# This builds the supported LinuxKit kernels. Kernels are wrapped up
|
|
# in a minimal toybox container, which contains the bzImage, a tar
|
|
# ball with modules and the kernel source.
|
|
#
|
|
# Each kernel is pushed to hub twice, once as
|
|
# linuxkit/kernel:<kernel>.<major>.<minor>-<hash> and once as
|
|
# inuxkit/kernel:<kernel>.<major>.x. The <hash> is the git tree hash
|
|
# of the current directory. The build will only rebuild the kernel
|
|
# image if the git tree hash changed.
|
|
|
|
# Git tree hash of this directory. Override to force build
|
|

# A template for defining kernel build
|
|
# Arguments:
|
|
# $1: Full kernel version, e.g., 4.9.22
|
|
# $2: Kernel "series", e.g., 4.9.x
|
|
# $3: Build a debug kernel (used as suffix for image)
|
|
# This defines targets like:
|
|
# build_4.9.x, push_4.9.x and sign_4.9.x and adds them as dependencies
|
|
# to the global targets
|
|
# Set $3 to "_dbg", to build debug kernels. This defines targets like
|
|
# build_4.9.x_dbg and adds "_dbg" to the hub image name.
