tpctl -- touch panel calibration utility SYNOPSIS
tpctl [-D dispdevname] [-d devname] [-f filename] [-hnuv] DESCRIPTION
tpctl is a touch panel calibration utility. tpctl calibrates a touch panel and saves and restores the calibration parameters into/from a parameter database file. Available command-line flags are: -D dispdevname Specify display device name. -d devname Specify touch panel device name. -f filename Specify alternate parameter database file name. -h Print brief description. -n Do not change the parameter database file. -u Force calibration. Without this flag, tpctl won't do calibration if the database file already contains parameters for the touch panel. -v Verbose mode. You calibrate the touch panel the first time you run tpctl. If you see a cross cursor on the screen, you should tap the center of the cursor to calibrate the touch panel, or you can abort the calibration with the 'ESC' key. Five cursors will appear on the screen in turn. Once calibration is done, tpctl saves the calibration parameters into the database file and uses the saved parameters to calibrate the touch panel. You can run tpctl automatically with /etc/rc.d/tpctl. FILES
/etc/tpctl.dat The default calibration parameter database file. The -f flag may be used to specify an alternate database file name. tpctl will create an empty database file if it doesn't exist. /dev/ttyE0 The default display device, which is used to display the cursor during calibration. The -D flag may be used to specify an alternate display device name. The display device must provide the 'hpcfb' interface as defined in /usr/include/dev/hpc/hpcfbio.h. /dev/wsmux0 The default touch panel device. The -d flag may be used to specify an alternate touch panel device name. SEE ALSO
rc.conf(5) BUGS
tpctl isn't available on all ports because it requires a display device which provides the 'hpcfb' interface. BSD

powertop - a power consumption and power management diagnosis tool. SYNOPSIS
powertop [ options ] DESCRIPTION
powertop is a program that helps to diagnose various issues with power consumption and power management. It also has an interactive mode allowing one to experiment with various power management settings. When invoking powertop without arguments powertop starts in interactive mode. OPTIONS
--csv[=FILENAME] generate a CSV report. If a filename is not specified then the default name "powertop.csv" is used. The CSV report can be used for reporting and data analysis. --calibrate runs powertop in calibration mode. When running on battery, powertop can track power consumption as well as system activity. When there are enough measurements, powertop can start to report power estimates. One can get more accurate estimates by using this option to enable a calibration cycle. This will cycle through various display levesl and USB device activities and workloads. --debug run in "debug" mode. --extech=devnode use the Extech Power Analyzer for measurements. This allows one to specify the serial device node of the serial to USB adaptor con- necting to the Extech Power Analyzer, for example /dev/ttyUSB0. --help show the help message. --html[=FILENAME] generate an HTML report. If a filename is not specified then the default name "powertop.html" is used. The HTML report can be sent to others to help diagnose power issues. --iteration[=iterations] number of times to run each test. --time[=seconds] generate a report for a specified number of seconds. --version print version information and exit.
