.Sh NAME
.Nm acpi_toshiba
.Nd Toshiba HCI Interface
.Sh SYNOPSIS
.Cd device acpi_toshiba
.Sh DESCRIPTION
HCI is Toshiba's
.Em Hardware Control Interface
which is somewhat uniform across their models.
The
.Nm
driver allows the user to manipulate HCI-controlled hardware using a number of
.Xr sysctl 8
variables.
.Sh SYSCTLS
The following sysctls are currently implemented:
.Bl -ohang -offset indent
.It Va hw.acpi.toshiba.force_fan
Causes active cooling to be forcibly enabled ('1') or disabled ('0')
regardless of the current temperature.
.It Va hw.acpi.toshiba.video_output
Sets the active display to use according to a bitwise OR of the following:
.Pp
.Bl -tag -width 10 -offset indent -compact
.It 0
No display
.It 1
LCD
.It 2
CRT
.It 4
TV-Out
.El
.It Va hw.acpi.toshiba.lcd_brightness
Makes the LCD backlight brighter or dimmer (higher values are brighter).
.It Va hw.acpi.toshiba.lcd_backlight
Turns the LCD backlight on and off.
.It Va hw.acpi.toshiba.cpu_speed
Sets the CPU speed to the specified speed.
This provides similar functionality to the
.Em hw.acpi.cpu.throttle_state
variable.
Note, however, that higher values mean higher speeds here.
.El
.Pp
Defaults for these variables can be set in
.Xr sysctl.conf 5 ,
which is parsed at boot-time.
.Sh TUNABLES
The
.Em hw.acpi.toshiba.enable_fn_keys
tunable enables or disables the function keys on the keyboard.
Function keys are enabled by default.
.Pp
This behaviour can be changed at the loader prompt or in
.Xr loader.conf 5 .
