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 an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• Touches IRQ or DMA behavior; this matters for the representative real-device path.
• 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/acpi.h`, `linux/kernel.h`, `linux/module.h`, `linux/pci.h`, `linux/thermal.h`, `int340x_thermal_zone.h`, `processor_thermal_device.h`.
• Detected declarations: `struct proc_thermal_pci`, `struct proc_thermal_mmio_info`, `enum proc_thermal_mmio_type`, `enum proc_thermal_msi_ids`, `function proc_thermal_mmio_read`, `function proc_thermal_mmio_write`, `function proc_thermal_threshold_work_fn`, `function pkg_thermal_schedule_work`, `function proc_thermal_clear_soc_int_status`, `function proc_thermal_irq_thread_handler`.
• Atlas domain: Driver Families / drivers/thermal.
• Implementation status: pattern implementation candidate.
• IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.

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.
