* kernel-yocto: allow building from fetcher source dirBruce Ashfield2013-03-011-17/+22
| | | | | | | | | | | | | | | | | | | | | | | 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).

* kernel-yocto: respect SRC_URI modified branch selectionBruce Ashfield2013-03-011-32/+38
| | | | | | | | | | | | | | | | | | | | | | | | 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 (From OE-Core rev: cfce8643ed166b51d7178be173677ea6f527d453) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel-yocto/linux-yocto-custom: support low bandwidth optionsBruce Ashfield2013-02-041-13/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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" [YOCTO #2686] (From OE-Core rev: 08b3a282ce75a9972694f0c4379179505b9ec91f) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel-yocto: allow multiple / shared kernel feature directoriesBruce Ashfield2013-02-041-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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}" (From OE-Core rev: 02ad603a104b70ab74548c8018e738bfbb3c59db) Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel-yocto: fix .scc and .cfg matchingBruce Ashfield2013-02-041-1/+1
| | | | | | | | | | | | | | SRC_URIs that contained git repositories or other constructs that resulted in an extension of "." or a substring of "scc" or "cfg" were matching the tests for patches and configs. This was due to a python tuple being used instead of an array. Switching to an array makes the match exact and the behaviour we want.

| | | | | | | | | | | | Since linux-yocto based recipes have a split build and source directory, we should export KBUILD=${B} to the devshell.

* kernel-yocto: checkout known branch before leaving do_validate_branchesBruce Ashfield2012-12-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* kernel-yocto: clarify KMETA branch commentsBruce Ashfield2012-11-221-2/+3
| | | | | | | | | | | | | | | | | | | | 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. # If KMETA is defined, the branch must exist, but a machine branch # can be missing since it may be created later by the tools.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* linux-yocto: check for bad SRCREV before branch checksBruce Ashfield2012-09-041-7/+8
| | | | | | | | | | | | | | | | | | 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 be built (just as it always was). This further simplies the use and configuration of a linux-yocto based kernel recipe.

* linux-yocto: allow .cfg, .scc, .patch and defconfigs to be processed in orderBruce Ashfield2012-04-131-67/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* linux-yocto: improve checkout error handling and reportingBruce Ashfield2012-02-241-23/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The results are then fed to the existing infrastructure to be applied and commited to the tree.

| | | | | | | | | | | | | | | | | | | | When creating a minimal config or creating a hard baseline for incremental changes, it is often desired to disable all kernel options and then begin building and enabling only what is required. To support this workflow, a new variable KCONFIG_MODE is introduced to contain a hint to the kernel configuration about how the kernel config should be produced. This variable is passed directly to lkc when it is invoked during configuration, so the contents of the variable must be a valid option for the kernel config build. Additionally, when a defconfig is detected, allnoconfig is enabled as the default operation, unless otherwise specified by KCONFIG_MODE.

| | | | | | | | | | | | | | | | | | | | | 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.

* kernel: copy defconfig to {B} vs {S}Bruce Ashfield2011-07-221-6/+0
| | | | | | | | | | | | | | | | | | | | | | | 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.
