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

• ufs/ufshcd.h

Detected Declarations

• struct ufshcd_dme_attr_val
• enum rx_fsm_state
• enum tx_fsm_state

Annotated Snippet

	u32 attr_sel;
	u32 mib_val;
	u8 peer;

Annotation

• Immediate include surface: `ufs/ufshcd.h`.
• Detected declarations: `struct ufshcd_dme_attr_val`, `enum rx_fsm_state`, `enum tx_fsm_state`.
• Atlas domain: Driver Families / drivers/ufs.
• 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.
