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 device_node
• struct generic_pm_domain

Annotated Snippet

#ifndef __CPUIDLE_PSCI_H
#define __CPUIDLE_PSCI_H

struct device_node;
struct generic_pm_domain;

void psci_set_domain_state(struct generic_pm_domain *pd, unsigned int state_idx,
			   u32 state);
int psci_dt_parse_state_node(struct device_node *np, u32 *state);

#endif /* __CPUIDLE_PSCI_H */

Annotation

• Detected declarations: `struct device_node`, `struct generic_pm_domain`.
• Atlas domain: Driver Families / drivers/cpuidle.
• 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.
