用 Rust 编写内存安全的 NPU 内核程序：ascend-rs 项目实践

1. 背景：NPU 编程的现状与挑战

为什么关注内存安全？

在异构计算领域，GPU/NPU 编程长期以来依赖 C/C++ 生态。CUDA、OpenCL、SYCL 等框架虽然功能强大，但继承了 C/C++ 的所有内存安全问题：悬垂指针、缓冲区溢出、数据竞争、资源泄漏。这些问题在异构环境中尤为棘手——设备内存与宿主内存的交互增加了额外的复杂性。

一次典型的 NPU 编程失误可能表现为：

// C++ AscendC: 忘记释放设备内存 → 内存泄漏
void* devPtr;
aclrtMalloc(&devPtr, size, ACL_MEM_MALLOC_HUGE_FIRST);
// ... 使用 devPtr 做计算 ...
// 如果这里发生异常，aclrtFree 永远不会被调用
aclrtFree(devPtr);

Rust 的所有权系统和 RAII（资源获取即初始化）模式能够在编译期消除这类问题。这正是 ascend-rs 项目的核心动机。

开源生态现状

目前，异构计算的内存安全编程领域已有一些探索：

项目	目标硬件	方法	状态
rust-cuda	NVIDIA GPU	Rust → PTX 编译，CUDA 安全绑定	不再活跃
rust-gpu	GPU (Vulkan)	Rust → SPIR-V 编译	活跃
krnl	GPU (Vulkan)	安全的 GPU 计算内核	活跃
cudarc	NVIDIA GPU	CUDA 运行时安全绑定	活跃
ascend-rs	华为昇腾 NPU	Rust → MLIR → NPU 编译，ACL 安全绑定	开发中

可以看到，昇腾 NPU 生态中，ascend-rs 是目前唯一一个尝试同时在宿主机端和设备端实现 Rust 内存安全编程的项目。 这填补了 Ascend 生态的一个重要空白。

ascend-rs 项目架构

ascend-rs 采用三层架构：

graph TD
    A["应用层<br/>用户的 Rust 程序"] --> B["宿主机 API 层<br/>ascend_rs + ascend_sys<br/>RAII 安全封装"]
    A --> C["设备运行时层<br/>ascend_std + rustc_codegen_mlir<br/>#![no_core] 运行时 | MLIR 代码生成后端"]
    B --> D["CANN SDK · C/C++ 底层库<br/>ACL Runtime · AscendCL · bisheng · bishengir · HIVM"]
    C --> D

宿主机 API 层通过 bindgen 自动生成 FFI 绑定，并在其上构建安全的 Rust 封装：Acl、Device、AclContext、AclStream、DeviceBuffer<T> 等，利用生命周期系统确保资源使用的正确顺序。

设备运行时层更具创新性：它包含一个自定义的 rustc 代码生成后端，将 Rust 代码编译为 MLIR。之后，mlir_to_cpp 翻译步骤将 MLIR 转换为带有 AscendC API 调用的 C++ 源码，再由 bisheng（CANN C++ 编译器）编译为 NPU 可执行二进制——昇腾 910B 和 310P 均采用这条路径。这条 MLIR-to-C++ 路径提供了完整的 AscendC 特性支持——DMA 操作、向量指令、流水线屏障和 TPipe 基础设施。翻译器识别 MLIR 中的 ascend_* 函数调用，并生成相应的 AscendC 向量操作。

2. Hello World：第一个 NPU 程序

让我们从最简单的例子开始。这个 Hello World 示例展示了 ascend-rs 宿主机 API 的基本用法——用 Rust 安全地初始化 NPU、创建执行上下文、启动内核。

内核代码（C++）

在当前阶段，Hello World 使用 C++ 内核，这是 CANN SDK 的原生方式：

// hello_world.cpp
#include "kernel_operator.h"

extern "C" __global__ __aicore__ void hello_world() {
    AscendC::printf("Hello World!!!\n");
}

extern "C" void hello_world_do(uint32_t blockDim, void *stream) {
    hello_world<<<blockDim, nullptr, stream>>>();
}

这里的 __global__ 标记函数为可从宿主机调用的入口点，__aicore__ 表明它运行在昇腾的 AI Core 上。<<<...>>> 语法与 CUDA 类似，指定了并行度和执行流。

宿主机代码（Rust）

宿主机代码展示了 ascend-rs 最重要的设计理念——RAII 资源管理和生命周期安全：

use ascend_rs::prelude::*;
use std::error::Error;

// 声明 C++ 内核的 FFI 接口
unsafe extern "C" {
    fn hello_world_do(dim: u32, stream: *mut std::ffi::c_void);
}

fn main() -> Result<(), Box<dyn Error>> {
    // 步骤 1: 初始化 ACL 运行时
    let acl = Acl::new()?;

    // 步骤 2: 选择并初始化设备
    let device = Device::new(&acl)?;

    // 步骤 3: 创建执行上下文和流
    let context = AclContext::new(&device)?;
    let stream = AclStream::new(&context)?;

    // 步骤 4: 启动内核（8 个并行块）
    unsafe {
        hello_world_do(8, stream.to_raw());
    }

    // 步骤 5: 同步等待内核完成
    stream.synchronize()?;

    // 步骤 6: 所有资源自动释放（RAII）
    // Drop 顺序: stream → context → device → acl
    Ok(())
}

关键设计：生命周期链

注意这段代码的类型签名：

Acl                    → 生命周期根
  Device<'acl>         → 必须在 Acl 之前析构
    AclContext<'d>     → 必须在 Device 之前析构
      AclStream<'c>   → 必须在 Context 之前析构

如果你试图以错误的顺序使用这些资源，代码将无法通过编译。 这是 Rust 类型系统的力量——在编译期保证了资源管理的正确性，而 C++ 只能依赖程序员的纪律。

对比：C++ 版本的隐患

等价的 C++ 代码需要手动管理每个资源的生命周期：

// C++ 版本：每个资源都需要手动释放
aclInit(nullptr);
aclrtSetDevice(0);
aclrtContext ctx;
aclrtCreateContext(&ctx, 0);
aclrtStream stream;
aclrtCreateStream(&stream);

hello_world_do(8, stream);
aclrtSynchronizeStream(stream);

// 必须按正确顺序手动释放，否则导致未定义行为
aclrtDestroyStream(stream);
aclrtDestroyContext(ctx);
aclrtResetDevice(0);
aclFinalize();

如果任何一步抛出异常或提前返回，后续的清理代码将被跳过。而 Rust 版本中，Drop trait 保证了无论控制流如何变化，资源都会被正确释放。

3. 深入实践：用 Rust 编写 NPU 内核

Hello World 展示了宿主机端的安全性。但 ascend-rs 更大的愿景是：在设备端也使用 Rust。这意味着用 Rust 编写运行在 NPU 上的内核代码，而不是 C++。

让我们通过一个完整的向量乘法（vec_mul）示例来展示这一过程。

3.1 Rust 内核代码

这是运行在 NPU 上的 Rust 代码：

// kernels/src/lib.rs

// 关键：#![no_core] 表示这是一个完全裸机环境
#![feature(no_core)]
#![no_std]
#![no_core]

/// 逐元素向量乘法: z[i] = x[i] * y[i]
///
/// #[ascend_std::aiv_kernel] 将此函数标记为 NPU 内核入口点
#[ascend_std::aiv_kernel]
pub unsafe fn mul(x: *const u16, y: *const u16, z: *mut u16) {
    unsafe {
        // 总元素数 = 16，在各并行块之间均匀分配工作
        let block_size = 16usize / ascend_std::get_block_num();
        let start = ascend_std::get_block_idx() * block_size;
        let mut i = start;
        loop {
            // 逐元素相乘并写入输出
            *z.wrapping_add(i) = *x.wrapping_add(i) * *y.wrapping_add(i);

            i = i + 1;
            if i == block_size + start {
                break;
            }
        }
    }
}

这段代码有几个值得注意的地方：

#![no_core] 环境：NPU 没有操作系统，也没有标准库。ascend_std 提供了 Rust 核心类型（Copy、Clone、Add、Mul 等）的最小化重实现，使得 Rust 代码能够在裸机环境下编译。

#[ascend_std::aiv_kernel]：这个属性宏标记函数为 AIV（Ascend Instruction Vector）内核入口点。它展开为 #[unsafe(no_mangle)]（使得宿主机可以按名称查找符号）和 #[ascend::aiv_kernel]（让 MLIR 代码生成后端识别并添加 hacc.entry 属性）。

NPU 并行模型：与 CUDA 的 block/thread 模型类似，昇腾 NPU 使用 block 和 sub-block 来组织并行计算。get_block_idx() 和 get_block_num() 提供了执行上下文信息，使内核能够确定自己负责处理的数据范围。

3.2 宿主机代码

宿主机代码负责数据搬运、内核加载和结果验证：

// src/main.rs
use ascend_rs::prelude::*;

fn main() -> anyhow::Result<()> {
    // ── 第一阶段：初始化 ──
    let acl = Acl::new()?;
    let device = Device::new(&acl)?;
    let context = AclContext::new(&device)?;
    let stream = AclStream::new(&context)?;

    // ── 第二阶段：数据准备 ──
    let x_host = common::read_buf_from_file::<u16>("test_data/input_x.bin");
    let y_host = common::read_buf_from_file::<u16>("test_data/input_y.bin");

    // 使用 HugeFirst 策略分配设备内存（优先使用大页，提升 TLB 效率）
    let mut x_device = DeviceBuffer::from_slice_with_policy(
        x_host.as_slice(), AclrtMemMallocPolicy::HugeFirst
    )?;
    let mut y_device = DeviceBuffer::from_slice_with_policy(
        y_host.as_slice(), AclrtMemMallocPolicy::HugeFirst
    )?;
    let mut z_device = unsafe {
        DeviceBuffer::<u16>::uninitialized_with_policy(
            x_host.len(), AclrtMemMallocPolicy::HugeFirst
        )?
    };

    // ── 第三阶段：内核执行 ──
    unsafe {
        // KernelLoader 从 build.rs 编译产物中加载 NPU 二进制
        let kernel_loader = KernelLoader::new()?;

        // 通过符号名 "mul" 获取内核句柄
        let kernel = kernel_loader.get_kernel("mul")?;

        // 以 2 个并行块启动内核
        let block_dim: u32 = 2;
        let mut args = [
            x_device.as_mut_ptr() as *mut _,
            y_device.as_mut_ptr() as *mut _,
            z_device.as_mut_ptr() as *mut _,
        ];
        kernel.launch(block_dim, &stream, &mut args)?;
    }

    // ── 第四阶段：同步与验证 ──
    stream.synchronize()?;
    let res = z_device.to_host()?;

    for (idx, elem) in res.iter().enumerate() {
        let expected = x_host[idx].wrapping_mul(y_host[idx]);
        assert_eq!(*elem, expected);
    }

    Ok(())
}

3.3 构建系统

build.rs 是连接 Rust 工具链和 CANN 编译器的桥梁：

// build.rs
use ascend_rs_builder::KernelBuilder;
use std::path::PathBuf;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    println!("cargo:rerun-if-changed=kernels");
    ascend_rs_builder::add_ascend_link_args()?;

    let out_path = PathBuf::from(std::env::var("OUT_DIR").unwrap());
    let kernel = out_path.join("kernel.o");

    // 检测到 "kernels" 是目录 → 触发 Rust 内核编译流水线
    KernelBuilder::new("kernels").copy_to(&kernel).build()?;
    Ok(())
}

当 KernelBuilder 检测到输入是一个目录（包含 Cargo.toml），它会：

以 davinci-huawei-none 为目标运行 cargo build
指定 -Zcodegen-backend=rustc_codegen_mlir 使用自定义代码生成后端
后端将 Rust MIR 翻译为 MLIR
mlir_to_cpp 步骤将 MLIR 转换为带有 AscendC API 调用的 C++ 源码（DMA、向量操作、流水线同步）
调用 bisheng（CANN C++ 编译器）将生成的 C++ 编译为 NPU 二进制（.acl.o）

第 4–5 步是关键：尽管 CANN 提供了 bishengir-compile（910B 的 MLIR 原生编译器），但生产流水线对所有目标（310P 和 910B）均使用 mlir_to_cpp 路径。这条 C++ 代码生成路径提供了完整的 AscendC 特性支持——通过 DataCopy 实现 DMA 操作、TPipe 基础设施和向量指令。当 Rust 内核调用 ascend_reduce_max_f32 等函数时，mlir_to_cpp 步骤在 MLIR 中识别这些调用，并生成对应的 AscendC 向量操作（ReduceMax、Exp 等）。在 910B3 硬件上通过验证的全部 522 个测试均采用此路径。

4. 更真实的示例：Softmax

向量乘法展示了基本功能，但实际的神经网络负载需要 exp()、log()、sqrt() 等数学函数。Softmax 函数——广泛应用于注意力层、分类头和概率归一化——是一个很好的例子：

$$\text{softmax}(x_i) = \frac{e^{x_i - \max(x)}}{\sum_j e^{x_j - \max(x)}}$$

4.1 `ascend_std` 中的数学内建函数

ascend-rs 将硬件数学运算暴露为原始类型上的 Rust 方法。底层实现中，f32::exp() 映射到 expf32 编译器内建函数，MLIR 代码生成后端将其降低为 llvm.intr.exp——最终作为 NPU 原生数学指令执行。

// 在 ascend_std 中：这些方法在内核代码中可用于 f32/f64
let y = x.exp();   // expf32 → llvm.intr.exp
let y = x.ln();    // logf32 → llvm.intr.log
let y = x.sqrt();  // sqrtf32 → llvm.intr.sqrt

4.2 Softmax 内核

以下是用 Rust 编写的完整 Softmax NPU 内核：

#![feature(no_core)]
#![no_std]
#![no_core]

#[ascend_std::aiv_kernel]
pub unsafe fn softmax(input: *const f32, output: *mut f32, len: *const u32) {
    unsafe {
        let n = *len as usize;

        // 第一步：找到最大值，用于数值稳定性
        let mut max_val = *input;
        let mut i = 1usize;
        loop {
            if i >= n { break; }
            let val = *input.wrapping_add(i);
            if val > max_val { max_val = val; }
            i = i + 1;
        }

        // 第二步：计算 exp(x_i - max) 并累加求和
        let mut sum: f32 = 0.0;
        i = 0;
        loop {
            if i >= n { break; }
            let exp_val = (*input.wrapping_add(i) - max_val).exp();
            *output.wrapping_add(i) = exp_val;
            sum = sum + exp_val;
            i = i + 1;
        }

        // 第三步：归一化
        i = 0;
        loop {
            if i >= n { break; }
            *output.wrapping_add(i) = *output.wrapping_add(i) / sum;
            i = i + 1;
        }
    }
}

关键的一行是 (*input.wrapping_add(i) - max_val).exp()——它调用 f32::exp()，通过 MLIR 后端编译为 NPU 原生指数指令。在求指数之前减去 max_val 是标准的数值稳定性技巧，可以防止溢出。

这证明了 ascend-rs 内核代码不仅限于简单的算术运算——它可以表达与 C++ AscendC 相同的算法，同时享有 Rust 的安全保障。

4.3 性能对比：Rust vs C++（真实硬件测试）

Rust 内核在真实 NPU 硬件上的性能如何？我们在昇腾 310P NPU 上使用四种实现方式对 softmax 进行了基准测试：

C++ 朴素（标量）——手写的 C++ 内核，使用标量循环和 GetValue/SetValue 访问器
C++ 优化（向量）——专家编写的 C++ 内核，使用 AscendC 向量指令（ReduceMax、Exp、Muls）
Rust 标量——上述 Rust 内核，通过 MLIR-to-C++ 代码生成流水线编译
Rust 向量——使用 ascend-rs 向量指令（ascend_reduce_max_f32、ascend_exp_f32、ascend_muls_f32）的 Rust 内核，通过同一流水线编译

每个内核处理 f32 输入数组，每种配置进行 1 次预热和 10 次计时。所有结果均与 CPU 参考进行正确性验证。

大小	C++ 朴素 (ms)	C++ 优化 (ms)	Rust 标量 (ms)	Rust 向量 (ms)	标量 vs 朴素	向量 vs 优化
256	0.100	0.078	0.099	0.077	0.99x	0.99x
1,024	0.191	0.077	0.202	0.076	1.06x	0.99x
4,096	0.568	0.079	0.607	0.079	1.07x	1.00x
16,384	2.073	0.089	2.221	0.087	1.07x	0.98x

关键发现：

Rust 向量内核完全匹配 C++ 优化性能。 使用 ascend_std 向量指令（映射到 AscendC 操作）的 Rust 向量化内核，在所有大小下的性能与手工优化的 C++ 内核相差在 1-2% 以内。在 16,384 元素时，Rust 向量内核（0.087ms）甚至略快于 C++ 优化（0.089ms）。这意味着用 Rust 编写向量化 NPU 内核不会带来任何性能损失。
向量指令带来巨大的性能提升。 两种向量化内核在小数据量时快 1.3 倍，在 16,384 元素时快达 25 倍。向量流水线每周期处理 256 位（8 个 float），而标量每周期只处理 1 个元素。
Rust 标量性能达到 C++ 标量的 93-100%。 标量代码生成路径同样产生有竞争力的代码，微小的开销来自不同的 UB 访问模式（直接指针算术 vs 访问器方法）。
所有实现数值正确。 每种内核-大小组合的输出均与 CPU 参考匹配（最大误差 < 1e-8，输出总和 ≈ 1.0）。向量化实现因使用硬件优化的数学运算，误差甚至更低（~1e-10 vs ~1e-8）。

下面是 Rust 向量化 softmax 内核的代码——与 C++ 版本几乎完全对应：

#[ascend_std::aiv_kernel]
pub unsafe fn softmax(input: *const f32, output: *mut f32, len_buf: *const u32) {
    unsafe {
        let n = *len_buf;
        let in_buf  = ascend_std::ascend_buf_alloc(n);
        let out_buf = ascend_std::ascend_buf_alloc(n);
        let work    = ascend_std::ascend_buf_alloc(n);
        let rwork   = ascend_std::ascend_buf_alloc(n);

        ascend_std::ascend_buf_load_f32(in_buf, input, n);
        ascend_std::ascend_pipe_barrier();

        let max_val = ascend_std::ascend_reduce_max_f32(work, in_buf, rwork, n);
        ascend_std::ascend_adds_f32(out_buf, in_buf, 0.0f32 - max_val, n);
        ascend_std::ascend_exp_f32(out_buf, out_buf, n);
        let sum_val = ascend_std::ascend_reduce_sum_f32(work, out_buf, rwork, n);
        ascend_std::ascend_muls_f32(out_buf, out_buf, 1.0f32 / sum_val, n);

        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_buf_store_f32(output, out_buf, n);
    }
}

ascend_buf_alloc / ascend_buf_load_f32 / ascend_reduce_max_f32 等调用是 ascend_std 中的 extern "C" 声明，MLIR 代码生成后端在 C++ 代码生成阶段将其识别并转换为 AscendC API 调用（TBuf、DataCopy、ReduceMax 等）。这使得 Rust 内核可以直接访问 NPU 的向量流水线，且没有额外开销。

4.4 不止于 Softmax：激活函数基准测试

为了验证向量指令 API 的广度，我们对另外三个激活函数——Relu、Sigmoid 和 Tanh——进行了基准测试，它们均由相同的基础向量操作组合而成。与 softmax 不同，这些激活函数没有专用的 AscendC 内建函数，而是通过可组合的向量原语构建：

Relu(x) = max(x, 0) → Maxs
Sigmoid(x) = 1 / (1 + exp(-x)) → Muls → Exp → Adds → Reciprocal
Tanh(x) = 2 · sigmoid(2x) - 1 → Muls → Exp → Adds → Reciprocal → Muls → Adds

对于每个函数，我们比较 C++ 实现（TQue 流水线）和等效的 Rust 风格代码（TBuf 流水线，与 mlir_to_cpp 输出一致）：

大小	Relu C++ (ms)	Relu Rust (ms)	Sigmoid C++ (ms)	Sigmoid Rust (ms)	Tanh C++ (ms)	Tanh Rust (ms)
256	0.078	0.075	0.075	0.075	0.075	0.077
1,024	0.075	0.076	0.075	0.074	0.075	0.076
4,096	0.075	0.076	0.077	0.077	0.076	0.078
16,384	0.083	0.083	0.086	0.086	0.085	0.086

六个内核的性能在测量噪声范围内完全一致。Relu 实现了精确正确性（max_err = 0），Sigmoid 和 Tanh 在大小 ≥ 1024 时 max_err < 3e-3。size=256 的精度问题在 C++ 和 Rust 上同样存在——这是 AscendC 在小向量尺寸下的硬件级精度特征，而非代码生成问题。

这证实了 Rust 向量指令 API 的通用性不局限于 softmax。对于此处测试的激活函数——每个都是 AscendC 向量原语的组合——Rust 与 C++ 产生了相同的性能。我们预期这一结论对所有纯向量指令组合的内核都成立，因为代码生成器将每个 Rust 指令调用 1:1 映射到相同的 AscendC C++ 调用。Cube 引擎操作（通过 Mmad 的矩阵乘法）和多层缓冲区层次（L1/L0A/L0B/L0C）在 API 层面已支持，但尚未通过完整流水线进行硬件验证。

4.5 形式化等价验证：AscendC 与 AscendRS

性能持平固然令人信服，但 Rust 代码生成管线最有力的论据是逐位等价——证明 Rust 生成的内核在真实 NPU 硬件上产生与手写 AscendC C++ 内核完全相同的数值结果。

我们选择了三个代表性内核，覆盖最常见的神经网络算子模式：

ReLU — 单一向量操作：output[i] = max(input[i], 0) → ascend_maxs_f32
Sigmoid — 链式向量操作：output[i] = 1/(1 + exp(-input[i])) → Muls → Exp → Adds → Reciprocal
Vec Add — 二元向量操作：z[i] = x[i] + y[i] → ascend_add_f32

对于每个内核，我们编译了两种实现：

AscendC 原版 — 使用 TQue 流水线（EnQue/DeQue 隐式同步）的惯用 C++ 写法，即 910B 生产工程师通常使用的方式
AscendRS 等价版 — 从 Rust 源码经 mlir_to_cpp 管线生成的 C++（TBuf + 显式 pipe_barrier(PIPE_ALL)）

两者在 310P NPU 上使用相同输入（256 个 f32 元素，确定性 PRNG）运行，并在三个层面进行比较：

测试	C++ vs CPU	RS vs CPU	C++ vs RS
ReLU	PASS (err=0.00)	PASS (err=0.00)	PASS (err=0.00)
Sigmoid	PASS (err=2.4e-3)	PASS (err=2.4e-3)	PASS (err=0.00)
Vec Add	PASS (err=0.00)	PASS (err=0.00)	PASS (err=0.00)

C++ vs RS 列显示所有三个内核的输出逐位完全相同（最大误差 = 0.0）。无论内核是用 C++ 还是 Rust 编写，NPU 产生的结果完全一致。Sigmoid 与 CPU 的微小差异（2.4e-3）源于 NPU 向量单元 Exp() 与 x86 expf() 的精度差异——两种实现同样受到影响，并非代码生成问题。

以下是 Rust sigmoid 内核——四行向量指令调用即可产生与 40 行 AscendC C++ 类完全相同的 NPU 输出：

#[ascend_std::aiv_kernel]
pub unsafe fn sigmoid(input: *const f32, output: *mut f32, len: *const u32) {
    unsafe {
        let n = *len;
        let buf_in = ascend_std::ascend_buf_alloc(n);
        let buf_out = ascend_std::ascend_buf_alloc(n);

        ascend_std::ascend_buf_load_f32(buf_in, input, n);
        ascend_std::ascend_pipe_barrier();

        ascend_std::ascend_muls_f32(buf_out, buf_in, -1.0f32, n);
        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_exp_f32(buf_out, buf_out, n);
        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_adds_f32(buf_out, buf_out, 1.0f32, n);
        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_reciprocal_f32(buf_out, buf_out, n);

        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_buf_store_f32(output, buf_out, n);
    }
}

在此工作中的一个重要发现：310P 上的原地链式向量操作需要在每一步之间显式添加 pipe_barrier(PIPE_ALL)。 如果在同一缓冲区上的 Muls→Exp→Adds→Reciprocal 操作之间缺少屏障，下一个操作将读取过期数据。这是一个硬件同步要求，Rust 代码生成管线现已正确处理——等价测试同时也是该行为的回归测试。

4.6 双缓冲结果（910B2，2026-04-02）

§4.3–4.5 的单 tile softmax 大部分挂钟时间都在等一次 DMA 完成、下一步计算才能开始。教科书式的修复就是双缓冲：先连续发出两个 tile load，再在第一个上做计算，同时第二个的 DMA 仍在路上。Rust tile API 用四行序言表达这个意思——tile 0 用 tile_load_f32，tile 1 用 tile_prefetch_f32——mlir_to_pto 把它们各自降为带不同 partition_view 行偏移的 pto.tload，这正是 ptoas 把两次 DMA 同时调度到 Mte2 流水线所需要的信号。

变体（1×1024 f32, 910B2）	per-tile 最小	per-tile 平均	相对单 tile 加速
单 tile（PTO，§4.3）	4.0 µs	4.6 µs	1.00×（基线）
双缓冲（2 tile）	2.4 µs	3.4 µs	1.65×–1.35×

数值与单 tile 路径一致：max_err = 3.26e-9，sum 与 1.0 在一个 ulp 之内。完整复现——内核源码、生成的 PTO-MLIR（带两个不同行偏移的 partition_view）、构建/运行命令——见附录 J §J4。

让这个例子能跑起来所做的两个 bug 修复——make_pv 没有把 GEP offset 传下去、Pattern 3 把 alias 链拍平了——文档化在该附录示例的末尾。双缓冲是把这两个 bug 暴露出来的测试用例，因为只有当两个不同 offset 的 partition_view 共存于同一内核时它们才有影响。

4.7 通过 linalg 桥导入上游 MLIR 的 Softmax

到目前为止，本章的每个 softmax 内核都从 Rust 源码出发。同样的内核也可以从相反方向到达 NPU：用标准的上游 linalg 方言写在别处，经 ascend-rs 的 linalg 桥摄入，然后输出到与从 Rust 经 mlir_to_cpp 生成的同一份 AscendC C++。这座桥让 ascend-rs 能吸纳第三方前端的内核——torch-mlir、iree、上游 MLIR 测试中手写的 linalg——而不必在 ascend_std 里再写一遍。

上游形式只有两行：

// benchmarks/linalg/kernels_upstream_shape_matched/softmax_upstream_1x1024.mlir
func.func @upstream_softmax_1x1024(%arg0: tensor<1x1024xf32>) -> tensor<1x1024xf32> {
  %0 = tensor.empty() : tensor<1x1024xf32>
  %1 = linalg.softmax dimension(1) ins(%arg0 : tensor<1x1024xf32>)
                                   outs(%0   : tensor<1x1024xf32>) -> tensor<1x1024xf32>
  return %1 : tensor<1x1024xf32>
}

linalg_to_ascend_tile 把 linalg.softmax 改写成与 Rust 前端发出的同一组 ascend_tile_* intrinsic 调用序列，因此从那一点之后下游管线逐字节相同：mlir_to_cpp 产生的 AscendC C++ 与从手写 ascendrs-form 内核生成的版本相差零字节。

摄入路径在 2026-04-22 验证（910B2，chip 0/2，3 次重复）：

Pair（1×1024 f32）	来源	NPU 最小 (µs)	Δ vs 手写	一致
add	upstream linalg	~5.0	≤ 0.4 µs（约 5%）	✓
add	torch-mlir FX	~4.2	0.02–0.48 µs	✓
exp	upstream linalg	~4.6	≤ 0.1 µs（<2%）	✓
exp	torch-mlir FX	~4.5	0.08–0.26 µs	✓
softmax	upstream linalg	~5.2	≤ 0.4 µs（<8%）	✓
matmul 32×64×32	upstream linalg	1586	< 0.3 µs（<0.02%）	✓

matmul 那一行是决定性的：在 1.58 ms/次的尺度下，AclEvent 计时器的噪声底约为运行时的 0.1%，所以三次重复中 min/p50/mean 全部一致就是真正的数值等价——而非测量不确定。对 softmax 来说，AscendC 输出逐字节相同，意味着任何吞吐差异只能来自编译器缓存或 DMA 调度，而 bench 中没有看到任何可测的差。

这对运行示例意味着什么。 本章的 softmax 现在已经走过三条路径到达同一颗 910B2 芯片：

(a) Rust 标量      ─┐
(b) Rust 向量      ─┼─ rustc + mlir_to_cpp ──── AscendC ─── bisheng ── 910B2
(c) Rust tile API  ─┘                ─── mlir_to_pto ─── ptoas ─── ccec ─── 910B2

(d) upstream linalg ─── linalg_to_ascend_tile ─── mlir_to_cpp ─── AscendC ── 910B2
(e) torch-mlir FX   ─── linalg_to_ascend_tile ─── mlir_to_cpp ─── AscendC ── 910B2

(d) 与 (e) 复用 (b) 的同一个 emitter。这里的「零开销」并非基准技巧——它是桥的结构性属性：摄入把 linalg 降到 ascend_tile，再调用 Rust 前端调用的同一个 emitter。已经没有地方留给「慢」躲藏。

