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

• clk_mgr.h
• dm_pp_smu.h
• clk_mgr_internal.h

Detected Declarations

• struct rn_clk_registers

Annotated Snippet

struct rn_clk_registers {
	uint32_t CLK1_CLK0_CURRENT_CNT; /* DPREFCLK */
};

void rn_clk_mgr_construct(struct dc_context *ctx,
		struct clk_mgr_internal *clk_mgr,
		struct pp_smu_funcs *pp_smu,
		struct dccg *dccg);

Annotation

• Immediate include surface: `clk_mgr.h`, `dm_pp_smu.h`, `clk_mgr_internal.h`.
• Detected declarations: `struct rn_clk_registers`.
• Atlas domain: Driver Families / drivers/gpu.
• 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.
