This is an open source operating system. It uses docker as it's build environment. I will redo this later but for now it's just build instructions.
Requirements to run: Docker and QEMU
First run
docker build buildenv -t mangos-buildenv
to get your docker build environment set up. Then open your docker like this:
Linux/MacOS:
docker run --rm -it -v $(pwd):/root/env mangos-buildenv
Windows(CMD):
docker run --rm -it -v "%cd%":/root/env mangos-buildenv
Windows(Powershell):
docker run --rm -it -v "${pwd}:/root/env" mangos-buildenv
To actually build it, in your docker instance run
make build-x86_64
For x86_64(other architectures may come in the future)
Then type exit to leave the build environment and run
qemu-system-x86_64 -cdrom dist/x86_64/kernel.iso
from the project root folder.
TASKS TO DO
('✔' means done, '.' means in progress)
[✔] - Very basic printf that outputs to serial
- if the current char is '%' skip it and check the one after it
- if its 'd' take an integer
- if its 's' take a string
- if its 'p' take a pointer
[✔] - Make the kernel load its own GDT
[✔] - Implement an IDT
[✔] - Exception handling (i.e. just make an exception handler that prints when errors occur)
[✔] - Basic Log, uses ANSI escape codes for coloring errors differently from info.
[✔] - Find the "MMAP" tag in the addr and print out the areas of memory it tells you
[ ] - Make a page allocator (Bitmap, Page list, whichever one you feel like)
[ ] - Implement paging using the allocator
[ ] - Load the new page table
