Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• kvm_util.h

Detected Declarations

• struct guest_mode

Annotated Snippet

struct guest_mode {
	bool supported;
	bool enabled;
};

extern struct guest_mode guest_modes[NUM_VM_MODES];

#define guest_mode_append(mode, enabled) ({ \
	guest_modes[mode] = (struct guest_mode){ (enabled), (enabled) }; \
})

void guest_modes_append_default(void);
void for_each_guest_mode(void (*func)(enum vm_guest_mode, void *), void *arg);
void guest_modes_help(void);
void guest_modes_cmdline(const char *arg);

Annotation

• Immediate include surface: `kvm_util.h`.
• Detected declarations: `struct guest_mode`.
• Atlas domain: Support Tooling And Documentation / tools.
• 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.
