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.

Dependency Surface

• asm/reg_ops.h

Detected Declarations

• function mfcr_hint
• function mfcr_ccr2

Annotated Snippet

#ifndef __ABI_REG_OPS_H
#define __ABI_REG_OPS_H
#include <asm/reg_ops.h>

static inline unsigned int mfcr_hint(void)
{
	return mfcr("cr31");
}

static inline unsigned int mfcr_ccr2(void)
{
	return mfcr("cr23");
}
#endif /* __ABI_REG_OPS_H */

Annotation

• Immediate include surface: `asm/reg_ops.h`.
• Detected declarations: `function mfcr_hint`, `function mfcr_ccr2`.
• Atlas domain: Architecture Layer / arch/csky.
• 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.
