  perf test shell: Replace '|&' with '2>&1 |' to work with more shells 
(2017-08-16 16:23:26 -0300)


perf core improvements and fixes:

New features:

- Support exporting Intel PT data to sqlite3 with python perf scripts,
  this is in addition to the postgresql support that was already there (Adrian 
Hunter)

Infrastructure:

- Handle perf tool builds with less features in perf shell tests, such
  as those with NO_LIBDWARF=1 or even without 'perf probe' (Arnaldo Carvalho de 
Melo)

- Replace '|&' with '2>&1 |' to work with more shells in the just
  introduced perf test shell harness (Kim Phillips)

Architecture related fixes:

- Fix endianness problem when loading parameters in the BPF prologue
  generated by perf, noticed using 'perf test BPF' in s390x systems (Wang Nan, 
Thomas Richter)

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

  perf config: Refactor a duplicated code for obtaining config file name 
(2017-05-02 18:23:12 -0300)


perf/core improvements and fixes:

Fixes:

- Support setting probes in versioned user space symbols, such as
  pthread_create@@GLIBC_2.1, picking the default one, more work
  needed to make it possible to set it on the other versions, as
  the 'perf probe' syntax already uses @ for other purposes.
  (Paul Clarke)

- Do not special case address zero as an error for routines that
  return addresses (symbol lookup), instead use the return as the
  success/error indication and pass a pointer to return the address,
  fixing 'perf test vmlinux' (the one that compares address between
  vmlinux and kallsyms) on s/390, where the '_text' address is equal
  to zero (Arnaldo Carvalho de Melo)

Infrastructure:

- More header sanitization, moving stuff out of util.h into
  more appropriate headers and objects and sometimes creating
  new ones (Arnaldo Carvalho de Melo)

- Refactor a duplicated code for obtaining config file name (Taeung Song)

Signed-off-by: Arnaldo Carvalho de Melo 


Arnaldo Carvalho de Melo (8):
  perf buildid: Move prototypes from util.h to build-id.h
  perf tools: Move event prototypes from util.h to event.h
  perf memswap: Split the byteswap memory range wrappers from util.[ch]
  perf tools: Move HAS_BOOL define to where perl headers are used

New feature:

- Account thread wait time (off cpu time) separately: sleep, iowait and
  preempt, based on the prev_state of the last event, show the breakdown
  when using "perf sched timehist --state" (Namhyumg Kim)

- Remove unnecessary feature-dwarf warning (David Carrillo-Cisneros)

- Add missing member name in OPT_() macros (Soramichi AKIYAMA)

- Move variables referenced in libperf.a object files from perf's main()
  file, so that other tools can use libperf.a with a different main()

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.

Yeah, agreed, its short, and it provides the output ready to be used, no
need for extra processing, up to the user to decide if one or the other
is more suitable to their needs.

As a bonus, it documents callgraphs in scripts, good deal :-)

Yes, the idea for stackcollapse-perf.py was:

- to do everything directly and emit "the right" format for the
flamegraph tools.  This however is a very minimal output, and it's not
necessarily the best for perf in general.

- to provide an example of visiting callgraphs from the scripting
interface, since it's not really documented.  From the commit message:
"Add stackcollapse.py script as an example of parsing call chains, and
also of using optparse to access command line options".

Pretty much. Two similar solutions were developed around the same
time. Although I have to use some awk to get "perf -g folded" in the
exact right format, and stackcollapse-perf.py does that directly.

[GIT PULL 00/10] perf/core improvements and fixes

Hi Ingo,

Please consider pulling,

The following changes since commit 275ae411e56f8f900fa364da29c4706f9af4e1f3:

  perf/x86/intel/rapl: Fix pmus free during cleanup (2016-05-25 10:56:43 +0200)

  tools: Pass arg to fdarray__filter's call back function (2016-05-25 17:27:25 
-0300)


perf/core improvements and fixes:

User visible/kernel ABI:

- Per event callchain limit: Recently we introduced a sysctl to tune the
  max-stack for all events for which callchains were requested:

  $ sysctl kernel.perf_event_max_stack
  kernel.perf_event_max_stack = 127

  Now this patch introduces a way to configure this per event, i.e. this
  becomes possible:

  $ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a

  allowing finer tuning of how much buffer space callchains use.

  This uses an u16 from the reserved space at the end, leaving another
  u16 for future use.

