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/ktime.h
• linux/workqueue.h

Detected Declarations

• struct adf_accel_dev
• struct adf_timer

Annotated Snippet

struct adf_timer {
	struct adf_accel_dev *accel_dev;
	struct delayed_work work_ctx;
	ktime_t initial_ktime;
};

int adf_timer_start(struct adf_accel_dev *accel_dev);
void adf_timer_stop(struct adf_accel_dev *accel_dev);

Annotation

• Immediate include surface: `linux/ktime.h`, `linux/workqueue.h`.
• Detected declarations: `struct adf_accel_dev`, `struct adf_timer`.
• Atlas domain: Driver Families / drivers/crypto.
• 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.
