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

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

New features:

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

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

    $ trace -e file touch file

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

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

User visible fixes:

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

Documentation:

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

Infrastructure:

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

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

[PATCH 01/13] perf record: Document setting '-e pmu/period=N/' in man page

[Arnaldo Carvalho de Melo]

From: Kan Liang <kan.liang@intel.com>

The 'period' param is not defined in
/sys/bus/event_sources/devices/<pmu>/format/*, but can be used, document
it.

[PATCH 03/13] perf strlist: Make dupstr be the default and part of an extensible config parm

[Arnaldo Carvalho de Melo]

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

So that we can pass more info to strlist__new() without having to change
its function signature, just adding entries to the strlist_config struct
with sensible defaults for when those fields are not specified.

[PATCH 04/13] perf strlist: Allow substitutions from file contents in a given directory

[Arnaldo Carvalho de Melo]

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

So, if we have an strlist equal to:

   "file,close"

And we call it as:

   struct strlist_config *config = { .dirname = "~/strace/groups", };
   struct strlist *slist = strlist__new("file, close", &config);

And we have:
  $ cat ~/strace/groups/file
  access
  open
  openat
  statfs

Then the resulting strlist will have these contents:

  [ "access", "open", "openat", "statfs", "close" ]

This will be used to implement strace syscall groups in 'perf trace',
but can be used in some other tool, thus being implemented in 'strlist'.

[PATCH 06/13] perf trace: Support 'strace' syscall event groups

[Arnaldo Carvalho de Melo]

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

I.e.:

  $ cat ~/share/perf-core/strace/groups/file
  access
  chmod
  creat
  execve
  faccessat
  getcwd
  lstat
  mkdir
  open
  openat
  quotactl
  readlink
  rename
  rmdir
  stat
  statfs
  symlink
  unlink
  $

Then, on a quiet desktop, try running this and then moving your mouse to
see the deluge of mouse related activity:

  # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'
  Added new event:
    probe:vfs_getname    (on getname_flags:72 with pathname=filename:string)

  You can now use it in all perf tools, such as:

	perf record -e probe:vfs_getname -aR sleep 1
  #
  # trace --ev probe:vfs_getname --filter-pids 2232 -e file
   0.042 (0.042 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438                                   ) ...
   0.042 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/cursors/xterm")
   0.100 (0.100 ms): mousetweaks/2235  ... [continued]: open()) = -1 ENOENT No such file or directory
   0.142 (0.018 ms): mousetweaks/2235 open(filename: 0x14c3c10, mode: 438                                   ) ...
   0.142 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/index.theme")
   0.192 (0.069 ms): mousetweaks/2235  ... [continued]: open()) = -1 ENOENT No such file or directory
   0.230 (0.017 ms): mousetweaks/2235 open(filename: 0x14c3c10, mode: 438                                   ) ...
   0.230 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/usr/share/icons/Adwaita/cursors/xterm")
   0.253 (0.041 ms): mousetweaks/2235  ... [continued]: open()) = 14
   0.459 (0.008 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438                                   ) ...
   0.459 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/cursors/left_side")
   0.468 (0.017 ms): mousetweaks/2235  ... [continued]: open()) = -1 ENOENT No such file or directory

Need to combine that raw_syscalls:sys_enter(open) + probe:vfs_getname +
raw_syscalls:sys_exit(open) sequence...

Now, if you're bored, please write some more syscall groups, like the ones
in 'strace' and send it our way :-)

[PATCH 07/13] perf record: Apply filter to all events in a glob matching

[Arnaldo Carvalho de Melo]

From: Wang Nan <wangnan0@huawei.com>

There is an old problem in perf's filter applying which first posted at
Sep. 2014 at https://lkml.org/lkml/2014/9/9/944 that, if passing
multiple events in a glob matching expression in cmdline then add
'--filter' after them, the filter will be applied on only the last one.

For example:

 # dd if=/dev/zero of=/dev/null &
 [1] 464
 # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' sleep 0.1
 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.239 MB perf.data (2094 samples) ]
 # perf report --stdio | tee
 ...
 # Samples: 2K of event 'syscalls:sys_enter_read'
 # Event count (approx.): 2092
 ...
 # Samples: 2  of event 'syscalls:sys_exit_read'
 # Event count (approx.): 2
 ...

