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
• drm/intel/step.h

Detected Declarations

• struct drm_i915_private
• struct intel_step_info

Annotated Snippet

	/*
	 * It is expected to have 4 number steps per letter. Deviation from
	 * the expectation breaks gmd_to_intel_step().
	 */
	u8 graphics_step;	/* Represents the compute tile on Xe_HPC */
	u8 media_step;
};

Annotation

• Immediate include surface: `linux/types.h`, `drm/intel/step.h`.
• Detected declarations: `struct drm_i915_private`, `struct intel_step_info`.
• 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.
