#NOTE: dvc_update_volt.sh is set as root-only executable in read only directory /sbin/
#NOTE: better to move dvc_update_volt.sh to writtable directory, such /data
#NOTE: better to remove dvc_update_volt.sh after doing system test
#NOTE: be careful to check if dvc_update_volt.sh is executed correctly from dmesg log
#NOTE: dvc_update_volt.sh is to reduce voltage before doing stress test
#NOTE: default is reduce 25mv in dvc_update_volt.sh, can change it to other value if needed
