This makes the external module compilation a bit more robust for cases where external module recipes may be passing extra params to make via EXTRA_OEMAKE, and more than often one needs to pass M=$(PWD) when building external modules and if we use EXTRA_OEMAKE that would mean that it would appear in do_make_scripts as well and since we are only changing the reference kernel src tree here it will not run the make scripts in desired directory. It is also well explained in top makefile in kernel tree around line# 1335 in 3.4 |else # KBUILD_EXTMOD | |### |# External module support. |# When building external modules the kernel used as basis is considered |# read-only, and no consistency checks are made and the make |# system is not used on the basis kernel. If updates are required |# in the basis kernel ordinary make commands (without M=...) must |# be used. Therefore passing M=... will not do the updates in the basis kernel as expected with 'make scripts' so we have to bypass EXTRA_OEMAKE [Yocto #3787] (From OE-Core rev: 0e0a5ee405bab478f35690e95219a1e5f2ac7aa6) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Saul Wold <sgw@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.
