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

• uapi/asm/papr-sysparm.h

Detected Declarations

• struct papr_sysparm_buf

Annotated Snippet

	__be16 len;
	u8 val[PAPR_SYSPARM_MAX_OUTPUT];
};

void papr_sysparm_buf_free(struct papr_sysparm_buf *buf);
int papr_sysparm_set(papr_sysparm_t param, const struct papr_sysparm_buf *buf);
int papr_sysparm_get(papr_sysparm_t param, struct papr_sysparm_buf *buf);

Annotation

• Immediate include surface: `uapi/asm/papr-sysparm.h`.
• Detected declarations: `struct papr_sysparm_buf`.
• 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.
