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

• function on_thread_stack

Annotated Snippet

#ifndef _ASM_POWERPC_STACKTRACE_H
#define _ASM_POWERPC_STACKTRACE_H

void show_user_instructions(struct pt_regs *regs);

static __always_inline bool on_thread_stack(void)
{
	return !(((unsigned long)(current->stack) ^ current_stack_pointer)
			& ~(THREAD_SIZE - 1));
}

#endif /* _ASM_POWERPC_STACKTRACE_H */

Annotation

• Detected declarations: `function on_thread_stack`.
• Atlas domain: Architecture Layer / arch/powerpc.
• 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.