  There has been interest in even finer tuning, namely to control the
  max stack for kernel and userspace callchains separately. Further
  discussion is needed, we may for instance use the remaining u16 for
  that and when it is present, assume that the sample_max_stack introduced
  in this patch applies for the kernel, and the u16 left is used for
  limiting the userspace callchain. (Arnaldo Carvalho de Melo)

- Fix kptr_restrict=2 related 'perf record' segfault (Wang Nan)

Infrastructure;

- Adopt get_main_thread from db-export.c (Andi Kleen)

- More prep work for backward ring buffer support (Wang Nan)

Arnaldo Carvalho de Melo (2):

Wang Nan (7):
  perf symbols: Check kptr_restrict for root

Hi Ingo,

The following changes since commit fe7a2eaa71c55aadbf95d01d32df8dccc0db0646:

  Merge tag 'perf-core-for-mingo' of

  perf stat: Move noise/running printing into printout (2016-02-16 17:13:02 
-0300)


perf/core improvements and fixes:

User visible:

- Make 'perf record' collect CPU cache info in the perf.data file header:

  $ perf record usleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.017 MB perf.data (7 samples) ]
  $ perf report --header-only -I | tail -10 | head -8
  # CPU cache info:
  #  L1 Data 32K [0-1]
  #  L1 Instruction  32K [0-1]
  #  L1 Data 32K [2-3]
  #  L1 Instruction  32K [2-3]
  #  L2 Unified 256K [0-1]
  #  L2 Unified 256K [2-3]
  #  L3 Unified4096K [0-3]
  $

  Will be used in 'perf c2c' and eventually in 'perf diff' to allow, for 
instance
  running the same workload in multiple machines and then when using 'diff' show
  the hardware difference. (Jiri Olsa)

- 'perf stat' now shows shadow metrics (insn per cycle, etc) in
  interval mode too. E.g:

# perf stat -I 1000 -e instructions,cycles sleep 1
# time   counts unit events
   1.000215928  519,620  instructions #  0.69 insn per cycle
   1.000215928  752,003  cycles


Infrastructure:

- libapi now can also use pr_{warning,info,debug}() and that can be
  set by tools using it (Jiri Olsa)

- libapi adopts filename__read_str() from perf, adds sysfs__read_str() (Jiri 
Olsa)

- Add check for java alternatives cmd in jvmti Makefile, so that it manages
  to automatically find the right path for the JDK devel files in Ubuntu like
  systems in addition to Fedora like ones (Stephane Eranian)

At least my changes should go into perf/urgent and probably stable too.

Pulled, thanks a lot Arnaldo!

Should any of the above fixes be cherry-picked over into perf/urgent, or are 
these 
all new regressions?

Thanks,

Hm, your pull request mail was cut short as it ends here abruptly. I figured it 
out nevertheless, from the commit log:

>

User visible changes:

  - Force period term to overload global settings, i.e. previously this
command line:

 $ perf record -e 'cpu/instructions,period=2/',cycles -c 1000 sleep 1

would result in both events having a period equal to 1000, with the fix we
get something saner:

 $ perf evlist -v | grep period
 cpu/instructions,period=2/: ... { sample_period, sample_freq }: 2, 
...
 cycles: ... { sample_period, sample_freq }: 1000 ...
 $

   (Jiri Olsa)

Infrastructure changes:

  - Use the dummy software event with freq=0 in the twatch.py python
binding example, to avoid disabling nohz. (Arnaldo Carvalho de Melo)

  - Add some missing constants to the python binding. (Arnaldo Carvalho de Melo)

  - Fix mismatched declarations for elf_getphdrnum, that happens
only in the corner case where this function is not found on
the system.  (Arnaldo Carvalho de Melo)

  - Add build test for having ending double slash. (Jiri Olsa)

  - Introduce callgraph_set for callgraph option. (Kan Liang)

So a bit of background: sloppy, abusive contributors not willing to 
change get ignored after some time. For example Andi got such a bad 
track record in the x86 and perf space with me that all your mails go 
to /dev/null currently. (I only saw this one because Namhyung replied 
to it.)

Andi, as I explained it to you previously, if you want me to merge 
patches from you then you need to 1) improve the way you work 2) send 
it to someone who is willing to deal with you and sign off on it and 
forward it to me.

Seems like you managed to burn up your goodwill with Arnaldo as well. 
You need to find someone else willing to pay the expense of dealing 
with your passive-aggressive style.

Just a quick example of your abuse: for example you know it perfectly 
well that perf is well maintained, a simple 'git log tools/perf/' will 
tell you that there's a steady stream of patches going in and that 
perf contributors are busy.

Yet in this mail you actually lie about that: you pretend that you 
don't know that most Linux maintainers have trouble working with you, 
you pretend that perf is "unmaintained", you pretend that you don't 
know who is maintaining it, just to create unfair pressure on Arnaldo 
...

That kind of approach really sucks, and if you run out of people's 
patience with petty office tactics like that then you should not fault 
them, you should fault yourself.

Thanks,

Ingo

  perf trace: Tell arg formatters the arg index (2013-09-02 16:40:40 -0300)


perf/core improvements and fixes:

. 'perf trace' arg formatting improvements to allow masking arguments
  in syscalls such as futex and open, where the some arguments are
  ignored and thus should not be printed depending on other args.

. Beautify futex open, openat, open_by_handle_at, lseek and futex syscalls.

. Add dummy software event to use when wanting just to keep receiving
  PERF_RECORD_{MMAP,COMM,etc}, add test for it, from Adrian Hunter.

. Fix symbol offset computation for some dsos in 'perf script', from David 
Ahern.

. Skip unsupported hardware events in 'perf list', from Namhyung Kim.
