DeOS

Process Streams

• posix+
• stdin

Architectural Notes

• resources
  • kernel
    • entire
  • processes
    • proc 0 - kernel/init or whatever
      • granted full access to process/memory/disk
    • proc 1 - disk
  • disk chunks by user and process/app
• boot process
  • bootloader maps memory and switches to 64 bit
  • kernel remaps memory (probably)

program: executable
application: role of program
user app: applications tied together

Practical Example

• acme_doohicky program with file_select application
• cyberdyne_foo program with editor application
• user creates MyEditor program by tying the two applications together
