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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/dmaengine.h

Detected Declarations

• struct mxs_ssp
• enum mxs_ssp_id

Annotated Snippet

struct mxs_ssp {
	struct device			*dev;
	void __iomem			*base;
	struct clk			*clk;
	unsigned int			clk_rate;
	enum mxs_ssp_id			devid;

	struct dma_chan			*dmach;
	unsigned int			dma_dir;
	enum dma_transfer_direction	slave_dirn;
	u32				ssp_pio_words[SSP_PIO_NUM];
};

void mxs_ssp_set_clk_rate(struct mxs_ssp *ssp, unsigned int rate);

Annotation

• Immediate include surface: `linux/dmaengine.h`.
• Detected declarations: `struct mxs_ssp`, `enum mxs_ssp_id`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
