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.

Annotation

• Immediate include surface: `linux/ctype.h`, `linux/kernel.h`, `linux/types.h`, `linux/string.h`.
• Detected declarations: `function Copyright`, `function strnlen`, `function strcmp`, `function strncmp`, `function simple_guess_base`, `function simple_strtoull`, `function simple_strtol`.
• 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.
