}

Minimal CPU context saved/restored during N3 migration.

Layout is #[repr(C, align(64))] to match the ASM primitive offsets. No FPU/AVX state : handled separately per FPU policy. Total size: 96 bytes (fields) + 32 bytes (padding) = 128 bytes.

Fields

r15: u64

Callee-saved GPRs (System V AMD64 ABI).

r14: u64

r13: u64

r12: u64

rbp: u64

rbx: u64

rdx: u64

rax: u64

rflags: u64

Processor flags.

rsp: u64

Stack pointer.

rip: u64

Instruction pointer (handler entry or return address).

cr3_pcid: u64

CR3 value with PCID bits for N3b, or 0 for N3c.

_pad: [u8; 32]

Explicit padding to reach 128 bytes (align(64) requires this). Prevents implicit compiler padding and ensures deterministic layout for the ASM primitive.

Implementations
