# h3consumption
#
# This tool patches fex/script.bin, adds commands to /etc/rc.local and
# adjusts /etc/defaults/cpufrequtils to control board consumption. Works
# only with H3 devices running legacy kernel.
#
#############################################################################
#
# 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

#############################################################################
#
# TODO:
#
# - Write documentation as nicely as it's done for h3disp
# - Allow higher DRAM clock in fex file than set from /etc/rc.local
# - Add revert mode, relinking original fex/bin and restore all original
# settings
