Rather than attempting to condition the entire tree to machine SRCREV (since
we don't know what branch will be built), we can instead wait until patching
has completed and then confirm that we are indeed building a decendant of the
specified SRCREV. The result is a much simpler check, and no mangling of the
tree.

Parsing the output of git show is error prone, since it changes based on
the type of issue with bad comit IDs. Since the output is no longer used
in the case of a valid ref, we can switch to git-cat-file and simply

do_validate_branches checks to ensure that a valid machine SRCREV was
set. A test against an empty SRCREV is done in two separate locations,
we only need one, since the first check immediately returns and the
second check never hits.
At the same time, we can stop referring to the same commit hash by
3 different names. Instead we assign to a local variable at the
top of the routine, and refer to it at all times.

We allow inheriting recipes to control the kconfig mode used by merge_config.sh
via the KCONFIG_MODE variable. An error crept into the variable reference, and
since it is not quoted, the true condition always runs.
The result is that operations without an explicit kconfig mode cannot trigger
allnoconfig for defconfig builds, which can result in some options being
dropped from the final .config.
Quoting the reference allows it to evaluate properly.

The bbclass did the following:
do_diffconfig[depends] += "virtual/kernel:do_kernel_configme"
This clearly introduces a cross-kernel task dependency if the recipe
inheriting this class isn't the preferred provider of virtual/kernel, which is
obviously wrong, but further, will break the build if a kernel-yocto based
kernel is parsed and not skipped, but virtual/kernel refers to
a non-kernel-yocto recipe, which would not have the do_kernel_configme task.
Work around this by adding the in-recipe task dep programmatically with
bb.build.addtask when do_diffconfig exists.

'git branch' may use ANSI escape codes in its output (to provide colour)
which doesn't play well with commands expecting pure plain text, e.g.
fatal: '^[[31mmaster^[[m' is not a valid branch name.
Use the --no-color option to ensure all branch names are plain text.

The validate_branches routine is responsible for ensuring that the specified
SRCREV exists, and that the tree has been prepared for eventual patching
starting directly from that SRCREV.
On exit, the routine checks out the specified machine branch and the
preparation is complete .. except if a KMETA branch isn't used, we exit
early since the branch can't be validated.
To make the exit condition consistent for all cases, we can move the
KMETA validation inside a conditional and allow the same exit path for
both cases.

While non-git kernel repos are not the preferred format for a kernel upstream,
they are supported. Depending on the creator of the archive the expanded
source directory name varies. If the recipe for the kernel doesn't properly
set S to the right value, a cryptic git error message is produced. We can
detect the situation and offer some advice on how to fix the issue.
A second check is also added in this commit for archive based kernel repos
which won't have a SRCREV to validate. If we have no SRCREV or SRCREV is
INVALID, we can exit the branch validation step immediately. This saves yet
another cryptic git error message and simplifies a custom tgz based recipe.

These are bug fixes, usability changes as well as the removal of the
guilt dependency. During the uprev of the guilt package, the amount of
circumvention of the typical guilt workflow and checks meant that using
it as a series -> branch manager was no longer appropriate. As a result
a new tools kgit-s2q (series 2 queue) was created based on git-quiltimport,
git am, and the LTSI tree generation scripts.
The result is better series to branch validation, faster application and
a simpler management model. This tool is backwards compatible with any
tree previously constructed with guilt. We are now "guilt free"

commit 61001aa [kernel-yocto: respect SRC_URI modified branch selection]
changed branch processing such that a branch specified in the SRC_URI
would set the branch forced as the build branch.
This change broke compatibility with the yocto-bsp, linux-yocto-custom
based recipes. These recipes specify the branch to be built via KBRANCH,
but allow the fetcher to use master for keeping the repository up to
date. This means that no explicit branch is set in the SRC_URI and the
routines return the default branch of 'master', which is not what is
set in KBRANCH.
To support this case, we simply pass a default branch into the routine
returning the branch to build, and ensure that the default is KBRANCH
so if no branch is passed in the SRC_URI, KBRANCH is always built.

The linux-yocto recipes themselves always set S="${WORKDIR}/linux" and
arrange for the fetcher default of ${WORKDIR}/git to be renamed before
building.
Part of this rename involves an assumption that the directory used by
the fetcher can be removed as part of the renaming process, or in fact
that renaming is required.
If a derived recipe uses S="${WORKDIR}/git", the checkout phase fails
since the kernel source is removed as part of the processing.
To fix this the code now detects this situation and does not clean the
source directory before renaming the fetcher default (and in fact does
not rename it at all).

