Short-Term Development Targets as of 2011/10/31

Harddisk Support

Write support for EXT2
Port EXT2 drivers to IDE -read-/write (superblock read testing was successful)
Build a better VFS with support for disk mounting
-Get all of the example binaries onto a hard disk image-
PORT GCC

Operation Viper

Port ncurses
- Requires some terminal-related C library functions
Port Vim
- Requires directory support
- Disable command execution?

Development Targets as of 2011/10/21

I/O

/dev file system
/dev/fbN and /dev/ttyN for virtual framebuffer terminals and graphics
/dev/ttyS0 for serial I/O
Support framebuffer switching via keyboard
Remove hardcoded special-casing for stdin/stdout/stderr
SATA read/write drivers (/dev/sdaN)
/dev/ramdisk (read-only)
EXT2 write support (including file creation, directory creation, rm, unlink, etc.)
EXT2 drivers should operate on a /dev/* file
Mounting of /dev/* files using a filesystem handler
VFS tree

libc

Fork newlib
Changes for newlib should be moved to a git repository
Fix 64-bit host builds?
dirent.h support; readdir in kernel
Entire user-space library set should build from scratch on any compatible system
Consider working with glib?

GCC

Port GCC
Port yasm, make

Task Management

-Fix user-mode fork-
-Add user-mode wait- (with queues!)
Signals (signal(), kill(), etc.)

Signals and Exceptions

SIGDIAF (Die in a fire)

EOH

EOH, "Engineering Open House", is an annual event held at the University of Illinois at Urbana-Champaign which showcases student projects and research.

Primary Plans

Windowing environment
More user applications

Details

Windowing Environment

EOH is focused on making stuff that looks cool. Judges are impressed by things they can see, thus the primary target for EOH is a GUI.

Complete the windowing environment (which will eventually be rebuilt to implement Wayland, in the far future), will require:

Pipes (for user applications, terminal windows, etc.)
Shared memory buffers (single writer; client-server model; for window graphics buffers)
Input device files (for mouse and keyboard reads)

Additionally, it would be nice to have:

Freetype (for smooth, unicode text rendering; I have had difficulties getting Freetype to process font files, this may be a bug in the ELF loader; try to trace what calls Freetype normally makes to figure thise out)
There is an embedded, pure-software implementation of OpenGL; consider porting it (because 3d stuff is cool)

Applications

Both for the purpose of demonstrating the windowing environment and to make とあるOS more usable, it would be ideal to have a few usable applications.

A simple editor (I would love to port something real like Vim, but this has proven difficult due to external requirements)
Graphical applications such as:
- A calculator
- Some simple game (perhaps minesweeper)
- An analog clock
A compiler for something, even if it isn't C.
