Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct device
• struct isp_platform_data

Annotated Snippet

struct isp_platform_data {
	void *adev;
	u32 asic_type;
	resource_size_t base_rmmio_size;
};

int isp_user_buffer_alloc(struct device *dev, void *dmabuf,
			  void **buf_obj, u64 *buf_addr);

void isp_user_buffer_free(void *buf_obj);

int isp_kernel_buffer_alloc(struct device *dev, u64 size,
			    void **buf_obj, u64 *gpu_addr, void **cpu_addr);

void isp_kernel_buffer_free(void **buf_obj, u64 *gpu_addr, void **cpu_addr);

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct device`, `struct isp_platform_data`.
• Atlas domain: Repository Root And Misc / include.
• 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.
