too, so, instead of descending to the i386 directory, we add some magic to the parent Makefile. These man pages refer to drivers that I'm aware that work on amd64. Most likely there are more, but I'll deal with them later. Approved by: brueffer, philip, takawata

.Sh NAME
|
|
.Nm acpi_toshiba
|
|
.Nd Toshiba HCI interface
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device acpi_toshiba"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
acpi_toshiba_load="YES"
|
|
.Ed
|
|
.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 SYSCTL VARIABLES
|
|
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 LOADER 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 .