Although the setting of KBRANCH is the suggested/primary way to interact with
the yocto kern-tools and the fetcher, some users may be more comfortable
modifying the SRC_URI branch parameter directly.
If they do, the tools will not force their branch and build output will be
different then they expect, in non obvious ways.
It's easy enough to detect this scenario, but checking the SRC_URI in the
same way that the git fetcher checks for the branch (and SRCREV). If we take
the value from the SRC_URI and use it directly in the patch/validate/update
routines, we'll stay consistent with KBRANCH if it is used, and also
automatically adapt to a manually changed branch parameter on the SRC_URI.
For all other users, there are no visible or behavioural changes as a result
of this change

To support configurations where active development is not being done within
the oe/bitbake build environment and restricted bandwidth situations, this
commit allows the SRC_URI to point to a kernel tgz instead of a full git
repository.
Outside of the upstream tgz instead of a kernel git repository, the
restrictions, config and patch process is the same as any linux-yocto-custom
recipe.
An example linux-yocto-custom based recipe would have a configuration like
this to build the 3.7 kernel, using an externally supplied config, from the
3.7 tgz:
SRC_URI = "http://kernel.org/pub/linux/kernel/v3.0/linux-3.7.tar.bz2"
PV = "3.7"
S = "${WORKDIR}/linux-3.7"
SRC_URI[md5sum] = "5323f3faadd051e83af605a63be5ea2e"
SRC_URI[sha256sum] = "dc08d87a579fe2918362e6666e503a95a76296419195cb499aa9dd4dbe171a9e"

To promote the reuse and sharing of configuration fragments this change
allows any kernel-yocto based recipe to have multiple alternate git repositories
which provide kernel feature directory trees listed on the SRC_URI.
These feature directories are in addition to any in-tree kernel meta data branches
that may be available (described via the KMETA variable in linux-yocto recipes).
Features found within these directories can be used from recipes via the
KERNEL_FEATURES variable. Features found within a feature directory are free
to include any other features that are available in any directories. In both
cases the path to a feature description (a .scc file) is relative to the
root of a given feature directory (which is how existing .scc files work)
The search order for features is determined by the order that repositories
appear on the SRC_URI.
Normal SRC_URI rules apply to any repository that is added as a kernel
feature container. A SRCREV must be supplied and it must be unpacked to
a unique directory, which is controlled via the "destsuffic" url parameter.
In addition to these standard requirements, any kernel feature repository
reference should identify itself via the "type=kmeta" url parameter. If
type=kmeta is not supplied, the repository will not be processed for
kernel features.
As an example, the following in a linux-yocto bbappend makes two additional
feature directories available to KERNEL_FEATURES and fragments.
SRC_URI += "git://git.yoctoproject.org/yocto-kernel-cache;protocol=git;branch=master;type=kmeta;name=feat1;destsuffix=kernel-cache/"
SRC_URI += "git://${KSRC_linux_yocto_3_4};protocol=file;branch=meta;name=feat2;type=kmeta;destsuffix=kernel-features-experimental/"
SRCREV_feat1 = "${AUTOREV}"
SRCREV_feat2 = "${AUTOREV}"

We should always leave the tree on a BSP branch or master when
do_validate_branches completes to avoid modifying version tracked
files are part of the build process. Modifying these files will lead
to errors when changing branches, since the contents would be lost.
This is evident in the case that a the meta branch is reset to a
known SRCREV and the tree was left on the meta branch. This branch
tracks the meta/meta-series, and other artifacts of the original
tree construction. When the build process runs, it updates these same
files, which creates a conflict when switching branches.
This has been fixed in the tree construction scripts to not track
these files, but a secondary fix is also required of not leaving
the build on these branches, to allow arbitrary trees to be built.

Having a meta branch is not strictly required by the tools (and
recipes like linux-yocto-custom do not have meta branches), but the
comments in the kernel-yocto.bbclass could lead someone to think that
it was required.
This commit clearifies the comment to the following:
# We can fix up the kernel repository even if it wasn't a bare clone.

It was reported that the kernel configuration checks for custom yocto
kernels had the following output:
NOTE: validating kernel configuration
grep: /meta-series: No such file or directory
grep: /meta-series: No such file or directory
WARNING: Can't find any BSP hardware or required configuration fragments.
WARNING: Looked at //cfg///hdw_frags.txt and //cfg///required_frags.txt in directory: //cfg//
NOTE: Tasks Summary: Attempted 375 tasks of which 367 didn't need to be rerun and all succeeded.
which is not inspire confidence in the output of the process.
Completely inhibiting the check is one option to remove the messages,
but that removes the ability see output, which can help move users to
a better or more fully configured linux-yocto based kernel.
To fix this, we have to ensure that the path to the meta-series is
always valid, and that the tools can deal with not all files existing
in the audit directory.
Since custom yocto kernels do not set KMETA (they don't have a meta branch),
we ensure that a default of 'meta' is passed to the audit ('meta' is always
valid), and that kconf_check itself can deal with an incomplete set of
input audit files.
The net result is output like this (using a defconfig with invalid options
for the kernel being built):
NOTE: validating kernel configuration
This BSP sets 19 invalid/obsolete kernel options.
These config options are not offered anywhere within this kernel.

