If you build virtual/kernel, then change PREFERRED_PROVIDER_virtual/kernel from say "linux-yocto" to "linux-yocto-dev", you see errors from the sysroot about overlapping files. The automatic uninstall logic doesn't trigger since the other recipes is still technically parsed/buildable. What we can do is look at the value of PREFERRED_PROVIDER_virtual/X and raise SkipRecipe (skip parsing) if it provides this thing and its not selected. We skip cases no preferred provider is set, or the value is in MULTI_PROVIDER_WHITELIST.We also inform the user if they try to build something which conflicts with the configuration: $ bitbake linux-yocto-tiny ERROR: Nothing PROVIDES 'linux-yocto-tiny' ERROR: linux-yocto-tiny was skipped: PREFERRED_PROVIDER_virtual/kernel set to linux-yocto, not linux-yocto-tiny [YOCTO #4102] (From OE-Core rev: 9a3b992b7339f7aa892f1dff7d159747630b045d) 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 = "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-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.
