# 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, copy this recipe (optionally
# rename it as well) and modify it appropriately for your machine. i.e.:
#
# 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 copy (and rename) of this recipe 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 v4.x only):
# SRC_URI += "file://0001-linux-version-tweak.patch"
# example feature addition (for kernel v4.x only):
# SRC_URI += "file://feature.scc"
