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.
• 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

• sound/emu10k1.h
• sound/emux_synth.h

Detected Declarations

• struct snd_emu10k1_synth_arg

Annotated Snippet

struct snd_emu10k1_synth_arg {
	struct snd_emu10k1 *hwptr;	/* chip */
	int index;		/* sequencer client index */
	int seq_ports;		/* number of sequencer ports to be created */
	int max_voices;		/* maximum number of voices for wavetable */
};

Annotation

• Immediate include surface: `sound/emu10k1.h`, `sound/emux_synth.h`.
• Detected declarations: `struct snd_emu10k1_synth_arg`.
• Atlas domain: Driver Families / include/sound.
• 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.
