te doen:
|
|
- caps in init met een cap per process
|
|
- die cap bevat caps in target memory met een cap per service
|
|
- die cap bevat een user van de service
|
|
- sysreq is geen aangeboden service, usbfs wel
|
|
- sysreq schakelt tussen running processes incl. user switching.

- display interface: put pixel commando

|
- typewriter: print toetsen op scherm; shell?

- emulaties automatisch per proces

|
- start programma van filesystem
|
|
- nand driver
|
|
- filesystems met backing store
|
|
|
|
Boot process:
|
|
- bootinit and filesystem (and backing store) are started.
|
|
- bootinit starts run.elf and loads init.elf.
|
|
- run starts init.
|
|
- init loads init.config and executes it.
|
|
- during that process, the initial programs are killed.
|
|
|
|
Order:
|
|
run.elf

init.elf

init.config
