VS-RK3XXX 关于GPU和CPU性能

视壮T_19928853549

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
