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.

Dependency Surface

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

Detected Declarations

• enum xen_mc_flush_reason
• enum xen_mc_extend_args

Annotated Snippet

#define _ASM_XEN_TRACE_TYPES_H

enum xen_mc_flush_reason {
	XEN_MC_FL_NONE,		/* explicit flush */
	XEN_MC_FL_BATCH,	/* out of hypercall space */

Annotation

• Detected declarations: `enum xen_mc_flush_reason`, `enum xen_mc_extend_args`.
• 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.
