# AbleOS
|
||||
## General
|
||||
- [ ] Improve EXT2
|
||||
- [ ] Remove x86 specific code and refine the boot process
|
||||
|
||||
## Capabilities
|
||||
A new process should not have any capabilities at all until it is given them or requests them and is approved.
|
||||
- [ ] Filesystem cap
|
||||
- [ ] Create a new filesystem
|
||||
- [ ] Unmount/Mount a filesystem
|
||||
- [ ] read a file
|
||||
- [ ] write a file
|
||||
- [ ] delete a file
|
||||
|
||||
- [ ] Network cap
|
||||
- [ ] open/close socket
|
||||
- [ ] bind/unbind socket
|
||||
|
||||
- [ ] Manage Process cap
|
||||
- [ ] spawn Process cap
|
||||
- [ ] kill Process cap
|
||||
|
||||
## Riscv
|
||||
|
||||
## ARM
|
||||
- [ ] Get arm-version booting on real hardware
|
||||
|
||||
## Drivers
|
||||
- [ ] Slim down driver specific program code
|
||||
- [ ] Remove entry/exit functions for drivers
|
||||
|
||||
## Filesystem
|
||||
- [ ] Create a vfs that ties into the capability system
|
||||
- [ ] Remote home directory
|
||||
- [ ] local file caching
|
||||
- [ ] remote file changes
|
||||
- [ ] Update file if the remote file changes
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
# Tooling
|
||||
## Repbuild
|
||||
- [ ] make generation of the ext2 image possible
