NAME
     sony — Sony Miscellaneous Controller

SYNOPSIS
     sony*    at acpi?

DESCRIPTION
     Some Sony notebook computers have a controller that handles various
     built-in devices.	The sony driver provides support for accessing/modify‐
     ing the settings of some of these devices via the sysctl(8) interface.

     The following sysctl(8) variables are available:

     hw.sony0.brt [R/W]	 Controls current LCD brightness.  Range [0-8].
     hw.sony0.pbr [R/W]	 Controls power on LCD brightness.  Range [0-8].
     hw.sony0.cdp [R/W]	 Controls CD power.
     hw.sony0.pid [R/O]	 Unknown
     hw.sony0.ctr [R/W]	 Unknown
     hw.sony0.pcr [R/W]	 Unknown
     hw.sony0.cmi [R/W]	 Unknown
     hw.sony0.ams [R/W]	 Audio control (mute when 0)
     hw.sony0.hke [R/O]	 Indicates a Host Key Event.  Bits are set when an
			 event occurs and cleared when this value is read.
			 The following table describes the bit set for each
			 button pressed:

			       0x1000  S1 button
			       0x0800  S2 button
			       0x0200  Fn + F10 (magnify)
			       0x0100  Mute button
			       0x0020  Fn + F12 (suspend to disk)
			       0x0010  Fn + F7 (LCD/external monitor)
			       0x0008  Fn + F6 (brighter backlight)
			       0x0004  Fn + F5 (darker backlight)
			       0x0002  Fn + F4 (volume up)

AUTHORS
     Sami Kantoluoto for the original driver and manual information.  Christos
     Zoulas for cleaning up the driver and this manual page.

BUGS
     ·	 The sony driver just parses integer values from the acpi(4) tree.  It
	 could be more intelligent and parse other controls.

     ·	 The sysctl(8) interface is not great.	The names of the sysctl(8)
	 tree are not self-explanatory.

     ·	 No validity checks are performed on the user input.  Playing with
	 random values and/or unknown controls can harm your machine.

     ·	 The name of the driver is too generic.
