techpack: add tech package support Enable tech packages to have kernel drivers that are physically located in the kernel source tree but not present in the kernel repository. This is done via a manifest line item to fetch a techpackage-module into $KERNEL/techpack/$techpackage-module. $KERNEL/techpack/Kbuild will automatically detect any subdirectories and link them to the kernel's kbuild system. The resulting layout of techpack within kernel source would be as follows :- kernel/ ├── techpack/ ├── Kbuild └── stub │ ├── Makefile │ ├── include │ │ └── uapi │ │ └── Kbuild └── stub.c ├── techpackage-module ├── Makefile ├── include │ └── uapi │ ├── Kbuild $KERNEL/techpack only contains Kbuild (no Makefile) at the toplevel and this Kbuild takes care of both compiling the subdirectories and of exporting the needed header files therein. The reason for having only Kbuild at the top is that Kbuild and Makefile cannot exist together in same directory and Makefile doesn't cater to uapi header installation. stub is an empty techpackage-module which serves both as a sample layout and satisfies the requirement of kernel build system, by providing necessary buit-in.o, when no other techpackage-module has been pulled under techpack/. $KERNEL/techpack/techpackage-module should have a Makefile at the top and Kbuild under $KERNEL/techpack/techpackage-module/include/uapi directory. The uapi headers pertaining to a techpackage-module should reside under $KERNEL/techpack/techpackage-module/include/uapi and associated Kbuild should have necessary rules to export it.
