SyS_epoll_wait() kernel function and expected it to be hit when calling
>   the epoll_wait() libc wrapper, which changed recently, in systems such
>   as Fedora 27, with the glibc wrapper calling instead the epoll_pwait()
>   syscall, so switch to epoll_pwait() for both the kernel and libc
>   function, getting it to work both in old and new systems (Arnaldo Carvalho de Melo)
> 
> - Beautify 'gettid' syscall result in 'perf trace', and in doing so
>   noticed that we need to handle namespaces in 'perf trace', will be
>   dealt with in follow up patches where we'll try to figure out if
>   the recent support for namespace in tools/perf/ can be used for this
>   purpose as well. (Arnaldo Carvalho de Melo)
> 
> - Introduce 'perf report --mmaps' and 'perf report --tasks' to show
>   info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)
> 
> - Synchronize kernel <-> tooling headers wrt meltdown/spectre changes
>   (Arnaldo Carvalho de Melo)
> 
> - Fix a wrong offset issue when using /proc/kcore (Jin Yao)
> 
> - Fix bug that prevented annotating symbols in perf.data files
>   generated with 'perf record --branch-any'  (Jin Yao)
> 
> - Add infrastructure to record first and last sample time to the
>   perf.data file header, so that when processing all samples in
>   a 'perf record' session, such as when doing build-id processing,
>   or when specifically requesting that that info be recorded, use
>   that in 'perf report --time', that also got support for percent
>   slices in addition to absolute ones.
> 
>   I.e. now it is possible to ask for the samples in the 10%-20%
>   time slice of a perf.data file (Jin Yao)
> 
> - Enable building with libbabeltrace by default (Jiri Olsa)
> 
> - Display perf_event_attr::namespaces when duping the attributes
>   in verbose mode (Jiri Olsa)
> 
> - Allocate context task_ctx_data for child event (Jiri Olsa)
> 
> - Update comments for PERF_RECORD_ITRACE_START and PERF_RECORD_MISC_* (Jiri Olsa)
> 
> - Add support for showing PERF_RECORD_LOST events in 'perf script' (Jiri Olsa)
> 
> - Add 'perf report --stats' option to display quick statistics about
>   metadata events (PERF_RECORD_*) i.e. what we get at the end of 'perf
>   report -D' (Jiri Olsa)
> 
> - Fix compile error with libunwind x86 (Wang Nan)

o More prep work to support Intel PT: (Adrian Hunter)
  - Polishing 'script' BTS output
  - 'inject' can specify --kallsym
  - VDSO is per machine, not a global var
  - Expose data addr lookup functions previously private to 'script'
  - Large mmap fixes in events processing

o Fix build on gcc 4.4.7 (Arnaldo Carvalho de Melo)

o Event ordering fixes (Jiri Olsa)

o Include standard stringify macros in power pc code (Sukadev Bhattiprolu)
