There seems to be little advantage to letting distro features affect native builds. There is a significant disadvantage: a change to DISTRO_FEATURES will trigger a lot of unnecessary native tasks. In a test like this: $ bitbake core-image-minimal # append " systemd" to DISTRO_FEATURES $ bitbake core-image-minimal The latter build takes 44 minutes (28%) of cpu-time less with this patch (skipping 135 native tasks). Sadly wall clock time was not affected as glibc remains the bottleneck. Set native distro features to DISTRO_FEATURES_NATIVE appended with an intersection of DISTRO_FEATURES and DISTRO_FEATURES_FILTER_NATIVE. Current default values (baitbake.conf) are * DISTRO_FEATURES_FILTER_NATIVE ?= "api-documentation" (as gtk-doc-native has much less dependencies when built without it) * DISTRO_FEATURES_NATIVE ?= "x11" (to enable native UIs even if target does not containe them) Do the variable setting in native_virtclass_handler() because otherwise it could still be overridden by appends and the feature backfilling. Shuffle the early returns so DISTRO_FEATURES gets set as long as the packagename ends with "-native". Add similar variables for nativesdk. To make nativesdk work we need to enable the locale options so nativesdk-glibc-locales can build and to avoid the init manager check in the nativesdk case so add those fixes.

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 = "nodistro") 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 (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
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.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: 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.
