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 v3d_perf_counter_desc
• struct v3d_perfmon_info

Annotated Snippet

struct v3d_perf_counter_desc {
	/* Category of the counter */
	char category[32];

	/* Name of the counter */
	char name[64];

	/* Description of the counter */
	char description[256];
};

struct v3d_perfmon_info {
	/* Different revisions of V3D have different total number of
	 * performance counters.
	 */
	unsigned int max_counters;

	/* Array of counters valid for the platform. */
	const struct v3d_perf_counter_desc *counters;
};

Annotation

• Detected declarations: `struct v3d_perf_counter_desc`, `struct v3d_perfmon_info`.
• 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.
