- README
- ======
- This directory provides support for the two-pass build. Its primary
- purpose is to incorporate source logic generated by applications into the
- kernel phase of the build.
- In the two pass build, the application logic is built during the first
- phase, pass 1. In that phase, the application may generate and install
- source files into the pass1/ directory.
- The operating system is built during phase 2 of the build. At that time,
- those source files in the pass1/ directory will be built and incorporated
- into the kernel address space.
- The primary purpose of the pass1/ directory is to such application-
- generated kernel symbol tables. For an example of the use of this
- feature, look at apps/examples/module/drivers/Makefile. Kernel symbol
- tables are needed to support kernel modules.
- Of course, addition board-specific logic in, say, at
- boards/<arch>/<chip>/<board>/src would have to be included to make use of
- the application-installed symbol tables.
