为了VS-RK3399达到最好的性能,需要将CPU 及GPU 定频,特别是GPU。
CPU 定频方法参考:
cat /sys/devices/system/cpu/cpu4/cpufreq/scaling_available_frequencies
echo "userspace" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "1416000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
echo "userspace" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo "1416000" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_setspeed
echo "userspace" > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo "1416000" > /sys/devices/system/cpu/cpu2/cpufreq/scaling_setspeed
echo "userspace" > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor
echo "1416000" > /sys/devices/system/cpu/cpu3/cpufreq/scaling_setspeed
echo "userspace" > /sys/devices/system/cpu/cpu4/cpufreq/scaling_governor
echo "1800000" > /sys/devices/system/cpu/cpu4/cpufreq/scaling_setspeed
echo "userspace" > /sys/devices/system/cpu/cpu5/cpufreq/scaling_governor
echo "1800000" > /sys/devices/system/cpu/cpu5/cpufreq/scaling_setspeed
GPU 定频方法参考:
echo "userspace" >/sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/governor
echo "800000000" >/sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/userspace/set_freq
cat /sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/cur_freq