复现脚本在附录 J §J5。

下面这段 30 秒走查在 adablue 上把四条路径连续过了一遍。每个阶段打印源码、跑宿主侧那一步（或展示已提交的 artifact）、再打印 emit 的前几行——重点是路径 (a)、(b)、(e) 全都汇合到同一份 mlir_to_cpp emit，而路径 (c) 走平行的 mlir_to_pto + ptoas 通路：

ch04 softmax — 四条路径在 mlir_to_cpp 汇合

4.8 跨管线安全：同一个 Oracle 守护全部五条路径

加入摄入路径 (d) 与 (e) 引出一个诚实的问题：本章的每条 Rust 路径都经过 rustc 前端，已经做过类型检查、借用检查、并通过第 11 章的安全 Oracle 静态检视过摆位与别名 bug。从 linalg 桥到达的内核完全跳过 Rust。它们能拿到同样的安全分析吗？

答案是肯定的——把同一个 Oracle 跑在桥的中间形式上即可。第 12 章描述两种接线：

Path A 把 ascend_tile MLIR（桥的中间形式，hop 1 之后）投影成一个 stage-2 Plan，并在其上跑第 11 章六个 pass 中的五个。上文那个 softmax fixture 投影出的 plan 是干净的。
Path C 把同一个内核经 mlir_to_pto → ptoas --print-after-all 进一步降低，解析 PlanMemoryPass 之后的 MLIR，并对其跑全部六 pass。干净的 softmax 仍然干净；注入 dead-tile 的变体在 Path A 投影器看不到的「分块后」那一层被 capacity 检查抓住。

这种对比——同一份 .acl.pto softmax，同一个 ptoas，Oracle 给出两种结果——就是录制在§11.6中的那段 demo。把桥接到 ACLRS_LINALG_SAFETY=path-a（或 path-c）之后，一个本会在运行时悄悄破坏 VEC 的上游 linalg 内核，会在到达 bisheng 之前就成为编译期发现。

5. 规模化：覆盖 MultiKernelBench 全部类别的 502 个内核

在单一基准测试和等价验证之外，我们系统性地扩展了 ascend-rs 的内核覆盖范围，实现了对 MultiKernelBench 基准套件全部 300 个 PyTorch 参考内核的完整 1:1 覆盖，涵盖 17 个类别（激活函数、网络架构、注意力机制、广播运算、卷积、融合算子、索引操作、损失函数、数学运算、矩阵乘法、归一化、优化器、池化、归约、缩放、分块、多核）。

ascend-rs 目前包含 1565 个 Rust NPU 内核，全部可通过 MLIR 代码生成后端编译。这些内核按验证层级分为以下级别：

16 个可部署内核 — 通过完整的 Rust→MLIR→C++→bisheng 流水线编译，已部署到 NPU 硬件上执行
413 个测试在 Ascend 910B3 上通过 NPU 正确性验证 — 在真实硬件上与 CPU 参考验证，0 失败、0 崩溃；代表性内核（第 4.5 节）与手写 AscendC C++ 逐位相同。包含 34 个矩阵乘法测试通过 CANN 的 aclnn 算子 API（aclnnMm、aclnnAdd、aclnnAddmm、aclnnRelu、aclnnMul、aclnnReduceSum）执行，以及全部卷积、池化、缩放、索引和优化器内核
489 个编译测试内核 — 已验证可通过 MLIR 后端编译并通过 CPU 级正确性测试

Cube 引擎矩阵乘法内核——此前因混合 AIV/AIC 二进制中 TPipe L1/CBUF 队列分配问题而受阻——现已通过 CANN 内置算子 API 正确执行。两阶段 aclnn 算子模式（GetWorkspaceSize + Execute）从 libopapi.so 动态加载，完全绕过自定义内核编译，利用 Cube 引擎的内置优化算子。组合算子链（如 aclnnMm + aclnnRelu + aclnnAdd 实现 ResNet 残差块）使融合矩阵乘法变体得以实现，否则需要自定义 Cube 内核开发。

类别	内核数	实现方式
激活函数 (16)	relu、sigmoid、gelu、tanh、softmax、elu、selu、swish、mish、softplus、softsign、hardsigmoid、hardswish、leaky_relu、log_softmax、gelu_tanh	向量指令 + `kernel_ops` 组合算子
网络架构 (41)	AlexNet/VGG/ResNet 全连接层、DenseNet 块、MobileNet/EfficientNet、ViT/Swin MLP、MinGPT、LSTM 门控/单元、GRU 门控、Mamba SSM	矩阵乘法 + 激活 + 归一化组合
注意力机制 (15)	缩放点积、因果、交叉、多查询、分组查询、KV 缓存、跨模态、线性、稀疏、窗口因果、SwiGLU、GeGLU、掩码填充	缩放 + 掩码 + softmax 模式
广播运算 (8)	add_bias、逐元素乘/除/减/最大/最小、clamp、平方	二元向量指令
卷积 (34)	标准 conv2d、深度可分离 conv2d、转置 conv2d 变体	标量嵌套循环（不使用 Cube 引擎）
融合算子 (86)	matmul+gelu、gemm+relu+divide、norm+激活、多算子链（3-6 个算子融合）	链式向量指令 + 流水线屏障
索引操作 (12)	gather、scatter、scatter_add、index_select、index_copy、index_add、embedding、masked_fill、inplace_update、take_along_dim	标量嵌套循环 + 边界检查索引
损失函数 (6)	MSE、Huber、hinge、余弦相似度、交叉熵、KL 散度	归约 + 算术
数学运算 (5)	累积和（3 种变体）、累积积、矩阵标量乘法	标量循环 + 向量操作
矩阵乘法 (17)	标准、批量、对称、带偏置、缩放、GEMM、宽矩阵、累加、对角缩放、外积	Cube 引擎（Mmad FFI）
归一化 (9)	layernorm、rmsnorm、batch/group/instance norm、L1/L2/Frobenius 范数	归约 + 归一化模式
优化器 (6)	SGD、SGD+动量、Adagrad、RMSprop、Adam、扩展变体	原地缓冲区算术
池化 (6)	全局平均/最大/最小池化、融合池化+sigmoid、LP 池化	基于归约
归约 (5)	最大、最小、求和、均值、乘积	硬件归约指令
缩放 (5)	最近邻、线性插值、双三次权重、加权求和、三线性	插值算术
分块 (16)	256 元素分块的激活函数和运算变体	循环 + 分块缓冲区分配
多核 (16)	AICore 块级并行变体	`get_block_idx()` 工作分配

为支持这一广度，我们在 kernel_ops.rs 中新增了 17 个组合算子——如 elu_f32、mish_f32、rms_norm_f32、mse_loss_f32 和 cosine_similarity_f32——每个都由基础向量指令组合而成，并正确放置流水线屏障。

卷积和索引/gather/scatter 类别通过标量嵌套循环模式实现，在 API 层面达成 MultiKernelBench 的完整覆盖。CPU 正确性测试（cargo test -p kernel_correctness）验证了涵盖所有类别的 80 个代表性内核的数值精度。其余编译测试验证了通过 MLIR 后端的成功编译，但未进行 CPU 级数值检查。

进度报告 — 截至当前代码库的验证状态（通过 count_kernels.sh 和硬件测试日志确认）：

验证层级	数量	说明
编译测试通过	489	通过 MLIR 后端编译 + CPU 级正确性（`cargo test -p compiletest`）
910B3 正确性验证	413	在 Ascend 910B3 上通过 NPU 正确性测试（0 失败、0 崩溃）；包含 34 个矩阵乘法（aclnn）、全部卷积/池化/缩放/索引/优化器内核
与 AscendC 性能对等	4	开销 ≤2%（第 4.3–4.4 节）：softmax、relu、sigmoid、tanh
可部署（完整流水线）	16	通过 Rust→MLIR→C++→bisheng 编译并在 NPU 上执行
内核总数	1565	全部可通过 MLIR 代码生成后端编译

522 个通过 NPU 正确性测试的测试覆盖所有内核类别：向量指令内核（激活函数、归约、融合算子链、多核并行）、Cube 引擎矩阵乘法（通过 aclnn 算子组合）、卷积、池化、缩放、索引操作和优化器——0 失败、0 崩溃。

6. 内存安全案例研究：AscendC C++ vs ascend-rs

在 16 个内核部署到 NPU 硬件、413 个测试在 Ascend 910B3 上通过 NPU 正确性验证、1565 个总计内核通过 MLIR 后端编译之后，ascend-rs 的价值主张超越了性能对等——核心优势在于内存安全。以下我们展示 6 组配对的案例研究，每组中 AscendC C++ 内核包含一个真实的、可被利用的内存安全漏洞，而等价的 Rust ascend-rs 内核从结构上阻止了同类漏洞。

这些不是刻意构造的示例。每种漏洞类别都是 AscendC C++ 内核开发实践中真实存在的模式：

案例	漏洞类型	C++ 根本原因
1. 类型混淆	`GM_ADDR` 擦除所有类型信息	函数签名编码元素类型
2. 缓冲区溢出	`GetValue(i)`/`SetValue(i,v)` 无边界检查	基于 Buffer-ID 的 API + 显式计数参数
3. 释放后使用	`FreeTensor()` 后通过失效句柄访问	API 中无手动释放操作
4. 缺失同步	忘记在 DMA 和计算之间添加 `pipe_barrier()`	`kernel_ops` 组合算子内置屏障
5. 双重释放	`FreeTensor()` 被调用两次	API 中不存在释放操作
6. 整数溢出	偏移量计算中 `u32` 静默回绕	`wrapping_mul` 使溢出语义显式化

6.1 类型混淆：GM_ADDR 类型擦除

AscendC 内核入口点将所有张量指针作为 GM_ADDR（= uint8_t*）接收。内核必须手动转换为正确的元素类型。如果宿主机传入 f16 数据但内核转换为 float*，每个元素读取 4 字节而非 2 字节——产生垃圾值且无任何警告。当一个内核在不同数据类型之间复用而未更新类型转换时，或者当宿主机封装传入了错误的张量格式时，就会触发此漏洞。

C++ — 存在漏洞：

#include "kernel_operator.h"

class KernelSoftmaxConfused {
public:
    __aicore__ inline void Init(GM_ADDR input, GM_ADDR output, GM_ADDR len_buf) {
        uint32_t n = *((__gm__ uint32_t *)len_buf);

        // BUG: 宿主机传入了半精度 (f16) 数据，但我们转换为 float。
        // 每个 "float" 元素读取 4 字节而非 2 字节，因此：
        //   - 有意义的值只有预期数量的一半
        //   - 每个值都是垃圾（两个 f16 位模式被重新解释为一个 float）
        // 编译器无法捕获此问题，因为 GM_ADDR 只是 uint8_t*。
        inputGm.SetGlobalBuffer((__gm__ float *)input, n);
        outputGm.SetGlobalBuffer((__gm__ float *)output, n);
        // ...
    }

    __aicore__ inline void Compute(int32_t len) {
        AscendC::LocalTensor<float> xLocal = inQueue.DeQue<float>();
        AscendC::LocalTensor<float> yLocal = outQueue.AllocTensor<float>();
        // 所有计算都在垃圾值上操作——静默产生错误输出，无崩溃、无报错。
        AscendC::Exp(yLocal, xLocal, len);
        outQueue.EnQue<float>(yLocal);
        inQueue.FreeTensor(xLocal);
    }
    // ...
};

// 入口点使用 GM_ADDR (= uint8_t*) 接收所有张量参数。
// 调用方可以传入任何数据类型——此边界没有类型检查。
extern "C" __global__ __aicore__ void softmax_confused(
        GM_ADDR input, GM_ADDR output, GM_ADDR len_buf) {
    KernelSoftmaxConfused op;
    op.Init(input, output, len_buf);
    op.Process();
}

/// 签名 `input: *const f32` 意味着宿主机必须传入 f32 张量。
/// 如果宿主机有 f16 数据 (*const u16)，调用此函数是类型错误：
///     softmax(f16_ptr, ...)  // 错误：期望 *const f32，实际 *const u16
#[ascend_std::aiv_kernel]
pub unsafe fn softmax(input: *const f32, output: *mut f32, len: *const u32) {
    unsafe {
        let n = *len;
        let buf_in = ascend_std::ascend_buf_alloc(n);
        let buf_out = ascend_std::ascend_buf_alloc(n);
        let buf_work = ascend_std::ascend_buf_alloc(n);

        // 加载 f32 数据——_f32 后缀与指针类型匹配。
        // 不可能通过 f32 API 意外加载 f16 数据。
        ascend_std::ascend_buf_load_f32(buf_in, input, n);
        ascend_std::ascend_pipe_barrier();

        // softmax_f32 期望 f32 缓冲区——整个流水线中类型一致性
        // 无需手动转换即可保持。
        ascend_std::kernel_ops::softmax_f32(buf_out, buf_in, buf_work, n);

        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_buf_store_f32(output, buf_out, n);
    }
}

核心洞见： 在 C++ 中，GM_ADDR 是类型擦除的 uint8_t*，接受任何数据格式。在 Rust 中，函数签名 *const f32 是类型系统的一部分——编译器在编译期拒绝类型不匹配。

6.2 缓冲区溢出：未检查的张量索引

AscendC 的 GetValue(i) 和 SetValue(i, v) 不执行边界检查。如果循环边界错误——off-by-one 错误、使用了错误的长度变量、或混淆了输入/输出大小——内核会在本地 SRAM 上越界读写。由于本地 SRAM 在同一 tile 内的所有张量分配之间共享，越界写入会静默覆盖相邻张量的数据。

C++ — 存在漏洞：

#include "kernel_operator.h"

class KernelScalarSoftmax {
    // ...
    __aicore__ inline void Compute(int32_t len, int32_t alignedLen) {
        AscendC::LocalTensor<float> xLocal = inQueue.DeQue<float>();
        AscendC::LocalTensor<float> yLocal = outQueue.AllocTensor<float>();

        // 第一步：找最大值（标量循环）
        float maxVal = xLocal.GetValue(0);
        for (int32_t i = 1; i < len; i++) {
            float v = xLocal.GetValue(i);
            if (v > maxVal) maxVal = v;
        }

        // 第二步：计算 exp(x - max) 并求和
        float sum = 0.0f;
        for (int32_t i = 0; i < len; i++) {
            float v = xLocal.GetValue(i) - maxVal;
            yLocal.SetValue(i, v);
            sum += v;
        }

        // 第三步：归一化
        float invSum = 1.0f / sum;

        // BUG: Off-by-one 错误——循环条件使用 <= 而非 <。
        // 当 i == len 时，SetValue 写入超出已分配缓冲区一个元素。
        // 这会覆盖 SRAM 中的相邻数据（另一个张量的数据、
        // 队列元数据等），且无错误或警告。
        for (int32_t i = 0; i <= len; i++) {  // 应为 i < len
            yLocal.SetValue(i, yLocal.GetValue(i) * invSum);  // i==len 时越界
        }

        outQueue.EnQue<float>(yLocal);
        inQueue.FreeTensor(xLocal);
    }
    // ...
};

        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_buf_store_f32(output, buf_out, n);
    }
}

核心洞见： C++ API 暴露了无边界检查的 GetValue(i)/SetValue(i, v)——off-by-one 错误的经典来源。Rust 的 Buffer-ID API 使用显式计数参数对整个缓冲区操作，完全消除了逐元素索引。

6.3 释放后使用 LocalTensor

AscendC 要求手动调用 FreeTensor() 将 SRAM 缓冲区归还到队列的空闲池。调用 FreeTensor() 后，LocalTensor 句柄在 C++ 类型层面仍然有效——它仍持有原始缓冲区地址。任何后续的 GetValue() 或 SetValue() 都能编译并运行，但读写的内存可能已被重新分配给其他张量。

C++ — 存在漏洞：

class KernelVecAddUAF {
    // ...
    __aicore__ inline void Compute(int32_t len) {
        AscendC::LocalTensor<half> xLocal = inQueueX.DeQue<half>();
        AscendC::LocalTensor<half> yLocal = inQueueY.DeQue<half>();
        AscendC::LocalTensor<half> zLocal = outQueueZ.AllocTensor<half>();

        AscendC::Add(zLocal, xLocal, yLocal, len);

        // 将缓冲区归还到空闲池
        inQueueX.FreeTensor(xLocal);
        inQueueY.FreeTensor(yLocal);

        // BUG: xLocal 已在上面被释放，但 C++ 句柄仍能编译。
        // SRAM 区域已归还到 inQueueX 的空闲列表。
        // 在多 tile 内核中，此缓冲区可能已被下一次迭代的
        // AllocTensor() 重新分配。读取返回过期或损坏的数据。
        half check = xLocal.GetValue(0);  // 释放后使用！

        // 过期值可能导致错误的控制流决策
        if ((float)check > 100.0f) {
            AscendC::Muls(zLocal, zLocal, (half)0.5f, len);  // 基于垃圾数据
        }

        outQueueZ.EnQue<half>(zLocal);
    }
    // ...

核心洞见： C++ 的 LocalTensor 句柄在 FreeTensor() 之后在语法上仍然有效——编译器无法区分已释放和存活的句柄。在 Rust 中，Buffer ID 是 #[repr(transparent)] 新类型封装（UbBuf、L1Buf、L0aBuf、L0bBuf、L0cBuf），没有释放操作；“在释放后使用缓冲区“不是一个有意义的概念。新类型还防止将缓冲区传递到错误的存储层级——例如，将 L0aBuf 传递给期望 UbBuf 的向量操作会导致编译错误。

6.4 缺失流水线同步

昇腾 NPU 并发执行 DMA（MTE2/MTE3）、向量（V）和标量（S）流水线。在 DMA 加载和后续向量操作之间需要 pipe_barrier() 来确保数据确实已到达本地 SRAM。忘记此屏障是最常见的 NPU 漏洞——内核正常编译和运行，但产生静默的错误结果。

C++ — 存在漏洞：

#include "kernel_operator.h"

class KernelSigmoidNoSync {
    // ...
    __aicore__ inline void CopyIn(int32_t offset, int32_t len) {
        AscendC::LocalTensor<float> xLocal = inQueue.AllocTensor<float>();
        AscendC::DataCopy(xLocal, inputGm[offset], len);
        // BUG: DMA 加载和 EnQue 之间缺少 pipe_barrier()。
        // EnQue 只是将张量标记为队列中"可用"，
        // 但不保证 DMA 传输已完成。
        // 如果 DMA 流水线 (MTE2) 比标量流水线 (S) 慢，
        // 后续的 DeQue + 向量操作将读取过期的 SRAM 数据。
        inQueue.EnQue(xLocal);
    }

    __aicore__ inline void Compute(int32_t len) {
        AscendC::LocalTensor<float> xLocal = inQueue.DeQue<float>();
        AscendC::LocalTensor<float> yLocal = outQueue.AllocTensor<float>();

        // Sigmoid = 1 / (1 + exp(-x))
        // 每个向量操作都可能在 DMA 加载完成之前执行，
        // 读取未初始化或过期的 SRAM 数据。
        AscendC::Muls(yLocal, xLocal, -1.0f, len);       // -x（过期数据？）
        AscendC::Exp(yLocal, yLocal, len);                // exp(-x)
        AscendC::Adds(yLocal, yLocal, 1.0f, len);         // 1 + exp(-x)
        AscendC::Reciprocal(yLocal, yLocal, len);          // 1 / (1 + exp(-x))

        outQueue.EnQue<float>(yLocal);
        inQueue.FreeTensor(xLocal);
    }
    // ...
};

        // 所有内部屏障已包含——不可能遗忘。
        ascend_std::kernel_ops::sigmoid_f32(buf_out, buf_in, n);

        // 显式屏障：保证向量计算完成后才有 DMA 存储读取 buf_out。
        ascend_std::ascend_pipe_barrier();

        // 从 UB 存储数据到 GM
        ascend_std::ascend_buf_store_f32(output, buf_out, n);
    }
}

核心洞见： C++ 的队列模型（EnQue/DeQue）给人同步的假象，但实际并不确保 DMA 完成。在 Rust 中，每个屏障都是显式的（ascend_pipe_barrier()），且 kernel_ops 组合算子包含所有内部屏障——程序员不可能在组合操作内部意外遗漏屏障。

6.5 双重释放张量缓冲区

对同一 LocalTensor 调用两次 FreeTensor() 会将同一缓冲区地址两次插入队列的空闲列表。接下来的两次 AllocTensor() 调用都会返回相同的缓冲区，导致两个“不同“的张量别名同一 SRAM 区域。这表现为间歇性的数据损坏，且依赖于 tile 数量。

C++ — 存在漏洞：

#include "kernel_operator.h"

class KernelVecAddDoubleFree {
    // ...
    __aicore__ inline void Compute(int32_t len) {
        AscendC::LocalTensor<half> xLocal = inQueueX.DeQue<half>();
        AscendC::LocalTensor<half> yLocal = inQueueY.DeQue<half>();
        AscendC::LocalTensor<half> zLocal = outQueueZ.AllocTensor<half>();

        AscendC::Add(zLocal, xLocal, yLocal, len);

        inQueueX.FreeTensor(xLocal);
        inQueueY.FreeTensor(yLocal);
        outQueueZ.EnQue<half>(zLocal);

        // BUG: 重构时的复制粘贴错误——FreeTensor 被再次调用。
        // xLocal 的缓冲区现在在 inQueueX 的空闲列表中出现两次。
        // 在接下来的两次 tile 迭代中，AllocTensor 将为两个"不同"的
        // 张量返回相同的缓冲区地址，导致它们相互别名。
        // 一个 tile 的 DMA 加载将静默覆盖另一个 tile 的数据。
        inQueueX.FreeTensor(xLocal);  // 双重释放！损坏空闲列表
    }
    // ...

    unsafe {

            ascend_std::ascend_buf_store_f16(z.wrapping_add(gm_off), buf_z, len);

            // 这里没有 FreeTensor。即使这一行被复制粘贴重复，
            // 也根本没有可以调用的 free 函数。
            offset = offset + tile_size;
        }
        // 内核返回——所有缓冲区隐式释放。
    }
}

核心洞见： 在 C++ 中，FreeTensor() 是一个手动操作，可能被意外重复。在 Rust 中，不存在释放操作——Buffer ID 是类型化的新类型封装（UbBuf、L1Buf 等），在编译期编码存储层级。“双重释放“一个缓冲区 ID 是没有意义的。

6.6 多核偏移量的静默整数溢出

多核内核通过计算 offset = blockIdx * perBlockLen 在 NPU 核心之间分配工作。使用 uint32_t 算术时，此乘法在溢出时静默回绕——例如 8192 * 524288 = 0x100000000 回绕为 0。内核从错误的内存区域读写，可能与另一个 block 的数据产生别名。在 C++ 中，无符号溢出是定义行为（模运算），因此不会产生警告。

C++ — 存在漏洞：

#include "kernel_operator.h"

class KernelVecAddOverflow {
    // ...
    __aicore__ inline void Init(GM_ADDR x, GM_ADDR y, GM_ADDR z, GM_ADDR len_buf) {

        // BUG: 当 blockIdx * perBlockLen > 2^32 时 uint32_t 静默溢出。
        //
        // 示例：8192 个 block，perBlockLen = 524288 (512K 元素)，
        // 总张量大小为 4GB 半精度数据。Block 8192 计算：
        //   offset = 8192 * 524288 = 4294967296 = 0x100000000
        // 但 uint32_t 回绕：offset = 0。此 block 现在与 block 0 的数据别名。
        //
        // C++ 不产生警告——无符号溢出被定义为模运算。
        // 内核静默地读取错误数据。

        }
    }

7.1.1 `ascend_compile` 编译中枢

ascend_compile crate (crates/ascend_compile/) 是一个独立的编译库，将内核编译与 rustc_codegen_mlir 后端解耦。任何 C++ 内核生成器——无论来自 ascend-rs 自身的 MLIR→C++ 流水线、TileLang、Triton、PyPTO（CANN 的 tile 级算子 DSL）还是未来的前端——都可以使用它来编译 AscendC 内核：

7.3 内存安全保障

在整个流程中，ascend-rs 提供了以下编译期安全保障：

安全问题	C++ 方式	ascend-rs 方式
设备内存泄漏	手动 `aclrtFree`	`DeviceBuffer<T>` 的 `Drop` 自动释放
资源释放顺序错误	程序员约定	生命周期系统在编译期阻止
使用已释放的流	无检查	编译错误
发送不安全类型到设备	无检查	`DeviceSend` trait 约束
忘记同步	静默数据错误	类型系统可扩展为强制

8. 性能：从安全到速度

8.1 激活函数基准测试

ascend-rs Rust 内核实现了与手工优化 AscendC C++ 的零开销性能对等。

硬件: Ascend 910B3，CANN 8.5，8 个 AICore 块。

kernel_ops.rs 中所有 16 个激活函数均与等价 C++ 实现进行了基准对比。结果显示，Rust 生成内核在所有测试规模（1K 到 1M 元素）下均实现 0% 性能开销：

激活函数	Rust 耗时 (ms)	C++ 耗时 (ms)	开销
relu_f16	0.042	0.042	0%
sigmoid_f16	0.058	0.058	0%
tanh_f16	0.061	0.062	−1.6%
gelu_f16	0.075	0.075	0%
softmax_1d_f16	0.009	0.015	−40%

softmax 的结果尤为值得关注：Rust 向量内核在相同问题规模下比 C++ 参考实现快 1.6 倍，因为 Rust 实现使用了最优的向量算子链（ReduceMax → Adds → Exp → ReduceSum → Muls），而 C++ 参考实现采用了标量循环。

8.2 Softmax 基准测试——四种实现在昇腾 910B2 上的对比

测试配置

硬件: 昇腾 910B2（Atlas 300T A2 卡），CANN 8.5.0，单 AICore。

参与对比的实现：

实现	语言	代码生成路径	策略
`cpp_naive`	AscendC C++	`ccec`（直接编译）	标量循环，多项式 `exp`
`cpp_opt`	AscendC C++	`ccec`（直接编译）	向量流水线：`ReduceMax` → `Adds` → `Exp` → `ReduceSum` → `Muls`
`rust_vector`	Rust（ascend-rs buffer API）	`rustc` → MLIR → `mlir_to_cpp` → `bisheng`	与 cpp_opt 相同的向量流水线，由 Rust 源码生成
`rust_tile_scalar`	Rust（ascend-rs tile API）	`rustc` → MLIR → `mlir_to_cpp` → `bisheng`	每行 GetValue/SetValue 标量循环；多项式 `exp`

所有内核执行逐行 softmax：对每行计算 exp(x - max(x)) / sum(exp(x - max(x)))。计时使用 AclEvent 在内核启动前后打点；每个形状执行 1 次预热 + 10 次计时迭代，取中位值。

测试结果

一维内核（单行，元素数递增）

元素数	`cpp_naive` (ms)	`cpp_opt` (ms)	`rust_vector` (ms)	`rust_tile_scalar` (ms)	tile / rust_vec
1,024	0.0845	0.0152	0.0085	0.1088	12.8×
4,096	0.3193	0.0152	0.0093	0.4193	45.1×
8,192	—	—	0.0104	0.8303	79.8×

rust_vector 在所有测试规模下均最快。cpp_opt 比 rust_vector 慢 1.6–1.8×；cpp_naive 标量循环比 cpp_opt 慢 10–34×。

Tile API 多行形状

Tile API 在六种形状下测试；参照列为相同元素数的 rust_vector 结果。

形状（行×列）	元素数	`rust_tile_scalar` (ms)	`rust_vector` 等效 (ms)	tile / rust_vec
1×1,024	1,024	0.1088	0.0085	12.8×
4×256	1,024	0.1139	0.0085	13.4×
1×4,096	4,096	0.4193	0.0093	45.1×
16×256	4,096	0.4403	0.0093	47.3×
1×8,192	8,192	0.8303	0.0104	79.8×
16×512	8,192	0.8659	0.0104	83.3×

所有六种 Tile API 形状均通过正确性检查（最大元素误差 < 1.3×10⁻⁸，所有行的和在 1.0±0.01 以内）。

吞吐量

以每秒处理百万元素数表示（越高越好）：

rust_vector  8192 elem:   788 Melem/s  ████████████████████████████████████████
rust_vector  4096 elem:   440 Melem/s  ██████████████████████
rust_vector  1024 elem:   121 Melem/s  ██████
cpp_opt      4096 elem:   270 Melem/s  █████████████
cpp_opt      1024 elem:    67 Melem/s  ███
cpp_naive    4096 elem:    13 Melem/s  █
rust_tile  1x8192 elem:    9.9 Melem/s ▌  （标量回退）
rust_tile  1x4096 elem:    9.8 Melem/s ▌
rust_tile  1x1024 elem:    9.4 Melem/s ▌

rust_vector 吞吐量随元素数超线性增长（从 1K 到 8K 元素，从 121 增至 788 Melem/s），因为更大的 tile 能更好地分摊内核启动开销并充满向量流水线。Tile API 标量回退路径无论形状如何均维持在约 9–10 Melem/s，表明其瓶颈在于标量 S-pipe 吞吐而非内存带宽。

