Source tree reorganization: - Move StarForth v3 engine to v3/ (src/, include/, Makefile) - Move kernel to kernel/ (src/, include/, linker/, Makefile) - Create v4/ skeleton for F18-ISA golden model (DECOMPOSITION.md, JUSTIFICATION.md) - Move FABRIC-0..4.md to docs/fabric/ - Move ONTOLOGY.md and ROADMAP.md to docs/ Board infrastructure: - Add boards/ser5/, boards/raspi/, boards/milkv/, boards/zynq7020/ - Each board has board.mk (ISA, CPU flags, boot recipe) and README.md - Root Makefile becomes thin dispatcher: boot_image, all, clean, docs take TARGET - make boot_image TARGET=SER5|RASPI|MILKV builds one GPT/MBR image per board - ZYNQ7020 target exists but stops with clear error (ARMv7 port not built yet) - scripts/mkdiskimage.sh builds disk images for all boards Docs pipeline: - docs/book/ with LaTeX master (main.tex) and Makefile - pandoc converts Markdown to LaTeX at build time - Two Lua filters: table-widths.lua (wide tables wrap), code-breaks.lua (inline code breaks) - make docs builds single PDF (754 pages, 0 missing characters) - make docs TARGET=<board> adds board appendix - build/docs/<book|board>/meta.tex stamps git commit into PDF Bug fixes: - 42 include paths that only worked by accident now use correct relative paths - clang-18 hardcode replaced with configurable CC variable (fixed aarch64 build) - Pi 5: kernel_2712.img linked at 0x80000, .bss zeroed, memory reserved - Doxyfile, .clang-tidy, README.md, Kconfig paths updated Verified: - Hosted v3 build passes 1012 tests, 0 failures - SER5 image boots in QEMU (OVMF), POST passes, K exact (65536 = Q48_ONE) - Milk-V image boots in QEMU (OpenSBI + U-Boot + bootefi), POST passes - make clean TARGET=<board> removes only that board and its ISA objects - make all builds all boards, hosted v3, and docs in one run Co-authored-by: Junie <junie@jetbrains.com>

* boot_info_offsets.h — fixed byte offsets of BootInfo fields
|
|
*
|
|
* Read by kernel_entry.S (assembly) AND verified by _Static_assert in
|
|
* uefi_loader.c. Both uses share this header; only #define directives
|
|
* are used so the file is valid for the C preprocessor AND the GAS
|
|
* preprocessor (which runs on .S files compiled via CC).
|
|
*
|
|
* If you change the BootInfo struct layout in uefi.h, update the
|
|
* constants below AND re-check the _Static_asserts (search BOOT_INFO_OFFSETS).
|
|
*
|
|
* BootInfo layout (64-bit, natural alignment):
|
|
* 0: memory_map ptr (8)
|
|
* 8: memory_map_size u64 (8)
|
|
* 16: memory_map_descriptor_size u64 (8)
|
|
* 24: runtime_services ptr (8)
|
|
* 32: acpi_table ptr (8)
|
|
* 40: dtb ptr (8)
|
|
* 48: framebuffer FramebufferInfo (32)
|
|
* .base ptr (8)
|
|
* .size u64 (8)
|
|
* .width u32 (4)
|
|
* .height u32 (4)
|
|
* .pixels_per_scanline u32 (4)
|
|
* .pixel_format u32 (4)
|
|
* 80: uefi_boot_services_exited u8 (1)
|
|
* 81: [7 bytes padding]
|
|
* 88: kernel_stack_base ptr (8) ← BOOT_INFO_KERNEL_STACK_BASE_OFFSET
|
|
* 96: kernel_stack_size u64 (8) ← BOOT_INFO_KERNEL_STACK_SIZE_OFFSET
|
|
* 104: args KernelArgs
|
|
*
|
|
* 2026-08-03, punch-list item 0.3: `dtb` inserted at 40, shifting everything
|
|
* below it by 8. The _Static_asserts in uefi_loader.c caught the stale
|
|
* constants immediately — that is what they are for; do not silence them by
|
|
* moving a field, fix the offsets.
