Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/platform_device.h`, `linux/device.h`, `linux/module.h`, `linux/genalloc.h`, `linux/vmalloc.h`, `linux/dma-mapping.h`, `linux/list_sort.h`, `linux/libnvdimm.h`.
• Detected declarations: `function ndtest_config_get`, `function ndtest_config_set`, `function ndtest_get_config_size`, `function ndtest_ctl`, `function list_for_each_entry`, `function ndtest_release_resource`, `function range_index_show`, `function ndtest_create_region`, `function ndtest_init_regions`, `function put_dimms`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
