Hello, I have spend some time analysing KBuild source files. However there is one thing that is not clear for me. In the main makefile I have found the following statement: Most importantly: sub-Makefiles should only ever modify files in their own directory. If in some directory we have a dependency on a file in another dir (which doesn't happen often, but it's often unavoidable when linking the built-in.o targets which finally turn into vmlinux), we will call a sub make in that other dir, and after that we are sure that everything which is in that other dir is now up to date. Kernel is build in a recursive manner. I understand that according to the citation firstly all dependencies between different directories are identified and then the sub-directory walk through process is started. Unfortunately I cannot fine where this functionality is implemented? Can somebody point me the right place or maybe my line of reasoning is simply wrong?
