comment "linux-backports needs a Linux kernel to be built"
depends on !BR2_LINUX_KERNEL
config BR2_PACKAGE_LINUX_BACKPORTS
bool "linux-backports"
depends on BR2_LINUX_KERNEL
help
The linux-backports package includes many Linux drivers from
recent kernels, backported to older ones.
This version of linux-backports supports kernels starting
from 3.10.

Name of the backports defconfig file to use, without the
leading defconfig-. The defconfig is located in defconfigs/
directory in the backports tree.

Path to the backports configuration file
Note: this can be a defconfig file or a complete .config
file, which can later be saved back with make
linux-update-(def)config.
config BR2_PACKAGE_LINUX_BACKPORTS_CONFIG_FRAGMENT_FILES
string "Additional configuration fragment files"
help
A space-separated list of configuration fragment files, that
will be merged to the main linux-backports configuration file.

# linux-backports' own .config file needs options from the kernel's own
# .config file. The dependencies handling in the infrastructure does not
# allow to express this kind of dependencies. Besides, linux.mk might
# not have been parsed yet, so the Linux build dir LINUX_DIR is not yet
# known. Thus, we use a "secondary expansion" so the rule is re-evaluated
# after all Makefiles are parsed, and thus at that time we will have the
# LINUX_DIR variable set to the proper value. Moreover, since linux-4.19,
# the kernel's build system internally touches its .config file, so we
# can't use it as a stamp file. We use the LINUX_KCONFIG_STAMP_DOTCONFIG
# instead.
#
# Furthermore, we want to check the kernel version, since linux-backports
# only supports kernels >= 3.10. To avoid overriding linux-backports'
# KCONFIG_STAMP_DOTCONFIG rule defined in the kconfig-package infra, we
# use an intermediate stamp-file.
#
# Finally, it must also come after the call to kconfig-package, so we get
# LINUX_BACKPORTS_DIR properly defined (because the target part of the
# rule is not re-evaluated).
