Abstract
SeL4 is the newest member of the L4 microkernel family. It is also the world’s first (currently the only one) general-purpose operating system which has passed the formal verification. However, as the micro-kernel system, seL4 currently provided little library function interface. RefOS is a typical multi-tasking operating system which built on seL4. This paper achieves the mmap function, providing memory mapping and sharing, as well as process copy which is similar with the fork function on RefOS. The child process can share the memory region which is marked as SHARED by mmap with its parent process. Our job provides support for implementing the POSIX standard interfaces on RefOS, as well as a lower-level interface for the development of parallel programs.
