[GIT PULL 00/29] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

Please consider pulling, I had most of this queued before your first
pull req to Linus for 4.10, most are fixes, with 'perf sched timehist --idle'
as a followup new feature to the 'perf sched timehist' command introduced in
this window.

One other thing that delayed this was the samples/bpf/ switch to
tools/lib/bpf/ that involved fixing up merge clashes with net.git and also
to properly test it, after more rounds than antecipated, but all seems ok
now and would be good to get this merge issues past us ASAP.

  going to/from idle state (Namhyung Kim)

Fixes:

- Allow 'perf record -u user' to continue when facing races with threads
  going away after having scanned them via /proc (Jiri Olsa)

Infrastructure:

- Switch of samples/bpf/ to use tools/lib/bpf, removing libbpf
  duplication (Joe Stringer)

- Move headers check into bash script (Jiri Olsa)

Hi Ingo,

Please consider pulling, I had most of this queued before your first
pull req to Linus for 4.10, most are fixes, with 'perf sched timehist --idle'
as a followup new feature to the 'perf sched timehist' command introduced in
this window.

One other thing that delayed this was the samples/bpf/ switch to
tools/lib/bpf/ that involved fixing up merge clashes with net.git and also
to properly test it, after more rounds than antecipated, but all seems ok
now and would be good to get this merge issues past us ASAP.

  in the c2c tool (Jiri Olsa)

Documentation:

  Merge tag 'perf-core-for-mingo-3' of 
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core 
(2016-02-03 11:02:37 +0100)

  perf hists browser: Add 'L' hotkey to change percent limit (2016-02-03 
12:24:22 -0300)


perf/core improvements and fixes:

New features:

- Add 'L' hotkey to dynamicly set the percent threshold for histogram
  entries and callchains, i.e. dynamicly do what the --percent-limit
  command line option to 'top' and 'report' does. (Namhyung Kim)

Infrastructure:

- Per hists field and sort lists, that will be used, for instance,
  in the c2c tool (Jiri Olsa)

Documentation:

- Update documentation of --sort and --perf-limit options
  for 'perf report' (Namhyung Kim)

Hm, a 'make clean' cleaned up the condition and it now works as expected. 

So what happened is that GCC got upgraded from 4.8.1 to 4.8.2 and 
test-all.c failed to build:

  comet:~/tip/tools/perf/config/feature-checks> make -i
  make: *** No rule to make target 
`/usr/lib/gcc/x86_64-redhat-linux/4.8.1/include/limits.h', needed by 
`test-all'.  Stop.

but the individual testcases got built successfully and the perf build was 
fine and correct - it's just that the test-all.c .d file never got updated 
due to the broken dependency.

I think Namhyung warned about this during the feature-detection 
discussion, and I dismissed the concern - but Namhyung was right, it's a 
real problem.

I think to fix this we should automatically clean out potentially stale .d 
files automatically after testcase build failures (be it test-all.c or any 
other testcase)?

That would still preserve all the good roles of these dependencies and it 
would preserve the build speed and detection of system library changes.

Thanks,

Ingo

I guess this wanted to be perf-core-for-mingo?

perf/urgent fixes:

. Fix command line callchain attribute tests to handle the new
  -g/--call-chain semantics.

. Remove cast of non-variadic function to variadic, fixing perf output
  on armhf arch. Fix from Michael Hudson-Doyle.

. Fix 32-bit building of 'perf bench', from Wei Yang.

hm, probably one of these commits:

8a0c4c2843d3 perf tools: Fix libunwind build and feature detection for 32-bit 
build
28e962b9d79f perf tools: Fix 32-bit cross build
74af377bc25d perf tools: Fix non-debug build
9402802a416c perf tools: Fix test_on_exit for 32-bit build

broke the suppression of the auto-detection messages on repeat invocations 
of 'make', if all testcases pass.

'make' used to display this on repeat invocations:

 comet:~/tip/tools/perf make
   BUILD:   Doing 'make -j12' parallel build
 comet:~/tip/tools/perf make
   BUILD:   Doing 'make -j12' parallel build
 comet:~/tip/tools/perf make
   BUILD:   Doing 'make -j12' parallel build

Now it displays the spammy auto-detection all the time:

comet:~/tip/tools/perf make
  BUILD:   Doing 'make -j12' parallel build

Auto-detecting system features:
... backtrace: [ on  ]
... dwarf: [ on  ]
...fortify-source: [ on  ]
... glibc: [ on  ]
...  gtk2: [ on  ]
...  gtk2-infobar: [ on  ]

maybe a new testcase fails on my box, but is not properly displayed?