In this example, filter only applied on 'syscalls:sys_exit_read', and
there's no way to set filter for ''syscalls:sys_enter_read'.

This patch adds a 'cmdline_group_boundary' for 'struct evsel', and
apply filter on all events between two boundary marks.

After applying this patch:

 # perf record -a -e 'syscalls:sys_*_read' --filter 'common_pid != 464' sleep 0.1
 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.031 MB perf.data (3 samples) ]
 # perf report --stdio | tee
 ...
 # Samples: 1  of event 'syscalls:sys_enter_read'
 # Event count (approx.): 1
 ...
 # Samples: 2  of event 'syscalls:sys_exit_read'
 # Event count (approx.): 2
 ...

[PATCH 08/13] perf record: Allow filtering perf's pid via --exclude-perf

[Arnaldo Carvalho de Melo]

From: Wang Nan <wangnan0@huawei.com>

This patch allows 'perf record' to exclude events issued by perf itself
by '--exclude-perf' option.

Before this patch, when doing something like:

 # perf record -a -e syscalls:sys_enter_write <cmd>

One could easily get result like this:

 # /tmp/perf report --stdio
 ...
  # Overhead  Command  Shared Object       Symbol
  # ........  .......  ..................  ....................
  #
      99.99%  perf     libpthread-2.18.so  [.] __write_nocancel
      0.01%   ls       libc-2.18.so        [.] write
      0.01%   sshd     libc-2.18.so        [.] write
 ...

Where most events are generated by perf itself.

A shell trick can be done to filter perf itself out:

 # cat << EOF > ./tmp
 > #!/bin/sh
 > exec perf record -e ... --filter="common_pid != \$\$" -a sleep 10
 > EOF
 # chmod a+x ./tmp
 # ./tmp

However, doing so is user unfriendly.

This patch extracts evsel iteration framework introduced by patch 'perf
record: Apply filter to all events in a glob matching' into
foreach_evsel_in_last_glob(), and makes exclude_perf() function append
new filter expression to each evsel selected by a '-e' selector.

To avoid losing filters if user pass '--filter' after '--exclude-perf',
this patch uses perf_evsel__append_filter() in both case, instead of
perf_evsel__set_filter() which removes old filter. As a side effect, now
it is possible to use multiple '--filter' option for one selector. They
are combinded with '&&'.

[PATCH 13/13] perf bench futex: Add lock_pi stresser

[Arnaldo Carvalho de Melo]

From: Davidlohr Bueso <dave@stgolabs.net>

Allows a way of measuring low level kernel implementation of FUTEX_LOCK_PI and
FUTEX_UNLOCK_PI.

The program comes in two flavors:

(i) single futex (default), all threads contend on the same uaddr.  For the
sake of the benchmark, we call into kernel space even when the lock is
uncontended.  The kernel will set it to TID, any waters that come in and
contend for the pi futex will be handled respectively by the kernel.

(ii) -M option for multiple futexes, each thread deals with its own futex. This
is a trivial scenario and only measures kernel handling of 0->TID transition.

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

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo

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

The following changes since commit 7f16023bfcc4b1f2bbccf86219dc97473db6e0d6:

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

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

perf test:

- Add watchpoint entry (Ravi Bangoria)

Build fixes:

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

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

Hardware tracing:

- Suppress AUX/OVERWRITE records (Alexander Shishkin)

Infrastructure:

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

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

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

 create mode 100644 tools/perf/tests/wp.c

Test results:

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

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

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

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

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

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

perf/core improvements and fixes:

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

  e.g.:

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.

  perf annotate browser: Circulate percent, total-period and nr-samples view (2017-08-18 11:23:20 -0300)

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

- Support --show-nr-samples in annotate's --stdio and --tui, using
  the existing 't' toggle to circulate 'percent', 'total-period' and
  'nr-samples' as the first column (Taeung Song)

- Support FCMask and PortMask in JSON vendor events (Andi Kleen)

- Fix off by one string allocation problem in 'perf trace' (Arnaldo Carvalho de Melo)

- Use just one parse events state struct in yyparse(), fixing one
  reported segfault when a routine received a different data struct,
  smaller than the one it expected to use (Arnaldo Carvalho de Melo)

