      perf: change --root to --prefix for python install

      Otherwise we get the sysroot path appended to the build path, not what
      we want.

perf: fix the install-python_ext

2015-09-12T21:47:08+00:00

1. $(grep xxx xxx) never returns 0, it maybe return empty or string, and
can not compare with 0, this fixes that python module never are installed.

2. python library is installed into /usr/lib/ by default, but we expect
it is installed into ${libdir}, so add --install-lib parameter for python
setup.py to set the library dir;
this fixes not shipped warning, since python modules are installed into
/usr/lib/, but FILE_${PN}-python expects it is under ${libdir}, which is
/usr/lib64/ for 64bit machine

3. the makefile target install-python_ext is moved from Makefile to
Makefile.perf from linux v3.13, so match install-python_ext in Makefile.*
and --root='/\$(DESTDIR_SQ)' before linux v3.13 will install the target
python library to native sysroot, so replace it with --prefix as after linux
3.13;
this fixes not shipped warning, and install target files to native dir, like
below:

perf: fix build breakage on kernels after 4.1

2015-08-12T18:31:01+00:00

A recent commit fixed perf build failures with a change that duplicates
a fix that can be found in kernels after 4.1. Unfortunately there is a
conflict between these two fixes and we see perf build failures when
building perf in kernels that contain the fix already. The problem is
that the fix from the recipe modifies the location of .config-detected
to $(OUTPUT).config-detected. In a 4.2 kernel the location will be
changed to $(OUTPUT)$(OUTPUT).config-detected.

We change the recipe to require a space in the pattern to only change
kernel sources that do not already place file in $(OUTPUT).

The recent commit that introduced the build failure is:

   commit ea9016b60b47138bc58d84a06954b44527b20a19
    Author: Richard Purdie

        perf: Fix config file conflict with 4.1 kernels

        If you setup mutlitlibs and then:

        bitbake perf libb32-perf
        bitbake perf libb32-perf -c cleansstate
        bitbake perf libb32-perf

        you will see races where the two builds get confused about which directory
        they should be using and they corrupt each other.

        The issue is that .config-detected is created in ${S}, not $(OUTPUT).
        We can fix this by moving the file to $(OUTPUT).

perf: add liblzma depdenency

2015-07-31T14:35:36+00:00

With kernel commit 6c6f0f6164f [tools build: Add feature check for lzma
library], perf now performs a test for lzma and adds functionality
appropriately.

This currently is a floating dependency that will sometimes be present,
and sometimes not. The result is the following QA warning:

  WARNING: QA Issue: perf rdepends on liblzma, but it isn't a build dependency? [build-deps]

By adding xz to the DEPENDS, we'll ensure that it is consistently in
place.

perf: fix build (and feature tests) for 4.1-rcX

2015-05-03T10:39:47+00:00

The way that perf detects features has changed/moved via commit e6c76d620
[perf build: Move feature checks code under tools/build].

This code movement resulted in the definition of CC being dropped, and
in turn the passing of --sysroot not part of the build.

This results in feature tests failing with errors such as:

  In file included from test-pthread-attr-setaffinity-np.c:1:0:
  sysroots/x86_64-linux/usr/lib/x86_64-poky-linux/gcc/x86_64-poky-linux/4.9.2/include/stdint.h:9:26:
  fatal error: stdint.h: No such file or directory
  # include_next 
                          ^
  compilation terminated.

While the fix is going upstream, we can modify the perf recipe to add
the definition of CC into the Makefile, and we'll continue to work on
patched and unpatched kernels.

perf: add bash to RDEPENDS

perf has a dependency on bash in its utilities, which generate the
following warning:

  WARNING: QA Issue: perf requires /bin/bash, but no providers in its RDEPENDS [file-rdeps]

Since perf is not installed on extremely small systems, we just add
bash to the RDEPENDS, rather than modifying scripts or removing content.
