termOS

"Just a hobby, won't be big and professional like Linux."
— Linus Torvalds (and now me)

termOS is a 64-bit, UNIX-hating, bespoke operating system written from scratch in C.

Current Kernel: Dewar (v0.6.x)

Philosophy

• Zero Bloat: We don't port libraries; we write them.
• Custom Everything: Why use ELF when you can invent HOT!? Why use GRUB when you can write your own bootloader?

Features (v0.6.*)

• Architecture: x86_64 / UEFI.
• Memory Management: PMM (Bitmap), VMM (PML4 + Higher Half Direct Map), Kernel Heap.
• Multitasking: Preemptive scheduler with Round Robin.
• Isolation: Ring 0 (Kernel) / Ring 3 (Userspace) protection.
• Binaries: Custom HOT! executable format (parsed via custom elf2hot toolchain).
• Filesystem: VFS abstraction with CPIO Initramfs support.
• Graphics: linear framebuffer driver.
• Shell: termosh

🔥 The HOT! Format

termOS uses its own executable format called HOT!. Because parsing ELF headers is too mainstream. HOT! is a flat, segment-based format designed specifically for the Dewar kernel loader. Made only because ELF is Not-invented-here

Roadmap

See ROADMAP.md for the detailed plan of world domination (or at least self-hosting).
