RuyiSDK 性能测试示例

本示例在 PC 上使用 RuyiSDK GCC 和 LLVM 工具链交叉编译 Coremark，再将二进制文件传输到开发板运行。

安装ruyi包管理器（其他安装方式见官方安装文档）

sudo apt update; sudo apt install -y wget tar zstd xz-utils git build-essential
 
wget https://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.51.0/ruyi-0.51.0.amd64
chmod +x ./ruyi-0.51.0.amd64
sudo cp -v ./ruyi-0.51.0.amd64 /usr/local/bin/ruyi

安装GCC和LLVM工具链

ruyi update
ruyi install gnu-ruyisdk llvm-ruyisdk

Coremark（GCC版）

创建并激活ruyi虚拟环境（GCC）

ruyi venv -t gnu-ruyisdk generic gcc-env
. gcc-env/bin/ruyi-activate

验证GCC版本

riscv64-ruyisdk-linux-gnu-gcc -v

编译Coremark（GCC）

git clone https://github.com/eembc/coremark
cd coremark
make CC=riscv64-ruyisdk-linux-gnu-gcc XCFLAGS="-static -march=rv64imafd" compile
mv coremark.exe coremark-gcc
riscv64-ruyisdk-linux-gnu-objcopy --remove-section=.riscv.attributes coremark-gcc coremark-gcc

PC端传输

python3 -m http.server 8000

在开发板的minicom终端里运行：

wget http://10.13.61.37:8000/coremark-gcc -O /root/coremark-gcc
chmod +x /root/coremark-gcc
/root/coremark-gcc

输出结果

2K performance run parameters for coremark.
CoreMark Size    : 666
Total ticks      : 15336
Total time (secs): 15.336000
Iterations/Sec   : 1956.181534

退出ruyi GCC虚拟环境

cd ..; ruyi-deactivate

Coremark（LLVM版）

创建并激活ruyi虚拟环境（LLVM）

ruyi venv -t llvm-ruyisdk generic --sysroot-from gnu-ruyisdk llvm-env
. llvm-env/bin/ruyi-activate

验证LLVM版本

clang -v

编译Coremark（LLVM）

cd coremark
make clean
make CC=clang XCFLAGS="-static --target=riscv64-linux-gnu -march=rv64imafdc -Iposix" compile
mv coremark.exe coremark-llvm
