    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.conf5:

    acpi_toshiba_load="YES"
    
     

    DESCRIPTION

    HCI is Toshiba's Hardware Control Interface which is somewhat uniform across their models. The driver allows the user to manipulate 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_video4 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.conf5, 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.conf5.
