The kernel plugin
kernel plugin adds to the configuration options provided by the generic kbuild plugin to help build kernel snaps.
The API for this plugin is currently is unstable, and cross-compiling support is consequently classed as experimental.
This plugin uses the common plugin keywords as well as those for “sources”. For more information, see Snapcraft parts metadata.
The following kernel specific options are provided by this plugin:
kernel-image-target(yaml object, string or null for default target)
The default target is bzImage and can be set to any specific target.
For more complex cases where one would want to use the same snapcraft.yaml to target multiple architectures, a yaml object can be used.
This yaml object would be a map of Debian architecture and kernel image build targets.
kernel-initrd-modules(array of string)
List of modules to include in initrd. Note: kernel snaps do not provide the core boot logic which comes from snappy Ubuntu Core OS snap.
Include all modules you need for mounting rootfs here.
kernel-with-firmware(boolean; default: True)
Use this flag to disable shipping binary firmwares.
kernel-initrd-firmware(array of string)
List of firmware files to include in the initrd; these need to be relative paths to
This option does not work if you disable building firmware.
kernel-initrd-compression(string; default: gz)
Initrd compression to use. The only supported value is now
kernel-device-trees(array of string)
List of device trees to build. The format is
