OpenBios in Loader

OpenBIOS is a free, portable implementation of IEEE 1275-1994 (Open Firmware). Find detailed information about OpenBIOS OpenBIOS can replace your system firmware (BIOS) partly or completely. It can also be used as a bootloader to create an Open Firmware compatible interface between legacy firmware and an operating system. This is achieved by a modular concept that consists of a portable Forth kernel and three interfaces for user interaction, device initialization and client (operating system) control in command line like shell in Linux. OpenBios implentation Fcode [1] - Bytecode is small, hardware independent and efficient. And an evaluator (bytecode virtual machine) is almost trivial to implement or/and with possible an uses JIT technology.

• Primary goal: Add OpenBios ("Forth") support to the system bootloader.
• Additional goal: Create simple interactive more device drivers
• Language: Forth, FASM (Assembler), C
• Links: Openbios Firmware in Github

File system

• Primary goal: Add write support for ext4 file system (ext4 reading and ext2 writing are already supported).
• Additional goal: Improve write support for NTFS file system.
• Language: FASM (Assembler)
• Links: Ext4 Disk Layout

Widget toolkit

• Primary goal: Extend Box_lib (a set of separate widgets) to create a full-featured widget toolkit, design architecture and implement focus handling, callbacks and other core ideas.
• Additional goal: Integrate created box_lib widgets to the C-framework, extend framework with font handling, layout manager
• Language: FASM (Assembler), C (framework)
• Links: basic idea, list of toolkits

Port Mbed TLS

• Primary goal: Make a working port of Mbed TLS (previously PolarSSL) as native KolibriOS MS COFF library and add it to the automatic build-system. (done)
• Additional goal: Update HTTP library (written in FASM) to support HTTPS. (todo)
• Language: C/FASM
• Links: Forum thread about polarSSL, HTTP library on WebSVN, Port of mbedTLS to Kolibri (as a static library) + working example

Port FLTK

• Primary goal: Make a working port of FLTK (widget library) and add it to the automatic build-system.
• Additional goal: port Scintilla (minimum working version)
• Language: C++
• Links: Official site

Language: C--, Assembler/FASM

Fasmg port

Tomasz Grysztar (creator of FASM) introduced FASMG, a new assembler engine. It would be nice to support its new syntax in KolibriOS.

• Primary goal: Write FASMG application like FASM one. Port standard KolibriOS macros to FASMG syntax.
• Additional goal: Implement macros for compatibility with FASM.
• Language: Assembler/FASM/FASMG
• Links: FASMG overview, FASMG manual

Unicode library

Unicode is a huge and sophisticated standard. Nevertheless modern OS should provide libraries with Unicode related routines like NFC, NFD, sorting, comparing, etc.

• Primary goal: Write a tiny Unicode library with core Unicode algorithms and example application.
• Additional goal: Upgrade existing applications to use the new library.
• Language: Assembler/FASM
• Links: libutf

Virt-IO driver

Virtio is a virtualization standard for network and disk device drivers where just the guest's device driver "knows" it is running in a virtual environment, and cooperates with the hypervisor. This enables guests to get high performance network and disk operations, and gives most of the performance benefits of paravirtualization.

• Primary goal: Write kernel driver for, say, virt-io Ethernet card.
• Additional goal: Write more drivers.
• Language: Assembler/FASM
• Links: Virt-IO wiki

Loop device driver

• Primary goal: Write loop device driver and example application to manage loop devices.
• Additional goal: Prepare a set of disk images to be used in filesystem unit tests.
• Language: Assembler/FASM
• Links: loop device overview

RSS/Atom news reader

RSS and Atom are standards for web feeds. They are XML based and easily processed via AsmXml library. Corresponding user application would be a big plus to usability of KolibriOS.

• Primary goal: Write RSS news reader as a standalone KolibriOS application.
• Additional goal: Add Atom support to the app.
• Language: Assembler/FASM
• Links: AsmXml library, RSS, Atom

Port SDL2

SDL1.2 is already ported to KolibriOS, but there is no SDL2 port.

• Primary goal: Make a working port of SDL2.
• Additional goal: Port some program/game that uses SDL2 library.
• Language: C
• Links: libsdl.org

Add forms to WebView

Currently WebView browser doesn't support support html forms (<form>, <input>, etc.)

• Primary goal: Add support for <form>, <input> for types that was prior to HTML5
• Additional goal: Add input types that was introduced in HTML5
• Language: C--
• Links: WebView on svn

J2ME Emulator

Thousands of games and programs have been created for the j2me platform. It would be cool to be able to run them in KolibriOS.

• Primary goal: Port JVM and java.microedition.* runtime
• Additional goal: Make it run most of popular j2me games
• Language: C, Java
• Links: miniJVM

Most importantly... Have Fun!
