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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/module.h
• linux/irq.h
• linux/platform_data/asoc-imx-ssi.h
• irq-common.h

Detected Declarations

• function Copyright
• export mxc_set_irq_fiq

Annotated Snippet

if (exirq->set_irq_fiq) {
			struct irq_data *d = irq_get_irq_data(irq);
			ret = exirq->set_irq_fiq(irqd_to_hwirq(d), type);
		}
	}

	return ret;
}
EXPORT_SYMBOL(mxc_set_irq_fiq);

Annotation

• Immediate include surface: `linux/module.h`, `linux/irq.h`, `linux/platform_data/asoc-imx-ssi.h`, `irq-common.h`.
• Detected declarations: `function Copyright`, `export mxc_set_irq_fiq`.
• Atlas domain: Architecture Layer / arch/arm.
• Implementation status: integration 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.
