[PATCH 0/5] kernel: consolidated pull request (linux-yocto-4.1 and perf)

[PATCH 0/5] kernel: consolidated pull request (linux-yocto-4.1 and perf)

[Bruce Ashfield]

Hi all,

In this series I have two sets of backports, and one configuration change to
linux-yocto.

The config change addresses YOCTO 9269, and is as follows:

  [PATCH 1/5] linux-yocto: ktypes/standard: Add tmpfs-posix-acl feature]

    This enables the CONFIG_TMPFS_POSIX_ACL, which is wanted by things like
    systemd. We also explicitly enable the features's dependencies and
    options selected by the feature for clarity.

The backports are mainline cherry-picks, and have built safely on a number of
boards ofr me.

  [PATCH 2/5] linux-yocto/4.1: device property : Backport device property patches
  [PATCH 3/5] linux-yocto/4.1: MFD backports

The two perf fixes are addressing some issues with the python scripts that perf
ships. They were either runtime broken (missing modules), or were generating
QA warnings. These address [YOCTO #8991] and [YOCTO #9069].

I've executed the python scripts on target, and everything looks sane!

Cheers,

Bruce

[PATCH 4/5] perf: fix python scripts QA errors

[Bruce Ashfield]

Two QA warnings were being generated from perf, due to the location of
python scripts changing in the kernel build:

WARNING: perf-1.0-r9 do_package_qa: QA Issue:
  /usr/libexec/perf-core/scripts/python/call-graph-from-postgresql.py contained
  in package perf-python requires /usr/bin/python2, but no providers found in RDEPENDS_perf-python? [file-rdeps]

WARNING: QA Issue: /usr/libexec/perf-core/tests/attr.py_perf contained in package
  perf requires /usr/bin/python, but no providers found in its RDEPENDS [file-rdeps]

By adding libexec dir to both the tests and scripts packaging, we get the
appropriate RDEPENDS on the packages that actually contain the python scripts
(without making perf-core depend on python).

We also tweak any python scripts to use '/usr/bin/env python', rather than a
version specific python, since it won't be provided and generate a QA error.

[PATCH 5/5] perf: package python modules into perf-python

[Bruce Ashfield]

The scripts that are part of perf require python and supporting modules.
The existing perf-pyton dependency only brought in core python, which
left us unable to actually execute the scripts on target.

With this additional runtime dependency, we can now execte the sample
analysis scripts when perf-scripting is availble.

This is a partial fix for [YOCTO #9069], since there are still scripts
looking for non-existent modules, and those will be dealt with in
future releases.
