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 iommu_domain
• enum pamu_stash_target

Annotated Snippet

#ifndef __FSL_PAMU_STASH_H
#define __FSL_PAMU_STASH_H

struct iommu_domain;

/* cache stash targets */
enum pamu_stash_target {
	PAMU_ATTR_CACHE_L1 = 1,
	PAMU_ATTR_CACHE_L2,
	PAMU_ATTR_CACHE_L3,
};

int fsl_pamu_configure_l1_stash(struct iommu_domain *domain, u32 cpu);

#endif  /* __FSL_PAMU_STASH_H */

Annotation

• Detected declarations: `struct iommu_domain`, `enum pamu_stash_target`.
• 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.
