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

• xen/arm/page.h
• asm/mmu.h

Detected Declarations

• function xen_kernel_unmapped_at_usr

Annotated Snippet

#include <xen/arm/page.h>
#include <asm/mmu.h>

static inline bool xen_kernel_unmapped_at_usr(void)
{
	return arm64_kernel_unmapped_at_el0();
}

Annotation

• Immediate include surface: `xen/arm/page.h`, `asm/mmu.h`.
• Detected declarations: `function xen_kernel_unmapped_at_usr`.
• Atlas domain: Architecture Layer / arch/arm64.
• 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.
