ACPI_TOSHIBA(4) 					   BSD Kernel Interfaces Manual 					   ACPI_TOSHIBA(4)

NAME

     acpi_toshiba -- Toshiba HCI interface

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device acpi_toshiba

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   acpi_toshiba_load="YES"

DESCRIPTION

     HCI is Toshiba's Hardware Control Interface which is somewhat uniform across their models.  The acpi_toshiba driver allows the user to manip-
     ulate HCI-controlled hardware using a number of sysctl(8) variables.

SYSCTL VARIABLES

     The following sysctls are currently implemented:

     hw.acpi.toshiba.force_fan
	     Causes active cooling to be forcibly enabled ('1') or disabled ('0') regardless of the current temperature.

     hw.acpi.toshiba.video_output
	     Sets the active display to use according to a bitwise OR of the following:

	     0	     No display
	     1	     LCD
	     2	     CRT
	     4	     TV-Out

	     Only some systems (i.e., the Libretto L5) support video switching via this hardware-specific driver.  Use the acpi_video(4) driver
	     for generic video output support.

     hw.acpi.toshiba.lcd_brightness
	     Makes the LCD backlight brighter or dimmer (higher values are brighter).

     hw.acpi.toshiba.lcd_backlight
	     Turns the LCD backlight on and off.

     hw.acpi.toshiba.cpu_speed
	     Sets the CPU speed to the specified speed.  This provides functionality similar to the hw.acpi.cpu.throttle_state variable.  Higher
	     sysctl values mean lower CPU speeds.

     Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time.

LOADER TUNABLES

     The hw.acpi.toshiba.enable_fn_keys tunable enables or disables the function keys on the keyboard.	Function keys are enabled by default.

     This behaviour can be changed at the loader(8) prompt or in loader.conf(5).

ACPI_FUJITSU(4) 					   BSD Kernel Interfaces Manual 					   ACPI_FUJITSU(4)

NAME

     acpi_fujitsu -- Fujitsu Laptop Extras

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device acpi_fujitsu

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   acpi_fujitsu_load="YES"

DESCRIPTION

     The acpi_fujitsu driver enables the ACPI-controlled buttons on Fujitsu notebooks.	The button events are sent to userspace via devd(8), and a
     sysctl(8) interface is provided to simulate the hardware events.

     Using this driver, one can control the brightness of the display, the volume of the speakers, and the internal (eraserhead) mouse pointer.

SYSCTL VARIABLES

     These sysctls are currently implemented:

     hw.acpi.fujitsu.lcd_brightness
	     Makes the LCD backlight brighter or dimmer.

     hw.acpi.fujitsu.pointer_enable
	     Enables or disables the internal mouse pointer.

     hw.acpi.fujitsu.volume
	     Controls the speaker volume.

     hw.acpi.fujitsu.mute
	     Mutes the speakers.

     Defaults for these sysctls can be set in sysctl.conf(5).

EXAMPLES

     The following can be added to devd.conf(5) in order to pass button events to a /usr/local/sbin/acpi_oem_exec.sh script:

	   notify 10 {
		   match "system"	   "ACPI";
		   match "subsystem"	   "FUJITSU";
		   action "/usr/local/sbin/acpi_oem_exec.sh $notify fujitsu";
	   };

     A possible /usr/local/sbin/acpi_oem_exec.sh script might look like:

	   #!/bin/sh
	   #
	   if [ "$1" = "" -o "$2" = "" ]
	   then
		   echo "usage: $0 notify oem_name"
		   exit 1
	   fi
	   NOTIFY=`echo $1`
	   LOGGER="logger"
	   CALC="bc"
	   BC_PRECOMMANDS="scale=2"
	   ECHO="echo"
	   CUT="cut"
	   MAX_LCD_BRIGHTNESS=7
	   MAX_VOLUME=16
	   OEM=$2
	   DISPLAY_PIPE=/tmp/acpi_${OEM}_display

	   case ${NOTIFY} in
		   0x00)
			   LEVEL=`sysctl -n hw.acpi.${OEM}.mute`
			   if [ "$LEVEL" = "1" ]
			   then
				   MESSAGE="volume muted"
			   else
				   MESSAGE="volume unmuted"
			   fi
			   ;;
		   0x01)
			   LEVEL=`sysctl -n hw.acpi.${OEM}.pointer_enable`
			   if [ "$LEVEL" = "1" ]
			   then
				   MESSAGE="pointer enabled"
			   else
				   MESSAGE="pointer disabled"
			   fi
			   ;;
		   0x02)
			   LEVEL=`sysctl -n hw.acpi.${OEM}.lcd_brightness`
			   PERCENT=`${ECHO} "${BC_PRECOMMANDS} ; 
				    ${LEVEL} / ${MAX_LCD_BRIGHTNESS} * 100" |
				    ${CALC} | ${CUT} -d . -f 1`
			   MESSAGE="brightness level ${PERCENT}%"
			   ;;
		   0x03)
			   LEVEL=`sysctl -n hw.acpi.${OEM}.volume`
			   PERCENT=`${ECHO} "${BC_PRECOMMANDS} ; 
				   ${LEVEL} / ${MAX_VOLUME} * 100" | 
				    ${CALC} | ${CUT} -d . -f 1`
			   MESSAGE="volume level ${PERCENT}%"
			   ;;
		   *)
			   ;;
		   esac
		   ${LOGGER} ${MESSAGE}
		   if [ -p ${DISPLAY_PIPE} ]
		   then
			   ${ECHO} ${MESSAGE} >> ${DISPLAY_PIPE} &
		   fi
	   exit 0
