Robert P. J. Day reported that configuration fragments and kernel
features were not being found when organized in a particular manner:
linux
- $BOARD
- mm.patch
- mm.scc
- ssd_sil.cfg
- ssd_sil.patch
- ssd_sil.scc
- uio.cfg
.. etc
There was a bug in the tools that did not handle the mix of subdirs
properly and ended up leaving a trailing / on the elements *not* in
the $BOARD subdir. As a result, the configuration fragments were not
properly found when searching the include paths, and a configuration
failure was triggered (due to missing files).
This change tweaks the tools to always check a path with and without
a trailing / when processing config fragments so they can be later
found when processing the configuration of the kernel.

With the recent changes to improve patch processing times, the ability
to skip already applied patches is not active by default.
The automatic detection and resume was hiding issues with the include
files generated by scripts like yocto-bsp.
If a .scc file that contains a patch is included twice, the patch is
applied twice, and the second appliation fails for obvious reasons.
We can partially fix this by ensuring that already included
configuration fragments are not forced into the meta-series.
.scc files that are explicitly listed twice will continue to fail, and
recipes must be modified to avoid this.

Updating the kern-tools SRCREV to import the following fix:
kgit-meta: resume after last applied patch
When the auto-resume (resume point detection) was removed from the
processing of a meta-series, it ignored the fact that a single patch
series may in fact be processed a number of times.
Two layers patching a kernel will generate two different runs on the
same branch, which always start at patch one. This will obviously
break with duplicate patches.
To avoid this, we simply track the last patch applied, and
explicitly
tell the patch scripts where to start. This gets us resume
functionality, without the overhead of resume point detection.

Updating the kern-tools SRCREV to integrat the following commit:
patching: only validate user supplied patches by default
Previously the patching tools would consider both system and user
supplied patches in the same manner .. they are simply a series of
patches to be applied to a branch, and that the scripts should determine
where in the series to start (based on what is already on the
branch).
This detection was causing a few problems:
- time consuming
- starting in the middle of a series when intermediate patches
were merged to a branch.
To solve both the performance and start detection, we instead simply
note the transition from system (i.e. already defined features and
series) and user/recipe supplied patches. When the transition is noted,
the system will start pushing ALL patches without doing autoresume
detection.
Control in keeping the series up to date is passed to the user, and
consistent behaviour/performance is achieved.

It is possible that recipe specific tasks, or build processes drop
files into the kernel source directory. These files can cause problems
with the meta data detection in the kern-tools.
With this change, we have a single unified meta data detection routine,
that logs the result in a new file ".metadir", which subsequent scripts
can find, and use, thereby avoid repeating the same check many times.
We also enhance the check to look for a sentinel file in a proper meta
directory, to avoid false positives when an unexpected kernel process
leaves an uncommitted directory in the kernel dir.

When fixing a kernel configuration warning, it is often necessary to
modify the kernel's meta-data and re-run the tools to update and
re-audit the config. This implies that the patch, config and audit
steps are run multiple times.
The tools had a bug that would incorrectly restore old meta-data
versus using updated configuration. Updating the kern-tools SRCREV
to fix the issue.

processing time:
kgit-meta: skip patches on non-leaf nodes
In a similar way as commit 0768d697 [kgit-meta: dont run kgit-s2q
for
non-leaf nodes], we can save even more processing time by not even
analysing and linking patches if we aren't on the leaf node of the
tree.
This early exit can save nearly 95% of the time required to "patch"
a tree when no changes are actually applied.

After a linux-yocto style kernel is configured, a kernel configuration
audit is executed to detect common errors or issues with the config.
This output used to be visible, but was made less obvious to not alarm
users unnecessarily (since some configuration issues are acceptable).
There are some classes of configuration issue that are worth being
visible, and that is specified configuration values that do not make the
final .config. These dropped options can result in any number of runtime
failures, so flagging them at build time makes sense.
The visibility of auditing is controlled by KCONF_AUDIT_LEVEL:
0: no reporting
1: report options that are specified, but not in the final config
2: report options that are not hardware related, but set by a BSP
The default level is 1, with level 2 and above being for BSP development
only.
If these conditions are detected, warnings will be generated as follows:
WARNING: [kernel config]: specified values did not make it into the
kernel's final configuration:
Value requested for CONFIG_SND_PCSP not in final ".config"
Requested value: "CONFIG_SND_PCSP=y"
Actual value set: ""
or
WARNING: [kernel config]: BSP specified non-hw configuration:
CONFIG_BLOCK
CONFIG_CFG80211_WEXT
CONFIG_CORDIC
CONFIG_CRC8
CONFIG_EFIVAR_FS
CONFIG_EFI_PARTITION
CONFIG_NET
CONFIG_NETDEVICES
CONFIG_PARTITION_ADVANCED
CONFIG_WEXT_CORE
CONFIG_WEXT_PROC
CONFIG_WIRELESS
At this point thse are only a warnings, since there needs to be time for
layers and configuration fragments to be validated against this new
check.

