The header scan (Captain Bob, 2026-11-10): 788 source files -- 351 with the
SL-1.0 header, 12 with the old name (docs/working/experiments, kept by
ruling), 31 under someone else's licence (tools/kconfig, Linux's, GPL-2.0:
kept), and 394 with none. Ruled: the SPDX form; capsules (.4th, .f18) and
proofs (.thy) left for a ruling of their own (mkcapsule's 64x16 block format,
content-addressed capsules).
253 files now begin

as a /* */ block (C, headers, assembly, linker scripts) or # lines (scripts,
Makefiles, Kconfig; below a shebang or a coding line); tools/mkcapsule.c,
which had the copyright line, gets the SPDX line only.
Not touched: docs/working/ (archive and old campaign material, as the
ruling kept the experiments); v4/system/post_cases.c (generated by
v4/tools/mkpost.py, "do not edit" -- the generator has the header).
Comments only: the kernel builds on amd64, aarch64, riscv64; make -C v4
test-32: 39 programs, 0 failures; every changed script parses.

* 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.
