Add acpi_asus_wmi(4) -- driver for random extras found on WMI-compatible
Asus laptops. It is alike to acpi_asus(4), but uses WMI interface instead of separate ACPI device. On Asus EeePC T101MT netbook it allows to handle hotkeys and on/off WLAN, Bluetooth, LCD backlight, camera, cardreader and touchpad. On Asus UX31A ultrabook it allows to handle hotkeys, on/off WLAN, Bluetooth, Wireless LED, control keyboard backlight brightness, monitor temperature and fan speed. LCD brightness control doesn't work now for unknown reason, possibly requiring some video card initialization. Sponsored by: iXsystems, Inc.

.Sh NAME
|
||||
.Nm acpi_asus_wmi
|
||||
.Nd Asus Laptop WMI Extras
|
||||
.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_asus_wmi"
|
||||
.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_asus_wmi_load="YES"
|
||||
.Ed
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides support for the extra WMI-controlled gadgets, such as hotkeys
|
||||
and leds, found on Asus laptops.
|
||||
It allows one to use the
|
||||
.Xr sysctl 8
|
||||
interface to manipulate the brightness of the LCD panel and keyboard backlight,
|
||||
power on/off different internal components, such as WiFi, Bluetooth, camera,
|
||||
cardreader, etc, read some sensors.
|
||||
Hotkey events are passed to
|
||||
.Xr devd 8
|
||||
for easy handling in userspace with the default configuration in
|
||||
.Pa /etc/devd/asus.conf .
|
||||
Some hotkey events, such as keyboard backlight and touchpad control, are
|
||||
handled inside the driver.
|
||||
.Sh SYSCTL VARIABLES
|
||||
The following sysctls are currently implemented:
|
||||
.Bl -tag -width indent
|
||||
.It Va dev.acpi_asus_wmi.0.handle_keys
|
||||
Specifies whether driver should handle some harwdare keys, such as keyboard
|
||||
backlight, internally.
|
||||
.El
|
||||
.Pp
|
||||
Number of other variables under the same sysctl branch are model-specific.
|
||||
.Pp
|
||||
Defaults for these variables can be set in
|
||||
.Xr sysctl.conf 5 ,
|
||||
which is parsed at boot-time.
|
||||

|
||||
The
|
||||
.Nm
|
||||
driver first appeared in
|
||||
.Fx 10.0 .
