* Fixed:
The netmap has been blacklisted in
meta-networking/recipes-kernel/netmap/netmap_git.bb, but lib32-netmap still can
be built (suppose it doesn't depend on another broken recipe netmap-modules, it
is a little complicated, will talk below):
$ bitbake lib32-netmap
This is because of the old code masks on bb.event.ConfigParsed which can only
handle global blacklist, netmap sets blacklist in the recipe, so it can't be
handled, and lib32-netmap can be built. which was incorrect:
blacklist_multilib_eventhandler[eventmask] = "bb.event.ConfigParsed"
Move multilib code into multilib.bbclass can fix the problem easily:
$ bitbake lib32-netmap
ERROR: Nothing PROVIDES 'lib32-netmap'
ERROR: lib32-netmap was skipped: Recipe is blacklisted: BROKEN: <foo>
* Not fixed
Another problem is netmap-modules has also been blacklisted in the recipe, and
the recipe inherits module.bbclass, so multilib.bbclass doesn't handle it as the
code shows:
# There should only be one kernel in multilib configs
# We also skip multilib setup for module packages.
provides = (e.data.getVar("PROVIDES") or "").split()
if "virtual/kernel" in provides or bb.data.inherits_class('module-base', e.data):
raise bb.parse.SkipPackage("We shouldn't have multilib variants for the kernel")
And netmap-modules provides lib32-netmap-modules which is handled in
multilib_global.bbclass, so bitbake lib32-netmap-modules can't show
the blacklist message:
$ bitbake netmap-modules
ERROR: Nothing PROVIDES 'netmap-modules'
ERROR: netmap-modules was skipped: Recipe is blacklisted: BROKEN: <foo>
ERROR: netmap-modules was skipped: We shouldn't have multilib variants for the kernel
$ bitbake lib32-netmap-modules
ERROR: Nothing PROVIDES 'lib32-netmap-modules'. Close matches:
netmap-modules
netmap-modules
lib32-fbset-modes
Note the different messages between netmap-modules and lib32-netmap-modules.
This is because multilib.bbclass doesn't handle the "module" recipe so
there is no PN called lib32-netmap-modules, therefore blacklist.bbclass can't
handle it.
Note, there are two "netmap-modules" which needs to be fixed later.

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.
