Robert Allan JamesandClaude Sonnet 5 dd043bbfeb Artemis Milestone 2e: PORTSC connect/disconnect detection, verified live
xhci_poll_events()'s Port Status Change branch now decodes the Port ID
from the event TRB (XHCI_PSC_EVT_PORT_ID, new in xhci.h), reads that
port's PORTSC.CCS via a new xhci_port_regs() helper, and logs connect vs.
disconnect. Acknowledges by writing back only PP (preserved) and CSC (the
bit being cleared) -- PED/PR/other _C bits written 0 so nothing is
accidentally disabled, reset, or silently cleared, matching the RW1C
discipline already used for ERDP.EHB in 2d.

Verified with the real target scenario via QMP hotplug on all three
architectures: boot with the xHCI controller present but no USB device
attached (confirmed zero port activity at ok>), then live
attach/detach/re-attach of a virtual USB thumb drive
(disk/usb-thumbdrive-test.img via usb-storage on xhci0.0). Full
connect->disconnect->connect cycle confirmed clean (no port wedge) on
amd64; single connect confirmed on aarch64 and riscv64.

Still open: correlating Command Completion Events back to their issuing
command, driving Enable Slot/Address Device from this connect path
(currently only a boot-time smoke test), and the callback surface into
Section U's higher-level code.

LithosAnanke v1.5.4

UEFI-bootable FORTH microkernel. Boots from firmware, initialises memory and interrupts, then runs the StarForth VM as its sole userspace runtime. No libc. No OS. Just stone and necessity.

Lithos (foundation) + Ananke (necessity) — the kernel under StarshipOS.


Status — M7.1 (Capsule System · Multi-VM Fleet)

Milestone Status
M0M6 UEFI boot · PMM · VMM · IDT · APIC · heap · framebuffer VT100 console (v1.5.1-FINAL) Complete
M7 StarForth VM integration + parity validation Complete
M7.1 Capsule birth protocol · Mama FORTH vocabulary · Tripod multi-VM fleet (Hermes/Artemis) · Word-level ACL (Phases 17) 🔄 In Progress
M8 REPL — keyboard input, interactive Forth Planned
M9 Block storage — AHCI driver Planned

POST at boot: parity hash verified across amd64/aarch64/riscv64 · Mama capsule dictionary: 453 words

What's live in M7.1

  • Tripod — a named multi-VM fleet (Hera the Mama VM, Artemis, two Hermes instances) births, runs, and re-births independently, verified booting live pre-REPL on all three architectures.
  • Hermes — a 17-block inter-VM messaging/channel layer between fleet members, with async delivery and channel negotiation.
  • Artemis — a Block Allocation Map (BAM) storage subsystem with Q48.16 block-heat tracking and cooldown/reclamation (ART-COOL/ART-REAP).
  • 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>). Phases 17 complete (C infrastructure, FORTH policy layer, zuse bootstrap superuser, Isabelle proof stubs, kernel parity); Phase 8 (Ed25519 PKI / thumbdrive challenge-response) is the only item remaining. Measured overhead once active on every check: +0.0054%+0.0088%, CV = 0.000%, across a 3×3 Latin-square DoE campaign (architecture × seed × 30 replicates) — three orders of magnitude below the measurement floor.
  • VM Fleet Attractor physics — the L8 Jacquard mode selector now has a real per-VM heat channel into fleet-wide tuning, replacing hardcoded compudynamics constants with a dynamically-inferred rate.
  • Kconfig build configuration — every physics/heartbeat/pipelining/ kernel-only tuning knob (~40 total) is now a discoverable, optional Kconfig symbol shared with the hosted VM build. See Quick Start below.

Quick Start

# Build kernel (requires cross-compilation toolchain, or native gcc)
make -f Makefile.starkernel ARCH=amd64

# Run in QEMU with OVMF
make -f Makefile.starkernel qemu

# Other architectures
make -f Makefile.starkernel ARCH=aarch64 qemu
make -f Makefile.starkernel ARCH=riscv64 qemu

Artifacts: build/amd64/kernel/starkernel_loader.efi · build/amd64/kernel/starkernel_kernel.elf

For the hosted VM by itself (Linux, no cross-compiler needed, no bare-metal tooling): see the separate StarForth repository — LithosAnanke used to be a branch inside that repo, now it's its own project with its own master.

Build configuration (optional)

Every kernel-only knob (STARFORTH_ENABLE_VM, PARITY_MODE, the shared physics/heartbeat family, etc.) is an optional Kconfig symbol — a plain make -f Makefile.starkernel uses the same defaults it always has unless you opt in:

make -f Makefile.starkernel ARCH=amd64 menuconfig
make -f Makefile.starkernel ARCH=amd64 kernel_amd64_defconfig
