Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

Dependency Surface

• linux/efi.h

Detected Declarations

• function efi_setup_5level_paging
• function efi_5level_switch

Annotated Snippet

static inline efi_status_t efi_setup_5level_paging(void) { return EFI_SUCCESS; }
static inline void efi_5level_switch(void) {}
#endif

Annotation

• Immediate include surface: `linux/efi.h`.
• Detected declarations: `function efi_setup_5level_paging`, `function efi_5level_switch`.
• Atlas domain: Driver Families / drivers/firmware.
• 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.
