### KERNEL SETUP
### Setup the stuff needed for making kernel module packages
### taken from /usr/share/kernel-package/sample.module.rules

# prefix of the target package name
PACKAGE=oss4-modules
# modifieable for experiments or debugging m-a
MA_DIR ?= /usr/share/modass
# load generic variable handling
-include $(MA_DIR)/include/generic.make
# load default rules, including kdist, kdist_image, ...
-include $(MA_DIR)/include/common-rules.make

# module assistant calculates all needed things for us and sets
# following variables:
# KSRC (kernel source directory), KVERS (kernel version string), KDREV
# (revision of the Debian kernel-image package), CC (the correct
# compiler), VERSION (the final package version string), PKGNAME (full
# package name with KVERS included), DEB_DESTDIR (path to store DEBs)

# The kdist_configure target is called by make-kpkg modules_config and
# by kdist* rules by dependency. It should configure the module so it is
# ready for compilation (mostly useful for calling configure).
# prep-deb-files from module-assistant creates the neccessary debian/ files 
kdist_config kdist_configure: prep-deb-files

# the kdist_clean target is called by make-kpkg modules_clean and from
# kdist* rules. It is responsible for cleaning up any changes that have
# been made by the other kdist_commands (except for the .deb files created)
kdist_clean:
	cd core && rm -f *.o *.ko *.mod.c *.mod.o .*.cmd modules.order Module.symvers limits.h && rm -rf .tmp_versions && cd ..
	cd drivers && rm -f *.o *.ko *.mod.c *.mod.o .*.cmd modules.order osscore_symbols.inc && rm -rf .tmp_versions && cd ..
#	rm -f driver/*.o driver/*.ko
