Soaplin is a Limine-powered and UNIX-like operating system kernel mainly built for amd64.
0652010b1c
+ elf: Prevent dynamically linked programs from running on Soaplin. + sched: Support creating a process from a program_t structure. + syscall: Fix a bug where using syscall number 1024 would crash the OS. + syscall: Added a write syscall. It can only be used for writing to the standard output (FD: 1) |

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!
