 The following changes since commit 5f1230c9b80b89f404938ff88dfa64a963f74f2c:
 
   Merge tag 'perf-core-for-mingo' of

 (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)

 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:

   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

 - 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

Agreed, some more work is needed to change that message in more places,

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.

Subject: [PATCH] perf tools: Do not attempt to run perf-read-vdso32 if it

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.

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

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

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 :-\

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.

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

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?

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/4729131/
https://patchwork.kernel.org/patch/4729111/

marc.info:

http://marc.info/?l=linux-kernel=140812995414607=4
http://marc.info/?l=linux-kernel=140812993814585=4

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

The originals were changed as described here:

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
compatibility VDSOs" and "perf tools: Add support for 32-bit compatibility
VDSOs" (although those are the wrong versions of those patches - I will send
another email about that in a moment).

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
compatibility VDSOs and perf tools: Add support for 32-bit compatibility
VDSOs (although those are the wrong versions of those patches - I will send
another email about that in a moment).

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

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

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

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

Thanks,

I pulled it locally then unpulled as it didn't pass my (very

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 :-\

 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

Ok, those don't apply, as it expects other stuff, that you sent before,

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) ]

/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 100 pipe operations between two processes

  Total time: 13.374 [sec]

 [ perf record: Captured and wrote 3.602 MB perf.data (~157354 samples) ]

The kernel is an older one:

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 100 pipe operations between two processes

  Total time: 13.374 [sec]

   13.374352 usecs/op
   74769 ops/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:

 $ uname -a
 Linux comet 3.14.17-100.fc19.x86_64 #1 SMP Thu Aug 14 17:17:26 
 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Thanks,

Ingo
