The current codeparser cache handling hurts performance badly even over a couple of cores and certainly on many core systems, it can spent huge amounts of time in the codeparser cache save functions. This patch reworks the cache handling so that each parsing thread saves out its own "differences" file compared to any existing core cache and then the main bitbake thread picks these up and merges things back together. This was tested on systems with small and large numbers of cores and was found to perform orders of magnitude better in all cases despite the more complex code.

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/community/documentation
