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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• asm/tsc.h

Detected Declarations

• struct clocksource
• struct clock_event_device
• function arch_inlined_clocksource_read
• function arch_inlined_clockevent_set_next_coupled

Annotation

• Immediate include surface: `asm/tsc.h`.
• Detected declarations: `struct clocksource`, `struct clock_event_device`, `function arch_inlined_clocksource_read`, `function arch_inlined_clockevent_set_next_coupled`.
• Atlas domain: Architecture Layer / arch/x86.
• Implementation status: source 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.