During patch processing a consolidated set of configs, patches and directives
is created under the kernel source tree being modified. During that processing,
absolutely paths are converted to relative. It has been found that if directories
are sufficiently similar, like so:
/path/to/my-linux
/path/to/my-linux-3.16
The processing will chop to much of some paths, resulting in invalid relative
directories (like -3.16 in the above example).

From the kern-tools commit:
tools: allow meta directories that are not the same as the branch name
With this change it is now possible to have a meta branch with meta data
in a directory that is not the same name as the branch.
The changes to three parts of the build are required to discover the name
of the meta directory by relying on the fact that in a clean/proper build
the meta directory is the only untracked, top level directory in the build.
As such, we can restore a checkpoint and then examine the build directory
to determine the meta directory name .. avoiding any new variables to
indicate this to the scripts and build system.

A lot of our recipes had short one-line DESCRIPTION values and no
SUMMARY value set. In this case it's much better to just set SUMMARY
since DESCRIPTION is defaulted from SUMMARY anyway and then the SUMMARY
is at least useful. I also took the opportunity to fix up a lot of the
new SUMMARY values, making them concisely explain the function of the
recipe / package where possible.

Updating the kern-tools SRCREV to import the following change:
kgit-s2q: always update ORIG_HEAD after applying changes
In situations where git am fails to apply patches, and git apply is used,
we must update ORIG_HEAD as well as HEAD. This is required, since if the
next patch in the queue also fails git am application, it will reset to
ORIG_HEAD before using git apply. If we haven't updated ORIG_HEAD, we'll
end up warping back to the top of the branch each time.
This problem can only be seen in very specific situations, in particular if
a generated BSP branches from qemuppc, and has a series of non git "am able"
patches. We fail, since all of the qemuppc patches are not applied due to
the branch head constantly being reset.

Updating the kern-toosl SRCREV to pick up the following fix:
previous versions of the kern-tools supported the ability to import a bare
patch, with no From: Subject: or other identifying fields that are typically
in a full commit.
The same type of commit with kgit-s2q will prompt for a author ID, just
as git-quilt-import does. In build system environment that leads to an
infinite loop and the commit is never pushed.
To fix this issue, we add an interactive flag (-i), that when passed the
prompt based behaviour is used. When it isn't passed (the default), the following
name and email will be used for the git author:
GIT_AUTHOR_NAME="invalid_git config"
GIT_AUTHOR_EMAIL="<unknown@unknown>"
And a bare/incomplete header patch will be applied.

Updating the kern-tools SRCREV with the following fix:
Updateme is responsible for updating an existing meta-series with new patches,
configs and tree manipulations. To do this, it first checks for an existing
board description and generates one if required. It then searches for features
and fragments to be applied for the tree.
There were two problems:
- A top level board description is detected via the presence of "define"
directives that indicate the board name, the arch and kernel type. The
test for define would match on patches or fragments with 'define' in their
name, and would incorrectly use that file as the top level board description.
This is fixed by ensuring that only defines at the start of a line, or preceded
by whitepace match.
- When searching for features that were indicated as 'addon' or 'optional', the
search would find, and apply, any feature with the passed name as substring
versus an exact match.
This is fixed by ensuring that the matched feature name is /<feature name>
versus <feature name>

Updating the SCRCREV to pick up the following fix
updateme: use absolute path for generated BSP descriptions
When a custom BSP is used, a top level BSP is generated by the tools and fed
to the build system just as a user defined BSP would be located and
passed. The location of the generated file is placed in the top_tgt file,
which is used by subsequent stages. A relative path was being placed into
top_tgt, which binds the build to a particular directory structure and
working directory.
The location of parts of the build have changed, and this relative path is
no longer accurate. Changing it to an absolute path solve the build issues
related to custom BSPs.

