kernel configuration validation takes place between two files. An
unprocessed configuration file (which is all the options found in
the various configuration fragments) and the final .config produced
by the lkc.
The unprocessed configuration file's name historically is based on
the name of the branch that was used to build the BSP. But with the
ability to map machine names to arbitrary branches, this is no longer
always true.
Searching for the pattern *-config-* in the meta subdirectory will
only match the config file, and frees the config validation phase
from being concerned with what branch was used to build the BSP.

After constructing a kernel configuration file it then needs
to be located in the tree so it can be audited against the
final .config. The previous string that was used for the search
pattern contains the kernel version. If the recipe space kernel
version and internal tree version are out of sync, this will
cause the constructed config to not be found. By removing the
version from the search string, we can still find out config and
gracefully adapt to minor version skew.

When building an external tree or bootstrapping a BSP the
external branch may not have been checked out. The tools now ensure
that the tree is ready for configuration, so we no longer need to
force the checkout of the external branch.
This change is coupled with some kern tools tweaks as follows:
40d9bab updateme: allow the location of board descriptions based on defines
59859ca createme: use branch name when creating meta data
91b4275 configme: determine meta branch based on directories, not branch naming
f5a915c kgit-meta: make branch creation and renaming more robust

For kernel's that use a split source/object build the copy
of defconfig to {S} in the base kernel class is problematic.
The previous solution for this was to override the do_configure
of the base kernel class in a subclass. While this is still
a viable/valid option, it does mean that changes to the base
do_configure will be missed.
The solution to this is to copy a defconfig to {B} which is
typically the same as {S}, so most kernel recipes won't see or
care about this change.
With this change in place, linux-yocto.bbclass can drop its
override of do_configure.
Tested with linux-yocto and oe linux recipes.

If you include a bitbake variable as a comment in a shell function
then it gets expanded by the bitbake signature handling code.
This could be classed as a bug or a feature depending on your viewpoint
(e.g. a multiline variable included in a comment could actually contain

Since we don't always want kernel-yocto to reparse this changes the

There are valid reasons to build repositories without meta
data present and there are times when this is an error. This
change adds sanity tests to the build process to detect missing
meta data and throw an informative error message.
Sanity checking is only triggered from recipes (linux-yocto)
that always require meta data to be present. Other recipes
are not impacted and can auto-generate meta data as required.
Without this change the build process suceeds, but incorrect
meta data will be used (with no user knowledge), which is not
the desired behaviour.

To support quick uprev and testing, it is desireable to build

the meta data can be automatically created or provided externally.
This commit supports the first situation by detecting the lack

CONFIG_SND_AC97_CODEC=m
CONFIG_SND_ENS1370=m
CONFIG_SND_INTEL8X0=m
CONFIG_AC97_BUS=m
The mechanism to trigger these options is in the form of an
optional kernel feature that is only appended for qemux86
and qemux86-64, but is contained within the kernel tree.
This allows several things:
- the options to be available/shared for all boards
- the options to be in tree
- to not add the options to every board, which unecessarily
bloats the default configuration.

In order to build BSPs that were not already integrated into
the upstream linux yocto kernel AND keep the git fetcher happy,
some fairly complex anonymous python sections were required.
These sections cause problems with variable expansion and SRCREV
processing.
With the updated git fetcher code, we can streamline the BSP
boostrapping process and drop 99% of the anonymous python code.
This commit has the following changes to support BSP boot strapping
and simplication for existing BSPs.
- KMETA is set per-recipe rather than in python code
- undefined machines are no longer used, but instead common
branch names are set per-recipe
- fallback machine SRCREVs are present in the default revisions
file
- A new variable YOCTO_KERNEL_EXTERNAL_BRANCH should be set in
the local.conf for new BSPs instead of being programatically
determined in the anonymous python.
- No more explicity KMACHINE variable expansion and manipulation,
since the tools and build phases no longer require it due
to the per-recipe fallbacks.
Integrated/merged BSPs are unaffected by the changes and have been
regression tested.

The python code in this class file needs to run before SRCPV is expanded
and calls into the fetcher are made. To so this we create a python function
and prepend a call to it before SRCPV's get_srcrev() call.
Ugly, ugly, ugly but the ordering is guaranteed.
If this doesn't happen, the fetcher can end up in two different states and
there may be caching implications of this.

