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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/usb/composite.h
• linux/usb/cdc.h

Detected Declarations

• struct f_phonet_opts

Annotated Snippet

struct f_phonet_opts {
	struct usb_function_instance func_inst;
	bool bound;
	struct net_device *net;
};

struct net_device *gphonet_setup_default(void);
void gphonet_set_gadget(struct net_device *net, struct usb_gadget *g);
int gphonet_register_netdev(struct net_device *net);
void gphonet_cleanup(struct net_device *dev);

Annotation

• Immediate include surface: `linux/usb/composite.h`, `linux/usb/cdc.h`.
• Detected declarations: `struct f_phonet_opts`.
• Atlas domain: Driver Families / drivers/usb.
• 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.
