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

• linux/kvm_types.h

Detected Declarations

• struct kvm_vmid

Annotated Snippet

	/*
	 * Writes to vmid_version and vmid happen with vmid_lock held
	 * whereas reads happen without any lock held.
	 */
	unsigned long vmid_version;
	unsigned long vmid;
};

Annotation

• Immediate include surface: `linux/kvm_types.h`.
• Detected declarations: `struct kvm_vmid`.
• Atlas domain: Architecture Layer / arch/riscv.
• 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.
