RuyiSDK 性能测试示例

本示例可直接在开发板上编译并运行，适合初学者快速上手。

安装依赖包

sudo dnf install -y git make wget tar zstd xz

安装 ruyi 包管理器（其他安装方式见官方安装文档）

wget https://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.52.0/ruyi-0.52.0.riscv64
chmod +x ./ruyi-0.52.0.riscv64
sudo cp -v ./ruyi-0.52.0.riscv64 /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 toolchain/gnu-ruyisdk manual venv-gnu-ruyisdk
. venv-gnu-ruyisdk/bin/ruyi-activate

验证 GCC 版本

riscv64-ruyisdk-linux-gnu-gcc -v

获取、编译并运行 Coremark（GCC）

git clone https://github.com/eembc/coremark
cd coremark
 
make PORT_DIR=posix \
CC=riscv64-ruyisdk-linux-gnu-gcc \
XCFLAGS="-march=rv64imafdch_zicsr_zifencei_zca_zcd_zba_zbb -O2" \
compile
./coremark.exe

正常情况下，终端会看到类似如下输出：

«Ruyi venv-gnu-ruyisdk» [fedora@localhost coremark]$ make PORT_DIR=posix \
