GPU-first research operating system

Starfish

North star / never-ending improvement

A next-gen operating system with a direct road to the GPU for gaming and AI compute.

A lightweight, inspectable research OS below Yeho applications, YUI interfaces, and permissioned Yodi control.

  • Boot from our own loader into our own kernel, filesystem, userland, and shell.
  • A direct road from apps to pixels, GPUs, and AI compute without the legacy maze.
  • Multicore scheduling, syscalls, pipes, framebuffer, journaling, and hot edit-build-boot.

Current truth

Starfish intentionally prioritizes lab hackability over security. It is an early research system, not a hardened general-purpose OS.

Every subsystem has a door.

01

Intent

Direct, predictable, inspectable

nothing hidden
02

Connected stack

The OS, language, interface, and intelligence fit together

OS → language → UI → AI
03

First instruction

UEFI loader to kernel handoff

firmware → RDI
04

ABI

One explicit machine handoff

stable boundary
05

Core

A compact kernel you can trace

small enough to follow
06

Hardware

The practical device ladder

device → service
07

User boundary

Tiny userland, real process seams

ring 3
08

I/O path

Blocks, cache, queues, VFS

disk → pathname
09

Native filesystem

FIT64: File Index Table, 64-bit

FIT64 v0
10

On-disk anatomy

A volume you can draw on one page

block 0 → data
11

Recovery

Journal-only replay

begin → write → commit
12

Host toolkit

The filesystem ships with its microscope

17 tools

Streaming

FITPACK for contiguous workloads

blob + index
14

Compositor protocol

Surfaces, buffers, windows, fences

surface → present
15

Pixels

A procedural graphics direction

CPU first · GPU ready
16

Targets

Shared core, target-specific doors

one core · many stubs
17

Workbench

Edit, build, boot, observe

one-shot build
18

Boundaries

Research roadmap with honest edges

research, not hype
