linux/poky.git/meta/classes-recipe/kernel-module-split.bbclass, branch master

The poky repository master branch is no longer being updated.

2025-11-07T13:31:53+00:00

You can either: a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs b) use the new bitbake-setup You can find information about either approach in our documentation: https://docs.yoctoproject.org/ Note that "poky" the distro setting is still available in meta-yocto as before and we continue to use and maintain that. Long live Poky! Some further information on the background of this change can be found in: https://lists.openembedded.org/g/openembedded-architecture/message/2179 Signed-off-by: Richard Purdie

kernel-module-split: fix conf file generation when KERNEL_SPLIT_MODULES=0

2025-06-12T10:03:43+00:00

KERNEL_MODULE_AUTOLOAD defines the list of the kernel modules to be autoloaded on boot. kernel-module-split.bbclass generates the required modules.load.d and conf files for each kernel module. This conf files inturn read by system service to perform module loading and configuration. When a kernel module is added to KERNEL_MODULE_AUTOLOAD the conf files must be generated in all cases. When KERNEL_SPLIT_MODULES=0 modprobe and autoload conf files are not getting generated for the kernel modules. To fix that enhanced the class implementation by separating out conf file handling mechanism in two functions, generate_conf_files() and frob_metadata(). generate_conf_files() handles no-split case where as frob_metadata() keeps handling the existing case for spliting the modules. Splitted common handling/generation of conf files stuff in to handle_conf_files() function which gets invoked by both frob_metadata() and generate_conf_files() on top of the scenario specific handling done in respective functions. This implementation covers generation of the conf files for in-tree kernel modules as well as standalone kernel module built as seperate package/recipe.

kernel-module-split: Allow for external conf files

2025-05-20T13:47:50+00:00

Some recipes might provide conf files produced during build phase or simply tracked in the VCS instead of generating them with Yocto. In such cases those conf files wouldn't be assigned to correct packages. With this change, if user wants to generate a conf file they still can, but not generating them won't prevent assigning the file to proper package given the file exists.

kernel-module-split.bbclass: enhance objcopy command call for kernel compilation with llvm

2024-03-26T17:10:51+00:00

Using meta-clang for llvm kernel compilation previously defaulted to the gcc objcopy tool. To improve flexibility and compatibility, $OBJCOPY is preferred over $HOST_PREFIXobjcopy in the kernel-module-split.bbclass. With $OBJCOPY already defined in bitbake.conf, the empty condition has been removed, simplifying the invocation process.

kernel-module-split add systemd modulesloaddir and modprobedir config

2023-07-10T10:36:34+00:00

Because busybox doesn't support other path than /etc [1] we can't change the default path unconditionally so change it only for systemd. The modules-load.d [2] - Configure kernel modules to load at boot should install their configuration files in /usr/lib/modules-load.d. The modprobe.d [3] - Configuration directory for modprobe should install their configuration files in /lib/modprobe.d [1] https://git.busybox.net/busybox/tree/modutils/modprobe.c?id=669c40ed8ebf480c95ce36135104e474e361a7e6#n658 [2] https://man7.org/linux/man-pages/man5/modules-load.d.5.html [3] https://man7.org/linux/man-pages/man5/modprobe.d.5.html [YOCTO #12212] https://bugzilla.yoctoproject.org/show_bug.cgi?id=12212 (From OE-Core rev: 075c309bd28bc8e19a82569a2e75da14fa5795dd) Signed-off-by: Jose Quaresma Signed-off-by: Richard Purdie

kernel-module-split: install config modules directories only when they are needed

2023-06-28T22:17:13+00:00

Instaed of allways create the directories and removing it at the if they are not used, we can just do it when there are modules configuration to be created. So the best thing to do is install the directories only when necessary. (From OE-Core rev: 71460993f350bca3d5a22115fd5551696f955c9f) Signed-off-by: Jose Quaresma Signed-off-by: Richard Purdie

recipes, classes: Avoid adding extra whitespace to PACKAGESPLITFUNCS

2023-01-12T23:08:58+00:00

This is a follow-up to commit 846ff49465 to remove the extra whitespace that is no longer needed after converting :append and :prepend to += and =+.

recipes/classes: Drop prepend/append usage with PACKAGESPLITFUNCS

2023-01-05T11:52:50+00:00

As far as I can tell, none of these uses of PACKAGESPLITFUNCS need append/prepend operators, the standard += and =+ can work just fine. Since OE-Core is copied a lot, use the preferred syntax which is also simpler to parse and change. (From OE-Core rev: 846ff49465337dddd75a83161f41f48117f6571c) Signed-off-by: Richard Purdie
