MY OS

(I did not decided how to name it)

This is small project about developing x86 kernel. Currently, I follow guides from https://wiki.osdev.org. I want to make it posix compliant as far as I can.

Features working:

• VGA terminal output
• Memory management using paging (on for kernel space, as I don't have any user space). It uses my allocator from https://github.com/romasku/lpalloc.
• Interrupts handling (only prints IRQ number on display)

Building and running

Build system is cmake. I suggest using qemu to run kernel (it is multiboot compliant kernel).

To Build:

cmake CMakeLists.txt -B cmake-build-debug
cd cmake-build-debug
make

To Run:

./tools/run-qemu.sh

Dependencies

To be able to build, you'll need a i686-elf-gcc cross-compiler. On arch, you can try to use i686-elf-gcc AUR package. If you use other distro/platform, please refer to osdev wiki, it has comprehensive guide how to build cross compiler. After installation, please make sure that i686-elf-gcc executable is in your PATH. CMake script assume that it's there.

To be able to run, please install qemu. On Arch linux, it can be done using sudo pacman -S qemu, on ubuntu, you can use sudo apt install qemu.

TODO

• Implement keyboard driver
