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.

Dependency Surface

• asm/posix_types_64.h

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

/*
 * This file is only used by user-level software, so you need to
 * be a little careful about namespace pollution etc.  Also, we cannot
 * assume GCC is being used.
 *
 * These types should generally match the ones used by the 64-bit kernel,

Annotation

• Immediate include surface: `asm/posix_types_64.h`.
• 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.