Tile API 标量回退路径为何较慢

当前 tile API softmax 在生成的 C++ 中以纯标量循环实现：

// mlir_to_cpp ascend_tile_softmax_f32 处理程序生成的代码
for (int32_t __r = 0; __r < rows; __r++) {
    int32_t __b = __r * cols;
    float __max = buf0.GetValue(__b);
    for (int32_t __c = 1; __c < cols; __c++) {
        float __tmp = buf0.GetValue(__b + __c);
        if (__tmp > __max) __max = __tmp;
    }
    for (int32_t __c = 0; __c < cols; __c++)
        buf1.SetValue(__b + __c, buf0.GetValue(__b + __c) - __max);
    // ... 逐元素多项式 exp ...
    // ... 标量求和循环 ...
    // ... 标量 Muls 循环 ...
}

GetValue 和 SetValue 在标量 S-pipe 上执行，每次处理一个元素。因此，一个 1024 元素的 softmax 需要约 4,000+ 次标量操作。相比之下，rust_vector 使用 AscendC::ReduceMax、Adds、Exp、ReduceSum 和 Muls——128 路 SIMD 向量指令在 V-pipe 上运行——仅需少量流水线周期即可完成。

为何使用标量？ 910B2 AscendC 编译器/运行时存在一个关于 LocalTensor::operator[](offset) 的隐性缺陷（offset > 0 时），对子视图执行向量操作会产生错误结果。标量回退路径通过直接使用绝对元素索引完全规避了这一问题。在该子视图问题被解决之前——无论通过 AscendC 更新还是不同的缓冲区布局——标量回退是多行 tile 内核正确性的必要选择。

修复路径：PTO 路径（mlir_to_pto → ptoas）完全规避了子视图问题，因为 ptoas 从 PTO-MLIR 的 tile 布局描述自动生成 AscendC，不经过 LocalTensor::operator[] 子视图。

正确性与性能的权衡

实现	正确性	性能类别	瓶颈
`cpp_naive`	✓ 仅一维（不支持多行）	S-pipe 标量	标量 S-pipe
`cpp_opt`	✓ 仅一维	V-pipe 向量	内存带宽
`rust_vector`	✓ 仅一维	V-pipe 向量	内存带宽
`rust_tile_scalar`	✓ 多行（全部 6 种形状）	S-pipe 标量	标量 S-pipe
PTO / `ptoas`	✓（预期，尚未测试）	V-pipe 向量（预期）	内存带宽（预期）

rust_tile_scalar 目前是该基准套件中唯一正确处理多行形状的实现。

8.3 Cube Unit：性能的下一个前沿

Softmax 是仅 V-pipe 的工作负载。 所有操作——ReduceMax、Adds、Exp、ReduceSum、Muls——都在向量单元（V-pipe）上独占执行。昇腾 910B2 拥有第二个专用计算引擎：cube unit（M-pipe），一个拥有独立 L0A、L0B 和 L0C 片上内存层次结构的硬件矩阵乘法器。

这一点至关重要，因为：

Buffer API 和 mlir_to_cpp 不支持 cube unit。 Buffer API 将计算表达为 DMA + 向量操作（仅 TBuf<VECCALC>），无法分配 L0A/L0B/L0C 缓冲区或调用 Mmad()。
PTO 的结构优势专门针对 cube unit 内核。 ptoas 生成的代码使用 Tile<TileType::Left, ...>、Tile<TileType::Right, ...>、Tile<TileType::Acc, ...>——分别位于 L0A、L0B、L0C 的独立内存空间——以及驱动 cube unit 的 TMATMUL() / TMATMUL_BIAS() 指令。这些无法通过向量 buffer API 表达。
对于 softmax 和其他 V-pipe 内核，PTO 相比 buffer API 没有运行时性能优势。 两者最终都降级为相同的 AscendC 向量操作。
对于矩阵乘法（GEMM）、缩放点积注意力和卷积，PTO 是 Rust 达到完整 cube unit 性能的唯一途径。 当前标量回退路径在 5 种测试形状上仅达到约 0.17–0.27 GFlop/s；910B2 的 cube unit 峰值为 32 TFlop/s，需要 PTO 路径——mlir_to_pto.rs 中的实现结构已正确，但等待 CANN 9.x bisheng 对 pto-inst.hpp 的支持。

8.4 矩阵乘法基准测试——标量 vs. Cube Unit

硬件: 昇腾 910B2，CANN 8.5.0。

Cube unit GEMM 吞吐量（aclnnMatmul，f16）

昇腾 910B2 的 cube unit 在矩阵乘法上达到了接近理论峰值的吞吐量。使用 CANN aclnnMatmul 图级 API（内部调度到硬件 cube 引擎），我们测量了从 32×32 到 16384×16384 的 17 种形状：

形状（M×K×N）	中位延迟 (ms)	TFLOPS	状态
256×256×256	0.017	2.0	PASS
512×512×512	0.025	10.6	PASS
1024×1024×1024	0.027	80.4	PASS
2048×2048×2048	0.065	266.4	PASS
4096×4096×4096	0.437	314.5	PASS
8192×8192×8192	3.614	304.2	PASS
16384×16384×16384	27.467	320.2	PASS

矩形/Transformer 典型形状：

形状（M×K×N）	中位延迟 (ms)	TFLOPS	状态
1024×4096×1024	0.067	127.8	PASS
4096×1024×4096	0.132	260.1	PASS
1024×1024×4096	0.037	231.8	PASS
4096×4096×1024	0.122	282.4	PASS
2048×8192×2048	0.245	280.0	PASS

峰值：320 TFLOPS（16384×16384×16384）——达到昇腾 910B2 的 f16 理论峰值（320 TFLOPS）。所有形状均通过正确性检查。

完整结果见 benchmarks/gemm/ascend_910b2_results.csv，基准测试脚本见 benchmarks/gemm/bench_gemm_ascend.py。

标量路径对比

作为对比，当前 mlir_to_cpp 标量回退路径（无 cube unit）的性能：

形状（M×K×N）	Rust 标量 (GFlop/s)	Cube unit (GFlop/s)	差距
32×32×32	0.21	2,000	9,500×
64×64×64	0.24	23,600	98,000×
128×128×128	0.26	236,000	908,000×
256×256×256	0.27	2,010,000	7,400,000×

标量路径完全在 S-pipe 上运行（每周期一个元素），而 cube unit 在 30 个 AICore 上每周期处理 16×16 分形块。

从 Rust 弥合差距

上述 aclnnMatmul 结果使用了 CANN 运行时内置的 matmul 内核。从 Rust 编写的内核达到同等吞吐量的路径：ACLRS_CODEGEN_PATH=pto → mlir_to_pto.rs 发出 cube unit tile 序列（pto.alloc_tile loc=mat/left/right/acc → pto.tmatmul）→ ptoas 编译为带 __ca__/__cb__/__cc__ 限定符的 AscendC → bisheng → NPU 二进制。该路径已实现并通过 ptoas 验证；最后一步等待 pto-inst.hpp 与未来 CANN 版本的兼容性问题解决。

8.5 关键结论

安全不以牺牲性能为代价。 Rust 向量内核在 softmax 上比手写 AscendC C++ 快 1.6–1.8 倍——编译器的类型系统和抽象层不会引入额外开销。
Buffer API 是 V-pipe 工作负载的正确选择。 rust_vector 在 910B2 上的 softmax 测试中达到了理论内存带宽极限。
PTO 是 M-pipe（cube unit）工作负载的正确选择。 GEMM、attention 和卷积需要 cube unit；buffer API 无法触达它。ascend-rs 中的 PTO 路径在结构上已正确实现，等待 CANN 升级即可完成。
多行正确性目前需要标量回退。 Tile API 正确处理了一维 buffer API 无法支持的多行形状，代价是标量性能。一旦 bisheng 支持 pto-inst.hpp，PTO 将恢复向量性能。

9. DeepSeek 推理:跨平台内核基准套件

9.1 为什么选 DeepSeek?

DeepSeek-R1-Distill-Qwen-1.5B 小到能装进 8 GB 统一内存,大到在每一种现实中的加速器上都是 bandwidth-bound,而且架构上代表了现代 transformer 家族:

分组查询注意力(GQA) —— 12 个 Q-head 共享 2 个 KV-head。
SwiGLU MLP —— 每层三个 matmul,可融合为一个内核。
RMSNorm —— 处处替代 LayerNorm。
旋转位置编码(RoPE) —— 原地作用于 Q 和 K。

每个 token 的 decode 在 28 层上读取约 2.6 GB 权重。这让它成为一个带宽基准,而非 FLOPs 基准。硬件上限是 带宽 ÷ 每 token 字节数:

设备	内存带宽	理论 tok/s 上限
Apple M2 Max	400 GB/s	154
Apple M4	120 GB/s	46
Apple M4 Pro	273 GB/s	105
NVIDIA H100 SXM	3,350 GB/s	1,288
NVIDIA RTX 4090	1,008 GB/s	388
NVIDIA Tesla T4	320 GB/s	123
AWS Trainium2	2,800 GB/s	1,077
Google TPU v2-8	600 GB/s	231
Huawei Ascend 910B2	1,228 GB/s	472
Cambricon MLU590	1,228 GB/s	472

任何内核达到这个数字的 60% 就能与手工调优的生产代码竞争;达到 80% 是 memory-bound 内核的目标。同一模型上的 CPU 参考吞吐是 3.7 tok/s —— 这是每条加速器路径都必须跨过的地板。

9.2 13-Kernel 套件

decode 模式下的完整 transformer 层归结为 8 次 dispatch,加上 5 个模型级内核(embedding、两个 RMSNorm 变体、RoPE、argmax)。完整列表,对应 1.5B 模型的 shape(D=1536, NH=12, NKV=2, DH=128, INTER=8960, VOCAB=151936):

#	Kernel	运算	输入 → 输出 shape
1	`rms_norm_1536`	RMSNorm + γ scale	`(1, D)` → `(1, D)`
2	`embedding_lookup`	按行 gather	`(VOCAB, D)`, `(1,)` → `(1, D)`
3	`q_proj_matvec`	matvec + bias	`(1, D)` → `(1, NH·DH)`
4	`kv_proj_matvec`	融合 K + V matvec + bias	`(1, D)` → `(1, NKV·DH)` × 2
5	`rope_q_decode`	Q-head RoPE,原地	`(NH, DH)` → `(NH, DH)`
6	`rope_k_decode`	K-head RoPE,原地	`(NKV, DH)` → `(NKV, DH)`
7	`attention_decode_gqa`	带 KV cache 的 GQA 注意力	`(NH, DH)` + KV cache → `(NH, DH)`
8	`o_proj_residual`	O-projection + residual add	`(1, NH·DH)` → `(1, D)`
9	`mlp_gate_up_silu`	融合 gate + up + silu·mul	`(1, D)` → `(1, INTER)`
10	`down_proj_residual`	down-projection + residual add	`(1, INTER)` → `(1, D)`
11	`silu_mul_fused`	独立 SwiGLU	`(1, INTER)` × 2 → `(1, INTER)`
12	`residual_add`	逐元素加	`(1, D)` × 2 → `(1, D)`
13	`argmax_greedy`	在 logits 上取 argmax	`(1, VOCAB)` → `(1, 1)` u32

完整 Rust 源码在 crates/deepseek_metal/src/tile_kernels.rs,用的是安全的 tile.rs view API:

#[ascend_std::aiv_kernel]
pub unsafe fn rms_norm_1536(input: *const f32, gamma: *const f32, output: *mut f32) {
    let ctx = unsafe { GmDeviceCtx::new() };
    let in_v   = unsafe { ctx.view::<1, D, f32>(input) };
    let g_v    = unsafe { ctx.view::<1, D, f32>(gamma) };
    let out_v  = unsafe { ctx.view_mut::<1, D, f32>(output) };

    let x      = tile_load_view_f32(&in_v);
    let g      = tile_load_view_f32(&g_v);
    let normed = safe::tile_rms_norm_f32::<1, D>(x, 1e-6);
    let out    = safe::tile_mul_f32::<1, D>(normed, g);
    tile_store_view_f32(&out_v, out);
}

同一份源码编译到每一个 mlir_to_<target> 后端。各目标的参考内核签入在 benchmarks/deepseek_tile_kernels/templates/<target>/ 下。

9.3 Ascend 910B2 —— 头条结果

硬件:Huawei Ascend 910B2,CANN 8.5.0,bisheng 编译器,联合 mlir_to_cpp + mlir_to_pto codegen 路径。

设置:28 层 DeepSeek-R1-Distill-Qwen-1.5B,f16 权重,每次 forward pass 单条 ACL stream。decode 路径用 cpp-tile 内核跑 RMSNorm / RoPE / SiLU,用 PTO cube matmul 跑每层的 f16 projection,用 cached-executor 的 aclnnIncreFlashAttention 跑 attention。

实现	Decode tok/s	加速
CPU 参考(float)	3.7	1.00×
aclnn-only 基线	68.3	18.5×
ascend-rs(联合 `mlir_to_cpp` + `mlir_to_pto`)	168.9	45.6×(对 aclnn 2.47×)

168.9 是怎么到的

910B2 上的优化序列,每一步都对前一步测量:

步骤	tok/s	Δ
aclnn-only 基线(`aclnnMatmul` 做 f16 matmul)	68.3	—
所有每层 Q/K/V/O/gate/up/down projection 改走 f16 PTO matmul	114.5	+46.2
lm_head 在 PTO 上走 host-side B-repack	149.4	+34.9
融合 kv-proj 和 gate-up 的权重(每对一个 matmul)	151.6	+2.2
自制 cpp-tile `residual_add_rms_norm`(4.4 µs vs aclnn 融合版 27 µs)	157.5	+5.9
Cached-executor `aclnnIncreFlashAttention`(38 µs vs 普通版 61 µs)	168.0	+10.5
杂项:lm_head chunk sweep、QKV 融合、走 vec matvec 的 `attention_1head_cpp`	168.9	+0.9

贡献最大的两个自制内核(residual_add_rms_norm cpp-tile 融合版,以及 f16 PTO matmul 的 blocking)都由 rustc_codegen_mlir 从普通 Rust tile-API 源码生成 —— 没有手写 AscendC。逐算子计时见附录 I。

同一份二进制在 910C 上

同一份构建产物在 Ascend 910C(cube-only)上重新构建,ptoas 的 --cce-fatobj-link 路径负责 matmul 侧。在 910C 上的切分是 每层时间的 98.4% 在 NPU、1.6% 在 CPU —— 仍留在 host 的唯一内核是 RMSNorm,因为 910C 的 cube 单元对它没有加速(它是 memory-bound,DMA 拷贝占主导)。910C 的端到端 tok/s 暂不报告,等待 28 层在稳定的 910C 芯片分配上做更长的正确性验证。

9.4 Google TPU v2-8(Colab)—— 162.9 tok/s

硬件:Google Colab v2-8(Cloud TPU,8 核 × 8 MiB MXU,600 GB/s HBM),mlir_to_tpu codegen 发射 JAX Pallas。

设置:rms_norm 和 rope_inplace 走生成的 Pallas kernel;GQA attention 走生成的 Pallas;matvec 按内存层级切分 —— Pallas 跑 q/k/v/o projection(shape 小,VMEM 友好),XLA jnp.dot 跑 gate/up/down/lm_head(shape 大,受益于 XLA 的 HBM staging)。

实现	Decode tok/s	与 HF 一致性
ascend-rs(Rust → Pallas)	162.9	16/16 greedy
原生 JAX 基线(同 shape)	≈ 166	16/16

在所有逐 op 对照测量上取平均,生成的 Pallas kernel 达到原生 JAX 基线的 0.98×。端到端做了 greedy-token 一致性验证:16 个生成 token 全部逐字节匹配 HuggingFace 参考实现。TPU 结果是整个套件里最重要的跨厂商交叉验证:它表明一个完全没有 C++ 出口的后端(Pallas 从 Python DSL 直接进 XLA)能从同一份 Rust 源码(这份源码本来是给 AscendC 写的)产出有竞争力的结果。

9.5 Apple M2 Max —— 91.7 tok/s(打败手工调优的 MLX)

硬件:Apple M2 Max,12 核 CPU,38 核 GPU,400 GB/s 统一内存带宽,macOS 14.5,Metal 3.1。

设置:28 层 DeepSeek-R1-Distill-Qwen-1.5B,bf16 权重直接以 Metal bfloat 上传到 GPU。每次 forward pass 单个 Metal command buffer。Repetition penalty 1.3,temperature 0.0(greedy)。

实现	Decode tok/s	占峰值(154)的百分比
ascend-rs(Rust → MSL)	91.7	60%
MLX 0.29.1(Apple,手工调优)	≈ 88	57%

经过 rustc_codegen_mlir → mlir_to_msl 后,从 Rust 源码生成的内核在 decode 上超过了 Apple 手工调优的 MLX。在典型的推理会话里(一个 prompt,几百个生成 token),decode 是主导成本,所以这个数字对终端用户延迟最关键。

Apple M4(4P+6E CPU,10 核 GPU,120 GB/s):decode 33–35 tok/s vs MLX 32 tok/s —— Metal codegen 路径在这个更小的部分上也打败 MLX,但 prefill(9.3 vs MLX 72)还卡在重写 prefill matmul 使用 simdgroup_matrix_multiply。

91.7 是怎么到的

M2 Max 上的优化轮次(每步对前一步):

步骤	tok/s	Δ
基线(模板签入版)	90.3	—
`attention_decode_v4`(TG-mem Q 缓存 + float4)	91.3	+1.0
把 token buffer 从内循环外提	91.7	+0.4
最终	91.7	+1.4

两个尝试的优化经过测量被回滚,因为会倒退:

尝试	tok/s	Δ
`matvec_f16_cached`(手动 A-cache)	85.1	−5.2(回滚)
融合 RMSNorm + 下一个 matvec	78.7	−13(回滚)

Apple GPU 的 L1/L2 已经缓存了复用的激活,所以手动 threadgroup 缓存只有在(a)数据不在 cache 且(b)每线程计算大到能摊销 barrier 开销时才有用。对 K=1536(6 KB)的 decode matvec 来说两条都不成立。

9.6 NVIDIA Tesla T4(Colab)—— 53.7 tok/s

硬件:Google Colab 上的 NVIDIA Tesla T4,320 GB/s HBM2,CUDA 12.1,mlir_to_gpu codegen 发射 CUDA C,用 nvcc -arch=sm_75 -O3 编译。

设置:生成的 rms_norm_1536、matvec_f16(带 _bias 和 _add 变体覆盖融合情况)以及 GQA attention_decode_gqa 驱动 decode loop;权重加载和 tokenization 用 host 侧 Python 粘合。

实现	Decode tok/s
ascend-rs(Rust → CUDA)	53.7
320 GB/s 下的理论峰值	123

53.7 tok/s 是 T4 理论带宽上限的 44%。剩下的 gap 分两块:次优的 matvec tiling(mlir_to_gpu 路径当前是每线程一个元素,没有走 warp-striped)和 matmul_f32 仍然临时走 cuBLAS。两件事都记录在第 13 章 §12.3.1 作为短期的 mlir_to_gpu + cudarc 集成工作。

每 token 内核的对齐情况同 Ascend 结果一致:13 个内核全部编译通过;发射的 .cu 源码是 2,001 行,由同一份 13-kernel tile_kernels.rs 生成。

9.7 AWS Trainium(`trn1.2xlarge`)—— 12.2 tok/s

Trainium 是这份清单中唯一一个单 kernel eager dispatch 确实不可行的后端:@nki.jit 首次调用任一 kernel 要付出约 10 s 的 graph-build + 硬件加载开销,而且没有跨调用缓存。DeepSeek-R1 的 28 层每个 decoded token 要分发 370+ 次 kernel 调用,如果走 eager,每 token 将耗时数十小时。正确的解法不是改 codegen,而是改外层 wrapper:把发射出的 NKI kernel 烘焙进一个被 Neuron 一次性编译为 Neuron Executable File Format(.neff)的 traced PyTorch-Neuron 图里。

实现	Decode tok/s	Trace 编译耗时	64-token 墙钟
`mlir_to_nki`(eager `@nki.jit`)	~0.001	无	> 1 h
`mlir_to_nki` + `torch_neuronx.trace`(单个 NEFF)	2.5	70.9 s	25.56 s
`mlir_to_nki` + `torch_neuronx.trace`(halves)	12.2	460.5 s	5.23 s

“halves” 指把 28 层栈拆成两个 14 层的 torch_neuronx.trace NEFF,加一个独立的 lm_head trace;Neuron 的 layout optimiser 能分别处理每一半而不至于 HBM 溢出,每 token 的执行依次打完三个 NEFF,中间没有 kernel 分发开销。编译代价是一次性的 461 s AOT;一旦缓存,每 64 token decode 墙钟 5.23 s。

驱动 decode 的六个发射 NKI 内核:rms_norm_1536、matvec_f16、matvec_f16_bias、matvec_f16_add、gate_up_silu、GQA attention。全部来自同一份 13-kernel tile_kernels.rs 源码;发射的 .py NKI 代码 1,872 行。

12.2 tok/s 是 Neuron Core 在 DeepSeek-R1-Distill-Qwen-1.5B bf16 下 128 GB/s 带宽上限的 9.5% —— 比 M2 Max 或 T4 比例低,是因为 Neuron 的 bf16 权重路径强制走 f32 累加器,把带宽受限的 matvec 的有效 HBM 带宽砍了一半。填平差距需要 Neuron 专用的 f16 累加器路径,或者把 matvec 后的 cast 融合进下一个 kernel;两件事都记录在第 13 章。

构件:nki_ascendrs_deepseek.csv 记录了包括单 NEFF 与 halves 两种变体在内的完整运行结果。

9.8 时间去哪了 —— 逐内核分解(M2 Max)

M2 Max 上一个 decoded token(28 层 × 8 dispatch + 5 个模型级 dispatch = 229 次 kernel launch):

内核类别	每 token 时间 (ms)	占 decode 比例
Q/K/V/O matvec	4.3	39%
Gate + up + silu (MLP)	3.1	28%
Down-projection	2.1	19%
Attention (decode v4)	0.8	7%
RMSNorm × 2/layer	0.4	4%
RoPE Q + K	0.2	2%
Vocab argmax	0.1	1%
合计	11.0	100%

七个 matvec/MLP 内核 —— 来自 §9.2 套件的第 3、4、8、9、10 项 —— 占 decode 时间的 86%。优化精力花在这些内核上回报最大,这也是为什么 §9.5 列出的每一项优化都瞄准 matvec / attention 路径。Norm 和 RoPE 合起来每 token 不到 1 ms;把它们融合掉(我们试过)省不出可测量的带宽,还要加计算。

9.9 跨厂商状态

这份 13-kernel Rust 源码是每个 mlir_to_<target> 后端的共同输入。当前已测得的端到端状态(数字来自配套论文 Table 2):

后端	目标	行数	Decode tok/s
`mlir_to_cpp` + `mlir_to_pto`	Ascend 910B2(联合)	11,383 + 4,955	168.9
`mlir_to_tpu`	Google TPU v2-8(Pallas)	1,645	162.9
`mlir_to_msl`	Apple M2 Max(Metal)	1,730	91.7
`mlir_to_gpu`	NVIDIA T4(CUDA)	2,001	53.7
`mlir_to_nki`	AWS Trainium(`trn1.2xlarge`)	1,872	12.2
`mlir_to_spirv`	Vulkan(任意 GPU)	1,571	见下面注

NKI(AWS Trainium)。六个发射的内核(rms_norm_1536、matvec_f16 / _bias / _add、gate_up_silu、GQA attention)都编译并运行通过,端到端在 trn1.2xlarge 上以 12.2 tok/s 跑完整 DeepSeek-R1-Distill-Qwen-1.5B decode。Eager @nki.jit dispatch 每次调用要付出约 10 s 建立开销且没有跨调用缓存(每 token 370+ 次 dispatch 让 per-kernel eager 不可行),因此发射的 kernel 被烘焙进两个 14 层的 torch_neuronx.trace NEFF 以及一个单独的 lm_head trace。traced 路径把编译和权重传输成本都摊平:461 s 一次性 AOT 编译 → 64 token decode 5.23 s。详见 nki_ascendrs_deepseek.csv。

Vulkan(SPIR-V)。端到端 decode 需要一个暴露 shader-f16 特性的 adapter。我们能用到的、既支持 SPIR-V 又能跑 Colab notebook 的硬件只有 T4,而 Colab 的 T4 在 Vulkan 下只暴露 Mesa llvmpipe(CPU 光栅器)—— 这会让 decode loop 超时。Apple M2 Max 上经 Vulkan 后端跑的 per-kernel softmax 达到 90× CPU 加速(见附录 I)。

对代码树里其余的后端(mlir_to_musa、mlir_to_aie、mlir_to_bang、mlir_to_gaudi、mlir_to_csl、mlir_to_hexagon、mlir_to_linalg),13-kernel 套件都能干净编译;on-device decode 测量仅卡在各个 rig 的硬件时间分配。

9.11 为什么是套件,而不是单一内核

单内核基准(独立 softmax、GEMM、RMSNorm)对诊断某个具体瓶颈有用,但它们系统性地高估那些无法组合的优化的价值:

缓存激活在单独 matvec 基准里是明显赢,放到 transformer 层内部就明显输 —— 上一个 matvec 已经把 cache 暖了起来(§9.5)。
把 RMSNorm 融合进下一个 matvec 在融合内核微基准上赢,放到真实层里就输 —— 同一份 norm 输出被 Q、K、V 三个 matmul 消费。
一个忽略 KV cache 的“快 attention“内核毫无意义;decode 里,KV cache 就是 attention 的输入。

一个绑定到真实模型的 13-kernel 套件是能捕捉这些错误的最小基准。它也让厂商能诚实地对比后端:§9.9 里每个后端看到同一份 Rust 源码、同一批 shape、同一个内存流量预算。

9.12 关键要点

一份 Rust 源码,四种生产加速器上端到端测量完成。Ascend 910B2 168.9 tok/s,Google TPU v2-8 162.9,Apple M2 Max 91.7,NVIDIA T4 53.7 —— 全部来自同一份 13-kernel tile_kernels.rs,经过不同的 mlir_to_<target> 后端编译。后端规模从 1,571 行(SPIR-V)到 11,383 行(mlir_to_cpp)不等,所以瞄准一个新厂商是一项有边界的工程,不是研究项目。
910B2 上对 CPU 参考 45.6×,对 aclnn-only 基线 2.47×。Ascend 路径证明了一个安全优先的 Rust 内核工具链不会牺牲性能:头条数字来自编译器生成的内核流水线,而不是手写 AscendC。
Metal codegen 路径在 decode 上打败手工调优的 MLX。M2 Max 上 91.7 vs ≈ 88,M4 上 33–35 vs 32。Apple 的工程师是针对 Apple 自己的硬件手工调的 MLX;ascend-rs 从为另一家厂商写的 Rust 源码里产出了有竞争力的结果。
TPU Pallas 交叉验证达到原生 JAX 的 0.98×,与 HF 16/16 greedy-token 对齐。最干净的证据,表明 Rust → MLIR → Pallas 路径产出的内核是正确的,而不只是数值上近似。
微基准在整流水线性能上撒谎。两个在孤立测量里显示为赢的优化(缓存、融合)在 M2 Max 的完整 decode 路径上倒退了 5–13 tok/s。套件级测量是唯一能抓到这种情况的办法。

10. 用 Rust 安全卫士捕获 ptoas 的盲区

10.1 为什么 ptoas 需要外部卫士

ptoas 是一个分阶段 lowering 的编译器:输入 PTO-MLIR(tile dialect),输出 bisheng 可消费的 AscendC C++。内部流水线里最关键的一个 pass 是 PlanMemoryPass——在此点,每一个抽象的 pto.alloc_tile 都被具体化为 (address_space, offset, rows, cols, dtype, blayout, slayout) 记录。这之后,IR 仍然是 MLIR,ptoas --print-after-all 可以把它 dump 出来,但 ptoas 本身并不会再去校验以下几项——这些不变量,只要手里有 post-pass 后的 plan,就能轻而易举地验证。

它默默跳过的六条不变量:

#	不变量	违反时的故障模式
1	两个活跃、形状不同的 tile 不得在同一地址空间中占用重叠字节	运行期静默覆盖;kernel 输出错误数据
2	每个地址空间的高水位字节使用量不得超过设备容量(`DeviceSpec`)	SRAM 溢出;kernel 崩溃或损坏邻近 tile
3	`pto.tmatmul` 操作数必须位于正确的 L0 子空间(lhs∈Left、rhs∈Right、acc∈Acc)且 dtype 三元组在立方单元接受集合内	描述符垃圾数据;在某些 CANN 版本下数值错误
4	ptoas 描述符上限:OUTER < 2²⁴,ROW < 2¹⁶	描述符被截断;N 维错误
5	分配的 tile 都应该被使用	浪费 UB 预算——不是 bug,但是 ptoas 从不提及的“正确性气味“
6	tile 线性使用:写之后,下一次写之前应至少有一次读(通告性,flatten 循环)	死写;上一次的值丢失

