42 # This top-level kbuild makefile builds all the Linux kernel modules in the
43 # DDK. To run kbuild, this makefile is copied to $(TARGET_PRIMARY_OUT)/kbuild/Makefile
44 # and make is invoked in $(TARGET_PRIMARY_OUT)/kbuild.
46 # This makefile doesn't define any kbuild special variables apart from
47 # ccflags-y and obj-m. The variables for objects are picked up by including
48 # the kbuild makefile fragments named in $(INTERNAL_KBUILD_MAKEFILES). The
49 # list of objects that these fragments make is collected in
50 # $(INTERNAL_KBUILD_OBJECTS) and $(INTERNAL_EXTRA_KBUILD_OBJECTS). These
51 # variables are set according to the build's $(KERNEL_COMPONENTS) and
52 # $(EXTRA_PVRSRVKM_COMPONENTS). To add a new kernel module to the build, edit
53 # these variables in the per-build Makefile.
