概述
本文在qemu-riscv64平台上，利用向量扩展指令加速运行基于llama.cpp构建的大模型。

llama.cpp工程
Llama.cpp是一个基于C++编写的高性能大模型推理框架，旨在提供快速、稳定且易于使用的计算工具，Llama.cpp支持多种计算模式，包括向量计算、矩阵运算、图算法等，可广泛应用于机器学习、图像处理、数据分析等领域。
目录结构
src是构建模型架构的基础库文件夹
examples是部分案例模型的源文件
ggml是计算操作的库文件

起初移植代码在ggml.c中后续迁移至ggml-quants.c文件中。
修改函数包括12个：
quantize_row_q8_0
quantize_row_q8_1
ggml_vec_dot_q4_0_q8_0
ggml_vec_dot_q4_1_q8_1
ggml_vec_dot_q5_0_q8_0

ggml_vec_dot_q8_0_q8_0
ggml_vec_dot_q2_K_q8_K
ggml_vec_dot_q3_K_q8_K
ggml_vec_dot_q4_K_q8_K
ggml_vec_dot_q5_K_q8_K
ggml_vec_dot_q6_K_q8_K
这些函数作为不同量化模式的成员函数:
static const ggml_type_traits_t type_traits[GGML_TYPE_COUNT] = {[GGML_TYPE_Q8_0] = {.type_name = "q8_0",.blck_size = QK8_0,.type_size = sizeof(block_q8_0),.is_quantized = true,.to_float = (ggml_to_float_t) dequantize_row_q8_0,.from_float = quantize_row_q8_0,.from_float_ref = (ggml_from_float_t) quantize_row_q8_0_ref,.from_float_to_mat = quantize_mat_q8_0,.vec_dot = ggml_vec_dot_q8_0_q8_0,.vec_dot_type = GGML_TYPE_Q8_0,......
}
在ggml不同算子计算函数中被调用：
static void ggml_compute_forward_mul_mat_one_chunk(...)ggml_vec_dot_t const vec_dot = type_traits[type].vec_dot;for (int64_t iir1 = ir1_start; iir1 < ir1_end; iir1 += blck_1) {for (int64_t iir0 = ir0_start; iir0 < ir0_end; iir0 += blck_0) {for (int64_t ir1 = iir1; ir1 < iir1 + blck_1 && ir1 < ir1_end; ir1 += num_rows_per_vec_dot) {...for (int64_t ir0 = iir0; ir0 < iir0 + blck_0 && ir0 < ir0_end; ir0 += num_rows_per_vec_dot) {vec_dot(ne00, &tmp[ir0 - iir0], (num_rows_per_vec_dot > 1 ? 16 : 0), src0_row + ir0 * nb01, (num_rows_per_vec_dot > 1 ? nb01 : 0), src1_col, (num_rows_per_vec_dot > 1 ? src1_col_stride : 0), num_rows_per_vec_dot);}...}}}
2024/10/02: 工具准备OK，但qemu运行时被killed
工具版本
Qemu：
Gcc版本：
Github Release
llama.cpp：
llama.cpp Github 10月2号pull
llama-7b模型版本：
Huggingface gguf文件
编译
llama.cpp编译
cd llama.cpp
make RISCV_CROSS_COMPILE=1
运行命令

问题
命令运行现象
可能原因
运行内存可能太小
2024/10/03: 使用10xE团队的最新版，解决tokenizer的问题，但还是被killed
最新版Github链接
Tameem-10xE/llama.cpp Github
问题：运行7B模型被killed
运行现象
可能原因
有可能跟qemu运行的swapfile有关
可以团队成员提的一个issue：
Github Issue： qemu-riscv64 unexpectedly reached EOF error
解决办法
先尝试换一个更小的模型试试，不行就解决swapfile的问题
运行3B规模的model的现象：failed to allocate buffer of size

2024/10/05：生成非向量支持的riscv版本llama.cpp，进行对比实验
llama.cpp编译
make CC="riscv64-unknown-linux-gnu-gcc -march=rv64gc -mabi=lp64d" CXX="riscv64-unknown-linux-gnu-g++ -march=rv64gc -mabi=lp64d"
make CC="riscv64-unknown-linux-gnu-gcc -march=rv64gc -mabi=lp64d" CXX="riscv64-unknown-linux-gnu-g++ -march=rv64gc -mabi=lp64d"
报错：riscv64-unknown-linux-gnu-g++: error: ‘-march=native’: ISA string must begin with rv32 or rv64
解决方案：
GCC GitHub：riscv64-unknown-linux-gnu-g++: error: ‘-march=native’: ISA string must begin with rv32 or rv64
即将llama.cpp工程中的Makefile中523和524行修改为rv64gc编译，该部分原先是交叉编译时使能RVV编译，如图所示：
修正后编译命令
make RISCV_CROSS_COMPILE=1
运行结果
