======================================================================
A.For Query GPU/CPU related Command:
  cat /proc/mali/utilization
  cat /proc/mali/frequency
  cat /proc/mali/memory_usage
======================================================================
B.For Fix GPU Frequency:
  echo > (450000, 280000) /proc/gpufreq/gpufreq_opp_freq
  echo 0 > /proc/gpufreq/gpufreq_opp_freq(re-enable GPU DVFS)
C.For Turn On/Off CPU core number:
  echo (1, 0) > /sys/devices/system/cpu/cpu1/online
  echo (1, 0) > /sys/devices/system/cpu/cpu2/online
  echo (1, 0) > /sys/devices/system/cpu/cpuN/online
D.For CPU Performance mode(Force CPU to run at highest speed:
 echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
 echo interactive > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor(re-enable CPU DVFS)
==============================================================================================
E.For GPU advanced debugging command:
 echo [dvfs_freq(ms)] > /proc/mali/dvfs_freq
 echo [dvfs_thr_max] [dvfs_thr_min] > /proc/mali/dvfs_threshold
 echo [dvfs_deferred_count] > /proc/mali/dvfs_deferred_count
