1-cpu 满负荷
查看cpu 在线情况：
#cat /sys/devices/system/cpu/online
#nproc 查看cpu 的数量

stress -c 6 //这个时候cpu 可以跑满

cpu 也可以进行单独调频

# 查看当前的cpu频率
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 
# 查看可设置的cpu频率
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
# 查看最大cpu频率
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 
# 更改最大cpu频率
echo 1907200 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 
# 查看最小cpu频率
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 
# 更改最小cpu频率
echo 1907200 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq 
# 查看可用的cpu频率模式
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governor
# 查看当前的cpu频率模式
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
# 设置 性能 频率模式
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
# 设置 用户态 频率模式
echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
# 如果用户选择了userspace模式, 那么可以设置cpu工作主频率到某一个指定值
echo 1907200 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

2- GPU

git clone https://github.com/anseeto/jetson-gpu-burn.git

cd jetson-gpu-burn

make

./gpu_burn 1000

# 查看当前的gpu频率
cat /sys/class/devfreq/17000000.gp10b/cur_freq 
# 查看可设置的gpu频率
cat /sys/class/devfreq/17000000.gp10b/available_frequencies
# 查看最大gpu频率
cat /sys/class/devfreq/17000000.gp10b/max_freq 
# 更改最大gpu频率
echo 1109250000 > /sys/class/devfreq/17000000.gp10b/max_freq 
# 查看最小gpu频率
cat /sys/class/devfreq/17000000.gp10b/min_freq 
# 更改最小gpu频率
echo 114750000 > /sys/class/devfreq/17000000.gp10b/min_freq 
# 查看可用的gpu频率模式
cat /sys/class/devfreq/17000000.gp10b/available_governors
# 查看当前的gpu频率模式
cat /sys/class/devfreq/17000000.gp10b/governor
# 设置 性能 频率模式
echo performance > /sys/class/devfreq/17000000.gp10b/governor
# 设置 用户 频率模式
echo userspace > /sys/class/devfreq/17000000.gp10b/governor
# 设置目标频率
echo 1109250000 > /sys/class/devfreq/17000000.gp10b/target_freq
