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

• asm/cpu-features.h
• asm/mipsregs.h
• asm/ptrace.h
• asm/inst.h

Detected Declarations

• function mm_isBranchInstr
• function delay_slot
• function clear_delay_slot
• function set_delay_slot
• function exception_epc
• function compute_return_epc
• function MIPS16e_compute_return_epc

Annotated Snippet

if (inst->ri.opcode == MIPS16e_extend_op) {
			regs->cp0_epc += 4;
			return 0;
		}
		regs->cp0_epc += 2;
		return 0;
	}

	return __MIPS16e_compute_return_epc(regs);

Annotation

• Immediate include surface: `asm/cpu-features.h`, `asm/mipsregs.h`, `asm/ptrace.h`, `asm/inst.h`.
• Detected declarations: `function mm_isBranchInstr`, `function delay_slot`, `function clear_delay_slot`, `function set_delay_slot`, `function exception_epc`, `function compute_return_epc`, `function MIPS16e_compute_return_epc`.
• Atlas domain: Architecture Layer / arch/mips.
• 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.
