This is a pretty fundamental change to the way bitbake operates. It splits out the task execution part of runqueue into a completely separately exec'd process called bitbake-worker. This means that the separate process has to build its own datastore and that configuration needs to be passed from the cooker over to the bitbake worker process. Known issues: * Hob is broken with this patch since it writes to the configuration and that configuration isn't preserved in bitbake-worker. * We create a worker for setscene, then a new worker for the main task execution. This is wasteful but shouldn't be hard to fix. * We probably send too much data over to bitbake-worker, need to see if we can streamline it. These are issues which will be followed up in subsequent patches. This patch sets the groundwork for the removal of the double bitbake execution for psuedo which will be in a follow on patch.

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 = "") 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, patches against the various components should be sent to their respective upstreams.
bitbake: bitbake-devel@lists.openembedded.org
meta-yocto: poky@yoctoproject.org
Most 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. 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.