本章的其余部分,构建能够强制执行全部六项、最小化的工具,并用真实违例来证明它的价值。

10.2 设计:三步、三件 artifact

该卫士围绕一个刻意简单的流水线设计。每一步产出一件 artifact,供下一步消费;每件 artifact 都是纯文本,人可以在任意中间态读取。

  [第 1 步]               [第 2 步]                      [第 3 步]
┌──────────────┐   .pto   ┌──────────────┐   plan.rs   ┌───────────────┐   报告     ┌────────────────┐
│  ptoas       │ ───────▶ │ pto_to_rust::│ ──────────▶ │ pto_to_rust:: │ ─────────▶ │ pto-diff CLI   │
│ --print-...  │          │ parse_stage2 │             │   check_all   │            │ (人类可读输出)  │
└──────────────┘          └──────────────┘             └───────────────┘            └────────────────┘
 PlanMemoryPass            类型化 Rust                 SafetyReport                  error/warn 行
 之后的 MLIR               `Plan { funcs }`            { violations }               file:line:kind:msg

Dump stage-2 PTO-MLIR。运行 ptoas --print-after-all <file.acl.pto>,保留 IR Dump After PlanMemoryPass 之后的最后一个 module。此 IR 对每一个 tile 都带有具体的 (offset, size) 注释——正是卫士所需要的。
解析为带类型的 Rust。pto_to_rust::parse_stage2(&str) -> Plan 把 MLIR 文本转成 Plan { arch, funcs: Vec<PlanFunc> },其中每个 PlanFunc 有 BTreeMap<Ssa, TileSlotX> 记录具体 tile slot,以及引用它们的 Vec<PlanOp>。自此,Rust 的类型系统接管;解析器一旦接受,后续所有推理都在静态类型值上进行。
跑 check_all 并把违规映射回 .acl.pto。SafetyReport::check_all(&plan, &device_spec) 跑完上面六项检查,产出 SafetyReport { violations: Vec<SafetyViolation> }。pto-diff CLI 拿到原始 .acl.pto 路径,前置到每条违规消息前,输出形如 file: severity: [kind] func: message 的行——可 diff、可 grep,看起来就是一条编译器诊断。

关键设计决策在第 1 步:与其用 Rust 重写 PlanMemoryPass(数月工程,永远跟 ptoas 对不齐),卫士信任 ptoas 的放置结果,只校验放置结果上必然成立的不变量。这让 pto_to_rust 保持在 600 行 Rust 以内,同时对真实 bug 足够锋利。

10.3 以 `smoke_tstore_fp_v1.acl.pto` 走一遍三步流程

10.3.1 Kernel 背景

smoke_tstore_fp_v1.acl.pto 是一个 47 行的手写 kernel:把 [M,N] 的 f32 累加器经过一个 pto.tstore_fp(融合反量化存回)下沉到 GM,同时使用一个 f16 的 scaling tile 用于 per-channel scale。它被 ptoas 接受并返回 rc=0——但在实际 910B2 上,生成的 kernel 会:(a) 静默越过 scaling 空间容量上限,(b) 让 scaling tile 使用非默认的 RowMajor 布局,该布局在 fb-dequant 路径上未被支持。两个问题都在原始 .acl.pto 上无法静态识别,但都能从 post-PlanMemoryPass 的 plan 上精确识别。

10.3.2 手动跑三步

$ /usr/local/bin/ptoas-bin/ptoas \
    --print-after-all /tmp/smoke_tstore_fp_v1.acl.pto \
    -o /tmp/out.cpp 2> /tmp/stage2.dump
$ echo "ptoas rc=$?"
ptoas rc=0

# 抽出最后一块 "IR Dump After PlanMemoryPass"
$ awk '/IR Dump After PlanMemoryPass/{flag=1; next} flag' /tmp/stage2.dump > /tmp/stage2.mlir
$ wc -l /tmp/stage2.mlir
74 /tmp/stage2.mlir

# 第 2 步 —— 解析为带类型的 Rust(通过 pto-diff 调用库)
# 第 3 步 —— 跑检查并输出诊断
$ ./target/release/pto-diff /tmp/stage2.mlir
/tmp/stage2.mlir: error: [capacity] m: scaling high-water 4352 B exceeds capacity 4096 B (on Ascend910B2 (CANN 8.5))
/tmp/stage2.mlir: warn: [op-constraint] m: pto.tstore_fp: scaling tile `%11` has slayout RowMajor, typical is none_box
/tmp/stage2.mlir: 1 error(s), 1 warning(s)

两条诊断,都是真实的。error 直接决定 kernel 的正确性(SRAM 溢出);warning 决定它的可用性(fb-dequant 被静默丢弃)。两条诊断在 ptoas 的输出中都没有。

10.3.3 用一条命令跑完三步

为方便起见,pto-diff 提供 --from-pto,一键跑完:

$ ./target/release/pto-diff --from-pto /tmp/smoke_tstore_fp_v1.acl.pto
/tmp/smoke_tstore_fp_v1.acl.pto: error: [capacity] m: scaling high-water 4352 B exceeds capacity 4096 B (on Ascend910B2 (CANN 8.5))
/tmp/smoke_tstore_fp_v1.acl.pto: warn: [op-constraint] m: pto.tstore_fp: scaling tile `%11` has slayout RowMajor, typical is none_box
/tmp/smoke_tstore_fp_v1.acl.pto: 1 error(s), 1 warning(s)

每一行开头的文件路径是原始 .acl.pto,而不是中间 dump——IDE 或 git diff 视图能直接跳到正确位置。这就是映射回原文件这一步:虽然检查跑在 post-PlanMemoryPass 的 Plan 上,但诊断可以重新贴标到任何上游 artifact。

10.3.4 每个诊断字段的含义

/tmp/smoke_tstore_fp_v1.acl.pto: error: [capacity] m: scaling high-water 4352 B exceeds capacity 4096 B (on Ascend910B2 (CANN 8.5))
├──────────────── 定位 ──────────┤  │     │             │
                                    │     │             └── module 中的函数名
                                    │     └─── SafetyKind 标签(aliasing/capacity/op-constraint/
                                    │         matmul-bounds/dead-tile/linear-use)
                                    └── 严重性(error=kernel 错;warn=疑似 bug,通告性)

消息中的 DeviceSpec(Ascend910B2 (CANN 8.5))是本次检查使用的容量表。用 pto-diff --device spec.toml 可以传入自定义规格以针对其他 SoC 版本。

10.3.5 ptoas 0.26 与 ptoas 0.29 标志的差异

上文示例使用的是 ptoas 0.26 的标志,每个 pass 的 IR 都内联 dump 到 stderr。ptoas 0.29(随后续 CANN 8.5 补丁以及 CANN 9.x 发布)重命名了这些标志,并将 dump 重定向到文件系统:

ptoas 0.26(stderr)	ptoas 0.29(树状目录)
`--print-after-all`	`--mlir-print-ir-after-all`
`--print-module-scope`	`--mlir-print-ir-tree-dir=<dir>`
在 stderr 中作为 `IR Dump After PlanMemoryPass` 块输出	每个 pass 一个文件,位于 `<dir>/builtin_module_*/N_<pass-name>.mlir`;plan-memory dump 是 `3_pto-plan-memory.mlir`

pto-diff --from-pto 对两个版本透明兼容。它先尝试 0.29 的 tree-dir 路径——建立按 PID 命名的临时目录,用新标志调用 ptoas,读取 3_pto-plan-memory.mlir,然后清理;若该路径未产出任何 dump,则回退到 0.26 风格的 stderr 抓取。无论 PATH 上是哪个 ptoas,用户得到的诊断输出一致。(若两条路径都失败,pto-diff 会同时报告两条错误信息,方便用户判断是哪一套兼容假设失效了。)

10.4 第二个 kernel:aliasing 与 dead tile

同一套三步流程,作用于 smoke_tdequant_v3.acl.pto,会浮现两种不同的违规——说明卫士的能力具有一般性。

$ ./target/release/pto-diff --from-pto /tmp/smoke_tdequant_v3.acl.pto
/tmp/smoke_tdequant_v3.acl.pto: error: [aliasing] m: slots %7 and %5 overlap in vec at [1024, 5120) and [4096, 4352)
/tmp/smoke_tdequant_v3.acl.pto: warn: [dead-tile] m: slot `%3` allocated in vec at offset 8192 but never used
/tmp/smoke_tdequant_v3.acl.pto: 1 error(s), 1 warning(s)

Aliasing(error)。%5 是 16×64 i8 tile,放置于 UB offset 4096,长度 1024 B。%7 是 16×64 f32 tile,放置于 UB offset 1024,长度 4096 B。它们的字节区间 [4096,4352) 与 [1024,5120) 在 [4096, 4352) 重叠——f32 tile 的 256 字节就是 i8 tile。PlanMemoryPass 因为 liveness 分析认定二者不共存而故意复用了这块区域,但二者形状不同,卫士因此把这次复用从“故意“降级为“可能是 bug“。在本例中确实是 bug:在 op 调度中二者同时活跃。
Dead tile(warning)。%3 被分配,但从未被任何 op 读取或写入——浪费了 4 KiB 的 UB 预算。ptoas 既不回收也不警告。

两个 kernel 都能通过 ptoas 产出可运行的 .cpp。两个都会在硬件上静默出错。卫士在编译期把故障显形,早于 ccec、bisheng,也早于漫长的 NPU 上“改—编—跑“循环。

10.5 把卫士的违规映射回 ptoas

因为卫士跑在 ptoas 自身的输出(stage-2 MLIR)上,它找到的每一条违规,都是某个上游 patch 的具体候选项:

卫士检查	如何折叠回 ptoas
`[aliasing]`	新增一个 `VerifyAfterPlanMemoryPass`——按地址空间把 slots 按 offset 排序后 pair 扫描。卫士在 `check_aliasing` 中的 sort-and-scan 实现(每个空间 `O(n log n)`,实践中 `n < 64`)几乎可以原样移植。
`[capacity]`	已在 `PlanMemoryPass` 自身可知——它就是该 pass 计算出来的数值。pass 末尾加一行 `assert(high_water <= cap)` 就能把运行期崩溃变成编译期报错。
`[op-constraint]` lhs/rhs/acc	`pto.tmatmul` / `pto.tmatmul.acc` / `pto.tstore_fp` 上的 op verifier。ptoas 已有 op verifier 基础设施;每项大约 10 行。
`[matmul-bounds]`	跑在 plan 上的 stage-2 verifier。描述符上限知识(OUTER<2²⁴、ROW<2¹⁶)已存在于 lowering,把它暴露给 verifier 只是一次重构,不是新分析。
`[dead-tile]`	廉价的 post-pass:对每个 slot,检查其 SSA 是否出现在任何 op 的 `reads() ∪ writes()`。只发 warning;并非每个 dead tile 都是 bug。
`[linear-use]`	通告性启发式;要晋升为硬规则,需要作用域感知分析(当前 `scf.for` 会被 flatten)。

把前四项折叠进 ptoas,会让卫士在那些检查上变得冗余——而这正是目的。卫士之所以存在,是为了示范:哪些不变量可以在不重写 ptoas 的前提下达成编译期保证;并在上游支持到位之前,给用户一个兜底。

10.6 端到端复现脚本

仓库里的 blog/mdbook/scripts/ch11_safety_demo.sh 一键跑完整套演示,非交互式:它构建 pto-diff、把两个 smoke .acl.pto 放进 /tmp、在每个上面跑卫士,并原样打印预期诊断。

$ bash blog/mdbook/scripts/ch11_safety_demo.sh
== Tool versions ==
ptoas 0.26
pto_to_rust 0.1.0  (tag pto_checks, commit f41b29b1)
rustc 1.91.0-nightly

== Demo 1: smoke_tstore_fp_v1 ==
ptoas rc=0

  warn:  [op-constraint] m: pto.tstore_fp: scaling tile `%11` has slayout RowMajor, typical is none_box

== Demo 2: smoke_tdequant_v3 ==

oracle findings:
  error: [aliasing] m: slots %7 and %5 overlap in vec at [1024, 5120) and [4096, 4352)
  warn:  [dead-tile] m: slot `%3` allocated in vec at offset 8192 but never used

== Summary ==
ptoas accepted both files with rc=0.
Oracle found 2 errors + 2 warnings across the two files.

脚本只读(除 /tmp 之外不写任何文件),只要 ptoas 在 PATH 上,卫士二进制已构建在 target/release/pto-diff,就能跑。在 910B2 测试机上整个 demo 两秒内跑完。

10.6.1 在 910B2 / CANN 8.5 / ptoas 0.29 上的实时录制

配套的两个脚本 blog/mdbook/scripts/ch11_bad_demo.sh(跑在 910c 主机上)与 blog/mdbook/scripts/ch11_bad_demo_remote.sh(工作站上的 ssh 包装)对比一个干净的 softmax 与 ch11_make_bad_softmax.py 生成的坏版本。坏版本注入了 48 个“已 tload 但永不读取“的 VEC tile;ptoas 0.29 依然返回 rc=0,但其 PlanMemoryPass 将 48 个 tile 全部堆在偏移 4096 处——覆盖了在用的工作 slot %3 与 %11。卫士报出 96 条 aliasing 错误。以下为对 910B2 测试机上真实的 /usr/local/bin/ptoas-bin/ptoas 0.29 实时录制的结果:

ch11 坏 softmax demo — ptoas rc=0 vs 卫士 96 errors

重点在于同一个编译器下的对比:ptoas 对两个文件都接受,卫士对两个文件都运行,只有卫士能区分出那个会破坏内存的版本。

10.7 局限与非目标

卫士信任 ptoas 的放置结果。 若 PlanMemoryPass 给出错误偏移(ptoas 的 bug),卫士要么漏掉违规,要么报出错误字节区间。目标不是去二次审核 ptoas 的分配器,而是用一组独立的不变量校验其输出。
循环被 flatten。 check_linear_use 会折叠 scf.for 主体——每次迭代合法地重写同一个 tile,可能被误报成 WAW。正因如此,该检查是 Severity::Warning,不是 Error。作用域感知的 liveness 分析可以解除该限制,但 pass 会更复杂。
DeviceSpec 按 SoC 分。 内置规格是 Ascend910B2 (CANN 8.5)。其他 SoC 版本(Ascend 910_9392、310P3、即将发布的 910C)有不同的容量与 dtype 规则;它们可表为 TOML 文件,通过 --device 传入。

10.8 本章在大图景中的位置

卫士是一个小工具——600 多行 Rust,两个 smoke kernel,一个 bash 脚本——但它体现了本书反复出现的一个主题:把 Rust 的类型系统引入加速器工具链,能把隐藏的正确性故障转化为编译期错误。第 4 章在 kernel 源码层面做过一次;第 6 章为整个 MKB 语料做过一次;这一章表明同样的思路适用于厂商 PTO 编译器的中间 IR。鉴于 ptoas 在 910B2 的 M 流水线立方路径上是关键一环,即便只在两个手写 smoke 上早早抓到 4 个真实 bug,其价值也足以抵消 600 行代码的成本。

10.9 端到端:在 910B2 上观察坏 kernel 触发硬件异常

§10.6 展示了卫士在编译期抓出 aliasing。本节在真实 NPU 上把闭环跑完——把两个 fixture 都送上 910B2,观察 ptoas 隐藏的运行时后果。crate 位于 examples/ch11_exploit/:build.rs 用 ptoas → ccec 编译两个 .acl.pto(ch11_sm_good.acl.pto、ch11_sm_bad.acl.pto),main.rs 用同一份确定性输入分别在 910B2 上启动它们,与 CPU 参考的 softmax 比对。

为什么用两个子进程

落地 demo 时碰到一个微妙的运行时现象:在同一进程内先后注册两个 PTO 设备 binary,第二次 launch 会让 910B2 的 vector core 直接异常退出(Error: Vector core execution exception),哪怕这两个 binary 各自都没问题。错并不在我们的二进制——把 good 替换成已经独立验证通过的 examples/tile_softmax 输出,问题照样复现。这是两次背靠背 rt_dev_binary_register 调用之间的相互作用,我们尚未刨到根因。

所以 demo 选择 fork:父进程用 --variant good 与 --variant bad 各启动自己一次,每个子进程跑完一次 Acl::new() → KernelLoader::from_bin_path → kernel.launch 后只打印一行 RESULT,父进程再把表格拼出来。这同时也是未来 CI 检查的合理形态——一个进程跑一个 kernel,把 RESULT 行与 golden transcript 对 diff。

实际观察到的 transcript

$ ASCEND_DEVICE_ID=1 cargo run --release -p ch11_exploit
=== ch11_exploit: 1×1024 f32 softmax on 910B2 ===
  variant   max_abs_err  max_rel_err        sum    nan verdict
  good          2.33e-9      7.20e-7   1.000000      0 PASS
  bad               NaN          NaN        NaN      0 CRASH: Vector core execution exception.

Compile-time: pto-diff flagged `bad` with aliasing/capacity warnings
              (see §10.6 in blog/mdbook/src/ch11-safety-oracle.md).
Runtime:      `bad` produced wrong output / crashed — the oracle was right.

good 行就是任何一个写得好的 softmax 应有的样子:max_abs_err 距 CPU 参考差一个 ULP,行求和精确为 1.000000——数值意义上正确。

bad 行是昂贵的回答。同一份 kernel 主体多挂了 48 个无人读取的 dead tload tile,并没有安静地算出错误数字——它把 vector core 直接打挂,运行时返回 “Vector core execution exception”,任何输出都没写回 host 内存。原因:ptoas 的 PlanMemoryPass 把这些 dead tile 安置在与活跃 tile 重叠的偏移上,运行时硬件试图把 MTE2 load 写进 V-pipe 正在读取的同一批 UB slot——立刻在 aicore 上触发未初始化张量异常,而不是悄悄地算错。

这其实比 §10.6 预测的“数值悄悄出错“信号更强——bug 严重到甚至阻止了静默错误。但这并不让人安心。它意味着:在“ptoas 说 OK“和“你的 kernel 一launch 就挂“之间,卫士的编译期标记是唯一的信号;若坏 fixture 落到了硬件容忍度更高的位置(例如 MTE3 store 与一份已用完的 V-pipe 临时量重叠),我们看到的就会是 max_abs_err = 1.7e-2、sum = 0.84,无任何故障——任何理智的测试用例都会判定“数值噪声,放行“。

无论哪种情形:编译期警告 + 运行时 transcript 才是完整故事。pto-diff 是用户与一次设备故障(或一份貌似合理的错误结果)之间唯一的屏障——因为 ptoas 下游所有环节(bisheng、运行时、硬件)都把 aliasing 后的 plan 视为合法。

复现步骤

fixture 与驱动都在 examples/ch11_exploit/。在任何装有 CANN 8.5、ptoas 已加入 PATH 的 910B2 主机上:

# 一次性:source CANN 环境,指向 LLVM 20(codegen 依赖)
source /usr/local/Ascend/cann-8.5.0/set_env.sh
export MLIR_SYS_200_PREFIX=/data/yuyijun/llvm20
export ACLRS_CANN_PATH=/usr/local/Ascend/cann-8.5.0
export ACLRS_SOC_VERSION=Ascend910B2
export PATH=/usr/local/bin/ptoas-bin:$PATH

# 用 `npu-smi info` 选一颗空闲芯片
ASCEND_DEVICE_ID=1 cargo run --release -p ch11_exploit

只要 good fixture 通过,二进制的退出码就是 0——bad 的崩溃是预期行为,表格已经报告了它,所以 CI 应当把表格与 golden transcript 对 diff,而不是仰仗退出码。退出 2 表示干净 fixture 出现了回归,这是构建或设备问题,值得在评估卫士前先排查。

11. 把安全卫士延伸到 ingested linalg 内核

11.1 Path A:给 ingested `ascend_tile` 的 projector

第 10 章把卫士跑在 .acl.pto 文件上——mlir_to_pto 后端产出的 PTO-MLIR。一个合乎情理的后续问题是:同一个卫士能不能对来自 ascend-rs 管线之外 的内核说些有用的话?具体说,就是来自第三方前端(例如 torch-mlir)的上游 linalg dialect MLIR。linalg 桥(第 7 章)消化这些内核,把它们降到我们的 ascend_tile 形式,再交给 mlir_to_cpp 去产出 AscendC。Ingested 内核在此之前一直是仓库里唯一一条 完全没有 Rust 侧安全分析的代码路径——“Rust safety card” 故事里的一个明显空档。

本节补上这个空档。把 §10.4 同样的 check_* 遍 pass 重新对准 ingress 路径,就能在 benchmarks/linalg/kernels_adversarial/ 下四个对抗性 fixture 中抓到三类 bug。这条路径是刻意做得极简的——约 300 行 projector 直接从 ascend_tile MLIR 合成一个 stage-2 Plan——并通过一个环境变量接入 ingress 驱动。

11.1.1 Ingress 为什么与 `.acl.pto` 不同

§10.2 的 stage-2 卫士从 ptoas --print-after-all 开始,那里每一个 tile 都已经具备完整的 (space, offset, rows, cols, dtype, blayout, slayout)。Ingested linalg 什么都没有:前端发出的是 llvm.func @kernel(...) attributes {hacc.entry},函数体是一连串 llvm.call @ascend_tile_<op>_<dt>(%args...) intrinsic——纯粹的 op-and-operand 汤,不含放置信息。

我们有两种诚实的选择:

Path A(本节):合成一个 naive stage-2 plan——给每一个 SSA 值分配它自己的 UB slot、offset 顺序递增——然后在这个 plan 上跑卫士。搭起来便宜,但价值有上限:能抓整块 tile 级别的问题,但永远看不到真实的 buffer 复用。
Path C(§11.2):把每一个 ingested 内核都通过真实的 mlir_to_pto → ptoas --print-after-all → parse_stage2 链路,直接复用 §10.2 的代码不改一行。精度更高,尤其在 blocked matmul 上,因为那里 Path A 会对容量做保守的 over-approximation。

Path A 是默认的快速路径;Path C 把完整卫士跑在 PlanMemoryPass 之后的 plan 上,能抓到一类 Path A 在结构上根本看不到的 bug。下文内容描述的是 commit 381340fc 实现下的 Path A;§11.2 讲 Path C。

11.1.2 一个改变“哪些 check 适用“的 SSA 性质

在讲 projector 之前,有一个关于输入格式的观察是基础性的:来自 torch-mlir 的 linalg 是 SSA 形式,而 SSA 形式 会自动给重名去重。源码层面的 y = x + x 降下来后变成一个 tile 被传给 linalg.generic 两次;而背靠背的 WAW(%t = f(%a); %t = g(%b))根本无法表达,因为第二次绑定会得到一个全新的名字。因此卫士的六遍 check 中有两遍对 ingested linalg 不适用:

check_aliasing 找的是不同 SSA 名字落在重叠 offset 上——SSA 形式在构造上就排除了这种情况。
原本的 check_linear_use WAW 规则查找“一次写后再一次写同一 slot“——SSA 形式会给第二次写重命名,所以触发不了。

能活着进到 projected plan 里的模式是 write-never-read:某个 op 产生了一个 SSA 值,后续没有任何 op 读它。这是源码层面的 aliasing 和源码层面的 WAW 经过 SSA 之后都会塌缩进去的规范形状。为了抓它,我们加了一遍新 check:

// crates/pto_to_rust/src/safety.rs
pub fn check_dead_writes(f: &PlanFunc, rep: &mut SafetyReport) {
    let mut read_slots:   BTreeSet<&Ssa> = BTreeSet::new();
    let mut written_slots: BTreeSet<&Ssa> = BTreeSet::new();
    for op in &f.ops {
        for s in op.reads()  { read_slots.insert(s); }
        for s in op.writes() { written_slots.insert(s); }
    }
    for w in &written_slots {
        if !read_slots.contains(w) {
            let producer = f.ops.iter()
                .position(|op| op.writes().iter().any(|s| s == w));
            let where_clause = producer
                .map(|i| format!(" (produced by op #{})", i))
                .unwrap_or_default();
            rep.violations.push(SafetyViolation::warn(
                &f.name, SafetyKind::DeadTile,
                format!("tile `{}` is written but never read{} \
                         — the producing op is dead code",
                        w.0, where_clause),
            ));
        }
    }
}

check_dead_writes 接进 check_all(所以手写 PTO 的覆盖率也因此提升——原来 50 个 case 的语料依旧全绿),同时也接进新增的 check_ingress 子集。

11.1.3 Projector

pto_to_rust::project(&ascend_tile_src) -> ProjectResult { plan, warnings }(约 300 行,位于 crates/pto_to_rust/src/ascend_tile_ingress.rs)遍历 ascend_tile MLIR 文本,给每一个 llvm.func @name ... attributes {hacc.entry} 发射一个 PlanFunc。规则刻意做得很小:

输入形式	产出的 slot / op
`%c = llvm.mlir.constant(N : i32)`	记录下的 shape 常量
`llvm.call @ascend_tile_load_<dt>(%buf, %r, %c) -> %t`	在 UB 里给 `%t` 分配下一个顺序 offset;产出 `TLoad` op
`llvm.call @ascend_tile_store_<dt>(%buf, %t, %r, %c)`	`TStore { tile: %t }`
`llvm.call @ascend_tile_<unop>_<dt>(%a) -> %t`,`<unop>` ∈ {exp/log/sqrt/rsqrt/tanh/abs/neg/sigmoid/silu/relu/softmax/rms_norm}	分配 `%t`;`TUnary { src: %a, dst: %t }`
`llvm.call @ascend_tile_<binop>_<dt>(%a, %b) -> %t`,`<binop>` ∈ {add/sub/mul/div/max/min}	分配 `%t`;`TBinary { a, b, dst }`
`llvm.call @ascend_tile_matmul_<dt>(%a, %b) -> %t`	分配 `%t`;`TMatmul`(所有参数都放在 UB——见下)
其他 `llvm.call @ascend_tile_*`	`TUnary` 占位 + 一条 warning

有两处设计选择值得明说:

每个 SSA 都有自己的 slot。 projector 不建模 buffer 复用——那件事由后面 mlir_to_cpp 的真实分配器负责。因此容量是 保守的 over-approximation:一个在真实分配器里能瘦到 64 KiB 的 kernel,在 projected plan 里可能被算成 512 KiB。这是刻意的权衡——对对抗性 fixture 而言,这种 over-approximation 正是我们想要的信号;对生产拟合过的 kernel 它会在 capacity 上产生误报(已记录的限制,Path C 的 to-do)。
Matmul 放在 UB,不在 L0。 从 ascend_tile 形式里恢复不出 Left/Right/Acc 的标注。projector 把所有操作数放进 UB,op 标成 TMatmul;但 check_ingress 子集不跑 check_op_constraint 和 check_matmul_bounds——跑了只会把每一个 matmul 都报成放置错误。那两遍 check 是 Path C 的领地。

check_ingress 刚好跑六遍中的五遍:aliasing + capacity + dead_tiles + dead_writes + linear_use。(前两个依然值得跑——aliasing 在 SSA-projected plan 上是空操作,等于 no-op;capacity 能抓到整块 tile 的严重超限情形。)

11.1.4 接进 ingress 驱动

linalg_to_ascendc 二进制(负责消化 linalg MLIR 产出 AscendC .cce 的工具)里多了一段 opt-in 块:

// crates/mlir_to_cpp_tests/src/bin/linalg_to_ascendc.rs
if let Ok(mode) = std::env::var("ACLRS_LINALG_SAFETY") {
    let projected = pto_to_rust::project(&ascend_tile);
    for w in &projected.warnings {
        eprintln!("linalg-safety [projector]: {}", w);
    }
    let spec = pto_to_rust::default_a5_910b2_cann85();
    let report = pto_to_rust::check_ingress(&projected.plan, &spec);
    let mut err_count = 0usize;
    for v in &report.violations {
        let sev = match v.severity {
            pto_to_rust::Severity::Error => { err_count += 1; "error" }
            pto_to_rust::Severity::Warning => "warning",
        };
        eprintln!("linalg-safety [{}] {}: {} (in `{}`)",
                  sev, v.kind.label(), v.message, v.func);
    }
    if mode == "error" && err_count > 0 {
        eprintln!("linalg-safety: {} error(s), aborting \
                   (ACLRS_LINALG_SAFETY=error)", err_count);
        std::process::exit(3);
    }
}

ACLRS_LINALG_SAFETY=1 以 advisory 模式跑:warning 打印出来,发射继续。
ACLRS_LINALG_SAFETY=error 把任何 Severity::Error 提升为退出码 3,与 .acl.pto 路径上 ACLRS_PTO_SAFETY=error 已有的约定保持一致。

还有一个同级小工具 linalg_safety_dump,把 projected 的 Plan(slots + ops)连同完整报告一起打印出来——当一个 ingress fixture 的行为出乎意料,想看 projector 到底搭出了什么时,很顺手。

11.1.5 四个对抗性 fixture

benchmarks/linalg/kernels_adversarial/ 下放了四份 .mlir 输入,每一份都刻意对准一类 bug。它们都很小(一个 function,≤3 个 op),这样 projected plan 是透明的。

Fixture	源码层面模式	期望的报告
`aliasing_same_tensor_twice.mlir`	`linalg.generic { %arg0, %arg0 } → add`	clean — SSA 把第二个操作数去重了
`capacity_overflow_1x131072.mlir`	对 1×131072 的 f32 tile(512 KiB)做 `exp`	`capacity` 错误 — UB 上限 192 KiB
`dead_tile_unused_intermediate.mlir`	`%t = exp(%a)` 算出来就丢掉;return `%a + %b`	在 `%t` 上报 `dead-tile` warning
`waw_double_write.mlir`	两个 `linalg.generic` 共享同一个 `outs`	在第一个 op 的 SSA 上报 `dead-tile` warning(SSA 已重命名)

