# adjusts /etc/defaults/cpufrequtils to control board consumption. Works

|
# Background information:
|
||
|
|
#
|
||
|
|
# By controlling a few settings energy consumption of H3 boards can be
|
||
|
|
# influenced:
|
||
|
|
#
|
||
|
|
# - disabling GPU/HDMI on headless devices: 210 mW less idle consumption
|
||
|
|
# (memory bandwidth also increases so performance will slightly improve)
|
||
|
|
#
|
||
|
|
# - negotiate only Fast Ethernet on GbE devices: 370 mW less idle consumption
|
||
|
|
#
|
||
|
|
# - switch off Ethernet on Fast Ethernet devices: 200 mW less idle consumption
|
||
|
|
#
|
||
|
|
# - limit max cpufreq: does not affect idle consumption but peak/full load
|
||
|
|
# (using 912 mhz on NanoPi M1/NEO or Orange Pi One/Lite will prevent VDD_CPU
|
||
|
|
# switching to the higher voltage and therfore greatly reduce consumption
|
||
|
|
# with only a slight decrease in maximum performance)
|
||
|
|
#
|
||
|
|
# - limit count of active cpu cores: low impact on idle consumption, high on
|
||
|
|
# peak/full load consumption
|
||
|
|
#
|
||
|
|
# - lower DRAM clockspeed to 408 MHz: 150 mW less idle consumption
|
||
|
|
#
|
||
|
|
# - disabling all USB ports (it's only 'all or nothing'): 125 mW less idle
|
||
|
|
#
|
||
|
|
# Please be aware that WiFi might add significantly to consumption. Since there
|
||
|
|
# are too many possible configurations (USB WiFi dongles also considered and
|
||
|
|
# possibilities to tweak power management settings with individual WiFi chips)
|
||
|
|
# h3consumption does not adjust WiFi settings -- only the -p switch lists
|
||
|
|
# configured WiFi devices.
|
||
|
|
#
|
||
|
|
# In case you don't need WiFi on the H3 boards with onboard WiFi adjust
|
||
|
|
# /etc/modules and comment the WiFi module out (8189es, 8189fs or bcmdhd).
|
||
|
|
# Please keep also in mind that you can control networking consumption also
|
||
|
|
# on a 'on demand' basis. In case you use a H3 board as data logger and need
|
||
|
|
# WiFi only for a short time every 24 hours, disabling WiFi and only enabling
|
||
|
|
# it for data transfers will save you between 300 and 1000 mW with 8189FTV as
|
||
|
|
# used on Orange Pi Lite, PC Plus or Plus 2E for example:
|
||
|
|
#
|
||
|
|
# ifconfig wlan0 down && rmmod -f 8189fs / modprobe 8189fs && sleep 0.5 && ifconfig wlan0 up
|
||
|
|
#
|
||
|
|
# Same with the Gigabit Ethernet equipped H3 boards: switching there to Fast
|
||
|
|
# Ethernet when no high speed transfers are needed saves a whopping 370 mW
|
||
|
|
# (and the same will happen on the switch's side if a more modern Gbit switch
|
||
|
|
# is in use):
|
||
|
|
#
|
||
|
|
# ethtool -s eth0 speed 100 duplex full / ethtool -s eth0 speed 1000 duplex full
