Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• function setup_machine_tags

Annotated Snippet

void convert_to_tag_list(struct tag *tags);

#ifdef CONFIG_ATAGS
const struct machine_desc *setup_machine_tags(void *__atags_vaddr,
	unsigned int machine_nr);
#else
static inline const struct machine_desc * __init __noreturn
setup_machine_tags(void *__atags_vaddr, unsigned int machine_nr)
{
	early_print("no ATAGS support: can't continue\n");
	while (true);
	unreachable();
}
#endif

Annotation

• Detected declarations: `function setup_machine_tags`.
• Atlas domain: Architecture Layer / arch/arm.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
