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.
As we are beginners in OSdev and low level programming, we have had to use and
read extensive amount of sources to have some understanging on the subject matter.
The names wouldn't fit here, but we shall reference OSdev Projects which contains a lot
of very good projects that can be used as references for learning.
We definitely have a great appreciation for every single one of them that helped us in any ways.
