* kernel: drop unnecessary True options from calls to getVarAndre McCurdy2018-01-191-3/+3
| | | | | | | | | | | | | | The older style calls (plus a bashism in kernel.bbclass, fixed separately) were introduced via the recent change to add support for multiple kernel packages: http://git.openembedded.org/openembedded-core/commit/?id=6c8c899849d101fd1b86aad0b8eed05c7c785924 (From OE-Core rev: e660ef68de3b3891a26ed6e10d96dc4efaf03ffc) Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* kernel: Add support for multiple kernel packagesHaris Okanovic2018-01-021-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some distros may want to provide alternate kernel "flavors" via feeds or within bootable images. For example, readily available builds which provide certain diagnostic features can enable developers and testers to more quickly resolve issues by avoiding lengthy kernel builds. This change allows for building multiple flavors of the kernel and module packages by templatizing kernel package names via a new KERNEL_PACKAGE_NAME variable in kernel.bbclass. It defaults to the old name of "kernel", but can be overridden by certain recipes providing alternate kernel flavors. To maintain compatibility, recipes providing alternate kernel flavors cannot be the "preferred provider" for virtual/kernel. This is because OE puts the preferred provider's build and source at "tmp-glibc/work-shared/$MACHINE/kernel-build-artifacts/" and "tmp-glibc/work-shared/$MACHINE/kernel-source/" instead of "tmp-glibc/work/*/$PN/" like other recipes. Therefore, recipes using the default KERNEL_PACKAGE_NAME="kernel" follows the old semantics -- build in the old location and may be preferred provider -- while recipes using all other KERNEL_PACKAGE_NAME's build from the normal WORKDIR and don't provide "virtual/kernel". Testing: 1. Add `KERNEL_PACKAGE_NAME_pn-linux-yocto-tiny = "tiny-linux"` to local.conf so that linux-yocto-tiny may build alongside the main kernel (linux-yocto). 2. `bitbake linux-yocto linux-yocto-tiny` to build both kernel flavors. 3. Verified image and modules IPKs exist for both: tmp-glibc/deploy/ipk/qemux86/kernel-* for linux-yocto tmp-glibc/deploy/ipk/qemux86/tiny-linux* for linux-yocto-tiny 4. Verified linux-yocto is the "preferred provider", and was built in shared directory: tmp-glibc/work-shared/qemux86/kernel-* 5. Add `CORE_IMAGE_BASE_INSTALL_append_pn-core-image-base = "tiny-linux"` to local.conf to install both kernel flavors in core-image-base. 6. `bitbake core-image-base` to build an image. 7. Verified image contains two bzImage's under /boot/, with "yocto-standard" (linux-yocto recipe) selected to boot via symlink.

* Revert "kernel-module-split: rrecommend kernel-image instead of rdepend"Martin Hundebøll2017-09-121-6/+1
| | | | | | | | | | | | | | | | | This reverts commit e0ed52c51464855e9a6a37ea49df7efde7e91076. Commit e0ed52c514 ('kernel-module-split: rrecommend kernel-image instead of rdepend') changed kernel modules to rrecommend kernel-image instead of rdepend on kernel. This broke existing setups, where the kernel is omitted by setting RDEPEND_kernel-base = "". Revert the patch, as the existing way of omitting kernel-image in images works just fine.

* kernel-module-split: rrecommend kernel-image instead of rdependMartin Hundebøll2017-08-231-1/+6
| | | | | | | | | | | | | | | | Hard depending on the kernel makes it impossible to install kernel modules without getting the kernel image installed too. This is inconvenient in e.g. initramdisks, where the kernel is loaded from outside the initramdisk. Making the kernel modules rrecommend kernel-image-<version> instead of rdepending on it, makes it possible to install kernel modules without the kernel image by setting "kernel-image" in BAD_RECOMMENDATIONS.

* kernel-module-split: Append KERNEL_VERSION string to kernel module nameOla Redell2017-01-191-1/+8
| | | | | | | | | | | | | | | | | | | | The KERNEL_VERSION string is added to kernel module package names in order to make the kernel modules for different kernel versions distinct packages instead of different versions of the same package. With this change, when a new kernel is installed together with its kernel modules (e.g. by upgrade of the packages kernel and kernel-modules) using some package manager such as apt-get or rpm, the kernel modules for the older kernel will not be removed. This enables a fall back to the older kernel if the new one fails. Also, for backwards compatibility and to enable kernel version agnostic dependencies to kernel modules, create a virtual package with the old (shorter) kernel module package name using RPROVIDES.

| | | | | | | | | | | | | | | | | | | | | | | | The information retrieved via depmod is incomplete with regards to kernel modules that are dependencies, in particular where two kernel modules are built from different source trees / recipes, which leads to incomplete dependency information for packages created. So far, our packages created didn't contain dependencies on packages created by other recipes, as we solely use depmod for that, and depmod can only work well after *all* kernel modules have been copied into one place - it doesn't work well in a staged approach. Now that all .ko have correct dependency information at packaging time, we can use that information to properly track dependencies across recipies, and can combine the information from the .modinfo elf section with the information from depmod.

* kernel-module-split.bbclass: add a prefix for module package name patternRicardo Neri2016-07-011-1/+5
| | | | | | | | | | | | | | | | | | | | | | When splitting kernel modules into individual packages, such packages take their names from the module name. This is OK under most of the circumstances. However, it may lead to package naming collisions if there exists two modules with the same name. Situations like this can occur when building testing modules. For instance, there exists testing versions of the modules for non-volatile memory that are built with different linker options but bear the same module name. If one wants to package such modules, it is be good to be able to name packages differently. This can be done by prefixing the package name with a KERNEL_MODULE_PACKAGE_PREFIX that can be set by the recipes that inherit from module.bbclass.

The problem is that the System.map and kernel-abiversion files are needed for depmod and after the recent kernel changes, these are no longer in sstate. Its reasonable to require the kernel to unpack/build if you're about to build a module against it. It is not reasonable to require this just to build a rootfs. Therefore stash the needed files specifically for depmod. Also fix some STAGING_KERNEL_DIR references which were incorrect, found whilst sorting through his change.

* kernel: move source and build output to work-sharedBruce Ashfield2015-01-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 3b3f7e785e279 [kernel: Rearrange for 1.8] began the process of moving the kernel source and build artefacts out of sstate control and into a shared location. This changed triggered some workflow issues, as well as bugs related to the kernel source containing build output, and hence being dirty and breaking kernel rebuilds. To solve these issues, and to make it clear that the kernel is not under sstate control, we move the source and build outputs to: work-shared/MACHINE/kernel-source work-shared/MACHINE/kernel-build-artifacts Where kernel-build-artifacts is the kernel build output and kernel-source is kept "pristine". The build-artifacts contain everything that is required to build external modules against the kernel source, and includes the defconfig, the kernel-abiversion, System.map files and output from "make scripts". External module builds should either pass O= on the command line, or set KBUILD_OUTPUT to point to the build-artifacts. module-base.bbclass takes care of setting KBUILD_OUTPUT, so most existing external module recipes are transparently adapted to the new source/build layout. recipes that depend on the kernel source must have a depedency on the do_shared_workdir task: do_configure[depends] += "virtual/kernel:do_shared_workdir" With this dependency added, the STAGING_KERNEL_DIR will be populated and available to the rest of the build.
