* module.bbclass: use Module.symvers for dependantsAndré Draszik2016-09-091-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When compiling multiple external kernel modules, where one depends on the other, there are two problems at the moment: 1) we get compile time warnings from the kernel build system due to missing symbols (from modpost). 2) Any modules generated are missing dependency information (in the .modinfo elf section) for any dependencies outside the current source tree and outside the kernel itself. This is expected, but the kernel build system has a way to deal with this - the dependent module is expected to specify KBUILD_EXTRA_SYMBOLS (as a space-separated list) to point to any and all Module.symvers of kernel modules that are dependencies. While 1) by itself is not really a big issue, 2) prevents the packaging process from generating cross-source tree package dependencies. As a first step to solve the missing dependencies in packages created, we: 1) install Module.symvers of all external kernel module builds (into a location that is automatically packaged into the -dev package) 2) make use of KBUILD_EXTRA_SYMBOLS and pass the location of all Module.symvers of all kernel-module-* packages we depend on This solves both problems mentioned above.

* classes/module: allow substitution of the modules_install target namePaul Eggleton2016-03-021-1/+3
| | | | | | | | | | | | | | | Quite a few external kernel modules I've found floating around don't have a modules_install target, but they do have an install target that basically differs only in name. To make it easier to build these just make this a MODULES_INSTALL_TARGET variable that you can set from the recipe - the alternative would be copy-and-paste the do_install definition from this class which is potentially fragile.

* module/module-base/lttng-modules: Improve kernel module dependenciesRichard Purdie2015-05-141-3/+1
| | | | | | | | | | | | | | | | | If we have DEPENDS = "virtual/kernel" is means that the kernel module depends on the kernel's do_populate_sysroot task. This is not entirely desireable since that depends on do_install which depends on do_compile_kernelmodules and so on. In a situation where rm_work in involved this can cause some pretty length build cycles after the kernel workdir has been cleaned up by rm_work. As well as removing this, take the opportunity to clean up duplicated dependency lines, tweak the dependency of make_scripts for the same reason and generally try and make things more readable.

* kernel: move source and build output to work-sharedBruce Ashfield2015-01-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | Previously the build path to STAGING_KERNEL_DIR was being embedded into the package post install scripts. We avoid this behavior by generating a special depmodwrapper script.

| | | | | | | | | | | | | | | | | | The update-modules mechanism is something of a historical relic and it isn't entirely clear that it has a great deal of value nowadays. Also, it causes a problem when building a read-only rootfs since update-modules itself refuses to configure offline. Allow DISTROs to circumvent this whole thing by declaring (via DISTRO_FEATURES) that they don't wish to use update-modules. This is backfilled for existing distributions and will have to be marked as CONSIDERED by those who actually don't want it.

* {kernel, module}.bbclass: don't run depmod for module packages during do_rootfsAndreas Oberritter2012-04-261-4/+3
| | | | | | | | | | | | | | | | | * depmod already gets executed by pkg_postinst_kernel-image. * If you build a module using module.bbclass, pkg_postinst returns 1 in do_rootfs, causing pkg_postinst to run again on first boot. To improve this situation, I copied pkg_postinst from kernel.bbclass to module.bbclass. This was rejected by Koen, because he doesn't like the code from kernel.bblcass, which uses ${STAGING_DIR_KERNEL}. Richard then suggested that calling depmod during do_rootfs wasn't necessary at all, because it already gets done by kernel-image.

* kernel/bbclass: rework kernel and module classes to allow for building ↵Darren Hart2011-03-231-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | out-of-tree modules The existing infrastructure uses an external build tree which references the kernel source in the work dir. If run with rm work, building external modules will fail. This patch places a configured source tree in sysroots. Striking a balance between minimal size and minimal maintenance is difficult. A fully configured tree is about 500MB after a clean. This version leans on the side of caution and removes only the obviously unecessary parts of the source tree to conserve space, resulting in about 170MB. The arch directories would be some additional pruning we could do. Given examples from the devel package from distributions, I suspect this size could be reduced to 75MB or so, but at the cost of a much more complex recipe which is likely to require a great deal more maintenance to keep current with kernel releases. Care is also taken to clean the hostprogs in scripts, and the modules are responsible for building them as needed. Although it is unclear to me if this is really necessary, especially considering that modules put these bits back as soon as they compile. If we are not generating an sstate package, I suspect we can ignore these. Please try this with your modules and let me know how it does. I tried to take non linux-yocto kernel recipes into account, but I have only tested with linux-yocto and the hello-mod recipe so far.

* module: build hostprogs for each moduleDarren Hart2011-03-041-1/+11
| | | | | | | | | | | | | | | | | | | | | This fixes [BUGID #241] The kernel hostprogs are built for the host architecture. They should not be deployed to the target, and they should not be included in an sstate package which might get reused on a host of a different architecture. As we don't build many out-of-tree modules, this patch takes the approach of building the hostprogs as part of the module compile process with a do_compile_prepend() routine in module.bbclass. We don't have to clean the hostprogs as modules depend on the kernel being populate_staging, so its done with the staging directory by the time we run.
