# linux-yocto-custom.bb: # # An example kernel recipe that uses the linux-yocto and oe-core # kernel classes to apply a subset of yocto kernel management to git # managed kernel repositories. # # To use linux-yocto-custom in your layer, create a # linux-yocto-custom.bbappend file containing at least the following # lines: # # FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:" # COMPATIBLE_MACHINE_yourmachine = "yourmachine" # # You must also provide a Linux kernel configuration. The most direct # method is to copy your .config to files/defconfig in your layer, # in the same directory as the bbappend and add file://defconfig to # your SRC_URI. # # To use the yocto kernel tooling to generate a BSP configuration # using modular configuration fragments, see the yocto-bsp and # yocto-kernel tools documentation. # # Warning: # # Building this example without providing a defconfig or BSP # configuration will result in build or boot errors. This is not a # bug. # # # Notes: # # patches: patches can be merged into to the source git tree itself, # added via the SRC_URI, or controlled via a BSP # configuration. # # defconfig: When a defconfig is provided, the linux-yocto configuration # uses the filename as a trigger to use a 'allnoconfig' baseline # before merging the defconfig into the build. # # If the defconfig file was created with make_savedefconfig, # not all options are specified, and should be restored with their # defaults, not set to 'n'. To properly expand a defconfig like # this, specify: KCONFIG_MODE="--alldefconfig" in the kernel # recipe. # # example configuration addition: # SRC_URI += "file://smp.cfg" # example patch addition (for kernel v3.4 only): # SRC_URI += "file://0001-linux-version-tweak.patch # example feature addition (for kernel v3.4 only): # SRC_URI += "file://feature.scc" # inherit kernel require recipes-kernel/linux/linux-yocto.inc # Override SRC_URI in a bbappend file to point at a different source # tree if you do not want to build from Linus' tree.
