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

• struct macio_dev
• function check_media_bay
• function lock_media_bay

Annotated Snippet

static inline void lock_media_bay(struct macio_dev *bay) { }
static inline void unlock_media_bay(struct macio_dev *bay) { }

#endif

#endif /* __KERNEL__ */
#endif /* _PPC_MEDIABAY_H */

Annotation

• Detected declarations: `struct macio_dev`, `function check_media_bay`, `function lock_media_bay`.
• Atlas domain: Architecture Layer / arch/powerpc.
• 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.
