live via QMP, ring sizing decided include/starkernel/xhci.h: Capability/Operational/Runtime register layouts, Port Register Set, Interrupter Register Set, Doorbell Array, 16-byte TRB struct -- all from the xHCI 1.2 spec, no existing reference in this tree to build from (unlike virtio-blk). volatile fields, no packed attribute, matching virtio_blk.c's documented riscv64/QEMU-MMIO precedent. Compile-checked clean, sizeof(xhci_trb_t) verified == 16. QEMU qemu-xhci's PCI vendor:device ID (0x1B36:0x000D) confirmed live via QMP query-pci against a real running instance -- not assumed from memory, matches the Milestone 1 QMP infrastructure just built. Ring sizing decided: fixed 256-TRB (one page) Command Ring and Event Ring, single interrupter -- documented rationale in the header. Bonus finding: src/starkernel/pci/pci.c already has more reusable infrastructure than Milestone 2b assumed (pci_find_first is ID-based lookup already existing; pci_bar/pci_map_bar/pci_enable are already generic) -- 2b is smaller than originally scoped, noted in the punch list.

include/starkernel/
Headers for LithosAnanke, the bare-metal UEFI kernel (src/starkernel/).
Built only via Makefile.starkernel; gated by __STARKERNEL__ when shared
with hosted code.
uefi.h— UEFI protocol/type definitions consumed by the loader.elf64.h,elf_loader.h— ELF64 parsing and kernel-image loading.boot_info_offsets.h— struct-offset constants shared between the assembly bootstrap and the C boot path.arch.h,apic.h,timer.h— architecture init, APIC interrupt controller, timer (TSC/HPET/APIC, 100 Hz heartbeat).console.h,framebuffer.h,vt100.h— UART 16550 console, framebuffer driver, and VT100 terminal emulation over the framebuffer.pmm.h,vmm.h,kmalloc.h— physical memory manager (bitmap allocator), 4-level x86_64 paging, kernel heap allocator.pci.h,virtio_blk.h— PCI enumeration and the VirtIO block device driver (disk backend for the kernel block subsystem).capsule.h,capsule_birth.h,capsule_loader.h,capsule_run.h,capsule_vm_physics.h,capsule_generated.h— capsule system types, birth protocol, physics-runtime capsule bindings, and the build-time- generated capsule directory (seetools/mkcapsule.c).kernel_args.h,cmdline.h— boot-time kernel argument parsing (starforth.cfg/ command line).repl.h— kernel REPL.log.h,doe_log.h— kernel logging and DoE metrics logging.q48_16.h— kernel-build copy of Q48.16 fixed-point arithmetic.xxhash64.h— content-addressing hash used for capsule IDs.hal_memory.h— hardware-abstraction-layer memory interface.
Subdirectories:
hal/— top-level hardware-abstraction-layer interface.vm/— kernel VM subsystem headers (capsule arena, parity logging, bootstrap wiring).freestanding/— minimal libc-shim headers (assert.h,ctype.h,errno.h,inttypes.h,math.h,sched.h,signal.h,stdio.h,stdlib.h,string.h,time.h,sys/time.h,sys/types.h) for building shared VM code in the freestanding kernel environment, where no real libc is available.
