Battery voltage obtained from BD2613GW PMIC (ADC used for digitize voltage). CPU usage obtained from intel-rapl (ujoules converted to watts). Program tested on the folowing platforms:
- Personal mobile Linux server (aka "Joker") - http://jokersys.com
- Microsoft Surface 3 (not 'pro' version) with Debian Linux
Before compilation please install following package:
apt-get install libi2c-dev
and then you can start compilation:
mkdir build
cd build
cmake ../
make
now you can start monitoring:
# ./joker-power
ts=1479612120 total_uj=1349088 watts=1.349088 voltage=4.169110
ts=1479612121 total_uj=2526272 watts=1.177184 voltage=4.169110
ts=1479612122 total_uj=3686688 watts=1.160416 voltage=4.169110
ts=1479612123 total_uj=4884320 watts=1.197632 voltage=4.178886
ts=1479612124 total_uj=6111712 watts=1.227392 voltage=4.173998
ts=1479612125 total_uj=7297344 watts=1.185632 voltage=4.173998
usage:
-i interval in seconds, default:1
-b i2c_bus_id default:1
-o outfile default:none
to check BD2613GW PMIC availability you can use i2cdetect command:
# i2cdetect -ry 1 0x03 0x70

address 0x5e and 0x6e should be in this output.
notes: be sure that the following kernel modules are loaded:
modprobe i2c_designware_platform
modprobe i2c_dev
modprobe intel_rapl
otherwise you need to recompile your kernel with this modules enabled.
