Written by me and gegy1000. We have implemented the following:

• Physical memory manager (buddy allocator)
• Virtual memory manager
• Kernel heap (buddy allocator)
• Serial (for logging)
• PIC, interrupts (incl. IST)
• PIT
• PS/2 (busy being reworked), keyboard input
• Snake game (runs on boot in kernel mode)
• ACPI (through acpi crate, with which we are involved)

Currently in progress:

• Userspace
• PS/2 rewrite
• System calls
