My quick look at '''linux-intel-undervolt-tool''' files and behaviour:
/usr/bin/undervolt
  # program written in python
  # if run without elevated right it give command to apply yourself with wrmsr
  # options:
    '-gpu', type=int, help='Undervolt GPU by this amount of millivolts. Must be negative.'
    '-cpu', type=int, help='Undervolt CPU by this amount of millivolts. Must be negative.'
    '-config', type=str, help='Config file to load. Other flags has priority over -config.'
/etc/undervolt.json
  # contain voltage parameters "cpu" and "gpu"
/usr/lib/systemd/system/undervolt.service
  # a systemd service enabled and started which restart after suspend/hibernate/hybrid-sleep with: -config /etc/undervolt.json
/etc/modules-load.d/undervolt-msr.conf
  # load msr module at startup