用 ACLRS_LINALG_SAFETY=1 驱动每一个 fixture,逐字输出如下(在 adablue 上 commit 381340fc,release 版 linalg_to_ascendc):

$ for f in aliasing_same_tensor_twice capacity_overflow_1x131072 \
           dead_tile_unused_intermediate waw_double_write; do
    echo "=== $f ==="
    ACLRS_LINALG_SAFETY=1 crates/mlir_to_cpp_tests/target/release/linalg_to_ascendc \
      benchmarks/linalg/kernels_adversarial/$f.mlir /tmp/out.cce 2>&1 \
      | grep -E '^linalg-safety' || echo '(clean — no findings)'
  done
=== aliasing_same_tensor_twice ===
(clean — no findings)
=== capacity_overflow_1x131072 ===
linalg-safety [error] capacity: vec high-water 1048576 B exceeds capacity 196608 B
  (on Ascend910B2 (CANN 8.5)) (in `adv_capacity_overflow`)
=== dead_tile_unused_intermediate ===
linalg-safety [warning] dead-tile: tile `%t2` is written but never read
  (produced by op #2) — the producing op is dead code (in `adv_dead_tile`)
=== waw_double_write ===
linalg-safety [warning] dead-tile: tile `%t1` is written but never read
  (produced by op #1) — the producing op is dead code (in `adv_waw`)

aliasing fixture 报 clean 是故事里诚实的那一半:SSA 把 %arg0, %arg0 在 projector 看到之前就归并成了一个操作数,卫士通过保持沉默来说明这点。error 模式把 capacity finding 提升为 exit 3:

$ ACLRS_LINALG_SAFETY=error crates/mlir_to_cpp_tests/target/release/linalg_to_ascendc \
    benchmarks/linalg/kernels_adversarial/capacity_overflow_1x131072.mlir /tmp/out.cce
linalg-safety [error] capacity: ...
linalg-safety: 1 error(s), aborting (ACLRS_LINALG_SAFETY=error)
$ echo $?
3

11.1.6 复现实验

两套测试把这条链路端到端盖住;两套在 adablue-probe 上都是绿的:

$ cargo test -p pto_to_rust --test adversarial_ingress --release
test adv_aliasing_same_tensor_twice_clean            ... ok
test adv_capacity_overflow_flagged                   ... ok
test adv_dead_intermediate_and_dead_write_flagged    ... ok
test adv_waw_double_write_flagged                    ... ok
test ingress_aliasing_projects_cleanly               ... ok
test ingress_capacity_1x131072_flagged               ... ok
test ingress_dead_intermediate_caught_by_dead_write  ... ok
test ingress_waw_caught_as_dead_write                ... ok
8 passed; 0 failed

前四个跑的是手写的 PlanFunc 值(卫士本身);后四个跑的是 projector 本身——从 .mlir 文本出发,断言 project() + check_ingress() 产出预期的 Violation 集。所以加一个新的对抗性模式 = 一个 .mlir + 一个测试,不需要新的卫士代码。

11.1.7 这条路径抓不到什么

把边界明说出来会让主张落在“Rust safety 作用于 ingested 内核,在这些边界内“而不是“Rust 抓到一切“:

跨 op 的 buffer 复用 bug。 projector 给每个 SSA 都配自己的 slot,所以 mlir_to_cpp::analyze_kernel 真实分配器级别的冲突不经检查地滑过去。堵这个口子是 Path A 的后续功课:把复用决策反馈回 projector,让 capacity 数字和 aliasing 面与上线时的实际占用一致。
Matmul 放置 + blocked 形状。 projected plan 没有 Left/Right/Acc,所以 check_op_constraint 和 check_matmul_bounds 被刻意跳过。更糟的是,对 blocked matmul——即 mlir_to_pto 把大的 N 切成多段 per-op 小块——Path A 的 capacity check 汇报的是 pre-blocking 占用,这是误报。Matmul 的 fidelity 是 Path C(§11.2)的事;下文的 matmul_row_overflow fixture 是实证演示。
数值正确性。 卫士是结构性的;一份会产出错误结果但分配无误的 fixture 会通过。

即便有这些限制,四个 demo fixture 已经立下新的基线:ingested linalg 不再是未分析的输入。§10.4 的六遍 check 现在在 ascend-rs ingress 边界的两侧都能说话,而 ACLRS_LINALG_SAFETY=error 给了下游构建系统与 ACLRS_PTO_SAFETY=error 在自发 kernel 上相同的 advisory-或-hard 开关。

11.2 Path C:在 Post-PlanMem Plan 上跑完整的卫士

§11.1 对自身上限是诚实的:Path A 只能看到对 ascend_tile 文本做一遍遍历能告诉它的东西——看不到 buffer 复用,看不到 matmul 放置,也看不到 mlir_to_pto 自己的 shape 决策(tile blocking、Kb 选择、fractal packing)。有意思的问题是:要补这些空档,究竟需要一整套新分析,还是能把 §10.4 已有的 六遍卫士原样复用在一份已经内含这些信息的 plan 上?Path C 说可以——只需把 ingested linalg 走完真实的编译流水线,然后在 ptoas --print-after-all emit 出来、PlanMemoryPass 之后的 MLIR 上跑卫士。不加新 pass,不造新 plan 格式,只加一个新的 driver。

11.2.1 在 `adablue` 上纯主机运行

早期卡住 Path C 的假设是 ptoas 只在 910c 上(aarch64、NPU 硬件)。事实上不是——它也有一份 x86 构建在 adablue 上的 ~/ptoas-x86/bin/ptoas,且这个二进制在不接 NPU 的情况下也能为静态分析产出正确的 --print-after-all 输出。所以 Path C 与 NPU 执行是干净可分的:静态安全分析纯主机就能搞定,数值验证才需要 910c。这和一个 cross-compile 工程里 cargo check / cargo test 的分工一致。

11.2.2 五跳

 linalg.mlir                      ── 第 1 跳 ── linalg_to_ascend_tile
  │
 ascend_tile MLIR                 ── 第 2 跳 ── mlir_to_pto
  │
 .acl.pto (PTO-MLIR)              ── 第 3 跳 ── ptoas --print-after-all (x86)
  │
 stderr 中的 stage-2 MLIR         ── 第 4 跳 ── pto_to_rust::parse_stage2
  │
 post-PlanMem `Plan`              ── 第 5 跳 ── check_all(完整六遍)
  │
 SafetyReport

第 1、2 跳是已有的 ingress 路径。第 3 跳把未改动的 x86 ptoas 作为子进程调用,从 stderr 抓取 --print-after-all 输出。第 4、5 跳就是 §10.2 的流程,不改一行——同一套 parse_stage2、同一套 check_all、同一套 DeviceSpec。Path C 只提供把这几段串起来的水管。

还有一个独立的 probe 二进制(linalg_path_c_probe,单一 .rs 文件)按跳逐个打 PASS/FAIL,主要作为加新 fixture 时的诊断工具。生产使用走 driver(§11.2.4)。

11.2.3 Path C 强于 Path A 的地方

Path C 的卖点是“更紧的 capacity,能抓 matmul bounds“,关于当前 fixture 上究竟能证明什么,我们应当诚实。在当前所有 benchmarks/linalg/ fixture 上跑 Path C(commit b6db7cae),findings 表如下:

Fixture	第 3 跳 rc	第 5 跳 findings
`upstream/{add,exp,matmul,softmax}`	0	clean
`adv/aliasing_same_tensor_twice`	0	clean(SSA 去重 — 与 Path A 一致)
`adv/capacity_overflow_1x131072`	1	`ptoas: vec overflow, requires 8388608 bits while 1572864 bits avaliable`
`adv/dead_tile_unused_intermediate`	0	在 `%5`(post-PlanMem SSA)上报 `dead-tile`
`adv/waw_double_write`	0	在 `%3`(post-PlanMem SSA)上报 `dead-tile`
`adv/matmul_row_overflow`(16×16 × 16×65536)	0	clean — Path A 报 capacity 8 MiB;Path C 正确

最后一行是实证意义上的增量。Path A 的 projector 对 raw linalg 张量占用做直接加总:光输出 tile 16×65536×4 = 4 MiB 就已超过 910B2 的 192 KiB UB 上限,check_capacity 就此报 error。但 mlir_to_pto 会把 N=65536 切成多段每段 N=32 的 per-op chunk,再发射 pto.tmatmul。Post-PlanMemoryPass 的 plan 里根本没有这么大的 tile,Path C 报 clean——这是正确答案。这正是 §11.1.7 警告过的那条“保守 over-approximation“限制的实证;Path C 是补救方案。

从端到端 probe 还学到两件诚实的事:

ptoas 自身也有完整性边界。 在大形状(dims > 4095)上,ptoas 内置校验器比我们的 check_matmul_bounds(ROW < 2^16)更早拒掉 pto.tmatmul,所以在 ingested linalg 上后者多半是休眠的。该拒绝本身仍然会出现——Path C 把 ptoas rc≠0 视作 Error finding,违规信息照样能到达用户手里——只是来自与 §10.4 check 不同的层。
Path A 与 Path C 的 SSA 名字不同。 Path A 报 %t2;Path C 报 %5。两者都正确(同一个 tile,不同 dialect —— ascend_tile vs post-PlanMemoryPass MLIR),Path C 的名字与发射出来的 C++ 按字节对齐。

11.2.4 Driver 接线

ingress driver 在原本的 Path A 模式旁新增了 Path C 模式:

// crates/mlir_to_cpp_tests/src/bin/linalg_to_ascendc.rs
if let Ok(mode) = std::env::var("ACLRS_LINALG_SAFETY") {
    let abort_env = std::env::var("ACLRS_LINALG_SAFETY_ABORT")
        .ok().as_deref() == Some("1");
    let abort_on_error = abort_env || mode == "error";
    let err_count = if mode == "path-c" {
        run_path_c(&ascend_tile)   // 第 2..5 跳
    } else {
        run_path_a(&ascend_tile)   // project + check_ingress
    };
    if abort_on_error && err_count > 0 {
        eprintln!("linalg-safety: {} error(s), aborting", err_count);
        std::process::exit(3);
    }
}

旋钮如下:

环境变量	行为
`ACLRS_LINALG_SAFETY=1 \| path-a`	Path A(projector + `check_ingress`),advisory
`ACLRS_LINALG_SAFETY=path-c`	Path C(经 `ptoas` 的完整流水线),advisory
`ACLRS_LINALG_SAFETY=error`	Path A + 在 error 上中止(保持与 §11.1 兼容)
`ACLRS_LINALG_SAFETY_ABORT=1`	在 error 上中止,可与任一路径组合
`ACLRS_PTOAS_BIN=<path>`	覆写默认的 `$HOME/ptoas-x86/bin/ptoas`

run_path_c 把非零的 ptoas 退出码呈现为 Severity::Error finding,而不是硬崩。一个 ptoas 自己都拒绝的 kernel 本来就是 一个安全 finding——只不过是另一层抓到的。把它结构化成 error 让报告面保持统一。

11.2.5 Demo:在 `matmul_row_overflow` 上 Path A vs Path C

$ BIN=crates/mlir_to_cpp_tests/target/release/linalg_to_ascendc
$ ACLRS_LINALG_SAFETY=path-a $BIN \
    benchmarks/linalg/kernels_adversarial/matmul_row_overflow.mlir /tmp/a.cce \
    2>&1 | grep linalg-safety
linalg-safety [path-a] [error] capacity: vec high-water 8389632 B exceeds capacity
  196608 B (on Ascend910B2 (CANN 8.5)) (in `adv_matmul_row_overflow`)

$ ACLRS_LINALG_SAFETY=path-c $BIN \
    benchmarks/linalg/kernels_adversarial/matmul_row_overflow.mlir /tmp/c.cce \
    2>&1 | grep linalg-safety
(无输出 — Path C 报 clean)

Path A 用一个 8.3 MiB 的 capacity claim 产生误报;Path C 正确地看到 post-blocking 的 plan,保持沉默。同一份 kernel、同一套卫士 pass,输入是 MLIR 不同的那一层——而这正是 Path C 存在的全部意义。

11.2.6 复现实验

三个 integration test 把 driver 端到端盖住;它们以各种模式启动 release 二进制并对退出码 + stderr 做断言:

$ cargo test --manifest-path crates/mlir_to_cpp_tests/Cargo.toml \
    --test path_c_driver --release
test path_c_clean_upstream_add                         ... ok
test path_c_clean_where_path_a_overapproximates        ... ok
test path_c_surfaces_ptoas_capacity_overflow           ... ok
3 passed; 0 failed

测试会自动在 $ACLRS_PTOAS_BIN 或 $HOME/ptoas-x86/bin/ptoas 下寻找 ptoas,都找不到时以 skip 信息返回,因此没有 x86 ptoas 构建的 CI 也能保持绿灯。

11.2.7 非目标

Path C 并不声称 ingress 侧的卫士已经封掉所有缝隙:

check_op_constraint 与 check_matmul_bounds 在 ingress 路径上大多数时候处于休眠。 mlir_to_pto 在第 2 跳先过滤掉大多数违规形状,ptoas 再以比卫士 ROW < 2^16 更紧的 dims ≤ 4095 在第 3 跳过滤剩下的。这两遍 check 对手写 .acl.pto(§10.2 最初的目标)仍然有用,但在 ingress 路径上它们很少是第一道防线。
Path C 仍然信任 ptoas 自己的流水线。 如果 ptoas 静默接受一份其自身与我们的 pass 都抓不到的放置错误 plan,Path C 会报 clean。§10.3 “卫士抓出 ptoas 盲点” 的主张仍然只适用于卫士知道怎么读的那些槽位。
数值正确性依然不在范围内。 与 Path A 一致。

Path C 确实封掉的是 §11.1.7 点名的那个具体空档:blocked matmul 上 Path A 会保守地失败。任何未来的 matmul 密集型 ingested kernel(LLM MLP、attention projection、batched GEMM)现在都会拿到一个干净的结构性信号,而不是一条 capacity 误报——而且这一切通过在 lowering 里一个更有信息量的点上跑同一套 §10.4 的六遍卫士就能做到。没有新的卫士代码;价值来自把老卫士搬到更好的位置。

11.3 Worked Example：把 Softmax 一路跟到底

§11.1.5 与 §11.2.3 的 fixture 表把 add、exp、matmul、softmax 并列，覆盖面是公平的，但模糊了第 4 章的运行示例。本节单把 softmax_upstream_1x1024.mlir 拿出来，端到端走一遍两条 Path，再注入 ch11_make_bad_softmax.py 的 dead-tile 变体，呈现卫士给出的对比。同一对 fixture 也驱动 §11.6 的 demo 录制；本节是它的文字伴侣。

11.3.1 同一份 Softmax 的三种形态

fixture 是两行上游 linalg：

// benchmarks/linalg/kernels_upstream_shape_matched/softmax_upstream_1x1024.mlir
func.func @upstream_softmax_1x1024(%arg0: tensor<1x1024xf32>) -> tensor<1x1024xf32> {
  %0 = tensor.empty() : tensor<1x1024xf32>
  %1 = linalg.softmax dimension(1) ins(%arg0 : tensor<1x1024xf32>)
                                   outs(%0   : tensor<1x1024xf32>) -> tensor<1x1024xf32>
  return %1 : tensor<1x1024xf32>
}

经 hop 1 后变成 ascend_tile 形：一条 llvm.call @ascend_tile_softmax_f32(%in, 1, 1024) -> %t 加上配套的 load/store。经 hop 2 后变成 PTO-MLIR（pto.trowmax → pto.trowexpandsub → pto.texp → pto.trowsum → pto.trowexpanddiv，跨六个独立的 VEC tile）。在 Path C 的 hop 5 后，它已是一个为每个 tile 都标好 (space, offset, rows, cols, dtype) 的 stage-2 plan。

11.3.2 Path A 在干净 Softmax 上的结果

Path A 的投影器为每个 SSA 给一个独立的 UB 槽，跑 check_aliasing + check_capacity + check_dead_tiles + check_dead_writes + check_linear_use，报告：

$ ACLRS_LINALG_SAFETY=1 \
    crates/mlir_to_cpp_tests/target/release/linalg_to_ascendc \
    benchmarks/linalg/kernels_upstream_shape_matched/softmax_upstream_1x1024.mlir \
    /tmp/sm.cce 2>&1 | grep linalg-safety || echo '(clean — no findings)'
(clean — no findings)

这是预期结果：上游 linalg.softmax 降到一条 ascend_tile_softmax_f32 调用，投影器用「一个 tile 进、一个 tile 出」表达，没有别名、死写、容量超限的可能。

11.3.3 Path C 在同一份干净 Softmax 上的结果

Path C 把同一内核经 mlir_to_pto → ptoas --print-after-all 进一步降低，对 PlanMemoryPass 之后的 plan 跑全部六个 pass：

$ ACLRS_LINALG_SAFETY=path-c \
    crates/mlir_to_cpp_tests/target/release/linalg_to_ascendc \
    benchmarks/linalg/kernels_upstream_shape_matched/softmax_upstream_1x1024.mlir \
    /tmp/sm.cce 2>&1 | grep linalg-safety || echo '(clean — no findings)'
(clean — no findings)

Path C 的 plan 更丰富——六个 VEC tile 而非一个，带具体的 UB offset——但仍然干净。两条 Path 给出一致结论，但角度不同：Path A 说「源级 SSA 中没有别名模式」；Path C 说「分块后的放置中也没有别名」。两个都是值得做的安全声明。

11.3.4 对抗性变体：注入 48 个死 VEC tile

伴随脚本 blog/mdbook/scripts/ch11_make_bad_softmax.py 输出 ch11_sm_bad.acl.pto——同样的 softmax，在归约序列前加了 48 个额外的 pto.alloc_tile + pto.tload。每个额外 tile 都是 1×1024 f32（4 KiB），且没有任何下游 op 会读取它。因为它们是不同的 SSA 值，ptoas 的 PlanMemoryPass 可以随便放——而在这条 fixture 上它把若干个堆到了与活 tile %3 和 %11 相同的 UB offset。ptoas 以 rc=0 接受了程序；ccec 接受了 C++ 输出；bisheng 链接成可执行内核——而这个内核在运行时悄悄输出错误的 softmax 结果。

卫士对同一份 .acl.pto 的报告：

$ pto-diff --from-pto /tmp/ch11_sm_bad.acl.pto --ptoas /usr/local/bin/ptoas-bin/ptoas
[error] capacity: vec high-water 393216 B exceeds capacity 196608 B
        (on Ascend910B2 (CANN 8.5))
[error] aliasing: tiles `%3` and `%108` overlap at vec offset 0x1000
[error] dead-tile: tile `%108` is written but never read
... (94 more findings) ...
96 errors, 0 warnings

ptoas 退出码：0。卫士退出码：3。同一编译器、同一份输入字节——只有卫士抓到了 bug。这正是 demo GIF 捕捉到的对比。

11.3.5 为什么 Softmax 是整章的合适锚点

add 与 exp 适合做大小为一的测试，matmul 是 matmul-bound check 设计目标，但两者都不能让本章演练全部卫士被设计去抓的结构性模式。Softmax 可以：它有多步归约（dead-tile 与 dead-write 适用）、有多个中间 buffer（aliasing 适用）、且在 COLS 较大时会触发 capacity。注入死 tile 的变体是唯一一个 ptoas、ccec、bisheng 全部接受、而卫士正确拒绝的 fixture——这正是安全层存在的全部理由。

同一份 softmax 至此已在书中以五种形态出现：

形态	章节	说明
Rust 标量	§4.2	源级 `f32::exp()` 降为 `llvm.intr.exp`
Rust 向量	§4.3	`mlir_to_cpp` 与手写 AscendC 性能持平（16K 上 1.02× 略快）
Rust tile（PTO）	§4.5–4.6 + 附录 J §J3–J4	`mlir_to_pto` + `ptoas` 路径，双缓冲 2.4 µs/tile
上游 linalg ingress	§4.7 + 附录 J §J5	桥与 (b) 字节相同，端到端 <8% 时序差
对抗性 PTO 变体	§11.3 + 附录 J §J6	ptoas rc=0；卫士 96 errors 拒绝

五个入口、一份 fixture、一个判断：当到达 bisheng 的字节不安全时，卫士是说「不」的那一层。

12. 相关工作:Rust on GPU/NPU,以及与 NVIDIA 工具链的整合可能

12.1 Rust on Accelerators 全景

第 1 章包含了一个五行的表格,概要介绍了开源生态的全景。那张表对一个背景小节来说够用,但对于一次诚实的对比就太粗了——它把非常不同的设计塞进同一个“approach“格子里。本节把矩阵沿着真正重要的几个轴展开:每个项目替换了厂商技术栈中的什么,kernel 如何到达设备,是否在 Rust 自身类型系统之外提供任何编译期安全保证,以及宿主侧运行时是什么形态。

Project	Target HW	Authoring layer	What’s replaced	Runtime model	Safety beyond Rust	Maturity

从这个矩阵里可以看出几个 ch01 表格被压平掉的事实。

第一,只有两个项目尝试替换驱动之上的厂商技术栈:OxiCUDA 声称替换整个 CUDA 用户空间栈(从 cuBLAS 到 cuDNN);ascend-rs 替换 Ascend 的 kernel 编写语言并构建了自己的编译枢纽(ascend_compile),但运行时仍然调用 ACL / CANN。其它五个项目给你一种更安全的方式来表达 kernel,但保留了厂商的库。

第二,运行时模型干净地一分为二。rust-cuda、rust-gpu、krnl 和 ascend-rs 都走 AOT:kernel 在 build time 编译为机器码产物。cudarc、OxiCUDA 以及 wgpu 的 compute 路径都使用运行时编译(经由 nvrtc、运行时 PTX 发射,或第一次 draw 时的 shader 编译)。AOT 给你可复现性,并允许在 binary 构建之前跑安全分析;JIT 给你灵活性(形状特化、与目标相关的调优)。第 10 章和第 11 章只在 AOT 模型下才说得通——你没办法在还没发射的 PTX 上跑 check_all。

第三,这是让 ascend-rs 的位置与众不同的地方:没有别人在它生成的低层 IR 上提供编译期安全卫士。其他每个项目的安全叙事都是“Rust 借用检查器,加上对厂商运行时的安全 API 包装“。这是真实的贡献——CUDA C++ 的 aliasing 和 UAF bug 极为常见——但它对生成 kernel 的内存布局没有任何陈述。第 10 章和第 11 章对那个布局是有所陈述的:它们在 ptoas 产生的 stage-2 计划上跑 check_aliasing、check_capacity、check_dead_writes、check_slayout_consistency。这是一种厂商工具链本应自带、但实际并没有的分析;ascend-rs 把它作为旁路提供出来,作为厂商工具链以 rc=0 接受的 kernel 的一张“Rust 安全卡片“。

12.1.1 ascend-rs 落后于他人的部分

一节诚实的全景必须把差距点出来。在上面的矩阵里有三处可见的差距。

Library coverage. OxiCUDA 声称提供 cuBLAS、cuDNN、cuFFT、cuSPARSE、cuSOLVER、cuRAND 的等价物。ascend-rs 有一个 ascend_std 标准库和附录 E 中的 kernel 清单,但没有等价于完整 DNN 库的东西——我们的 DNN 故事是“把你需要的算子作为一个 Rust tile kernel 写出来“,而不是“use ascend_dnn::conv2d“。对于心智模型是“拿起 DNN 库就跑“的用户来说,ascend-rs 需要更多自行组装。

Ecosystem. rust-cuda、rust-gpu、wgpu 和 cudarc 都有多年在 crates.io 上的存在、下游用户和 bug report。ascend-rs 处于开发中(第 1 章的 status 列已说明),并且驻留在私有仓库里;公开的 yijunyu/ascend-rs 只放产物(参见仓库说明)。“Widely used“是我们目前还做不出的声明。

Target breadth inside NVIDIA. rust-cuda / rust-gpu / OxiCUDA 都把 NVIDIA 当作一等公民。ascend-rs 有一个 mlir_to_gpu 后端发射 CUDA C,但它属于次级 codegen 出口,并非主攻方向。如果你的主目标就是 NVIDIA,那些 NVIDIA 优先的项目在 NVIDIA 特定打磨上仍然领先于我们。

本章主张整合而非竞争,正是因为上面的几个轴在很大程度上是正交的。OxiCUDA 的 library coverage 与 ascend-rs 的安全卫士本来就是两件不同的工作,完全可以叠加在一起。

12.2 与 OxiCUDA 的逐项对比

OxiCUDA 值得专门一节,因为在相关项目里,它是最容易和 ascend-rs 混淆的:两者的简介里都有“替换厂商技术栈“的说法,两者都把 Rust 作为编写表层。这种混淆是表层的,值得讲清楚。

12.2.1 目标硬件

OxiCUDA 是 NVIDIA 优先。v0.1 公告把 NVIDIA CUDA 列为主要后端,Metal / Vulkan / WebGPU / ROCm / Intel Level Zero 作为附加后端。共享抽象似乎是“一个 kernel + 一份运行时库“,由各厂商后端实现它。

ascend-rs 是 Ascend 优先。Ascend 910B2 / 310P 上的 CANN 8.5 是主目标;crates/rustc_codegen_mlir/src/ 中的 14 个 mlir_to_*.rs 是次级 codegen 出口,共享 ascend_tile_* MLIR dialect 作为公共 IR。这些出口按字母顺序为:aie、bang、cpp、csl、gaudi、gpu、hexagon、linalg、msl、musa、nki、pto、spirv。对一个 NVIDIA 用户而言,mlir_to_gpu 存在并能发射 CUDA C,但没人声称它和一个专门面向 NVIDIA 的项目一样打磨成熟。

12.2.2 替换了什么

这是两个项目在 headline 上看起来相似、在细节上分道扬镳的轴。

OxiCUDA 替换的是 CUDA SDK 运行时栈:你不安装 nvcc,你不安装 CUDA toolkit,你不写 .cu 文件。剩下的唯一运行时依赖是 libcuda.so(驱动)。PTX 在运行时从 Rust 数据结构生成并通过 Driver API 交给驱动。替换是横向的,跨越用户空间的库。

ascend-rs 替换的是 kernel 编写语言,并提供独立的 编译枢纽(ascend_compile),但不替换 CANN / ACL。替换是纵向的,在 kernel 编程切片之内:你的 kernel 源码是 Rust 而不是 AscendC C++,然后 rustc_codegen_mlir 把它经由 MLIR 下沉到 AscendC,再由 bisheng 产出 NPU binary。CANN 仍然是运行时。我们没有重写 cuBLAS 在 Ascend 一侧的对应物(aclBLAS)。

这种差异对部署是有影响的。OxiCUDA 用户的 NVIDIA 机器只配驱动加上编译好的 Rust binary。ascend-rs 用户的 910B2 机器需要安装 CANN 8.5,加上 Rust binary 和 codegen 产物库。前者更激进;后者更保守,在真实的厂商硬件上落地更快。

12.2.3 编译模型

OxiCUDA 在运行时生成 PTX。kernel 路径上没有 .cu 文件、磁盘上没有 .o 文件;PTX 字符串在进程内由 Rust 类型构建,提交给 Driver API,module 句柄存入缓存。这种方式在精神上与 cudarc 加 nvrtc 类似,但通过直接发射 PTX 砍掉了 nvrtc 依赖。

ascend-rs 是 AOT 编译。在 cargo build 时,rustc_codegen_mlir 产出 MLIR,mlir_to_cpp 或 mlir_to_pto 产出 C++ 或 PTO-MLIR,bisheng(经由 ascend_compile)产出 NPU 目标代码,最终链接到 kernels.so,host 在运行时通过 libloading 加载。第 7 章给出完整的图。

两种模型严格意义上没有谁更好。AOT 让我们能跑一个编译期安全卫士;JIT / 运行时发射让 OxiCUDA 能基于 Rust 代码只在运行时才知道的形状做特化。自然的综合方案——12.3 节会接上——是:即便 PTX 是运行时发射的,只要在 launch 之前有一个时刻能将其冻结,AOT 安全分析仍可以应用到这份 PTX 上。

12.2.4 安全叙事

两个项目在编写侧都说“类型安全、内存安全的 Rust“,并且在 API 表层都兑现了这个声明。Rust 的借用检查器在 host 一侧抓它能抓到的东西。

ascend-rs 通过第 10 章和第 11 章的安全卫士又往前迈了一步。那两章描述了在 ptoas 产生的 stage-2 计划上运行的六个 pass:check_aliasing、check_capacity、check_dead_writes、check_slayout_consistency,以及另外两个。它们抓的是 ptoas 自己以 rc=0 接受的 bug——也就是厂商工具链产出一个 binary、这个 binary 能跑、但悄悄破坏数据的那一类 case。这是一类没有“对运行时的安全包装“能抓到的 bug,因为 unsafety 存在于包装之下,在生成 kernel 的内存布局里。

截至本文撰写时,OxiCUDA 的 v0.1 还没有为它发射的 PTX 文档化对应的分析。这无意贬低——v0.1 就是 v0.1,该阶段的重点本就是 library coverage,而把分析往后排是合理的取舍。这恰恰是一个整合机会,12.3.3 节会讲。

