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

• core.h

Detected Declarations

• function dwc2_debugfs_init
• function dwc2_debugfs_exit

Annotated Snippet

#include "core.h"

#ifdef CONFIG_DEBUG_FS
int dwc2_debugfs_init(struct dwc2_hsotg *hsotg);
void dwc2_debugfs_exit(struct dwc2_hsotg *hsotg);
#else
static inline int dwc2_debugfs_init(struct dwc2_hsotg *hsotg)
{  return 0;  }
static inline void dwc2_debugfs_exit(struct dwc2_hsotg *hsotg)
{  }
#endif

Annotation

• Immediate include surface: `core.h`.
• Detected declarations: `function dwc2_debugfs_init`, `function dwc2_debugfs_exit`.
• 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.