A regression was introduced when implementing the ability to restrict
configuration values via include directives. Only patch and config files that
were local to a feature directory could be found. While this doesn't impact
most users of the tools, it is an issue that needs to be fixed.
Additionally, the regex that detected flags passed to includes was not
specific enough, and unfortunately named feature files would match. This
resulted in features like standard-nocfg.scc inhibiting all configuration
items, even base configs.

One of the features introduced early on in the 1.4 release cycle was the
ability to include a kernel feature, but only get its patches and not configs
(and vice versa).
As it turns out, this only was exercised recently and once a single include
with dropped configs was started, ALL configuration values following the
commit were dropped.
To fix the problem, the processing of kernel features has been split into
two. Where the features are preprocessed and the assembled/complete file is
used to generate the meta-series (which is later applied to the tree). The
logic of the tools is the same, but the two phases of processing allows
configuration values to be excluded properly and simply, while keeping the
logic for modifying the tree in a separate step.
All changes are invisible to the user, and are done within the existing
scripts and build system bindings. Output series and manipulations to
the tree are the same as they were before this change.

kconf_check: fix new Kconfig detection
One of the functions of the kernel configuration audit is to notify
the user if Kconfig* files have been removed from the kernel, and
also to notify of new Kconfig files.
New Kconfig files should be classified as hardware or non-hardware to
allow BSP audits to notify if boards are setting values that they
shouldn't, hence why notifying about new "buckets" is important.

updateme/scc: allow config fragment exclusion
It is common to need the features (patches, git operations) of a
branch, but not want the kernel configuration fragments of a given
branch. To allow this, we provide a new include flag "nocfg".
When this flag is used, all of the configuration fragments included
by the targetted feature will not be applied to the current build,
with one exception, a base/critical fragment can force it's config
values, since without them, the system would not be functional.
Example:
include ktypes/standard/standard.scc nocfg

To allow for parameter validation and sanity checking, wrap "git merge"

There are no changes to arguments, and existing 'git merge' commands

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/"

Updating the SRCREV to import the following changes.
[updateme: find the board description with the highest score]
This removes the requirement that a custom linux-yocto .scc file have
define KTYPE <foo>, where <foo> is typically "standard". The tools can
now match on a .scc file that only matches the board, but will still
chose one that matches the board and kernel type, if available.
[updateme: allow for tabs or spaces in defines]
define KMACHINE<tab>$MACHINE was missed by the regex.
[scc/kgit-meta: detect and avoid duplicating patching]
To allow feature description to be included multiple times, they were
previously split into -enable and 'patch' descriptions. With this change
the patches will be detected as already included, and skipped
automatically. Removing the need to do this split. It also cleans up
the ability to warn about multiple includes.
[kconf_check: add "verify" configuration fragment type]
This adds the ability for a BSP to have a kernel configuration
fragment that lists options that must be present. If they are not
present it is a hard error. "required" is a similar fragment, but
it adds them to the build, and audits them at the end, but does
not abort the build if they are present. This is a minor distinction,
but one that is useful when creating flexible, shared kernel config
structures.
[kconf_check: improve kernel audit report formatting]
[kconf_check: perform validity checks on non-hardware options]
[kconf_check: cleanups and verbose flag]
The existing output was verbose and not always useful to the reader.
This change makes the output more compact, audits non-hardware options
and gives information
[invalid (54)]: meta/cfg/preempt-rt/common-pc/invalid.cfg
This BSP sets config options that are not offered anywhere within this kernel

Bumping the kern-tools SRCREV to pickup the following change:
[
kconf_check: fix find warning
When searching for all available Kconfig files, kconf_check was using
$meta_dir instead of $META_DIR. This resulted in a truncated path and
the following warning:
find: warning: -path $oe-path/linux/ will not match anything because it ends with /.
Using the proper variable removes the warning and make sure that we
do actually search all relevant directories.

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.
The full list can be found in your kernel src dir at:

Importing the following tools SRCREV:
kgit-meta: exclude explicit branches from name calculations
kernel branches are constructed during patching of the tree by
constructing a '/' based hierarchy of names as each branch
directive is encountered.
But if a "branch $name $branchpoint" is used, the entire branch
name is supplied so no additions to the hierarchy should
happen. As such, that type of branch command should not be part
of branch name calculation and preparation.

