Robert Allan JamesandClaude Opus 5.5 33f4090d6d Stage MC-0b2: block subsystem behind g_lock_block (FABRIC-3.10.8 §3.3)
- block_subsystem.c (vendored): every public function's body becomes a
  static *_locked function; bodies call each other only through the
  _locked forms, breaking the internal cycles (relocate, meta relocate,
  migration scan, firsttouch, the meta accessors). Thin public wrappers
  take g_lock_block under __STARKERNEL__; hosted build has no lock and
  still builds clean.
- Lock order: hermes, switch, registry, doe, log, block, console, heap,
  vmm, pmm (Stadium, MC-0d, above block).
- Documented, not coverable by this lock: blk_get_buffer() pointers are
  used after release -- block-buffer ownership across cores is open for
  MC-3.
- Probe (removed): block lock balances on all three ISAs (2,057-2,379
  acquisitions), 0 recursions, 0 held at switch; vblk_io timeouts
  (0/0/4 probe, 0/0/2 acceptance) within the pre-lock riscv64 baseline
  of 0-6.
- Standard sequence on amd64/aarch64/riscv64: hashes and G byte-identical
  to MC-0b, MINT/WIREBIND/USE ok, conservation true, 0 idle growth.
- FABRIC-3.10.8 §3.2 wording fix; lock order noted as checked by
  inspection only.

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 (see tools/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.
