[OS Codename] roadmap

The current status and the future of this OS. A build (.iso file) will be released every time a Milestone is completed. The various milestones might be updated over the course of time.

3rd Milestone

  • GUI
    • lots of sketches and ideas

2nd Milestone

  • More filesystem stuff

    • ISO9660

  • Hard drive setup:

    • FAT32 (boot partition)
    • EXTx (system partition)

  • Syscalls

  • ELF loading

  • OS-specific toolchain

  • UNIX/POSIX compatibility layer (if someone wants to port coreutils, bash, whatever)

  • Basic shell

    • Configuration System (registry)
    • Enviroment Variables
    • Input and Ouput syscalls

  • Video modes

    • Set better screen resolutions other than limine's default
    • Some kind of graphics API
    • Oh yeah, DOOM because we have to :3

1st Milestone

  • Bare bones (Limine and 64-bit kernel)

  • printf implementation (+ E9 port "debugging")

  • GDT

  • Interrupt handling (IDT, ISRs, IRQs)

  • PIC support

  • PIT Driver

    • Initialization
    • PIT-supported sleep

  • LAPIC/IOAPIC Initialization

    • IRQ redirection to I/O APIC
    • Interrupts work
