Martin Jansa 6fa2d82978 perf: fix indentation
* multiline variables should use spaces not tabs for indentation
* do_configure is also using wrong indentation, but I'm not fixing
  this one (still hoping that we'll eventually fix styleguide to
  use 4 spaces everywhere)

Ting Liu 78a38c8ab2 perf: remove CFLAGS override
definition of __SANE_USERSPACE_TYPES__ was added in kernel source by
commit e3541ec75219819d3235f80125a1a75d798ff6e1
perf tools, powerpc: Fix compile warnings in tests/attr.c

Overriding the CFLAGS makes it impossible for kernel build system to
append to it, thus making the build fail in various ways as:

Richard Purdie ee4f52e279 perf: Fix sysroot option to CC handling
If you build perf in tree /xxx/treea, then cleansstate perf and build it
in /xxx/treeb having deleted treea, the build will fail, unable to find libc.

The problem is that the --sysroot option passed in through CC is missing.
This works fine if the default sysroot is ok, if it isn't, things will fail.
In 1.7 we'll start poisoning the default sysroot in gcc to catch this kind of
issue however that doesn't fix the problem with perf.

The problem is that various Makefiles set CC = $(CROSS_COMPILE)gcc. The
easist fix for now is to sed out the problematic Makefile lines. Its worth
noting the tools/lib/traceevent Makefile has a much more funky way of setting
CC which works for us and may be the way we need to fix the other Makefiles
upstream.

This fixes build failures we're occasionally seen on the autobuilders.

Bruce Ashfield 08808c9f40 perf: add libexec and traceevent to packages
Recent versions of perf may install files into /usr/libexec/perf-core and in
/usr/lib/traceevent. To avoid packaging QA errors, we add these two
directories to the FILES variables.

We also add: INHIBIT_PACKAGE_DEBUG_SPLIT="1" to avoid the following issue
(due to a trailing / being removed):

   ERROR: debugedit failed with exit code 256
   ...
   debugedit: canonicalization unexpectedly shrank by one character

And finally, we must ensure that the traceevent libraries are installed to
the proper multilib library path. If building some multlibs, the incorrect
library path will be selected by perf, since it triggers via: ifeq
($(ARCH),x86_64) (or similiar mechanism per arch).

In a 32 bit build, with a 64 bit multilib, the arch won't match and the
detection of a 64 bit build (and library) are not exected. To ensure that
libraries are installed to the correct location, we can make the substitution
in the config/Makefile. For non multilib builds, this has no impact.

'meta-metro' layer, revision 9d698004137c1a888d40d6a4808d94afa22387e7,
without any information about what problem it fixes so I am reverting
it.

There's nothing kernel-version-specific about the perf_3.4 recipe, so
it's actually misnamed and misleading now that it also gets used with

Since the recipe isn't tied to a specific PV, and simply uses
whatever's in STAGING_KERNEL_DIR, there's no reason to add anything
else either to the bare PN, so just use that as the recipe name.

Tom Zanussi b502bc282d perf: remove unconditional python-ext install
This shouldn't be unconditional - a later patch made it so, but that's
not yet pulled in.  In the meantime, to fix build failures remove the
unconditional install.

Tom Zanussi c964536dc9 perf: add libexec/perf-core and contents
libexec/perf-core contains all the pre-canned scripts and modules
needed by both the Perl and Python bindigs.  Add libexec/perf-core
along with all the pre-defined perf scripts underneath it.

Tom Zanussi d4eaa2d384 perf: enable Perl binding
Add support to enable the perf Perl binding.

The build depends on perl-native to retrieve the configuration
settings needed for the binding.  cpan-base adds some useful functions
like is_target() and get_perl_version() that we need for
PERLCONFIGTARGET and related settings, which allow us to use the
target's Config_heavy.pl settings for ExtUtils:Embed when building for
the target.

Also adds the perl-modules dependency to give the target the perl
modules that scripts using the binding need.

Tom Zanussi 7a2cf8682e perf: enable Python bindings
Add support to enable the perf python bindings.  The combination of
these changes and the changes in the python-config sections in the
kernel Makefile enable all the python bindings currently available in
perf.

Liang Li 6b9c19140c recipes-kernel: make perf a standalone package
perf has been coupled to the kernel packages via kernel.bbclass.
While maintaining the build of perf out of the kernel source tree
is desired the package coupling has proved to be awkward in
several situations such as:

  - when a kernel recipe doesn't want to build/provide perf
  - when licensing of dependencies would prohibit perf and hence
    the kernel from being built.

To solve some of these problems, this recipe is the extraction of
the linux-tools.inc provided perf compilation into a standalone
perf recipe that builds out of the kernel source, but is otherwise
independent.

No new functionality is provided above what the linux-tools.inc
variant provided, but the separate recipe provides baseline for
adding new functionality.
