NAME
acpi_toshiba — Toshiba HCI interfaceSYNOPSIS
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 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: 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.
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).SEE ALSO
