x64OS

its uefi compatible

Another attempt to write os using c++, now using limine boot protocol, sorry to risc-v and arm users, this os targets only amd64 based cpus, idk if im gotta support these cpus in future

Latest bootable iso link: from github actions

TODO List:

• GDT
• IDT
• PMM
• VMM
• Interrupts, timers
• Serial port(only COM1)
• Scheduler
• VFS
  • tmpfs
  • ext2/3/4
  • fat32
  • tarfs(basicly initrd)
  • Getting list of files and other stuff
• Program loading
• PCI
• Drivers support
• Networking
  • Ethernet
  • UDP
  • TCP
  • ICMP
  • more protocols support
• USB

Building and running

You need xorriso(for creating iso image), gcc(or clang, with amd64 instruction set support), nasm and make(reason why Makefile exists)

To build, use:

make # single core building
make -j$(nproc) # or multi threaded building

As a result, you get:

• bin/kernel.elf: Kernel
• image.iso: Bootable iso image, BIOS/UEFI(x32 and x64) compatible

Used source code/tools

Limine as bootloader

PMM Code taken from Lure OS

IDT/GDT Code taken from Boron OS

Frigg from managram project
