A 64-bit higher half kernel OS
You need an GCC compiler, ld linker which are usually pre-installed on UNIX-like systems. Also qemu, nasm, xorriso and make must be available.
We also use clang-format in the make format script, so make sure to have it installed in a development workspace.
In order to run the debugger, be sure to have gdb.
to compile and build in debug mode run:
maketo compile and build in production mode run:
make prodif you want to run the os using qemu, execute:
make runif you want to use gdb:
make drunthen open another shell and move to the same directory and:
make gdb| Feature | State |
|---|---|
| Limine bootloader | works |
| kernel loading | works |
| GDT | works |
| IDT | works |
| PIC | works |
| PIT | works |
| Keyboard | works |
| printf | works |
| basic prompt | works |
| Memory Mapping | works |
| process | works |
| context switching | works |
| thread | works |
| file system | basic vfs implemented |
| USTar | works |
| userspace | needs more testing |
| games | snake and gameoflife work |
| programs | cat, ls work |
| Feature to be implemented |
|---|
| maybe implement ACPI to gain access to more advanced devices |
| user space |
| support for simple file systems like FAT |
| support for ELF |
| syscalls to execute binaries like ELFs |
| simple hardware support like usb |
The goal is to implement a fully functional OS which would have basic tools and perhaps support libc and some Unix-like programs and applications.
Special thanks to the contributers of Lyre-OS for being one of the main references of ideas and implementation.
