Rockchip 提供 npu 测试脚本
# ls /rockchip-test/npu2
model npu_freq_scaling.sh npu_stress_test.sh npu_test.sh
npu 频率测试脚本 npu_freq_scaling.sh
usage()
{
echo "Usage: npu_freq_scaling.sh [test_second] [every_freq_stay_second]"
echo "example: ./npu_freq_scaling.sh 3600 30"
echo "means npu_freq_scaling.sh will run 1 hour and every cpu frequency stay 30s"
}
示例：npu变频运行60秒，每10秒变频一次
# ./npu_freq_scaling.sh 60 10
test will run 60 seconds
every npu frqeucny will stay 10 seconds