- Remove unused cpu_relax() macros, they stopped being used when
  tools/perf lived in Documentation/ (Arnaldo Carvalho de Melo)

- Fix double file test in libbpf's Makefile (Daniel Díaz):

Test results:

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

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

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

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

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

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

Test results:

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

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

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

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

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

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

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

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

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo

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

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

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

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

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

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

The following changes since commit ad5013d5699d30ded0cdbbc68b93b2aa28222c6e:

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

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

New features:

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

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

       perf record -a --switch-output=signal

  is equivalent to what we had before:

       perf record -a --switch-output

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

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

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

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

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

  (Jiri Olsa)

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

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

  or:

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

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

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

  E.g:

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

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

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

- Intel PT timestamp fixes (Adrian Hunter)

- Fix Intel JSON fixed counter conversions (Andi Kleen)

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

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

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

- Fix uretprobe probe placement on ppc64le (Ravi Bangoria)

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

  perf buildid-cache: Use lsdir() for looking up buildid caches (2016-05-11 13:06:08 -0300)

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

User visible:

- Fix symbol insertion and callchain behavior in db-export (Chris Phlipot)

Infrastructure:

- Add libunwind build test (feature query), working towards supporting
  cross-platform DWARF callchains, starting with arm/arm64 (He Kuang)

- Use lsdir() more extensively (Masami Hiramatsu)

- Use SBUILD_ID_SIZE in places where the equivalent expression was
  being used (Masami Hiramatsu)

- Split some more 'perf trace' syscall arg beautifiers (Arnaldo Carvalho de Melo)

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

----------------------------------------------------------------
Arnaldo Carvalho de Melo (3):
      perf scripting python: Use Py_FatalError instead of die()
      perf trace: Move flock op beautifier to tools/perf/trace/beauty/
      perf trace: Move seccomp args beautifiers to tools/perf/trace/beauty/

Chris Phlipot (4):
      perf symbols: Add dso__insert_symbol function
      perf script: Fix symbol insertion behavior in db-export
      perf script: Fix callchain addresses in db-export
      perf script: Fix export of callchains with recursion in db-export

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

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

User visible:

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

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

Infrastructure:

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

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

Cleanups:

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

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

      bpf tools: Remove expression with no effect
      bpf tools: Fix syscall argument

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

- Do not show sample_(type|period) in the perf_event_attr dump when using
  -v with 'perf stat' (Jiri Olsa)

  when --hide-unresolved gets supported in that tool (Namhyung Kim)

- Fix freeze wit h--call-graph 'flat/folded' due to not properly
  reinitializing the callchain rb_tree (Namhyumg Kim)

- Set dso->long_name when a module name is passed as a parameter

  still doesn't have the full path for the module, just the '[name]' one
  obtained from /proc/modules (Wang Nan)

Infrastructure:

- Add helper function for updating bpf maps elements (He Kuang)

Hi Ingo,

	Please consider applying,

The following changes since commit 5f1230c9b80b89f404938ff88dfa64a963f74f2c:

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

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

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

User visible:

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

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

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

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

Infrastructure fixes:

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

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

Pulled, thanks a lot Arnaldo!

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

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

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

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

Thanks,

	Ingo

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

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

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

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

64-bit executables work fine:

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

      Total time: 13.374 [sec]

 [ perf record: Woken up 14 times to write data ]
 [ perf record: Captured and wrote 3.602 MB perf.data (~157354 samples) ]

The kernel is an older one:

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

We are not relying on it in the sense the 'record' works without it.
There is more explanation in "perf tools: Build programs to copy 32-bit

another email about that in a moment).

I did 'make install' as usual - that's the only thing that I type 
to install a new version of perf tooling.

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

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

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

	patchwork:

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

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

The originals were changed as described here:

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

Yeah, that's perfectly OK.

I pulled it locally then unpulled as it didn't pass my (very 
simple) tests and it looked like there's something fishy going 
on.

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

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

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

Something like this might prevent Ingo's error message:


From: Adrian Hunter <adrian.hunter@intel.com>
Date: Wed, 10 Sep 2014 16:14:50 +0300
Subject: [PATCH] perf tools: Do not attempt to run perf-read-vdso32 if it
 wasn't built

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

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

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

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

Refactorings:

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

Developer stuff:

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

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

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