12.2.5 范围

OxiCUDA 在框架层面更宽:其公告把计算图、GPU 训练、推理和强化学习都列入目标。一个有这种野心的 v0.1 是“先把表层占住,再慢慢打磨“。

ascend-rs 更窄:我们提供编译器后端、标准库、HAL、安全的运行时包装,以及一份经过验证的 kernel suite(DeepSeek-R1-Distill-Qwen-1.5B 在 910B2 上端到端 decode 180+ tok/s,跨 MultiKernelBench 类目 500+ 编译通过的 kernel——见第 9 章)。我们不提供训练循环或 RL 框架。有人可以在 HAL 之上构建这些,但那不是我们已经发布的东西。

12.2.6 一句话对比

OxiCUDA:删掉 CUDA SDK,运行时从 Rust 发射 PTX,覆盖 NVIDIA library surface。

ascend-rs:用安全 Rust 写 NPU kernel,经 MLIR 穿过厂商工具链,证明厂商工具链自己证不了的安全属性。

两者是各自独立的项目,彼此之间也没有直接的竞争关系。下一节论证它们可以在接缝处接到一起。

12.3 NVIDIA 侧的整合机会

crates/rustc_codegen_mlir/src/mlir_to_gpu.rs 自我们启动多 vendor 出口以来就在 tree 里,它已经是落地代码,而非纸面设想。给定驱动 Ascend 路径的同一份 ascend_tile_* MLIR,它发射一个可被 nvcc -arch=sm_80 或 clang++ --cuda-gpu-arch=sm_80 编译的 .cu 文件。该文件顶部的映射表覆盖了核心算子——ascend_tile_load_f32、_store_f32、_add_f32、_sub_f32、_mul_f32、_exp_f32、_softmax_f32、_reduce_max_f32、_reduce_sum_f32、_scale_f32——通过直接的 CUDA kernel 模式,其中 matmul_f32 当前作为 cuBLAS-SGEMM 的占位注释发出。

以此为起点,有四个整合机会自然浮现。它们按今天可落地的具体程度排序。

12.3.1 短期:`mlir_to_gpu` + `cudarc` host 运行时

今天 mlir_to_gpu 产出一个 .cu 字符串。这个字符串被喂给什么是用户自己的事。ascend-rs 不提供 NVIDIA host 运行时。

短期整合是把 .cu 输出连接到 cudarc 的安全 driver/runtime 绑定:

用户用 ascend_std tile API 写 kernel,和 Ascend 完全一样。
rustc_codegen_mlir 配合 ACLRS_CODEGEN_PATH=gpu 发射 .cu。
nvcc(或 clang++ --cuda-gpu-arch=sm_80)编译为 .ptx 或共享库。
在 host 一侧,一个小的 ascend_hal CUDA 后端(类似于 crates/ascend_hal/ 中已经存在的、被 CLAUDE.md 引用的 cuda 后端)使用 cudarc 进行设备初始化、分配、stream 创建和 launch。

用户得到一份 Rust 源码:设 ACLRS_CODEGEN_PATH=pto 跑 910B2,设 ACLRS_CODEGEN_PATH=gpu 跑 NVIDIA。host 一侧是 cudarc 的事——一个 API 维护良好、有测试套、有数千下游用户的 crate——而不是我们的事。

这是能跑通真实端到端路径的最小整合,也是有人最可能先做原型的那条路。瓶颈很平凡:mlir_to_gpu 的 matmul 路径需要把 cuBLAS 调用补上(今天还是 TODO 注释),ascend_hal CUDA 后端需要更多测试覆盖(cudarc 依赖已经存在,只是藏在 feature gate 之后)。两者都属于纯工程问题,无关研究。

12.3.2 中期:把运行时 PTX 发射作为 `nvcc` 的替代评估

上一步骤 3 中的 nvcc 依赖,与 CANN 的 bisheng 在 Ascend 一侧带来的同类构建期依赖性质一致。这种依赖是站得住脚的——两者都是厂商的官方编译器——但它也是最大的整合摩擦:CI 机器需要 toolkit,Docker 镜像膨胀,nightly build 在厂商升级时挂掉。

OxiCUDA 的运行时 PTX 发射是自然的替代。如果 mlir_to_gpu 后端不发射 CUDA C,而是直接发射 PTX(经由一个 mlir_to_ptx,或穿过 LLVM 的 NVPTX target),那么 nvcc 依赖消失,部署画像就匹配 OxiCUDA 已经在自己一侧做的事。

有两条路径:

扩展 mlir_to_gpu,通过 mlir-sys 调用 LLVM 的 NVPTX 后端,直接把 MLIR 下沉为 PTX。这把 codegen 完全留在 ascend-rs 内部。
与 OxiCUDA 合作:ascend-rs 把 tile MLIR 下沉到一个中间形态(LLVM dialect,或 OxiCUDA 的 Rust-AST 数据结构),然后由 OxiCUDA 现有的 PTX 发射器接管。

方案 2 值得考虑,因为 OxiCUDA 已经解决了“为现代架构生成有效 PTX“这个问题,并在维护那个 PTX 发射器。方案 1 更自洽,但意味着我们要扛起 PTX 生成的复杂度。

两条路径之间没有明显赢家;正确答案取决于 OxiCUDA 的 API 有多稳定,以及 mlir_to_gpu 实际需要 NVPTX 表面积的多大部分。一次探针——为 softmax kernel 用两种方式生成 PTX,diff 输出,在真实 NVIDIA GPU 上做基准——是自然的下一步。

12.3.3 中期:把第 11 章的安全卫士跑在 PTX 上

这是新颖度最高的机会。第 11 章安全卫士的 pass——check_aliasing、check_capacity、check_dead_writes、check_slayout_consistency——逻辑上并不是 Ascend-specific 的。它们运行在一个 stage-2 计划之上:一份扁平的 tile 列表,每个 tile 携带 (space, offset, rows, cols, dtype, blayout, slayout) 元组,加上其上的依赖图。check_aliasing 中没有任何东西知道它是跑在 PTO-MLIR 上而不是别的 IR 上。Ascend-specific 的部分都在 parser(parse_stage2)里,它从 ptoas --print-after-all 的输出产出该计划。

一个能从 PTX 产出等价 stage-2 计划的 parser——从 shared-memory 分配、从 ld.global / st.global 访问、从 warp 级 shuffle 模式——能让同样的六个 pass 跑在 NVIDIA kernel 上。Ascend 安全卫士抓到的每一种“我的 kernel 能跑但答案不对“的 bug,在 NVIDIA 一侧都有对应物(shared-memory bank 冲突、aliased __shared__ 数组、对每 SM 48 KB 或 100 KB 上限的容量超界)。

具体地:

写一个 parse_ptx_stage2,产出与今天 parse_stage2 产出的同款 Plan 结构,但来源是 PTX 而非 PTO-MLIR。
在结果上跑现有的 check_all(plan)。
把它接到一个环境变量(镜像 ACLRS_PTO_SAFETY)——例如 ACLRS_PTX_SAFETY=error / =warn / 不设。

parser 是难的部分;check 直接复用。这是面向任何 PTX 发射型 Rust-GPU 项目(OxiCUDA 或其它)的一份干净的联合贡献。今天没有任何这类项目在它生成的 PTX 上提供编译期安全分析。

12.3.4 长期:共享一份 tile IR

在栈的顶端,ascend_tile_* intrinsic 与 OxiCUDA(或 rust-cuda、或 rust-gpu)用作 tile 抽象的东西在解决同一个问题:用一种可被下沉到具体厂商的形式,描述一块矩形的数据 tile 以及其上的一个操作。我们在 crates/rustc_codegen_mlir/src/mlir_to_*.rs 中有 15 vendor backends;每一个都消费同一份 ascend_tile_* MLIR。

长期整合是把这份 tile dialect 做成一个独立产物——一个 MLIR dialect 加一份参考下沉——并邀请其它项目下沉进入它(OxiCUDA 的 Rust AST → tile MLIR → PTX)或下沉离开它(tile MLIR → SPIR-V → Vulkan,正如 mlir_to_spirv 已经做的)。到那时图景是:一份 tile IR、N 个 frontend、M 个 backend,以及一个夹在两端之间的安全卫士。

这是四个机会里最具推测性的一个,也是最需要看到真实用户需求才值得承担维护成本的那个。把它列在这里,是因为前三个机会自然把方向推向这里——如果你已经在共享一份 host 运行时(12.3.1)、共享一份 PTX 发射器(12.3.2),并共享一份安全卫士(12.3.3),那么共享所有这些一起下沉的源头 IR,就只是把这幅画补完了。

12.4 ascend-rs 能反哺生态的部分

如果整合发生,贡献是双向的。ascend-rs 中可以脱离 Ascend 上下文复用的部分,按就绪度递减排序:

安全卫士。 六个 pass 在 pass 这一层已经与 Ascend specifics 解耦。一个 PTX 的 stage-2 parser 即可让它们对 NVIDIA 解锁。
ascend_compile 编译枢纽模式。 今天它分发到 bisheng,但其中的三个验证 pass 与双标志基础设施是可以一般化的:第 7 章描述了一个 C++-to-binary 的枢纽,而 CUDA C、SYCL、HIP 与 AscendC 都共享这条编译流水线的形态。一个把 ascend_compile 结构因式分解出来的多 vendor compile crate,本身就是一个合理的 Rust crate。
MLIR tile dialect。 已经有 15 个 vendor 后端共享它。把它从 ascend-rs 仓库拆出来属于工程任务,无关研究。
Rust 侧的 kernel 语料。 跨 MultiKernelBench 类目 500+ 个 kernel,从 softmax 到 DeepSeek 的 MLA attention,都用安全的 tile-API Rust 写出。对任何想要测试套的项目,这是一个起点。

不能搬迁的部分:CANN 相关的细节(pipe barrier、L0/L1/UB 内存布局、SoC 版本守卫)、ACL 运行时包装、aiv_kernel 宏中 AscendC 特定的 ABI,以及任何提到 910B2 的部分。这些占代码库的 ~30%;另外 ~70% 是通用有用的。

12.5 本章不是什么

值得明确说出本章刻意不主张的几点。

它不主张 ascend-rs 在某个基准上赢过了 OxiCUDA——它们没有提供可比的基准,即便有,目标硬件也不同。

它不主张 OxiCUDA 在运行时生成 PTX 是错的。这本就是一个有真实优势的合理设计选择;12.3.2 节把它当作整合机会来讨论,从不视其为设计缺陷。

它不主张第 11 章的安全卫士今天就能在 PTX 上工作。12.3.3 节把它列为中期机会是有原因的:PTX 的 stage-2 parser 还没写。本章所主张的范围只到 pass 可以移植这一层;parser 本身的工作量是另一回事。

它不主张 rust-cuda、rust-gpu、cudarc 或 krnl 已经过时。它们各自占据设计空间中一个独特的点(见 12.1),对于它们当初被构建出来要服务的用例,它们仍然是正确答案。

本章主张的是窄而(我希望)立得住的:ascend-rs 与 NVIDIA 一侧的 Rust 项目,正在用互补的强项解决重叠的问题;整合面已经在今天的代码里可见(mlir_to_gpu + cudarc + 第 11 章的安全卫士);一次认真把它们接到一起的努力,会产生比任何一个单独项目都更强的故事。

13. 下一步:路线图与展望

当前状态

ascend-rs 已经远远跨过了前面几章覆盖领域中的 alpha 阶段。本章的路线图只关注剩下的事情——那些第 2–7、9、10、11、12 章还没有演示过的工作。已经演示过的东西都按“已交付“处理,这里不再重复。

宿主机 API:alpha 完成。ACL、内存、stream、event、HCCL、DVPP、profiling、BLAS 都有安全的 Rust 封装。
ascend_compile crate:独立编译库,提供 Rust API、C ABI、CLI、Python 绑定——AscendC C++ 到 NPU 二进制的唯一统一路径,服务栈中所有前端(架构见 §7.1.1)。
设备运行时:1565 个 Rust NPU 内核(489 个编译测试 + 16 个可部署),413 个在 Ascend 910B3 上通过 NPU 正确性验证,覆盖 MultiKernelBench 全部 17 个类别。
PyPTO / PTO-MLIR 路径:已集成。emitter(mlir_to_pto)→ ptoas 0.26 → AscendC → bisheng。通过这条路径,DeepSeek-R1-Distill-Qwen-1.5B 在 910B2 上端到端 decode 达到 114–187 tok/s(第 10 章)。
安全卫士:已交付(第 11、12 章)。在 ptoas 产出的 stage-2 plan 上跑六个 check_* pass;Path A + Path C 两种 ingress 方案覆盖来自第三方前端的 linalg 内核;能捕获 ptoas 自己 rc=0 通过、但 PlanMemoryPass 放置有 bug 的情况。

下面是三条方向——不是任务清单。每一条都吸收了之前分散追踪的多条线索。

方向一:闭合内核编写回路——双缓冲、迭代器、调试信息

核心 MLIR 后端在第 3–5 章所覆盖的运算上已经功能完备:算术、归约、一元数学、标量-向量、16 种激活、17 个组合算子、cube engine 矩阵乘(含硬件 L1→L0B 转置)、以及编译期防止 UB/L1/L0 混用的类型安全 buffer newtype。剩下的是表达力和开发体验问题,不是新运算。

基于 queue 的流水线(TQue)。当前 codegen 发射直线型内核并自动推断 pipe_barrier(§7 的 BufDepTracker)。切换到基于 TQue 的双/三缓冲能让 DMA 与 compute 重叠,这是 memory-bound 内核下一步的性能空间。DeepSeek decode 的 lm_head 已经通过手工分块利用了这一点(§9 chunk sweep);这件事应该由编译器自动完成。
内核代码里的迭代器组合子。map、filter、fold、zip、enumerate——内核作者期望能写的形状。这些需要 mlir_to_cpp / mlir_to_pto 里对应的 codegen 支持;运算本身已经存在。
调试信息。MLIR 后端当前不发射任何 DWARF。加上之后,就能用 gdb/lldb 在生成的 AscendC 里单步调试,这正是“能跑但结果错“且通过 oracle 的内核当前缺失的那块。

这些是工程而不是研究。每一条都是有边界的工作,有清晰的验收标准:cargo run 一个用 .iter().map().sum() 的内核,看到生成的 .cpp 正确使用 ReduceSum;在调试器里单步一个内核的 UB 访问。

方向二:`ascend_compile` 作为通用编译后端

第 7 章的架构已经命名了我们自己的 mlir_to_cpp / mlir_to_pto 之外的四个前端:TileLang、Triton-Ascend、torch.compile、PyPTO。每一个都产出 AscendC C++;每一个当前都直接调用 bisheng,标志不一致,也没有验证。这条方向的路线图更多是接线而不是写新代码:

TileLang 今天驱动一个无验证的 subprocess.run(bisheng, ...);通过 Python wrapper 替换为 ascend_compile,TileLang 就能自动获得目标检测、三项验证 pass、以及与我们自己内核一致的标志路径。
Triton-Ascend 把它的 IR 下沉到 AscendC;最后一公里对任何 C++ 前端都是相同的。
带 Ascend 后端的 torch.compile 可以通过 ctypes 调用 libascend_compile.so,完全绕开 Python-to-Rust 依赖。
PyPTO,当它与 CANN 一起发布时,是最自然的用户:它那 ~90 条的虚拟 ISA 已经下沉到 AscendC,通过 ascend_compile 跑一遍就意味着安全卫士能看到同一批 plan。

交付物不是更多的后端——而是昇腾生态里更少的定制编译流水线。LLVM 的图景适用于这里:多前端,一个经过验证的后端。

这条方向也为方向三铺路,因为它为安全卫士建立了一个公共的拦截点。

方向三:扩大安全卫士的覆盖面

第 11 章和第 12 章分别把 oracle 交付到了 PTO-MLIR 和 ingested linalg 上。自然的下一步是保留检查 pass、替换parser:

PTX(NVIDIA)。第 12 章 §12.3.3 描述了这条路径:六个 check_* pass 在逻辑上并非 Ascend-specific——它们作用于一个由 (space, offset, rows, cols, dtype, blayout, slayout) 元组组成的 stage-2 plan。写一个 parse_ptx_stage2 就能让它们跑在 mlir_to_gpu 发射的 PTX 上、跑在 OxiCUDA 这样的 runtime-PTX 项目上、或者跑在任何其他源头上。shared memory bank 冲突、__shared__ 数组别名、对 48 KB 或 100 KB per-SM 限额的超限,都能映射到现有的 check 上。
通过共享 tile IR 扩到其他厂商。crates/rustc_codegen_mlir/src/ 今天有 15 个 mlir_to_* 后端(aie、bang、cpp、csl、gaudi、gpu、hexagon、linalg、msl、musa、nki、pto、spirv……)。每一个都从同一个 ascend_tile_* dialect 下沉。直接读这个 dialect 的 parser——在任何 vendor-specific lowering 之前——给 oracle 对每个目标最早、最干净的切入点。
向 Rust 上游贡献。upstream-tier3/ 下已经准备好了一份 Tier-3 目标规格(davinci-huawei-none):目标三元组、ABI、platform-support 文档、mod.rs/platform-support.md/bootstrap/sanity.rs 的补丁、以及社区材料(Zulip 帖子、可选 MCP 草案、PR 描述)。参与计划:(1) 在 Zulip #t-compiler/help 上就 triplet 名称征求反馈,(2) 如果新颖的 MLIR codegen 需要编译器团队共识就提交 MCP,(3) 向 rust-lang/rust 提交 draft PR。Tier-3 门槛最低——不需要 RFC,不需要 CI,单个 reviewer 批准即可——且我们的 in-tree 改动不含任何专有代码。

三条小节背后潜伏着一个长期问题:ascend_std 里的 #![no_core] 重实现,最终能否在上游 target 之上被 -Zbuild-std=core 替代?那将切掉这个项目当前最大的一笔维护税。

社区参与

ascend-rs 正在等待开源决定。一旦公开,贡献入口包括:

新增 ascend_std intrinsic——遵循 extern "C" stub + mlir_to_cpp handler 模式。
内核语料——写真实的内核,反馈 codegen 的缺口。
宿主机 API 覆盖——CANN 的 API 比我们封装的要多。
前端集成——如果你在做 TileLang、Triton、PyPTO、或 torch.compile 的 Ascend 路径,尝试把你的编译步骤换成 ascend_compile 并反馈问题。
Oracle 的 parser——为另一种 IR(PTX、SPIR-V、LLVM NVPTX)写一个 stage-2 parser,六个 check_* pass 就白送给你。

总结

ascend-rs 项目证明了在 NPU 编程领域实现内存安全是可行的，而且不需要牺牲性能。通过 Rust 的所有权系统、生命周期和 RAII 模式，我们在编译期消除了一整类内存安全错误——而这在传统的 C++ NPU 编程中只能依赖程序员的经验和纪律。

从 Hello World 到向量化 softmax 内核，我们看到了一个从源码到 NPU 执行的完整流程：Rust 源码 → MLIR 中间表示 → 带 AscendC 向量指令的 C++ → NPU 二进制 → 设备执行 → 安全的结果回传。在 Ascend 910B3 硬件上 413 个测试全部通过（0 失败、0 崩溃），基准测试证实 Rust 向量化内核完全匹配手工优化的 C++ 性能——零额外开销。

随着 ascend_compile crate 的引入，ascend-rs 的影响力已扩展到 Rust 内核开发者之外。通过提供带有 C ABI 和 Python 绑定的独立、经过验证的编译库，该项目使更广泛的昇腾生态系统——TileLang、Triton、PyTorch 以及未来的编译器框架——能够共享同一个经过充分测试的编译后端。同样的验证检查能力（捕获缺失的同步屏障和缓冲区溢出）现在保护着来自任何来源的内核。

方向是明确的：为每一位昇腾 NPU 用户带来安全保障，无论他们是编写 Rust 内核、Python DSL 还是集成编译器工具链——并在此过程中使整个生态系统更加可靠。

附录：GPU/NPU 生态中的真实内存安全漏洞

第 6 节中的六组内存安全案例研究展示了 Rust 能预防常见错误的结构性模式。然而，加速器代码中的内存安全不仅是理论问题——它已导致在野外被积极利用的零日漏洞、生产环境崩溃和安全事件，涉及所有主要 GPU/NPU 厂商。本附录记录具体的、可引用的案例。

A.1 ARM Mali GPU：被间谍软件利用的 Use-After-Free（CVE-2023-4211）

ARM Mali GPU 内核驱动的 VMA 跟踪中存在 use-after-free 漏洞，允许在数十亿安卓设备上进行权限提升。攻击者可通过 munmap() 分割多页跟踪 VMA，导致清理例程在记账仍在进行时将 kctx->process_mm 置空。Google TAG 确认此漏洞被商业监控软件供应商积极利用。Rust 的所有权模型从根本上防止 use-after-free——已释放的 VMA 会被消费/丢弃，任何后续引用都会产生编译期错误。

A.2 ARM Bifrost/Valhall GPU：被积极利用的零日漏洞（CVE-2024-4610）

ARM GPU 驱动中的另一个 use-after-free，影响 Bifrost 和 Valhall 架构（r34p0-r40p0）。CISA 确认该漏洞在数亿智能手机和嵌入式设备上被在野利用。Rust 的借用检查器强制执行独占可变访问，使悬垂引用模式不可能发生。

A.3 NVIDIA GPU 驱动：越界写入（CVE-2024-0090）

NVIDIA Linux/Windows GPU 显示驱动中的越界写入漏洞，允许权限提升。Rust 的切片访问边界检查会通过安全的 panic 捕获此问题，而非静默的内存损坏。

A.4 AMDGPU Fence：Use-After-Free 竞态条件（CVE-2023-51042）

Linux AMDGPU 驱动的 amdgpu_cs_wait_all_fences() 中的竞态条件允许代码访问已释放的 fence 对象，导致内核崩溃和潜在的权限提升，Red Hat、SUSE 和 Ubuntu 紧急发布补丁。Rust 的所有权模型使数据竞争成为编译期错误——fence 将由 Arc<Mutex<...>> 保护，同时防止 use-after-free 和底层竞态。

A.5 NVIDIA CUDA Toolkit：整数溢出导致堆缓冲区溢出（CVE-2024-53873）

NVIDIA CUDA Toolkit cuobjdump 工具中的九个漏洞，由 cubin 文件解析时的整数溢出导致堆缓冲区溢出。Rust 的检查算术（debug 模式溢出 panic，显式包装需要 wrapping_mul）防止整数溢出，Vec/切片边界检查防止后续堆损坏。

A.6 Qualcomm Adreno GPU：三个被定向攻击利用的零日漏洞（CVE-2025-21479/21480/27038）

Qualcomm Adreno GPU 驱动中的三个零日漏洞，包括未授权 GPU 微码命令执行和渲染期间的 use-after-free。在针对数十亿安卓设备的定向攻击中被积极利用。Rust 的内存安全保障防止 UAF，所有权模型约束对 GPU 资源的操作。

A.7 PyTorch CUDA 内核：静默越界访问（Issue #37153）

在 PyTorch 的 Reduce.cuh 中，对标量输入访问 iter.shape()[0]（此时 iter.shape() 返回空数组）导致越界内存读取。这导致了极难复现或诊断的间歇性测试失败——典型的静默数据损坏模式。Rust 的切片索引在空切片访问时 panic，而非静默读取垃圾内存。

A.8 TensorFlow GPU 内核：反复出现的堆缓冲区溢出（CVE-2023-25668, CVE-2020-15198, CVE-2019-16778）

TensorFlow GPU 内核中的堆缓冲区溢出模式：QuantizeAndDequantize 越界读取（CVE-2023-25668），SparseCountSparseOutput 张量形状不匹配（CVE-2020-15198），UnsortedSegmentSum 将 int64 截断为 int32 产生负索引（CVE-2019-16778）。这些漏洞尤其危险，因为从不可信来源加载的 ML 模型可以触发它们。Rust 防止所有三种情况：边界检查捕获溢出，类型系统强制形状一致性，显式 as 转换语义防止静默截断。

A.9 GPU 内存利用的乐趣与利益（USENIX Security 2024）

学术研究表明，CUDA 内核全局内存中的缓冲区溢出可被利用进行代码注入、GPU 上的返回导向编程，以及跨租户 ML 模型权重篡改。与 CPU 不同，GPU 内存空间缺乏 ASLR、栈金丝雀等标准保护。恶意 GPU 内核可以在共享 GPU 云部署中篡改其他租户的模型权重。Rust 的边界检查在安全代码中完全防止缓冲区溢出——正是本文所展示的攻击类别。

每个主要 GPU/NPU 厂商——NVIDIA、AMD、ARM、Qualcomm——都在其加速器驱动和工具链中发布过包含内存安全漏洞的版本。其中至少四个在野外被积极利用。漏洞类型——use-after-free、越界写入、缓冲区溢出、竞态条件——正是 Rust 的所有权模型、借用检查器和边界检查在编译期消除的类别。这就是 ascend-rs 的实际动机：不仅是更干净的代码，而是消除具有现实安全后果的漏洞。

附录 B：CVE 代码分析——漏洞 C++ 代码 vs 安全 Rust 缓解方案

本附录展示附录 A 中记录的 CVE 的实际（或重建的）漏洞 C/C++ 代码，配以 ascend-rs 风格的 Rust 代码，从结构上防止每类漏洞。

B.1 引用计数释放后 Use-After-Free（CVE-2023-51042，AMDGPU）

Linux AMDGPU 驱动在释放 fence 引用计数后仍解引用其指针。

漏洞 C 代码（来自 amdgpu_cs.c，修复前 2e54154）：

r = dma_fence_wait_timeout(fence, true, timeout);
dma_fence_put(fence);          // 引用释放——fence 可能已被释放
if (r < 0)
    return r;
if (r == 0)
    break;
if (fence->error)              // USE-AFTER-FREE：fence 已被释放
    return fence->error;

ascend-rs 缓解方案——Rust 所有权确保值被消费而非悬垂：

fn wait_all_fences(fences: &[Arc<Fence>], timeout: Duration) -> Result<()> {
    for fence in fences {
        let status = fence.wait_timeout(timeout)?;
        // 在仍持有 Arc 引用时检查 error
        if let Some(err) = fence.error() {
            return Err(err);
        }
        // Arc 引用在循环迭代结束前一直有效
        // Rust 编译器拒绝在 drop 后使用 fence 的任何代码
    }
    Ok(())
}

Rust 如何防止此漏洞：Arc<Fence> 是引用计数的。编译器确保你无法在 Arc 被释放后访问 fence.error()——借用检查器在编译期拒绝对已移动/释放值的任何引用。

B.2 未检查用户索引导致越界写入（CVE-2024-0090，NVIDIA）

NVIDIA GPU 驱动通过 ioctl 接受用户提供的索引，未进行边界检查。

漏洞 C 代码（根据 CVE 描述重建）：

struct gpu_resource_table {
    uint32_t entries[MAX_GPU_RESOURCES];
    uint32_t count;
};

static int nvidia_ioctl_set_resource(struct gpu_resource_table *table,
                                     struct user_resource_request *req)
{
    // 错误：未检查用户提供的索引
    table->entries[req->index] = req->value;   // 越界写入
    return 0;
}

ascend-rs 缓解方案——Rust 切片在类型层面强制边界检查：

struct GpuResourceTable {
    entries: Vec<u32>,
}

impl GpuResourceTable {
    fn set_resource(&mut self, index: usize, value: u32) -> Result<()> {
        *self.entries.get_mut(index)
            .ok_or(Error::IndexOutOfBounds)? = value;
        Ok(())
    }
}

Rust 如何防止此漏洞：Vec<u32> 跟踪自身长度。.get_mut() 对越界访问返回 None。在安全 Rust 中无法静默地写入缓冲区之外。

B.3 整数溢出导致堆缓冲区溢出（CVE-2024-53873，NVIDIA CUDA Toolkit）

CUDA cuobjdump 从伪造的 .cubin 文件读取 2 字节有符号值，符号扩展后用于 memcpy 大小。

漏洞 C 代码（来自 Talos 反汇编分析）：

int16_t name_len_raw = *(int16_t*)(section_data);  // 0xFFFF = -1
int32_t name_len = (int32_t)name_len_raw;           // 符号扩展为 -1
int32_t alloc_size = name_len + 1;                   // -1 + 1 = 0
memcpy(dest_buf, src, (size_t)alloc_size);           // 堆缓冲区溢出

ascend-rs 缓解方案——Rust 的检查算术捕获溢出：

fn parse_debug_section(section: &[u8], dest: &mut [u8]) -> Result<()> {
    let name_len_raw = i16::from_le_bytes(
        section.get(0..2).ok_or(Error::TruncatedInput)?.try_into()?
    );
    let alloc_size: usize = (name_len_raw as i32)
        .checked_add(1)
        .and_then(|n| usize::try_from(n).ok())
        .ok_or(Error::IntegerOverflow)?;

    let src = section.get(offset..offset + alloc_size)
        .ok_or(Error::BufferOverflow)?;
    dest.get_mut(..alloc_size)
        .ok_or(Error::BufferOverflow)?
        .copy_from_slice(src);
    Ok(())
}

Rust 如何防止此漏洞：checked_add() 在溢出时返回 None。usize::try_from() 拒绝负值。切片 .get() 对越界范围返回 None。

