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 hdcp_protection_message
• enum hdcp_message_id
• enum hdcp_version
• enum hdcp_link
• enum hdcp_message_status

Annotated Snippet

	enum hdcp_message_id msg_id;
	uint32_t length;
	uint8_t max_retries;
	uint8_t *data;
	enum hdcp_message_status status;

Annotation

• Detected declarations: `struct hdcp_protection_message`, `enum hdcp_message_id`, `enum hdcp_version`, `enum hdcp_link`, `enum hdcp_message_status`.
• 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.
