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.

• 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.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/capability.h
• linux/io.h
• b43.h
• sysfs.h
• main.h
• phy_common.h

Detected Declarations

• function Copyright
• function b43_attr_interfmode_show
• function b43_attr_interfmode_store
• function b43_sysfs_register

Annotation

• Immediate include surface: `linux/capability.h`, `linux/io.h`, `b43.h`, `sysfs.h`, `main.h`, `phy_common.h`.
• Detected declarations: `function Copyright`, `function b43_attr_interfmode_show`, `function b43_attr_interfmode_store`, `function b43_sysfs_register`, `function b43_sysfs_unregister`.
• Atlas domain: Driver Families / drivers/net.
• Implementation status: source implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
