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

• boot.h

Detected Declarations

• function __section
• function __section
• function __section
• function __section
• function gettime
• function getchar
• function kbd_pending
• function kbd_flush
• function getchar_timeout

Annotated Snippet

if (t0 != t1) {
			cnt--;
			t0 = t1;
		}
	}

	return 0;		/* Timeout! */
}

Annotation

• Immediate include surface: `boot.h`.
• Detected declarations: `function __section`, `function __section`, `function __section`, `function __section`, `function gettime`, `function getchar`, `function kbd_pending`, `function kbd_flush`, `function getchar_timeout`.
• Atlas domain: Architecture Layer / arch/x86.
• 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.
