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/types.h
• intel_display_reg_defs.h

Detected Declarations

• struct intel_display
• enum pipe
• function intel_lvds_port_enabled
• function intel_lvds_init
• function intel_is_dual_link_lvds

Annotation

• Immediate include surface: `linux/types.h`, `intel_display_reg_defs.h`.
• Detected declarations: `struct intel_display`, `enum pipe`, `function intel_lvds_port_enabled`, `function intel_lvds_init`, `function intel_is_dual_link_lvds`.
• 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.
