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
• linux/types.h

Detected Declarations

• struct amba_device
• struct amba_pl010_data
• struct dma_chan
• struct amba_pl011_data

Annotated Snippet

struct amba_pl010_data {
	void (*set_mctrl)(struct amba_device *dev, void __iomem *base, unsigned int mctrl);
};

struct dma_chan;
struct amba_pl011_data {
	bool (*dma_filter)(struct dma_chan *chan, void *filter_param);
	void *dma_rx_param;
	void *dma_tx_param;
	bool dma_rx_poll_enable;
	unsigned int dma_rx_poll_rate;
	unsigned int dma_rx_poll_timeout;
	void (*init)(void);
	void (*exit)(void);

Annotation

• Immediate include surface: `linux/bitfield.h`, `linux/bits.h`, `linux/types.h`.
• Detected declarations: `struct amba_device`, `struct amba_pl010_data`, `struct dma_chan`, `struct amba_pl011_data`.
• 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.
