Soaplin

The Soaplin kernel is a new Unix-like operating system kernel.

Features

• x86_64 support (kinda)
• Memory management (VMM/PMM/VMA/kmalloc)
• Simple pre-emptive scheduler
• Ring 3 (user mode) support
• ELF loader
• ACPI
• Symetric Multiprocessing (It runs code, but the scheduler is running on 1 processor.)

In the works

• Virtual File System
• FPU support

To come

• RTC support
• EXT2 driver
• FAT32 driver
• TAR-based init ram disk
• Video driver for Bochs graphics adapter, and the VMware display adapter.

Known bugs

• If a user process calls the syscall handler by using interrupts, the system may crash due to a Page Fault.

Building

To build Soaplin, you must ensure you have these:

• The Netwide Assembler (nasm)
• A compiler (both GCC & Clang works!) (In the future, a custom toolchain would be built.)
• A linker (both GNU LD & LLVM linker works too!)

Clone the repo, and run "make" in it!