B.4 空容器越界读取（PyTorch Issue #37153）

PyTorch 的 CUDA 归约内核对标量张量的空 shape() 数组进行索引。

漏洞 C++ 代码（来自 Reduce.cuh）：

// iter.shape() 对标量输入返回空 IntArrayRef
int64_t dim0;
if (reduction_on_fastest_striding_dimension) {
    dim0 = iter.shape()[0];  // 越界：shape() 为空
    // dim0 = 垃圾值（如 94599111233572）
}

ascend-rs 缓解方案——Rust 的 Option 类型使空值显式化：

fn configure_reduce_kernel(shape: &[usize]) -> Result<KernelConfig> {
    let dim0 = shape.first()
        .copied()
        .ok_or(Error::ScalarTensorNotSupported)?;

    let (dim0, dim1) = match shape {
        [d0, d1, ..] => (*d0, *d1),
        [d0] => (*d0, 1),
        [] => return Err(Error::EmptyShape),
    };
    Ok(KernelConfig { dim0, dim1 })
}

Rust 如何防止此漏洞：shape.first() 返回 Option，强制调用者处理空值情况。match 对切片模式是穷举的——编译器要求 []（空）分支。

B.5 整数截断绕过边界检查（CVE-2019-16778，TensorFlow）

TensorFlow 的 UnsortedSegmentSum 内核将 int64 张量大小隐式截断为 int32。

漏洞 C++ 代码（来自 segment_reduction_ops.h）：

template <typename T, typename Index>  // Index = int32
struct UnsortedSegmentFunctor {
    void operator()(OpKernelContext* ctx,
                    const Index num_segments,  // 截断：int64 -> int32
                    const Index data_size,     // 截断：int64 -> int32
                    const T* data, /* ... */)
    {
        if (data_size == 0) return;  // 被绕过：截断值 != 0
        // data_size = 1（从 4294967297 截断）
    }
};

ascend-rs 缓解方案——Rust 类型系统拒绝隐式窄化：

fn unsorted_segment_sum(
    data: &DeviceBuffer<f32>,
    segment_ids: &DeviceBuffer<i32>,
    num_segments: usize,
) -> Result<DeviceBuffer<f32>> {
    let data_size: usize = data.len();

    let data_size_i32: i32 = i32::try_from(data_size)
        .map_err(|_| Error::TensorTooLarge {
            size: data_size,
            max: i32::MAX as usize,
        })?;
    // Rust 拒绝：let x: i32 = some_i64;  // 错误：类型不匹配
    Ok(output)
}

Rust 如何防止此漏洞：Rust 没有隐式整数窄化。let x: i32 = some_i64; 是编译错误。TryFrom/try_into() 在值不匹配时返回 Err。

B.6 锁释放后原始指针 Use-After-Free（CVE-2023-4211，ARM Mali）

ARM Mali GPU 驱动从共享状态复制原始指针，释放锁，休眠，然后解引用已悬垂的指针。

漏洞 C 代码（来自 mali_kbase_mem_linux.c，Project Zero 确认）：

static void kbasep_os_process_page_usage_drain(struct kbase_context *kctx)
{
    struct mm_struct *mm;
    spin_lock(&kctx->mm_update_lock);
    mm = rcu_dereference_protected(kctx->process_mm, /*...*/);
    rcu_assign_pointer(kctx->process_mm, NULL);
    spin_unlock(&kctx->mm_update_lock);  // 锁释放

    synchronize_rcu();  // 休眠——mm 可能被其他线程释放

    add_mm_counter(mm, MM_FILEPAGES, -pages);  // USE-AFTER-FREE
}

ascend-rs 缓解方案——Rust 的 Arc + Mutex 防止悬垂引用：

struct DeviceContext {
    process_mm: Mutex<Option<Arc<MmStruct>>>,
}

impl DeviceContext {
    fn drain_page_usage(&self) {
        let mm = {
            let mut guard = self.process_mm.lock().unwrap();
            guard.take()  // 设为 None，返回 Option<Arc<MmStruct>>
        };
        // 锁在此处释放（guard 被 drop）

        if let Some(mm) = mm {
            synchronize_rcu();
            // mm 仍然存活——Arc 保证了这一点
            mm.add_counter(MmCounter::FilePages, -pages);
        }
        // mm 在此处释放——Arc 引用计数递减
        // 仅在最后一个 Arc 引用被 drop 时才释放底层内存
    }
}

Rust 如何防止此漏洞：Arc<MmStruct> 是引用计数智能指针。从 Option 中取出后我们拥有一个强引用。即使锁释放后其他线程运行，我们的 Arc 保持 MmStruct 存活。在安全 Rust 中无法从 Arc 获得悬垂原始指针。

附录 C：300 个 MultiKernelBench 内核的漏洞分析

MultiKernelBench 的 300 个内核涵盖 15 个类别。如果按照标准 AscendC C++ 方式实现，每个内核都会继承 GM_ADDR/LocalTensor/FreeTensor API 的结构性漏洞模式。我们系统分类哪些模式影响哪些内核类别，统计暴露面，并展示最高风险的 C++ 与 ascend-rs 对比。

C.1 漏洞模式分布

漏洞模式	影响的内核类别	数量 (/300)	严重程度
V1：GM_ADDR 类型擦除	全部 15 个类别	300	高
V2：未检查的 `GetValue`/`SetValue` 越界	索引 (12)、卷积 (34)、池化 (6)、缩放 (10)、网络架构 (50)、注意力 (15)、数学 (6)	133	严重
V3：偏移计算整数溢出	所有多核内核：激活函数 (16)、广播 (10)、归约 (5)、归一化 (8)、融合算子 (100)、矩阵乘法 (17)、优化器 (5)	161	高
V4：FreeTensor 释放后使用	所有分块/流水线内核	300	高
V5：LocalTensor 双重释放	所有分块/流水线内核	300	中
V6：缺失 `pipe_barrier` 同步	所有 DMA+计算内核	300	严重

关键发现：每个 AscendC C++ 内核在结构上都暴露于 V1（类型擦除）、V4（释放后使用）、V5（双重释放）和 V6（缺失同步），因为这些是 API 本身的属性，而非特定算法的问题。算法性漏洞（V2、V3）影响的子集取决于内核是否使用逐元素索引访问或多核偏移算术。

C.2 最高风险类别：索引操作（12 个内核）

索引内核（gather、scatter、scatter_add、index_select、index_copy、index_add、embedding、masked_fill、inplace_update、take_along_dim、argmax、argmin）是最高风险类别，因为它们同时组合了全部六种漏洞模式：

V1：GM_ADDR 擦除张量元素类型
V2：用户提供的索引值无边界检查地访问任意偏移
V3：idx * row_len + j 对大张量可能溢出 uint32_t
V4/V5：分块实现使用 FreeTensor 生命周期管理
V6：需要 DMA 与计算之间的同步

C++ AscendC gather（存在漏洞）：

#include "kernel_operator.h"

// GM_ADDR 擦除所有类型信息——调用者可以传入任何数据类型
extern "C" __global__ __aicore__
void gather(GM_ADDR input, GM_ADDR index, GM_ADDR output, GM_ADDR len_buf) {
    uint32_t n = *((__gm__ uint32_t *)len_buf);
    // V1：从 GM_ADDR 手动转换——无编译期类型安全
    __gm__ float *in_ptr = (__gm__ float *)input;
    __gm__ uint32_t *idx_ptr = (__gm__ uint32_t *)index;
    __gm__ float *out_ptr = (__gm__ float *)output;

    for (uint32_t i = 0; i < n; i++) {
        uint32_t idx = idx_ptr[i];
        // V2：idx 无边界检查——攻击者控制的索引
        // 可读取 GM 地址空间内的任意内存
        out_ptr[i] = in_ptr[idx];  // 若 idx >= input_len 则越界
    }
}

ascend-rs gather（已缓解）：

#[ascend_std::aiv_kernel]
pub unsafe fn gather(
    input: *const f32,   // V1 已缓解：类型化指针，非 GM_ADDR
    index: *const u32,
    output: *mut f32,
    len: *const u32,
) {
    unsafe {
        let n = *len;
        let mut i = 0u32;
        loop {
            if i >= n { break; }  // 循环边界显式表达
            let idx = *index.wrapping_add(i as usize);
            // V2：wrapping_add 显式表达指针算术语义
            // V3：无整数溢出——每个偏移独立转换
            *output.wrapping_add(i as usize) = *input.wrapping_add(idx as usize);
            i = i + 1;
        }
        // V4/V5：无 FreeTensor——缓冲区 ID 自动管理
        // V6：无 DMA/计算分离——标量操作直接访问 GM
    }
}

C.3 高风险类别：卷积内核（34 个内核）

卷积内核具有深层嵌套循环和复杂的多维索引算术（oc * in_ch * k_h * k_w + ic * k_h * k_w + kh * k_w + kw）。索引表达式中的单个维度错误会静默读取错误内存。

C++ AscendC conv2d 索引计算（存在漏洞）：

// V2+V3：6层嵌套索引算术——极易弄错某个维度
for (int oc = 0; oc < out_ch; oc++) {
    for (int oh = 0; oh < out_h; oh++) {
        for (int ow = 0; ow < out_w; ow++) {
            float sum = 0.0f;
            for (int ic = 0; ic < in_ch; ic++) {
                for (int kh = 0; kh < k_h; kh++) {
                    for (int kw = 0; kw < k_w; kw++) {
                        int ih = oh * stride + kh * dilation;
                        int iw = ow * stride + kw * dilation;
                        // V3：32位乘法链可能溢出
                        int in_idx = ic * in_h * in_w + ih * in_w + iw;
                        int w_idx = oc * in_ch * k_h * k_w
                                  + ic * k_h * k_w + kh * k_w + kw;
                        // V2：无边界检查——若 ih >= in_h 或 iw >= in_w，
                        // 则从 GM 越界读取
                        sum += (float)inLocal.GetValue(in_idx)
                             * (float)wLocal.GetValue(w_idx);
                    }
                }
            }
            outLocal.SetValue(oc * out_h * out_w + oh * out_w + ow, sum);
        }
    }
}

ascend-rs conv2d（已缓解）：

#[ascend_std::aiv_kernel]
pub unsafe fn conv_standard_2d(
    input: *const f32, weight: *const f32, output: *mut f32,
    params: *const u32,  // [in_ch, out_ch, in_h, in_w, k_h, k_w, stride, dilation]
) {
    unsafe {
        // 所有参数从类型化指针读取——无 GM_ADDR 转换
        let in_ch = *params;
        let out_ch = *params.wrapping_add(1);
        // ...（读取其余参数）
        let out_h = (in_h - (k_h - 1) * dilation - 1) / stride + 1;
        let out_w = (in_w - (k_w - 1) * dilation - 1) / stride + 1;

        let mut oc = 0u32;
        loop {
            if oc >= out_ch { break; }
            // ...显式边界的嵌套循环...
            let ih = oh * stride + kh * dilation;
            let iw = ow * stride + kw * dilation;
            // V3 已缓解：通过 `as usize` 显式表达 wrapping 语义
            // 调试构建溢出时 panic，发布构建有意 wrapping
            let in_idx = (ic * in_h * in_w + ih * in_w + iw) as usize;
            let w_idx = (oc * in_ch * k_h * k_w
                       + ic * k_h * k_w + kh * k_w + kw) as usize;
            sum = sum + *input.wrapping_add(in_idx) * *weight.wrapping_add(w_idx);
            // V4/V5：无需 FreeTensor
            // V6：无 DMA——标量 GM 访问
        }
    }
}

C.4 高风险类别：融合算子（100 个内核）

融合内核（matmul+activation、conv+norm+activation 等）串联多个流水线阶段。在 C++ 中，每个阶段都需要各自的 AllocTensor/FreeTensor/pipe_barrier——遗漏任何一个都会产生静默数据损坏。

C++ 融合 matmul+sigmoid（存在漏洞）：

// 融合 matmul + sigmoid：C = sigmoid(A * B)
// V4：分配/释放 4 个张量——每个都是释放后使用的机会
// V5：融合变体之间的复制粘贴可能重复 FreeTensor
// V6：3 次流水线转换（DMA->cube, cube->vector, vector->DMA）
//     ——每次都需要 pipe_barrier，遗漏任何一个 = 读取过期数据

AscendC::LocalTensor<half> aLocal = inQueueA.AllocTensor<half>();
AscendC::DataCopy(aLocal, aGm, m * k);
inQueueA.EnQue(aLocal);
// V6：此处需要 DMA -> cube 的屏障
aLocal = inQueueA.DeQue<half>();

// ...矩阵乘法...

inQueueA.FreeTensor(aLocal);
// V4：aLocal 句柄仍然有效——意外读取能编译和运行

AscendC::LocalTensor<float> cLocal = outQueue.AllocTensor<float>();
// V6：此处需要 cube -> vector 的屏障
AscendC::Muls(cLocal, cLocal, -1.0f, total);  // sigmoid 步骤 1
AscendC::Exp(cLocal, cLocal, total);            // sigmoid 步骤 2
// V6：310P 上同缓冲区就地链式操作需要操作间屏障
AscendC::Adds(cLocal, cLocal, 1.0f, total);    // sigmoid 步骤 3
AscendC::Reciprocal(cLocal, cLocal, total);     // sigmoid 步骤 4
outQueue.FreeTensor(cLocal);

ascend-rs 融合 matmul+sigmoid（已缓解）：

#[ascend_std::aiv_kernel]
pub unsafe fn fused_matmul_sigmoid(
    a: *const u16, b: *const u16, c: *mut f32, dims: *const u32,
) {
    unsafe {
        let m = *dims;
        let k = *dims.wrapping_add(1);
        let n = *dims.wrapping_add(2);

        // V6 已缓解：matmul_f16 内部处理 DMA+cube
        ascend_std::kernel_ops::matmul_f16(c, a, b, m, k, n);
        ascend_std::ascend_pipe_barrier();  // 显式、可见

        let total = m * n;
        let buf_c = ascend_std::ascend_buf_alloc(total);
        ascend_std::ascend_buf_load_f32(buf_c, c as *const f32, total);
        ascend_std::ascend_pipe_barrier();  // 显式、可见

        // V6 已缓解：sigmoid_f32 包含所有内部屏障
        // (muls -> barrier -> exp -> barrier -> adds -> barrier -> reciprocal)
        ascend_std::kernel_ops::sigmoid_f32(buf_c, buf_c, total);

        ascend_std::ascend_pipe_barrier();  // 显式、可见
        ascend_std::ascend_buf_store_f32(c, buf_c, total);
        // V4/V5：无 FreeTensor——buf_c 自动管理
    }
}

C.6 ascend-rs 如何消除每种模式

模式	C++ 根因	ascend-rs 缓解	残余风险
V1：类型擦除	`GM_ADDR = uint8_t*` 用于所有张量	函数签名中的类型化 `const f32` / `const u16`	无（编译期）
V2：未检查越界	`GetValue(i)` / `SetValue(i,v)` 无边界检查	向量指令带显式计数 `n`；标量循环使用 `wrapping_add`	`unsafe` 指针算术运行时仍无检查
V3：整数溢出	`blockIdx * perBlockLen` 静默回绕	`wrapping_mul` 使溢出显式化；调试构建会 panic	开发者须选择 `wrapping_` 或 `checked_`
V4：释放后使用	`FreeTensor()` 使句柄失效，C++ 允许继续使用	无 `FreeTensor` API；缓冲区 ID 是类型化新类型（`UbBuf`、`L1Buf` 等），非拥有句柄	无（API 层面）
V5：双重释放	`FreeTensor()` 调用两次破坏空闲链表	无 `FreeTensor` API；缓冲区生命周期自动管理	无（API 层面）
V6：缺失同步	每次流水线转换需手动 `pipe_barrier()`	`kernel_ops` 组合算子包含所有内部屏障；DMA 屏障显式且数量少	开发者须放置 DMA<->计算屏障（每内核 2 个，非每操作）

净效果：在 300 个内核总共 1,633 个漏洞暴露中，ascend-rs 在 API/类型层面消除了 1,500 个（V1、V4、V5 完全消除；V6 从每操作减少到每内核）。剩余的 133 个越界暴露（V2）通过将逐元素访问替换为整向量操作来缓解，但标量回退内核中的 unsafe 指针算术仍需程序员负责。

附录 D：生态系统集成——工作流、演示与漏洞防护

Python 生态系统中的 NPU 编程工具（TileLang、PyTorch、Triton、PyPTO）通常直接调用 bisheng 编译器将 AscendC C++ 编译为 NPU 二进制文件。这条路径绕过了所有硬件级验证——编译器本身不检查同步屏障是否存在、缓冲区是否超出物理 SRAM、入口点注解是否正确。本附录展示 ascend_compile 如何作为集成中枢，为每个工具提供编译前验证，并用具体的代码示例说明它捕获的漏洞。

D.1 `ascend_compile` 集成中枢

ascend_compile 提供 4 种接口，适配不同的集成场景：

接口	形式	典型使用方
Rust API	`ascend_compile::compile()`	ascend-rs 内部
C ABI	`libascend_compile.so`（FFI 导出）	PyTorch 昇腾后端
CLI	`ascend-compile kernel.cpp --soc Ascend910B3`	脚本、CI 流水线
Python 封装	`ascend_compile.py`（ctypes 封装 C ABI）	TileLang、Triton、PyPTO

在调用 bisheng 编译器之前，ascend_compile 执行 3 项编译前验证检查：

检查 1：入口点检查 — 内核源码必须包含 __aicore__ 注解。缺少此注解的函数不会被编译为 NPU 设备代码。

检查 2：DMA/同步屏障检查 — 扫描 DataCopy、copy_gm_to_ubuf 等 DMA 模式，若存在 DMA 但无 pipe_barrier() / set_flag / wait_flag：

310P 目标：报错误（310P 无自动同步，缺少屏障必然导致挂起）
910B 目标：报警告（编译器自动同步可能处理，但显式屏障更安全）

检查 3：缓冲区大小检查 — 解析 InitBuffer 调用中的数值参数（支持 256 * 1024 等乘法表达式），对照目标硬件的实际统一缓冲区（UB）限制验证：

910B：192 KB（196,608 字节）
310P：256 KB（262,144 字节）

这 3 项检查均为轻量级字符串扫描，无需执行编译，为流水线增加不到 1ms 的开销。

D.2 TileLang 集成

工作流：TileLang 从 Python DSL 生成 AscendC C++ 源码 → 用 ascend_compile.compile_kernel() 替换裸露的 subprocess.run(bisheng, ...)，获得编译前验证。

演示：

from ascend_compile import compile_kernel

# TileLang 从 Python DSL 生成的 C++ 源码
kernel_source = '''
#include "kernel_operator.h"
extern "C" __global__ __aicore__ void tilelang_matmul(
    GM_ADDR a, GM_ADDR b, GM_ADDR c, GM_ADDR workspace) {
    AscendC::GlobalTensor<half> aGm;
    aGm.SetGlobalBuffer((__gm__ half*)a);
    // DMA 加载
    AscendC::DataCopy(aLocal, aGm, {1, 32, 0, 0});
    // 计算
    AscendC::Mmad(cLocal, aLocal, bLocal, 16, 16, 16);
    // DMA 存储
    AscendC::DataCopy(cGm, cLocal, {1, 32, 0, 0});
}
'''

# 带验证的编译 — 捕获缺失的 pipe_barrier！
try:
    binary = compile_kernel(
        kernel_source,
        soc="Ascend310P1",    # 310P 需要显式屏障
        shared=True,
        validate=True,
    )
except RuntimeError as e:
    print(f"捕获到: {e}")
    # "validation failed:
    #   error: line 8: DMA operations found but no pipe_barrier/sync
    #   — required on Ascend310P1"

漏洞：无 ascend_compile 时，TileLang 的裸露 subprocess.run(bisheng) 会成功编译此内核。在 310P 上，内核会静默挂起 — DMA 完成后计算单元从 UB 读取陈旧数据，因为 DMA 与计算之间没有 pipe_barrier(PIPE_ALL)。这是附录 C 的漏洞模式 V6（缺失同步）。ascend_compile 在编译期捕获此问题。

ascend-rs 缓解：ascend_compile 能检测缺失的屏障，而 ascend-rs 从根本上消除此漏洞类别。在更安全的工作流中，TileLang 的 Python DSL 生成 Rust 内核而非 C++ — ascend-rs 代码生成器随后产生带有构造保证屏障的 C++：

// Rust 内核：TileLang DSL → ascend-rs 而非原始 C++
#[ascend_std::aiv_kernel]
pub unsafe fn tilelang_softmax(input: *const f32, output: *mut f32, n_ptr: *const u32) {
    unsafe {
        let n = *n_ptr;
        let buf_in  = ascend_std::ascend_buf_alloc(n);
        let buf_out = ascend_std::ascend_buf_alloc(n);
        let work    = ascend_std::ascend_buf_alloc(n);

        ascend_std::ascend_buf_load_f32(buf_in, input, n);
        ascend_std::ascend_pipe_barrier();  // 代码生成器也会在 DMA 后自动插入

        // kernel_ops::softmax_f32 内含 4 个 pipe_barrier() 调用 —
        // 不可能遗忘其中任何一个
        ascend_std::kernel_ops::softmax_f32(buf_out, buf_in, work, n);

        ascend_std::ascend_pipe_barrier();  // 代码生成器也会在 DMA 前自动插入
        ascend_std::ascend_buf_store_f32(output, buf_out, n);
    }
}

kernel_ops::softmax_f32 组合算子展开为 ReduceMax → Adds → Exp → ReduceSum → Muls，每一步之间都有 pipe_barrier(PIPE_ALL)。此外，MLIR→C++ 代码生成器（mlir_to_cpp.rs）会在每次 DMA 加载之后和每次 DMA 存储之前自动插入 pipe_barrier(PIPE_ALL) — 即使程序员遗漏了显式调用，也提供第二层防护。结果：同步 Bug 在 ascend-rs 内核中结构性不可能发生，而不仅仅是被检测到。

D.3 PyTorch 集成

工作流：torch.compile 配合昇腾后端生成 AscendC C++ 内核 → 通过 C ABI（libascend_compile.so）或 Python 封装调用 ascend_compile，获得缓冲区大小验证。

演示：

import torch

# 第 1 步：定义使用自定义昇腾内核的模型
@torch.compile(backend="ascend")
def fused_gelu(x):
    return x * 0.5 * (1.0 + torch.tanh(
        0.7978845608 * (x + 0.044715 * x ** 3)))

# 第 2 步：昇腾后端生成 AscendC C++
from ascend_compile import compile_kernel

generated_cpp = '''
#include "kernel_operator.h"
extern "C" __global__ __aicore__ void gelu_kernel(
    GM_ADDR input, GM_ADDR output, GM_ADDR workspace) {
    AscendC::TPipe pipe;
    pipe.InitBuffer(inQueue, 1, 300000);  // 300KB > 910B 的 192KB UB 限制！
}
'''

try:
    binary = compile_kernel(generated_cpp, soc="Ascend910B3")
except RuntimeError as e:
    print(f"捕获到: {e}")
    # "validation failed:
    #   error: line 6: InitBuffer size 300000 bytes exceeds
    #   Ascend910B3 UB limit of 196608 bytes"

漏洞：无 ascend_compile 时，超出 NPU 统一缓冲区的缓冲区大小会正常编译，但在运行时引发硬件异常 — 内核写入超出物理 SRAM 边界，可能破坏其他核心的数据。这是 C++ 编译器无法捕获的硬件级缓冲区溢出。ascend_compile 对照目标实际 UB 限制验证 InitBuffer 大小。

ascend-rs 缓解：在更安全的工作流中，torch.compile 的昇腾后端生成 Rust 内核而非 C++。缓冲区管理通过 ascend_buf_alloc() 返回的类型化新类型 ID（UbBuf、L1Buf、L0aBuf 等）实现 — 非原始指针，非 FreeTensor 句柄。新类型防止混用不同存储层级的缓冲区（例如，将 L0aBuf 传递给 UB 向量操作会导致编译错误）。代码生成器将这些 ID 转换为 AscendC TBuf<TPosition::VECCALC> 对象，大小由内核数据流分析计算：

// Rust 内核：torch.compile → ascend-rs 而非原始 C++
#[ascend_std::aiv_kernel]
pub unsafe fn fused_gelu(input: *const f32, output: *mut f32, n_ptr: *const u32) {
    unsafe {
        let n = *n_ptr;
        // 类型化缓冲区 ID (UbBuf) — 无指针算术，无大小错误
        let buf = ascend_std::ascend_buf_alloc(n);
        let tmp = ascend_std::ascend_buf_alloc(n);
        let work = ascend_std::ascend_buf_alloc(n);

        ascend_std::ascend_buf_load_f32(buf, input, n);
        ascend_std::ascend_pipe_barrier();

        // 通过组合算子实现 GELU：x * sigmoid(1.702 * x)
        ascend_std::kernel_ops::gelu_f32(tmp, buf, work, n);

        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_buf_store_f32(output, tmp, n);
    }
}

代码生成器从内核的 ascend_buf_alloc(n) 调用和目标的 UB 限制确定 InitBuffer 大小 — 如果 n 个元素超出 UB 容量，可自动对计算进行分块。程序员无需手动计算缓冲区大小，也不会向 InitBuffer 传递原始字节数。结果：缓冲区溢出在设计上被消除，而不仅仅是被检测到。

D.4 Triton 集成

工作流：Triton IR → 昇腾后端降级为 AscendC C++ → ascend_compile 处理最终编译并验证入口点注解。

演示：

from ascend_compile import compile_kernel

# Triton 后端将 GPU 内核降级为 AscendC C++
# 但入口点注解错误（常见的 GPU→NPU 移植错误）
triton_generated = '''
extern "C" __global__ void vector_add(  // 缺少 __aicore__！
    GM_ADDR x, GM_ADDR y, GM_ADDR z, GM_ADDR workspace) {
    AscendC::GlobalTensor<float> xGm;
    xGm.SetGlobalBuffer((__gm__ float*)x);
}
'''

try:
    binary = compile_kernel(triton_generated, soc="Ascend910B3")
except RuntimeError as e:
    print(f"捕获到: {e}")
    # "validation failed:
    #   error: no __aicore__ entry point found"

漏洞：__aicore__ 属性指示编译器为 NPU 的 AI Core 生成代码，而非宿主机 CPU。缺少此属性时，bisheng 可能将函数编译为宿主机函数，或生成在 NPU 上启动时因调用约定和寄存器分配错误而崩溃的二进制文件。这是静默的、灾难性的故障：二进制文件存在、可加载，但计算出垃圾值或挂起。

ascend-rs 缓解：在更安全的工作流中，Triton-Ascend 后端将 Triton IR 降级为带有 #[aiv_kernel] 标注的 Rust 内核。代码生成器无条件地发出正确的 MLIR 属性（hacc.entry、hacc.function_kind = #hacc.function_kind<DEVICE>）和带有 __global__ 和 __aicore__ 的 C++ 入口点：

// Rust 内核：Triton IR → ascend-rs 而非原始 C++
#[ascend_std::aiv_kernel]  // ← 在代码生成器中触发自动 __aicore__
pub unsafe fn vector_add(
    x: *const f32, y: *const f32, z: *mut f32, n_ptr: *const u32,
) {
    unsafe {
        let n = *n_ptr;
        let bx = ascend_std::ascend_buf_alloc(n);
        let by = ascend_std::ascend_buf_alloc(n);

        ascend_std::ascend_buf_load_f32(bx, x, n);
        ascend_std::ascend_buf_load_f32(by, y, n);
        ascend_std::ascend_pipe_barrier();

        ascend_std::ascend_add_f32(bx, bx, by, n);

        ascend_std::ascend_pipe_barrier();
        ascend_std::ascend_buf_store_f32(z, bx, n);
    }
}

declare.rs 中的代码生成器检测到 #[aiv_kernel] 属性后无条件添加 MLIR 入口点属性。Rust 内核函数不存在不带 __aicore__ 注解即可编译的代码路径 — 该属性由编译器而非程序员施加。这将一个容易出现人为错误的注解任务转化为自动的、工具链保证的属性。

D.5 PyPTO 集成

工作流：PyPTO 的 PTO 虚拟指令集（约 90 条指令）编译为 AscendC C++ → ascend_compile 验证缓冲区分配并编译。

演示：

from ascend_compile import compile_kernel

# PyPTO 从 tile 级 Python 操作生成的 C++
pypto_generated = '''
#include "kernel_operator.h"
extern "C" __global__ __aicore__ void pypto_tile_op(
    GM_ADDR input, GM_ADDR output, GM_ADDR workspace) {
    AscendC::TPipe pipe;
    // PyPTO 为双缓冲 tile 分配了 512KB
    pipe.InitBuffer(inQueue, 2, 256 * 1024);  // 2 x 256KB = 512KB
    // 但 910B UB 总共只有 192KB！

    AscendC::LocalTensor<float> aLocal = inQueue.DeQue();
    AscendC::DataCopy(outputGm, aLocal, {1, 64, 0, 0});
    pipe_barrier(PIPE_ALL);
}
'''

try:
    binary = compile_kernel(pypto_generated, soc="Ascend910B3")
except RuntimeError as e:
    print(f"捕获到: {e}")
    # "validation failed:
    #   error: line 6: InitBuffer size 262144 bytes exceeds
    #   Ascend910B3 UB limit of 196608 bytes"

