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.
