JankOS

Download a bootable usb here

The best operating system you've ever laid eyes on. It's so good that barely does anything at all.

JankOS serves the purpose of an experiment in learning. Personally I'm unsatisfied with accepting an idea; I want to garner an intuition for the inner workings of an idea.

Done & Dusted

  • GDT Initialization - now ready to take steps to move to user mode

  • IDT Initialization - interrupt callbacks aren't firing but the table is initialized

Todo/Roadmap

  • Fixing Interrupt handlers - IRQ's now need to be implemented

  • Memory allocator

  • Paging will likely come before the allocator: If segmentation isn't being done then paging will be part of the roadmap(most likely)

Bugs

  • serial::serial_write(const char*, const u64) doesn't always write all the required data nor does it properly deal with the FIFO queue associated with the COM1 port.

  • stlio::printf still isn't feature complete

  • tests::* could always use more tests to cover as much of the code base as possible.
