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

• No C-style include directives detected by the generator.

Detected Declarations

• enum pt_capabilities
• function cpu_emergency_stop_pt
• function intel_pt_validate_cap
• function is_intel_pt_event

Annotated Snippet

static inline void cpu_emergency_stop_pt(void) {}
static inline u32 intel_pt_validate_hw_cap(enum pt_capabilities cap) { return 0; }
static inline u32 intel_pt_validate_cap(u32 *caps, enum pt_capabilities capability) { return 0; }
static inline int is_intel_pt_event(struct perf_event *event) { return 0; }

#endif /* _ASM_X86_INTEL_PT_H */

Annotation

• Detected declarations: `enum pt_capabilities`, `function cpu_emergency_stop_pt`, `function intel_pt_validate_cap`, `function is_intel_pt_event`.
• 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.
