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.
• 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/fs.h`, `linux/module.h`, `linux/kernel.h`, `linux/printk.h`, `linux/string.h`, `linux/wmi.h`, `bioscfg.h`, `../../firmware_attributes_class.h`.
• Detected declarations: `function display_name_language_code_show`, `function hp_get_integer_from_buffer`, `function hp_get_string_from_buffer`, `function hp_get_common_data_from_buffer`, `function hp_enforce_single_line_input`, `function hp_set_reboot_and_signal_event`, `function hp_calculate_string_buffer`, `function hp_wmi_error_and_message`, `function pending_reboot_show`, `function create_attributes_level_sysfs_files`.
• Atlas domain: Driver Families / drivers/platform.
• 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.
