perf has been coupled to the kernel packages via kernel.bbclass.
While maintaining the build of perf out of the kernel source tree
is desired the package coupling has proved to be awkward in
several situations such as:
- when a kernel recipe doesn't want to build/provide perf
- when licensing of dependencies would prohibit perf and hence
the kernel from being built.
To solve some of these problems, this recipe is the extraction of
the linux-tools.inc provided perf compilation into a standalone
perf recipe that builds out of the kernel source, but is otherwise
independent.
No new functionality is provided above what the linux-tools.inc
variant provided, but the separate recipe provides baseline for
adding new functionality.

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.