漏洞：PyPTO 的 tile 调度器优化吞吐量，可能分配超过目标物理 SRAM 的 tile。无目标感知验证时，编译出的内核会尝试使用超出实际存在的统一缓冲区，导致内核自身缓冲区之间或相邻 AI Core 上共驻内核之间的内存损坏。ascend_compile 能捕获此问题，因为它知道每个目标的确切 UB 大小（910B 为 192 KB、310P 为 256 KB）。

ascend-rs 缓解：在更安全的工作流中，PyPTO 的 tile 级操作映射为 ascend-rs kernel_ops 组合算子。缓冲区分配使用 ascend_buf_alloc(n) 以元素计数（非字节大小）— 代码生成器从元素计数和数据类型计算物理 InitBuffer 字节数，并在代码生成阶段对照目标的 UB 限制进行验证：

// Rust 内核：PyPTO tile 操作 → ascend-rs 而非原始 C++
#[ascend_std::aiv_kernel]
pub unsafe fn pypto_tile_matmul(
    a: *const u16, b: *const u16, c: *mut f32, n_ptr: *const u32,
) {
    unsafe {
        let n = *n_ptr;
        // 类型化缓冲区分配 — 代码生成器映射到带有正确 TPosition 的 TBuf
        let l1_a  = ascend_std::ascend_buf_alloc_l1(n);   // L1 缓冲区
        let l0a   = ascend_std::ascend_buf_alloc_l0a(n);  // L0A 缓冲区（Cube 输入 A）
        let l0b   = ascend_std::ascend_buf_alloc_l0b(n);  // L0B 缓冲区（Cube 输入 B）
        let l0c   = ascend_std::ascend_buf_alloc_l0c(n);  // L0C 缓冲区（Cube 输出）

        // 每个 alloc 在代码生成器中映射到特定的 TBuf<TPosition::*>
        // L0A → TBuf<TPosition::A1>，L0B → TBuf<TPosition::B1> 等
        // 混用位置在生成的 C++ 中是编译错误
        ascend_std::ascend_mmad_f16(l0c, l0a, l0b, n, n, n, 1);
    }
}

代码生成器为 L0A 发出 TBuf<TPosition::A1>，为 L0B 发出 TBuf<TPosition::B1>，为 L0C 发出 TBuf<TPosition::CO1> — AscendC 类型系统强制 L0A 缓冲区不能传递给 L0B 操作，反之亦然。结合基于元素计数（非原始字节数）的分配方式，缓冲区大小错误在代码生成阶段即被捕获，而非在硬件运行时。PyPTO 的 tile 调度器可以面向 ascend-rs 内核，确信缓冲区位置和大小约束由类型系统强制执行。

D.6 检测与结构性缓解对比

ascend_compile 检测 C++ 代码中的漏洞；ascend-rs 消除整个漏洞类别。下表对比两个层次的防御：

工具	漏洞	`ascend_compile` 检测	ascend-rs 结构性缓解
TileLang	V6：缺失同步屏障	310P 上 `DataCopy` 无 `pipe_barrier` 报错	`kernel_ops` 组合算子内嵌所有屏障；代码生成器自动插入 DMA 屏障
PyTorch	缓冲区大小溢出	`InitBuffer` > 目标 UB 限制报错	`ascend_buf_alloc(n)` 使用元素计数；代码生成器计算字节大小
Triton	缺少 `__aicore__` 入口	源码中未找到 `__aicore__` 报错	`#[aiv_kernel]` 在代码生成器中触发无条件的 `hacc.entry` 属性
PyPTO	缓冲区超出 UB 限制	`InitBuffer` > 目标 UB 限制报错	类型化 `TBuf<TPosition::*>` 位置；基于元素计数的分配

两个层次互为补充。ascend_compile 验证对任何 C++ 内核源码有效，无论其来源——目前即可保护整个生态系统。ascend-rs 缓解更进一步，使漏洞在通过其 Rust→MLIR→C++ 流水线编写的内核中结构性不可能发生。采用 ascend-rs 作为后端的工具将自动获得两个层次的防护。截至本文撰写时，ascend_compile 验证已可供集成使用；ascend-rs Rust 后端是一个架构选项，工具开发者可在未来版本中采用。

这 3 项验证检查是轻量级的（字符串扫描，无需编译），为编译流水线增加不到 1ms 的开销。在 NPU 上，挂起的内核不会产生栈跟踪、核心转储或错误信息 — 只有超时。ascend_compile 将这些不透明的运行时故障转化为带有行号和目标特定解释的可操作编译期错误。

D.7 PyTorch 金标准值测试

除了作为编译集成的下游消费者，PyTorch 还在 ascend-rs 的正确性验证中扮演金标准参考的角色。tests/kernel_correctness/golden/generate.py 使用 PyTorch 和 NumPy 为 6 个类别生成参考输出：

# tests/kernel_correctness/golden/generate.py
import torch
import torch.nn.functional as F

# 生成 conv2d 参考输出
torch.manual_seed(42)
x = torch.randn(1, 3, 7, 7)
w = torch.randn(8, 3, 3, 3)
y = F.conv2d(x, w, stride=1, padding=0)
# → conv_golden.json：由 `cargo test -p kernel_correctness` 加载使用

6 个类别的金标准值分布：

类别	JSON 文件	测试用例数
卷积	`conv_golden.json`	16
索引	`index_golden.json`	14
池化	`pooling_golden.json`	12
矩阵乘法	`matmul_golden.json`	13
缩放	`resize_golden.json`	8
杂项	`misc_golden.json`	9
总计		72

Rust 测试套件通过 cargo test -p kernel_correctness 加载这些 JSON 文件，将 Rust 内核的 CPU 模拟输出与 PyTorch 参考值逐元素对比，容差为 1e-5。

漏洞防护：通过将 Rust 内核输出与 PyTorch 参考值对比，在部署前捕获错误实现。例如，存在 off-by-one 索引错误（附录 C 的 V2：未检查越界）的 gather 内核会产生偏离 PyTorch 参考值的错误输出 — 金标准值测试能够在 CI 中自动捕获此类缺陷，无需访问实际 NPU 硬件。

— Deployable kernel

//! All 8+ benchmark kernels using the ascend-rs tile API.
//!
//! Each kernel compiles through ALL backends:
//! - `ACLRS_CODEGEN_PATH=pto`   → PTO-MLIR → ptoas → AscendC (Huawei Ascend 910B)
//! - `ACLRS_CODEGEN_PATH=nki`   → NKI Python → neuronx-cc (AWS Trainium3)
//! - `ACLRS_CODEGEN_PATH=gpu`   → CUDA kernels (NVIDIA GPU)
//! - `ACLRS_CODEGEN_PATH=musa`  → MUSA kernels (Moore Threads MTT S4000)
//! - `ACLRS_CODEGEN_PATH=spirv` → SPIR-V (Vulkan/Metal)
//! - `ACLRS_CODEGEN_PATH=aie`   → AIE2P (AMD Ryzen AI)
//! - `ACLRS_CODEGEN_PATH=bang`  → BANG-C (Cambricon MLU370/590)
//! - `ACLRS_CODEGEN_PATH=gaudi` → TPC-C (Intel Gaudi2/3)
//!
//! The tile API is the single Rust source that generates kernels for all targets.
//!
//! All kernels are written against the safe `GmView` API: each `extern "C"`
//! entry point lifts its raw pointer args into shape-annotated views via a
//! `GmDeviceCtx`, then runs in safe code. The op calls go through the
//! `safe::` module which provides no-op safe wrappers around the underlying
//! `#[inline(always)]` intrinsics.

H.3 反例输入

对每个安全类别，给出一个能在 C++ 中触发该漏洞、但在 Rust 中被捕获/阻止的反例输入。

Class 1: 类型混淆

触发条件： 将 f16 数据传入 f32 kernel

C++ 行为： 静默的数据损坏（将 f16 比特解释为 f32）

Rust 行为： 编译期类型错误（*const u16 ≠ *const f32）

示例 kernel： foreach_exp_f32

证据： 使用 GM_ADDR（已被类型擦除的 uint8_t*）

Class 2: 缓冲区越界

触发条件： count = buffer_size + 1

C++ 行为： 越界的 SRAM 读/写（未定义行为）

Rust 行为： 缓冲区 ID 抽象禁止裸索引

示例 kernel： foreach_dropout_f32

证据： 使用 GetValue（未检查的索引）+ 数组下标

Class 3: 释放后使用 (Use-After-Free)

触发条件： 释放缓冲区后再通过失效句柄读取

C++ 行为： 读取已释放的 SRAM（垃圾数据）

Rust 行为： 不存在 free API —— 缓冲区生命周期由运行时管理

示例 kernel： foreach_dropout_f32

证据： 调用 FreeTensor() —— 句柄仍然保留

Class 4: 同步缺失

触发条件： 在 load 与 compute 之间移除屏障

C++ 行为： 读到陈旧/不完整的 DMA 数据（非确定性）

Rust 行为： 始终在各阶段之间发出 ascend_pipe_barrier()

示例 kernel： foreach_add_list_f32

证据： 共有 2 处屏障 —— 缺一即出现数据竞争

Class 5: 重复释放 (Double Free)

触发条件： 对同一个 LocalTensor 两次调用 FreeTensor

C++ 行为： 损坏队列空闲链表（未定义行为）

Rust 行为： 不存在 free API —— 不可能 double-free

示例 kernel： foreach_dropout_f32

证据： FreeTensor 共被调用 54 次

Class 6: 整型溢出

触发条件： blockIdx=1048576, perBlockLen=4096 → 回绕到 0

C++ 行为： 静默回绕至 0，得到错误的内存偏移

Rust 行为： wrapping_mul(4096) → 0（显式语义，debug 模式下 panic）

示例 kernel： foreach_dropout_f32

证据： 使用 block 索引计算偏移

附录 I:性能差异分析

对 998 个 CANN 8.5 kernel 往返性能模式的分析。

ascend-rs 编译流水线 (Rust → MLIR → C++ → bisheng) 相比手写 AscendC C++ 会引入一些特定的代码生成模式。本附录识别这些模式,对其影响进行分级, 并提出可复用的优化方案。

I.1 性能分级

分级	数量	%	描述
EQUIVALENT	121	12%	生成代码与原始 C++ 性能相当
SLOW_1.2X	0	0%	因中等影响模式导致约 20% 变慢
SLOW_1.5X	0	0%	因高影响模式 (TBuf、barrier) 导致约 50% 变慢
SLOW_2X+	0	0%	因多个高影响模式叠加导致 2 倍以上变慢

I.2 性能劣化模式

使用 TBuf 而非 TQue (高)

受影响 kernel: 998/998

问题: 使用 TBuf<VECCALC> 而非 TQue<VECIN/VECOUT>。TBuf 在每个同步点都需要显式的 pipe_barrier(PIPE_ALL),而 TQue 通过硬件 flag 实现细粒度的 pipe 重叠。

修复方案: 生成带 AllocTensor/FreeTensor 生命周期的 TQue<QuePosition::VECIN, depth>,取代 TBuf.Get/TBuf.Get 模式。

PIPE_ALL barrier (整流水线停顿) (高)

受影响 kernel: 998/998

问题: 每次 ascend_pipe_barrier() 都会生成 pipe_barrier(PIPE_ALL),从而同时停顿所有硬件 pipe。原始 C++ 通过 TQue 或有选择的 PIPE_V/PIPE_MTE2 flag 做按 pipe 同步。

修复方案: 用 pipe_barrier(PIPE_V) 做仅计算的同步,用 PIPE_MTE2 做 DMA 同步,或者通过 TQue 完全消除 barrier。

无双缓冲 (高)

受影响 kernel: 998/998

问题: DMA 与计算完全串行化:load→barrier→compute→barrier→store。原始 C++ 通过 TQue depth=2 把第 N+1 个 tile 的 DMA 与第 N 个 tile 的计算重叠。

修复方案: 检测分块循环并生成 depth=2 的 TQue。通过 EnQue/DeQue 在 tile 之间实现 DMA 与计算重叠。

统一最大缓冲区尺寸 (低)

受影响 kernel: 998/998

问题: 所有 TBuf 都被分配相同的最大尺寸 = (UB_SIZE - 8KB) / num_bufs。原始 C++ 会按每个缓冲区的实际数据需求分配大小。当缓冲区使用差异较大时,这会浪费 UB 空间。

修复方案: 在 MLIR 中追踪实际缓冲区使用量,并按比例分配。

标量数学的矢量化变通方案 (中)

受影响 kernel: 1/998

问题: 由于某些 NPU 型号上标量 pipe 会挂死,标量 log/exp/sqrt 操作通过 1KB 临时缓冲区被矢量化。这给每次标量数学操作增加了 DMA 和缓冲区开销。

修复方案: 在支持的型号上使用标量 pipe;在其他型号上,通过批量化标量操作来摊销开销。

I.3 优化机会

barrier 消除机会 (中)

适用 kernel: 998/998

描述: 作用在不同缓冲区上的连续矢量操作之间不需要 barrier。当前 codegen 只要 dirty_bufs 重叠就插入 barrier,但许多操作其实彼此独立。

实现: 在 MLIR 层面实现按缓冲区的 dirty 追踪。仅当同一缓冲区上存在 RAW 冒险 (read-after-write hazard) 时才插入 barrier。

循环展开候选 (低)

适用 kernel: 998/998

描述: 小的固定迭代次数循环 (例如 softmax 的两遍 reduce) 可以展开。当前 codegen 发射的是通用的 while(true) 循环。

实现: 检测已知小迭代次数的循环并将其展开。

算子融合候选 (中)

适用 kernel: 0/998

描述: 作用在同一缓冲区上的连续矢量操作 (例如 Sub→Exp 或 Div→Cast) 可以融合为一条矢量指令,或者至少共享一个 barrier。当前 codegen 把它们各自当作独立操作。

实现: 检测在同一缓冲区上的一元/二元操作链,并将其融合为复合 AscendC 指令。

I.4 可复用的优化计划

基于上述模式分析,三项优化就能为大多数 kernel 弥合性能差距:

优先级 1:TQue 迁移 (约弥合差距的 50%)

在 MLIR→C++ codegen 中将 TBuf<VECCALC> 替换为 TQue<VECIN/VECOUT>。这样会用基于硬件 flag 的同步替代 PIPE_ALL barrier,并启用双缓冲实现 DMA 与计算重叠。

受影响文件: crates/rustc_codegen_mlir/src/mlir_to_cpp.rs

所需改动:

把缓冲区声明从 TBuf<TPosition::VECCALC> 改为 TQue<QuePosition::VECIN> / TQue<QuePosition::VECOUT>
用 inQueue.AllocTensor<T>() / inQueue.DeQue<T>() 替代 tbuf.Get<T>()
加入 inQueue.EnQue(tensor) / outQueue.FreeTensor(tensor) 生命周期
用隐式 TQue 同步替代 pipe_barrier(PIPE_ALL)

优先级 2:barrier 消除 (约弥合差距的 20%)

实现按缓冲区的 dirty 追踪,以消除独立矢量操作之间的 barrier。只有当同一缓冲区上存在 RAW 冒险 (read-after-write hazard) 时才插入 barrier。

当前行为: 任何读取 dirty 缓冲区的矢量操作都会触发 PIPE_ALL。

建议行为: 按缓冲区追踪 dirty 状态。只在以下情况插入 barrier:

DMA load 写入缓冲区 B,随后矢量操作读取缓冲区 B
矢量操作写入缓冲区 B,随后 DMA store 读取缓冲区 B
当 buf0 不是 dirty 时,跳过 Add(buf0, buf1, buf2) 与 Mul(buf3, buf0, buf4) 之间的 barrier

优先级 3:算子融合 (约弥合差距的 10%)

把同一缓冲区上的连续矢量操作融合为复合操作:

Sub(buf, x, max) → Exp(buf, buf) → 单次 AscendC 调用同时完成 Sub+Exp
Muls(buf, buf, scale) → Adds(buf, buf, bias) → MulAdd 复合操作
消除融合操作之间的中间 barrier

示例一：Hello World — ACL 设备初始化

最简单的 ascend-rs 程序：初始化 ACL 运行时、打开设备、创建上下文与流、打印设备描述符后退出。这一步验证驱动、CANN 和 Rust 工具链能否协同工作。

源代码

examples/acl_hello_world/src/main.rs：

use anyhow::Result;
use ascend_rs::prelude::*;
use log::info;
use simple_logger::SimpleLogger;

fn main() -> Result<()> {
    SimpleLogger::new().env().init().ok();

    // 每个 RAII 包装器在构造时申请资源，在 drop 时自动释放。
    // 编译器强制执行正确的生命周期嵌套：Device < AclContext < AclStream。
    let acl     = Acl::new()?;
    let device  = Device::new(&acl)?;
    let context = AclContext::new(&device)?;
    let stream  = AclStream::new(&context)?;

    info!("设备 {} 初始化成功", device.descriptor());
    info!("Context 句柄：{:p}", context.as_ptr());
    info!("Stream  句柄：{:p}", stream.as_ptr());

    // 变量离开作用域时，资源按逆序自动释放。
    Ok(())
}

编译流水线原理

每个编译步骤的中间文件保存在 kernels/target/ 中，可供检查：

kernels/target/davinci-huawei-none/release/deps/
├── softmax_kernels.mlir              ← rustc codegen 输出的 MLIR
├── softmax_kernels.mlir.acl.gen.cpp  ← mlir_to_cpp 生成的 C++
└── softmax_kernels.acl.o             ← bisheng 生成的 NPU 目标文件

生成的 C++（acl.gen.cpp）展示了 Rust 本征函数对应的 AscendC API 调用：

// 由 ascend_std::ascend_exp_f32(out_buf, out_buf, n) 生成
Exp(out_buf_local, out_buf_local, n);
pipe_barrier(PIPE_V);

示例三：Tile Softmax — 昇腾 910B 上的 PTO 编译路径

本示例演示较新的 PTO（可编程 Tile 操作） 编译路径，面向昇腾 910B（dav-c220）矩阵流水线。Tile API 以 tile_load、tile_softmax、tile_store 等二维 Tile 操作来表达计算，通过 ptoas（PTO 汇编器）编译，而非标准 C++ 编译路径。

这是三个示例中最先进的一个，需要配备 ptoas 的昇腾 910B 设备。它展示了完整流水线：

Rust Tile API  →  MLIR  →  PTO-MLIR  →  ptoas  →  CCE C++  →  ccec  →  .acl.o

在示例三基础上扩展为单次启动处理两个 tile，使用 tile_prefetch_f32 使 Mte2 加载（tile 1）与 Vector 计算（tile 0 softmax）形成重叠。性能数据见第 4.7 节。

生成的 PTO-MLIR

与示例三的关键区别在于：两次加载会生成具有不同行偏移的 partition_view 操作：

// tile 0：从第 0 行加载
%pto1 = pto.partition_view %pto0, offsets = [%c0, %c0], sizes = [%c1, %c1024] : ...
pto.tload ins(%pto1 : ...) outs(%pto2 : ...)

// tile 1：从第 1 行加载（偏移 1024 个元素 = cols=1024 时的第 1 行）

示例五：Linalg 桥的 Softmax — 上游 MLIR 跑在 910B2 上

本示例把同一份 softmax 内核走一遍 linalg ingress 桥，跑在真实的 910B2 硬件上。Rust 前端完全没用；源码是上游 MLIR 中的两行 linalg.softmax op，正是上游 MLIR 测试套件里能找到、或从 torch-mlir FX export 中抽出的那种 fixture。背景见第 4.7 节。

源码

完整 fixture 是两行上游 linalg：

// benchmarks/linalg/kernels_upstream_shape_matched/softmax_upstream_1x1024.mlir
func.func @upstream_softmax_1x1024(%arg0: tensor<1x1024xf32>) -> tensor<1x1024xf32> {
  %0 = tensor.empty() : tensor<1x1024xf32>
  %1 = linalg.softmax dimension(1) ins(%arg0 : tensor<1x1024xf32>)
                                   outs(%0   : tensor<1x1024xf32>) -> tensor<1x1024xf32>
  return %1 : tensor<1x1024xf32>
}

torch-mlir 从一个 4 行 PyTorch 脚本（adablue 上 /tmp/torch_mlir_linalg/dump_simple.py）export 出的等价形大体相同——见 benchmarks/linalg/kernels_torch_mlir_shape_matched/ 中的 add_tm.mlir、exp_tm.mlir、silumul_tm.mlir。所用的 torch-mlir wheel（torch-mlir-20260421.789）没有直接 export linalg.softmax；它降为一组 linalg.generic 归约序列，被桥通过 commit 299de147 加入的 GenericUnaryKind::Exp + GenericBinop matcher 处理。

构建与运行

  ascendrs : min= 1586.1 µs  upstream: min= 1586.4 µs  Δ= 0.3 µs   PASS  (<0.02%)

字节相同性证明

「字节相同 emit」是核心声明。证明它的纯宿主测试：

$ cargo test -p mlir_to_cpp_tests --release \
    --test upstream_matches_ascendrs_byte_identical -- --nocapture
running 5 tests
test add_1x1024_byte_identical          ... ok
test exp_1x1024_byte_identical          ... ok
test softmax_1x1024_byte_identical      ... ok
test matmul_32x64x32_byte_identical     ... ok
test silumul_1x1024_byte_identical      ... ok  （CPU 侧；今日尚不能在 910B2 上跑）
5 passed; 0 failed

每个 test 在 kernels_ascendrs/<name>.mlir（手写 ascendrs-form）与 kernels_upstream_shape_matched/<name>_upstream.mlir（上游 linalg）上都跑一次 linalg_to_ascendc，再字节比对生成的 .cce。零 diff 字节意味着桥在 hop 1 之后是结构性的 no-op；下游 mlir_to_cpp emitter 看不出任何区别。

两条分支在 mlir_to_cpp 处汇合。从那一点之后，硬件看到的字节与内核出发自哪条分支无关。

示例六：Softmax 上的安全卫士 — ptoas 说 OK，卫士说不

前面五个示例展示的内核都能跑。本示例展示一个看似能跑——通过 ptoas、ccec、bisheng——但悄悄输出错误结果的内核，并展示卫士抓住它的过程。章节讨论见 §11.3；本节是可运行 demo。

两份 fixture，同一编译器

两份 fixture 都是 1×1024 f32 softmax 的 PTO-MLIR .acl.pto。「good」是 mlir_to_pto 从示例五的上游 linalg fixture（或等价地从示例三的 Rust tile API 内核）emit 出的内容；「bad」是同一份文件，在归约序列前注入了 48 个额外 pto.alloc_tile + pto.tload——每个 tile 都是 1×1024 f32，没有任何下游读取，而 ptoas 的 PlanMemoryPass 把它们里的几个堆到了与活 tile %3 和 %11 同样的 UB offset。

# 生成两份 fixture
cd /home/y00577373/ascend-rs-priv
python3 blog/mdbook/scripts/ch11_make_bad_softmax.py /tmp/ch11_sm_bad.acl.pto

# good 文件已提交
cp examples/tile_softmax/artifacts/tile_softmax_kernels.acl.pto /tmp/ch11_sm_good.acl.pto

两份都过 ptoas

PTOAS=/usr/local/bin/ptoas-bin/ptoas   # adablue 上为 $HOME/ptoas-x86/bin/ptoas

$PTOAS /tmp/ch11_sm_good.acl.pto -o /tmp/good.cpp
echo "good rc=$?"
$PTOAS /tmp/ch11_sm_bad.acl.pto  -o /tmp/bad.cpp
echo "bad  rc=$?"

good rc=0
bad  rc=0

ptoas 都接受。ccec 都接受。bisheng 都链接得了。在 910B2 上，「good」内核给出 max_err=1.86e-9；「bad」内核给出每次都不同的垃圾——取决于死 tile 这一次踩到了哪些字节。

两份都过卫士

PTO_DIFF=/data/yuyijun/ascend-rs/target/release/pto-diff   # 或本地构建

$PTO_DIFF --from-pto /tmp/ch11_sm_good.acl.pto --ptoas $PTOAS
$PTO_DIFF --from-pto /tmp/ch11_sm_bad.acl.pto  --ptoas $PTOAS

=== /tmp/ch11_sm_good.acl.pto ===
0 errors, 0 warnings  (clean)

=== /tmp/ch11_sm_bad.acl.pto ===

... (94 more findings) ...

退出码：bad fixture 是 3，good 是 0。同一个 pto-diff 二进制、底下同一个 ptoas——两种结果的唯一区别是卫士以 ptoas 不会的方式审视 PlanMemoryPass 之后的 MLIR。

一键 demo 脚本

两次运行打包在 blog/mdbook/scripts/ch11_bad_demo.sh，也是 §11.6 demo 录制的驱动脚本。本地复现：

PTOAS=/usr/local/bin/ptoas-bin/ptoas \
PTO_DIFF=/data/yuyijun/ascend-rs/target/release/pto-diff \
  bash blog/mdbook/scripts/ch11_bad_demo.sh

在 linalg ingress 路径上的同等对比

为完整起见，下面是一段端到端 demo，从上游 linalg 出发（而非手编 PTO），同时演练 Path A（投影器）和 Path C（完整 ptoas 流水线）：

BIN=crates/mlir_to_cpp_tests/target/release/linalg_to_ascendc
SM=benchmarks/linalg/kernels_upstream_shape_matched/softmax_upstream_1x1024.mlir
ADV=benchmarks/linalg/kernels_adversarial/capacity_overflow_1x131072.mlir

echo "--- 干净 softmax via Path A ---"
ACLRS_LINALG_SAFETY=path-a $BIN $SM /tmp/clean.cce 2>&1 \
  | grep linalg-safety || echo "(clean — no findings)"

echo "--- 对抗 fixture via Path A ---"
ACLRS_LINALG_SAFETY=path-a $BIN $ADV /tmp/adv.cce 2>&1 \
  | grep linalg-safety || echo "(clean)"

echo "--- 对抗 fixture via Path C ---"
ACLRS_PTOAS_BIN=$HOME/ptoas-x86/bin/ptoas \
ACLRS_LINALG_SAFETY=path-c $BIN $ADV /tmp/adv.cce 2>&1 \
  | grep linalg-safety || echo "(clean)"

--- 干净 softmax via Path A ---
(clean — no findings)
--- 对抗 fixture via Path A ---
linalg-safety [path-a] [error] capacity: vec high-water 1048576 B exceeds capacity 196608 B
  (on Ascend910B2 (CANN 8.5)) (in `adv_capacity_overflow`)
--- 对抗 fixture via Path C ---
linalg-safety [path-c] [error] ptoas: vec overflow, requires 8388608 bits while 1572864 bits avaliable
  (in `adv_capacity_overflow`)

两条 Path 在同一份输入上都抓到了 capacity bug，机制不同——这正是给桥配两道互补安全面的全部理由。

常见问题排查

`Device startup failed`

NPU 驱动未运行或设备处于故障状态。请检查：

npu-smi info          # 查看 Health 是否为 OK（而非 Critical）
npu-smi reset -i 0    # 重置设备 0（需要 root 权限）

`Could not determine ASCEND_HOME_PATH`

ACLRS_CANN_PATH 未设置或路径不存在：

export ACLRS_CANN_PATH=/usr/local/Ascend/cann-8.5.0
# 验证路径是否存在：
ls $ACLRS_CANN_PATH/tools/ccec_compiler/bin/bisheng

`ptoas assembler not found`

将 ACLRS_PTOAS_PATH 设置为 ptoas 二进制文件的完整路径：

export ACLRS_PTOAS_PATH=/path/to/ptoas/build/tools/ptoas/ptoas

ptoas 是 pto-isa 项目的组成部分，仅 PTO 编译路径（示例三）需要。

`ccec PTO compilation failed: set_mask_count does not support target feature`

使用了错误的 --cce-aicore-arch。请确认：

ACLRS_SOC_VERSION 与你的芯片匹配
ascend-rs 位于 claude_code 或 main 分支（修复已提交至 d45ab4e3 和 adbf7294）

`error: definition of type 'bfloat16_t' conflicts with typedef`

你的 ccec 版本已定义 bfloat16_t。此问题已在提交 adbf7294 中修复。请更新到最新分支。

正确性检查失败（`max_err > 1e-5`）

310P 上的向量 softmax：期望 max_err < 1e-8（硬件 f32 精度）
910B 上的 tile softmax：期望 max_err < 1e-5（PTO 规约精度）
超出此范围可能说明 SoC 版本设置错误，导致 UB 缓冲区大小假设不匹配

总览：三条编译路径对比

示例一：Hello World
  Rust 宿主代码  →  cargo build  →  可执行文件  →  ACL 运行时  →  NPU 设备
  （无内核——纯宿主/驱动交互）

示例二：向量 Softmax（mlir_to_cpp 路径）
  Rust 内核  →  rustc  →  MLIR  →  mlir_to_cpp  →  AscendC C++
             →  bisheng  →  .acl.o  →  KernelLoader  →  NPU 执行

示例三：Tile Softmax（PTO 路径）
  Rust 内核  →  rustc  →  MLIR  →  mlir_to_pto  →  PTO-MLIR 方言
             →  ptoas  →  CCE C++  →  ccec  →  .acl.o
             →  KernelLoader  →  NPU 执行

三条路径共享同一套宿主端运行时（ascend_rs::prelude::*）：Acl、Device、AclContext、AclStream、DeviceBuffer、KernelLoader。唯一的区别在于 .acl.o 内核二进制文件的生成方式。
