Building & Installing PowerTOP
------------------------------
just type
make
make install
Build dependencies
------------------
PowerTOP uses C++, and expects g++ and libstdc++ to be functional
in addition to that, it needs the following components:
pciutils-devel
ncurses-devel
zlib-devel
and a functional glibc/pthreads development environment
Outputting a report
-------------------
When invoking PowerTOP without arguments, it goes into interactive mode.
However, for reporting bugs etc there is a special reporting mode:
powertop --html
which will create a "powertop.html" file which is static and can be sent to
others to help diagnose power issues.
Calibrating & Power Numbers
---------------------------
PowerTOP will, when running on battery, track your power consumption as well
as your activity on the system. Once there are sufficient such measurements,
PowerTOP can start to report power estimates for various activities.
You can help get this estimation more accurate by running a calibration
cycle:
powertop --calibrate
at least once; this will cycle through various display brightness levels
(including "off") as well as USB device activities and some other workloads.
