  • How do userspace programs "obtain access" to device memory? Needed for drivers
  • How do userspace programs communicate? Which communication mechanisms should be provided by the kernel?
  • How do userspace programs "transfer access" or "share access" with other programs? e.g. a display server has allocated a memory region for a window's surface and wants to share it with the client.
  • How will read()/write()/other FS primitive calls be implemented?
  • What information/access does the init program obtain from the kernel?
