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/timer.h
• ../i915_sw_fence.h

Detected Declarations

• struct timed_fence

Annotated Snippet

struct timed_fence {
	struct i915_sw_fence fence;
	struct timer_list timer;
};

void timed_fence_init(struct timed_fence *tf, unsigned long expires);
void timed_fence_fini(struct timed_fence *tf);

struct i915_sw_fence *heap_fence_create(gfp_t gfp);
void heap_fence_put(struct i915_sw_fence *fence);

Annotation

• Immediate include surface: `linux/timer.h`, `../i915_sw_fence.h`.
• Detected declarations: `struct timed_fence`.
• 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.