When patches fail to apply, the status of all pending patches should
be exported to the logs and to the user. Currently, a missing export
of GUILT_BASE makes it look more like an internal error, than a 'normal'
patch failure:
| [ERROR] unable to complete push
| pending patches are:
| Patches directory doesn't exist, try guilt-init
With this variable exported, we have this:
| [INFO] validating against known patches (qemux86-standard-meta)
| error: patch failed: Makefile:2
| error: Makefile: patch does not apply
| To force apply this patch, use 'guilt push -f'

commit 7a79f7412 [linux-yocto: make KBRANCH the exception and not the rule]
ensures that a request branch is always built. The implementation of this
guarantee is a branch switch before the build starts. But that switch may
be before all patches are applied. If the proper routines are not called,
no patches can be applied to the tree.
Updating the SRCREV to pickup this fix:
updateme: use branch command when forcing branch switches
When forcing a branch switch to the desired branch we should be
using the proper 'branch' command. Since without this call, the
proper variables will not be set, and patches can't be applied
to the tree.

To support custom repositories that set a SRCREV and that only have
a single master branch, do_validate_branches needs a special case
for 'master'. We can't delete and recreate the branch, since you
cannot delete the current branch, instead we must reset the branch
to the proper SRCREV.

The kernel branch is no longer required by the yocto-kern-tools
to locate BSP feature descriptions (it is the MACHINE:KTYPE
descriptor), so we no longer require that the BSP branch be
explicitly set.
If a kernel branch is explicitly set, it is now used to trigger
a checks to ensure that the branch really is being built.
Otherwise the branch that the machine description creates will
be built (just as it always was).
This further simplies the use and configuration of a linux-yocto
based kernel recipe.

Updating the kern-tools SRCREV to pick up the following fix:
Out of tree feature descriptions (.scc files) take two forms: normal
features and BSP descriptions.
A normal feature is detected and added to the end of the current machine
being processed. During tree processing, it's configuration and patches
will be applied.
A BSP description on the other hand must be matched based on three
critera (which are in the .scc file via "define <foo>"):
- machine
- kernel type
- architecture
Since features that define machines are only explicitly added, they
are removed from the list of features that should be automatically
added.
The criteria for removing them from the auto-add list is the
definitions found in the .scc file. The existing check was simply
for KMACHINE anywhere in the file. This meant that a conditional
or even a comment containing that phrase would exclude a file.
Properly anchoring the KMACHINE test to "^define.*KMACHINE" fixes the
problem of overly agreesive exclusions.

about branch and directory naming.
There are no user visible changes with this update, but the plumbing

kgit-publish: remove --remote option
The ability to publish and automatically push a repository was
never used, and is error prone. The complexit isn't needed in
the script, so removing it is the best option.
An explicit push after tree publication is suggested, or a
wrapper script (specific to a particular infrastructure) around
this script.

kern-tools: remove unused code, scripts and transition code
The period of supporting old trees with a different meta
branch name and directory structure are gone. So the cleanup
and removal of the old structure can be completed.
The meta branch and directory are now controlled via command line,
or via the KMETA environment variable. No testing and conditional
processing of the tree are required.
Additionally, the generate_cfg script is no longer used, or is the
branch conditing code in createme. So they can be safely removed
from the tools and repository.

kern-tools: remove meta tag and directory assumptions
During repository sanity checks (createme) and during the
checkpoint process, there were several assumptions about the tree
that either relied on a tag, or a particular directory name.
With this set of changes, simply passing the meta branch name is
enough to sanitize and restore the checkpoint. If no meta branch
name is passed, the default of 'meta' is used for both the branch
and meta data directory name.

The linux-yocto repository and scripts can support a mode of
meta data management that merges a base meta branch to every
BSP branch. In this case, the scripts don't have to restore
a checkpoint for the meta data to be globally accessible.
The decision to restore or not is made based on whether or
not the meta branch is part of all branches or not.
The linux-yocto recipes have a sanity check to determine if
the requested SRCREV for meta data matches the head of the
meta branch (via do_validate_branches). If the wrong commit
is at the head, the meta branch is moved aside and the branch
reset to the right commit. This creates two meta branches that
contain the base meta data.
The test for integrated meta data mistakes this for a globally
merged set of meta data and doesn't restore the checkpoint, which
leads to build failures.
The immediate fix is to allow two branches to have the meta
data. The long term fix is to make the detection only consider
if the build branch contains the meta data.

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
of the variables that were added to support different repository
types.
