NibrasOS

Operating System Micro Kernel designed for IA-32 Arch.

If you're not familiar with Kernel Development, please close this page and stop wasting your time!

Requirements (Host-Machine):

• i386 Arch. (or x86_64)
• RAM >= 4GiB
• GNU-GCC-i386 cross-compiler
• PS/2 (optional)
• VHD (if running under VM)

feel free to contribute (please refer to 'TO BEs’)

TO BE FIXED:

• Process VAS creation
• TSS data gets lost when executing fork() or sys_fork()
• Reclaiming of usermode pocesses' VM pages

TO BE ADDED:

• More drivers (Networking, USB, SSD using DMAC)
• Device Manager
• FileSystems (primary: HFS, exFAT)
• Shells (at least bash, sh, csh)
• Power Managment
• IPC (basically: MP and Signalling)
• More C-stdlib functionalities
• Floating-point (SSE*)
• VM mmap
• VM86
• Long Mode support

TO BE STABLIZED:

• Process VAS security
• fork() syscall
• Kheap Manager
• Overall Structure (Higher-Half Kernel VM)
• Scheduling Algorithm: very basic RR is currently in use, the official algorithm used in NibrasOS is not within the source code, it is a new Scheduling Alg. that would be released once its scientific paper gets published

TO BE OPTIMIZED:

• Multiprocessing synchronization
• memcpy (using XMMs)
