Suspend

  • Step 1 : Power on DUT

  • Step 2 : Wait for the system to initialize, about 1-2 minutes

  • Step 3 : Set the system to suspend mode.

    echo mem > /sys/power/state

  • Step 4 : The console cannot input commands, which means it enters suspend

  • Step 5 : Wait for 1 minute and start measuring

Note : To disable Ethernet, you can set the Ethernet status to ‘disabled’ in the kernel and U-Boot DTS files.

Idle

  • Step 1 : Power on DUT

  • Step 2 : Wait for the system to initialize, about 1-2 minutes

  • Step 3 : Turn off some extra services

    systemctl stop NetworkManager.service
echo off > /sys/class/drm/card0-DSI-1/status

  • Step 4 : Wait for 1 minute and start measuring
