Userspace often breaks as we change the capability structure. Now structure is under api/ so userspace can also update with changes.
Codezero POSIX Services This directory contains the source code for the POSIX services developed on top of the Codezero Microkernel. There is a pager called MM0 which demonstrates how a pager on top of Codezero should act, by its system call usage. Test0 is the userspace task that tests microkernel system call functionality as well as the POSIX system call functionality by issuing calls to MM0 Codezero POSIX services partially demonstrate how a POSIX level operating system would be written on top of Codezero. Unlike shallow implementations on embedded systems that only look like POSIX, mm0 implements a real virtual memory subsystem and virtual filesystem that solidly backs the API. Neverhtheless services such as terminal IO and common filesystem support are currently missing.
