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 toshsd_host

Annotated Snippet

struct toshsd_host {
	struct pci_dev *pdev;
	struct mmc_host *mmc;

	spinlock_t lock;

	struct mmc_request *mrq;/* Current request */
	struct mmc_command *cmd;/* Current command */
	struct mmc_data *data;	/* Current data request */

	struct sg_mapping_iter sg_miter; /* for PIO */

	void __iomem *ioaddr; /* mapped address */
};

Annotation

• Detected declarations: `struct toshsd_host`.
• Atlas domain: Driver Families / drivers/mmc.
• 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.
