* usually it's more important to know how much space will each package take on target device then size of compressed package * example for libewebkit0 with 4 different architectures, interesting that om_gta02 .ipk is bigger but it's smaller when installed before: MACHINE DEFAULTTUNE SIZE (.ipk file) om_gta04 cortexa8t-neon 15996 KiB libewebkit0 qemux86_64 x86-64 16992 KiB libewebkit0 spitz xscale 16148 KiB libewebkit0 om_gta02 arm920t 16260 KiB libewebkit0 after: MACHINE DEFAULTTUNE SIZE (installed) om_gta04 cortexa8t-neon 60544 KiB libewebkit0 qemux86_64 x86-64 63720 KiB libewebkit0 spitz xscale 60588 KiB libewebkit0 om_gta02 arm920t 56268 KiB libewebkit0 (From OE-Core rev: 85e4a77138381a6086d5ebd3a28cb5a94bc26a19) Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com> Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
