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

• No C-style include directives detected by the generator.

Detected Declarations

• struct i915_user_extension

Annotated Snippet

#ifndef I915_USER_EXTENSIONS_H
#define I915_USER_EXTENSIONS_H

struct i915_user_extension;

typedef int (*i915_user_extension_fn)(struct i915_user_extension __user *ext,
				      void *data);

int i915_user_extensions(struct i915_user_extension __user *ext,
			 const i915_user_extension_fn *tbl,
			 unsigned int count,
			 void *data);

#endif /* I915_USER_EXTENSIONS_H */

Annotation

• Detected declarations: `struct i915_user_extension`.
• Atlas domain: Driver Families / drivers/gpu.
• 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.
