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

• struct task_struct

Annotated Snippet

#ifndef __ALPHA_SWITCH_TO_H
#define __ALPHA_SWITCH_TO_H


struct task_struct;
extern struct task_struct *alpha_switch_to(unsigned long, struct task_struct *);

#define switch_to(P,N,L)						 \
  do {									 \
    (L) = alpha_switch_to(virt_to_phys(&task_thread_info(N)->pcb), (P)); \
    check_mmu_context();						 \
  } while (0)

#endif /* __ALPHA_SWITCH_TO_H */

Annotation

• Detected declarations: `struct task_struct`.
• Atlas domain: Architecture Layer / arch/alpha.
• 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.
