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 hantro_jpeg_ctx

Annotated Snippet

struct hantro_jpeg_ctx {
	int width;
	int height;
	int quality;
	unsigned char *buffer;
	unsigned char hw_luma_qtable[JPEG_QUANT_SIZE];
	unsigned char hw_chroma_qtable[JPEG_QUANT_SIZE];
};

void hantro_jpeg_header_assemble(struct hantro_jpeg_ctx *ctx);

Annotation

• Detected declarations: `struct hantro_jpeg_ctx`.
• Atlas domain: Driver Families / drivers/media.
• 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.
