DESCRIPTION

12       powertop  is a program that helps to diagnose various issues with power
13       consumption and power management.  It  also  has  an  interactive  mode
14       allowing one to experiment with various power management settings. When
15       invoking powertop without  arguments  powertop  starts  in  interactive
16       mode.

OPTIONS

19       --calibrate
20              runs powertop in calibration mode. When running on battery, pow‐
21              ertop can track power consumption as well  as  system  activity.
22              When there are enough measurements, powertop can start to report
23              power estimates. One can get more accurate  estimates  by  using
24              this  option  to  enable  a  calibration  cycle. This will cycle
25              through various display levels and  USB  device  activities  and
26              workloads.
27
28       -C[FILENAME], --csv[=FILENAME]
29              generate  a  CSV report. If a filename is not specified then the
30              default name "powertop.csv" is used. If  filename  is  "-"  then
31              STDOUT  is  used.   The CSV report can be used for reporting and
32              data analysis.
33
34       -d[FILENAME], --dump[=FILENAME]
35              generate a plain text report. If a filename is not specified  or
36              it is "-" then STDOUT is used.
37
38       --debug
39               run in "debug" mode.
40
41       --extech=devnode
42              use  the Extech Power Analyzer for measurements. This allows one
43              to specify the serial device node of the serial to  USB  adaptor
44              connecting   to   the   Extech   Power   Analyzer,  for  example
45              /dev/ttyUSB0.
46
47       --help
48               show the help message.
49
50       -r[FILENAME], --html[=FILENAME]
51              generate an HTML report. If a filename is not specified then the
52              default  name  "powertop.html"  is used. If filename is "-" then
53              STDOUT is used.  The HTML report can be sent to others  to  help
54              diagnose power issues.
55
56       --iteration[=iterations]
57              number of times to run each test.
58
59       --workload[=workload]
60              file to execute for workload.
61
62       --quiet
63               supress stderr output.
64
65       --time[=seconds]
66              generate a report for a specified number of seconds.
67
68       --version
69              print version information and exit.
