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.

Annotated Snippet

* With module_init()/module_hid_driver() and the driver built into the kernel:
 *
 * Driver 'nzxt_smart2' was unable to register with bus_type 'hid' because the
 * bus was not initialized.

Annotation

• Immediate include surface: `linux/hid.h`, `linux/hwmon.h`, `linux/math.h`, `linux/module.h`, `linux/mutex.h`, `linux/spinlock.h`, `linux/wait.h`, `asm/byteorder.h`.
• Detected declarations: `struct unknown_static_data`, `struct fan_config_report`, `struct fan_status_report`, `struct set_fan_speed_report`, `struct drvdata`, `function scale_pwm_value`, `function handle_fan_config_report`, `function handle_fan_status_report`, `function nzxt_smart2_hwmon_is_visible`, `function nzxt_smart2_hwmon_read`.
• Atlas domain: Driver Families / drivers/hwmon.
• 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.
