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

• linux/compiler_attributes.h

Detected Declarations

• struct drm_minor
• struct pvr_device
• struct dentry
• struct pvr_debugfs_entry
• function pvr_debugfs_init

Annotated Snippet

struct pvr_debugfs_entry {
	const char *name;
	void (*init)(struct pvr_device *pvr_dev, struct dentry *dir);
};

void pvr_debugfs_init(struct drm_minor *minor);
#else /* defined(CONFIG_DEBUG_FS) */
#include <linux/compiler_attributes.h>

static __always_inline void pvr_debugfs_init(struct drm_minor *minor) {}
#endif /* defined(CONFIG_DEBUG_FS) */

#endif /* PVR_DEBUGFS_H */

Annotation

• Immediate include surface: `linux/compiler_attributes.h`.
• Detected declarations: `struct drm_minor`, `struct pvr_device`, `struct dentry`, `struct pvr_debugfs_entry`, `function pvr_debugfs_init`.
• 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.
