* this is mostly for backwards compatibility and to share binary feed like it was before, but now without missing different -mtune in it * if you want to build some package with -mtune add something like this to your distro config DEFAULTTUNE_qemuarm_pn-openssl = "arm926ejs" DEFAULTTUNE_qemuarmx_pn-openssl = "xscale" be aware that if you do this you should do it also for all packages which depends on openssl because if you dont and you build e.g. dhcp, then dhcp build for arm926ejs (even with DEFAULTTUNE armv5te) will depend on openssl with arm926ejs, so dhcp in armv5te feed will be rebuild after each MACHINE switch. * cortexm3, cortexr4, iwmmx and ep9312 are using own DEFAULTTUNE because they define also different -march * shared feeds are armv4t: arm920t, arm9tdmi armv5te: arm926ejs, xscale armv7a-neon: cortexa8, cortexa9 (From OE-Core rev: a11bdc36a1be18cc5aa14682b2a2c9ee83141f51) Signed-off-by: Martin Jansa <Martin.Jansa@gmail.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.
