# LithosAnanke v4.0.0-alpha.3
|
||
|
||
**UEFI-bootable FORTH microkernel.** Boots from firmware, initialises memory and interrupts, then
|
||
runs StarForth as its sole userspace runtime. No libc. No OS. Just stone and necessity.
|
||
|
||
*Lithos* (foundation) + *Ananke* (necessity) — the kernel under StarshipOS.
|
||
|
||
**Try it in your browser:** [starshipos-f18.com](https://starshipos-f18.com/) — a StarshipOS
|
||
machine of your own, booted to `[zuse@Hera] ok>`, thrown away when you leave. **Releases:**
|
||
[v4.0.0-alpha.3](https://gitea.starshipos-f18.org/rajames/LithosAnanke/releases) (pre-release),
|
||
the kernel `4.0.0-alpha.3` with the StarForth engine `3.2.0`.
|
||
|
||
---
|
||
|
||
## Products
|
||
|
||
StarForth v4 moves the engine onto a 32-instruction core derived from Chuck Moore's F18
|
||
(`docs/v4.0.0/`). With it, this repository carries three products, not one:
|
||
|
||
| Product | What it is |
|
||
|---|---|
|
||
| **Hosted StarForth F18** | The v4 engine as a native Linux build, for amd64, arm64 and riscv64. |
|
||
| **FPGA StarForth F18** | A 32-bit build of the same engine loaded into the FPGA: the gateway to the rest, the foundation everything else is built up from. |
|
||
| **StarshipOS** | The bare-metal product: LithosAnanke running StarForth. |
|
||
|
||
FORTH-79 is recomposed on the F18 engine and stored as a capsule; the StarshipOS-specific
|
||
vocabulary gets the same treatment. v3 remains the reference system until v4 meets its
|
||
acceptance criteria (`docs/v4.0.0/JUSTIFICATION.md` §16). **Both run on bare metal now:** every
|
||
board image carries v4 and v3, boots v4 as built, and one word in its boot configuration
|
||
chooses (see below) — except the PC stick, which is v4 only. **v3 is being retired** (its own
|
||
milestone, #156): what v4 needs of it, the block layer, moves into v4 and the rest is removed.
|
||

|
||
|
||
## Status
|
||
|
||
| Milestone | | Status |
|
||
|---|---|---|
|
||
| M0–M6 | UEFI boot · PMM · VMM · IDT · APIC · heap · framebuffer VT100 console | ✅ Complete |
|
||
| M7 | StarForth VM integration + parity validation | ✅ Complete |
|
||
| M7.1 | Capsule birth · Mama FORTH vocabulary · the Tripod fleet · kernel-Hermes · word-level ACL | ✅ Live |
|
||
| M8 | Keyboard input to the REPL — PS/2, virtio and **USB** keyboards (a full keyboard: Caps/Num Lock, keypad) | ✅ In QEMU, all three ISAs |
|
||
| M9 | Block storage — on v4, Artemis and Zuse's identity on the StarshipOS stick (GPT partitions, over USB mass storage); v3's Artemis on virtio-blk | ✅ In QEMU · real disks: no driver yet (`boards/BRINGUP.md` A4) |
|
||
| The stick | One USB stick is the whole OS: plug it in, boot, `[zuse@Hera] ok>` — its first boot mints its own Zuse and grows Artemis to fill it (`docs/v4.0.0/STICK.md`, #92) | ✅ Tasks 1–3 of 5 in QEMU · the real Zuse on a second stick next |
|
||
| Bare metal | a generic PC (amd64; first on the bench: a Beelink SER5), Raspberry Pi 5 (aarch64), Milk-V Mars (riscv64); Zynq-7020 (ARMv7) not yet ported | Images build; first boots on the bench — `boards/BRINGUP.md` |
|
||
|
||
**v4 is the default build, and v3 is being retired**: every kernel boots v4 unless its boot
|
||
arguments say `system=v3`. POST at boot, on all three ISAs: v4 — **538 tests**,
|
||
`PARITY:V4_SYSTEM word_count=317 dict_hash=0xfec8c47cfc6f437f`; v3 — **1052 tests**,
|
||
`PARITY:M7.1a word_count=526 hash=0x82f4ae7cb2e2d424`.
|
||
|
||
**How a change gets in** (the Captain Bob method): `master` is reached only through a pull request
|
||
that passed **acceptance** — amd64, aarch64 and riscv64 booted in QEMU to `[zuse@Hera] ok>`, POST
|
||
538/538 and one `dict_hash` on all three; the PC stick booted loaded above 2 GiB, as a PC's firmware
|
||
loads it; and the 32-bit build's tests. Every acceptance boot starts from a fresh stick, so every
|
||
run is a first boot. The same stages run nightly and for every release (`scripts/nightly.sh`); the
|
||
serial logs are committed.
|
||
|
||
### What's live
|
||
|
||
- **The Tripod** — a named multi-VM fleet: **Hera** (the Mama VM, the governor), **Artemis**
|
||
(block storage: a Block Allocation Map with Q48.16 block heat, cooldown and reclamation) and
|
||
**Hestia**, birthed, run and re-birthed independently on all three architectures.
|
||
- **kernel-Hermes** — messaging moved into the kernel (the Hermes VM is gone,
|
||
`docs/fabric/FABRIC-3.5.md`): every VM takes its own messages on its own turn, under a
|
||
cooperative switcher that every VM takes part in.
