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.

Annotated Snippet

const struct csid_hw_ops csid_ops_340 = {

	.configure_stream = csid_configure_streams,
	.hw_version = csid_hw_version,

Annotation

• Immediate include surface: `linux/completion.h`, `linux/bitfield.h`, `linux/interrupt.h`, `linux/io.h`, `linux/kernel.h`, `camss.h`, `camss-csid.h`, `camss-csid-gen2.h`.
• Detected declarations: `enum csid_iface`, `function __csid_configure_rx`, `function __csid_configure_stream`, `function csid_configure_streams`, `function csid_reset`, `function csid_isr`, `function csid_configure_testgen_pattern`, `function csid_subdev_init`.
• Atlas domain: Driver Families / drivers/media.
• 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.
