Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/errno.h
• linux/kernel.h
• linux/pci.h
• linux/of.h
• linux/of_irq.h
• linux/i2c.h

Detected Declarations

• struct i2c_driver_device
• function find_i2c_driver
• function pasemi_register_i2c_devices
• function for_each_child_of_node
• module init pasemi_register_i2c_devices

• Immediate include surface: `linux/errno.h`, `linux/kernel.h`, `linux/pci.h`, `linux/of.h`, `linux/of_irq.h`, `linux/i2c.h`.
• Detected declarations: `struct i2c_driver_device`, `function find_i2c_driver`, `function pasemi_register_i2c_devices`, `function for_each_child_of_node`, `module init pasemi_register_i2c_devices`.
• Atlas domain: Architecture Layer / arch/powerpc.
• Implementation status: integration 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.
