+.Sh NAME
+.Nm acpi_panasonic
+.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 .
+.It Va hw.acpi.panasonic.sound_mute
+A boolean flag to control whether to mute the speaker.
+The value 1 means to mute and 0 not.
+.El

+.\" .Sh HISTORY
+.\" The
+.\" .Nm
+.\" driver first appeared in
+.\" .Fx 5.3 .
+.Sh AUTHORS
+The
+.Nm
+driver and this manual page were written by
+.An OGAWA Takaya Aq t\-ogawa@triaez.kaisei.org
+and
+.An TAKAHASHI Yoshihiro Aq nyan@FreeBSD.org .
+.Sh BUGS
+The code is written in trial-and-error manner.
+There is no way to confirm the correctness except by
+.Dq it just works here .