By default the linux-yocto recipes operate on the current branch
and use it as a trigger to locate the description of a board. This
model works well when using the git repo outside of a build system
since the commands can be simply invoked and will do something
useful. However, it does mean that you can't have two BSPs that
differ only by configuration, building out of a single branch
in the repository.
This means that you must have many branches for very similar
BSPs. This model is still preferred, but having the choice of
branching strategies is better.
With this change we can have multiple BSPs using a single branch
with the preferred description being hinted from the build
system by passing the $machine value to updateme/configme.

BSPs are built from a particular branch of the kernel repository
which is specfied via the mapping of MACHINE to KMACHINE. Unless
a global branch is being forced (like libc headers), KMACHINE
is an override on a per machine basis.
Because KMACHINE is typically override we must first try the
most specific variant KMACHINE_<machine> and if that is undefined
look for a fallack default. This allows any combination of
variables to work (and at the time the anonymous python
executes) safely and get us a properly defined branch for the
fetcher and build.

The existing 2.6.34 kernel tree uses _ where poky typically
uses -. This is a historical artifact, since working with
gnu Make and shells means avoiding - is wise. The opposite
is true in Yocto.
To avoid using the _ reserved character wherever possible
we can simply remove it from the branch names in the
new 2.6.37 kernel, but to keep the content stable in the
0.9 2.6.34 kernel, we map _ to - for the purposes of
packaging.
To further faciliate this switch, the branch names no
longer need to be shortened in the KMACHINE mappings, but
can be fully specified and the tools/processing adapt as
required. This gives us the flexibility to map multiple
boards to a single branch for building.

In order to extend and create more kernel recipes based on the
supported yocto kernel common routines need to be placed in
re-usable blocks.
To accomplish this meta/recipes-kernel/linux/linux-yocto_git.bb
is broken into three parts:
- meta/classes/kernel-yocto.bbclass: contains common routines
for checking out and configuring a yocto kernel git repository.
This should be inherited by recipes that need this functionality.
- meta/recipes-kernel/linux/linux-yocto.inc: Contains the machine
mappings, compatibility, build directives and common task
definitions for a yocto kernel based recipe. This inherits
kernel-yocto, and is the typical point of entry for other recipes.
- meta/recipes-kernel/linux/linuux-tools.inc: tasks and function definitions
for kernel recipes that want to build/export perf
It also updates the linux-yocto recipe to default to 2.6.37.
As part of the update to 2.6.37 the branch naming and conventions
have been modified to show inheritance, and be more generic.
For example:
master
meta
yocto/base
yocto/standard/arm_versatile_926ejs
yocto/standard/base
yocto/standard/beagleboard
yocto/standard/common_pc/atom-pc
yocto/standard/common_pc/base
yocto/standard/common_pc_64
yocto/standard/fsl-mpc8315e-rdb
yocto/standard/intel_atom_z530
yocto/standard/intel_core_qm57_pch
yocto/standard/mti_malta32_be
yocto/standard/preempt_rt/base
yocto/standard/preempt_rt/common_pc
yocto/standard/preempt_rt/common_pc_64
yocto/standard/preempt_rt/intel_atom_z530
yocto/standard/preempt_rt/intel_core_qm57_pch
yocto/standard/qemu_ppc32
yocto/standard/routerstationpro
In this structure:
master: tracks the mainline kernel
meta: meta information for the BSPs and kernel features
yocto/base: baseline kernel branch
yocto/standard/base: 'standard' kernel, contains features
and configs for all BSPs
yocto/standard/<machine>: represents a BSP with specific
features or configurations
The tools, tree and libc-headers have all been updated to
deal with this new structure. Also in addition to dealing with
the new structure, they continue to work with the existing
tree and will adapt at runtime to the differences.
The linux-yocto-stable_git.bb recipe continues to build the
2.6.34 based tree,and linux-yocto_git.bb builds 2.6.37. As
boards are enabled for the new kernel they will move from
-stable to the development kernel. As of now, only the
emulated targets have moved to 2.6.37-rcX
