Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/bitfield.h
• linux/bits.h

Detected Declarations

• struct sh_msiof_spi_info

Annotated Snippet

	int tx_fifo_override;
	int rx_fifo_override;
	u16 num_chipselect;
	int mode;
	unsigned int dma_tx_id;
	unsigned int dma_rx_id;
	u32 dtdl;
	u32 syncdl;
};

Annotation

• Immediate include surface: `linux/bitfield.h`, `linux/bits.h`.
• Detected declarations: `struct sh_msiof_spi_info`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: source implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
