I forgot to push perf/core, having pushed just
perf-core-for-mingo-20160607, which is enough for Ingo to pull what I
sent to him, but not for you to get if you use perf/core, as usual,
instead of perf-core-for-mingo-20160607.

I pushed perf/core now, please update your local repo and all should be
ok now.

Re: [GIT PULL 00/24] perf/core improvements and fixes

Hi, Arnaldo

I found something weird about perf/core branch on your repository.
(I don't know whether it is just my illusion or not)

I can't pull new commits on top of perf-core-for-mingo-20160606
by normal way as below


# git remote show acme
* remote acme
  Fetch URL: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git


# git log --oneline
edb13ed tools lib bpf: Rename set_private() to set_priv()
be834ff tools lib bpf: Make bpf_program__get_private() use IS_ERR()
...


# git pull acme perf/core
From git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
 * branchperf/core  -> FETCH_HEAD
Already up-to-date.


And then nothing changed, I didn't also find new commits
and new tag 'perf-core-for-mingo-20160607'.

However, if using tag perf-core-for-mingo-20160607,
I can get new commits from your repository as below.

perf/core improvements and fixes:

User visible:

- Support cross unwinding, i.e. collecting '--call-graph dwarf' perf.data files
   in one machine and then doing analysis in another machine of a different
   hardware architecture. This enables, for instance, to do:

perf record -a --call-graph dwarf

   on a x86-32 or aarch64 system and then do 'perf report' on it on a
   x86_64 workstation. (He Kuang)

- Fix crash in build_id_cache__kallsyms_path(), recent regression (Wang Nan)

Infrastructure:

- Make tools/lib/bpf use the IS_ERR return facility consistently and also stop
   using the _get_ term for non-reference count methods (Arnaldo Carvalho de 
Melo)

- 'perf config' refactorings (Taeung Song)

   perf callchain: Support aarch64 cross-platform (2016-06-07 15:13:35 -0300)


perf/core improvements and fixes:

User visible:

- Support cross unwinding, i.e. collecting '--call-graph dwarf' perf.data files
   in one machine and then doing analysis in another machine of a different
   hardware architecture. This enables, for instance, to do:

perf record -a --call-graph dwarf

   on a x86-32 or aarch64 system and then do 'perf report' on it on a
   x86_64 workstation. (He Kuang)

- Fix crash in build_id_cache__kallsyms_path(), recent regression (Wang Nan)

Infrastructure:

- Make tools/lib/bpf use the IS_ERR return facility consistently and also stop
   using the _get_ term for non-reference count methods (Arnaldo Carvalho de 
Melo)

- 'perf config' refactorings (Taeung Song)

Signed-off-by: Arnaldo Carvalho de Melo 


Arnaldo Carvalho de Melo (7):
   tools lib bpf: Use IS_ERR() reporting macros with bpf_map__get_private()
   tools lib bpf: Rename bpf_map__get_name() to bpf_map__name()
   tools lib bpf: Use IS_ERR() reporting macros with bpf_map__get_def()
   tools lib bpf: Rename bpf_map__get_fd() to bpf_map__fd()
   tools lib bpf: Remove _get_ from non-refcount method names
   tools lib bpf: Make bpf_program__get_private() use IS_ERR()
   tools lib bpf: Rename set_private() to set_priv()

He Kuang (14):
   perf unwind: Use LIBUNWIND_DIR for remote libunwind feature check
   perf unwind: Decouple thread->address_space on libunwind
   perf unwind: Introduce 'struct unwind_libunwind_ops' for local unwind
   perf unwind: Move unwind__prepare_access from thread_new into 
thread__insert_map
   perf unwind: Don't mix LIBUNWIND_LIBS into LIBUNWIND_LDFLAGS
   perf unwind: Separate local/remote libunwind config
   perf unwind: Rename unwind-libunwind.c to unwind-libunwind-local.c
   perf tools: Extract common API out of unwind-libunwind-local.c
   perf tools: Export normalize_arch() function

the patch that moves babeltrace out of default
check wasn't pulled in yet:

http://marc.info/?l=linux-kernel=142606453815125=2

also note there's another bug in test-all that prevents
the test-all speed up, fixed by this patch:

http://marc.info/?l=linux-kernel=142606452415123=2

I think we should have the possibility to work and commit new
features even if the support is not yet in the main distros

for such features we could:
  - leave those features out of the default features check
like we'll do for babeltrace
  - maybe use some sort of EXPERIMENTAL config option dependency
once we have the .config file support ;-)

So this still doesn't seem to work for me:

... libbabeltrace: [ OFF ]

it should really not be included in the default build until the 
required library features are more widely available in distros.

I think we should only use library features by default that are 
available in the latest Fedora, SuSE and Ubuntu distros. We want them 
to build and package perf and there's little point in adding features 
that won't work on packaged up perf.

Thanks,

 One minor observation, the Makefile tells us:
 
 Makefile:496: No libunwind found. Please install libunwind = 0.99
 
 I guess that should be libunwind-dev[el], right? Plain libunwind 
 is not enough.

right, will fix it
