Add the ACPI Asus extras driver. Provides support for cool ACPI-controled
gadgets (hotkeys, lcd, ...) on Asus laptops. I aim to closely track the acpi4asus project which implements these features in the Linux kernel. If this breaks your laptop, please let me know how it does it :-) Approved by: njl (mentor)

.Sh SYNOPSIS
|
||||
.Cd "device acpi_asus"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides support for the extra ACPI-controlled gadgets, such as hotkeys
|
||||
and leds, found on recent Asus (and Medion) laptops.
|
||||
It allows one to use the
|
||||
.Xr sysctl 8
|
||||
interface to manipulate the brightness of the LCD panel and the display output
|
||||
state.
|
||||
Hotkey events are passed to
|
||||
.Xr devd 8
|
||||
for easy handling in userspace.
|
||||
.Pp
|
||||
Currently, the following laptops are fully supported:
|
||||
.Pp
|
||||
.Bl -tag -width ident -compact
|
||||
.It L2D
|
||||
.It L3C
|
||||
.It L3D
|
||||
.It L3H
|
||||
.It L8L
|
||||
.It M1A
|
||||
.It M2E
|
||||
.El
|
||||
.Pp
|
||||
.Sh SYSCTLS
|
||||
The following sysctls are currently implemented:
|
||||
.Bl -tag -width indent
|
||||
.It Va hw.acpi.asus.lcd_brightness
|
||||
Makes the LCD backlight brighter or dimmer (higher values are brighter).
|
||||
.It Va hw.acpi.asus.lcd_backlight
|
||||
Turns the LCD backlight on or off.
|
||||
.It Va hw.acpi.asus.video_output
|
||||
Sets the active display to use according to a bitwise OR 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
|
||||
Some models also support video switching via the generic
|
||||
.Xr acpi_video 4
|
||||
driver. Most models don't, however.
|
||||
.El
|
||||
.Pp
|
||||
Defaults for these variables can be set in
|
||||
.Xr sysctl.conf 5 ,
|
||||
which is parsed at boot-time.

||||

.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
driver first appeared in
|
||||
.Fx 5.3 .
|
||||
.Sh AUTHORS
|
||||
.An -nosplit
|
||||
The
|
||||
.Nm
|
||||
driver and this manual page were written by
|
||||
.An Philip Paeps Aq philip@FreeBSD.org .
|
||||
.Pp
|
||||
Inspiration came from the
|
||||
.Em acpi4asus project
|
||||
started by Julien Lerouge which maintains a driver implementing this
|
||||
functionality in the Linux kernel.
