Lernel meta-data that has patches, but no branches, can trigger an error due to no branch specific patch queue. This error then cascades to more issues since the tools are using a named file in /tmp to store and display error messages to the user. We fix both issues though the following kern tools tweaks: commit bd9e1d6c9b0a34ff3e19a06999aaf57ffadfd04c Author: Bruce Ashfield <bruce.ashfield@windriver.com> Date: Fri Dec 2 13:09:40 2016 -0500 scc: use mktemp for consolidated output capture To provide useful error messages the tools dump pre-processed files and messages to a temporary file. If multiple users are doing builds, this means they either race, or can have permissions issues. By creating the temporary file via mktemp, we avoid both issues. (We also make sure to clean these up on exit, or /tmp will get polluted quickly). commit a287da4bfe0b4acb8f2b0627bd8e7abd1a1dde26 Author: Bruce Ashfield <bruce.ashfield@windriver.com> Date: Fri Dec 2 13:08:08 2016 -0500 patch: do not assume a branch specific patch queue is needed When processing input files per-branch and global patch queues are generated. If the meta-data has not created any branches in the repo, no branch specific queue is required. The tools assumed that one is always valid, and hence would throw a non-zero exit code and stop processing. By testing for a named per-branch queue, we avoid this issue.

Poky
Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
Everything else should be sent to the OpenEmbedded Core mailing list. If in doubt, check the oe-core git repository for the content you intend to modify. Before sending, be sure the patches apply cleanly to the current oe-core git repository.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of oe-core and poky-specific files.
