This script makes it easy to run a systemtap script on a remote target from a build host. The script itself contains documentation on basic setup and usage - see that for details. In a nutshell, if you have a systemtap script on the build host, this script allows that systemtap script to be compiled and run on the target host and for the output appear on the host terminal. The crosstap script requires to an sdk build of the target (or a build with 'tools-profile' added to EXTRA_IMAGE_FEATURES) because it needs to be able to run the native systemtap built by the systemtap recipe, which in turn needs access to the kernel built for the target in order to build the kernel modules that implement the systemtap probe specified by the systemtap script and which ultimately get shipped to the target and insmod'ed there. The crosstap script also needs to be able to ssh to the target host in order insert the modules on the target, so the target system needs to support incoming ssh connections.

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.
