RuyiSDK Performance Test Example

This example uses the RuyiSDK GCC and LLVM toolchains on a PC to cross-compile Coremark, then transfers the binaries to the development board for execution.

Install the ruyi package manager (see the official installation guide for other methods)

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

Install the GCC and LLVM toolchains

ruyi update
ruyi install gnu-ruyisdk llvm-ruyisdk

Coremark (GCC)

Create and activate a ruyi virtual environment (GCC)

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

Verify the GCC version

riscv64-ruyisdk-linux-gnu-gcc -v

Compile 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

Transfer the file from the PC

python3 -m http.server 8000

Run the following commands in the development board's minicom terminal:

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

Output

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

Correct operation validated. See README.md for run and reporting rules.

Exit the ruyi GCC virtual environment

cd ..; ruyi-deactivate

Coremark (LLVM)

Create and activate a ruyi virtual environment (LLVM)

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

Verify the LLVM version

clang -v

Compile Coremark (LLVM)

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

Strip the attributes section

OBJCOPY=~/tes/k510_buildroot/k510_crb_lp3_v1_2_defconfig/host/bin/riscv64-buildroot-linux-gnu-objcopy
if [ ! -f "$OBJCOPY" ]; then
    OBJCOPY=/opt/riscv64-lp64d--glibc--stable-2025.08-1/bin/riscv64-linux-objcopy
fi
 
$OBJCOPY --remove-section=.riscv.attributes coremark-llvm coremark_llvm

Transfer the file from the PC

python3 -m http.server 8000

Run the following commands in the development board's minicom terminal:

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