|
||
- **The plug-and-play stick** (v4) — `make boot_image TARGET=PC` and `make write_stick
|
||
DEVICE=/dev/sdX`, plug it in, boot: the stick's first boot mints its own Zuse (no two sticks share
|
||
one) and grows its Artemis partition to fill the stick, up to 256 GiB, writing metadata only.
|
||
- **Identities on thumbdrives** — Zuse, the superuser, and every user is a minted USB
|
||
thumbdrive (Ed25519, Zuse-signed); plugging one in births that user's VMs, pulling it out
|
||
ends them. There is only the drive: no password, no PIN.
|
||
- **Signed capsules** — the capsules the kernel boots from are signed under the StarshipOS Root CA
|
||
(`ci/pki/starshipos-root-ca.pem`, published with every release) and checked at boot.
|
||
- **Word-level ACL** — every dictionary entry carries a TTL/allow/mode/pin access-control
|
||
record; strict, TTL and pinned modes; two console layers (emergency `ok>` and superuser
|
||
`zuse)ok>`). Measured overhead of the live ACL-TTL mechanism: **+0.0603%**, CV 0.000%,
|
||
architecture-independent (`docs/fabric/FABRIC-1.md` §T).
|
||
- **Logs that persist** — every VM's log records go to a ring on Artemis's disk (`LOG-FLUSH`,
|
||
`LOG-SHOW`).
|
||
- **The physics-driven runtime** — seven feedback loops and the L8 Jacquard mode selector, with
|
||
a per-VM heat channel into fleet-wide tuning (VM Fleet Attractor).
|
||
- **Kconfig build configuration** — about 40 physics, heartbeat, pipelining and kernel-only
|
||
knobs, shared with the hosted build.

|
||
## Quick Start
|
||
|
||
```bash
|
||
# One boot image per physical target (output: build/boards/<board>/)
|
||
make boot_image TARGET=PC # any x86-64 UEFI PC -- GPT/ESP, BOOTX64.EFI
|
||
make boot_image TARGET=RASPI # Raspberry Pi 5 -- FAT, config.txt + kernel_2712.img + DTB
|
||
make boot_image TARGET=MILKV # Milk-V Mars -- GPT/ESP, BOOTRISCV64.EFI (U-Boot bootefi)
|
||
make boards # list boards (the Zynq-7020 has no ARMv7 port yet)
|
||
|
||
# Each image carries v4 and v3. As built it boots v4; to boot v3, change the one word
|
||
# system=v4 -> system=v3
|
||
# in starforth.cfg on the PC's stick or the Mars's card, or cmdline.txt on the Pi 5's card.
|
||
|
||
# The same TARGET drives all, docs and clean (make help)
|
||
make # every board with a kernel port + hosted v3 + the book
|
||
make docs # build/docs/LithosAnanke.pdf (LaTeX master: docs/book/main.tex)
|
||
make clean TARGET=RASPI # that board's outputs and build/aarch64/kernel
|
||
|
||
# The PC stick, written to a real USB stick (checks the device, asks you to type its name back,
|
||
# verifies the write); then boot it from the PC's firmware boot menu
|
||
make write_stick DEVICE=/dev/sdX
|
||
|
||
# The kernel in QEMU (OVMF / AAVMF / EDK2), one architecture at a time -- boots v4 from a fresh
|
||
# data stick, so every boot is a stick's first boot
|
||
make -f kernel/Makefile ARCH=amd64 clean qemu
|
||
make -f kernel/Makefile ARCH=aarch64 clean qemu
|
||
make -f kernel/Makefile ARCH=riscv64 clean qemu
|
||
make -f kernel/Makefile ARCH=amd64 clean qemu-stick-high # the PC stick itself, loaded high
|
||
make -f kernel/Makefile ARCH=amd64 KERNEL_ARGS=system=v3 clean qemu # v3, while it remains
|
||
|
||
# The Pi 5's native boot path, rehearsed on QEMU's virt machine at EL2
|
||
make -f kernel/Makefile ARCH=aarch64 RPI5_NATIVE_BASE=0x40080000 rpi5-rehearsal
|
||
```
|
||
|
||
Artifacts: `build/<arch>/kernel/starkernel_loader.efi` · `build/<arch>/kernel/starkernel_kernel.elf`
|
||
|
||
Tree: `kernel/` (LithosAnanke: `Makefile`, `src/`, `include/starkernel/`, `linker/`),
|
||
`v3/` (StarForth v3 engine and hosted build), `v4/` (StarForth v4, see `docs/v4.0.0/`),
|
||
`boards/<board>/` (`board.mk` + boot files), `capsules/` (the FORTH capsules). Every makefile
|
||
runs from the repo root; the root `Makefile` forwards any other goal to `v3/Makefile`.
|
||
|
||
For the hosted v3 VM by itself, see the separate **StarForth** repository — LithosAnanke used to
|
||
be a branch inside it, and is now its own project.
|
||
|
||
### Build configuration (optional)
|
||
|
||
Every kernel-only knob is an optional Kconfig symbol; a plain `make -f kernel/Makefile` uses
|
||
the defaults unless you opt in:
|
||
|
||
```bash
|
||
make -f kernel/Makefile ARCH=amd64 menuconfig
|
||
make -f kernel/Makefile ARCH=amd64 kernel_amd64_defconfig
|
||
```
