Adds the xHCI Configure Endpoint command for the two bulk endpoints identified by the previous increment, and fixes control-transfer sequencing to match the spec: xHCI 1.2 section 4.3.5 requires Configure Endpoint before SET_CONFIGURATION is sent to the device, the reverse of the order this driver used through 2f (which happened to work against QEMU's lenient qemu-xhci emulation but wasn't spec-correct). New XHCI_TRB_TYPE_CONFIGURE_ENDPOINT_CMD, EP Context type constants for Bulk IN/OUT, and an XHCI_EP_ADDR_TO_DCI() macro (DCI = 2*EndpointNumber + Direction) in xhci.h. xhci_cmd_configure_endpoint() builds the Input Context (Slot + one EP Context per DCI up to the highest bulk endpoint in use) and submits the command via the existing next_action deferral mechanism, correlated on completion via a new XHCI_CONN_AWAIT_CONFIGURE_ENDPOINT connect_state, then chains into the existing SET_CONFIGURATION path. Two allocations had to grow beyond what Address Device sized them for: the Input Context (previously room for one EP Context only) and, less obviously, the Device Context that DCBAA[slot_id] itself points at -- the controller only touches DCIs named in a command's own Add/Drop flags, so growing that buffer required copying its existing Slot+EP0 content forward rather than zeroing it, to avoid handing the controller a blank EP0 out from under an endpoint this command isn't touching. Bulk Transfer Rings (bulk_in_ring/bulk_out_ring) are allocated and wired into the new EP Contexts but not yet exercised by an actual transfer -- CBW/CSW submission is next. Verified live via QMP hotplug, all three architectures, byte-identical: bulk endpoint identification -> configure endpoint command submitted -> configure endpoint succeeded -> the existing set configuration -> device configured chain, then a clean disconnect/disable-slot teardown afterward with the larger Device Context installed. FABRIC-2.md Section X Milestone 2g's endpoint identify+configure checklist item marked fully done.

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 | |
|---|---|---|
| M0–M6 | 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 1–7) | 🔄 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 superuserzuse)ok>). Phases 1–7 complete (C infrastructure, FORTH policy layer,zusebootstrap 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
