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.

Dependency Surface

• linux/cc_platform.h
• linux/ioport.h
• linux/eisa.h
• linux/io.h
• xen/xen.h

Detected Declarations

• function eisa_bus_probe
• module init eisa_bus_probe

Annotated Snippet

subsys_initcall(eisa_bus_probe);

Annotation

• Immediate include surface: `linux/cc_platform.h`, `linux/ioport.h`, `linux/eisa.h`, `linux/io.h`, `xen/xen.h`.
• Detected declarations: `function eisa_bus_probe`, `module init eisa_bus_probe`.
• Atlas domain: Architecture Layer / arch/x86.
• 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.
