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

Detected Declarations

• struct mvs_prd
• enum hw_registers
• enum pci_cfg_registers
• enum sas_sata_vsp_regs
• enum chip_register_bits

Annotated Snippet

struct mvs_prd {
	__le64			addr;		/* 64-bit buffer address */
	__le32			reserved;
	__le32			len;		/* 16-bit length */
};

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct mvs_prd`, `enum hw_registers`, `enum pci_cfg_registers`, `enum sas_sata_vsp_regs`, `enum chip_register_bits`.
• Atlas domain: Driver Families / drivers/scsi.
• 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.
