2016-09-08kernel-module-split.bbclass: no need for running depmodAndré Draszik
With the recent changes, executing depmod is not needed anymore. This simplifies and removes a lot of unnecessary code. Signed-off-by: André Draszik <git@andred.net> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2016-09-08kernel-module-split.bbclass: generate dependencies across recipesAndré Draszik
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.

2016-07-01kernel-module-split.bbclass: add a prefix for module package name patternRicardo Neri
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.

2015-03-24kernel-module-split.bbclass: fix autoloading from postinst scriptAndreas Oberritter
When using KERNEL_MODULE_AUTOLOAD, autoload was empty, causing "modprobe None" to get appended to the postinst script. Signed-off-by: Andreas Oberritter <obi@opendreambox.org> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2015-01-23kernel/image/depmodwrapper: Fixups for depmodRichard Purdie
With the rpm package backend enabled, running: bitbake <image> bitbake virtual/kernel -c clean bitbake <image> -c rootfs -f results in an image with incorrect kernel module dependency information. 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.

2015-01-16kernel: move source and build output to work-sharedBruce Ashfield
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.

2014-07-23kernel-module-split.bbclass: Allow autoloading multiple modules or modules ↵Martin Jansa
where basename != module name * new KERNEL_MODULE_AUTOLOAD syntax doesn't support modules where basename and module name don't match (usually - and _), e.g.: module_autoload_bq27x00_battery = "bq27x00-battery" * sometimes it's useful to load modules in particular order and module_autoload allowed to just list multiple modules, e.g.: module_autoload_snd-soc-neo1973-wm8753 = "snd-soc-s3c24xx snd_soc_s3c24xx_i2s snd-soc-dfbmcs320 snd-soc-wm8753 snd-soc-neo1973-wm8753" or module_autoload_g_ether = "s3c2410_udc g_ether" restore this possibility which is useful for incorrect dependencies between modules Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2014-06-16kernel-module-split: Add support for KERNEL_MODULE_AUTOLOAD and ↵Richard Purdie
KERNEL_MODULE_PROBECONF The current module_autoload_* and module_conf_* variables are error both ugly and error prone. They aren't registered in the task checksums so changes to them aren't reflected in the build. This turns out to be near impossible to fix with the current variable format in any sensible way :(. This patch replace module_autoload with the list of variables in KERNEL_MODULE_AUTOLOAD which is a much simpler and usable API. An error is printed if an old style variable is encountered. It should be simple to convert to this. module_conf_* are harder to deal with since there is data associated with it, it isn't simply a flag. We need a list of variables that are set in order to be able to correctly handle the task checksum so we add KERNEL_MODULE_PROBECONF for this purpose and error if the user hasn't added a module to it when they should have.
