change the video output but use a separate device with a DSSX method and a HID of "TOS6201" instead. We use a pseudo-driver to get the handle for this object and pass it to the acpi_toshiba driver. This is untested but seems to match the Linux Toshiba driver.

.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 -tag -width indent
|
|
.It Va hw.acpi.toshiba.force_fan
|
|
Causes active cooling to be forcibly enabled
|
|
.Pq Ql 1
|
|
or disabled
|
|
.Pq Ql 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 indent -compact
|
|
.It Li 0
|
|
No display
|
|
.It Li 1
|
|
LCD
|
|
.It Li 2
|
|
CRT
|
|
.It Li 4
|
|
TV-Out
|
|
.El
|
|
.Pp
|
|
Only some systems (i.e., the Libretto L5) support video switching via
|
|
this hardware-specific driver.
|
|
Use the
|
|
.Xr acpi_video 4
|
|
driver for generic video output support.
|
|
.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 functionality similar to the
|
|
.Va hw.acpi.cpu.throttle_state
|
|
variable.
|
|
Higher sysctl values mean lower CPU speeds.
|
|
.El
|
|
.Pp
|
|
Defaults for these variables can be set in
|
|
.Xr sysctl.conf 5 ,
|
|
which is parsed at boot-time.
|
|
.Sh TUNABLES
|
|
The
|
|
.Va 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
|
|
.Xr loader 8
|
|
prompt or in
|
|
.Xr loader.conf 5 .