do_validate_branches ensures that the desired SRCREV is at
the tip of every branch that contains the revision. To do this,
it looks for containing branches and processes them.
This processing was mistakenly placed before the check for an
invalid SRCREV, hence a git error message is seen in the log
if a bad SRCREV is used, rather than a clear message.
reordering the checks, and fixing a check for master, ensures
that clear messages are generated in all cases.

Otherwise the branch that the machine description creates will

One of the patch backends to linux-yocto is guilt, which normally
tracks patches under .git. But .git isn't something that can be
checked into a SCM and repeated. So it has been moved under meta/patches
and committed to the meta branch.
If devshell is used, GUILT_BASE isn't set, so patch manipulations will
fail. We export GUILT_BASE and point it at the meta directory when
devshell is invoked for linux-yocto.

In order to support repositories of various types (with or without
meta data, branched, pristine, custom, etc) information about the
type of processing that is required was passed to the processing
phases via variables.
The combination of variables involved in coordinating the processing
creates a learning curve and overly complicates recipe extensions.
With minor tweaks to the kern-tools, adding flexibility and keying
off the existence of the meta branch it is possible to remove all

During testing/extension of the linux-yocto-tiny kernel it was found that
defconfigs were not always properly applied. This was due to two issues:
- not being able to fully control the order of objects applied to the
git tree on the SRC_URI
- defconfigs triggering --allnoconfig before being applied
To fix this, the recipe space code that previously detected and generated
automatic features moves back to the kernel tools (where it was before) and
is updated to also process .cfg and defconfigs. Moving this back to the
tools allow other recipes to automatically benefit from the additional
support.
The second issue is addressed by allowing configme to take --alldefconfig
when a recipe wishes to pass a defconfig and override the default
behaviour.

There are a few extra task that modify the source tree that should
be removed when externalsrc is inherited by a recipe that uses a
linux-yocto tree.
Adding those tasks to SRCTREECOVEREDTASKS means that they are skipped
and externalsrc works as intended.

During the work to enhance the ability to specify out of tree kernel
features, an assumption was made about PN being part of a patch
path. This assumption is incorrect, since patches can be anywhere in
the valid FILESPATH.
To make locating the patches in WORKDIR simple, we can just query
patch.bbclass and return both the absolute directory of the patch
and the subdirectory as it was specified on the src_uri.

The steps in do_kernel_checkout modify the source tree in WORKDIR.
If it is called multiple times, or interrupted, the tree is left
in an inconsistent state.
This change adds protections around branch names, and around the
manipulations of directories to ensure that it is safe to call
at any point.

Not all users of the checkout phase of linux-yocto have all
branches present. This is normal, and should be supported. By
checking for an empty KBRANCH we can avoid validating a branch
that isn't supposed to exist.

The typical workflow for linux-yocto simply uses a remote
upstream repository (Whether it is mirrored or not), and in this
case there are no issues with consistency in the format of the
resository that is unpacked into the WORKDIR.
When working with a local linux-yocto repository for kernel
development the remote vs local branches is not always consistent
between repositories.
The suggested/documented workflow has always been to use a
bare clone of linux-yocto, and use a second working tree repository
for development. Changes flow from the working tree to the bare
clone and then into the working directory for build. A common
mistake that happens with this workflow is that the non-bare,
working repository is used instead of the bare clone version.
If a non-bare repository is reference by the SRC_URI, then the
branches that are fetched into WORKDIR are not consitent. If the
MACHINE and META branches are not present, cryptic build errors
will result.
To solve this problem, the checkout code has been changed in
several ways:
- works with a newly proposed 'bareclone' option to bitbake
- detects if a bareclone is present in WORKDIR or not and
adjustst the checkout accordingly.
- if a non-bare clone is detected, machine and meta branches
are checked. If they are not present, or can't be created
a clear error message is produced
- instead of manipulating the refs directly in the git tree,
local tracking branches are (quietly) created for remote
branches. Enabling a better workflow in the WORKDIR kernel
repository.
This has been tested with linux-yocto remote upstreams, local
bare and non-bare respositories. All builds succeed or fail
with clear error messages.

In a similar manner to calling the patch.bbclass to locate patches that
were listed on the SRC_URI, it is also useful to query about 'other' items
that are on the SRC_URI. In the case of linux-yocto, it allows us to
know about kernel features that were specific on the URI and then apply
them to the current tree.
