|
|
.Nd "ACPI hotkey driver for Panasonic laptops"
|
|
.Sh SYNOPSIS
|
|
.Cd "device acpi_panasonic"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver enables such hotkey facilities of various Panasonic laptops as
|
|
changing LCD brightness, controlling mixer volumes, entering sleep or
|
|
suspended state and so on.
|
|
On the following models it is reported to work: Let's note (or
|
|
Toughbook, outside Japan) CF-R1N, CF-R2A and CF-R3.
|
|
It may also work on other models as well.
|
|
.Pp
|
|
The driver consists of three functionalities.
|
|
The first is to detect hotkey events and take corresponding actions,
|
|
which include changing LCD luminance and speaker mute state.
|
|
The second role is to notify occurences of the event by way of
|
|
.Xr devctl 4
|
|
and eventually to
|
|
.Xr devd 8 .
|
|
The third and last is to provide a way to adjust LCD brightness and
|
|
sound mute state via sysctl.
|
|
.Ss Hotkeys
|
|
There are 9 hotkeys available on the supported hardwares:
|
|
.Pp
|
|
.Bl -tag -compact -offset indent
|
|
.It Sy \&Fn+F1
|
|
Make LCD backlight darker.
|
|
.It Sy \&Fn+F2
|
|
Make LCD backlight brighter.
|
|
.It Sy \&Fn+F3
|
|
Switch video output between LCD and CRT.
|
|
Not supported by the
|
|
.Nm
|
|
driver.
|
|
.It Sy \&Fn+F4
|
|
Toggle muting the speaker.
|
|
.It Sy \&Fn+F5
|
|
Turn the mixer volume down.
|
|
.It Sy \&Fn+F6
|
|
Turn the mixer volume up.
|
|
.It Sy \&Fn+F7
|
|
Enter suspend-to-RAM state.
|
|
.It Sy \&Fn+F9
|
|
Show battery status.
|
|
.It Sy \&Fn+F10
|
|
Enter suspend-to-disk state.
|
|
.El
|
|
.Pp
|
|
Actions are automatically taken within the driver for
|
|
.Sy \&Fn+F1 ,
|
|
.Sy \&Fn+F2
|
|
and
|
|
.Sy \&Fn+F4 .
|
|
For the other events such as
|
|
mixer control and showing battery status,
|
|
.Xr devd 8
|
|
should take the role as described below.
|
|
.Ss Devd Events
|
|
When notified to
|
|
.Xr devd 8 ,
|
|
the hotkey event provides the following information:
|
|
.Pp
|
|
.Bl -tag -compact -offset indent
|
|
.It system
|
|
.Qq ACPI
|
|
.It subsystem
|
|
.Qq Panasonic
|
|
.It type
|
|
The source of the event in ACPI namespace.
|
|
The value depends on the model but typically
|
|
.Qq \e_SB_.HKEY .
|
|
.It notify
|
|
Event code (see below).
|
|
.El
|
|
.Pp
|
|
Event codes to be generated are assigned as follows:
|
|
.Bl -tag -offset indent
|
|
.It 0x81-0x86, 0x89
|
|
.Sy \&Fn+F<n>
|
|
pressed. 0x81 corresponds to
|
|
.Sy \&Fn+F1 ,
|
|
0x82 corresponds to
|
|
.Sy \&Fn+F2 ,
|
|
and so on.
|
|
.It 0x01-0x07, 0x09, 0x1a
|
|
.Sy \&Fn+F<n>
|
|
released. 0x01 corresponds to
|
|
.Sy \&Fn+F1 ,
|
|
0x02 corresponds to
|
|
.Sy \&Fn+F2 ,
|
|
and so on.
|
|
.El
|
|
.Sh SYSCTLS
|
|
The following read-write MIBs are available:
|
|
.Bl -tag -width indent
|
|
.It Va hw.acpi.panasonic.lcd_brightness_max
|
|
The max level of brightness.
|
|
The value ranges from 0 to 255.
|
|
CF-R1N and CF-R2A should be 255, CF-R3 is 31.
|
|
.It Va hw.acpi.panasonic.lcd_brightness
|
|
Current brightness level of the LCD.
|
|
The value ranges from 0 to
|
|
.Va hw.acpi.panasonic.lcd_brightness_max .
|
