[Buildroot] Buildroot and kernel modules

[Sid Bharij]

Thank you gentlemen!
So I have the driver source file and makefile for it.
Where does this part go into ? Does it go into the Config.in file or some
top level makefile or the same makefile needed for compiling the driver
code?

KERNELMODULE_DEPENDENCIES = linux

define KERNELMODULE_BUILD_CMDS
   $(MAKE) $(LINUX_MAKE_FLAGS) -C $(LINUX_DIR) M=$(@D) modules
endef

define KERNELMODULE_INSTALL_TARGET_
CMDS
   $(MAKE) $(LINUX_MAKE_FLAGS) -C $(LINUX_DIR) M=$(@D) modules_install
endef

$(eval $(generic-package))
